The difference between high frequency and ultra audio frequency of induction heating equipment

What is the specific difference between the ultrasonic induction heating equipment  and the high-frequency induction heating equipment? The first is the most typical surface oscillation frequency of the equipment. If the oscillation frequency of high-frequency induction heating is quenching, the hardening layer is 0.5~1.5mm, which is suitable for small and medium-sized parts requiring a thin hardening layer, such as small module gears, small and medium-sized shafts, etc; The oscillation frequency of ultrasonic induction heating is 30~36khz, and the hardening layer is 1.5~3mm. The hardening layer can be distributed along the contour of the workpiece. It is suitable for the surface heat treatment of small and medium module gears with moderate hardening layer.


In terms of power consumption, high-frequency induction heating equipment has a high oscillation frequency, which consumes a little more power than ultra audio, so it will be more expensive in terms of price. This is the difference between high-frequency induction heating equipment and ultra audio, but most customers can’t distinguish between high-frequency and ultra audio. To some extent, ultra audio can also be called high-frequency, but you don’t have to worry. Each induction heat treatment equipment manufacturer has professional technicians to explain it to you, Recommend appropriate equipment for you. Of course, you can also call Hebei FOREVER electromechanical Co., Ltd.


Whether it is high frequency or ultra audio, they all have some common characteristics:
