Sponge iron is a metallic product produced through direct reduction of iron ore in the solid state. It is a substitute for scrap and is mainly used in making steel through the secondary route. The process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product.
Properties of Sponge Iron
• High iron content and high degree of metallization
• Uniform and consistent quality
• Lower sulphur and phosphorus content
• Negligible tramp element
• Minimum dust generation during material handling
• Good flow ability in bins, pipes and conveyors for continuous and trouble free charging
• Superior technical support to induction furnace operators
