Abstract (en)

[origin: WO03020452A1] The invention relates to a roll stand for rolling different rolling stock that requires different roll separating forces. The inventive roll stand comprises working rolls, back-up rolls, optionally a roll bending device for the working rolls and optionally a device for adjusting and balancing the back-up rolls, and pairs of adjustment cylinders (3) between the roll stands (1) and the chocks (2). According to the invention, the adjustment cylinders (3) consist of respective telescope cylinders (4), in which a first, concentric cylinder (5) having a large diameter is provided for high roll separating forces and a second, concentric cylinder (15) having a smaller diameter is provided for lower roll separating forces, thereby avoiding high friction losses.
