Abstract: Vanadium-titanium magnetite is characterized by high content of TiO₂,low content of SiO₂ and the resulting sinter is at low tumbler strength and RDI.In this paper a composite agglomeration process(CAP) was investigated and the resulting sinter performance was compared with conventional sintering process,The research indicated that when raw materials proportioning was kept constant,RDI_+3.15 increased by 5.23%~17.4%,and the tumbler strength index excessed 55% after the implementation of the composite agglomeration process.Compared with conventional sintering,CAP led to the material bed depth increasing from 600 mm to 1 000 mm improvement of vanadium-titanium sinter RDI_+3.15 indicators as well as higher production efficiency.
