Sponge ironmaking is aprocessin whichiron ore lumps(typically 5mm-18mm size) are tumbled with a ‘select’ grade ofiron-coking coal little dolomiteinside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished product bunkers prior to dispatch.

Theprocessofsponge ironmaking aims to remove the oxygen fromiron ore. The quality ofsponge ironis primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio ofmetallic ironto the totalironpresent in the product.Sponge iron manufactureis highly sensitive to raw material characteristics.

Mar 15, 2004·Sponge iron processfor manned space exploration. TheSponge Iron Process(SIR) is a well-known technology for the production and purification of hydrogen. It consists of a cyclicprocessin which a feed gas, rich in carbon monoxide and hydrogen (e.g. syngas), is passed on anironoxide (magnetite Fe3O4) at high temperature.

Theprocessofsponge ironmanufacturing involves removal of oxygen fromironore. When that happens, the departing oxygen causes micro pores in the ore body, turning it porous. When the eventual product is observed under a microscope, it resembles a honeycomb structure, which looks spongy in texture. Hence the namesponge iron.

DRI, also known assponge iron, is the product of reducingironoxide in the form ofironore and steel plant wastes into metalliciron, below the melting point ofironand typically in the range of 800–1200 °C.Ironoxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet,ironore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

Direct reducediron(DRI)process. In addition to theprocessroute via the blast furnaceprocess, there is another option for extracting crude steel fromironores using the so-called direct reducediron(DRI)process(secondary route).The starting point for the efforts to find an alternative to the blast furnaceprocesswas the relatively highprocessexpenditure.

Sponge ironis produced by roasting pyrite and reducing theironoxide calcine at temperatures in excess of 1500°F. with coal in a Bruckner revolving furnace followed by cooling to 150°F. in an enclosed Baker cooler. The resultingspongeproduct is ground to —35 mesh for use in the precipitation circuit of the L-P-Fprocess.

Sometimes known as direct-reducediron,sponge ironis a product that is produced usingironore.Theironore is often in the form of pellets or lumps, and is subjected to a reductionprocessthat is created by the use of a reducing gas that emits from coal or a natural gas source. This type ofironcan be produced in several different types of furnaces, including coke or charcoal ovens, blast ...

Ironore and non-coking coal are the prime raw materials for the production ofsponge iron. These are charged into a rotary kiln in requisite proportion along with some dolomite. Coal plays a dual role in theprocessby acting as a reductant as well as a fuel for providing heat to maintain the requisite temperature inside the kiln at 950-1050 o C.
