Abstract (en)
[origin: WO2014174099A1] The invention relates to a method and a rolling stand (100) for cold rolling rolled stock. The rolling stand (100) comprises at least one upper and one lower backup roll (110-1, 110-2) and also an upper and a lower work roll (120-1, 120-2), which define a roll gap (128). Optionally, a lower and an upper intermediate roll (130-1, 130-2) may also be provided between the work rolls and the backup rolls. In order to ensure an absolutely equal circumferential speed of the upper and lower work rolls when cold rolling in skin-pass mode, it is proposed according to the invention to decouple the upper or lower work roll from its associated drive device.
