Abstract：The inactivation and scaling of backup rolls in 3500 mm plate mill at Shougang Group are caused by nonuniform contact pressure distribution as well as stress concentration at the edges of rolls. An analytic model of roll elasticity deformation based on the influence function method was developed to simulate the rolling process. The effects of rolling parameters such as plate width, roll contours, chamfer and straight chamfer parameters on the contact pressure distribution were studied. The results show, that for wide plate and roll with concave contour, the contact pressure distribution tends to be uniform, the stress concentration at the edges of rolls is influenced by chamfer parameters. This analysis can be used as the basis for optimizing design of the roll contour, and enhancing the roll service life.
