Definitions

  • Refractory plate for a device for the insertion and/or removal of a nozzle for a casting installation combined with a sliding plate flow-control device.
  • the present invention relates to a refractory plate for a device for the insertion and/or removal of a nozzle for a casting installation combined with a sliding plate flow-control device.
  • the casting of a melt is generally carried out with an installation comprising several refractory elements forming a casting channel between two consecutive metallurgical containers. These elements fulfill different functions which are the transfer of the melt, the protection of the melt against cooling and the chemical attacks of the surrounding atmosphere and, optionally, the control of the melt casting flow.
  • the melt contained in a casting ladle is poured through a discharge orifice arranged in the bottom wall of the ladle and prolonged by a nozzle extending through the bottom wall.
  • a device for the flow-control of the liquid metal stream Under the bottom wall, there is generally a device for the flow-control of the liquid metal stream, the device being constituted from refractory plates provided each with a casting orifice which can be aligned or shifted one with respect to the other by the relative displacement of the plates so as to modify the cross-sectional flow area defined by the superposition of the pouring orifices.
  • the melt exits from the flow-control device into a nozzle, having generally a small length and called collector nozzle.
  • collector nozzle having generally a small length and called collector nozzle.
  • a casting tube intended for shrouding the stream discharged from the collector nozzle during its way to a tundish is provided. Conventionally, this shroud is fitted on the downstream end of the collector nozzle.
  • the nozzle can be formed of several adjacent elements, in particular, an inner nozzle ending upstreamly with the pouring orifice arranged in the bottom wall and downstreamly with an end formed as a plane surface and a subentry nozzle ending upstreamly with a plane surface matching the plane surface of the inner nozzle.
  • an appropriate device such as described for example in the patent EP-A1- 192,019
  • the flow- control of the melt poured from the tundish is performed with a stopper system which can close the pouring orifice arranged in the bottom wall.
  • the present invention relates more particularly to an installation comprising a device for the insertion and/or removal of a nozzle for a casting installation combined with a sliding plate flow- control device.
  • the lower plate of the sliding plates flow-control device is also the stationary plate of the device for the insertion and/or removal of a nozzle for a casting installation combined with a sliding plate flow-control device against which the nozzle is brought from an insertion position towards a casting position by the device for the insertion and/or removal.
  • the plate is not enough supported into its housing, the plate is indeed not homogeneously supported.
  • the pressure is not uniformly distributed around the pouring orifice of the plate and an incident called "finning" consisting in the formation of a thin strip of frozen metal between the stationary plate and the mobile plate, can take place. If this incident occurs repeatedly, the frozen metal strip acts as a wedge and push apart the two plates. It can even end with an infiltration of molten metal which cause the immediate termination of the casting operations.
  • the guiding surface is not sufficient to permit a correct guiding of the nozzle from the introduction position towards the casting position, the risk to have this casting nozzle in an incorrect position is important with all the adverse consequences that one can imagine.
  • the refractory plates have as low as possible dimensions, in, in particular as to its thickness.
  • the casting channel extending through the lower pate of the sliding plate flow-control device is subjected to a very strong erosion due to the turbulent and asymmetrical molten metal stream passing through it.
  • the inventors have thus seek to solve these problems and have come to the idea of providing the plate in question with a protuberance.
  • FIG. 1 shows top views of two different refractory plates according to the invention.
  • Figures 2 and 2a show to cross-sectional views according to the line A-A respectively of figure 1 and 1a.
  • Figure 3 shows a cross-sectional view according to the line B-B of figure 1.
  • Figures 4 and 4a show perspective views from the lower face of the plates respectively of figure 1 and 1a.
  • the refractory plate for a device for the insertion and/or removal of a nozzle for a casting installation combined with a sliding plate flow-control device comprises the following elements: a) a first surface (1 ) provided with an orifice (2) defining the entry of a casting channel (3) through the plate and able to form a sealing surface, at least around the orifice (2), with a face matching the face of a mobile plate of the flow-control device; b) a second surface (4) adapted to rest in housing of the device and provided with a plane protuberance (5) circumscribing the casting channel (3) and extending through the bottom wall of the housing, and c) a third surface (6) defined by the plane surface of the protuberance (5) provided with an orifice (7) defining the exit of the casting channel (3) through the plate. It is essential that the surface (6) be adapted
  • the preferred shape for the protuberance is a tip shape, the tip (8) being directed towards the introduction position of the refractory tube.
  • the initial efforts required to move the tube from its introduction position are quite low and increase progressively as the tube moves closer to its casting position.
  • this particular shape allows an adjustment of the tube during its progression in the device.
  • Particularly suitable shape are the oval, triangle, or egg shapes.
  • the egg shape (see on the figures 1 , 1a, 4 and 4a) permitting to avoid sharp angles and maximizing the above described effect is particularly preferred.
  • the tip according to the invention can or not be provided with a metallic envelope.
  • a second passage (12) extending through the plate from an orifice (11 ) of the third surface (6) towards an orifice (13) of the first surface (1) is provided.
  • this second passage (12) will have smaller dimension than the casting channel (3) and will be localized far from the casting channel (3), for example close to the end of the tip (8).
  • This embodiment is depicted on figures 1a, 2a and 4a.

Abstract

L'invention concerne une plaque réfractaire pour un dispositif servant à insérer et/ou extraire une buse dans une installation de moulage combinée à un dispositif de réglage de débit à lame coulissante, ladite plaque comprenant a) une première surface (1) dotée d'un orifice (2) qui définit l'entrée du canal de coulée (3) à travers la plaque et forme une surface d'étanchéité au moins autour de l'orifice (2), une face correspondant à la face d'une plaque mobile du dispositif de réglage de débit; b) une deuxième surface (4) conçue pour prendre appui dans le boîtier du dispositif et pourvue d'une protubérance plane (5) limitant le canal de coulée (3) et traversant le fond du boîtier, et c) une troisième surface (6) délimitée par la surface plane de la protubérance (5) dotée d'un orifice (7) définissant la sortie du canal de coulée (3) à travers la plaque. Cette dernière surface (6) est conçue pour former une surface d'étanchéité au moins autour de l'orifice (7), correspondant à une face d'un tube réfractaire en position de coulée, et pour servir de surface de guidage au tube réfractaire pour passer d'une position d'introduction à une position de coulée. La plaque réfractaire est façonnée de telle sorte que la partie de la troisième surface (6) en contact avec la face correspondante du tube réfractaire augmente à mesure que le tube se déplace de la position d'introduction à la position de coulée. Ladite plaque réfractaire offre un compromis optimal entre la nécessité d'un soutien maximum dans la partie inférieure de la plaque et la maximisation de la surface inférieure disponible pour guider le tube de la position d'introduction à la position de coulée.
