IGBT Shaft high frequency Induction Quenching hardening Machine for
heating treatment
1. Working principle of medium frequency induction heating
equipment:
High-frequency high-frequency high 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 a
heated object such as a metal is placed in the coil, the magnetic
beam will penetrate the entire heated object, and in the opposite
direction of the heating current inside the heated object, it will
generate Correspondingly large eddy currents. Due to the existence
of resistance in the heated object, a lot of Joule heat will be
generated, and the temperature of the object itself will rise
rapidly. To achieve the purpose of heating all metal materials.
