Abstract：Abstract： In order to investigate the effect of liquid phase generation behavior of sinter blending ore on sinter quality, the basic characteristics of the blended ore at different ratios of ore were analyzed experimentally. The effects of the liquidphase generation behavior of the blending material on phase structure, technical and economic indicators and metallurgical properties of the sinter were investigated by SEMEDS, softeningmelting drop test and other performance measurement tests. The results indicate that the ratio of iron ore has an influence on the liquid phase generation behavior of the blending ore, which in turn affects the sinter quality. The higher the liquid phase fluidity index of the mixture, the easier the sinter is to form a thinwalled structure with large pores, resulting in poor strength. The sinter drum index tends to decrease and then increase with the increase of the assimilation temperature of the blending ore, which is negatively correlated with the liquid phase fluidity index of the blending ore. The liquid phase fluidity index of blending ore increases from 4.67 to 5.53, then sinter drum index decreased from 73.33% to 68.00%. The higher the liquid phase fluidity index of blended ore, the worse the RDI of sinter. In this experiment, when the assimilation temperature of the blending ore is 1296℃ and the liquid phase fluidity index is 4.69, the reducibility of sinter is up to 83.67% and the softening interval of the sinter is the narrowest.
