Influence of Ordinary Ore Blending Ratio on Texture of Titanium Sinter

The effect of ordinary ore blending ratio on texture of sinter containing titanium was investigated in order to address the problems of low strength and poor low temperature reduction degradation index for sinter in Chengde Iron and Steel Company.The results show increasing percentage of blending ordinary ore leads to reduction in metal phase,and increase in binder phase.Consequently,the content of perovskite reduces and the content of calcium ferrite increases.The texture becomes uniform gradually and turned from granular into melting corrosion structure,the content of skeleton hematite reduce.The drum strength and RDI of resulted sinter are improved.
