板带材轧制开始和结束时刻无张力状态下的轧件跑偏是铝板带热轧生产工艺过程中的重要问题之一。为了减少这两个时间段内轧件的跑偏,利用滑移量与轧件出口速度、滑移量与轧件前后张力之间的定量关系,建立了以前后张力为调节手段的轧件跑偏控制模型。运用大型通用有限元分析软件MSC.Marc进行了仿真计算,验证了该张力纠偏模型的有效性。 One of the most important issues in the hot strip production process of aluminum strip is the rolling off of the strip at the beginning and the end of the strip rolling without tension. In order to reduce the deviation of the rolling stock during the two time periods, the rolling motion with the former tension as the adjusting means was established by using the quantitative relationship between the slip and the exit velocity of the rolling material, the slip amount and the tension before and after the rolling stock Partial control model. The simulation calculation is carried out by using the large-scale common finite element analysis software MSC.Marc, and the validity of the tension correction model is verified.
