Definitions

  • the invention relates to a method and a device for operating a rolling mill, in particular a strip rolling mill with, for example, a plurality of duo or four-high rolling stands connected in series, in which at least one positioning means provided on the side of the axis plane of the rolls is assigned to identical chocks on both sides of the roll gap. with which, prior to the occurrence of rolling force, the chocks of the rollers are pressed against the stator side lying in the direction of the transverse component from the rolling force without play.
  • the play between chocks and the associated window opening required for the roll change during rolling is to be eliminated in order to avoid an undefined position of the rolls due to the necessary lateral play, for example a crossing position , to avoid.
  • the object of the invention is to make those chocks of a rolling mill free of play before rolling in the direction of the transverse component from rolling force which have to perform adjusting movements influenced by a roll gap control during rolling.
  • the solution to this problem in terms of process technology according to the invention is that the actuating means are arranged in the roller stand and in duo-rollers with its chocks, but in the four-high mill stand with the chocks of the support rollers in connection, and that the adjusting means are the aforementioned chocks with side faces of the Bring the stand window directly to the system, the actuating cylinders being depressurized during the rolling process and the aforementioned chocks being held in this defined position solely by the force obtained from the rolling process.
  • a roll stand in which the known actuating cylinders are arranged in the roll stand and act on the chocks of duo rolls or of support rolls serves as the device for carrying out the method according to the invention.
  • each of the chocks 3 of the support rollers 2 are assigned and when loaded with their pistons 8, which then protrude into the stator window 6, until they press against the chocks until they rest against the actuating cylinders 7 opposite side surfaces 6a of the roller stand 1 or the stator window 6.
  • the transverse component of rolling force for the support roller chocks 3 is directed to the right in the specified rolling direction from right to left in a four-high roll stand, it is the side surfaces 6a arranged on the inlet side against which the support roller chocks 3 are brought into contact.
  • the pistons 8 of the actuating cylinders are retracted, after which the chocks 3 are held against the side surfaces 6a during rolling exclusively by the force obtained from the rolling force, so that the chocks can be freely adjusted under the influence of a roll gap control under usual conditions are.

1. Procédé pour le fonctionnement d'un laminoir de bande et plus spécialement d'un laminoir comprenant notamment plusieurs cages de laminoirs quarto ou duo montées les unes après les autres et comportant des empoises du même type des deux côtés de la fente de laminage, pourvues d'au moins un dispositif de réglage (7) placé latéralement par rapport au plan des axes des cylindres, et à l'aide duquel on immobilise sans jeu les empoises des cylindres avant l'apparition de la force de laminage, en les poussant contre la face du montant de la cage vers laquelle est dirigée la composante transversale de la force de laminage, caractérisé en ce que les dispositifs de réglage (7) sont logés dans les montants (1) de la cage de laminoir et ils sont en liaison avec les empoises des cylindres d'un laminoir duo ou avec les empoises (3) des cylindres d'appui (2) dans le cas d'un laminoir quarto et en ce que les dispositifs de réglage (7) amènent lesdites empoises en appui direct contre des surfaces latérales (6a) de la fenêtre (6) de la cage, si bien que, pendant le développement de l'opération de laminage, les vérins de réglage (7) sont mis hors pression et les empoises précitées sont maintenues dans la position définie de la sorte uniquement par la force obtenue à partir du processus de laminage.
2. Dispositif pour la mise en oeuvre du procédé suivant la revendication 1 comprenant une cage de laminoir dans laquele des empoises d'un même type sont placées des deux côtés de la fente de laminage et au moins un vérin de réglage (7) est monté latéralement par rapport au plan des axes des cylindres de laminage, caractérisé en ce que les vérins (7) sont logés dans les montants (1) du laminoir et ils agissent sur les empoises des cylindres de laminage duo ou les cylindres d'appui.
