摘　　要：通过对断裂的股绳机大盘的烘烤处理和技术分析,发现铸造缺陷、运行过程中轮重不等和设计问题是导致大盘产生裂纹和断裂的主要原因。采用二氧化碳气体保护电弧焊替代常规焊条电弧焊技术,并用加固筋板和背板弥补原设计的不足,不仅能保证大盘的修复质量,而且缩短了加工周期,取得显著的效益。By roasting treatment and technical analysis of breakage strander large chuck, the main reasons causing large chuck to produce crack and breakage are as follows ： casting flaw, the weight of wheel not equal while running and designing problems. By using carbon dioxide gas shielded arc welding to substitute conventional welding rod arc welding technology, and using stiffening plate and backing deals to compensate the shortage of original designing, not only the renovating quality is guaranteed, but also the processing time is shortened as well. The economic benefit is obvious.
