Process Description and flow diagram of Coal

Most of the plants in India use DRI process—a solid state direct reduction process by which iron ore is reduced to sponge without phase change. Raw material mix-iron ore, dolomite and coal are fed to one end of rotary Kiln as well as some fine coal also fed from discharge end and product sponge iron along with char is taken out from the other end.

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) to 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 point of iron. Reduced iron derives its name from these processes, one example bein

WELSPUN STEEL LIMITED

The process of sponge iron making aims to remove the oxygen from iron ore. The quality of sponge iron is primarily ascertained by the percentage of metallization (removal of oxygen), which is the ratio of metallic iron to the total iron present in the product. Sponge iron manufacture is highly sensitive to raw material characteristics.

Energy survey of the coal based sponge iron

01-09-2015  In the sponge iron process concentrated and finely divided iron ore is reduced in solid phase into sponge iron at high temperatures in rotary kiln. The process is very energy demanding. In order to identify the largest losses and to find ways to increase the efficiency, an energy survey of the sponge iron plant was carried out for a number of different production rates.

Direct reduced iron process - tec-science

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Direct reduced iron process - tec-science

Sponge iron is a highly ferrous ore from the direct reduced iron process! In order to prevent excessive re-oxidation of the sponge iron in the ambient air, it must be cooled down in the lower region of the shaft furnace. Carburisation as in the blast furnace process does not occur in the DRI-process, as coke is not used as a reducing agent. Thus the carbon content of the sponge iron remains relatively low at

Direct Reduced Iron and its Production Processes

DRI has a porous structure. This is because DRI is produced by removing O2 from iron ore. It is also known as sponge iron since its structure is just like sponge with a network of connecting pores. These pores results in a large internal surface area which is around 10,000 times greater than the internal surface area of solid iron.
