Definitions

  • the invention relates to a strand guide, in particular for the production of slabs with support spacings that can be adjusted to different strand thicknesses.
  • Strand guides on continuous casting plants with mutually opposite frame or scaffold parts connected by tie rods, on which strand guide rollers are mounted, are known from DE 26 12 094 A1.
  • the invention is based on the object of designing the strand guide such that, in particular when casting thin slabs in the partially solidified region, it is possible to set guide rollers in three defined positions.
  • the device according to the invention realizes the requirements that two positions are adjustable by the upper and lower position of the hydraulic differential cylinder and the third position is possible by including the additional, integrated hydraulic plunger cylinder.
  • a strand deformation with a liquid core from the initial format of the mold is first carried out to an intermediate dimension in the first segment of the strand guide downstream of the mold.
  • the following strand guides are permanently set to this intermediate dimension by means of the step plate.
  • rollers 12 are held on roller bearings 13 on an upper frame 1 and a lower frame 2.
  • Upper frame 1 and lower frame 2 are connected to one another via a piston-cylinder unit 4, 5.
  • the piston rod 5 is fastened to the bearing mounting 8 with a spherical bearing 6 on the upper frame 1 and the cylinder 4 via the spherical bearing 7 on the lower frame 2.
  • a spacer 9 is arranged between the upper frame 1 and a side frame 3 in the power flow of the piston-cylinder unit 4, 5.
  • Fig. 2 shows a basically similar structure of the device.
  • the spacer 9 is designed in a manner known per se as a stepped disk, surrounds the piston rod 5 and lies against a support surface 14 of the upper frame 1.
  • a hydraulic plunger cylinder 10, 11 is arranged between the spacer 9 and the side frame 3.
  • the travel of the annular piston 11 is designated by "X”.
  • the short-stroke hydraulic plunger cylinder is shown in the extended position. This position defines the largest distance between a pair of rollers and corresponds to the position when cast on until the cold strand head passes.
  • the pressure force in the hydraulic plunger cylinder 10, 11 must be increased in such a way that the tensile force exerted by the piston-cylinder unit 4, 5 on the two frame parts 1, 2 is overcome.
  • the hydraulic plunger cylinder is relieved of pressure, so that the travel "X" is reduced to zero. In this position, the amount of deformation of the cast strand is also determined.

  1. Guide de barre sur des installations de coulée continue pour engendrer des brames, en particulier selon le procédé de laminage de coulée continue, comportant des rouleaux opposés par paire et réglables à différentes épaisseurs de barre, qui sont montés sur des parties de cage ou de bâti reliées par des tirants d'ancrage et dont les tirants d'ancrage sont formés par des vérins, et, dans l'emprise du vérin, des pièces d'écartement sont disposées entre des parties de bâti supérieure et inférieure,
    caractérisé par un vérin annulaire hydraulique (10,11) agencé entre la pièce d'écartement (9) et le cylindre (4) du vérin (4,5), qui entoure la tige de piston (5) et dont le piston annulaire (11) porte, par adhérence, la pièce d'écartement (9), et le piston annulaire (11) est réglable sur une course de réglage (X) qui s'étend d'une position dans l'état déchargé en pression, dans lequel les parties de cage (1,2) sont réglées à une distance des rouleaux (12), qui correspond à l'épaisseur de barre souhaitée pendant la coulée, vers une position dans l'état chargé en pression, dans lequel les parties de cage (1,2) sont réglées à une distance des rouleaux (12), qui correspond à l'épaisseur de tête de la barre froide.
  2. Guide de barre selon la revendication 1,
    caractérisé en ce que les vérins annulaires hydrauliques (10,11) sont appuyés sur des bâtis latéraux (3), et les bâtis latéraux (3) relient au moins deux sous-cadres (2) en un segment du guide de barre.
