Sponge Iron - Direct Reduced Iron Bloom With Up To 3% Slag | Energy-efficient Feedstock For Specialty Steel 제조업체

We are the largest manufacturer exporter and supplier of low price Sponge Iron in Kolkata West Bengal India. Sponge iron also called direct reduced iron is the product created when iron ore is reduced to metallic iron usually with some kind of carbon (charcoal etc) at temperatures below the melting point of iron. This results in a spongy mass sometimes called a bloom consisting of a mix of incandescent wrought iron and slag. Sponge iron is not useful in itself but can be processed to create wrought iron. The sponge is removed from the furnace called a bloomery and repeatedly beaten with heavy hammers and folded over to remove the slag oxidise any carbon or carbide and weld the iron together. This treatment usually creates wrought iron with about three percent slag and a fraction of a percent of other impurities. Further treatment may add controlled amounts of carbon allowing various kinds of heat treatment (e.g. "steeling"). Today sponge iron is created by reducing iron ore without melting it. This makes for an energy-efficient feedstock for specialty steel manufacturers which used to rely upon scrap metal.
