    摘要:

    为了降低烧结成本，减少烧结过程能源的消耗，同时提高烧结矿质量，针对某钢铁公司富矿粉烧结进行优化配矿实验研究。选用南非富矿粉、巴西卡粉与南非精矿粉1、2进行了烧结配矿优化研究。结果表明：最优配矿方案为6#，其中巴西卡粉、南非富矿粉、南非精矿粉1配比为15∶70∶15。其利用系数为2.66 t/（m2·h），转鼓指数为63.39%，RI、RDI+3.15分别为70.06%和51.30%，熔滴性能总特性S值为1419 kPa·℃。

    Abstract:

    In order to reduce sintering cost and energy consumption of sintering process, and improve the quality of sinter, we conduct experiments on optimizing the sintering proportion of South African rich ore fines, Brazilian ore fines, South African concentrate ore fines 1 and 2 in a steel company. The results show that the optimal ore matching scheme is No.6. Its proportion of Brazilian ore fines, South African rich ore fines and South African concentrate ore fines 1 is 15:70:15. The utilization coefficient is 2.66 t/(m2·h), tumbler index is 63.39%, RI and RDI+3.15 is 70.06% and 51.30%, respectively, and the value of molten drop performance "S" is 1 419 kPa·℃.
