This paper presents a simple approach for analysing the surface texture transfer in cold rolling of metal strips. The approach made use of the advantages of the slab method and accommodated the surface roughness effect of a rigid work roll. A numerically generated rough surface, whose heights generally follow a Gaussian distribution and distribute transversely, was used in the calculation. The transient distribution of contact stresses and instant texture transfer were then predicted. The interface contact pressure and friction stresses predicted by the established method were verified by the finite element method under the same rolling conditions. It was found that the new approach is efficient and cost-effective. The application of the approach revealed that due to the surface texture of the work roll, the interface stress in the rolling bite can be discontinuous, and that a higher roughness transfer ratio can be expected when reduction ratio increases.
