摘　　要：对3种不同Al2O3含量的烧结矿进行配加不同用量添加剂的烧结杯实验和冶金性能实验。结果表明:Al2O3质量分数在1.82%～2.2%之间,加入质量分数为0.1%～0.15%的添加剂烧结矿的落下强度、转鼓强度、成品率、低温还原粉化率得到明显改善;此外通过优化配矿,调整Al2O3,SiO2的质量分数比来改善烧结矿的冶金性能具有一定的可行性。Sintering-cup with different amount of additives and metallurgical performance of three different Al2O3 content sinter are experimented.Results show： the down strength,tumbler strength,the rate of finished products and RDI of the sinter with Al2O3 content between 1.8%～2.2%and 0.1%～0.15% additive have distinct improvement;In addition,the method to improve the metallurgical properties of the sinter by optimizing ore,adjusting w（Al2O3）/w（SiO2） has certain feasibility.
