iron pellet reduction in sponge iron kilns

Direct reduced iron WikipediaWELSPUN STEEL LIMITED

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 reductionSponge iron is a metallic product produced through direct reduction of iron ore in the solid state It is a substitute for scrap and is mainly used in making steel through the secondary route The process of sponge iron making aims to remove the oxygen from iron ore

A study on the accretion formation in DRI kilns and OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION

Abstract Direct reduction of iron ore with aid of either carbon or natural gas under controlled temperatures and pressures within a rotary kiln generates sponge iron as a product However rotary kiln performance is adversely affected by the ring formation known as accretion These accumulated sintered solid particles which1 Krupp Sponge Iron Process The Krupp Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets Fig 1 The feed is introduced together with reducing and de sulphurizing agents lime stone or raw dolomite into an inclined rotary kiln heated counter current to the flow of hot gas and reduced to form sponge
