摘　　要：针对高铝烧结矿粉化率高,影响高炉透气性和炉渣性能等特点,通过对烧结矿和钒钛球团矿进行机械强度和冶金性能实验,分析了其与钒钛球团矿搭配的合理性.考察了在其配比不变的条件下,增加钒钛球团矿配比炉料结构的冶金性能及高炉炉渣理论成分含量.当烧结矿比例75%,钒钛球团配入量20%,块矿为5%时,其RI为85.93%,RDI+3.15为71.47%,Ta为1147℃,△Tra为156℃,Td为1349℃,料柱透气性能好,其炉渣TiO2理论含量为8.05%,是相对合理的炉料组成.In allusion to high-alumina sinter with high rate of pulverization and impact on blast furnace permeability and performance of slag,etc.,rationality of sinter with V-Ti pellets was analyzed by experiments of mechanical strength and metallurgical properties of sinters and V-Ti pellets.Then metallurgical properties and theoretical composition of slag of burden structure by increasing V-Ti pellets in the same proportion of sinters studied.When the ratio of sinter was at 75%,V-Ti pellets at 20%,and lump ores at 5%,the burden RI was 85.93%,RDI+3.15 71.47%,Ta 1147℃,Tra 156℃,Td 1349℃,and △Pmax 2223 Pa,it had a good permeability,and the theoretical content of TiO2 in slag was 8.05%.This group was the best burden formed accounting for integrated metallurgical properties.
