SPONGE IRON – Lloyd’s Metals

Sponge iron making is a process in which iron ore lumps (typically 5mm-18mm size) are tumbled with a ‘select’ grade of iron-coking 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 finished product bunkers prior to dispatch.Direct reduced iron - Wikipedia,Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting,Sponge Iron - an overview | ScienceDirect Topics,Charging of coal and iron ore is performed through a lock hopper system. The reducing gas contains 65–70% CO,, which produces “ sponge iron.” In this process, the oxygen is removed without melting the ore. Iron oxide ores extracted from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction reaction, as the iron ore is heated with carbon, it results,sponge iron process,29.07.2010· In general sized iron ore of 5-18mm is used in the process of manufacture of sponge iron on all types of rotary kiln with +16mm not exceeding 15-20%.The mean particle size of iron ore shall be restricted to 11mm in order to achieve uniform Fe metallic of all grain size fraction of the product. The mean particle size ratio of iron ore to feed coal shall be in the range of 1.2 to 1.5 depending,who make sponge iron from coal and iron ore process,Direct reduced iron - Wikipedia, the free encyclopedia . Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal.The reducing gas is a mixture majority of hydrogen (H 2) and carbon monoxide (CO) which acts as reducing agent. .

The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron. Depending on its content of volatile matter, the coal is part-ly blown into the,The Application and Benefits of Sponge Iron - PK Steel,21.01.2019· Sponge iron is a metallic product produced through the direct reduction of iron ore in the strong state. It is a substitute for scrap and therefore is mostly applicable in making steel through the secondary route. The procedure of sponge iron making aims to expel the oxygen from iron ore. The level of metallization (expulsion of oxygen) shows the quality of sponge iron. It is the proportion of,Energy survey of the coal based sponge iron industry,,01.09.2015· The actual process of the coal based sponge iron production is based on SL/RN process (jointly developed by the Steel Company of Canada, Lurgi Chemie, Republic Steel Company and National Lead Corporation in 1964), which works on direct reduction of ore.This process is adopted by worldwide conventional sponge iron industries.Coal based Direct Reduction Rotary Kiln Process –,14.02.2017· The coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the melting of the materials. The process has the advantage of low capital expenditure and no requirement of coking coal. The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing,

Steelmaking - Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.How is Iron Refined from Ore? (with pictures),To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to. Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.,,,,
