Mill stand

A mill stand having a device for stabilizing the working rollers and back-up rollers of the mill stand while a rolling stock is being rolled to form a strip, the mill stand comprising:

• an upper and a lower working roller for rolling the rolling stock to form the strip,
• an upper and a lower back-up roller for supporting the working rollers in the mill stand,
• an operator-side and a drive-side mill stand housing,
• an operator-side and a drive-side working roller chock, the working rollers being rotatably mounted in the working roller chocks,
• operator-side and drive-side bending blocks for deflecting the working rollers,
• an operator-side and a drive-side back-up roller chock, the back-up rollers being rotatably mounted in the back-up roller chocks,
• wherein,
• for each bending block, there are at least two first hydraulic pressing units for stabilizing the working rollers in the mill stand housing, the first hydraulic pressing units being arranged upstream of the working roller in the transport direction of the rolling stock (TR), each first hydraulic pressing unit comprising a piston with a piston rod and a pressure plate, the piston and the piston rod being integrated in the bending block and the pressure plate being able to be pressed hydraulically against a working roller chock;
• for each mill stand housing, there is at least one second hydraulic pressing unit for stabilizing the back-up rollers in the mill stand housing, the second hydraulic pressing unit being arranged downstream of the back-up roller in the transport direction of the rolling stock (TR), the second hydraulic pressing unit comprising a piston with a piston rod and a pressure plate, the piston and the piston rod being integrated in the mill stand housing and the pressure plate being able to be pressed hydraulically against the back-up roller chock, at least one of the first hydraulic pressing units contains a first oscillation absorber, which reduces pressure oscillations that occur in a pressure chamber of the at least one first hydraulic pressing unit.
