中文摘要：

针对富矿粉烧结工艺的改善,通过系统的烧结试验对烧结工艺参数中的燃料比、烧结负压和烧结料层厚度进行了研究。结果表明,随着燃料比的增加,烧结利用系数先升高后下降,转鼓指数持续升高;随着烧结负压的升高,烧结利用系数先升高后降低,转鼓指数持续降低;随着料层厚度的增加,烧结利用系数先下降后升高,转鼓指数持续升高。根据灰色加权关联度选出最优工艺参数为燃料比为5.0%、烧结负压为12 000 Pa、料层厚度为600 mm。

英文摘要：

Fuel ratio, sintering suction and sinter thickness were studied through systematic experiments to improve the sintering process of rich ore fines. The results showed that with the increase of fuel ratio, sintering utilization factor first increased and then decreased, and drum index increased. With the increase of sintering section pressure, sintering utilization factor first increased and then decreased, and drum index decreased. With the material thickness increasing, sintering utilization factor first decreased and then increased, and drum index increased. According to the grey weighted related degree, the best technological parameters were chosen as follows： the fuel ratio is 5.0% ,the sintering section pressure is 12 000 Pa, and the material thickness is 600 mm.
