Abstract
Results of analytically studied effect of electromagnetic blowing and the slag height on the arc efficiency are stated. An arc is blown from under an electrode toward the furnace walls under an electromagnetic force, arc radiation on the wall and roof increase and effective output, absorbed by the metal decreases. EAF (electric arc steel melting furnace) with independently powered arcs, eliminating its electromagnetic blowing is proposed. When arcs are powered independently, its efficiency increases significantly, and specific energy consumption decreases.
