“…The results of analytical investigations of arc efficiency were experimentally verified in a 120-t EAF at "Ural Steel" (Open Joint Stock Company) [13]. The experimental melts had included slag foaming by blowing a carbonaceous material through injectors and charging the coke breeze through the roof hole.…”

“…Calculated results of arc efficiency of 120-t EAF depending on slag height are compared with experimental data of energy metering and slag height, obtained on operation 120-t EAFs [13]. Experimental data and measurement results are accordingly as follows: h sl = 356 mm, specific energy consumption q = 203 kWh of liquid steel, η a = 0.67; h sl = 238 mm, q = 260 kWh, η a = 0.52.…”

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.
