The induction coil is the heart of the whole induction furnace. The induction coil is powered by the intermediate frequency power supply. Under the action of the intermediate frequency voltage and current, a strong magnetic field is generated. This magnetic field causes the metal in the furnace to generate eddy current and heat. The coil is the key to the thermal energy conversion. Therefore, the coil design is very important. The coil of the electric furnace is a better solution determined by the computer analysis and calculation according to the principle of electromagnetic field in combination with the actual use condition of the intermediate frequency furnace at home and abroad.
