  • Blast Furnace Coke, हार्ड कोक in Middleton Row, Kolkata

    BF Coke fulfills 3 main functions in the blast furnace operation: It acts as a fuel providing heat for all reactions. It acts as a reductant providing Carbon Dioxide gas and carbon for reduction of iron ore, and; It provides the required permeability for movement of gases through the bed of iron ore, coke and limestone inside the blast furnace.Sinter Plant MECON Limited,2016-1-28 · The effect of the self-fluxing sinter is a big asset for BF operations. Basicity (CaO SiO 2) of the sinter should meet the BF demands depending on the sinter ratio in BF. FeO should be 8 10 %.
