    in the steel industry The blast furnace is therefore expected to retain its dominant position in the production chain from iron ore to crude steel The reduction of iron ore and the carburization of reduced iron at high temperatures are the two key processes in blast furnace ironmaking that consume the highest amounts of energy [7]For this reason, pellets are preferred over fine powder as blast furnace feed The preparation of iron ore pellets begins with the crushing and grinding of iron ore into a fine powder, and adding reducing additive coke (C) and binding agents and mixing The mixture is added to a pelletizing machine or ball mill along with a pre determined amount of moisture to form green pellets These green pellets are air dried and subsequently oven dried to harden the pellets Green pellets(PDF) Sample Proposal for an Iron Ore Pelletizing PlantA blast furnace is the dominant process for making iron in the world Iron ore pellets are commonly used as iron burden materials in a blast furnace, in which iron oxides are reduced to metallic molten iron While descending, the charge faces various stresses, which affect the gas flows in the shaft and the energy efficiency of the processC 617 ACTA Oulu

  • Ironmaking 101 – From Ore to Iron with Blast Furnaces

    10102017· Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities The iron ore is dressed or crushed into 051 in chunks, which increases surfaceThese pellets are spherical in shape and are of 1 to 2 cm in diameter These pellets are porous and allow for a better air flow and heat distribution through the pellet, resulting in a better reduction into iron in the blast furnace For this reason, pellets are preferred over fine powder as blast furnace feed The preparation of iron ore(PDF) Sample Proposal for an Iron Ore Pelletizing Plant30012020· Reduction of Iron Ore Pellets, Sinter, and Lump Ore under Simulated Blast Furnace Conditions Anne Heikkilä,* Mikko Iljana, Hauke Bartusch, and Timo Fabritius 1 Introduction A blast furnace (BF) is the most common process for hot metal production inReduction of Iron Ore Pellets, Sinter, and Lump Ore under
