摘要 The theory of metal plastic deformation is an important part of the strip shape control theories. In order to control the shape and gauge accurately during cold thin strip rolling, the mechanism of the metal lateral .ow must be revealed clearly. Therefore, the lateral displacement of thin strip was studied by the grid method. Those grids with a line thickness of 10 lm and clear boundaries were successfully manufactured on the strip surface using lithography. Then, the effects of reduction, front andback tension, and taper angle of the .rst intermediate roll on the metal lateral .ow were studied. The strip shape was calculated with and without considering the lateral displacement; furthermore, the calculations were compared with the measured results. The results show that the calculations with considering the lateral displacement are closer to the measured results. In addition, the comparison of .nite element analysis results with the experimental results indicates that the test method was reliable.
