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

Factors affecting Coke rate in a Blast Furnace IspatGuru

Jun 29, 2014· The first one is iron bearing materials which are sinter, pellets and calibrated iron ore (CLO). Higher iron (Fe) content in these materials means lower gangue material is going inside the furnace which needs to be fluxed for slag formation. Hence higher Fe content helps in the reduction of slag volume and coke rate.
