The influence of the distance from the arc to the walls in the entire range of arc steel-making furnaces with a capacity from 0.5 to 120 tons on the efficiency of arcs and specific power consumption in the furnaces was investigated. In low-tonnage arc steel-making furnaces, the arcs are close to the walls and the efficiency of the arcs is small and amounts to 30-35%, and the specific power consumption for melting is 650 kWh/t. In heavy-duty steel-arc furnaces, the arcs are located far from the walls, the efficiency of the arcs is 46-49% in the absence of a slag layer, and the specific energy consumption for melting is 375-385 kWh/t.
