Ultra-High Power Electric Arc Furnace

Application:

For smelting carbon steel, high quality carbon steel and various alloy steel. It applies to all steel scrap, hot metal crap, pelletizing and preheating steel scrap, hot briquetted iron and sponge iron, etc.

 

Features of the equipment:

Series reactor in main loop improves the system impedance and achieves secondary high-voltage, long-arc and low-current operation with stable arc and high arc power. On-load tap changer is adopted during the operation of the EAF, which comprises left or right operation, rotating lid, top charging and eccentric bottom tapping. The furnace body is of frame-type full water-cooling structure, with detachable upper and lower furnace shells, concentric circular tubular furnace cover in the water-cooling structure, Oxygen lance at the furnace door and burner on the furnace wall. The proportional valve controls electrode lifting, rotation of furnace cover and furnace tilting. There are a whole set of PLC, and computer control system and computer screen monitoring system.

It consists of: Furnace body, furnace tilting mechanism, electrode lifting mechanism, furnace cover lifting and revolving mechanism, cooling water and its display & alarm mechanism, hydraulic unit, compressed air system, charging system, high-pressure switching system, transformer, series reactor, low-voltage power supply system, computer control system and screen monitoring system.
