Effect of steel slag ratio on the sintering of vanadium-titanium magnetite ore
To optimize the recycling strategy of steel slag and enhance the economic and social benefits of steel companies,the study first analyzed the content of titanium and phosphorus elements in steel slag and conducted sintering pot tests based on different steel slag ratios.In the vanadium-titanium mag-netite sintering process,with the increase of steel slag ratio,the perovskite phase in sinter increases,and bonding phases transform from SFCA to perovskite phases.This transformation leads to an uneven min-eral phase in sinter and increases its complexity,which has a detrimental effect on the strength of the sintered ore.Additionally,with the increase of steel slag ratio,the phosphorus content in the finished sintered ore also increases.When the steel slag addition amount reaches 5％,the lowest sintering loss rate in the sintering pot test is 15.42％.At a steel slag ratio of 4％,the maximum yield of sintered ore is 86.49％,as the ratio continues to increase,the yield remains relatively stable.
