Correctly select the current density of the induction coil to achieve the purpose of energy saving

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.
