Elements for selecting the frequency of high-frequency quenching equipment

1. The frequency conversion power supply is the energy basis for realizing the rapid heat treatment of steel induction heating. The frequency of the power supply plays an important role in the induction heating process and is the most important technical basis for the selection of induction heating equipment.

2. The power frequency is directly related to the electrical efficiency, thermal efficiency, heating speed and uniformity of heating temperature in the induction heating process. At the same time, the choice of power frequency also involves economic indicators such as equipment investment costs and production costs. Therefore, the selection of power frequency is a complex and comprehensive work.

3. The electromagnetic conversion of the induction heating system is more complicated, and the total efficiency of the system is difficult to obtain. Usually the efficiency of the inductor is used as the basis for selecting the power frequency. For this reason, the highest heating efficiency of the inductor is the target for selecting the power frequency.
