摘　　要：为了得到适合永昌钢铁1 350m3高炉的最佳煤比,对该高炉的过程参数进行了分析,研究了高炉喷煤量与风温、富氧、焦比、燃料比、煤气利用率的关系,并分析了不同煤比下的综合效益指数,结果表明:在目前的原料条件和生产条件下,适合永昌钢铁1 350m3高炉的最佳煤比为150kg/t左右。In order to get the optimal pulverized coal rate of 1 350 m^3 blast furnace in Yongchang Iron and Steel Co. , Ltd. , operating parameters of the blast furnace were analyzed. The relationship between pulverized coal injection rate and blast temperature, oxygen enrichment, coke rate, fuel rate, gas utilization efficiency was studied. The integrative benefit index under different coal rate was also analyzed. The results showed that the optimal coal rate of 1 350 m^3 blast furnace in Yongchang Iron and Steel Co. , Ltd. was 150 kg/t under present conditions of raw materials and operations.
