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.
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 basic raw materials for the production of sponge iron are iron ore, non-coking coal and dolomite. Sizing of the Raw materials also play vital role in sponge iron manufacturing process.
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

What Application of our Sponge Iron ?
Sponge iron filter material (also known as deoxidizer) is made of high quality mineral powder, using the REDOX reaction principle, through out in the form of a filter in addition to the lake to the processed water pipe, boiler circulating water dissolved oxygen corrosion under the dissolved oxygen content can be up to 0.05 mg/L, the deoxidizer has the backwashing frequency is low, high compressive strength, not pulverization, not knot board, specific surface area. The advantages of high activity, the regeneration effect is good.
