建立了UCMW冷连轧机辊系与轧件一体化仿真模型．由工作辊弯辊、中间辊弯辊、工作辊轴向移位、中间辊轴向移位确定不同仿真工况，分析了各调控手段对带钢中心凸度和边缘降的调控能力．详细研究了带钢厚度、张力、压下率、变形抗力等对边缘降的影响．结果表明，工作辊弯辊对带钢中心凸度的控制能力最强，工作辊轴向移位对带钢边缘降的控制能力最强，各影响因素对边缘降的影响程度都大于对中心板凸度的影响．说明带钢边部对轧制因素的变化更敏感．

英文摘要：

A special integral simulation model for lastic deformation of rolls and the three-dimensional a UCMW cold roiling mill was introduced based on the eplastic deformation of strips. The strip center crown and edge drop control performance of work roll bending, intermediate roll bending, work roll shifting and intermediate roll shifting were compared and analyzed through the simulation model. The influences of strip thickness, forward and backward tension, reduction ratio and resistance to deformation on the edge drop were investigated in detail. The results indicate that the strip center crown control ability of work roll bending and the edge drop control ability of work roll shifting are the strongest. The effects of all the factors on the edge drop are more than those on the center crown. It is shown that the edge of a strip is more sensitive to rolling conditions.
