Investigated the influence of the height of the slag layer in the nomenclature row EAFs, with a capacity from 0.5 to 120 tons, on the efficiency of arcs and specific power consumption in the furnaces. It was found that with an increase in the height of the slag layer, the efficiency of arcs in low-tonnage and heavy-duty furnaces increases and reaches 78…80 % when the arcs are completely immersed in the slag, and the specific power consumption decreases. With an increase in the height of the slag layer and an increase in the efficiency of arcs by 1%, the specific power consumption in the furnaces decreases by 0.75…1.0 %.
