1. The use frequency is different: we usually call the induction heating equipment with the frequency of 1-10khz as the medium frequency induction heating equipment, and the induction heating equipment with the frequency of more than 50KHz as the 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: medium frequency induction heating equipment has great advantages in the diathermy of workpieces. It is mainly used for diathermy treatment of workpieces. It can diathermy treat workpieces with a diameter of 45-90mm, while high frequency induction heating equipment can only diathermy those fine and small workpieces.
To sum up, the heating methods of medium frequency induction heating equipment and high frequency induction heating equipment are the same, but the frequency is different. Their use frequency is not painful, so they are also different in terms of price and processed workpieces. Therefore, when heating workpieces, we should choose our own induction heating equipment.
