Abstract: The invention relates to a roll stand (1) for rolling a metallic product and having two work rolls supported in the roll stand by respective work roll chocks (2), wherein axial displacement means (3) is provided with which the work rolls can be displaced in direction of their longitudinal axes, wherein at least one work roll locking means (4) is provided with which the work roll chocks (2) can be locked and unlocked in the roll stand (3), wherein rotation prevention means (6) is provided with which the axial displacement means (3) can be prevented from rotation about longitudinal axes of the work roll, and wherein bending means is provided which includes a bending block (5) and with which a bending torque can be applied to the work rolls. In order to achieve a simpler design of the assembly and improved lubrication possibilities for the component to be lubricated, according to the invention, the rotation prevention means (6) and the axial displacement means (3) are fixedly connected with the bending block (5).

Abstract: A roll stand for rolling a metallic product and having two work-rolls supported in the roll stand by respective work-roll chocks. An axial displacement arrangement is provided with which the work-rolls can be displaced in direction of their longitudinal axes, and at least one work-roll locking arrangement is provided with which the work-roll chocks can be locked and unlocked in the roll stand. A rotation prevention arrangement is provided with which the axial displacement arrangement can be prevented from rotation about longitudinal axes of the work-roll. A bending arrangement is provided which includes a bending block and with which a bending torque can be applied to the work-rolls. In order to achieve a simpler design of the assembly and improved lubrication possibilities for the component to be lubricated, the rotation prevention arrangement and the axial displacement arrangement are fixedly connected with the bending block.

Abstract: A roll stand having work rolls mounted therein. The roll stand has at least one upper mounting rail, which is mounted on the drive-side roll stand frame and oriented in a transverse direction to a rolling line running through the roll stand. In order to be able to keep the assembly space in the roll stand over the rolling line free during rolling—except for a roll change—and still change the roll efficiently, the upper mounting rail is configured to be moved into the rolling line and out of the rolling line, starting from the drive-side roll stand frame.
