Abstract: 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.
Abstract translation: 本发明涉及一种用于冷轧轧制坯料的方法和轧机机架(100)。 轧制机架(100)包括至少一个上部和一个下部支承辊(110-1,110-2)以及上部和下部工作辊(120-1,120-2),它们限定了一个辊间隙 128)。 可选地,也可以在工作辊和支承辊之间设置下中间辊(130-1,130-2)。 为了确保在皮肤通过模式下进行冷轧时,上下工作辊的圆周速度绝对相等,根据本发明,提出了将上下工作辊与其相关联的驱动装置分离。
