摘要针对六辊UCM可逆冷轧机的断面形状控制问题，首先通过模拟计算揭示冷轧带钢的变形机理，分析中间辊窜辊、工作辊弯辊、中间辊弯辊3种调控手段对带钢断面形状与平直度的控制效果，指出3种调控手段的局限性；然后分析了工作辊辊型对带钢断面形状与平直度的控制效果，得到辊型设计的基本原则；进而提出一套适用于UCM可逆冷轧机的“辊型精细优化＋目标平直度调整”的断面形状控制技术方案，最终提高了冷轧边缘降控制效果。将上述技术方案应用于3套1 420 mm UCM可逆冷轧机，硅钢横向同板差显著减小，为同类轧机断面形状控制提供了有益参考。

Abstract：Aiming at the profile control of the cold rolled strip in the 6-high reversible universal crown mill （UCM），the deformation mechanism of cold rolled strip was revealed by simulation calculation. The control effects of the intermediate roll shifting and bending and the work roll bending on the profile and the flatness were analyzed，and limitations of these control methods were noted. Then，the control effects of the work roll contour on the profile and the flatness were analyzed，and the design principles of work roll contours were obtained. On the basis of this，a technical scheme named "fine optimization of roll contours＋ adjustment of flatness target " was proposed for the reversible UCM，which finally improved the control effect for the strip edge drop. The technical scheme was applied to three sets of 1 420 mm reversible cold rolling UCM，and the transverse thickness difference of the silicon steel was significantly reduced，which provided a useful reference for profile control methods of similar rolling mills.
