马钢10号高炉挂管冷却喷涂造衬实践

Practice of welding water-cooled pipe and gunning of Maanshan Steel's No. 10 BF

马钢10号高炉炉腹、炉腰处炉壳变形严重,冷却壁损坏率达100％。利用中修机会,成功地采用了挂管冷却加喷涂造衬方式对炉腹、炉腰部位进行了整体更换,取得了较好的效果。

Shell deformation of bosh and bosh parallel of Maanshan Steel's No. 10 BF was serious,and damaged rate of cooling stave reached 100%, so welding water-cooled pipe on shell and guning were adopted with success during intermediate repair,and there is a good effect.
