摘　　要：研究了烧结配矿中钒钛磁铁矿用量对烧结利用系数、燃耗和低温还原粉化率的影响,结果表明,烧结矿中Ti O2含量增加1个百分点,烧结产量下降11.1%,固体燃耗增加3.99%,RDI+3.15 mm降低3.96个百分点;根据烧结低温还原粉化率与高炉产量和燃料比的影响关系,将使得高炉铁水产量降低3.04%,焦比增加11.01 kg/t HM。通过本分析,可定量地评估钒钛磁铁矿对烧结、高炉炼铁的影响。Effect of vanadium titanium magnetite on sintering productivity,fuel rate and low-temperature reduction degradation index(R D I)was studied.Results indicated that when Ti〇2 content in sinter was increased by 1 percentage point,the sintering output was decreased by 1 1.1%,the solid fuel consumption rose by 3.99%and RD/+315 nini fell by 3.96 percentage points.According to the correlation between RDI and fuel rate,the hot metal production from blast furnace w ill be reduced by 3.04%and coke rate w ill be increased by 11.01 kg/tHM.Based on such analysis,the effect of vanadium titanium magnetite on sintering and blast furnace iron-making can be quantitatively evaluated.
