摘　　要：为降低高炉渣中w（Al2O3），采用烧结杯试验进行了配加低Al2O3精矿的烧结试验。结果表明：随着2种低w（Al2O3）精矿配比的增加，烧结矿的w（TFe）逐渐升高，烧结矿的w（Al2O3）逐渐降低；随着低铝精A配比从5%依次增加到10%、15%，烧结矿的w（TFe）从56.59%依次升高到56.65%、56.77%，w（Al2O3）从2.04%依次降低到1.87%、1.81%；随着低铝精B配比从5%依次增加到10%、15%，烧结矿的w（TFe）从56.40%依次升高到56.53%、56.62%，w（Al2O3）从2.04%依次降低到1.92%、1.83%。结合烧结矿的产量、质量指标分析得出，最佳配矿方案是低Al2O3精矿A的适宜配比范围为5%～10%，而低铝精B的适宜配比范围为10%～15%。In order to reduce w（Al2O3） of blast furnace slag, sintering experiments adding low w（Al2O3） concentrate were carried out using sintering pot test. The results showed as follows： with increase of the two low w（Al2O3） concentrate ratio, w（TFe） of sinter risen and w（Al2O3） of sinter reduced gradually. When the ratio of low w（Al2O3） concentrate A increased from 5% to 10%, 15% w（TFe） of sinter risen from 56.59% to 56.65%, 56.77% and w（Al2O3） reduced from 2.04% to 1.87%, 1.81% respectively. When the ratio of low w（Al2O3） concentrate B increased from 5% to 10%, 15%, w（TFe） of sinter risen from 56.40% to 56.53%, 56.62% and w（Al2O3） reduced from 2.04% to 1.92%, 1.83% . According to yield and quality index of sinter, the best scheme of ore matching for sintering was that the suitable matching range of low w（Al2O3） concentrate A was 5%～10%, and the suitable matching range of low w（Al2O3） concentrate B was 10%～15%.
