Description

La présente invention est relative à un dispositif de régulation d'un débit de coulée, lequel dispositif comprenant un châssis métallique rectangulaire agencé pour pouvoir pivoter par rapport à une paroi de fond de la poche de coulée et un couvercle-poussoir contenant une plaque supérieure fixe et un chariot comprenant des moyens de guidage d'un tube de coulée appliqué contre une plaque mobile en contact étanche avec une plaque supérieure fixe, les deux plaques étant appuyées l'une contre l'autre par des dispositifs de pression appuyant chacune des plaques l'une contre l'autre, la plaque mobile et le tube de coulée pouvant être déplacés simultanément depuis une position d'ouverture du trou de coulée et vice-versa.The present invention relates to a device for regulating a flow rate, which device comprising a rectangular metal frame arranged to be able to pivot relative to a bottom wall of the ladle and a pusher cover containing a fixed upper plate and a carriage comprising means for guiding a pouring tube applied against a movable plate in leaktight contact with a fixed upper plate, the two plates being pressed against each other by pressure devices pressing each of the plates l 'one against the other, the movable plate and the pouring tube can be moved simultaneously from an open position of the tap hole and vice versa.

On connaît par le document EP-A-0202213 un châssis métallique pour dispositif de fermeture coulissante d'un conteneur métallurgique pour coulée continue comportant principalement une plaque de base solidaire du conteneur métallique et une porte pivotante articulée sur la plaque de base.Document EP-A-0202213 discloses a metal frame for a device for slidingly closing a metallurgical container for continuous casting, mainly comprising a base plate secured to the metal container and a pivoting door hinged on the base plate.

Dans ce document, le renouvellement d'éléments d'usure est grandement facilité par l'utilisation de fermetures coulissantes munies d'une ou de plusieurs portes articulées.In this document, the renewal of wear elements is greatly facilitated by the use of sliding closures provided with one or more hinged doors.

Les charnières de rotation amovibles et le dispositif de verrouillage amovible de la porte sur la plaque de base permettent d'accéder aisément aux pièces d'usure, à l'endroit même où est coulé l'acier. Un dispositif de prise de pression est prévu pour appliquer la plaque mobile contre la plaque fixe tandis que le tube de coulée est maintenu amoviblement contre la plaque mobile.The removable rotation hinges and the removable door locking device on the base plate allow easy access to the wearing parts, at the very place where the steel is poured. A pressure tapping device is provided for applying the movable plate against the fixed plate while the pouring tube is held removably against the movable plate.

Un inconvénient de ce dispositif connu réside dans le fait que la plaque mobile est enserrée entre deux éléments fixes. Une telle plaque mobile présente dès lors deux surfaces de glissement, la première face étant coulissante par rapport à la plaque supérieure du tube de coulée et la seconde par rapport à la plaque rapportée du tube de coulée.A drawback of this known device lies in the fact that the movable plate is sandwiched between two fixed elements. Such a movable plate therefore has two sliding surfaces, the first face being sliding relative to the upper plate of the pouring tube and the second relative to the added plate of the pouring tube.

On connaît aussi par le document WO-A 88/01211 un dispositif de fermeture coulissant d'un récipient de coulée par le fond comprenant un couvercle-poussoir maintenu en place par un châssis métallique monté pivotant par rapport à une paroi de fond du récipient de coulée afin de faciliter l'accès aux plaques réfractaires d'usure.Document WO-A 88/01211 also discloses a device for sliding closure of a bottom pouring container comprising a pusher cover held in place by a metal frame pivotally mounted relative to a bottom wall of the bottom container. casting to facilitate access to the refractory wear plates.

Le couvercle-poussoir contient une plaque supérieure fixe et un chariot portant un tube de coulée formant corps avec une plaque réfractaire mobile en contact avec la plaque supérieure fixe.The push cover contains a fixed upper plate and a carriage carrying a pouring tube forming a body with a movable refractory plate in contact with the fixed upper plate.

Pour obtenir une surface de coulissement parfaitement plane, la plaque supérieure est soumise à une rectification. Cette opération assure la planéité de la surface mais non pas une épaisseur constante ni précise de la plaque supérieure.To obtain a perfectly flat sliding surface, the upper plate is subjected to a correction. This operation ensures the flatness of the surface but not a constant or precise thickness of the upper plate.

L'insertion de la plaque supérieure dans le couvercle-poussoir nécessite une interruption prolongée de la séquence de coulée, lors du replacement de la plaque supérieure.The insertion of the upper plate into the push cover requires a prolonged interruption of the casting sequence, when replacing the upper plate.

La présente invention vise à réduire le nombre d'éléments d'usure en contact de glissement lors du réglage du débit et à améliorer l'amenée et l'échange d'un tube de coulée sous une poche de coulée ou sous un répartiteur de coulée sans être amené à modifier notablement la vitesse d'extraction de la brame, bloom ou billette.The present invention aims to reduce the number of wear elements in sliding contact when adjusting the flow rate and to improve the supply and exchange of a pouring tube under a tundish or under a tundish. without having to significantly modify the speed of extraction of the slab, bloom or billet.

Dans ce but, la présente invention propose un châssis articulé pour dispositif de régulation d'un débit de coulée permettant d'amener et d'échanger un tube de coulée tel que décrit dans le premier paragraphe du mémoire descriptif.To this end, the present invention provides an articulated frame for a device for regulating a flow rate making it possible to bring and exchange a pouring tube as described in the first paragraph of the description.

Le châssis articulé est essentiellement caractérisé en ce que les dispositifs de prise en pression susdits sont constitués de premiers et de seconds moyens de poussée, les premiers moyens de poussée étant des moyens de poussée vers le bas qui appliquent la plaque supérieure contre un plan de référence constitué par la plaque mobile et les seconds moyens de poussée étant des moyens de poussée vers le haut agissant sur des guides qui appliquent le tube de coulée contre la plaque mobile en position d'ouverture du trou de coulée.The articulated frame is essentially characterized in that the aforementioned pressure take-off devices consist of first and second pushing means, the first pushing means being down pushing means which apply the upper plate against a reference plane constituted by the movable plate and the second pushing means being upward pushing means acting on guides which apply the pouring tube against the movable plate in the open position of the taphole.

Selon une particularité de l'invention, le couvercle-poussoir est articulé sur le châssis métallique autour de seconds pivots.According to a feature of the invention, the push cover is articulated on the metal frame around second pivots.

Dans une forme de réalisation particulière, le dispositif de pression de la plaque supérieure fixe contre la plaque mobile est constitué de deux séries de cartouches à ressort disposées de part et d'autre du trou de coulée le long de côtés opposés de la plaque supérieure fixe.In a particular embodiment, the device for pressing the fixed upper plate against the movable plate consists of two series of spring cartridges arranged on either side of the taphole along opposite sides of the fixed upper plate .

Pour éviter leur chute lors de l'ouverture de la porte pivotante, les cartouches à ressorts sont retenues en place par une plaque de compression fixée amoviblement sur le couvercle poussoir à l'aide de plots.To avoid their fall when the pivoting door is opened, the spring cartridges are held in place by a compression plate fixed removably on the pusher cover using studs.

L'originalité du dispositif d'amenée et d'échange du tube de coulée selon l'invention réside dans le fait que le changement de tube se fait par glissement contre la face inférieure d'une plaque mobile formant un système de fermeture à tiroir à deux plaques, sans toutefois former un système à trois plaques tel que décrit notamment le brevet belge nr 896.223.The originality of the device for feeding and exchanging the pouring tube according to the invention lies in the fact that the tube change is made by sliding against the underside of a movable plate forming a drawer closing system with two plates, without however forming a three-plate system as described in particular in Belgian patent nr 896,223.

Le dispositif suivant l'invention offre l'avantage de rendre possible le réglage du débit d'acier par translation d'une partie mobile du dispositif de fermeture coulissante sans que le dispositif de changement de tube proprement dit ne bouge sous la plaque mobile. On évite ainsi toute détérioration du joint entre la plaque mobile et le tube de coule dû au frottement ou à l'infiltration de l'acier.The device according to the invention offers the advantage of making it possible to adjust the steel flow rate by translation of a movable part of the sliding closure device without the tube changing device itself moving under the movable plate. This avoids any deterioration of the joint between the movable plate and the pouring tube due to friction or the infiltration of steel.

Le ou les vérins pneumatiques ou hydrauliques qui exercent les efforts nécessaires au déplacement du tube de coulée en vue du changement de tube peut être directement fixé :

  • soit à une partie fixe de la machine;
  • soit au chariot mobile de la machine;
  • soit à un manipulateur extérieur, ne faisant pas partie intégrante de la machine.
The pneumatic or hydraulic jack (s) which exert the forces necessary to move the pouring tube for the purpose of changing the tube can be directly fixed:
  • either at a fixed part of the machine;
  • either to the mobile carriage of the machine;
  • either to an external manipulator, which is not an integral part of the machine.

Le déplacement du tube de coulée suivant un mouvement croisé, c'est-à-dire suivant deux directions perpendiculaires entre elles offre l'avantage de permettre la mise en oeuvre de premiers moyens d'entraînement rapides et de grande amplitude, mais peu précis pour l'amenée des tubes de coulée au voisinage immédiat du trou de coulée et des seconds moyens d'entraînement perpendiculaires aux premiers, de faible amplitude, mais très précis pour le réglage du débit.The displacement of the pouring tube in a crossed movement, that is to say in two directions perpendicular to each other, offers the advantage of allowing the implementation of first rapid drive means of large amplitude, but not very precise for bringing the pouring tubes in the immediate vicinity of the taphole and second drive means perpendicular to the first, of small amplitude, but very precise for adjusting the flow rate.

Ce mode de montage permet non seulement l'amenée et l'échange d'un tube de coulée, mais également le remplacement aisé des pièces d'usure tel que la plaque supérieure fixe ainsi que l'examen visuel de la busette interne.This mounting method not only allows the supply and exchange of a pouring tube, but also the easy replacement of wearing parts such as the fixed upper plate as well as the visual examination of the internal nozzle.

Dans ces figures, les mêmes signes de référence désignent des éléments identiques ou analogues.In these figures, the same reference signs designate identical or analogous elements.

Comme illustré dans la figure 1, un dispositif de fermeture coulissante 1 qui réalise l'amenée et l'échange d'un tube de coulée 2 et la régulation du débit d'une poche de coulée 3 comprend un châssis métallique rectangulaire 4 agencé pour pouvoir pivoter par rapport à une paroi de fond 5 de la poche de coulée 3 autour d'un de ses côtés par l'intermédiaire de premiers pivots horizontaux 6 disposés transversalement par rapport à la direction de déplacement de la plaque mobile 10 en vue de régler le débit de coulée. Les premiers pivots 6 sont engagés dans des pattes 30 fixées sur le fond de la poche de coulée 3.As illustrated in FIG. 1, a sliding closure device 1 which carries out and exchanges a pouring tube 2 and regulates the flow rate of a pouring bag 3 comprises a rectangular metal frame 4 arranged to be able pivot relative to a bottom wall 5 of the ladle 3 around one of its sides by means of first horizontal pivots 6 arranged transversely with respect to the direction of movement of the movable plate 10 in order to adjust the flow rate. The first pivots 6 are engaged in lugs 30 fixed on the bottom of the ladle 3.

Le châssis métallique 4 supporte un couvercle-poussoir 7 contenant une plaque supérieure fixe 8 et un chariot 9 portant la plaque mobile 10.The metal frame 4 supports a push cover 7 containing a fixed upper plate 8 and a carriage 9 carrying the movable plate 10.

La plaque supérieure 8 est appuyée vers le bas par un dispositif de pression 12 constitué de deux séries de cartouches à ressort 13, 14 disposées de part et d'autre du trou de coulée 15 le long de côtés opposés de la plaque supérieure fixe 8. Les cartouches à ressort 13, 14 sont retenues en place par les plots 17. Elles sont soumises à une précontrainte de compression, avant que le châssis 4 ne soit relevé et verrouillé.The upper plate 8 is pressed down by a pressure device 12 consisting of two series spring cartridges 13, 14 arranged on either side of the taphole 15 along opposite sides of the fixed upper plate 8. The spring cartridges 13, 14 are retained in place by the studs 17. They are subjected to a compression preload, before the chassis 4 is raised and locked.

La plaque mobile 10 est soumise à une poussée vers le bas transmise par la plaque supérieure fixe 8 repoussée vers le bas par une série de cartouches à ressort 13, 14 et elle est soumise aussi à une poussée vers le haut exercée par le tube de coulée, soumis à l'action des dispositifs de poussée 31, qui agissent indépendamment des cartouches 13, 14. La plaque mobile 10 est donc comprimée entre la plaque supérieure fixe 8 et une bride 11 du tube de coulée 2.The movable plate 10 is subjected to a downward thrust transmitted by the fixed upper plate 8 pushed down by a series of spring cartridges 13, 14 and it is also subjected to an upward thrust exerted by the pouring tube , subjected to the action of the pushing devices 31, which act independently of the cartridges 13, 14. The movable plate 10 is therefore compressed between the fixed upper plate 8 and a flange 11 of the pouring tube 2.

Au châssis métallique 4 est articulé le couvercle-poussoir 7 agencé pour pivoter vers le bas autour de seconds pivots horizontaux 18.The metal frame 4 is articulated with the push-cover 7 arranged to pivot down around second horizontal pivots 18.

Le chariot 9 comprend des moyens de guidage 19, 20 du tube de coulée 2 dressé verticalement. Les moyens de guidage 19, 20 s'étendent dans un plan horizontal. Ils amènent le tube de coulée 2 de remplacement depuis une position de chargement 21 située loin du trou de coulée vers une position d'attente 22 située juste en-dessous de l'orifice de coulée 27 de la plaque mobile 10 au moment où celle-ci se trouve en position d'obturation du trou de coulée. Les moyens de poussée 31 sont repoussés vers le haut par des leviers 35 articulés en 36 et soumis à l'action de ressorts 37 à leur extrémité libre 38.The carriage 9 comprises guide means 19, 20 of the pouring tube 2 erected vertically. The guide means 19, 20 extend in a horizontal plane. They bring the replacement pouring tube 2 from a loading position 21 located far from the tap hole to a standby position 22 located just below the pouring orifice 27 of the movable plate 10 when the latter this is in the closed position of the tap hole. The pushing means 31 are pushed upwards by levers 35 articulated at 36 and subjected to the action of springs 37 at their free end 38.

Dans la figure 1, les premiers et seconds pivots 6, 18 sont parallèles entre eux. Ils déterminent un axe de rotation L L' perpendiculaire à la direction du déplacement selon la flèche X du tiroir à deux plaques formé par la plaque supérieure fixe 8 et la plaque mobile 10 lors de la régulation du débit d'acier.In Figure 1, the first and second pivots 6, 18 are parallel to each other. They determine an axis of rotation L L 'perpendicular to the direction of movement along arrow X of the two-plate drawer formed by the fixed upper plate 8 and the movable plate 10 during the regulation of the steel flow rate.

Le châssis 4 doublement articulé facilite tout simplement l'accès aux pièces réfractaires, notamment à la plaque mobile 10.The doubly articulated chassis 4 simply facilitates access to the refractory parts, in particular to the movable plate 10.

Le montage et le démontage du châssis articulé 4 d'un dispositif d'amenée et d'échange d'un tube de coulée 2 et de régulation d'une poche de coulée 3 sur la paroi de fond 5 d'une poche de coulée 3 s'effectue comme suit.The assembly and disassembly of the articulated frame 4 of a device for supplying and exchanging a pouring tube 2 and regulating a pouring bag 3 on the bottom wall 5 of a pouring bag 3 is as follows.

Pour le montage, on positionne une busette interne 23 dans une brique de siège 24 de la poche de coulée 3 par le dessous. On dispose un joint 25 sur la bride inférieure débordante de la busette interne 23 et on enduit le joint 25 d'un mastic réfractaire avant d'emboîter dans l'extrémité inférieure de la busette interne 23 une languette tronconique 37 d'une plaque supérieure 8.For mounting, an internal nozzle 23 is positioned in a seat brick 24 of the ladle 3 from below. There is a seal 25 on the lower flange projecting from the internal nozzle 23 and the seal 25 is coated with a refractory sealant before fitting into the lower end of the internal nozzle 23 a frustoconical tongue 37 of an upper plate 8 .

On retient en place deux séries 13, 14 de cartouches à ressort à l'aide d'une plaque de compression 16 fixée amoviblement à la plaque supérieure 8 à l'aide de plots 17. Pour fixer la plaque de compression 16 au couvercle-poussoir 7, on comprime des cartouches à ressort 13, 14 à l'aide d'un outillage hydraulique non montré en s'appuyant sur la plaque de compression 16 et on verrouille la plaque de compression 16 à l'aide de pièces d'ancrage comportant un écrou à oreilles 40. En relâchant l'outillage hydraulique, on libère la plaque supérieure.Two series 13, 14 of spring cartridges are retained in place using a compression plate 16 fixed removably to the upper plate 8 using studs 17. To fix the compression plate 16 to the push cover 7, spring cartridges 13, 14 are compressed using a hydraulic tool not shown by pressing on the compression plate 16 and the compression plate 16 is locked using anchoring parts comprising a wing nut 40. By releasing the hydraulic tools, the upper plate is released.

On ferme la machine, en rabattant dans le sens horlogique le couvercle-poussoir 7 sur le châssis métallique 4 et en rabattant le chassis métallique 4 dans le sens anti-horlogique contre la paroi de fond 5 de la poche de coulée 3. Ce verrouillage du châssis métallique 4 s'effectue par basculement des vis à oeil 26 dans une encoche 41 du châssis métallique 4. Le vérin hydraulique est fixé au chariot mobile par un goujon introduit dans le trou 28 ménagé dans la patte d'arrimage 29 du chariot 9.The machine is closed by folding the push cover 7 clockwise on the metal frame 4 and by folding the metal frame 4 anti-clockwise against the bottom wall 5 of the ladle 3. This locking of the metal chassis 4 is effected by tilting the eye screws 26 in a notch 41 of the metal chassis 4. The hydraulic cylinder is fixed to the movable carriage by a stud inserted in the hole 28 formed in the lug 29 of the carriage 9.

Le démontage du dispositif d'amenée et d'échange d'un tube de coulée et de régulation du débit s effectue dans l'ordre inverse du montage :

  • basculement des vis à oeil 26 fixant le châssis métallique rectangulaire 4 à la paroi de fond 5 de la poche de coulée 3;
  • ouverture de la machine en position verticale;
  • compression des cartouches à ressort à l'aide d'un outillage hydraulique non montré prenant appui sur la plaque de compression 16;
  • déblocage des écrous à oreilles 40 fixant le couvercle-poussoir 7 au châssis métallique rectangulaire 4;
  • déserrage des vis 32;
  • ouverture du couvercle-poussoir 7;
  • déserrage des vis de verouillage 33, 34 de la plaque supérieure fixe 8 et de la plaque mobile 10;
  • démontage de la plaque supérieure fixe 8 et de la plaque mobile 10.
The disassembly of the supply and exchange device for a pouring and flow regulation tube is carried out in the reverse order of assembly:
  • tilting of the eye screws 26 fixing the rectangular metal frame 4 to the bottom wall 5 of the ladle 3;
  • opening of the machine in vertical position;
  • compression of the spring cartridges using a hydraulic tool not shown bearing on the compression plate 16;
  • release of the wing nuts 40 fixing the push cover 7 to the rectangular metal frame 4;
  • loosening of the screws 32;
  • opening the push cover 7;
  • loosening the locking screws 33, 34 of the fixed upper plate 8 and of the movable plate 10;
  • disassembly of the fixed upper plate 8 and of the movable plate 10.
