Direct Reduced Iron and its Production Processes IspatGuru

Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using noncoking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.

The largest contributions are from iron ore pelletization, followed by NG supply and coal mining supply chains (for more details, refer to in the Supplementary Material). The coal gasifier and NG reformer DRI processes use iron ore pellets (67% Fe) compared to the rotary kiln process that uses lump ore (% Fe).

Typical ranges of DRI chemistry are 9094% total iron, 8389% metallic iron, % iron oxide, % carbon, % gangue, % phosphorus, and % sulfur. DRI normally has at least 90% of the oxygen removed, with the unreduced oxide present as wustite.

Pathways to decarbonisation episode two: steelmaking technology

In the DRI process, iron ore in the form of lump or pellets is reduced to metallic iron in the solid state unlike in the BF where the material is melted. Today, about 100 Mt of DRI is produced globally each year, with the majority of that using reformed natural gas (essentially splitting natural gas into hydrogen and carbon monoxide) to strip ...

converted into a gas containing hydrogen and carbon monoxide. As the iron ore moves down the furnace through gravity flow, the gas rises through the material column and removes oxygen from the iron carriers. This forms the direct reduced iron (DRI) which is typically composed of 90 to 94% iron. After the DRI exits

Coal based Direct Reduction Rotary Kiln Process IspatGuru

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 carbonaceous material present in the noncoking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).
