摘要
针对内蒙古大唐国际托克托发电有限责任公司循环水泵轴开裂,经化学成分、金相组织、机械性能等分析,找出了轴开裂的原因是热处理不良导致轴本身的力学性能不合格而发生了开裂。
Cracking was found in pump spindle of water circulating pump at Inner Mongolia Datang International Tuoketuo Power Generation Co.Ltd.Analysis was performed on the cracking zone by chemical compositions analysis,metallographic examination and mechanical properties testing to find the cracking reason.The results show that the unqualified mechanical properties resulted from unsuitable heat treatment process induced the cracking.
