Optimal Sintering Conditions for Blast Furnace Ironmaking

The sintering process is utilised to convert weakly-bonded iron ore granules into a partially fused porous sinter cake using coke breeze as fuel, and then into final product iron ore sinter with specific properties. In a typical sinter strand, air is drawn down and a flame front is allowed to propagate at 1200~1400℃ through the granule bed.

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

Abstract. 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.
