摘　　要：针对原料不稳定、高炉喷煤量低、热风炉风温低且不稳定现象,通过加强槽下筛分管理,恢复热风炉助燃空气和煤气的双预热,对炉前输煤管路、喷枪装置进行改造,采用焦丁混装技术等措施,安钢永通2号高炉燃料比由535 kg/t Fe降到了527 kg/t Fe,实现了高炉低成本运行。Based on the unstable raw material, low PCI in BF, low and unstable blast temperature, through the screening strengthening of tank management, hot blast stove combustion supporting air and gas double preheating recovery, the spray gun device and transfer piping transformation before furnace, coke mixed technique, Yongtong No. 2 blast fur- nace fuel ratio was reduced from 535 to 527 kg/t Fe, and realizes the low cost operation of blast furnace.
