Melting electric arc furnace

Equipment overview

The steelmaking electric arc furnace uses an electric arc as a heat source.and uses scrap steel(iron) as a raw material to smeltspecial steelmaking equipment such as carbon steel, high-quality carbon steel alloy structural steel tool steel, stainless steeland the like.

The electric arc furnace generally uses a furnace cover to unscrew the upper feed, and the EBT eccentric bottom tapping opera-tion mode. The electrical part of the main component mainly includes high and low voltage system,transformer, reactor and PLCcontrol system.The mechanical part mainly includes furnace cover,furnace body,tlting mechanism, rotating mechanism, liftingmechanism, electrode lifting mechanism, high current circuit and cooling system. , hydraulic system, etc.

The electric arc furnace can be produced continuously or intermittently, with strong adaptability, and can be matched with thecontinuous development of perfect refining and continuous casting and rolling technology. Electric arc furnace is an importantsteelmaking equipment that plays an important role in steel production.
