The invention relates to a device for rolling, in particular for stepped rolling, of rolling stock with at least one pair of rolls and at least one linear drive arranged downstream of the pair of rolls in the rolling direction, which together with the pair of rolls can apply tensile stress to the rolling stock, and with means for detecting the tensile stress. In order to enable an improved method of flexibly rolling stock, the rolling device is characterized by means for detecting the tensile stress and by a control device for controlling the drive power of the linear drive as a function of the tensile stress detected, in order optionally to vary the tensile stress applied to the stock or to keep the tensile stress constant as the drive speeds behind the roll gap change. The invention also relates to a method of rolling the rolling stock using such a device.
Device for rolling of rolling stock with at least one pair of rolls and at least one linear drive which is arranged downstream of the at least one pair of rolls in a rolling direction and which, together with the at least one pair of rolls, can apply tensile stress to the rolling stock, the device comprising a tensile stress detector and a controller configured to receive a detected tensile stress from the tensile stress detector, wherein the controller is configured to control the drive power of the linear drive at least in part as a function of the tensile stress detected, in order optionally to vary the tensile stress applied to the rolling stock or to keep the tensile stress constant behind a roll gap.
