Blister electromechanical heating induction heating

The conductor itself is heated by the thermal effect formed by the induced current (eddy current) generated by the conductor in the alternating electromagnetic field. According to different heating process requirements, the frequency of AC power supply used in induction heating includes power frequency (50-60 Hz), intermediate frequency (60-10000 Hz) and high frequency (higher than 10000 Hz). The power frequency power supply is the AC power supply usually used in industry. The power frequency of most countries in the world is 50 Hz. The voltage applied to the induction device by the power frequency power supply for induction heating must be adjustable. According to the power of the heating equipment and the capacity of the power supply network, a high-voltage power supply (6-10 kV) can be used to supply power through a transformer; the heating equipment can also be directly connected to a 380-volt low-voltage power grid. The intermediate frequency power supply has used the intermediate frequency generator set for a long time. It consists of an intermediate frequency generator and a driving asynchronous motor.
