How iron is made material manufacture making history Use of Iron Ore Pellets in Blast Furnace Burden

The raw materials used to produce pig iron in a blast furnace are iron ore coke sinter and limestone Iron ores are mainly iron oxides and include magnetite hematite limonite and many other rocks The iron content of these ores ranges from 70 down to 20 or less Coke is a substance made by heating coal until it becomes almost pure carbon Sinter is made of lesser grade finely divided Iron ore pellet can be used as a substitute to sinter and calibrated lump ore in the blast furnace burden due to the following properti Spherical shape and open pores of pellets gives better and uniform permeability resulting in smoother furnace operation
