Influence of sinter basicity (CaO/SiO2) on low and high ...

Iron ore sinter, constituting a major proportion of blast furnace burden, significantly impacts the blast furnace performance. The chemical composition of iron ore fines, particularly alumina, sinter basicity and sinter MgO together with the thermal conditions that sinter blends are subjected to play an important role in the formation of mineral phases in sinter.

Sinter is better suited to this practice than pellets. Iron Ore Agglomeration Ø Sinter Process The sinter process was introduced around 1910 to treat flue dust extracted from blast furnace exhaust gases. It was quickly adapted to agglomerate fine ore and its use spread rapidly. At the sinter plant, pre-blended fine ore is mixed with:

Iron-ore SInterIng ProceSS oPtImIzatIon
