Heating process of bar induction heating furnace

1. First, the intermediate frequency power supply of the bar प्रेरण हीटिंग फर्नेस generates a variable frequency current, and the variable frequency current flows through the induced current generated by the induction coil, and the induced current flows in the bar material, overcoming the resistance of the bar material to generate heat, thereby converting electrical energy into heat energy Realize the heating of metal bars.

2. Secondly, when the alternating current of the bar induction heating furnace passes through the induction coil, an alternating magnetic field that is synchronized with the current is generated in and around the induction coil. When the magnetic field lines of the alternating magnetic field pass through the metal bar and are cut, an eddy current will be formed inside the metal bar. The strength of this magnetic field depends on the strength of the current passing through the induction coil, its frequency, the number of coil turns, and its geometry.
