摘　　要： 采用修正的影响函数法建立了UCM轧机辊系弹性变形的计算模型,分析了带钢宽度、轧辊直径以及弯辊力大小等因素对轧机处于无穷大横向刚度时中间辊横移位置δm的影响规律,结果表明δm值随带钢宽度和弯辊力的增大而增大,随工作辊直径的增大而减小。通过工业实验验证了在实际生产中可以通过设定中间辊横移位置尽量接近δm以获得高的横刚度,从而提高轧机板形控制的稳定性,改善带材的板形质量。 A modified influence function method was used to analyze the roll elastic deformation of UCM mill. The effects of strip width, roll diameter and roll bending force on the special intermediate roll position δm where infinite lateral rigidity can be obtained were discussed. Results show that δm increases with the increase of strip width and roll bending force, but decreases with the increase of work roll diameter. During rolling process, high lateral rigidity can he obtained by setting intermediate roll position near to δm. By doing this, the stability of shape control will be enhanced and the strip shape will be improved, which was proved by industrial experiment.
