The energy processes in the three main zones of the working space of an electric arc furnace, namely, the zone of charge materials and slag with a low electrical conductivity, the arc discharge zone, and the zone with materials having metallic conduction, are considered. It is shown that the distribution of energy fluxes between these zones in electric ore smelting furnaces and electric arc furnaces determines the efficiency of their dc operation. A general approach to creating high-efficiency melting furnaces is proposed. This approach implies control of the structure of energy fluxes; as a result, energy and raw materials are saved and the ecological characteristics of the processes and the metal quality are improved. © 2014, Pleiades Publishing, Ltd.
