Electric Arc Furnace (AC)

HH Series AC Electric Arc Furnaces Applications HH series steelmaking AC arc furnaces are used for melting quality carbon and alloysteel, their normal capacities are from 0.5t to 125t. Features In HH series furnaces, OP, HP and UHP power input models arc available, both right and left operations for your choice. Roof swinging and top charging. Advanced designs of the furnaces ensure operation reliable and performance excellent. Descriptions ·Furnace body Tapping manners: spout and EBT. Tubular water-cooled and traditional foof are available. ·Tilting mechanism. ·Electrode lifting mechanism It can be realized by bogie movement or mast lifting, common copper tube arm or advanced water-cooled conducting arm are available. ·Roof lifting and swinging mechanism. Integrated or separated foundation designs for your choice. ·Cooling-water monitoring and alarming system. ·Hydraulic station and control valves system. ·Electric control system: Automatic regulator of electrode lifting can be VVVF controlled or computer controlled. The later can equipped with CPT displayer. The acting of all parts and interlocks is controlled by PLC.
