Effects of Solid Fuel Types and Ratio on Sintering Process and Metallurgical Property of V-bearing Titaniferous Magnetite Sinter

Based on the material condition of Chenggang sintering state,the effects of solid fuel types and ratio on sintering process and metallurgical property of agglomerate with vanadium were researched.The results show that with the white coal instead of coke powder as solid fuel,the magnetite,silicate and glassiness content in agglomerate decrease,while hematite and calcium ferrite content increase,which make cold mechanical strength and low temperature reduction degradation of agglomerate improve.High solid fuel ratio is not proper for Chenggang sintering.The optimal ratio of coke powder served as the solid fuel is about 5 %;when the white coal serves as solid fuel,the ratio is about 5.5 %～6%.In conclusion,the white coal should be used as solid fuel in Chenggang,while the optimal FeO content of agglomerate with vanadium is about 7%.
