对凌钢1080m~3高炉炉壳开裂的处理实践进行了总结。通过分析炉皮开裂的原因,采取“定尺切挖、整体更换、高压灌浆”的有效措施,解决了炉缸炉壳大面积开裂、严重漏煤气的问题。
The paper summarizes the cracking practice of blast furnace shell in 1080m ~ 3 blast furnace. By analyzing the reason of furnace cracking and adopting the effective measures of “cutting by length, overall replacement and high-pressure grouting”, the problem of large-scale cracking of furnace shell and serious gas leakage has been solved.
