The main working principle of high frequency heating machine
Basic principle: The high-frequency heating machine puts the workpiece into the inductor (coil). When an alternating current of a certain frequency is passed into the inductor, an alternating magnetic field is generated around it. The electromagnetic induction of the alternating magnetic field produces a closed induced current (eddy current) in the workpiece.
At present, the high-frequency heating machine has the highest heating efficiency, fastest speed, low consumption and environmental protection for metal materials. It has been widely used in various fields of hot processing, heat treatment, hot assembly and welding, smelting and other processes of metal materials. It can not only heat the workpiece as a whole, but also purposefully heat the part of the steel; it can achieve deep heat penetration of the workpiece, and it can only heat the surface and surface of the workpiece; it can not only heat the metal material directly, but also heat Non-metallic materials for indirect heating, etc.
