Definitions

  • the invention relates to a bending and Ausbalanciervorraum for axially movable work rolls of a rolling stand, in particular a four-high stand, with guide blocks in the height range of the work roll chocks are provided on both sides in the window of each roll stand and transmit the force of bending and Balancierzylindern on the axially and vertically displaceably guided work roll chocks ,
  • Such rolling mills can be present in hot and cold rolling mills, Steckel mills and plate rolling mills.
  • the object of the invention is to provide a bending and balancing device which ensures a much larger work roll entrance while constant, maximum guidance of the work roll chocks.
  • the flying negative and / or positive bending device including balancing function for stationary and axially displaceable work rolls, is thus particularly suitable for high rises.
  • the core idea of the solution according to the invention is that the previous one-piece stationary guide block is divided into an upper movable guide block and a lower fixed or movable guide block.
  • a bending and Balancierzylinder Arranged in or connected to the upper or lower guide block is a bending and Balancierzylinder which acts simultaneously on the upper and lower work roll and is guided in the respective other guide block.
  • the upper movable guide block or both movable guide blocks are guided in the roll stand.
  • a negative bending of the work rolls can be realized in that the pressure cover the work roll construction tail pipes or the guide blocks clasp the work roll mounting lugs form fit.
  • the invention combines the high reliability of the present bending and balancing device design with greater flexibility with respect to increasing the nip.
  • Another advantage is that according to the invention with a minimum number of bending and Balancierzylinder manages for positive and negative bending, by the simultaneous action on the lower and upper work roll.
  • the invention allows a larger adjustment range of the work roll bending (positive and negative), the z for special process requirements.
  • the work roll chocks 3 and 3 'for the upper and lower work rolls 10 and 10' are indicated.
  • the guide block divided according to the invention is fastened to the window, the upper guide block 2 being movable and the lower guide block 2 'likewise being movable or stationary.
  • FIG. 3 In the execution after FIG. 3 is - in adaptation to performance FIG. 1 - Only exchanged the piston assembly.
  • the guide block 2 clasps the approach of the work roll chock 3 or Druckdeckelerweiterept 7 clasp the ears of the work roll chocks 3 and 3 ', so that the movement of the bending and Balancierzylinders is directly transferable in both directions.

    - les blocs de guidage sont chaque fois subdivisés en un bloc de guidage supérieur (2) et en un bloc de guidage inférieur (2') ;
    - les blocs de guidage supérieurs (2) sont montés dans la fenêtre de la cage de laminoir (1) de manière à pouvoir se déplacer en direction verticale ;
    - les blocs de guidage inférieurs (2') sont montés dans la fenêtre de la cage de laminoir (1) en immobilité ou également de manière à pouvoir se déplacer en direction verticale ; et
    - dans chacun des blocs de guidage supérieurs et inférieurs (2, 2') pris ensemble, est disposé un cylindre de flexion et d'équilibrage (5) guidé par ces derniers, qui entre en engrènement avec l'empoise supérieure (3) et l'empoise inférieure (3') de cylindre de travail ;
    - des dispositifs de déplacement (6) pour le déplacement axial des empoises de cylindres de travail (3, 3'), y compris le verrouillage (9) des cylindres de travail, sont disposés contre le bloc de guidage supérieur et le bloc de guidage inférieur ;
    - le transfert de force des cylindres de flexion et d'équilibrage (5) aux empoises de cylindres de travail a lieu via des couvercles résistant à la pression (4, 4', 7') disposés en position adjacente aux dernières citées, respectivement via les blocs de guidage ; les couvercles résistants à la pression (4, 4'), respectivement les extensions des couvercles résistants à la pression (7) enserrent par complémentarité de forme des oreilles des empoises de cylindres de travail, ou bien les blocs de guidage (2, 2') enserrent des épaulements des empoises de cylindres de travail (3, 3').
