Abstract

Heat transfer and arc efficiency of the electric arc furnaces (EAF) of Consteel (DSP-120co) and conventional (DSP-120ob) designs, equipped with the modern melting process intensification means, have been analyzed. For comparison purposes, EAFs of similar capacity and performance were used. As a result of analysis, it was found that the average arc efficiency of the Consteel DSP-120co furnace is 8 to 9% lower than that of the DSP-120ob furnace. The analysis of the EAF arc efficiency made it possible to explain the higher specific energy consumption by the DSP-120co compared to that of the DSP-120ob furnace.
