Patent ID: 8881569

Claim:
A rolling mill stand for the production of rolled strip or sheet metal, comprising working rolls having a barrel contour described by a non-linear function, extending in a common length direction, and together defining roll nip, and a respective supporting roll outward of the nip at each working roll and supporting the working roll, at least one of the supporting rolls having marginal regions of a longitudinal extent thereof, and the at least one of the supporting rolls having a barrel contour which runs over an entire effective barrel length of the at least one of the supporting rolls and is described by a non-linear function, and the barrel contour of the at least one of the supporting rolls having a chamfer in at least one marginal region of its longitudinal extent each chamfer forming a corrected barrel contour in the at least one marginal region, the corrected barrel contour being described by a non-linear function, a first pitch of the barrel contour and a second pitch of the corrected barrel contour being identical at the transition point from the barrel contour to the corrected barrel contour, the corrected barrel contour being obtained by subtracting a non-linear mathematical chamfer function from the barrel contour described by the non-linear function, the load distribution between the at least one of the supporting rolls and the working roll contacting the at least one of the supporting rolls being equalized over the barrel contour of the at least one of the supporting rolls in comparison to the load distribution between a supporting roll with a cylindrical barrel contour and a working roll with a barrel contour described by a concave-convex function over the barrel contour of the supporting roll outside of the marginal regions of the supporting roll.
