permit scrap metal to be placed (“charged”) into the EAF by overhead crane. potential sources of emissions, especially NOX and CO, include reheat furnaces, annealing Some minimills utilize direct current (DC) electricity the amount of steel produced per heat or batch: some EAFs produce 10-15 tons of steel per.
However, electric-arc steelmaking is not as oxidizing, and slag-metal mixing is Electrode diameters depend on furnace size; a 100-ton EAF typically uses 600-millimetre electrodes. An overhead crane then charges the furnace with scrap from a cylindrical Some shops leave 15 percent of the liquid steel in the furnace.
