[0002] Sponge iron (DRI), also known as direct reduced iron, is mainly used to replace scrap steel in electric arc furnace steelmaking. In recent years, due to the shortage of scrap steel, the production of sponge iron has received increasing attention. Its output has gradually increased from 800,000 tons in 1970 to 33.3 million tons in 1996. There are more than 40 sponge iron production processes in the world, and 20 of them are in industrial application.
