  • Sintering Process Equipment Used in Iron and Steel

    Sinter is the primary feed material for making iron in a blast furnace Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous beltfed furnace Sinter feed composition control is important because the various sinter feed materials are not perfectly characterized and theirof sinter which do affect the blast furnace performance This has got significance in view of the fact that while most of the burden materials are the product of nature with inherent variability in physical and chemical properties, sinter is produced in the plant whose quality can be regulated through control of sintering condition and requisite chemistry of sinter Simultaneously, aCHAPTER11 FUNDAMENTALS OF IRON ORE SINTERINGSecondly, why sinter is used in blast furnace?

  • Blast furnace Wikipedia

    A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper Blast refers to the combustion air being "forced" or supplied above atmospheric pressure In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with· A blast furnace (BF) is the most common process for hot metal production in the world The BF is charged with metallurgical coke and ironbearing materials separately, which leads to a layered structure The ironbearing materials consist of iron ore pellets, lump ore, and sinter When the charge material descends, it is reduced by CO and H 2 In the ideal situation, ironbearing materialsReduction of Iron Ore Pellets, Sinter, and Lump Ore underIn the present work, blast furnace sludge and its flue dust are used as substitutes of primary raw materials in the form of pellets in sintering Processing waste fines and utilized these fines in sinter helps to eliminate raw material flux and improves furnace productivity This recycling method provides the optimum sized of the sinter, greater than 10mmEffect of Sintering Performance of the Utilization of

  • The choice of pellets in a mixed blast furnace burden and

    When used in mixed (sinterpelletlump ore) burdens this has not always been regarded as an advantage, as it is the properties of the mix that needs to be optimised, rather than that of an individual component Therefore, the first objective, when the LKAB Experimental Blast Furnace was ready for operation in 1998, was to develop and test a pellet specially designed to give good blast furnace
