Abstract (en)
[origin: EP0212002A2] Roll stand with two work rolls (2, 3), the roll barrels of which have congruent contours with a longitudinal convex curvature and, if required, rest against back-up rolls (6, 7). To produce flat strips, it was known to camber the work rolls (2, 3) in such a way that, after the bending of the rolls under the rolling force, the bending was compensated by the camber and a flat strip was thus produced. It was recognised as a disadvantage that, in practice, the camber chosen was only correct for a particular rolling force and a particular strip width. It is therefore the object of the invention to provide a roll camber with which different strips of different widths can be produced. To achieve the object, it is proposed that the rolls (2, 3) be provided with a camber which varies over their barrel width but is always convex, resulting in a cigar shape of the rolls (2, 3), the largest diameter (D) outside the centre of these rolls but on the other side of the centre (8) of the roll from the respectively opposite work roll (2 or 3). The rolls (2, 3) are adjustable in the axial direction. <IMAGE>
