Abstract
The production of carbon steel by the continuous addition of prereduced iron ore to molten auto scrap in an electric furnace appears to have certain operational advantages over conventional cold-melt, batch-charging techniques. Among these are: (1) Lower tramp metal content in the ingot, (2) shorter heat times and lower electrical energy consumption, (3) improved energy input rate during the continuous addition, and (4) flexibility of charge composition by varying ratios of scrap to prereduced iron.
