对酒钢7号高炉冷却壁破损后的修复方法进行了探讨。7号高炉开炉两个月后,5段冷却壁冷却水管开始大量破损,冷却壁冷却功能下降,影响了高炉日常安全运行和各项生产指标的进步。通过采取挖补炉壳对冷却壁管根修复,安装微型冷却器和异型冷却器,挖补炉壳安装小块铸铁冷却壁,以及定修造衬等护炉措施,使炉体冷却壁破损趋势得到有效控制,改善了高炉操作条件,为高炉顺行提供了保障。
The repair method of the damaged wall of 7 # blast furnace in Jiuquan Iron and Steel Co. Ltd was discussed. Two months after the opening of No.7 blast furnace, a large number of cooling pipes began to be damaged in Section 5 and the cooling function of cooling stave decreased. All these affected the daily safe operation of blast furnace and the progress of each production index. By taking the remedial measures such as digging the furnace shell to repair the cooling pipe root, installing the micro-cooler and special-shaped cooler, digging the furnace shell to install the small cast iron cooling wall and fixing the lining, etc., the damage tendency of the cooling wall of the furnace body is effectively controlled , Improved blast furnace operating conditions, provided a guarantee for the blast furnace to go forward.
