Electric furnace steelmaking​ mainly uses arc heat. In the arc action zone, the temperature is as high as 4000 °C. The smelting process is generally divided into a melting period, an oxidation period and a reduction period. In the furnace, not only an oxidizing atmosphere but also a reducing atmosphere can be created, so the efficiency of dephosphorization and desulfurization is very high.

Since the principle of medium frequency induction heating is electromagnetic induction, and its heat is generated in the workpiece itself, ordinary workers can carry out continuous work of forging task ten minutes after working with medium frequency electric furnace, and there is no need for professional workers to burn and seal the furnace in advance. There is no need to worry about the waste of heated blanks in the coal furnace caused by power failure or equipment failure.

Induction furnace is an electric furnace that uses the induction electric heating effect of materials to heat or melt materials. The main components of induction furnace include inductor, furnace body, power supply, capacitor and control system.
