When the current of the inductor of the induction heating furnace is constant, the cross-sectional size of the pure copper tube of the induction coil should be selected to control the current density within a certain range. The current density increases, the power loss of the induction coil increases, and the electrical efficiency of the inductor decreases. Of course, the cross-sectional size of the pure copper tube of the induction coil is also determined by the number of turns of the induction coil and the geometric size of the inductor.
