ABSTRACT:
A rolling mill, especially a hot flat-rolling mill, comprises a pair of working rolls which are supported either directly or via intermediate rolls on a pair of supporting rolls, the pair of working rolls being mutually axially displaceable. To permit far-reaching influencing and compensation of the bending of the rolls which occurs due to thermal cambering and under load, and of the roll gap changes which are produced thereby, and thus to achieve optimum profile control and flatness control of this rolling mill, each of the mutually axially displaceable working rolls comprises a hollow roll with a cavity designed to be rotationally symmetrical in relation to a longitudinal axis of the roll and asymmetrical in relation to an imaginary transverse plane inter-secting the longitudinal axis at a center of the roll crown. The first and second working rolls include identically designed cavities turned through 180.degree. with respect to each other.
