摘　　要：针对水钢现有原料条件,通过对单一矿石冶金性能的测试,研究了水钢烧结矿搭配钒钛球团矿的合理性;在烧结矿配比不变的条件下,用进口块矿对钒钛球团矿配比的加入进行调节,研究了炉料结构的还原性,低温还原粉化性和荷重软化及高温熔滴性能的变化规律。试验结果表明,水钢烧结矿还原度(RI)达到了90.68%,钒钛球团矿的加入有利于综合炉料低温还原粉化性能RDI和软熔性能的改善,其中当钒钛球团配入量为20%时,炉料结构软化开始温度为1147℃,软化区间156℃,滴落温度1349℃,最大压差2223Pa,透气性良好,为最佳炉料组成。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.
