An additional benefit of DRI steelmaking is that the main reaction runs at a lower temperature and therefore requires less energy. The reduction of iron ore takes place in a shaft furnace at a relatively low temperature of about 1,000°C. The reduced iron is then further processed into liquid hot metal in an electric furnace.Web
