Description

DISPOSITIF D'AMENEE ET D'ECHANGE D'UN TUBE DE COULEE.DEVICE FOR FEEDING AND EXCHANGING A CASTING TUBE.
La présente invention est relative à un dispositif d'amenée et d'échange d'un tube de coulée pour récipient de coulée de métal par le bas, ayant une paroi de fond garnie d'une brigue de siège et d'une busette interne en matériau réfractaire, dispositif dans lequel un tube de coulée, ou une plaque de fin de coulée rapporté. e) à une bride supé¬ rieure, est monté(e) sur des guides aptes à transmet¬ tre un effort de poussée vers le haut et è guider leur déplacement depuis une position de chargement vers une position de service ou d'obturation dans l'axe du trou de coulée du récipient et de la position de service vers une position de dégagement , de manière è permet¬ tre l'échange du tube sans soulever le récipient.The present invention relates to a device for supplying and exchanging a pouring tube for a metal pouring container from below, having a bottom wall furnished with a seat race and an internal nozzle in refractory material, device in which a pouring tube, or an attached end-of-casting plate. e) to a upper flange, is mounted on guides capable of transmitting an upward thrust force and of guiding their movement from a loading position to a service or shutter position in the axis of the taphole of the container and the service position towards a release position, so that the tube can be exchanged without lifting the container.
Elle trouve sa principale application en sidérurgie dans les installations de coulée continue, par exemple dans un répartiteur de coulée continue obturé à l'aide d'une quenouille. Le fond d'un tel récipient comporte généralement une brique de siège dans laquelle est logée une busette interne délimitant un trou de coulée par lequel l'acier en fusion contenu dans le récipient s'écoule de façon continue dans une lingotière de coulée. Par le document EP-A-0192019, on connaît un dispositif d'amenée et d'échange d'un tube de coulée dans lequel une bride supérieure en matériau réfrac¬ taire d'un tube de coulée est amené à coulisser, sous l'action d'un double vérin pneumatique, le long d'une plaque de référence, de manière à glisser le long de celle-ci depuis une position de chargement jusqu'à une position de service dans l'alignement de l'axe du trou de coulée. Des rails-guides appliquent la bride supé- rieure du tube contre la plaque de référence sous l'effet d'une poussée vers le haut transmise par une première extrémité de leviers sur lesquels agissent vers le bas, à une extrémité opposée, des ressorts hélicoïdaux prenant appui sur le bâti du dispositif d'amenée et d'échange.It finds its main application in the steel industry in continuous casting installations, for example in a continuous casting distributor closed with a stopper. The bottom of such a container generally comprises a seat brick in which is housed an internal nozzle delimiting a tap hole through which the molten steel contained in the container flows continuously in a casting mold. Document EP-A-0192019 discloses a device for supplying and exchanging a pouring tube in which an upper flange made of material refractory to a pouring tube is caused to slide under the action of a double pneumatic cylinder, along a reference plate, so as to slide along it from a loading position to a service position in alignment with the axis of the casting. Guide rails apply the upper flange of the tube against the reference plate under the effect of an upward thrust transmitted by a first end of levers on which act downwards, at an opposite end, helical springs taking support on the frame of the supply and exchange device.
Les rails-guides sont parallèles entre eux et forment à l'entrée un plan légèrement incliné d'un angle pouvant être compris entre 2 et 10e par rapport au plan de référence.The guide rails are parallel to each other and form at the entrance a slightly inclined plane with an angle which can be between 2 and 10 e relative to the reference plane.
L'inclinaison des rails-guides par rapport au plan de référence de la plaque supérieure permet d'obtenir un serrage progressif de la plaque mobile rapportée au tube de coulée, lorsqu'on amène celui-ci dans l'alignement de l'orifice de coulée.The inclination of the guide rails relative to the reference plane of the upper plate makes it possible to obtain a progressive tightening of the movable plate attached to the pouring tube, when the latter is brought into alignment with the orifice of casting.
L'étanchéité entre la plaque de référence et la bride supérieure du tube de coulée en position de chargement est assurée à l'aide d'un culbuteur décrit dans la demande internationale PCT/BE90/00030. Ce culbuteur confère à la bride supérieure un mouvement de basculement autour d'une arête frontale horizontale de la bride supérieure lorsque celle-ci s'engage dans la zone d'étanchéité entourant le trou de coulée, de manière è rendre la bride supérieure strictement parallèle à la face inférieure de la plaque de référence.The seal between the reference plate and the upper flange of the pouring tube in the loading position is ensured using a rocker arm described in international application PCT / BE90 / 00030. This rocker arm gives the upper flange a tilting movement around a horizontal front edge of the upper flange when the latter engages in the sealing zone surrounding the tap hole, so as to make the upper flange strictly parallel to the lower face of the reference plate.
Dans les dispositifs décrits dans les docu¬ ments cités ci-avant, la plaque de référence et la busette interne constituent deux pièces distinctes jointives montées séparément dans le canal de coulée. La plaque de référence est verrouillée dans le bâti du dispositif d'amenée et d'échange d'un tube de coulée avant que celui-ci ne soit posé sous le conteneur métallurgique. Le verrouillage s'effectue sous la pression exercée sur la face inférieure de la plaque de référence par un système de leviers par l'intermé- diaire de la bride supérieure du tube, de manière è appliquer fermement sa face supérieure parfaitement plane sur la face inférieure de la plaque de référen¬ ce.In the devices described in the documents cited above, the reference plate and the internal nozzle constitute two separate contiguous parts mounted separately in the casting channel. The reference plate is locked in the frame of the device for supplying and exchanging a pouring tube before the latter is placed under the metallurgical container. The locking is effected under the pressure exerted on the underside of the reference plate by a system of levers by means of the upper flange of the tube, so as to firmly apply its perfectly flat upper face to the lower face. of the reference plate.
Le montage d'un dispositif d'amenée et d'échange d'un tube de coulée, contre le fond du conteneur, s'effectue en posant le dispositif contre le fond du conteneur et en le fixant à l'aide de boulons à oeillet engagés dans des pattes d'ancrage fixées au conteneur ou des boulons et douilles de centrage.The assembly of a device for supplying and exchanging a pouring tube, against the bottom of the container, is carried out by placing the device against the bottom of the container and fixing it with eyelet bolts. engaged in anchors attached to the container or centering bolts and sleeves.
Au moment du montage, le dispositif d'amenée et d'échange ne porte pas encore la busette interne mais le fond du conteneur est équipé d'une brique de siège.At the time of assembly, the supply and exchange device does not yet carry the internal nozzle but the bottom of the container is equipped with a seat brick.
Après avoir monté la machine sous le répartiteur, on pose la busette interne de l'intérieur du conteneur métallurgiσue, au travers de l'ouverture dans la brique de siège, sur la plaque de référence, au droit de la rainure annulaire laissée à nu par l'ouverture centrale dans la plaque supérieure du dispositif d'amenée et d'échange fixé sous le conte- neur.After mounting the machine under the distributor, the internal nozzle is placed from the inside of the metallurgical container, through the opening in the seat brick, on the reference plate, in line with the annular groove left exposed by the central opening in the upper plate of the supply and exchange device fixed under the container.
A cet effet, l'extrémité inférieure de la busette interne est munie d'une lèvre circonfèrentiel- le que l'on pose dans la rainure annulaire éventuelle- ment recouverte d'un liant non encore pris.For this purpose, the lower end of the internal nozzle is provided with a circumferential lip which is placed in the annular groove possibly covered with a binder not yet taken.
Lorsque le liant se durcit, il se forme entre la lèvre de la busette interne et la rainure de la plaque de référence un joint d'étanchêité qui empêche la pénétration d'air dans le canal de coulée et l'infiltration d'acier dans la rainure annulaire.When the binder hardens, a seal is formed between the lip of the internal nozzle and the groove of the reference plate which prevents the penetration of air into the runner and the infiltration of steel into the annular groove.
Etant donné que ce joint est soumis à des sollicitations thermiques considérables, il constitue le point faible de l'ensemble du système réfractaire.Since this joint is subjected to considerable thermal stresses, it constitutes the weak point of the entire refractory system.
La présente invention vise à remédier à cet inconvénient. Elle propose un dispositif d'amenée et d'échange d'un tube de coulée analogue à celui décrit dans le premier paragraphe du présent mémoire. Ce dispositif est caractérisé en ce σu'il comprend un siège formé de deux réglettes fixes strictement recti¬ lignes et parallèles entre elles, lequel siège est destiné à recevoir la face inférieure plane d'une plaque de référence et è recevoir de part et d'autre de celle-ci, des portions de plaques destinées à ser¬ vir de prolongements de la plaque de référence.The present invention aims to remedy this drawback. It proposes a device for supplying and exchanging a pouring tube similar to that described in the first paragraph of this memo. This device is characterized in that it comprises a seat formed by two fixed strips strictly recti¬ lines and parallel to each other, which seat is intended to receive the flat underside of a reference plate and to be received from both sides. other of this, portions of plates intended to serve as extensions of the reference plate.
Selon une particularité de l'invention, la plaque de référence a une longueur et une supérieures à cellesde la bride supérieure d'un tube de coulée.According to a feature of the invention, the reference plate has a length and a higher than those of the upper flange of a pouring tube.
Selon un développement de l'invention, la plaque de référence est une bride de la busette interne débordant du trou de coulée.According to a development of the invention, the reference plate is a flange of the internal nozzle projecting from the tap hole.
Dans une forme de réalisation particulière, le dispositif d'amenée et d'échange comporte un cadre en forme de U, constitué de deux pattes que l'on engage dans des étriers disposés dans un même plan vertical parallèle è la direction de déplacement du tube de coulée et que l'on verrouille en serrant la base du U reliant les deux pattes, contre le bâti du dispositif è l'aide de deux boulons è oeillet munis de cartouches à ressort engagés dans des échancrures de fixation.In a particular embodiment, the supply and exchange device comprises a U-shaped frame, consisting of two legs which are engaged in stirrups arranged in the same vertical plane parallel to the direction of movement of the tube and which is locked by tightening the base of the U connecting the two legs, against the frame of the device using two eyelet bolts fitted with spring cartridges engaged in fixing notches.
Le dispositif d'amenée et d'échange d'un tube de coulée suivant la présente invention se distingue du dispositif décrit dans le premier paragraphe du présent mémoire par le fait gue la busette interne solidaire de la plaque de référence est montée dans le dispositif avant sa fixation sur le fond du conteneur métallurgique. Le verrouillage de la plaque de référence s'effectue sous la pression exercée sur sa face supérieure par des épaulements du cadre que l'on rabat autour d'un axe parallèle è la direction de déplacement du tube de coulée, de manière à appliquer fermement la face inférieure parfaitement plane de la plaque de référence sur le siège constitué de deux réglettes parfaitement droites et parallèles.The device for supplying and exchanging a pouring tube according to the present invention differs from the device described in the first paragraph of this specification by the fact that the internal nozzle secured to the reference plate is mounted in the front device its attachment to the bottom of the metallurgical container. The locking of the reference plate is carried out under the pressure exerted on its upper face by shoulders of the frame which are folded around an axis parallel to the direction of movement of the pouring tube, so as to firmly apply the perfectly flat underside of the reference plate on the seat consisting of two perfectly straight and parallel strips.
Les pattes du cadre sont pourvues de raidisseurs. Elles transmettent une poussée vers le bas, au droit ' épaulements , sur la face supérieure de la bride de la busette interne gui déborde du trou de coulée.The legs of the frame are provided with stiffeners. They transmit a push downwards, to the right of the shoulders, on the upper face of the flange of the internal nozzle mistletoe protrudes from the tap hole.
La face inférieure parfaitement plane de la bride de la busette interne débordante repose sur le siège du dispositif d'amenée et d'échange, siège constitué de deux réglettes parfaitement rectilignes et parallèles. Sur ces deux réglettes sont fixées de part et d'autre du siège réservé à la plaque de référence . les portions de plaque destinées à servir de prolongements de la plaque de référence.The perfectly flat underside of the flange of the overflowing internal nozzle rests on the seat of the supply and exchange device, seat made up of two perfectly rectilinear and parallel strips. On these two strips are fixed on either side of the seat reserved for the reference plate. the plate portions intended to serve as extensions of the reference plate.
Le montage du dispositif contre le fond du conteneur métallurgique est semblable à celui décrit dans le premier paragraphe avec cette particularité qu'au moment du montage.le dispositif est équipé de la busette interne et le fond du conteneur ne comporte pas de brique de siège.The mounting of the device against the bottom of the metallurgical container is similar to that described in the first paragraph with the particularity that at the time of mounting. The device is equipped with the internal nozzle and the bottom of the container does not have a seat brick.

Dans ces figures, les mêmes signes de référen¬ ce désignent des éléments identiques et/ou analogues.In these figures, the same reference signs designate identical and / or analogous elements.
Comme illustré à la figure 1, un dispositif d'amenée et d'échange 1 d'un tube de coulée 2 comprend un châssis 3 sur lequel est montée une plaque de base 4 munie, en regard du trou de coulée 5, d'une fenêtre carrée 6 et d'un cadre 7 en forme de U. Le cadre 7 comprend deux pattes parallèles 8 que l'on introduit dans des étriers 9 fixés sur la plaσue 4, dans un même plan vertical parallèle è la direction de déplacement du tube de coulée 2 le long de rails-guides 10. Les pattes 8 sont renforcées par des raidisseurs 34.As illustrated in FIG. 1, a device for supplying and exchanging 1 of a pouring tube 2 comprises a frame 3 on which is mounted a base plate 4 provided, opposite the tap hole 5, with a square window 6 and a U-shaped frame 7. The frame 7 comprises two parallel legs 8 which are introduced into stirrups 9 fixed on the plate 4, in the same vertical plane parallel to the direction of movement of the tube casting 2 along guide rails 10. The legs 8 are reinforced by stiffeners 34.
Le cadre 7 est rabattable vers le haut et peut pivoter autour des étriers 9 formant charnières. Il est destiné à verrouiller une plaσue de référence, en particulier une bride 11 d'une busette interne 12, laquelle bride déborde du trou de coulée 5. La bride 11 ou plaque de référence est appliquée vers le bas contre un siège ménagé dans le dispositif d'amenée et d'échange 1 d'un tube de coulée 2. Ce siège est formé de deux réglettes 15 et 16 fixes, strictement rectili- gnes et parallèles entre elles. (Figure 4)The frame 7 is foldable upwards and can pivot around the stirrups 9 forming hinges. It is intended to lock a reference plate, in particular a flange 11 of an internal nozzle 12, which flange projects beyond the tap hole 5. The flange 11 or reference plate is applied downwards against a seat formed in the supply and exchange device 1 of a pouring tube 2. This seat is formed by two fixed strips 15 and 16, strictly rectilinear and parallel to each other. (Figure 4)
Sur les réglettes 15 et 16 sont fixées, de part et d'autre du siège réservé à la bride 11 de la busette interne 12, des portions de plaque de glisse- ment 17, 18 destinées à servir de prolongements de la plaque de référence.On the strips 15 and 16 are fixed, on either side of the seat reserved for the flange 11 of the internal nozzle 12, sliding plate portions 17, 18 intended to serve as extensions of the reference plate.
Un tube de coulée initial, ou un tube de coulée de remplacement, ou encore une plaque de fin de coulée, chacun d'eux étant rapporté à une bride supérieure 37, est monté coulissant sur des rails- guides 10 et des portions de rails portées par des leviers 35 aptes à transmettre auxdites portions de rails un effort de poussée vers le haut exercé sur les leviers par des ressorts 36 (Figure 2) . Les rails- guides déterminent la trajectoire des tubes de coulée 2, 2' mus sous l'action de vérins pneumatiques 29, 30 dans une direction perpendiculaire à l'axe (1,1') du trou de coulée 5, depuis une position de chargement vers une position de service ou d'obturation dans l'axe (1,1') du trou de coulée 5 et de la position de service vers une position de dégagement, de manière à permettre l'échange du tube 2 sans soulever le réci¬ pient ou conteneur 19. (Figure 3)An initial pouring tube, or a replacement pouring tube, or else an end of casting plate, each of which is attached to an upper flange 37, is slidably mounted on guide rails 10 and portions of rails carried by levers 35 capable of transmitting to said portions of rails an upward thrust force exerted on the levers by springs 36 (Figure 2). The guide rails determine the trajectory of the pouring tubes 2, 2 'moved under the action of pneumatic cylinders 29, 30 in a direction perpendicular to the axis (1,1') of the tap hole 5, from a position of loading towards a service or shutter position in the axis (1,1 ') of the tap hole 5 and from the service position towards a release position, so as to allow the exchange of the tube 2 without lifting the container or container 19. (Figure 3)
De manière connue, les brides supérieures 37 des tubes de coulée sont déplacées en translation le long de la plaque de référence par une paire de vérins pneumatiques 29 et 30 disposés parallèlement l'un à l'autre, afin de fournir la force nécessaire pour permettre un chargement rapide du tube de coulée 2 en utilisant au mieux le faible espace disponible en hauteur. Les tiges 27 et 28 des vérins 29 et 30 sont reliées entre elles par un châssis mobile 33 portant un bras-pousseur 25 escamotable.In known manner, the upper flanges 37 of the pouring tubes are moved in translation along the reference plate by a pair of pneumatic cylinders 29 and 30 arranged parallel to each other, in order to provide the force necessary for allow rapid loading of the pouring tube 2 by making the best use of the small space available in height. The rods 27 and 28 of the jacks 29 and 30 are interconnected by a movable frame 33 carrying a retractable pusher arm 25.
La busette interne 12 est montée sur le dispo¬ sitif d'amenée et d'échange avant que celui-ci ne soit monté de manière détachable sous un conteneur 19. En fait la bride 11 de la busette interne 12 est encas¬ trée dans la fenêtre 6 prévue dans la plaque de base 4 portée par le châssis 3 du dispositif d'amenée et d'échange et repose par sa face inférieure strictement plane sur les deux réglettes 15, 16 strictement recti- lignes et parallèles de manière è former un plan de référence.The internal nozzle 12 is mounted on the supply and exchange device before it is detachably mounted under a container 19. In fact the flange 11 of the internal nozzle 12 is embedded in the window 6 provided in the base plate 4 carried by the chassis 3 of the supply and exchange device and rests by its strictly planar lower face on the two strips 15, 16 strictly straight and parallel so as to form a plane reference.
Un cadre 7 rabattable permet de verrouiller la bride 11 de la busette interne 12 dans la fenêtre 6 de la tablette de base 4, par l'application d'une poussée vers le bas, au moyen d' épaulements 24 agissant sur la face supérieure de la bride 11 de la busette interne 12 de manière è appliquer celle-ci fermement contre le siège constitué des deux réglettes 15 et 16 parfaite- ment rectilignes et parallèles.A folding frame 7 makes it possible to lock the flange 11 of the internal nozzle 12 in the window 6 of the base shelf 4, by the application of a downward thrust, by means of shoulders 24 acting on the upper face of the flange 11 of the internal nozzle 12 so as to apply it firmly against the seat made up of two strips 15 and 16 perfectly rectilinear and parallel.
Ce dispositif d'amenée et d'échange est fixé de manière détachable sous le conteneur 19. Dans ce but, il est appliqué vers le haut sous le conteneur de manière à introduire la busette interne 12 dans une large ouverture de la paroi de fond du conteneur 19.This supply and exchange device is detachably fixed under the container 19. For this purpose, it is applied upwards under the container so as to introduce the internal nozzle 12 into a wide opening in the bottom wall of the container 19.
On fixe le dispositif d'amenée et d'échange sous le conteneur 19 è l'aide de boulons è oeillet 31 que l'on engage dans des pattes d'ancrage 22 fixées au conteneur 19 comme illustré dans la figure 5.The supply and exchange device is fixed under the container 19 using eyelet bolts 31 which are engaged in anchoring lugs 22 fixed to the container 19 as illustrated in figure 5.
Le fond du conteneur 19 comporte ainsi la busette interne 12 mais pas encore de brigue, de siège. On façonne une brique de siège 32 en disposant de chaque côté de la busette interne 12 un bloc réfrac- taire constituant une moitié de la brique de siège 32. Au lieu de mettre en place des demi-blocs, on peut également préparer un coffrage et damer du béton ré- fractaire autour de la busette interne 12. The bottom of the container 19 thus comprises the internal nozzle 12, but not yet a seat or a seat. A seat brick 32 is shaped by having a refractory block on each side of the internal nozzle 12 constituting one half of the seat brick 32. Instead of installing half-blocks, it is also possible to prepare formwork and grout refractory concrete around the internal nozzle 12.
