摘要
大环件轧机的芯轴连续发生断裂。采用断口检测、金相检验、电镜能谱和力学性能测定的方法对芯轴断裂的原因进行了分析。结果表明,所用材料的显微组织缺陷和耐热性能差是导致芯轴发生早期断裂的主要原因。
Core axes of roll mill had been ruptured continuely.It was investigated by means of fracture analysis and microstructure examination,SEM energy spectrum analysis and mechanical properties testing.The result showed that defects of microstructure in the core axes and poor heatproof of the material were the main reasons for earlier rupture of the core axes.
