| 摘 要： | 针对目前广泛使用的CVC和HC两种主要轧机机型,利用大型有限元软件ANSYS 9.0建立了三维辊系有限元模型,分析了不同机型的四辊和六辊轧机在不同窜辊、弯辊工况下的轧制力纵向刚度和弯辊力纵向刚度的变化情况.在相同工况下的四辊轧机的轧制力纵向刚度要大于六辊轧机.中间辊窜辊或工作辊窜辊对HC轧机的轧制力纵向刚度和弯辊力纵向刚度的影响要大于CVC轧机.

| Abstract: | Aimed at CVC and HC mill types which are widely used, finite element models of 4-high and 6-high mills were established through ANSYS9.0 software. The vertical rigidities of rolling force and bending force were analyzed under different working conditions of roll shifting and bending force by the model. It is revealed that the vertical rigidity of rolling force of the 4-high mill is larger than that of the 6-high in the same working condition. The axial shifting of the intermediate roll or work roll has a greater effect on the vertical rigidities of rolling force and bending force of the HC mill than the CVC mill. |
