Sintering Pot Test on Improving TiO₂-Containing Ore’s Allocated Proportion

Abstract:

The effects of different TiO2-containing ore’s allocated proportion on quality, mineral structure and sintering process of Xuan steel sinter were studied in this paper. The results showed that the increasing of the TiO2-containing ore’s allocated proportion was disadvantageous to the sinter sample’s anti-compressive strength, and the yield and tumbler strength of sinter were decreased although the velocity of sintering was improved. The tumbler strength decreased from 68.67% to 63.33%, and the main reason is that the content of perovskite increases and the content of calcium ferrite decreases with the increasing of TiO2-content in the sinter. The TiO2-content in the sinter should be controlled less than 1.3% considering effect of TiO2-content on sintering process, burdening and iron making of blast furnace in all.
