In allusion to the existing material conditions of blast furnace in Shuicheng I﹠S Corporation, rationality of sinter with VTi pellets is studied through metallurgical performance tests of single ore. Regularity for change of reducibility, reduction degradation index, melting and dropping index changes of burden structure are researched, at increased VTi pellets in the same proportion of sinters and different proportion of imported lump ores. The results show that sinter RI reaches 90.68%, integrated charge RDI and soft melting index are improved by adding vanadiumtitanium pellets. The charge structure is the best when VTi pellets ratio at 20%, which softening starting temperature is 1 147 ℃, softening range is 156℃, dripping temperature at is 1 349 ℃, maximum pressure is 2 223 Pa and has a good permeability.
