Fatigue failure analysis of Φ380 holding roller

The abrupt fracture of Φ380 holding roller of 1 280 vertical continuous casting machine in TISCO stainless steel plant affected the normal production seriously.The force analysis of the Φ380 holding roller is conducted and the fatigue strength safety factor is calculated in this paper to solve the problem.The static analysis and fatigue analysis for the holding roller are carried out with the software SolidWorks Simulation.The stress cycle before fatigue failure of the Φ380 holding roller was obtained according to the analysis.A specific suggestion on the failure of the holding roller is put forward for further improvement.
