摘　　要：介绍了首钢原料条件下配加扬地粉对烧结生产影响的实验室研究。随着扬地粉配入量的增加，烧结矿转鼓强度、成品率改善，燃耗有少量上升，利用系数增加，低温还原粉化指数变差。研究结果表明：在首钢目前条件下，配入10％～20％的扬地粉是可行的。二烧车间进行了扬地粉工业试验，其最高配比达到30％，工业试验时烧结各项指标变化与实验室试验结果基本一致。Influence of Yangdi iron fine ore addition on sintering was studied. The laboratory results show that the drum strength of sinters is improved, the fuel rate and productivity are increased, and RDI is decreased with the increase of Yangdi fine ore content. It is feasible to add that 10%-20% Yangdi Fine ore. The industrial trial was done in the second sinter plant, the maximum ratio of Yangdi fine ore was 30%. The results were similar to the laboratory ones.
