Sintering pot test on improving TiO_2-containing ore's allocated proportion

摘要

The effects of different TiO_2-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 TiO_2-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 TiO_2-content in the sinter. The TiO_2-content in the sinter should be controlled less than 1.3% considering effect of TiO_2-content on sintering process, burdening and iron making of blast furnace in all.
