1. Function of Steel Shell Induction Melting Furnace:
Intermediate Frequency Electrical Melting Furnace, also called as Induction Smelting Furnace, which converting three phase power current into single phase intermediate frequency current and enabling metal to produce eddy current loss through electromagnetic field induction to achieve heating and melting.
It is applicable to melting, heating or insulting of steel, copper, iron, aluminum, zinc, tin, nickel silver and other ferrous, nonferrous metal. It can also be used for other heating treatment before forging, sintering and tube-bending forming in the casting and melting industries.

3. Feature of Steel Shell Induction Melting Furnace:
According to the theoretical calculation and field test, it can save half of the transformer capacity.Because of adopting SCR series rectifier , series resonant inverter it is with high power factor and keeps over 0.98 with high order harmonic wave pollution.It is no need to add reactive power compensation device and harmonic wave control device.The current of induction coils are small and the melting time is short.It can save electricity 20%.
Rugged and elegant, especially for large-capacity furnaces, it requires a strong rigid structure. From the safety point of the tilting furnace, try to use steel shell furnace.
The presence of the furnace cover reduces heat loss and increases the safety of the equipment.
