Description

La présente invention est relative à un dispositif de régulation d'un débit de coulée continue sous une poche de coulée, lequel dispositif comprend un couvercle-poussoir contenant une plaque supérieure fixe et monté sur un châssis métallique rectangulaire, agencé pour pivoter par rapport à une paroi de fond de la poche de coulée et portant un chariot muni de moyens de guidage d'un tube de coulée appliqué contre une plaque mobile en contact étanche avec la plaque supérieure fixe, les deux plaques étant appuyées l'une contre l'autre par des dispositifs de pression, la plaque mobile et le tube de coulée pouvant être déplacés simultanément depuis une position d'obturation vers une position d'ouverture du trou de coulée et vice-versa.The present invention relates to a device for regulation of a continuous flow rate under a ladle casting, which device comprises a push cover containing a fixed upper plate and mounted on a frame rectangular metal, arranged to pivot relative to a bottom wall of the ladle and carrying a carriage provided with means for guiding a pouring tube applied against a movable plate in tight contact with the upper plate fixed, the two plates being pressed against each other by pressure devices, the moving plate and the tube casting can be moved simultaneously from one position shutter to an open position of the tap hole and vice versa.

On connaít 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.We know from document EP-A-0202213 a metal frame for sliding closure device a metallurgical container for continuous casting mainly comprising a base plate integral with the metal container and a pivoting door articulated 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 elements wear is greatly facilitated by the use of closures sliding doors with one or more doors articulated.

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.Removable rotation hinges and device removable door lock on the plate base allow easy access to parts wear, at the same place where the steel is poured. A device pressure tap is provided to apply the plate movable against the fixed plate while the tube casting is held removably against the plate mobile.

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 disadvantage of this known device lies in the fact that the movable plate is clamped between two elements fixed. Such a movable plate therefore has two sliding surfaces, the first face being sliding relative to the top plate of the tube of casting and the second in relation to the added plate of the pouring tube.

On connaít 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.We also know from document WO-A 88/01211 a sliding closure device for a container bottom pouring including a push cover held in place by a mounted metal frame pivoting relative to a bottom wall of the container casting to facilitate access to the refractory plates wear.

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 top plate fixed and a carriage carrying a pouring tube forming 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 sliding surface flat, the top plate is subjected to a rectification. This operation ensures the flatness of the surface but not constant or precise thickness of the top 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.Inserting the top plate into the push cover requires prolonged interruption of the casting sequence, when replacing the plate higher.

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 wear elements in sliding contact during adjusting the flow and improving the supply and exchange of a pouring tube under a ladle or under a flow distributor without having to modify notably 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 a articulated frame for flow control device pouring to bring and exchange a tube as described in the first paragraph of the descriptive memory.

Le châssis articulé est essentiellement caractérisé en ce que les dispositifs de pression 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 de moyens de poussée vers le haut agissant indépendamment des moyens de poussée vers le bas, sur des guides qui appliquent le tube de coulée contre la plaque mobile, en suivant le déplacement de la plaque mobile entre ses positions d'obturation et d'ouverture du trou de coulée.The articulated chassis is essentially characterized in that pressure devices consist of prime and second pushing means, the first pushing means being downward pushing means which apply the upper plate against a reference plane constituted by the movable plate and the second thrust means being of upward pushing means acting independently of means of pushing down, on guides which apply the pouring tube against the movable plate, following the movement of the movable plate between its closed positions and opening the tap hole.

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 pressure of the fixed upper plate against the movable plate consists of two series of cartridges spring loaded on either side of the hole pouring along opposite sides of the top plate fixed.

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 prevent them from falling when the door is opened pivoting, the spring cartridges are retained in place by a removable removable compression plate 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 supply and exchange system pouring tube according to the invention resides in the fact that the tube change is done by sliding against the underside of a movable plate forming a system drawer closure with two plates, without however forming a three-plate system as described in particular 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 make it possible to adjust the steel flow by translation a movable part of the sliding closure device without the tube changing device itself does not move under the movable plate. We thus avoids any deterioration of the joint between the plate mobile and the sinking tube due to friction or infiltration 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'entraínement 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'entraínement perpendiculaires aux premiers, de faible amplitude, mais très précis pour le réglage du débit.The displacement of the pouring tube following a movement crossed, i.e. in two perpendicular directions between them has the advantage of allowing the implementation of first means of training fast and large, but imprecise for bringing the pouring tubes in the immediate vicinity of the tap hole and second drive means perpendicular to the first, of small amplitude, but very precise for adjusting the flow.

    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 the exchange of a pouring tube, but also easy replacement of wearing parts such as the plate fixed upper as well as visual examination of the internal nozzle.

    Ces particularités et d'autres particularités et détails de l'invention ressortiront de la description suivante des dessins schématiques ci-annexés qui représentent à titre illustratif une forme de réalisation de l'invention.These peculiarities and other peculiarities and details of the invention will emerge from the following description attached schematic drawings which represent for illustrative purposes an embodiment of the invention.

    Dans ces figures, les mêmes signes de référence désignent des éléments identiques ou analogues.In these figures, the same reference signs denote 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 Figure 1, a closing device sliding 1 which carries out the supply and the exchange of a pouring tube 2 and the regulation of the flow of a ladle 3 includes a rectangular metal frame 4 arranged to be able to pivot relative to a bottom wall 5 of the ladle 3 around a on its sides by means of the first horizontal pivots 6 arranged transversely to the direction of movement of the movable plate 10 within sight to regulate 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 of spring cartridges 13, 14 arranged on either side tap hole 15 along opposite sides of the plate fixed upper 8. Spring cartridges 13, 14 are retained in place by the studs 17. They are subject 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 thrust downwards transmitted by the fixed upper plate 8 pushed down by a series of cartridges to spring 13, 14 and it is also subjected to a thrust upwardly exerted by the pouring tube, subjected to the action of the pushing devices 31, which act independently of the cartridges 13, 14. The plate mobile 10 is therefore compressed between the upper plate fixed 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 push-button cover is hinged to the metal frame 4 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 pour tube 2 from a loading position 21 located far from the tap hole to a standby position 22 located just below the casting hole 27 on the plate mobile 10 when it is in position sealing the tap hole. The means of pushing 31 are pushed upwards by articulated levers 35 at 36 and subjected to the action of springs 37 at their end free 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 FIG. 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 travel according to arrow X of the two-plate drawer formed by the fixed upper plate 8 and the movable plate 10 when regulating the steel flow.

    Le châssis 4 doublement articulé facilite tout simplement l'accès aux pièces réfractaires, notamment à la plaque mobile 10.The double articulated chassis 4 simply facilitates access to 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.Assembly and disassembly of the articulated chassis 4 a device for supplying and exchanging a pouring tube 2 and regulating a ladle 3 on the bottom wall 5 of a ladle 3 is made as following.

    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'emboíter dans l'extrémité inférieure de la busette interne 23 une languette tronconique 37 d'une plaque supérieure 8.For mounting, an internal nozzle is positioned 23 in a seat brick 24 of the ladle 3 from below. There is a seal 25 on the flange lower protruding from the internal nozzle 23 and on coated the joint 25 with a refractory sealant before fitting in the lower end of the internal nozzle 23 a tapered 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 cartridges are retained in place spring loaded using a compression plate 16 removably attached to the top plate 8 using studs 17. To fix the compression plate 16 to the push cover 7, spring cartridges are compressed 13, 14 using a hydraulic tool not shown leaning on the compression plate 16 and the compression plate 16 is locked using anchor pieces comprising a wing nut 40. In releasing the hydraulic tools, the plate is released higher.

    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.We close the machine, by folding in the direction clockwork the push cover 7 on the metal frame 4 and by folding the metal frame 4 into the anti-clockwise direction against the bottom wall 5 of the ladle 3. This locking of the metal frame 4 is carried out by tilting the eye screws 26 in a notch 41 of the metal frame 4. The jack hydraulic is fixed to the mobile carriage by a stud introduced into the hole 28 formed in the lug 29 of 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.
