Abstract:
An adjusting arrangement for the roll gap or rolling force in rolling mill stands. The arrangement includes two hydraulic adjusting cylinders which act from both sides on a work roll to be adjusted. The adjusting cylinders each have two or more piston surfaces to which pressure medium can be applied independently of each other, either individually, in any combination, or to all piston surfaces. This makes it possible to adjust the rolling force within the respective rolling force range in such a way that percentage variations of the rolling force are minimized and, consequently, different roughnesses and differences in wall thicknesses can be almost completely eliminated.
