Direct reduced iron
Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 °C (1,470 to 2,190 °F) in the presence of the reducing gas syngas , a mixture ,...
