Analysis of the Influence of Blaine Numbers and Firing

Aug 18, 2020 The Blaine fineness of the available iron ore decides various factors such as heat consumption, strength of the pellet’s structure, and porosity of the structure. The pellet’s strength at higher temperature gives burden stability. The pellet’s porosity decides the reduction rate of iron oxides inside the blast furnace.

Reducibility of iron ore pellets and effect of additions

Dec 01, 1973 AbstractThe effect of lime and silica addition on the reducibility, of sintered iron ore and synthetic hematite pellets was investigated. The addition of lime and/or silica (up to about 10% total) to sintered synthetic hematite pellets has little effect on the reducibility at 900°C. Lime additions (with or without silica) lower the reducibility of sintered hematite and magnetite ore pellets.
