What are the losses in the melting process of the induction melting furnace?

In the melting process of the induction melting furnace, electric energy is converted into heat energy through electromagnetic induction, and then steel is melted through heat energy. In this energy conversion process, there are mainly the following energy losses:

(1) The energy consumption of the electromagnetic coil itself is called copper consumption. To

(2) The heat loss on the furnace body in the process of converting electrical energy into thermal energy is called furnace consumption. To

(3) The heat radiation generated when charging, melting and discharging at the furnace mouth is called radiation loss. To

(4) Power distribution equipment also loses energy in the process of electric energy transmission, which we call additional loss.
