The principle of high frequency induction heating machine
It is a heating induction coil that is wound into a ring state or a desired shape by using a large current that emits high-frequency waves. High-frequency induction is usually made of copper hollow tubes. A strong magnetic beam with instantaneous change of polarity is generated in the high-frequency induction coil, and the metal to be heat-treated is placed in the high-frequency coil, and the magnetic beam will penetrate the entire heated metal object. In the interior of the induction heating object, a corresponding strong eddy current is generated in the opposite direction to the induction heating current. Because there is resistance in the induction heating metal, strong Joule heat energy is generated, so that the temperature of the induction heating object rises rapidly, so as to achieve the purpose of heat treatment. Therefore, in the industry, high-frequency induction heating machines can also be called: high-frequency induction heating equipment; high-frequency induction quenching equipment; induction diathermy equipment; high-frequency quenching machines, high-frequency induction heating machines, and high-frequency welding machines.
