摘要
The superconducting induction heating device can be used to heat the rotating metal workpieces in its DC magnetic field. It has higher efficiency than traditional AC induction heating device and has a greater market competitive advantage. In this paper, a double C-type device is proposed based on the existing heating device, which greatly reduces the use of ferromagnetic materials. By studying the influence of air gap magnetic field distribution on the eddy current loss, a method based on arc air gap is proposed to improve the heating efficiency. An equivalent model is established to analyze the starting torque of the DC induction heating device, and the variation rules of the starting torque with the rotation speed and the workpiece radius are obtained. According to the special structure of the double coils and double iron cores of the device, a variable air gap method is adopted to solve the problem of excessive starting torque in the heating process. The relevant research conclusions can provide a reference for the design of superconducting DC induction heating device with iron-cores. © 2021, Electrical Technology Press Co. Ltd.
