距离尾棍最近的一根下托辊是热处理网带炉传动装置的重要零件,它的突然断裂将影响网带等部件的使用寿命,严重的甚至将影响正常生产。通过对下托辊材料质量和断裂口进行金相组织分析、硬度梯度的检测,以及托辊结构强度简析,并利用Pro-E软件进一步进行有限元疲劳分析来验证,总结出下托辊断裂的原因,从而提出针对性的改进建议,有效防止下托辊的断裂,保证生产的连续进行,降低成本。
The next roller from the tail stick is an important part of the heat treatment furnace belt drive. Its sudden rupture will affect the service life of the mesh belt and other components, even seriously affecting the normal production. Based on the analysis of the microstructure, the hardness gradient and the structural strength of the idler roller under the condition of the material quality and the fracture opening, Pro-E software was used to carry out further finite element analysis to verify the failure of the lower roller Of the reasons, so as to put forward suggestions for improvement, effectively prevent the breakage of the next roller, to ensure the continuous production, reduce costs.
