One of the most important applications of sponge iron is in induction furnaces and raw iron and steel production. It can be said that the use of sponge iron in induction furnaces can replace nearly 50% of scrap. But its application in induction furnace requires technical knowledge and experience. Also, the use of sponge iron is a big change in the continuous casting of the steel industry. It can be used in almost all steel production methods. Many small and large steel production units in the country use these methods. Sponge iron is a good substitute for iron waste, therefore, a high percentage of raw materials to meet the melting requirements of steelmaking units can be supplied through sponge iron instead of using waste.
