PELLET and noncoking coal are the prime raw materials for the production of sponge iron through. The process of sponge iron making aims to remove oxygen from PELLET. When that occurs, the departing oxygen causes micro pores in the ore body making it porous.

SEML was one of the first companies to install a sponge iron plant in the Siltara, Raipur area. Sponge Iron or Direct Reduced Iron is produced by reducing Iron Ore (in the form of lumps/pellets) using noncoking coal in a rotary kiln. The coal acts as the fuel as well as a reducing agent Oxygen is removed from the Ore to produce Sponge Iron.
The MIDREX® Shaft Furnace can use natural gas or a syngas from coal or coke oven gas as its reductant. MIDREX® Plants commonly operate in excess of 8000 hrs per year. In addition, the MIDREX® Shaft Furnace has been proven in using the widest variety of oxide pellets or lump ores to produce CDRI, HDRI and/or HBI.
Sponge Iron Directreduced 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.
Direct Reduced Iron. 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.
Mathematical modelling of the sponge iron reactor (SIR) Introduction to the sponge iron reactionThe sponge iron reaction is utilised as core hydrogen production mechanism of the RESC by reducing and subsequently reoxidising iron pellets (the socalled contact .
DRI – DIRect ReDuceD IRon. Normally in the form of sponge pellets or lumps varying between 6 and 25mm nominal diameter, but often 8 to 12mm diameter. The IMO BC Code classes this product as "a material that is hazardous only when in bulk" (MHB). It can be found under the BC Code as BC015.
The low grade iron ore deposit of PurBanera Belt of Rajasthan has remained unexploited even though it was explored by Geological Survey of India, way back in the year 196970. Af

Iron Ore / Pellets, furnaces and sponge iron, having inadequate captive source of iron ore Assmang Iron Ore from South Africa is exported through . Sponge Iron Suppliers, Manufacturers .
Sponge iron manufacture is highly sensitive to raw material characteristics. Therefore, it is essential to examine the chemical and physical characteristics of raw materials, both individually and in combination. The basic raw materials for the production of sponge iron are iron ore, noncoking coal and dolomite.

We operate two "Ore to metal" integrated steel manufacturing plants, one in Sambalpur, Odisha and one in Jamuria, West Bengal which comprise of captive railway sidings, captive power plants, iron pellet, sponge iron, billet, TMT, wire rod, structural mills and ferro alloy plants.
Direct Reduced Iron (DRI) is created by heating iron ore in a steel shaft with natural gas, below the melting point. The resulting iron pellets can be used as a replacement or
Iron ore pellets with a nominal 64 67% Fe, uniform porosity and better size help in faster reduction and higher metallization rates than the conventional iron ore lumps. The inherent higher mechanical strength and abrasion resistance of pellets enhance the production rate of sponge iron by approx. 20% under identical operating conditions.
Sponge iron reaction Wikipedia. The sponge iron reaction (SIR) is a chemical process based on redox cycling of an ironbased contact mass, the first cycle is a conversion step between iron metal (Fe) and wuestite (FeO), the second cycle is a conversion step between wuestite (FeO) and magnetite (Fe 3 O 4).
The sponge iron produced contains 8090% metallic iron dep ending on the type of materials charged as mentioned in Table3. . The source of sulphur in composite reduced pellet is internal coal. The sulphur content in the composite reduced pellets containing 6% internal anthracite coal is .
Sponge Iron. Sponge Iron is the metallic product formed by the reduction (removal of oxygen) of iron ore at temperature below the fusion point of iron while it is still in .
Directreduced 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 (H2) and carbon monoxide (CO) which acts as reducing agent.
