How to correctly choose the heating frequency of the induction heating furnace to achieve the effect of energy saving?

It is very important to correctly select the heating frequency of the induction heating furnace, because it will directly affect the thermal efficiency of the induction furnace and the heating efficiency of the blank. If the selected current frequency is too high, the heating time will be prolonged, the heat loss will increase, the thermal efficiency will decrease, and the heating efficiency will also decrease, resulting in an increase in the cost of the frequency conversion setting.
