Modelling of work roll edge contact in thin strip rolling
Work roll contact at the edges forms a new deformation feature in cold strip rolling. In this paper, a modified influence function method is developed to analyse the cold rolling of thin strip when the work roll edges contact. The effect of strip width on specific force such as rolling force, intermediate force and edge contact force, length of edge contact, shape and profile of the thin strip is discussed. The effect of transverse friction variation on the shape and profile of strip is also considered. Results show that the transverse friction has a significant influence on the shape and profile of the thin strip.
