Steel Metal Copper Melting Scrap Induction Smelting Melting Furnace

Welded by section steel, its rotary bearing hole and tilting cylinder bearing hole are processed once by a large boring machine, which ensures the concentricity, so that the shell and rotary shaft will not be deformed due to different concentricity in the tilting process.

This set of equipment adopts thyristor fully controlled rectifier bridge. In series resonant power supply, the rectifier thyristor always works in a fully open working state under any circumstances, so that the output of DC voltage is stable, and the power factor and harmonic content are not reduced. When the power supply fails or alarms, the thyristor fully controlled rectifier bridge is equivalent to a solid-state control switch, which will cut off the main circuit immediately and protect the main components of the power supply most effectively.
In the inverting trigger part of the circuit, a special swept-frequency zero-voltage soft-start is adopted. Only one intermediate-frequency current feedback signal is needed, which is essentially equivalent to its self-excitation circuit and belongs to the average feedback circuit. Because there is no need to add any starting circuit to the main circuit and no need to pre-charge or pre-charge the starting process, the main circuit is simplified and the debugging process is simple.
