Selecting corresponding rolling force model, the paper make an experiment and studies on cold rolled paper-thin strip processing characteristics of sixteen-roll rolling machine based on cold-rolled theory aand forms corresponding rolling model, tension model and moment calculation model .And comes to a conclusion that distortion force and press utmost have a large effect on rolling force and paper-thin strip shape, primarily presenting paper-thin strip rolling subarea theory that rolling force decreases corresponding to the thick decrease of strip but increases rapidly when to a certain thick.

结合带钢冷轧基本理论，选用适当的轧制压力模型，针对十六辊轧机轧制极薄带钢时的工艺特点进行了实验和分析，建立了相应的张力模型及辊系传动力矩模型；并得出变形抗力及压靠对轧制极薄带钢时的轧制力和板形有很大的影响，初步提出了当带厚较大时，为保持板形良好，随着轧件厚度的减少，轧制压力相应降低，当轧制到一定厚度时，轧制压力随着带厚的减少急剧增加的极薄带轧制分区理论。
