中板轧机主传动万向接轴辊端接头断裂事故分析

Faults Analysis on Joint Break of Universal Coupling for Medium Plate Mill

采用机械测试、三维有限单元、金相组织分析等现代综合分析技术 ,对中板轧机主传动万向接轴辊端接头断裂事故进行分析。

Nanlyzed the reason that caused the joint break of universal coupling on medium plate mill is described,using modern synthetic analysis methods that are check mechanical parameters,3D finite element and metallographic examination. The main reason of the accident is non-correct thermal treament method.
