Energy density of electric arc furnace

Producing one ton of steel in an electric arc furnace requires about 400 kWh per short ton (1.44 gigajoules) or about 440 kWh per ton (1.6 GJ); the theoretical minimum energy required to melt one ton of scrap is 300 kWh (1.09 GJ) (melting point 1,520 °C (2,768 °F)). Thus, a 300-ton, 300-MVA EAF woul
