对首钢水钢3号高炉(1350m~3)炉缸冷却壁烧坏的处理进行了总结。认为高炉已进入炉龄末期、高炉经过3次停炉和开炉、铁口使用的无水泥炮质量较差是此次高炉炉缸冷却壁烧坏的主要原因。通过采取断开烧坏冷却壁水管、更换冷却壁、对铁口重新进行浇注、炉壳开孔灌浆、加强炉缸部位的检测和监控、强化炉前操作及管理等措施,成功处理了此次冷却壁烧坏事故,确保高炉安全生产,降低了不必要的损失。
The treatment of the storied wall cooling stave of Shougang No. 3 BF (1350m ~ 3) was summarized. That the blast furnace has entered the end of the furnace, the blast furnace after 3 shutdown and open furnace, the use of non-cement gun quality iron mouth is the main reason for the blast furnace hearth cooling wall burnout. By taking measures such as breaking the pipe of the cooling wall, replacing the cooling wall, re-pouring the iron mouth, filling the furnace shell, strengthening the detection and monitoring of the hearth part, and strengthening the operation and management of the furnace, we successfully dealt with this Cooling stave burn accident, to ensure safe production of the blast furnace, reducing unnecessary losses.
