Coal / Coke IPM Commodities

With its strong base in South Africa, IPMC is a reliable source for South African non-coking coal with moderate GCV, typically for sponge iron application. IPMC has also been sourcing sized coal from South Africa which is considered to be an ideal and more economical partial replacement of nut coke used by the ferroalloy smelters. Other than this, it also has established contacts to source non-conventional semi-anthracite thermal coal from other parts of the African

Sponge Iron an overview ScienceDirect Topics

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO

Direct Reduced Iron Industrial Efficiency Technology

Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF 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.

The coal use in advanced plants is between 1.05 1.2 t-coal/t-DRI, which equals 20 25 GJ/t-DRI. This is significantly larger than the 15 19 GJ/t-DRI value obtained by using coal with 16% non-combustable fraction in South Africa. The counter-current rotary kilns used for DRI production in India only allow about 60% of the heat to be used for reduction, revalorization of the remaining 40% that is discharged

Sponge Iron Manufacturer India

Sponge Iron also called Direct reduced iron (DRI), 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 processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron
