对鞍钢常用4种铁精矿的烧结基础特性进行了试验研究,在此基础上,采用最优试验设计方法,建立了烧结合理配矿的统计模型,给出了烧结获得最佳和最差烧结指标值时的各种矿的定量搭配关系,提出了鞍钢烧结合理配矿方案。优化配矿工业试验结果表明:烧结技术经济指标有不同程度改善,尤其是烧结矿的粒度组成改善、固体燃耗降低;提出并确定了球团配加铁精矿A的优越性,配加铁精矿A后,皂土配比降低8.69%,转鼓强度提高035个百分点。
The basic sintering characteristics of 4 kinds of iron ore concentrate used at AISC were investigated. On the basis of the results, the statistic model of proportioning ore for sinter was established by optimal design of experiment. Using this model, the proportion of each kind of ore was obtained for obtaining optimum and worst sintering indexes. The optimum proportioning ore was proposed. The industrial trial results of optimum ore proportioning show that sinter techeconomic indexes, especially including sinter ore size distribution and solid fuel consumption are improved. It was found that adding iron ore concentrate A for pelletizing has superiority, the bentonite proportion is reduced by 8.69% and drum strength is increased by 0.35%.
