Brief introduction of submerged arc furnace
Submerged arc furnace is a kind of industrial furnace which consumes much power. Full set
equipment mainly consist of furnace shell, fume hoods, lining, short net. cooling system, exhaust system,
de -dusting system, electrode shell, electrode lifting system. loading and unloading system.
Product Description
Electric arc furnace is an electric furnace for smelting ores and metals at high temperature produced by
electrode arc. When gas discharge forms arc, the energy is very concentrated , and the temperature of arc
region is above 3000 C. For smelting metals, EAF is more flexible than other steelmaking furnace. It can
effectively remove impurities such as sulfur and phosporus.
