In this paper, with low and medium-TiO₂ content V-Ti-bearing magnetite as the object, its granulation performance, sintering characteristics and the metallurgical properties, phase composition and microstructure of the sinter product were studied. The study results show that, when the basicity decreases from 2.0 to 0.8, the sinter output and quality indexes firstly decrease and then increase. The main mineralogical phases of high basicity sinter are titano-hematite, titano-magnetite, SFCA, perovskite and olivine. The molten composite SFCA is filled in the gap between the Ti-bearing iron ores which connects the iron oxide particles tightly. The reducibility of high basicity sinter is obviously higher than that of the low basicity sinter, but the low temperature reduction disintegration index of high basicity sinter is poor.
