Energy Use in US Steel Manufacturing

Electric Arc Furnace. In an electric arc furnace (see Fig. 2), scrap steel and solid pig iron is melted using an electric arc. The electric current passes through the steel, heating it a high degree. Since electricity is used to heat the metal, new steel can be created entirely from scrap steel.

Steel manufacture

Modern electric arc furnaces can make up to 150 tonnes of steel in a single melt. The electric arc furnace consists of a circular bath with a movable roof, through which three graphite electrodes can be raised or lowered. At the start of the process, the electrodes are withdrawn and the roof swung clear.
