A rolling device has an upper and a lower work roll and at least one upper and one lower backup roll. The work rolls and the backup rolls are supported on a common rolling mill stand. The work rolls can be adjusted relative to each other in order to adjust a specified rolling gap. Each of the work rolls is operatively connected to at least one bending device. At least one first bending device is paired with die upper work roll, and at least one second bending device is paired with the lower work roll. The second bending device comprises bending cylinders which are arranged in a vertically fixed manner. The upper work roll can be readjusted or carried by the first bending device, thereby vertically adjusting die height of the rolling gap. The first bending device comprises bending arms that interact with bending cylinders arranged in a stationary manner.

Rolling device

A roll stand () with at least one upper and one lower roll () supported by respective backing rolls () mounted on a common roll frame () and in bearings that are vertically displaceable with respect to each other for setting different roll gaps, with at least one axial shifter for one of rolls () and with at least one bender comprising a bending cylinder () for bending the upper roll () is characterized in that the bender comprises horizontal traverses () and bending arms () at each ends of the upper roll (), whereby for setting the roll gap height between rolls () the roll () is guided by bending arms ().

Roll stand

The invention relates to a device for handling and/or transporting back-up rolls and/or work rolls () of a roll stand, preferably at least in pairs, especially in sets, between the roll stand arranged in a roll ball and a roll workshop, and in the roll workshop. Said device comprise a roll-changing pit that extends transversely to the roll direction of the roll stand, form the roll stand towards the roll workshop, and has displacement devices for at least one pair or set of dismantled back-up or work rolls (), and a roll-changing stand () that is arranged transversely to the roll-changing pit in the roll workshop and can be moved across said pit in or away from the roll direction of the roll stand. The aim of the invention is to enable the time required for a back-up roll change to be reduced and the back-up roll change to be simplified. To this end, the roll-changing stand () comprises two roll-receiving regions () that have an especially U-shaped cross-section and are arranged at a distance from each other in the roll direction of the roll stand, said regions each comprising both bearing surfaces () for receiving work rolls () and bearing surfaces () for receiving back-up rolls.

Device for handling and/or transporting back-up rolls and/or work rolls of a roll stand at least in pairs

The invention relates to a rolling device () comprising at least two working rolls () which are respectively mounted in a roll stand () by means of working roll assembly pieces (). At least one of the working rolls () is adjustable relative to the other working roll () within the roll stand (), especially in a vertical direction, so as to adjust a desired rolling gap. At east one working roll () is effectively connected to bending means (), with the aid of which said working roll () can be impinged upon by a bending moment. The working roll assembly piece () is provided with arms () that laterally protrude relative to the axis () of the working roll () to absorb the force generated by the bending means (). In order to improve the adjustability of the rolling device to a large ascent, a pressure-transmitting element () which can be displaced relative to the roll stand (), particularly in a vertical direction, is disposed between a pressure-generating element () of the bending means (), especially a piston, and the protruding arm () of the working roll assembly piece ().

Rolling stand

A rolling device with at least two rolls installed in a common stand, the rolls being mounted on lateral stringers by bearings, which are able to move vertically along the lateral stringers, and with at least one axial adjusting device for one of the rolls. The axial adjusting device is directly assigned to the vertically adjustable bearings and is able to move vertically along with them.
