Thirty Tons Medium Frequency Induction Melting Furnace - China

1 - Description of 30 tons of molten steel furnace

30 tons of molten steel furnace: including pulse rectifier transformer, a frequency power supply, two sets of steel melting furnace and auxiliary PLC management systems and other components.

The PLC-assisted smelting management system not only displays the real-time data and information of the power supply operation, but also displays the operating status and information of the entire system, and has automatic oven, cold furnace start, fault diagnosis, fault information display and storage, and operation information display., system status display and other functions.

Basic configuration: 24-pulse rectifier transformer (rated capacity 15000KVA), two sets of steel furnace, a frequency power supply, a set of inverters compensation capacitor structure 12 with power supply 24 double pulserectifier inverter parallel structure.

The tilting method is hydraulically reversed with a remote control box.
