Induction Furnace Oven - Melting Furnace

Induction furnace oven is an electric furnace that works on the principle of releasing heat by inductively heating metal. The induction furnace capacity varies from 1kg to 100t. Can be used to smelt steel, copper, aluminum and precious metals. Smelting furnaces of different specifications smelt corresponding metal materials.

Advantage

1. Compared with most other metal melting methods, the advantages of induction furnace oven are cleanliness, energy saving and well-controlled melting process.

2. Most modern foundries use this type of furnace. Many iron foundries are melting cast iron with induction furnaces instead of cupola furnaces, which emit large amounts of dust and other pollutants.

3. Induction furnaces do not require electric arcs (such as electric arc furnaces) or fuels (such as blast furnaces).

4. The charge (the material that goes into the furnace to heat it, not to be confused with the electric charge) is never hotter than it needs to be to melt it; this prevents the loss of valuable alloying elements.

Shortcoming:

A major disadvantage of using induction furnaces in foundries is their lack of refining capacity: the charge must be free of oxides and of known composition, and some alloying elements may be lost to oxidation and must therefore be re-added to melt.

Working Principle

In an induction furnace oven, there is an induction coil that creates an alternating magnetic field when an alternating current is passed through it. Place the metal charge that needs to be heated and smelted in an alternating magnetic field, and through electromagnetic induction, an electric current is generated in the metal charge. 

Due to the resistance of the metal charge, the metal charge will be heated when the current passes through it. The induction furnace mainly uses this heat to heat and melt the metal charge.

Therefore, the two basic conditions for induction heating are:

1. Use alternating current;

2. The object to be heated must be a metal material.

Use

1. Heat treatment: partial or overall quenching, annealing, tempering and diathermy of various metals;

2. Thermoforming: whole piece forging, partial forging, hot heading, hot rolling;

3. Welding: brazing of various metal products, welding of various knife blades and saw blades, welding of steel pipes and copper pipes, welding of the same and different metals;

4. Metal smelting: (vacuum) smelting, casting molding and evaporation coating of gold, silver, copper, iron, aluminum and other metals;

5. Other applications of high-frequency heating machine: semiconductor single crystal growth, thermal fit, bottle mouth heat sealing, toothpaste skin heat sealing, powder coating, metal implanted plastic, etc.

Generally, the electric induction furnace produced and supplied by HANI METALLURGY is mainly used for heat treatment, metal melting and so on.
