摘　　要：根据国丰钢铁公司的原料和操作条件,分别研究了高炉炉渣中不同含量的未燃煤粉对高炉终渣流动性能、熔化性温度和熔化温度的影响.结合炉渣矿相分析得出,在现有操作条件下,国丰炉渣中未燃煤粉的比例不宜超过9%,煤比应控制在150kg/t左右.为国丰钢铁公司进一步开展富氧大喷煤、降低综合燃料比提供了理论依据.Under the conditions of raw materials and operation of Guofeng Iron and Steel Group Co.,Ltd.,the influences of unburned pulverized coal in blast furnace slag on the properties of fluidity,melting properties and melting temperature were investigated,and the mineral analysis was also done.In the conditions of present raw materials and operation,the unburned pulverized coal content should be controlled under 9%,at the same time the best pulverized coal injection rate should be limited at 150 kg/t or so.So thes...
