ABSTRACT:
A rolling mill frame for the rolling of different rolled stock which requires different rolling forces and which has working rolls, back-up rolls, optionally a roll being device for the working rolls and optionally a device for adjusting and balancing the back-up rolls. The mill has pairs of adjusting cylinders between the roll stand and the chocks of the rolls which avoid large friction losses. The adjusting cylinders are each comprised of a telescoping cylinder in which a first cylinder with a large diameter for high rolling forces and a concentric cylinder with smaller diameter for smaller rolling forces are provided.
