摘　　要：宝钢3号高炉冷却壁水管过早出现破损,对高炉操作和长寿构成很大威胁.通过分析研究认为:冷却系统设计不合理、冷却强度不够、冷却壁制造工艺存在缺陷、水质控制不好是造成冷却壁水管破损的重要原因.采取安装微型冷却器、人工造壁、炉皮外部打水等应对措施,取得了一定效果.为完全消除冷却壁水管破损的隐患,对S3,S4段冷却壁进行快速整体更换,施工非常顺利.高炉炉况大为改善,在较短的时间内恢复到正常生产水平,从而为炉役后期生产顺行和长寿奠定了基础.The occurrence of early breakage of the water pipe for cooling stave in the No.3 BF threatened seriously the operation of the BF and its service life.It was found that the main causes of the breakage are the unreasonable design of cooling system,low cooling intensity,defective stave and uncontrolled water quality.Several measures were taken to restore the function of stave,such as using miniature cooler,rebuilding the stave and external watering,and good results were thus achieved somewhat.To remove thoroughly the hidden perils of the breakage of water pipe for stave,the cooling staves in the sections S3 and S4 were quickly and successfully replaced integrally,thus improving the furnace conditions greatly.The BF then returned to its normal productivity very soon with a foundation laid down for its future production and prolonged service life.
