Sponge iron
Direct-reduced iron (DRI), also called sponge iron, is produced from direct of (in the form of lumps, pellets or fines) by a reducing gas produced from or coal. The reducing gas is a mixture majority of (H2) and (CO) which acts as reducing agent. This process
of directly reducing the in solid form by reducing gases is called direct reduction.
The conventional route for making consists of or plants, , , and . Such plants require high and raw materials of stringent specifications. is needed to make a strong enough to support the burden in the blast furnace. Integrated steel plants of less than one million
tons annual capacity are generally not economically viable. The coke ovens and sintering plants in an integrated steel plant are polluting and expensive units.
Specification
Sponge Iron is mainly used as a raw material for speciality steel as well as substitute for scrap. Made from iron ore, sponge iron in itself is not used. It is further processed to make wrought iron. The rise in price of scrap and other factors have led to the increase
in the use of sponge iron for making high quality steel.
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. Sponge iron manufacture is highly sensitive to raw material characteristics.
Therefore, it is essential to examine the chemical and physical characteristics of raw materials, both individually and in combination.
The sponge iron is a key raw material for the manufacture of steel. The appropriate percentage of metallization (removal of oxygen) ensures the high quality of the sponge iron. The percentage of metallization is the ratio of metallic iron to the total iron present in
the product.
