Roll line

Device for rolling of rolling stock, the device comprising:

• at least one pair of rolls;
• a linear drive comprising at least one of a downstream linear drive which is arranged downstream of the at least one pair of rolls in a rolling direction and an upstream linear drive which is arranged upstream of the at least one pair of rolls in a rolling direction, wherein the linear drive is configured to apply tensile stress in the rolling direction to the rolling stock through the at least one pair of rolls;
• a tensile stress detector;
• and
• a controller configured to receive a detected tensile stress in the rolling direction 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 in the rolling direction detected by the tensile stress detector, and wherein the controller is configured to either (1) vary the magnitude of the tensile stress in the rolling direction applied to the rolling stock and/or (2) to keep the magnitude of the tensile stress constant behind a roll gap.
