The principle of medium frequency induction heating: when an alternating current is passed into a coil, a corresponding alternating magnetic field is generated in the coil, that is, an alternating magnetic flux whose size and direction change with time. When a piece of conductive metal is placed in a coil, according to the law of electromagnetic induction, a current is generated in the metal. This current is called an induced current or eddy current. The coil is called an induction coil or inductor. The magnetic flux generated by this eddy current is always trying to prevent The magnetic flux within the coil changes. If the alternating current applied to the coil does not stop, the eddy current in the metal cup will not stop, and the eddy current in the metal will not stop. As we all know, any metal has resistance. According to Joule-Lenz's law, eddy current flowing in a metal with a certain resistance will generate heat, thus heating the metal cup or even melting it. This is the so-called induction heating.
Medium frequency induction heating equipment improves product quality, saves energy, reduces production costs in diathermic forging, further optimizes the forging process, and realizes mechanized and automated production. Medium frequency induction heating equipment has gradually been widely used in diathermic forging.
