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. This avoids the step of creating pig iron from iron ore.sp.info Explore furtherFact sheet Energy use in the steel industrywww.worldsteel.orgEnergy Use in Metal Production - Publicationspublications.csiro.auTheoretical Minimum Energies To Produce Steelwww.energy.govsp.info Steel Grating - qunkunmetal.comSteel Grating made by welding with flat steel and cross/round bars with certain distances.
