How to choose the current frequency of the 感應加熱爐?

To correctly select the current frequency of the induction heating furnace according to the diameter or thickness of the heated workpiece is the fundamental guarantee to improve the heating efficiency of the induction heating furnace. The ratio of the diameter (or thickness) of the workpiece to the penetration depth of the current determines the electrical efficiency of the induction heating furnace. Generally speaking, the heating frequency of the induction heating furnace is low when the diameter of the workpiece is large; the heating frequency of the induction heating furnace is high when the diameter of the workpiece is small; the selection of the current frequency of the induction heating furnace is not good, which will greatly affect the heating efficiency of the induction heating furnace and reduce the induction heating rate. Heating efficiency of the furnace.
