高炉冷却壁破损直接影响高炉正常生产和威胁炉体寿命。而关键部位的冷却壁破损后一般较难处理。包钢1号高炉于1991年8月因炉体破损严重进行中修,投产后不到两个月,发现风口带第四段12号冷却壁破损,该冷却壁面积2.67m~2,其右下方为北渣口。破损后表现为11,12,13号风口与二套、二套与大套之间向外渗水,北渣口不能放渣。以往用常规方法处理效果都不理想。于是我们采用了一种名为“太空胶”的产品对破损冷却壁进行补漏。具体方法如下:安装水槽(0.6m~3)、水泵(型号IS50-32-125,扬程20m)和管道,形成闭路循环供送系统,单独给破损的12号冷却壁供水。同时,采用如下辅助措施:增加蛇形冷却水管冷却这一部分循环水;调节控制冷却水的pH值等于7,以防管道结垢;测量计算冷却壁
Blast furnace stave damage directly affects the normal production of the blast furnace and threatens the life of the furnace. The cooling of the key parts of the damaged wall is generally more difficult to deal with. Blast furnace No. 1 in Baotou in August 1991 due to severe damage to the furnace repair, put into operation less than two months and found that the fourth paragraph of the tuyere with No. 12 stave damage, the cooling wall area of 2.67m ~ 2, the right Below the North slag mouth. Damaged after the performance of No. 11, No. 12, No. 13 and two sets of tuyeres, two sets and large sets of water seepage between the North slag mouth can not put slag. In the past using conventional methods to deal with the effect is not ideal. So we used a product called “space glue” to trap damaged staves. The specific method is as follows: Install a water tank (0.6m ~ 3), water pump (Model IS50-32-125, head 20m) and pipe to form a closed-circuit circulation feeding system, and separately supply the damaged No.12 stave. At the same time, the following assistive measures are adopted: adding a serpentine cooling water pipe to cool this part of the circulating water; adjusting the pH of the control cooling water to be equal to 7 to prevent pipeline fouling; measuring and calculating the cooling wall
