Electric arc furnace requirements for electrical energy are increasing more rapidly than generation and distribution capacity. Electric arc furnace technology is reviewed with respect to energy requirements. Although the use of water-cooled panels, increased power levels and higher oxygen inputs, for example, all increase the rate of energy loss, they do not necessarily result in an increase in energy losses per ton. The increase in loss rate (energy/hour) may be more than offset by a decrease in cycle time. This article attempts to summarize the impact of various process variable discussed in a recent report on electric arc furnace efficiency issued by the Electric Power Research Institute's (EPRI) Center for Materials Production (CMP). These include meltshop logistics, operating practices, energy input, scrap preheating and pollution control.
