利用有限元分析软件ANSYS对轧机承载辊缝变形的仿真,分析轧机轧制力、弯辊力及工作辊窜辊对承载辊缝的凸度影响程度,结合现场机架间带钢的浪形,优化二级板形模型设定参数,实现轧机稳定轧制。实践证明,人工修正轧机负荷分配以及CVC轧辊位置,可更好地控制前机架比例凸度,满足后机架间平直度目标的要求,从而提高板凸度的命中率及轧机轧制的稳定性。
The finite element analysis software ANSYS was used to simulate the roll gap deformation of the rolling mill. The influence of the rolling force, bending force and the work roll shifting on the roll crown was analyzed. Combined with the strip shape, Optimize the parameters of the second-level plate model to achieve stable rolling mill. Practice has proved that the manual correction of the mill load distribution and CVC roll position can be better control of the front rack proportional crown to meet the requirements of the straightness between the rear rack to increase the hit rate of the plate crown and mill rolling stability.
