What issues should be paid attention to when the induction melting furnace starts melting?

electric melting furnace

①During the melting process, the capacitance should be adjusted continuously to maintain a high power factor. After the charge is fully melted, the molten steel is superheated to a certain degree, and then the input power is reduced according to the smelting requirements.

②The melting time should be controlled appropriately. If the melting time is too short, it will cause difficulties in selecting voltage and capacitance, while if it is too long, it will increase unnecessary heat loss.
