The effect of arc length on heat exchange and specific power consumption in electric arc steel-making furnaces was studied. A modern electric arc steel-making furnace (EAF) with a capacity of 100-tons of metal, EAF-100, was used as the study model. With an increase in the arc length from 300 to 425 mm, that is, by 1.42 times and with a constant height of the slag layer, the thermal radiation fluxes of arcs on the walls increased by 1.3-1.6 times whereas the arc efficiency decreased by 30% and the specific power consumption increased by 25-30%.
