In order to achieve the goal of resource utilization of High-Ti vanadium titanomagnetite (High-Ti VTM), the high-temperature sintering characteristics of High-Ti VTM were investigated by micro-sintering experiments, while the effects of different ordinary iron ore dosage and basicity on the sintering process parameters and sinter quality were investigated by sintering pot experiments. The results showed that the TiO2 and SiO2 contents increased gradually with increasing dosage of High-Ti VTM, and the liquid phase fluidity index and binder phase strength increased gradually, while the assimilation temperature and intergranular consolidation strength showed a decreasing trend. With the increase of the dosage of ordinary iron ore, the vertical sintering speed was reduced, while the sinter yield and tumble index gradually increased. As the basicity of the sinter gradually increased, the sintering time and the pulverization degree of the sinter gradually increased and the sinter yield gradually decreased, while the vertical sintering speed and the tumble index both showed a trend of first increasing and then decreasing. The results of the study provide data to support the preparation of sinter with High-Ti VTM.
