Description

La présente invention concerne un dispositif de mise en place d'un faux lingot en vue de la préparation d'une nouvelle coulée, dans une installation de coulée continue.The present invention relates to a device for placing a false ingot for the preparation of a new casting, in a continuous casting installation.

On connaît déjà un dispositif de ce genre comportant un panier dans lequel vient se loger le faux lingot que l'on sépare de la file de coulée, un système, de manutention pour amener le panier en position au-dessus de la lingotière, et des moyens pour introduire le faux lingot dans ladite lingotière.There is already known a device of this kind comprising a basket in which is housed the false ingot which is separated from the casting line, a handling system for bringing the basket into position above the ingot mold, and means for introducing the false ingot into said ingot mold.

Un tel dispositif est notamment décrit dans le brevet français n° 2 073 236 du 28 Novembre 1969.Such a device is described in particular in French patent No. 2,073,236 of November 28, 1969.

Suivant ce brevet, dès la fin d'une coulée, après que la lingotière ait été nettoyée et préparée en vue d'une nouvelle coulée, le panier contenant le faux lingot est amené au-dessus de la lingotière au moyen d'un pont roulant, puis il est posé verticalement sur le bord supérieur du châssis de la lingotière.According to this patent, at the end of a casting, after the mold has been cleaned and prepared for a new casting, the basket containing the false ingot is brought above the mold by means of a traveling crane , then it is placed vertically on the upper edge of the frame of the mold.

Cette disposition présente un certain nombre d'inconvénients. Aucun moyen de guidage du panier n'est prévu au cours de son transport par le pont roulant, ce qui est particulièrement désavantageux lorsque la masse du panier et du faux lingot est importante. Par ailleurs, le panier étant amené en position verticale au-dessus de la lingotière, les moyens d'introduction du faux lingot dans cette dernière doivent être aménagés à une hauteur importante au-dessus du plancher de coulée, ce qui conduit à un encombrement considérable.This arrangement has a number of drawbacks. No means of guiding the basket is provided during its transport by the traveling crane, which is particularly disadvantageous when the mass of the basket and the false ingot is large. Furthermore, the basket being brought into a vertical position above the ingot mold, the means for introducing the false ingot into the latter must be arranged at a significant height above the casting floor, which leads to considerable bulk. .

Un autre type de dispositif est également décrit dans la demande de brevet français n° 2 345 250.Another type of device is also described in French patent application No. 2,345,250.

Suivant cette demande, le faux lingot séparé de la file de coulée est saisi par le crochet d'un mécanisme de levage. Ce mécanisme est solidaire d'un wagonnet monté déplaçable sur un chariot de translation. Le chariot et le wagonnet sont immobiles au cours de l'opération de levage du faux lingot. Lorsque le crochet arrive à la hauteur du wagonnet, il pénètre dans des guidages dudit wagonnet. Le faux lingot est alors verticalement suspendu au crochet. Le déplacement du wagonnet le long du chariot, ce dernier restant immobile, permet de déposer le faux lingot en position allongée sur une glissière ou un transporteur aménagé sur le chariot. Ce dernier est alors déplacé en translation jusqu'à ce que son extrémité avant arrive à la verticale de la lingotière, tandis que lè wagonnet revient à sa position de départ à l'arrière du chariot. L'introduction du faux lingot dans la lingotière s'effectue sous l'action d'un organe entraîneur solidaire du wagonnet lorsque celui-ci se déplace à nouveau vers l'avant du chariot.Following this request, the false ingot separated from the casting queue is gripped by the hook of a lifting mechanism. This mechanism is integral with a wagon mounted movable on a translation carriage. The carriage and the wagon are stationary during the lifting operation of the false ingot. When the hook reaches the height of the wagon, it enters guides of said wagon. The false ingot is then vertically suspended from the hook. The movement of the wagon along the carriage, the latter remaining stationary, makes it possible to deposit the false ingot in the lying position on a slide or a conveyor arranged on the carriage. The latter is then moved in translation until its front end reaches the vertical of the mold, while the wagon returns to its starting position at the rear of the carriage. The introduction of the false ingot into the ingot mold takes place under the action of a driving member secured to the wagon when the latter again moves towards the front of the carriage.

Cette disposition présente un certain nombre d'inconvénients. On notera tout d'abord qu'il n'est prévu aucun panier. Il devient de ce fait nécessaire d'effectuer une opération de transfert du faux lingot entre les moyens de levage et le chariot de translation. Cela conduit à prévoir un wagonnet monté déplaçable sur le chariot de translation. Ce dernier doit être muni d'une glissière ou d'un transporteur présentant des extrémités courbées en arc de cercle afin de pouvoir introduire le faux lingot dans la lingotière sous l'action d'un organe entraîneur solidaire du wagonnet. La réalisation d'un tel dispositif devient de ce fait assez compliquée et peu économique.This arrangement has a number of drawbacks. It should first be noted that no basket is provided. It therefore becomes necessary to carry out a transfer operation of the false ingot between the lifting means and the translation carriage. This leads to providing a wagon mounted movable on the translation carriage. The latter must be fitted with a slide or a conveyor having ends curved in an arc so as to be able to introduce the false ingot into the ingot mold under the action of a driving member secured to the wagon. The realization of such a device therefore becomes quite complicated and uneconomical.

La présente invention a surtout pour but d'éviter les inconvénients des dispositifs connus.The main object of the present invention is to avoid the drawbacks of known devices.

Elle a plus précisément pour objet un dispositif de mise en place d'un faux lingot en vue de la préparation d'une nouvelle coulée dans une installation de coulée continue, comprenant un système de manutention pour amener le faux lingot, séparé de la file de coulée, en position au-dessus de la lingotière, des moyens étant prévus pour commander l'introduction du faux lingot par le haut dans la lingotière, ledit système de manutention étant constitué par un châssis de levage auquel sont attachés des moyens de levage et un châssis de translation dont les moyens de levage sont solidaires, ledit châssis de translation comprenant deux glissères verticales aptes à recevoir le châssis de levage, et des moyens commandant le déplacement du châssis de translation le long d'une voie horizontale, caractérisé en ce qu'il comporte, de façon connue en soi, un panier dans lequel vient se loger le faux lingot séparé de la file de coulée, en ce que le panier est monté sur le châssis de levage avec lequel il est amené en position au-dessus de la lingotière par le châssis de translation, et en ce que le panier porte les moyens pour commander l'introduction du faux lingot par le haut dans la lingotière.More specifically, it relates to a device for installing a false ingot for the preparation of a new casting in a continuous casting installation, comprising a handling system for bringing the false ingot, separated from the queue of casting, in position above the ingot mold, means being provided for controlling the introduction of the false ingot from above into the ingot mold, said handling system consisting of a lifting frame to which are attached lifting means and a translation chassis of which the lifting means are integral, said translation chassis comprising two vertical slides capable of receiving the lifting chassis, and means controlling the movement of the translation chassis along a horizontal track, characterized in that it comprises, in a manner known per se, a basket in which is housed the false ingot separated from the casting queue, in that the basket is mounted on the lifting frame with which it is brought into position above the mold by the translational frame, and in that the basket carries the means for controlling the introduction of the false ingot from above into the mold.

Le châssis de levage est monté déplaçable le long d'un chemin vertical.The lifting frame is mounted movable along a vertical path.

Ce chemin comprend, de chaque côté du panier, un montant de même section que les glissières du châssis de translation, de sorte que les dites glissières puissent être amenées en coïncidence avec lesdits montants.This path includes, on each side of the basket, an amount of the same section as the slides of the translation chassis, so that said slides can be brought into coincidence with said amounts.

Le châssis de levage comporte deux montants reliés à leur sommet par une traverse, lesdits montants, dont la hauteur est égale à celle des glissières du châssis de translation, étant équipés de galets roulant le long des montants formant chemin de roulement.The lifting frame comprises two uprights connected at their top by a cross member, said uprights, the height of which is equal to that of the slides of the translation frame, being fitted with rollers rolling along the uprights forming a raceway.

Le châssis de levage comporte, sur chacun de ses côtés, une manille d'accrochage des moyens de levage solidaires du châssis de translation.The lifting frame comprises, on each of its sides, a shackle for hooking the lifting means integral with the translation frame.

Les moyens de levage solidaires du châssis de translation sont constitués par deux treuils disposés de chaque côté dudit châssis, lesdits treuils étant entraînés par un même moteur.The lifting means integral with the travel chassis consist of two winches arranged on each side of said chassis, said winches being driven by the same motor.

Les moyens de commande du déplacement du châssis de translation le long de sa voie horizontale, sont constitués par des galets roulant sur ladite voie, deux galets situés de chaque côté de la voie étant des galets moteurs.The means for controlling the movement of the translational chassis along its horizontal track, consist of rollers rolling on said track, two rollers located on each side of the track being drive rollers.

Suivant une première forme de réalisation, le panier est monté pivotant sur le châssis de levage, et les deux glissières verticales du châssis de translation constituent un appui autorisant la rotation du panier.According to a first embodiment, the basket is pivotally mounted on the lifting frame, and the two vertical slides of the translation frame constitute a support allowing the basket to rotate.

Le panier comporte alors avantageusement, à son extrémité de sortie du faux lingot, un tourteau dont les dents viennent en prise avec les maillons de la chaîne que forme le faux lingot, le panier s'étendant sur un quart de cercle autour dudit tourteau.The basket then advantageously comprises, at its outlet end of the false ingot, an oil cake whose teeth come into engagement with the links of the chain that the false ingot forms, the basket extending over a quarter of a circle around said oil cake.

Le châssis de levage supporte alors un moteur apte à commander le renversement du panier à 180°.The lifting frame then supports a motor capable of controlling the tilting of the basket at 180 °.

Suivant une deuxième forme de réalisation, le panier est constitué par une gaine circulaire entourant un tourteau coaxial dont les dents viennent en prise avec les maillons de la chaîne que forme le faux lingot à travers la paroi intérieure de ladite gaine.According to a second embodiment, the basket is constituted by a circular sheath surrounding a coaxial cake, the teeth of which come into engagement with the links of the chain that the false ingot forms through the interior wall of said sheath.

La gaine s'étend sur un arc de cercle de 270° et présente des sections terminales rectilignes perpendiculaires entre elles, l'une étant horizontale, l'autre verticale.The sheath extends over a circular arc of 270 ° and has rectilinear end sections perpendicular to each other, one being horizontal, the other vertical.

Quelle que soit la forme de réalisation du panier, deux dents successives de la denture du tourteau sont séparées par un important intervalle, la position de ces dents par rapport à la première dent rencontrée par le faux lingot lors de son introduction dans le panier, et la dimension dudit intervalle, étant calculées de telle sorte que la tête du faux lingot puisse venir en prise avec le tourteau.Whatever the embodiment of the basket, two successive teeth of the teeth of the cake are separated by a large gap, the position of these teeth relative to the first tooth encountered by the false ingot when it is introduced into the basket, and the dimension of said interval, being calculated so that the head of the false ingot can come into engagement with the cake.

Le mouvement de rotation du tourteau est commandé par un moteur solidaire du panier, par l'intermédiaire d'un embrayage.The rotational movement of the cake is controlled by a motor secured to the basket, by means of a clutch.

Le panier est avantageusement monté sur le châssis de levage de manière à pouvoir coulisser latéralement.The basket is advantageously mounted on the lifting frame so that it can slide laterally.

L'invention sera mieux comprise en se référant à la description qui suit, faite en regard des dessins annexés, concernant deux formes particulières de réalisation données à titre d'exemples non limitatifs.The invention will be better understood by referring to the description which follows, given with reference to the appended drawings, relating to two particular embodiments given by way of nonlimiting examples.

La figure 1 est une vue d'ensemble d'une installation de coulée continue équipée du dispositif suivant l'invention; la figure 2 est une vue en coupe-élévation, suivant la ligne B-B de la figure 3, du panier contenant le faux lingot au moment de sa séparation de la file de coulée; la figure 3 est une vue en coupe suivant la ligne A-A de la figure 2; la figure 4 est une vue de face de l'ensemble du dispositif, le panier étant représenté en position renversée, son châssis de levage étant logé dans les glissières verticales de son châssis de translation; la figure 5 est une vue de dessus du dispositif tel que représenté sur la figure précédente; les figures 6, 7 et 8 sont des vues schématiques illustrant les principales étapes de la manutention du panier. Les figures 9, 10 et 11 sont des vues respectivement analogues à celles des figures 1, 2 et 3 illustrant une variante de réalisation.Figure 1 is an overview of a continuous casting installation equipped with the device according to the invention; Figure 2 is a sectional elevation view along line B-B of Figure 3, of the basket containing the false ingot at the time of its separation from the casting line; Figure 3 is a sectional view along line A-A of Figure 2; Figure 4 is a front view of the entire device, the basket being shown in the inverted position, its lifting frame being housed in the vertical slides of its translation frame; Figure 5 is a top view of the device as shown in the previous figure; Figures 6, 7 and 8 are schematic views illustrating the main steps of handling the basket. Figures 9, 10 and 11 are views respectively similar to those of Figures 1, 2 and 3 illustrating an alternative embodiment.

Sur la figure 1, on a représenté de façon schématique une installation de coulée continue courbe équipée du dispositif selon l'invention. Le repère 33 désigne une lingotière à la sortie de laquelle de produit coulé, brame par exemple, est guidé par un corset de guidage à rouleaux usuel comprenant une partie supérieure C et une partie inférieure C'. Le faux lingot 1 prévu pour le démarrage de la coulée, est ici représenté à l'intérieur d'un panier 2 qui repose sur la table à rouleaux T d'un transporteur d'évacuation du lingot, placé à la sortie du corset C-C'. C'est à partir de cette position que le faux lingot 1 est séparé, de façon connue en soi, de la file de coulée, et transporté dans son panier 2 comme cela sera expliqué par la suite. On a représenté en traits discontinus la position du panier 2 au moment de l'introduction du faux lingot 1 dans la lingotière 33. Les repères 12, 19, 22 et 23 désignent divers éléments du système de manutention du panier 2 qui seront décrits en référence aux figures 4 à 8 qui les montrent de façon plus détaillée.In Figure 1, there is shown schematically a continuous curved casting installation equipped with the device according to the invention. Reference 33 designates an ingot mold at the outlet of which poured product, for example a slab, is guided by a conventional roller guide corset comprising an upper part C and a lower part C '. The false ingot 1 provided for starting the casting, is here represented inside a basket 2 which rests on the roller table T of an ingot evacuation conveyor, placed at the outlet of the corset C- VS'. It is from this position that the false ingot 1 is separated, in a manner known per se, from the casting queue, and transported in its basket 2 as will be explained later. The position of the basket 2 has been shown in broken lines at the time of the introduction of the false ingot 1 into the ingot mold 33. The references 12, 19, 22 and 23 denote various elements of the basket 2 handling system which will be described with reference Figures 4 to 8 which show them in more detail.

Sur les figures 2 et 3, on voit le faux lingot 1 logé à l'intérieur de son panier 2 comme représenté sur la figure 1. Ce panier comporte, à son extrémité de sortie, un tourteau 3 dont les dents viennent en prise avec les maillons de la chaîne que forme le faux lingot 1. Ce dernier pénètre dans le panier 2 par l'extrémité d'entrée dudit panier opposée à celle qui est munie du tourteau 3. Lorsque la queue 4 du faux lingot 1 arrive au contact d'une dent du tourteau 3, celui-ci est entraîné en rotation au moyen du moteur 5 par l'intermédiaire du réducteur de vitesse 6. L'entraînement en rotation par le moteur 5 est arrêté dès que le premier maillon de la chaîne est en prise avec la dent du tourteau 3 qui suit la dent initialement rencontrée. La mise en route et l'arrêt du moteur 5 sont commandés automatiquement par un dispositif approprié. La progression du faux lingot 1 se poursuit alors d'elle-même jusqu'au moment où la queue 4 arrive dans la position verticale illustrée sur la figure 2. On remarquera que la denture du tourteau 3 présente entre deux dents successives un important intervalle 7. La position de ces dents par rapport à la première dent rencontrée et la dimension de leur intervalle sont calculées de telle sorte que la tête 8 du faux lingot 1 puisse venir en prise avec le tourteau 3 dans une étape ultérieure de fonctionnement dont il sera parlé plus explicitement par la suite. Dans la position représentée sur la figure 2, la tête 8 que l'on sépare de la file de coulée est située dans l'extrémité d'entrée du panier 2. C'est à partir de cette position que le panier 2 va être soulevé par des moyens de levage qui seront décrits plus loin. Sur la figure 3, le repère 9 désigne un embrayage monté sur l'arbre de sortie 10 du réducteur 6 et qui transmet le mouvement de rotation du moteur 5 au tourteau 3 par l'intermédiaire d'un arbre 11, concentrique à l'arbre 10, et sur lequel le tourteau 3 est monté. Un système de contacts électriques (non représentés) commande la rotation du tourteau 3, de telle sorte que ledit tourteau puisse être, à la demande, entraîne ou non par le moteur 5.In FIGS. 2 and 3, we see the false ingot 1 housed inside its basket 2 as shown in FIG. 1. This basket comprises, at its outlet end, a cake 3 whose teeth come into engagement with the links in the chain formed by the false ingot 1. The latter enters the basket 2 through the entry end of said basket opposite to that which is provided with the cake 3. When the tail 4 of the false ingot 1 comes into contact with a tooth of the cake 3, the latter is rotated by means of the motor 5 via the speed reducer 6. The rotation drive by the motor 5 is stopped as soon as the first link in the chain is engaged with the crab tooth 3 which follows the initially encountered tooth. The starting and stopping of the motor 5 is controlled automatically by an appropriate device. The progress of the false ingot 1 then continues by itself until the tail 4 arrives in the vertical position illustrated in FIG. 2. It will be noted that the toothing of the cake 3 has between two successive teeth a large interval 7 The position of these teeth relative to the first tooth encountered and the size of their interval are calculated so that the head 8 of the false ingot 1 can come into engagement with the cake 3 in a later stage of operation which will be discussed. more explicitly later. In the position shown in Figure 2, the head 8 which is separated from the casting line is located in the inlet end of the basket 2. It is from this position that the basket 2 will be lifted by lifting means which will be described later. In FIG. 3, the reference 9 designates a clutch mounted on the output shaft 10 of the reducer 6 and which transmits the rotational movement of the motor 5 to the cake 3 via a shaft 11, concentric with the shaft 10, and on which the cake 3 is mounted. An electrical contact system (not shown) controls the rotation of the cake 3, so that said cake may or may not be driven by the motor 5 on request.

Sur les figures 4 à 8, on a représenté un châssis de levage 12 du panier 2 sur lequel ledit panier est monté pivotant autour d'un arbre horizontal 13 reposant sur des paliers 14 solidaires du châssis de levage 12. Ce dernier est essentiellement formé par deux montants verticaux 15 à section en U, disposés de chaque côté du panier 2 et reliés, à leur partie supérieure, par une traverse 16. Chaque montant 15 du châssis de levage 12 est muni de galets 17 et 18 lui permettant de rouler le long d'un chemin de roulement vertical formé par un montant 19 à section en U. Les deux montants 19, disposés de chaque côté du châssis 12, sont fixés au sol à leur base. Par ailleurs, chaque montant 15 est muni d'une manille 20 à laquelle vient s'accrocher un câble de levage 21 sous l'action duquel le châssis 12 est soulevé, les galets 17 et 18 de ses montants 15 roulant alors comme précédemment indiqué.In Figures 4 to 8, there is shown a lifting frame 12 of the basket 2 on which said basket is pivotally mounted around a horizontal shaft 13 resting on bearings 14 integral with the lifting frame 12. The latter is essentially formed by two vertical uprights 15 of U-section, disposed on each side of the basket 2 and connected, at their upper part, by a cross member 16. Each upright 15 of the lifting frame 12 is provided with rollers 17 and 18 allowing it to roll along a vertical raceway formed by an upright 19 with a U-section. The two uprights 19, arranged on each side of the chassis 12, are fixed to the ground at their base. Furthermore, each upright 15 is provided with a shackle 20 to which a lifting cable 21 is hooked under the action of which the chassis 12 is raised, the rollers 17 and 18 of its uprights 15 then rolling as previously indicated.

Le repère 22 désigne globalement un châssis de translation apte à rouler le long d'une voie horizontale 23 à laquelle ledit châssis est suspendu. Le châssis 22 présente, sur chacun de ses côtés, une glissière verticale 24 ayant rigoureusement la même conformation que le montant 19 correspondant et qui se trouve initialement en coïncidence avec ledit montant, comme cela est particulièrement visible sur la figure 6. Le châssis 22 comporte en outre des moyens de levage constitués par deux treuils, tels que 25, disposés de chaque côté dudit châssis et tous deux entraînés par un même moteur 26, par l'intermédiaire d'un réducteur de vitesse 27. Chaque câble 21 vient s'enrouler autour d'un treuil 25, de telle sorte que le levage du châssis 12 est assuré. Lorsque ledit châssis poursuit sa course ascendante, ses montants 15 s'engagent dans les glissières 24. Quand le châssis 12 arrive en fin de course, les montants 15 ont quitté le chemin de roulement formé par les montants 19 et ils se trouvent entièrement logés dans les glissières 24 dont la longueur correspond exactement à celle des montants 15. Le repère 28 désigne l'intervalle de séparation, de faible longueur, prévu entre les montants 19 et les glissières 24.The reference 22 generally designates a translation chassis capable of rolling along a horizontal track 23 to which said chassis is suspended. The chassis 22 has, on each of its sides, a vertical slide 24 having strictly the same conformation as the corresponding upright 19 and which is initially coincident with said upright, as is particularly visible in FIG. 6. The chassis 22 comprises in addition lifting means constituted by two winches, such as 25, arranged on each side of said chassis and both driven by the same motor 26, by means of a speed reducer 27. Each cable 21 is wound up around a winch 25, so that the lifting of the chassis 12 is ensured. When said chassis continues its upward travel, its uprights 15 engage in the slides 24. When the chassis 12 reaches the end of its travel, the uprights 15 have left the raceway formed by the uprights 19 and they are entirely housed in the slides 24, the length of which corresponds exactly to that of the uprights 15. The reference 28 designates the separation interval, of short length, provided between the uprights 19 and the slides 24.

Lorsque le châssis 12 occupe la position que l'on vient de décrire, le châssis 22, ou plus précisément ses glissières 24, constituent pour lui un appui autorisant le renversement du panier 2 qui est resté maintenu en position horizontale. comme représenté sur la figure 2, tout au long de sa montée avec le châssis 12. Le mouvement de renversement à 180° du panier 2 s'effectue autour de l'arbre 13, et il est commandé par un moteur 29 solidaire du châssis 12. Le panier 2 renversé occupe la position illustrée par la figure 4, la queue 4 du faux lingot 1 étant dirigée vers le bas. Il est alors possible de déplacer le châssis 22 le long de sa voie horizontale 23 matérialisée par des poutres parallèles le long desquelles viennent rouler des galets tels que 30 et 31, prévus de chaque côté du châssis 22. Les galets 30 sont des galets d'entraînement commandés par des moteurs, tels que 32. Le déplacement en translation du châssis 22 entraînant avec lui le châssis 12, est arrêté dès que le panier 2 arrive au-dessus de la lingotière 33, la queue 4 du faux lingot 1 étant alors en position de mise en place dans ladite lingotière, comme cela est illustré par la figure 8. A ce moment le moteur 5 commande la rotation du tourteau 3 de telle sorte que le faux lingot 1 descende à l'intérieur de la lingotière 33 jusqu'à ce que sa queue 4 vienne en prise avec des rouleaux moteurs du corset C―C' qui entraînent le faux lingot 1 jusqu'à ce que sa tête 8 vienne obstruer la base de la lingotière 33. Le passage de la tête 8 autour du tourteau 3 est assuré grâce à l'intervalle 7 prévu entre deux dents du tourteau 3, comme cela a été indiqué précédemment. Le repère 34 désigne le plancher de coulée au-dessus duquel est aménagée la voie horizontale 23 du châssis 22. On remarquera que la différence de hauteur entre le plancher de coulée 34 et la voie 23 est relativement faible. Cela résulte du fait que, contrairement à la disposition décrite dans le brevet français n° 2 073 236, le panier 2 occupe une position horizontale, et non verticale, au-dessus de la lingotière 33.When the chassis 12 occupies the position that has just been described, the chassis 22, or more precisely its slides 24, constitute for it a support authorizing the overturning of the basket 2 which has remained maintained in a horizontal position. as shown in FIG. 2, throughout its rise with the chassis 12. The 180 ° inversion movement of the basket 2 takes place around the shaft 13, and it is controlled by a motor 29 integral with the chassis 12 The overturned basket 2 occupies the position illustrated in FIG. 4, the tail 4 of the false ingot 1 being directed downwards. It is then possible to move the chassis 22 along its horizontal path 23 materialized by parallel beams along which roll rollers such as 30 and 31, provided on each side of the chassis 22. The rollers 30 are rollers of drive controlled by motors, such as 32. The translational movement of the chassis 22 driving with it the chassis 12, is stopped as soon as the basket 2 arrives above the ingot mold 33, the tail 4 of the false ingot 1 then being in position of installation in said ingot mold, as illustrated by FIG. 8. At this moment the motor 5 controls the rotation of the cake 3 so that the false ingot 1 descends inside the ingot mold 33 up to that its tail 4 engages with motor rollers of the corset C ― C 'which drive the false ingot 1 until its head 8 comes to obstruct the base of the ingot mold 33. The passage of the head 8 around the cake 3 is ensured thanks to the interval 7 provided e between two teeth of cake 3, as indicated above. The reference 34 designates the pouring floor above which the horizontal track 23 of the chassis 22 is arranged. It will be noted that the difference in height between the casting floor 34 and the track 23 is relatively small. This results from the fact that, unlike the arrangement described in French Patent No. 2,073,236, the basket 2 occupies a horizontal position, not a vertical one, above the ingot mold 33.

Les figures 6, 7 et 8 auxquelles on s'est déjà référé dans ce qui précède illustrent les trois étapes principales de la manutention du panier 2. Dans le cas de la figure 6, le panier 2 est en position de départ, au moment de la séparation du faux lingot 1 de la file de coulée. Il est important que les montants 19 soient placés rigoureusement en coïncidence avec les glissières 24. Cela est obtenu en immobilisant le châssis 22 en position convenable le long de sa voie 23. Des butées, non représentées, pourraient avantageusement limiter la course du châssis 22 vers la droite, au delà de ladite position. Sur la figure 7, le panier 2 est représenté en cours de renversement autour de l'arbre 13 suivant la direction indiquée par la flèche. Les glissières 24 et les montants 19 sont encore en coîncidence. Contrairement à cette disposition, il serait possible d'effectuer le renversement du panier 2 après que le châssis 22 ait été déplacé en translation vers la gauche, par exemple à mi- parcours entre la position illustrée sur la figure 7 et celle illustrée sur la figure 8. Le renversement du panier 2 pourrait alors s'effectuer au-dessus d'une aire de stockage accessible à un opérateur chargé de dégager la tête 8 d'un tronçon de lingot coulé attaché à ladite tête, ou bien de remplacer le faux lingot par un autre faux lingot pris en magasin. Sur la figure 8 le panier 2 est représenté en position d'arrivée au-dessus de la lingotière 33. Des butées, non représentées, pourraient également être prévues pour empêcher le châssis 22 d'aller au delà de cette position en poursuivant sa course vers la gauche, le long de la voie 23.FIGS. 6, 7 and 8, to which reference has already been made in the foregoing, illustrate the three main stages in the handling of the basket 2. In the case of FIG. 6, the basket 2 is in the starting position, at the time of the separation of the false ingot 1 from the casting line. It is important that the uprights 19 are placed strictly in coincidence with the slides 24. This is obtained by immobilizing the chassis 22 in a suitable position along its track 23. Stops, not shown, could advantageously limit the stroke of the chassis 22 towards the right, beyond said position. In FIG. 7, the basket 2 is shown during overturning around the shaft 13 in the direction indicated by the arrow. The slides 24 and the uprights 19 are still in coincidence. Unlike this arrangement, it would be possible to overturn the basket 2 after the frame 22 has been moved in translation to the left, for example halfway between the position illustrated in FIG. 7 and that illustrated in FIG. 8. The overturning of the basket 2 could then take place above a storage area accessible to an operator responsible for clearing the head 8 from a section of cast ingot attached to said head, or else replacing the false ingot by another false ingot taken in store. In Figure 8 the basket 2 is shown in the arrival position above the mold 33. Stops, not shown, could also be provided to prevent the chassis 22 from going beyond this position by continuing its race to the left, along of track 23.

Lorsque le faux lingot 1 est en position de démarrage, sa tête 8 obstruant la base de la lingotière 33, il est possible de procéder à une nouvelle coulée. Au préalable, le panier 2 doit être ramené dans sa position de départ. La manutention du panier 2 vidé du faux lingot 1, s'effectue en procédant en sens inverse aux opérations que l'on vient de décrire. A cet effet, on déplace le châssis 22 jusqu'à ce que ses glissières 24 viennent en coïncidence avec les montants 19, on fait ensuite basculer le panier 2 de manière à le remettre dans sa position de réception du faux lingot, et l'on fait descendre le châssis 12 dont les montants 15 sortent des glissières 24 pour venir s'engager dans les montants 19 de leur chemin de roulement. L'opération de retour est terminée lorsque le châssis 12 retrouve sa position illustrée sur la figure 6. Une nouvelle coulée peut alors commencer.When the false ingot 1 is in the starting position, its head 8 obstructing the base of the ingot mold 33, it is possible to carry out a new casting. The basket 2 must first be returned to its starting position. The handling of the basket 2 emptied of the false ingot 1 is carried out by proceeding in the opposite direction to the operations which have just been described. For this purpose, the chassis 22 is moved until its slides 24 come into coincidence with the uprights 19, the basket 2 is then tilted so as to return it to its position for receiving the false ingot, and we lowers the chassis 12, the uprights 15 of which come out of the slides 24 to engage the uprights 19 of their raceway. The return operation is finished when the chassis 12 returns to its position illustrated in FIG. 6. A new casting can then begin.

Les figures 9 à 11 illustrent une variante de réalisation suivant laquelle le panier est conçu de telle sorte qu'il puisse être monté sur le châssis de levage, tout basculement dudit panier étant évité.Figures 9 to 11 illustrate an alternative embodiment according to which the basket is designed so that it can be mounted on the lifting frame, any tilting of said basket being avoided.

Sur ces figures, on a conservé les mêmes repères que sur les figures précédentes pour désigner les éléments identiques et l'on ne décrira ci-après que les éléments spécifiques de cette variante et ceux dont l'agencement est nettement modifié.In these figures, the same references have been kept as in the previous figures to designate identical elements and we will only describe below the specific elements of this variant and those whose arrangement is clearly modified.

Le repère 100 désigne globalement un panier délimité par deux parois latérales verticales, respectivement 101 et 103, et par une paroi enveloppe intermédiaire 104. Le contour de cette dernière présente la forme d'un arc de cercle s'étendant sur 270°, chaque extrémitè dudit arc de cercle étant prolongée par une ligne droite.The reference 100 generally designates a basket delimited by two vertical side walls, respectively 101 and 103, and by an intermediate envelope wall 104. The outline of the latter has the shape of an arc of circle extending over 270 °, each end of said circular arc being extended by a straight line.

Le panier 100 comprend une gaine 102 aménagée suivant le contour de la paroi 104. La paroi extérieure de la gaine 102 est constituée par la paroi 104. La paroi intérieure de la gaine 102 est formée par deux éléments des parois 105 et 106, respectivement solidaires des parois 101 et 103. Ces deux éléments de paroi, disposés en regard l'un de l'autre, sont agencés parallèlement à la paroi 104 sur toute l'étendue de son contour. La gaine 102 est limitée latéralement par les parois 101 et 103, plus précisément par les parties de ces parois comprises entre les éléments de paroi 105 et 106 et la paroi 104.The basket 100 comprises a sheath 102 arranged along the contour of the wall 104. The outer wall of the sheath 102 is constituted by the wall 104. The inner wall of the sheath 102 is formed by two elements of the walls 105 and 106, respectively integral walls 101 and 103. These two wall elements, arranged facing one another, are arranged parallel to the wall 104 over the entire extent of its contour. The sheath 102 is laterally limited by the walls 101 and 103, more precisely by the parts of these walls included between the wall elements 105 and 106 and the wall 104.

La gaine 102 ainsi définie s'étend sur un arc de cercle de 270° et présente des sections terminales rectilignes 107 et 108 perpendiculaires entre elles. La section 107, disposée horizontalement, constitue la section d'entrée du faux lingot 1, tandis que la section 108, disposée verticalement, constitue la section de sortie dudit faux lingot.The sheath 102 thus defined extends over a circular arc of 270 ° and has rectilinear end sections 107 and 108 perpendicular to each other. Section 107, arranged horizontally, constitutes the entry section of the false ingot 1, while section 108, arranged vertically, constitutes the exit section of said false ingot.

La gaine 102 entoure un tourteau 3 coaxial à ladite gaine. Les dents de ce tourteau viennent en prise avec les maillons de la chaîne que forme le faux lingot 1 logé dans la gaine 102, à travers la paroi intérieure de ladite gaine, plus précisément à travers le passage prévu entre les deux éléments de paroi 105 et 106.The sheath 102 surrounds a cake 3 coaxial with said sheath. The teeth of this cake come into engagement with the links of the chain formed by the false ingot 1 housed in the sheath 102, through the interior wall of said sheath, more precisely through the passage provided between the two wall elements 105 and 106.

Le panier 100 est monté sur le châssis de levage 12 de manière à ne pas pouvoir pivoter. Il peut toutefois être monté de manière à pouvoir coulisser latéralement en vue de positionner correctement la section d'entrée 107 par rapport au faux lingot 1. Cette dernière disposition est d'ailleurs valable pour le montage sur le châssis de levage 12 du panier 2 illustré sur les figures 1 à 8.The basket 100 is mounted on the lifting frame 12 so that it cannot pivot. However, it can be mounted so that it can slide laterally in order to correctly position the inlet section 107 relative to the false ingot 1. This latter arrangement is also valid for mounting on the lifting frame 12 of the basket 2 illustrated. in Figures 1 to 8.

Lorsqu'au moment de l'introduction du faux lingot 1 dans la gaine 102, la queue 4 dudit faux lingot arrive au contact de la première dent prédéterminée du tourteau 3, celui-ci est entraîné en rotation jusqu'à ce que le faux lingot 1 atteigne la position de stockage illustrée sur la figure 10. Au cours de cette rotation la queue 4 suit un parcours circulaire ascendant sur 180°, puis descendant sur 90°, et ensuite un parcours rectiligne descendant le long de la section de sortie 108.When at the time of the introduction of the false ingot 1 into the sheath 102, the tail 4 of said false ingot comes into contact with the first predetermined tooth of the cake 3, the latter is rotated until the false ingot 1 reaches the storage position illustrated in FIG. 10. During this rotation the tail 4 follows a circular path ascending over 180 °, then descending over 90 °, and then a straight path descending along the outlet section 108.

Le panier 100 peut alors être déplacé au moyen du système de manutention déjà décrit, de manière à amener la section 108 dans l'alignement de la cavité de la lingotière 33. La rotation du tourteau 3 commande alors la descente du faux lingot 1. On comprend facilement que la sortie du faux lingot 1 hors de la gaine 102 s'effectuant suivant une direction descendante, on évite le renversement prévu pour le panier 2 pour amener la queue 4 du faux lingot 1 au-dessus de la cavité de la lingotière 33.The basket 100 can then be moved by means of the handling system already described, so as to bring the section 108 into alignment with the cavity of the ingot mold 33. The rotation of the cake 3 then controls the descent of the false ingot 1. On easily understands that the exit of the false ingot 1 out of the sheath 102 taking place in a descending direction, the reversal provided for the basket 2 is avoided to bring the tail 4 of the false ingot 1 above the cavity of the ingot mold 33 .

Une rotation du tourteau 3 en sens inverse des précédentes peut également être commandée lorsque le panier 100 est arrêté au-dessus du plancher de coulée 34. On peut ainsi extraire la tête 8 du faux lingot 1 pour la remplacer ou éventuellement enlever un tronçon de lingot attaché à ladite tête.A rotation of the cake 3 in the opposite direction to the previous ones can also be controlled when the basket 100 is stopped above the casting floor 34. It is thus possible to extract the head 8 from the false ingot 1 to replace it or possibly remove a section of ingot attached to said head.

La structure du tourteau 3 ainsi que ses moyens de commande sont les mêmes que dans la forme de réalisation illustrée sur les figures 1 à 8.The structure of the cake 3 and its control means are the same as in the embodiment illustrated in FIGS. 1 to 8.

Bien que l'invention ait été décrite en référence à une forme particulière de réalisation, il va de soi qu'elle n'y est en rien limitée et que des modifications peuvent lui être apportées sans sortir de son domaine. On pourra notamment remplacer l'un quelconque des moyens décrits par un moyen techniquement équivalent. L'invention cbuvre en fait, non seulement l'exemple représenté, mais encore ses différentes variantes d'exécution possibles.Although the invention has been described with reference to a particular embodiment, it goes without saying that it is in no way limited thereto and that modifications can be made to it without departing from its field. We can in particular replace any of the means described by a technically equivalent means. The invention in fact works, not only the example shown, but also its various possible variants.
