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 process.

Oct 10, 2019· Sometimes known as directreduced iron, sponge iron is a product that is produced using iron iron ore is often in the form of pellets or lumps, and is subjected to a reduction process that is created by the use of a reducing gas that emits from coal or a natural gas source. This type of iron can be produced in several different types of furnaces, including coke or charcoal ovens, .
Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, 500 TPD) Solid state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI).
Jan 17, 2017· we are trying to take a look at the sponge iron industrie, how we making sponge iron by coal based .if you like please subscribe and comment,please comment your opinion .
The directly reduced iron (DRI) follow different methods of iron making operating below fusion temperature of iron ore to get iron (sponge iron) in solid state using noncoking coal or natural gas as reductant. This ironmaking route has become popular at places who do not have coking coal.
In a direct reduction iron (DRI) process, will 140 ton of iron ore give 140 ton of sponge iron? Assume 14 tonnes of coal, 7 tonnes of lime/chalk and 7 tonnes of bentonite are added to the 140 iron ore mix...

Sometimes known as directreduced iron, sponge iron is a product that is produced using iron ore. The iron ore is often in the form of pellets or lumps, and is subjected to a reduction process ...
outlook of the iron ore mining regions in particular and India in general will become pastoral with such investments. Use of pellets to manufacture sponge iron All most all the coal based sponge iron plants use iron ore lumps. The requirement is generally t/ t of sponge iron. This high requirement is mainly due to the fines generated in

How to use magnetite iron ore to make sponge iron in coal, the idea of the process of how to make sponge iron from iron ore is basically to add coal to remove oxygen from iron by adding non coking coal and to remove sulfur by adding lime stone, the iron ore and coal are crushed in crushers and screened to the recommended sizes (5mm mm ...
Apr 30, 2011· The key difference between sponge iron and pig iron is that we can produce sponge iron by direct reduction of iron ore through reducing agents whereas the production of pig iron is by melting iron ore with charcoal and limestone at very high pressures.. Sponge iron and pig iron are different forms of iron that we can produce from iron ores that occurs naturally under the surface of .
The basic raw materials for the production of sponge iron are iron ore, non coking coal and dolomite. Iron Ore: Iron ore is the source of iron and available in oxide form namely hematite(Fe2O3). As only oxygen can be removed from the iron ore during the process of making sponge iron iron,ores rich in iron content of 65percent and above is ...

Sponge iron is a highly processed form of iron ore which contains metallic iron in the range of 8388% obtained by direct reduction without melting it. Due to high porosity, the resulting iron is called sponge iron. It is used as a raw material for manufacturing steel .
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Sizing of the Raw materials also play vital role in sponge iron manufacturing process. The required size of Iron ore, MPS (Mean particle size), its physical properties like, chemical properties like Fe (T), LOI, gangue content In Sponge Iron Process, two types of coal are being used such as feed coal and injection coal.
Dec 14, 2013· Direct reduced iron (DRI) is also known as sponge iron. It is produced by the reduction of iron ore (in the form of lumps or pellets) by either noncoking coal or a reducing gas produced by reforming of natural gas. The reducing gas can also be produced by the gasification of coal.

INJECTION COAL Coal Crushing Combustion Injection to kiln Coal Injection over a large range of size 020 mm Temperature combustion below 950 C Coal injection system makes use of voal volatiles for reduction, thereby reducing the coal requirement to a minimum Coal ...
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 process is adopted by worldwide conventional sponge iron industries.
out. The role of kiln is to convert the raw material (iron ore, coal and dolomite) into the sponge iron [8]. Detail reaction mechanism of the process is discussed below: There are two reduction reactions. First reaction converts iron ore to iron oxide which further reacts with CO to produce metallic iron (Fe) which is called sponge iron.
