摘　　要：在轧制力作用下轧机的弹性变形由牌坊弹跳和辊系弹跳相互叠加产生。轧机实际弹跳曲线随轧件宽度变化,受轧制力、轧辊压扁的影响变得更加复杂。介绍了一种通过确定宽度补偿系数K_(B)和轧辊压扁补偿值e,对全辊面零压靠获得的轧机牌坊弹跳曲线进行压扁补偿,获得反映不同宽度规格轧制时轧机实际弹跳方程的方法,并将其简化成C_(0)~C_(7)相关系数表述的轧制模型,明显提高了轧件头部厚度控制的水平。The elastic deformation of the mill under the rolling force is caused by the superposition of the mill housing and the roll stack deformation.The actual spring curve of the mill changes with the width of the rolled piece,and becomes more complicated under the influence of rolling force and roll flattening.A method to obtain the actual spring equation of the mill when rolling with different widths gauges pieces is introuduced by determining the width compensation K_(B) and the roll flattening compensation e,compensating the spring curve of the mill obtained by the full roll surface zeroing.And it is simplified into a rolling model expressed by the C_(0)~C_(7) correlation coefficient,which obviously improves the level of the thickness control of the rolled piece head.
