[0002] The high-frequency heating device is currently the most efficient, fastest, low-consumption, energy-saving and environmentally friendly induction heating device for heating metal materials. When the high-frequency heating device is used, the workpiece is inserted into the high-frequency coil and a high-frequency current is passed through the coil. The high-frequency current flows through the coil to generate an alternating magnetic field, which causes the workpiece to generate eddy currents for heating.
