Frequency selection should follow the following principles: 1) the heated of magnetic materials (such as the iron, carbon steel, etc.) should be common frequency is low, and the magnetic materials (such as stainless steel, copper, aluminum, etc.) should be higher frequency. 2) the magnetic materials, the heating temperature not more than Curie point (magnetism loss point) frequency should be lower, more than Curie point, high frequency should adopt different frequency (section). 3) the more close to the cylinder, the easier it is heating, low frequency is. Conversely, special-shaped cross-section frequency should be higher. 4) heating section workpiece, the outer area surrounded by eddy current, the greater the frequency should be more low, vice is higher. 5) the heated parts if can put in tubular or ring sensors, heating efficiency high, internal frequency is lower. If only on flat beside sensors, heating efficiency, low frequency should be higher. Power choose the following factor should consider: 1) the workpiece material (specific heat, magnetic, electric properties); performance 2) the effective heating area workpiece quality; 3) the heating temperature (temperature) 4) heating speed; 5) the shape; 6) insulation performance.
