摘　　要：由于对小于10 mm的小粒级烧结矿含量指标的要求越来越严格,因此,分析在烧结以及供料过程中破坏烧结矿粒级组成的原因,并提出具有针对性的改善措施。实施改善措施后,生产的烧结矿<10 mm粒级含量(质量分数)指标得到了明显的改善,由41.02%降到了38.85%,高炉炉料的透气性得到了明显的改善。Because the index requirements of sinter of small fraction content less than 10 mm become more and more strict, this paper analyzes reason of sinter grade destruction in the process of sintering and feeding, and puts forward the corresponding improvement measures. After the implementation of improvement measures, the fraction content（mass fraction）index of produced sinter 10 mm obviously improves, from 41.02% to 38.85%, and the permeability of blast furnace burden is obviously improved.
