摘　　要：煤气流的合理分布是提高煤气利用率,维持高炉生产稳定顺行、稳定高炉渣皮、降低燃料消耗的关键所在,而在高炉生产过程中布料矩阵的变化又对煤气流变化起着至关重要的作用。通过调整合理的布料矩阵,改善煤气流的合理分布,首钢长钢9号高炉实现了利用系数为3.5 t/(m^(3)·d),燃料比为500 kg/t铁的生产指标,并向更优异的指标成果迈进。The reasonable distribution of gas flow is the key to improve the utilization rate of gas,maintain the stable and smooth operation of blast furnace production,stabilize blast furnace slag and reduce fuel consumption.In the process of blast furnace production,the change of distribution matrix plays an important role in the change of gas flow.By adjusting the reasonable distribution matrix and improving the reasonable distribution of gas flow,the utilization coefficient of Shougang Changgang No.9 BF is 3.5 t/(m^(3)·d)And the fuel ratio is 500 kg/t iron,and it is striding forward to a more excellent index achievement.
