Induction melting of metals with a hand-held scheme. The principle of an induction furnace for melting various metals. Powering the crucible furnace

⁰

If you have a need for fired metals, ceramics, colored fuses and expensive metals, you can make your own such a simple pich. The majority of similar stoves cost a lot of pennies, according to the author, in this region, prices are in the region of $ 600-12000 per meal. In our opinion, the cost of the pich was only $ 120, except for the temperature regulator. Tsya is small, you can see the temperature is close to 1100 o C.

It is easy to choose self-reliance, all the details are not expensive, and they can be quickly replaced in case of a furnace failure.

Deyakі smart people are smart enough to make hoops, various talismans, brass knuckles and richly in such ovens.

Materials and tools for self-study:

Materials:
- bolt and nut (8x10, 1/4 inch);
- sіm fire-fighting clays (the stench is due to be soft, so that you will need to make grooves in them, expand 4 1/2 "x 9" x 2 1/2");
- a fold for folding ramie;
- A square sheet of metal for doors (author vikoristovuvav aluminum);
- heating element
- zharomitsn_ gvinti-contacts for krіplennya spiralі;
- shmatok cable(maє vitrimuvati as a minimum 10A).

3 tools:
- manual drill with a suitable nozzle for turning the grooves at the chain;
- wrench;
- Pliers;
- hacksaw;
- drill;
- wire cutters and more.

The process of preparing a self-propelled oven:

Croc first. Robimo grooves
First of all, it is necessary to signify, for the width of the helix, the depth and the width of the possible grooves at the chains are determined in a fallow way. Dali їх it is necessary to paint on zeglin with olive oil. The author of the groove has a shape that looks like the letter “U”, in the whole groove of such a shape two pieces are made, so that they are made on two chains. On the same center, as perebuvatim in the back of the oven, it is necessary to make two parallel grooves, as in the photo. As a result, after choosing the oven, the spiral takes off approximately “P”-like shape.

Croc is different. Installed heating element
Before installing the heating element, it is necessary to choose a heating element, having chosen from the dimensions of the furnace. It’s better for everything, cegla, as if I’m going to the stove, I’ll have a chance to rise, the shards of the two so twerk to make the bottom too big. You can drill them with a grinder with a disk for concrete, or you can use a superior winding disk.

And then you can install a spiral. Better for everything, її need to be stretched to the required length. If you wind the spiral yourself, then it is necessary to unravel, what kind of dozhina and comradeship you are guilty of buti drіt, on the Internet for this mass of information.

Well, then you can lay pich at the groove. For fixation of the spiral, the author of the vicorist metal bow, if you need to open it in ceglin. I would like to pay special attention to adding the connection of the spiral to the dart. Here it is the fault of the victors to use special screws with ceramic washers, and it is necessary to take the guarantee more. Otherwise, you will either burn steadily and stink of insulation, or you will burn steadily through the high temperature.

Our people have learned how to make such contacts from old car candles, if old electric tiles were broken from the open spiral.

Special respect should be given to the choice of material, from which the spiral is made. Vіd tsogo deposit the maximum temperature, yak can see pіch. Spiral may show great temperature volatility. For such purposes, the author chose the NiCr type. Most of these darts are guaranteed for a temperature of about 1340 o C. If you need other temperatures, you can choose another type of dart that suits you.

Crook the third. Robimo the frame of the pichka
For folding ramie, you need a little piece, you can twist steel and aluminum. Chotiri shmatki aluminum utvoryut nizhki, and two more go to the lower part and support the vag of all the chains. It is possible to vicorate for the folding of the lower support not two little pieces, but chotiri. Vtіm, it's not obov'yazkovo, as a result of the design, all the same is tightened with bolts and nuts, these bolts and trim the chain at the bottom.

At the upper part of the stove, it will be necessary to lay two or two tiles, as well as below. And if you pick everything up, you can look at the photo in detail.

Crook quarters. Robimo doors
A sheet of metal is needed for the folding of doors, the author is aluminium. On the back of the arch, it is necessary to paint a square or a chotirikutnik, fallow in the form of doors. Further, it is necessary to circle the square along the stake, having entered, it will be necessary to install for fixing the fireproof material. Well, then we’ll wiggle the shmatki along the kutakh, as you can see in the photo.

This is the fireproof material of the car made from the Kaowool stove. Її it is necessary to examine the size of the painted square. Well, then the slab is laid on the sheet, and the edges of the sheet, which are left out, are folded, and the stink of the slab itself is stifled.

The axis and everything, now the doors need to be hingedly fastened with screws and nuts to the stove, having drilled a couple of openings. In the yakost insulation material it is possible to vikoristovuvaty іnshі komplektuyuchі. You can rob the door buckle, or you can not.

Krok five. We supply electricity
To connect the spiral, it is necessary to twist good service with tovstoy Zhitlova, as you can see, as a minimum 10A. In addition, it is connected through a regulator, allowing you to trim the temperature in a given station. Also, you will need a thermometer, which will be more accurate to keep track of the temperature in the oven.

Induction pich - heating price, for melting steel, midi and other metals, the method of induction injection is used (metal is heated by streams, which are not affected by the change of the inductor field). Deyakі vvazhayut one of the types of scorching fittings support, prote vіdminnіst poliga ways of transferring energy metal that heats up. At the same time, electric energy becomes electromagnetic, then we become electric again, and it’s less likely to transform into thermal energy. Induction ovens are important find the best from all gas and electric ones (steel-smelting, small stoves), start their own heating method. With induction, heat is seen in the middle of the metal itself and the heat energy is the most efficient.

Induction ovens are divided into two types:

from the core (duct);
without a core (crucible).

Others are more respected by the present and brown ( opalyuvalni prilad from the core, through its attachment, obmezhenі in sweating). Crossing from the channel to the furnaces cob 1900s. At the moment, the stench is widely zastosovuyutsya at industry.

To finish popular such types of electrical appliances, like a muffle smelting furnace, a steel-smelting furnace and an arc steel-smelting furnace. The first ones are even more effective and safer in victories. On the shelves there is a great assortment of muffle furnaces of the same kind. An even more important role for metallurgy is to play such a wine as a steel-smelting pich. For її help, it became possible to heat up any materials.

However, at the present moment, melting has become more often carried out for the help of such a heating spore, as in them, for melting vicor, a thermal effect is achieved, and wine is more sturdy and practical.
With your own hands you can create a lot of clumsy heating structures. For example, it is already popular. As you have built the heating mini-design with your own hands, it is necessary to know its attachments. We have a lot of sights of induction furnaces, but we will describe less of them. If necessary, you can use the necessary schemes, chairs and video recordings.

Components of an induction furnace

For the simplest designs, there are only two main parts: an inductor and a generator. However, you can add your own, complete the unit for additional required circuits.
inductor
Heating cat is the most important warehouse. In it, absolutely all the work of the heating sporudi is to be deposited. For self-contained stoves with a small pressure, it is permissible to use an inductor with a bare copper tube with a diameter of 10 mm. The inner diameter of the inductor may be less than 80 mm. that is no more than 150 mm., Number of turns - 8-10. It is necessary to protect those that the coils are not guilty of sticking, so you can become 5-7 mm between them. Also, the same part of the inductor is not to blame for the tilt of the screen.
Generator
A friend for the importance of a warehouse furnace - a generator snake struma. When choosing a generator circuit, follow all unicati armchair, to give a zhorst spectrum strum. For those who do NOT need to choose, we will induce a popular circuit on a thyristor switch.

Powering the crucible furnace

In the middle there is a melting crucible with a pouring sock (“ comir“). From the outer side of the structure, at the vertical position of the expansion of the inductor. We gave a ball of thermal insulation, and a lid was opened to the beast. On the one hand, from the outer sides, it is possible to reveal the water struma and cold water. From the bottom there is an attachment signaling the removal of the crucible.

The melting crucible is one of the most important storage units, which signifies the operational reliability of the world. To that, before the crucible and other materials are presented even more powerful.

How to work induction pich

On the other hand, it is necessary to select a generator for the inductor. Here you need the diagram K174XA11. The transformer can be wound on a mini-ring with a diameter of 2 centimeters. The entire winding is wired with a wire with a diameter of 0.4 centimeters and may become 30 turns. For the primary winding, the presence is characteristic exactly 22 turns of a dart with a diameter of 1 mm, and in the second may be mitigated total 2-3 turns such a dart, but already folded four times. The inductor needs to be 3 mm thick. dart with a diameter of 11 mm. May buti equal 6 turns. To improve the resonance, the best way to install the greatest abo min svetlodiod.

MELTING FURNACE - tse attachments, applications for melting charge of black or color metal. The advantage is that the smelter mass is well mixed, as if the induction smelter is victorious for melting metal, for the fluff of vortex electric streams. We need a swimming stove good characteristics? ZAVODRR- transistor, thyristor furnaces for midi, chavun, aluminium, steel for 5 - 5000 kg.

How are the smelting furnaces powered?

How to upgrade the smelter? MELTING FURNACES - CE garniy way melt like black, and colored metals, like aluminum, steel, chavun, stainless steel, copper. Induction smelting furnaces are not foldable attachments, work under the power of an electromagnetic field, building evenly mix metal during the melting hour. On induction furnaces there is a lid and attachments for pouring metal into a livar kіvsh. The company ROSINDUKTOR promotes the smelting furnace of a transistor or thyristor viconan on the reducer and hydraulics.

The advantage of furnaces on the reducer is the possibility of manual (emergency) heating of metal, hydraulics - the smoothness of the melting unit. The melting furnaces are supplied with one or two melting units, an inductor is placed in the middle of the skin melting unit. The coil inductor looks like a mid-range cat, which is made up of impersonal coils, the tube can be either round or rectangular cut.

The cooling of the smelter is carried out behind the help of a chiller or a cooling tower. Before the melting hour, the metal needs to be cooled down by two circuits: the reactor (shown in the middle of the thyristor converter) and the inductor of the melting unit itself. The melting vuzol can have two options for the crucible: graphite and lining (wound manually from the lining bag). Graphite crucibles are vicorous for remelting colored metals, vicorous lining is used for black metals.

Melting furnaces - transistor

Transistor induction smelter is recognized for charge of black and color metals. It is built on the basis of a medium-frequency induction heating, which is a choice for additional MOSFET transistors and IGBT modules, which allows you to save on electricity up to 35%, with a high KKD of 95%.

Induction smelting furnaces based on transistors are suitable for small industrial enterprises, which need to melt a small amount of metal. From the advantages of melting furnaces, one can note their mobility and ease of maintenance, because the stench of vicorous graphite crucible, save an hour for lining preparation and drying.

The company Rosinductor promotes to buy induction melting furnaces LEGNUM (Taiwan), Russian buyers. The thyristor induction smelter Legnum is supplied with two modifications on hydraulics and gearboxes, the main purchases are medium and large smelters with a productivity of 2000 tons / river.

At the set of delivery of the induction melting furnace, there are two melting nodes, the stinks are installed on the back of the preparations for the foundation. The main advantages are economy on average by 20-30% economy for any other analogues presented on Russian market, superior, contemporary design and available price. Rosinductor supplies induction smelting furnaces not only in all regions of Ukraine, but also in the edge of the large SND. Returning to our company, be a singing induction melter, as you buy, we can be guaranteed best price, yakіst, nadіynіst that mind postachannya.

Advantages of melting metal in melting furnaces - economy. It is seen through the sight of a great amount of heat when metal is heated, the furnace is reduced by a small amount of pressure. If it works better between transistor and thyristor furnaces, then the first savings are 25%, and even if the pressure is the same, it’s worth remembering. The widest furnaces with a melting temperature of 1650 ° C, for this temperature it is possible to melt a refractory charge.

Instantly the melting of the metal is controlled by a mechanical method or remotely. In both cases, the process is the responsibility of the trained personnel, which may have been allowed by that tolerance. The Rosinductor company is working on improving the work of reworking, correcting malfunctions and improving the melting state in the work station.

When choosing a melting furnace, it is necessary to think about the choice of a crucible. Wherever it is deposited, what metal will melt and how many melts of wine can be seen. The average crucible shows 20 to 60 melts. For the long-term service of the crucible, it is necessary to victorious and original materials. An hour of melting metal takes no more than 50 hvilin on the heating of the smelting furnace, and even a small volume and tightness can lead to high productivity.

The delivery set of the melting furnace includes the main elements: thyristor or transistor frequency changeover, melting units, capacitor banks, templates, water-cooling cables, control panels, cooling systems.

Induction melting furnace 5 - 5000 kg

Induction melting crucible 5 - 5000 kg melting, in a light body made of aluminum alloy, with a TFC and a screwed reducer. Induction furnace crucible with thyristor conversion is recognized for melting black and color metals at livar plants. Pіch vikoristovuєtsya for heating melted midi, steel and chavun. The welfare mode of the robot oven is possible for consumption.

Melting furnaces for aluminum

Melting furnaces for aluminum may have their own peculiarities, even if the melting temperature of aluminum becomes 660 °C (390 kJ / kg). When choosing a furnace for aluminum, you are guilty of nobility, that the thyristor convertor is not to blame but the smelter, and the smelting vuzol itself is blown by its dimensions in the vzl of the vuzla for steel or midi in 2-3 times. Obviously, it is not recommended in the new smelting of other metals.

It is possible to melt aluminum alloys in furnaces with naphtha, gas and electric heating, in half-moist furnaces, but the most high-grade metal and high speed can be used during melting in induction melting furnaces, for the furnaces of the same charge warehouse,

Smelting furnaces for steel

Smelting furnaces are heated to their maximum temperature when melting steel 1500 - 1600 ° C and are accompanied by folding physical and chemical processes. When remelting steel, it is necessary to reduce the acidity, sulfur and phosphorus, which dissolve oxide and sulfide elements, which reduce the steel grade.

The peculiarity of steel melting in melting furnaces is the replacement of lining sums, at the top of the copper melting, the graphite crucible is installed. The smelting furnaces kindly mix the metal for the shell of the induction field, as if virіvnyuє khіmіchny warehouse of steel.

Indicated higher values are suitable for melting of alloyed steels, with minimal inputs of alloying elements: tungsten - close to 2%, manganese, chromium and vanadium - 5 - 10%, silicon - 10 - 15%, and high deficiency of light elements.

The melting of steel has the following special features:

The most important forks melt, vicarious method of oxidation, even if the metal boils for an hour, all non-metal inclusions are visible, and there is a decrease in phosphorus. The charge warehouse is taken from the bulk of carbon steels or chavun, in order to achieve an average total of 0.5% coal;
If you choose to melt steel with high manganese, aluminum, chromium, you need to choose an acid lining, even if the stability of the crucible will be double;
Before the cob of smelting, the crucible is clogged with metal, but the top is not next to be hammered in, or you can bring the crypts and the metal to death, so that the charge will settle for the first hour of melting the lower shmatkiv;
The hour of smelting began to become at 50-70 hvilin, fallow in the smelter;
Smelting furnaces for steel, can be highly productive with the production of forgings in a small mass and size.

Copper, copper metals, bronze, brass can be melted in all smelting furnaces, the temperature regime is 1000 - 1300 °C. However, it is better to use induction melting furnaces, since one melting in them does not exceed 40 quills. Mіd, like today victorious in Russia, is not distinguished by special purity. Call out to take revenge on such houses: zalizo, nickel, surma, mish'yak. We use clean metal to use copper from a house of 1%.

The main important is the quality of the metal - the high indicators of electrical conductivity and thermal conductivity. The temperature is low for melting. The melting temperature of midi is 1084°С. Mіd є to finish with gnuchka metal, which is widely vicorous in various technical galleys of craftsmanship, the axis of deakі її osobennosti:

It is possible to melt copper in a hot medium, in a vacuum and a medium in cold gases;
Melt copper in a vacuum to remove acid-free midi, with the possibility of reducing O (Oxygenium) practical acid to zero 0.001%;
The main charge at otrimanny bezkisnevoy midi - tse cathode leaves 99.95%, before that, how to zavantazhit leaves in pіch it is necessary to cut them, wash and dry them in the electrolyte;
The lining of the smelting furnace is smelted with magnesite for rіven metal;
In order to avoid oxidation, melting is carried out from the zastosuvannya of wooden vugill, fluxes, a warehouse and other components.

Induction furnace for metal melting

Induction furnace for melting metal heats the mixture of metal with high frequency jets (HFC) in an electromagnetic field, which is induced, under the influx of vortex electric jets. The smelting furnaces are used to generate a large amount of electricity, so we propagate the furnaces not only with a thyristor converter, but also with a transistor economy. Pekti vikoristovuyu lining or graphite crucible, in both stages їх vistachaє tilki 20-40 heats. The high melting temperature allows one melting of the metal for 50 minutes.

ZAVODRR- furnaces for melting metals of Russian, Asian and European varieties from a crucible capacity of 1 to 10,000 kg. Delivery, installation, start-up and maintenance of furnaces is not expensive.

Let's take a look at the features of furnaces for melting black, colored and expensive metals:

Furnaces for melting aluminum (melting aluminum in furnaces vibrates at a temperature of 660 ° C, boiling point 2400 ° C, thickness 2698 kg / cm³);
Pitch for melting chavun (melting chavun 1450 - 1520 °C, thickness 7900 kg/m³);
Pectas for melting midi (melting midi 1083°C, boiling point 2580°C, thickness 8920 kg/cm³);
Pects for melting gold (gold melting 1063°C, boiling point 2660°C, thickness 19320 kg/cm³);
Furnaces for melting srible (melting srible 960 ° C, boiling point 2180 ° C, thickness 10500 kg / cm³);
Pitch for steel melting (steel melting in furnaces 1450 - 1520 °C, thickness 7900 kg/m³);
Hall smelting pitches (cast smelting 1539°C, boiling point 2900°C, thickness 7850 kg/m3);
Furnaces for melting titanium alloys (melting titanium 1680°C, boiling point 3300°C, thickness 4505 kg/m³);
Pects for lead smelting (lead smelting in furnaces 327°C, boiling point 1750°C, thickness 1134 kg/cm³);
Brass smelting pects (brass smelting in furnaces 880-950 °C. thickness 8500 kg/m³);
Bronze melting furnaces (bronze melting in furnaces, 930-1140 ° C 8700 kg / m³).

Everything started from what I needed for ... everyone. I wanted to melt and fry the steel, and fire the hands, the new set, shorter. We'll forgive you with a path and fix the axis of such sal for 10k (+5k re-strength):

Proprate exactly two swimming trunks >_< после чего спираль потекла и попортила муфель:

Zagalom steal not raja, take stoves from the Chinese, breathe for one or two. However, I was far away to turn the varst, or standing on my beak. Ale without urahuvannya peresilki. Having spent 5,000 rubles on his hands, then he lost on his hands those things that were left in the oven, and himself: a graphite crucible, a purchase of firelighters, a thermocouple and a regulator, as well as fashionable tongs. Zreshtoy mayzhe nothing, singsong.

Pekti are dead, let them live again!
Qiu I have already chosen myself from the axis of which:
Fireclay cegla ShL - 1

The lightest fireclay is needed, so that in the new arc it is easy to cut the grooves under the spiral, and also the wines are also light (bright, from the other side). Narizaєmo in 4 rows of a furrow so that a spiral came out, which rises from the bottom uphill, to put the spiral into the qiu already another spiral from the fechral. I dug the bottom with such a bet, and also cut a couple of holes on the plugs in the furnace bunks. It is possible to glue everything in the field with a fireproof warehouse for laying fireplaces and stoves, fireproof sealant or fireproof adhesives.

Potim obov'yazkovo needs fechral, and more often superfechral. Nichrom not pidide, vіn vigoryaє pіd hour contact s repeat. I bought such a skein from Novosibirsk (do not give respect to those that lie to the beast):

Sell її on a wagon and here 3 kg, nursery opir 1.78 microohm per meter. Razrahunok necessitated power supply is even simpler: the square of the voltage is divided by the pressure (I demanded 1.5 kW) and the power of the opir. Tobto in my mind: 220 * 220/1500 = 32 ohms. 32/1.78 = 18 meters. At once we took 18 meters of dart and wound it on a bar of required diameter - it fit well into the furrows, propylene into the chains. Shvidko can be wound, for example, for the help of a screwdriver. I shook my hands %-)
The spiral will need to be stretched, so that the coils do not stick one by one and put it at the furrow

The easier it is to lay down the spiral at the furrow and kuti, the more it is - when heated, the fechral becomes softer and can sag and wiggle out of the hives. Zovni spiral to go out to the beast and from below (in the photo to the beast you can see the exit to the beast). Varto twist out of the air, so that there is not much grit. kіntsi middle wires I got out of the electronic remains of a Chinese oven. I can't pick out my own to take a picture of it, but the regulators are sold at the great radio parts stores. They look like this (levoruch):

In principle, it is already possible to turn on everything, for an idea, pratsyuvatime (for melting aluminum can be used). However, with more or less trivial victories, there will be great expenses and not to raise the temperature for melting midi, for example. In this case, multi-silica cotton wool is additional, so it’s just like ceramic fiber. Everything is sold in the online stores of the fireworks and is available for prices. Cotton wool costs about 200 rubles per kg. You need to wrap around the working chamber and start pozatikat all the holes with it, so that the heat does not go anywhere from the chamber. Kryshka for the idea of the best work again, but still with a light fireclay and cotton wool more and more tightly. - In short, build a yakomoga chamber more isolated from the outside world.

True, my hands do not reach the lid, so I just put the ceramic fiber in the Chinese oven in three balls at the top (at 1000 degrees in the middle, you can easily press the fiber to the beast with an unprotected hand).
Oh, so, forgetting things - mullite-silica cotton wool will seep out like an oily fool for ease of laying. When heated, it burns out and stinks noticeably;

Another thing - a thermocouple (a thermometer) is definitely not a trace of a beast, like mine. On the right, in that, in this position, there is a gap about the temperature, showing, in my mood, about 100 degrees lower, lower at the working area, where the blank is hanging in the photo.

Well, it’s great, go ahead, what a strum along the spiral. Before him, like climbing into the air, follow the vimikati of life, or show extreme caution, so as not to coil the spiral under the pressure.

shut down ×

On the vіdmіnu vіd promislovy obladnannya, samorobnaya pіch for melting metal - more compact fit. On such a portable device, it is possible to carry out melting, hardening or melting of colored metals.

Pekti for melting metal is a body, made from fireclay chains. The best element is clay. The firebox is recognized for the fire of the vugill. An opening is passed from below, through which air is blown in the heat. At the bottom, there is a chavun grate, as it is called a grate. On it, there is coke or vougillya. Yogo can be taken from the old stove. In some cases, the fire-fighting cegla, when molded to the body, is placed on the edge. The construction is ready to be creaked with a bell-shaped belt.

Pecti for remelting metal is the responsibility of the mother crucible. Tse mozhe buti enameling or chavunny cauldrons. The crucible was roztashuvannya - commissioned with coke to burn. With the method of repairing blowing, I ordered to install a fan. The property is zastosovuetsya for the melting of steel, but it is possible to vicorate like a pich for the melting of chavun.

Electric furnaces for melting metal

Asbestos becomes the basis of such a stove, which can be replaced with cough. Electrodes installed in the smelting furnace with their own hands are responsible for the mother's voltage 25 Art.

The stench is prepared in this order:

Vitochuyutsya from the shield of the electric motor.
Fence drilled open 6 mm.
The stench is passed through, with a 5 mm peretina.
Flowers are driven in to secure the wiring.
With the method of polypshennia contact with graphite, sawing the nasіchki.

Like an insulator, mica is laid in the middle of the oven. When connected to a wire, it is necessary to switch the transformer, which will be lowered. After preparation, it will start to work for the next hour in idle mode.

Muffle pich

Muffle furnaces are often vicorous for heat treatment of parts. This property is characterized by a large temperature range from 20 to 1000 degrees.

Muffle pіch for hardening metal pracyuє on different types energy. However, at home minds, it is better to stop the unit, which works on electricity. Hardening is carried out in a muffle furnace.

Muffle pіch with their own hands is prepared for a sprat of stages:

The preparation of the muffle is carried out from a fireclay chain. Across round shape kiln bodies, they have sloping kuti. Grooves are vibrated at the skin celin, where the helix is laid.
If a muffle furnace for melting is prepared from the oven, then in the middle it is lined with a fire core. At the hoard, grooves for the spiral are cut through.
A chamber was prepared from a fire-fighting unit, which is placed in the body, shattered from steel. Insulation is laid at the bottom. The gap between the side walls of the chamber and the body should be 4 cm, where the insulation is inserted. The top is folded with 2 balls of metal and insulation.
Openings are drilled at the body, and through them the ends of the spirals are led out, as if they are connected to the wire cable.
At the time of the vikoristanny of the oven, the heater is not needed. Vin has already been transferred.

Aluminum melting

Prepare a fuel for melting aluminum with your own hands is real rich. The industrial production of aggregates with the name - carousel type furnaces - is more expensive.

In order to understand, how to develop a fuel for melting aluminium, it is necessary to understand the principle of science. Іsnuє kіlka vidіv, where the melting of color metal is carried out.

Mini-pecti

Take a car disk and bury it in the ground so that the upper gap does not speak its name. In the middle there is an opening for the branch pipe. One end is skipped in the opening, and the other one is shown by name. A cooler is put on the new one for pumping air. The smelter is filled with coals and aluminum bruch. The temperature is raised again.

metal tank

You can prepare food for aluminum from a metal tank. For example, cases cleaning machines with vertical vanishing. The internal part of the structure is lined with a whole fire pit. From the bottom, a supply pipe is mounted again. In this rank, it is portable to come out.

3 dances

One of the unimaginable methods by which aluminum is melted. Navkoly dances are wound with dry nichrome. The front surface of the dance is smeared with olive. A sum of a rare layer of clay is applied on top. Drying is carried out by stretching. Let's wind up a ball of dart and apply clay. After 7 days, the puff is wrinkled and only the heat-resistant shell is left. Before the end of the dart, a voltage is connected to roast the nichrome, and in the middle, the syrovin is zavantazhuetsya.

Lead smelting

The electric furnace for melting lead is composed of the following elements:

Round casing, made of stainless steel, with insulation in the middle. Vіn attachments with brackets to the wall.
From the bottom, the words of TEN are given.
At the top there is a swivel type valve.
The sensor, which is located at 3 cm from the bottom.
On the side of the rotting is a temperature regulator.

Installing the regulator to the right temperature, the attachment is warming up. Lead, which is in the middle, melts. At the end of the melting, a form is brought to the bottom and a valve is opened. The melting of lead fills the inner space of the mold.

Swimming midi

At home minds for melting midi, you can beat the material foam concrete. There are 2 cylinders with a diameter of 100 mm for this material. The height of one is 100 mm, and the other is 15. Putting one on the other, drill in the middle of the hole with a diameter of 15 mm. At the large cylinder in the middle, an opening is made at the sight of a virvi on a depth of 85 mm. In the middle of the cylinder, from the outer side, a groove is cut and tightened with a dart. It is necessary to ensure that the part does not fall apart due to temperature.

On the gas stove an adapter is installed. A larger cylinder is rolled up at the top so that the conical virva is straight uphill. The top is curved with a small cylinder from the lapel. Lighting the palnik, lower the piece of the mid-length hair into a small opening until it stops against the wall of the virvy. For the whilina, the sheared will melt.

Melting gold that sribla

Pects for melting gold are easy to make in household minds. Vaughn zastosovna th at the smelting srіbla.

The order of robotic advances:

Fireclay chain is taken and cut into 2 parts. Let's use a drill with a diameter of 48 mm, vibrate in one half, in the middle, open the hole. And in the other, the hole is drilled to half the height.
A spiral is passed through the opening and the offending halves are tightened with bolts, open for them to be drilled from the sides.
A graphite crucible is installed at the top.
A metal frame is being prepared and the trimming halves are inserted up to the new one.
Usі bіchnі gaps are smeared with clay.
Before the introduction of the endings, the spiral is put under pressure.
At the crucible, small pieces of gold chi srіbla are thrown.
In the process of heating to melt the colored metal.

Do-it-yourself preparation of furnaces for melting metal with your own hands, the process of folding, ale zdijsnenny. For whom it is necessary to maintain the power of the species of possession. Designate them as the most important to these minds. Vitrati prepared quickly to recoup yourself.
