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.

Hydrogenbased direct reduced iron, or H 2DRI, gives challenges to steel producers. When conventional electric arc furnace (EAF) is used to melt H 2DRI, gangue content of iron ore needs to be low, otherwise the slag generation and iron losses will increase drastically in the EAF processes. Only less than 3% of world iron ores fulfill ...

Direct Reduced Iron Direct reduced iron is produced by the reduction of iron ore by carbon monoxide and hydrogen, as illustrated in simplified form in the equations below: Fe 2O 3 + 3CO → 2Fe + 3CO 2. Fe 2O 3 + 3H 2 → 2Fe + 3H 2O . There are several processes for direct reduction of iron ore, principally gasbased shaft furnaces

Pathways to decarbonisation episode two: steelmaking technology

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 away the oxygen from the iron ore. DRI, or its compacted form hot briquetted iron (HBI), is a versatile feedstock that can be utilised in the BF or BOF to ...
