Abstract:
A roll stand with multiple rolls for rolling strip-shaped rolling stock, the roll stand comprising:a roll frame;an upper working roll and a lower working roll mounted on the roll frame in a common vertical roll axis plane, wherein the strip-shaped rolling stock is guided between the upper and lower working rolls forming a roll set;upper support roll insert parts and lower support roll insert parts mounted on the roll frame;two upper support rolls mounted in the upper support roll insert parts and configured to support the upper working roll, and two lower support rolls mounted in the lower support roll insert parts and configured to support the lower working roll;the two upper support rolls and the two lower support rolls arranged symmetrically to the vertical roll axis plane, respectively;working roll bending devices mounted on the roll frame and configured to act on the upper and lower working rolls;balancing devices mounted on the roll frame and configured to advance and balance the upper and lower support rolls;the two upper and two lower support rolls configured to be axially moveable independently from one another in a common direction or in opposite directions relative to a vertical center plane of the roll frame, extending perpendicularly to the vertical roll axis plane, by a same or a different axial displacement length in order to compensate roll set bending of the roll set of the working rolls and to provide adjustment to a width of the roll stock for the purpose of flexible rolling via the working rolls.
