Definitions

  • the invention relates to a rolling device with at least one upper and lower work roll and with at least one upper and one lower back-up roll, the work rolls and the back-up rolls being mounted in a common roll stand, the work rolls being adjustable relative to one another to set a predetermined roll gap and the work rolls each are operatively connected to at least one bending device, wherein at least one first bending device is assigned to the upper work roll and at least one second bending device is assigned to the lower work roll, the second bending device comprises bending cylinders which are arranged vertically in a stationary manner and the upper work roll is connected by means of the first bending device to a vertical adjustment of the height of the roll gap can be adjusted or carried along.
  • a rolling device of the type described above is for example from EP 2 342 026 B1 known.
  • the EP 2 342 026 B1 describes a rolling device with work roll bending and balancing cylinders.
  • the bending cylinders for the lower work roll are arranged vertically in stationary blocks.
  • the bending device for the upper work roll is characterized by bending arms which are vertically displaceable in guides on the roll stand.
  • the bending cylinders are guided within the window of the roll stand below its crosshead on balancing arms of the upper support roll via crossbeams on balancing arms. This means that when the upper rolls are positioned, they are moved together with the support roll balancers.
  • the chocks of the upper work roll are subjected to a vertical force via the bending arms, which are suspended in the crossbeams.
  • a work roll - axial shifting and bending device is provided with which a very high rolling gap of up to about 1100 mm can be realized.
  • the work rolls - axial shifting and bending device described - has the disadvantage that when the upper bending cylinder is actuated to influence the roll gap contour, interactions with the upper back-up roll balancing can occur. At the very least, it is necessary to make the cylinder of the upper back-up roll balancing significantly stronger so that no negative effects can be caused on the roll gap contour.
  • the components that are arranged in the power flow with the upper support rollers - balancing must be designed to absorb relatively high forces.
  • JPS5680308 A which forms the basis for the preamble of claim 1, is known as a rolling device with at least one upper and one lower work roll and with at least one upper and one lower back-up roll, the work rolls and the back-up rolls being mounted in a common roll stand, the work rolls for setting a predetermined roll gap are adjustable relative to each other and the work rolls are each in operative connection with at least one bending device, wherein at least one first bending device is assigned to the upper work roll and at least one second bending device is assigned to the lower work roll, the second bending device comprises bending cylinders which are vertically stationary and the upper work roll can be adjusted or carried along by means of the first bending device with a vertical adjustment of the height of the roll gap, the first bending device having bending cylinders arranged in a stationary manner.
  • the invention is based on the object of providing a roll stand of the type mentioned at the outset, which enables a very high roll gap and thereby avoids undesirable interactions with the back-up roll balancing.
  • the invention is based on the object of realizing a work roll bending device on a roll stand of the type mentioned at the outset, which enables good guidance of the work roll chocks in the stand window with maximum to minimum roll diameters and with maximum and minimum roll gap.
  • the advantages described above should also be able to be realized in a rolling device with a work roll axial displacement device.
  • a rolling device is provided with at least one upper and one lower work roll and with at least one upper and one lower back-up roll, the work rolls and the back-up rolls being mounted in a common roll stand, the work rolls being adjustable relative to one another to set a predetermined roll gap and the work rolls are each operatively connected to at least one bending device, a first bending device being assigned to the upper work roll and a second bending device being assigned to the lower working roll, the second bending device comprising bending cylinders which are arranged in a vertically stationary manner and the upper working roll being adjusted by means of the first bending device for vertical adjustment of the height of the roll gap between the rolling passes can be adjusted or carried along.
  • the rolling device according to the invention is characterized in particular by the fact that the first bending device comprises bending arms which interact with stationary bending cylinders.
  • a bending arm in the context of the invention is to be understood as a connecting element which bridges a spatial separation from the bending cylinder to the point at which the bending force acts on the work roll chocks. Due to the structural and spatial separation of the first bending device from the second bending device, a particularly high roller gap of at least 900 mm, preferably 1200 mm, particularly preferably 1350 mm, can be made possible.
  • the stroke of the first bending device follows the travel of the vertical adjustment of the Height of the roll gap to ensure contact between the top work roll and the top back-up roll for rolling.
  • the first bending device is structurally separate from a roll adjustment.
  • the bending device for the upper work roll is essentially decoupled from a balancing system for the upper backup roll.
  • the decoupling simplifies the accessibility of the two devices for maintenance purposes.
  • the bending arms of the first bending device carry the upper work roll along when the height of the roll gap is adjusted vertically.
  • the height of the roll gap is preset before the start of rolling (roll pass). For this purpose, an overhead roller adjustment moves the upper back-up roller to the position in which it is held by the back-up roller balancing against the force of weight.
  • the upper work roll follows this vertical movement, supported by the arms of the bender.
  • the bending cylinders and thus also the upper work roll initially follow the movement of the upper back-up roll between the rolling passes.
  • An additional stroke of the bending cylinder causes bending of the work roll and thus the desired influence on the contour of the roll gap during the pass.
  • the work rolls can be adjusted axially and vertically.
  • the stationary mounting of the bending cylinders of the first, upper bending device is particularly advantageous in connection with an axial adjustment of the work rolls, because the structurally and spatially separate back-up roll balancing in this arrangement is not additionally subjected to the reaction forces resulting from the bending of the work rolls.
  • At least one axial displacement device is preferably provided for at least one of the work rolls.
  • the axial displacement device for example the upper work roll, can be arranged stationary on the roll stand or can be overhung.
  • At least one axial displacement device is operatively connected to the bending arms of the first bending device.
  • the operative connection can be accomplished via a direct connection between bending arms and axial displacement. Indirect connections, for example via other bolts or guides, also ensure an active connection.
  • the bending cylinders of the second bender may be arranged vertically in stationary blocks and act on work roll chocks of the lower work rolls.
  • the bending cylinders of the second bending device are arranged in thickenings of a roll stand of the roll stand.
  • the bending cylinders of the first bending device i. H. the bending device, which entrains the upper roll arrangement (upper work roll and upper back-up roll), in each case on an upper crosshead of a roll stand of the roll stand.
