摘要
通过两种单烧性能差的矿粉(毛塔粉和巴西粗粉)组合来代替巴西精粉。混矿原则发挥矿物本身烧结优点,抑制缺点。分析烧结杯各项参数,比较烧结性能,结合矿相分析,得出如下结论:混矿替换巴西精粉后,烧结利用系数和成品率增加,燃耗总体呈降低趋势,转鼓指数并没有降低趋势。矿相分析,除粗粒镶嵌结果有所增加,代替的过程中对矿相影响不大。混矿替代巴西精粉在烧结杯试验过程中可行。
Two kinds of ores （Mauritania ore and Brazilian iron ore）which have poor performance of single firing are used to substitute for Brazilian fine ore.Mixed ore mineral sintering principle gives play to the strong points of min-eral sinter and avoids its shortcomings.Though the analysis of the parameters of sinter pot test and comparison of sintering performance,the conclusions are obtained combining with the mineral phase analysis.When the mixed ore takes the place of Brazil powder,sinter productivity and production yield increase,but the overall fuel consumption shows a trend of decrease and the tumbler index has no trend of decrease.In addition to the increase of some coarse mosaic structure,replacing Brazilian fine ore has little effect on mineral phase on basis of mineralogical analysis.It is feasible for taking the mixed ore instead of Brazilian fine ore in sinter pot test.
