摘　　要：针对酒钢4#高炉炉役后期风口频繁破损的原因进行分析,结合高炉炉役后期炉体破损状况,通过采取提高入炉品位控制、优化焦炭配置、降低碱负荷、降低煤比、强化炉况管理工作等措施治理风口破损,确保了炉役后期高炉安全运行。Based on the analysis of the causes of frequent breakage of tuyere in the late service of the 4#blast furnace in Jiusteel,the safety operation of the blast furnace in the late service is ensured by improving the control of the inlet grade,optimizing the distribution of coke,reducing the alkali load,reducing the coal ratio and strengthening the management of the furnace condition.
