摘　　要：对莱钢3 200 m^3高炉低燃料比冶炼实践进行了总结。通过优化操作,细化高炉管理,采取提高煤气利用率的措施,推进低硅冶炼,高炉实现了长期稳定顺行。在年平均矿比1.713 t/t的原燃料条件下,平均燃料比降至513 kg/t。This paper reviews the low fuel ratio smelting practice of Laiwu Steel＇ s 3 200 m^3 BF. By optimizing the operation, refining the blast furnace management, taking measures to improve the gas utilization and promoting low silicon smelting, the BF has realized long-term stability anterograde. Under the raw materials and fuel condition with the annual average ore ratio 1.713 t/t, the average fuel ratio was reduced to 513 kg/t.
