The difference between medium frequency induction heating equipment and high frequency induction heating equipment

1. Different frequencies of use: We usually call induction heating equipment with a frequency of 1-10Khz as medium-frequency induction heating equipment, and induction heating equipment with a frequency above 50Khz as high-frequency induction heating equipment.

2. Affected by the frequency of induction heating equipment, the quenching depth of the two is also different. The quenching depth of medium frequency induction heating equipment is generally 3.5-6mm, while that of high-frequency induction heating equipment is 1.2-1.5mm.

3.Different diathermy diameters: The medium frequency induction heating equipment has great advantages in the diathermy of the workpiece. It is mainly used for diathermy heat treatment of the workpiece. It can perform diathermy heat treatment on the workpiece with a diameter of 45-90mm. The high-frequency induction heating equipment can only heat those thin and small workpieces.
