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

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

1) High frequency is suitable for quenching or welding, high frequency, heating from the outside to the inside, applied to surface heat treatment equipment.

2) Medium frequency is suitable for forging dithermic, low frequency, heating from inside to outside, more uniform dithermic.

3) The choice of medium frequency heating or high frequency heating method should be based on the product design requirements, temperature control is determined by reasonable process parameters, there is no better, the key is whether to meet the product requirements.

Intermediate frequency: The frequency range is generally about 1kHz to 20kHz, and the typical value is about 8kHz. Heating thickness about 3-10mm. It is widely used for heating, annealing, tempering, tempering and surface quenching of large workpieces, large-diameter shafts, large-diameter thick-wall pipes, large-modulus gears and small-diameter bar red stamping, forging and so on. High frequency: The frequency range is generally 40kHz to about 200kHz, and 40kHz to 80kHz is commonly used. Heating depth or thickness of about 1-2mm. It is widely used for deep heating, brazing, red blanking, forging annealing, tempering, tempering, surface quenching, medium diameter pipe heating and welding, hot assembly, pinion quenching and so on.
