为探讨济钢目前烧结原料结构条件下固体燃料粒度对烧结矿产质量的影响,通过改变固体燃料粒度中<1 mm的比例进行烧结杯试验。结果表明,随着固体燃料粒度中<1 mm比例的降低,垂直烧结速度加快,烧结矿成品率、利用系数、转鼓强度、平均粒径等指标明显改善,对降低固体燃料、烧结内返粉和高炉槽下返粉将起到重要作用。生产中应稳定四辊操作,适当放宽输出粒度范围,杜绝固体燃料的过粉碎现象。

A study is carried out on the influence of solid fuel particle size in sintering on sinter yield and quality by changing the proportion of<1 mm particle size solid fuel in sinter pot test. The results showed that when the<1 mm particle reduced, the vertical sintering rate increased, indexes such as sinter yield, utilization factor, tumbler strength and average particle size are remarkably improved, therefore greatly reducing solid fuel cost, return fines in sintering and under bin of BF. It also points out that the four roller operation should run smoothly, particle range should be properly widened and over powder phenomenon of solid fuel particle should be avoided.
