1. Determine the frequency at which the current penetrates the depth of the power supply current in the material to be heated: the greater the ratio between the layer thickness δ to be heated and the current penetration depth p, the smaller the height of the inductor should be;

2. Input the unit power P of the heated surface per square centimeter. The distribution of temperature along the cross section and the surface of the heated area is related to the value of P;

3. The shape and thickness of the area to be heated and its position on the workpiece to be treated, which determines whether the sensor is likely to be accessible and placed (referring to heating the outer or inner surface, grooves, flanges and the like) In the case of).

     When designing the inductor, not only should the technical problems of the heating zone be addressed, but also the cost of the fixture should be considered low, the process is simple, and the use is convenient.
