Electric Induction Melting Furnace

electric induction melting furnace

As metal smelting equipment, an electric induction melting furnace is a relatively advanced and economical smelting equipment. In metal processing, many metallurgical enterprises are using medium-frequency induction furnaces. Now let’s know what the working principle of an electric induction heating furnace is and what the characteristics of an intermediate frequency smelting furnaces are. What is its use or function?

Working Principle of Electric Induction Melting Furnace

The electric induction melting furnace is mainly composed of a power supply, induction ring, and crucible made of refractory materials in the induction ring. The crucible contains a metal furnace charge, which is equivalent to the auxiliary winding of the transformer. When the induction coil is connected to the AC power supply, an alternating magnetic field will be generated in the induction coil, and its magnetic line of force will cut the metal charge in the crucible, and an induced electromotive force will be generated in the charge.

As the furnace charge itself forms a closed loop, this secondary winding is characterized by only one turn and is closed, so the induction current is generated in the furnace charge at the same time. When the induced current passes through the furnace charge, the furnace charge is heated to promote its melting. The electrical induction melting furnace uses the medium-frequency power supply to establish the medium-frequency magnetic field, so that the ferromagnetic materials can generate induced eddy currents and heat up, so as to achieve the purpose of heating materials.
