The induction furnace body is composed of a coil and a furnace inside the coil. When the AC power is input to the induction coil, an alternating magnetic flux can be generated in the furnace. When they pass through the heated metal, the induction is generated in the metal due to electromagnetic induction. The "eddy current" of the current, which is the work of the metal itself, transforms the electrical energy into heat to heat the workpiece.

The copper ingot induction heating furnace should be a device for heating the copper ingot by an induction furnace.
