ABSTRACT:
The rolling mill has two working rolls and at least two supporting rolls. At least both rolls of one roll pair are axially slidable opposing each other and each of the oppositely slidable rolls has a curved contour extending over its entire length which is convex over one longitudinal half segment and concave over the other longitudinal half segment. The contours of both rolls of these roll pairs complement each other continuously in one definite axial position. So that the occurence of increased load points and moreover as a result increased pressure at the contacting positions of the working rolls and the supporting rolls is prevented, the curved contour of the roll body at the free end of the concave longitudinal segment of the roll body extends to the body edges in an at least partially cylindrical longitudinal segment.
