Abstract

Rolling stand for producing rolled strip, which includes work rolls, which are supported on backup rolls or intermediate rolls and backup rolls. The work rolls and/or the backup rolls and/or the intermediate rolls can be axially shifted relative to one another. The barrel length (L) of each intermediate roll in a six-high rolling stand or of each work roll in a four-high rolling stand has a cylindrical roll barrel section (Z) and a convexly curved roll barrel section (R(x)), such that the transition point from the cylindrical to the curved roll barrel section, calculated from the cylindrical end of the roll barrel, is in the range of L/2≦x<L. The curved contour, which extends towards opposite ends of the two rolls over a portion of the barrel, is described by a polynomial R(x)=ao+ . . . anxn, where n≧5.
