摘　　要：针对某热连轧生产线无限冷硬工作辊在轧制服役期间辊身剥落及辊颈断裂事故,采用磁粉探伤、金相检测等技术手段进行失效分析,对轧辊制造过程中的质量控制和轧辊使用管理提出改进意见,通过规范操作规程,避免类似事故再次发生。The surface spalling and roll neck breakage of the indefinite chill work rolls that happened during service for a hot strip millhave been analyzed by the means of magnetic particle examination, microstructure examination and other associated techniques to find out the reason why the work rolls failed in operation in order to provide references for the quality control during roll manufacture and the management during roll service. Standardized operation procedures could prevent similar accidents fromtaking place again.

关 键 词：工作辊 探伤 剥落 失效分析
