Sponge iron making is a process in which iron ore lumps (typically 5mm18mm size) are tumbled with a 'select' grade of ironcoking coal little dolomite inside 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
Cover Story Indian Sponge Iron Industry SteelworldSponge iron or DRI is obtained from the direct reduction of iron ore. The shape of the ore or agglomerate remains unchanged due to the removal of Oxygen, leaving behind a honey combed microstructure which has suggested the name 'Sponge Iron'. The direct reduction process have some basic advantages which are mentioned below :Direct reduced iron WikipediaChineseDirect reduced iron (DRI), also called sponge iron,[1] is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore Process&ensp·&ensp
Sponge Iron Plant Manufacturers, Suppliers & Exporters Sponge iron is obtained by direct reduction of iron ore. It contains nearly 94% of metallic iron and thus it is vital constituent in steel making process. It is made either by making use of coal or by making iron ore undergo reaction with reducing gases.SPONGE IRON PRODUCTION FROM ORE COAL Abstract: Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal. However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln

Direct Reduced Iron Industrial Efficiency Technology Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BFBOF and ScrapEAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.who make sponge iron from coal and iron ore processHow is steel produced? Quora. Steel is an alloy of iron and carbon. So the primary raw materials we require are iron ore and coal. This iron ore along with metallurgical coke produced from coke oven are fed as raw material into the blast furnace where by reduction process we make pig iron.
Sponge Iron an overview ScienceDirect TopicsN. Selvakumar, in Reference Module in Materials Science and Materials Engineering, 2017 Commercial sponge iron powder production dates back to 1903 with the invention of the Sieurin process in Sweden. Since 1911 the Hoganas Corporation has continuously manufactured sponge iron, although the early use for this product was as a feedstock for steel making.Direct Reduced Iron and its Production Processes Direct Reduced Iron and its Production Processes. Direct reduced iron (DRI) is technically defined as iron ore which has been reduced to metal without melting it. Hot briquetted iron (HBI) is a densified form of DRI to facilitate its handling and transport. History

Processes that produce iron by reduction of iron ore (in solid state) below the meltingSponge Iron Consumption against Metallic Steel Scrap In Grain Size of Sponge Iron: Induction furnaces users always prefer to use fines of sponge iron (Coal Based sponge iron in sizes from 2mm to 5mm) than lumps as fines give better yield and hence less power consumption. So good sponge iron manufactures always try to use iron ore in the size of 5mm to 12 mm, which gives better quality sponge iron.
