Abstract

A numerical analysis method for the lubricated skin pass rolling of tin plates with dull work rolls is established considering the surface asperity and elastic deformation of such work rolls. A rolling experiment using dull work rolls of comparable diameter to those used in commercial-scale skin pass rolling mills reveals higher elongation for smaller rolling force and much smaller elongation for larger rolling force compared with elongation behavior in the case of bright work rolls. The results of the numerical analysis exhibit good agreement with the experimental results. The skin pass rolling characteristics with dull work rolls can be explained by the following two factors: (a) localized plastic deformation emanating from the asperity of work rolls and its penetration behavior through the entire thickness of the rolled plate, and (b) geometrically activated friction force due to the asperity of work rolls.
