摘要
通过对铁路车辆车轴典型冷切断裂事故的分析及原因的查找,指出在冶金企业内部开展超声波探伤的重要性和必要性。同时,依靠马钢探伤技术的优势和便利,通过在马钢适时开展重点车辆车轴的普查机会,根据马钢的生产与检修的特点,建立起适合目前马钢车辆检修状况的超声波探伤检修机制与工作模式。
The importance and necessity of carrying out ultra-sonic test（UT） in metallurgical enterprises were pointed out through analyzing cold fracture accidents of axles of railway cars and probing the causes of the fractures.At the same time,UT inspection mechanism and operation mode suitable to the maintenance conditions of Masteel＇s railway cars were established based on the advantages and convenience of Masteel＇s defect inspection technology and the characteristics of production and maintenance of the company.
