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 hood, lining, short net , cooling system

exhuast system, de-dusting system, electrode shell, electrode lifting system, loading and unloading 

system, electrode holder,arc burner, hudraulic system, submerged arc furnace transformer and various of 

electrical equipment . 

Product Name :  Submerged arc furnace silicon manganese furnace 

Classification : Self-consuming electric arc furnace 

                         Single-phase arc furnace 

                         Electric arc resistance furnace

Product Description 

Electric arc furnace EAFis 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 3000C , For  smelting metals, EAF is more flexible than 

other steelmaking furnaces. It can effectively remove impurities such as sulfur and phosphorus.
