The major advantages:
1. Saving-energy and high efficiency: It consumes electricity 320KWh when heating one M-ton steel each time. It saves electricity 20%-30% more than SCR medium-frequency power supply.
2. Medium-frequency heating has good heating effect: Much easier throughout heating, evener, quicker, and less oxides.
3. The heating length, speed, and temperature of part can be accurately controlled.
4. It won¡¯t cause electromagnetic pollution outside around the equipment. Supply transformer won¡¯t generate heat, electrical substation compensation capacitor won¡¯t generate heat, and it won¡¯t interference other equipments working.
5. It is automatically controlled and has kinds of protection: It is set up with alerting indication of overvoltage, excess current¡¢overheating¡¢lack of water.
