Steelmaking arc furnace inputselectric energy into furnace by graphite electrode. Electric arcproducing between electrode tips and furnace burden is used as heatsource to smelt steel. The heat source of electric arc furnace iselectric energy. Atmosphere inside the furnace can be adjusted,which is helpful to melt steels containing easier oxidation ofelements. SH series three-phase steelmaking arc furnace is used tosmelt high-quality carbon steel and all kinds of ferro-alloy steel.The designed volume is from 0.5-150t. And the rate power oftransformer can reach

120MVA.
