Synopsis Three-dimensional analysis for strip rolling, in which elastic deformation of rolls and plastic deformation of a strip are treated as one system, is expanded to calculate the nonsymmetric deformation of both rolls and strip and applied to evaluate the off centering or cambering of a strip and the fundamental characteristics of snaking of a strip. The phenomena of nonsymmetric rolling and off-centering or cambering of a strip can be predicted accurately by the present analysis.
