Electrical furnace

Electrical furnace is a furnace that generates heat. Electrical furnace requires electrical supply because this furnace is completely dependent on the electrical supply. Without electrical supply, this electrical furnace cannot work because in such a furnace. Electrical element is required when using electron key coil in this furnace, when the electron coil is connected to the electrical supply then heat is generated in it, in which use heating element is mainly used for the winding coil inside the electrical furnace. It is used or the length of the wire of the coil is more the value of resistance is greater in the wire from which the coil heat is generated, the element used is 80% Nichrome, 80% alloy or 20%. Chromium is used mainly in many types of electrical furnace.

electrical furnace Arc types furnace : -


Arc types furnace is used to generate heat when the heat rises, the metal that is kept in it melts or the inaccuracies in the metal after melting are separated as slag or the metal left after it It is completely pure or arc types use electrical supply in furnace, arc types can use carbon electron in furnace or it can use graphite electron. This type of furnace is made of outside steel. It can use acid lining inside or m You can use agnetite,

it has a door to insert the row material from which the row material is inserted when the electron of carbon is given electrical supply electrons produce arc. It is produced between the arc metal or electron. There is a gap between the two, due to arc production, heat will be generated in the furnace due to which the metal placed in the furnace is melted, causing the inaccuracies from the metal to rise up and form a layer called slag, arc furnace temperature 2000  0C Reaches

The slag layer in it is taken out separately and after that the metal is also put in a separate container, so we can take high quality steel, inside it we can also make allow steel, it is very simple to use arc types furnace

DC Arc Furnace : -


This furnace also comes in arc types furnace DC arc furnace is mainly used for steel production. A transformer and rectifier come together for operation or use of dc arc furnace. Complete installation of dc arc furnace is done through ABB company.

 ABB company is mainly famous in the world of about 130 year dc arc furnace. And many costumer are using dc arc furnace. DC arc furnace is used to melt scrap metal, dc arc furnace's controlling system is very good which benefits the customer. Its use is important application in ferroalloys metal production; Its alloys are silicon metal, ferrosilicon, and ferromanganese. They allow the insertion of a tap changer to increase-decrease the voltage in this DC furnace. This operation works together with the dc arc furnace thyristor rectifier and large smoothing choke. DC arc furnace transformer was designed in 1885.

electrical furnace Induction  types furnace : -


An induction furnace is an electrical furnace that is applied by the induction temperature of the metal. The capacity of induction furnace is less than one kG to one hundred tons, and it is used for melting iron and steel, copper, aluminum and precious metals.

The advantage of induction furnace is a clean, energy-efficient and easy to control electrical furnace compared to metal melting and other means.

This type of furnace is more commonly used in modern castings, and now copal induction furnace is used along with induction furnace to melt iron, as a lot of dusted other pollutants come out in the former site.

Because no longer use an arc or coal furnace, the temperature of the induction furnace is high enough to melt any iron or steel; Because the loss of valuable alloys from the induction furnace can be prevented.

The use of induction furnace in a factory does not have to pay a huge price once installation of induction furnace is charged. The charge material should be clean in oxidation products and structure.

Induction furnace works on the principle of electromagnetic induction. They are divided on the basis of their frequency (50 hz - 250 khz).

1. high frequency induction furnace

2. medium frequency induction furnace

3. low frequency induction furnace

Advantage of induction furnace: -


1. induction furnace me no arc is generated so there is no honey in working

2. It does not put a bad flow on the environment

3. It can be easily controlled

4. Operator working on induction furnace can easily control it

Types of Induction furnace: -


1. Channel type furnace

2. Coreless type furnace

 Channel type furnace: -


The channel type furnace is basically a pot induction furnace with one or more inductors connected . Exactly the way secondary winding  is used with the help of a metal loop in the transformer.

 In this furnace, energy is replaced by a power system.

The line frequency is converted into heat through an electricity supply to the inductor. An Advantage of the Types

Channel types furnace means that it is made in a pot shape that suits the application,

disadvange are like this -

1. power input limit per inductor.

Coreless type furnace: -


This coreless furnace (shape) is designed like a cylindrical screwball, it has an energy coil which contains energy. In such types of furnace, a direct supply is given through a line or frequency converter.

The magnetic field that generates energy through coil leads to graze. To protect the furnace of these types from overheating, the coil is cooled through water, and the water is collected again. And the water cools down

Coreless furnace is commonly used for melts of all types of iron and steel. Or many people allow alloys. Use to melt

Electrical furnace Resistance furnace : -


Resistance furnace comes in an electrical furnace. Resistance furnace can provide ac supply or Dc supply to electricity supply of both types. Resistance In furnace, heat is generated with the help of Resistance in which the electron rod used, the value of Resistance is high or.

It can be said that a large amount of resistance is found in it, with the help of which heat is produced. His

Temperature upto about 1000 0C can be obtained with the help of Resistance Heat


Electrical furnace


Types of Resistance furnace: -


1. Direct Resistance furnace

2. Indirect Resistance furnace

Direct Resistance furnace: -


Two electron plates are used inside the Direct Resistance furnace, the amount of Resistance is found more inside the electron plate, there is a carbon, nichome, powder of powder inside the direct resistance furnace, which can be made by adding it to the Direct Resistance furnace. Then when the electron plate is connected to the  ac/dc supply, heat is generated due to i2R copper loss in the electron plate. High resistance powder is inserted to protect the electron from the plate short circuit. The job of the powder is to protect the electron plate from having a short circuit.

Application of Resistance furnace: -


1. Dry and baking of potteries

2. annealing, hardening

3. Domestic and commercial cooking
