摘　　要：酒钢4#高炉中修开炉运行仅1 a后出现炉腹、炉腰、炉身下部冷却壁大量破损,已影响到高炉的操作及生产稳定。结合4#高炉中修后的生产实际状况,并与3#高炉对比,分析冷却壁破损的原因,并提出相应对策,为缓解炉身冷却壁损坏改善高炉运行提供依据。After only one year of operation,a large number of damage occurred in the furnace belly,waist and lower cooling wall of 4#blast furnace in Jiusteel,which has affected the operation and production stability of the blast furnace.Based on the actual production condition of 4#blast furnace after repair,and compared with 3#blast furnace,the causes of cooling wall damage are analyzed,and corresponding countermeasures are put forward,aiming at providing basis for alleviating the damage of cooling wall of furnace body and improving the operation of blast furnace.
