Abstract (en)
In order to minimise the dog-bone and fish-tail deformations of a slab (1) during width rolling, the rolling surfaces (3) of the rolling elements (8) have a radius of curvature of at least 0.6 m. The radius may be e.g. 5 m. To avoid the technical and economic drawbacks of cylindrical rolls of this radius, the rolling elements (8) have a curved surface (3) in the zone of rolling contact extending for an angular length of less than 180 DEG , preferably less than 90 DEG . Preferably the rolling elements (8) are less thick, in the direction transverse to the rolling direction, than the radius of curvature of the curved surfaces (3). They may be arcuate segments running on guide rollers (14). The segments may be flexible, the radius of curvature being determined by the positions of the guide rollers (14). The curved surface may be provided by an endless conveyor (15) running on guide rollers.
