四辊轧机花键轴早期失效分析

The Earlier Period Failure Analysis of Spline Shaft for a 4-Roll Rolling Mill

四辊轧机的花键轴服役四个月便发生了早期失效。经扫描电镜断口分析确认 ,是腐蚀疲劳所致。

The earlier period failure of the spline shaft for a 4-roll rolling mill occurred after an operating period of 4 months.This is confirmed by SEM that it is caused by corrosion fatigue.
