1. Overview
The electric arc furnace adopts ordinary power, top loading with unscrewing furnace cover, and the
tapping channel to tap steel. The structure adopts semi-hydraulic and furnace cover unscrewing type.
The pit-type layout can reduce the requirements for the height of the factory building.
2. Main features of the electric arc furnace
This electric arc furnace for steel making adopts basic furnace lining or acidic furnace lining for smelting oxides,
precious metal enrichment and other varieties.
This electric arc furnace equipment has the following main features:
▲ The electric arc furnace equipment is set with unscrewing furnace cover, top-loading, semi-hydraulic mechanism,
tapping through the tapping chute, and installation in the pit.
▲ Using copper tube type conductive cross arm.
▲ Use large cross-section water-cooled cables.
▲ Adopt integral furnace shell structure.
▲ The bottom of the electric arc furnace adopts a dish-shaped structure, which improves the reliability of the equipment
and prolongs the service life.
▲ The furnace cover rotation adopts the large turntable technology, which reduces the displacement of the water-cooled cable, reduces the impedance, reduces the electric loss, reduces the power consumption, and reduces the occupied area.
▲ The most advanced PLC electrode regulator is used to ensure the accuracy and reliability of the electrode
system to the greatest extent.
▲ The electrode lifting circuit is equipped to prevent the electrode from breaking and ensure the efficient operation of the furnace.
▲ The voltage regulation method of the transformer is no-load electric voltage regulation.
▲ Secondary winding: Compression of the transformer body: Coil compression adopts special spring oil cylinder pressure nails, all coils are assembled as a whole and vacuum-dried.
▲ The transformer can be overloaded by 20% for a long time, and has sufficient mechanical strength to ensure that
it can withstand frequent short-circuit impacts.
▲ The transformer is of forced oil circulating water cooling (OFWF) method, adopting a trouble-free forced oil circulating water cooler.
▲ Transformer core materials are made of high-quality products.
▲ Transformer oil adopts 25# oil.
▲ The transformer is equipped with heavy gas, light gas, and pressure releaser protection functions, and the on-load switch is equipped with heavy gas protection functions.
