The principle of high-frequency induction heating equipment is that the dielectric material undergoes molecular polarization under the action of high-frequency electric field, and is arranged in the direction of the electric field. Because the high-frequency electric field changes the molecular direction at a very fast speed, the dielectric material will Loss and heats up.

The high-frequency current flows to the heating coil (usually made of copper tube) that is wound into a ring or other shape. As a result, a strong magnetic beam with an instantaneous change in polarity is generated in the coil. When the heated material such as metal is placed in the coil, the magnetic beam will penetrate the entire heated material, and a large vortex will be generated inside the heated material in the opposite direction to the heating current. Electric current generates Joule heat due to the resistance in the heated material, so that the temperature of the material itself rises rapidly, which is the principle of high-frequency induction heating.
