Description

La présente invention concerne un dispositif pour projeter un revêtement réfractaire et/ou isolant thermique et/ou hydrofugeant sur les faces intérieures d'un récipient de transvasement de métal liquide, tel qu'un répartiteur de coulée, ce revêtement pouvant être permanent ou être un revêtement d'usure.The present invention relates to a device for spraying a refractory and / or thermal insulating and / or water repellent coating on the interior faces of a liquid metal transfer container, such as a pouring distributor, this coating being able to be permanent or to be a wear coating.

L'invention vise également le procédé pour la mise en oeuvre du dispositif selon l'invention.The invention also relates to the method for implementing the device according to the invention.

Un revêtement de ce type est décrit par exemple dans le brevet français 2 585 273 de la demanderesse.A coating of this type is described for example in French patent 2,585,273 of the applicant.

Dans les demandes de brevet français 87 04694 du 3 avril 1987 et 87 11466 du 12 août 1987, la demanderesse décrit en outre une machine pour préparer et projeter un revêtement similaire.In French patent applications 87 04694 of April 3, 1987 and 87 11466 of August 12, 1987, the applicant further describes a machine for preparing and spraying a similar coating.

On connaît un procédé de revêtement qui consiste à couler la composition de revêtement dans l'espace compris entre un gabarit et la surface intérieure du récipient à revêtir.A coating method is known which consists in casting the coating composition in the space between a template and the interior surface of the container to be coated.

L'utilisation d'un tel gabarit est peu pratique et ne permet pas de modifier à volonté l'épaisseur du revêtement.The use of such a template is impractical and does not allow the thickness of the coating to be changed at will.

Actuellement pour projeter un tel revêtement à l'intérieur d'un récipient de transvasement, on utilise un robot comportant des bras articulés dont les mouvements sont commandés à distance.Currently, to spray such a coating inside a transfer container, a robot is used comprising articulated arms, the movements of which are controlled remotely.

La construction d'un tel robot est lourde de complexe, de sorte qu'elle est très onéreuse.Building such a robot is complex, so it is very expensive.

On a proposé d'autre part un dispositif de projection comprenant une poutre fixée au-dessus d'un petit récipient de transvasement suivant l'axe longitudinal de celui-ci, sur laquelle est mobile en translation, un chariot portant la lance de projection du revêtement. Ce dispositif est économique, mais ne peut convenir que pour des récipients métallurgiques de petite dimension. De plus, il ne permet pas de projeter le revêtement suivant une distance constante entre la tête de la lance de projection et les faces intérieures du récipient, de sorte que la compacité du revêtement est irrégulière, ce qui est inacceptable.We have also proposed a projection device comprising a beam fixed above a small transfer container along the longitudinal axis thereof, on which is movable in translation, a carriage carrying the projection lance of the coating. This device is economical, but can only be suitable for small metallurgical vessels. In addition, it does not allow the coating to be projected at a constant distance between the head of the spray lance and the interior faces of the container, so that the compactness of the coating is irregular, which is unacceptable.

Ce dispositif ne convient pas notamment dans le cas de récipients de transvasement présentant des formes géométriques non parallélépipédiques et dont les parois latérales ne sont pas verticales mais inclinées.This device is not particularly suitable in the case of transfer containers having non-parallelepiped geometric shapes and whose side walls are not vertical but inclined.

Le but de la présente invention est de remédier aux inconvénients des réalisations connues en créant un dispositif de projection de construction simple et peu onéreuse et qui permette d'obtenir un revêtement de compacité régulière quelles que soient les dimensions et la forme des récipients de transvasementThe object of the present invention is to remedy the drawbacks of known embodiments by creating a projection device of simple construction and inexpensive and which makes it possible to obtain a coating of regular compactness whatever the dimensions and the shape of the transfer containers.

Le dispositif visé par l'invention pour projeter un revêtement sur les faces intérieures d'un récipient de transvasement de métal liquide comprend une lance de projection fixée verticalement à un chariot déplaçable dans un plan horizontal situé au-dessus du récipient de transvasement.The device contemplated by the invention for spraying a coating on the interior faces of a liquid metal transfer container comprises a spray lance fixed vertically to a trolley movable in a horizontal plane situated above the transfer container.

Suivant l'invention, ce dispositif est caractérisé en ce que le chariot est mobile en translation sur un guide s'étendant dans une première direction longitudinale ou transversale du récipient de transvasement, en ce que ce guide est lui-même mobile en translation sur des moyens de guidage s'étendant suivant une seconde direction transversale par rapport à la direction précitée, en ce que ces moyens de guidage sont eux-mêmes montés sur un support mobile en translation dans la direction longitudinale du récipient, et en ce que des moyens sont prévus pour commander les divers mouvements de la lance de projection de façon que la tête de projection de celle-ci soit maintenue à une distance sensiblement constante des faces latérales ou du fond du récipient de transvasement.According to the invention, this device is characterized in that the carriage is movable in translation on a guide extending in a first longitudinal or transverse direction of the transfer container, in that this guide is itself movable in translation on guide means extending in a second transverse direction relative to the aforementioned direction, in that these guide means are themselves mounted on a support movable in translation in the longitudinal direction of the container, and in that means are designed to control the various movements of the spray lance so that the spray head is kept at a substantially constant distance from the side faces or the bottom of the transfer container.

Etant donné que l'ensemble du dispositif de projection peut être déplacé dans la direction longitudinale du récipient de transvasement, ce dispositif peut avoir un encombrement en longueur inférieur à la longueur du récipient et il peut ainsi convenir à la fois pour les récipients de transvasement de petites et de grandes dimensions.Since the whole of the projection device can be moved in the longitudinal direction of the transfer container, this device can have a smaller overall dimensions than the length of the container and it can therefore be suitable for both transfer of small and large dimensions.

Etant donné que le chariot est mobile dans une direction transversale à la longueur du récipient, il est possible de régler la distance comprise entre la tête de la lance de projection et la paroi latérale du récipient, même lorsque celle-ci n'est pas verticale, mais inclinée ou n'est pas parallèle à la direction longitudinale du récipient de transvasement.Since the carriage is movable in a direction transverse to the length of the container, it is possible to adjust the distance between the head of the spray lance and the side wall of the container, even when the latter is not vertical , but inclined or not parallel to the longitudinal direction of the transfer container.

Selon une version avantageuse de l'invention, la lance de projection est mobile en rotation et en translation suivant un axe vertical.According to an advantageous version of the invention, the projection lance is movable in rotation and in translation along a vertical axis.

Ces déplacements de la lance de projection permettent en combinaison avec les autres mouvements du dispositif selon l'invention, de faciliter le maintien d'une distance constante entre la tête de la lance et la surface intérieure du récipient de transvasement quelle que soit la forme de celui-ci.These movements of the spray lance make it possible, in combination with the other movements of the device according to the invention, to facilitate the maintenance of a constant distance between the head of the lance and the interior surface of the transfer container whatever the form of this one.

Selon une version préférée de l'invention, le support du dispositif est mobile en translation sur des moyens de guidage s'étendant parallèlement à la direction longitudinale de plusieurs récipients de transvasement disposés en enfilade.According to a preferred version of the invention, the support of the device is movable in translation on guide means extending parallel to the longitudinal direction of several transfer containers arranged in a row.

Le même dispositif de construction simple, peu encombrante et peu onéreuse peut ainsi revêtir en série plusieurs répartiteurs de coulée disposés en enfilade.The same simple, space-saving and inexpensive construction device can thus be coated in series with several casting distributors arranged in a row.

Une fois les revêtement terminés, il suffit de dégager le dispositif dans une aire de stationnement située au-delà du dernier récipient de transvasement.Once the coating has been completed, it is sufficient to release the device in a parking area located beyond the last transfer container.

Selon un autre aspect de l'invention, le procédé pour la mise en oeuvre du dispositif de projection selon l'invention comprend les étapes suivantes :

  • a) on déplace le support du dispositif pour le mettre en position au-dessus du récipient,
  • b) on enduit le fond du récipient en projetant des bandes de revêtement parallèles en déplaçant le chariot dans la direction longitudinale du récipient et dans la direction perpendiculaire à cette dernière pour passer d'une bande à une autre, tout en maintenant la tête de la lance de projection à une distance constante du fond,
  • c) on enduit au moins une face latérale longitudinale et au moins une face latérale transversale du récipient en projetant des bandes de révêtement parallèles en déplaçant le chariot dans la direction longitudinale ou transversale du récipient, en faisant pivoter de 90° autour de son axe la tête de la lance, à l'extrémité d'une bande longitudinale pour projeter une bande sur la face transversale ou inversement, et, pour passer d'une bande à l'autre,on déplace la tête de la lance verticalement et le chariot transversalement ou longitudinalement pour maintenir une distance sensiblement constante entre la tête de la lance et la face latérale du récipient,
  • d) les étapes b) et c) pouvant être interverties.
According to another aspect of the invention, the method for implementing the projection device according to the invention comprises the following steps:
  • a) the support of the device is moved to position it above the container,
  • b) the bottom of the container is coated by projecting parallel covering strips by moving the carriage in the longitudinal direction of the container and in the direction perpendicular to the latter to pass from one strip to another, while keeping the head of the projection lance at a constant distance from the bottom,
  • c) at least one longitudinal side face and at least one transverse lateral face of the container are coated by projecting parallel covering strips by moving the carriage in the longitudinal or transverse direction of the container, by pivoting 90 ° around its axis. head of the lance, at the end of a longitudinal strip to project a strip on the transverse face or vice versa, and, to pass from one strip to another, the head of the lance is moved vertically and the carriage transversely or longitudinally to maintain a substantially constant distance between the head of the lance and the side face of the container,
  • d) steps b) and c) can be reversed.

Dans la réalisation des figures 1 et 2, on a représenté un dispositif 1 pour projeter un revêtement réfractaire et/ou isolant thermique et/ou hydrofugeant sur les faces intérieures d'un répartiteur de coulée 2. Ce revêtement peut être permanent ou être un revêtement d'usure.In the embodiment of FIGS. 1 and 2, a device 1 is shown for projecting a refractory and / or thermal insulating and / or water-repellent coating on the interior faces of a flow distributor 2. This coating can be permanent or be a coating of wear.

Ce dispositif de projection comprend une lance de projection 3 fixée verticalement à un chariot 4 déplaçable dans un plan horizontal situé au-dessus du répartiteur de coulée 2. La lance 3 est reliée à une tubulure souple 5 qui est elle-même reliée à une machine de préparation et de mise sous pression d'une composition de revêtement sous forme de boue, telle que décrite par exemple dans les demandes de brevet fran­çais n° 87 04694 du 3 avril 1987 et 87 11466 du 12 août 1987 au nom de la demanderesseThis projection device comprises a projection lance 3 fixed vertically to a carriage 4 movable in a horizontal plane situated above the casting distributor 2. The lance 3 is connected to a flexible tube 5 which is itself connected to a machine for preparing and pressurizing a coating composition in the form of mud, as described for example in French patent applications No. 87 04694 of April 3, 1987 and 87 11466 of August 12, 1987 in the name of the applicant

Conformément à l'invention, le chariot 4 est monté mobile en translation sur un guide 6 s'étendant dans la direction longitudinale D du répartiteur de coulée 2. Ce guide 6 est lui-même mobile en translation sur des moyens de guidage 7 s'étendant transversalement à la direction longitu­dinale D précitée.According to the invention, the carriage 4 is mounted movable in translation on a guide 6 extending in the longitudinal direction D of the tundish 2. This guide 6 is itself movable in translation on guide means 7 s' extending transversely to the above-mentioned longitudinal direction D.

Ces moyens de guidage 7 sont eux-mêmes montés sur un support 8 mobile en translation dans la direction longitudinale D du répartiteur de coulée 2.These guide means 7 are themselves mounted on a support 8 movable in translation in the longitudinal direction D of the tundish 2.

Des moyens 9, tels qu'un microordinateur associé à des moteurs sont prévus pour commander les divers mouvements de la lance de projection 3 portée par le chariot 4, de façon que la tête 3a de cette lance soit maintenue à une distance sensiblement constante des faces latérales 2a et 2b et du fond 3c du récipient de transvasement.Means 9, such as a microcomputer associated with motors are provided for controlling the various movements of the projection lance 3 carried by the carriage 4, so that the head 3a of this lance is kept at a substantially constant distance from the faces side 2a and 2b and the bottom 3c of the transfer container.

Dans la réalisation représentée, la lance de projection 3 est également mobile en translation et en rotation suivant un axe vertical (voir flèches F1 et F2 de la figure 2.In the embodiment shown, the projection lance 3 is also movable in translation and in rotation along a vertical axis (see arrows F1 and F2 of the figure 2.

Le guide 6 s'étendant dans la direction longitudinale D est une poutre sur laquelle le chariot 4 est monté mobile au moyen de roulettes 4a.The guide 6 extending in the longitudinal direction D is a beam on which the carriage 4 is mounted movable by means of rollers 4a.

Les extrémités opposées de la poutre 6 comportent deux chariots 6a, 6b équipés de roulettes, montés de façon mobile sur deux traverses 8 s'étendant perpendiculairement à la direction longitudinale D du répartiteur de coulée 2.The opposite ends of the beam 6 comprise two carriages 6a, 6b fitted with rollers, mounted movably on two crosspieces 8 extending perpendicular to the longitudinal direction D of the tundish distributor 2.

Les extrémités opposés des traverses 8 comportent des roulettes 10 qui sont montées sur deux rails de guidage 11 qui s'étendent respectivement de part et d'autre des faces latérales longitudinales 2a du répartiteur de coulée 2.The opposite ends of the crosspieces 8 comprise rollers 10 which are mounted on two guide rails 11 which extend respectively on either side of the longitudinal lateral faces 2a of the tundish distributor 2.

Les deux traverses 8 sont reliées entre elles par des longerons 12 fixés aux extrémités de ces traverses 8 de façon à créer un châssis rigide.The two cross members 8 are interconnected by side members 12 fixed to the ends of these cross members 8 so as to create a rigid frame.

Dans la réalisation représentée, la longueur de ce châssis est sensiblement égale à la moitié de la longueur du répartiteur de coulée 2, tandis que sa largeur est légèrement supérieure à la largeur de ce répartiteur.In the embodiment shown, the length of this chassis is substantially equal to half the length of the casting distributor 2, while its width is slightly greater than the width of this distributor.

Ainsi, en déplaçant le chariot 4 sur la poutre 6 et en déplaçant les chariots 6a de la poutre sur les guides transversaux 7, on peut revêtir l'intérieur du répartiteur de coulée sur la moitié de sa longueur et sur la totalité de sa largeur.Thus, by moving the carriage 4 on the beam 6 and by moving the carriages 6a of the beam on the transverse guides 7, it is possible to coat the interior of the casting distributor over half of its length and over its entire width.

Dans la réalisation de la figure 3, le dispositif 1 est monté sur des rails 11 s'étendant parallèlement à la direction longitudinale D de plusieurs répartiteurs de coulée 2, 2A, 2B, 2C disposés en enfilade.In the embodiment of Figure 3, the device 1 is mounted on rails 11 extending parallel to the longitudinal direction D of several casting distributors 2, 2A, 2B, 2C arranged in a row.

Ces rails de guidage 11 s'étendent au-delà de l'extrémité du répartiteur de coulée 2C situé en bout de file, de façon à constituer une aire de stationnement 11a du dispositif 1, dégagée de l'ouverture supérieure des répartiteurs de coulée.These guide rails 11 extend beyond the end of the tundish 2C located at the end of the line, so as to constitute a parking area 11a of the device 1, released from the upper opening of the tundish.

Les déplacements de l'ensemble du dispositif 1 sur les rails 11, des chariot 6a, 6b de la poutre 6, du chariot 4 sur la poutre 6, la translation et la rotation de la lance 3 portée par le chariot 4 sont commandés automatiquement à l'aide du microordinateur 9 selon un cycle de fonctionnement prédéterminé qui assure que la tête 3a de la lance 3 reste à une distance constante de la surface intérieure des répartiteurs de coulée 2, 2A, 2B, 2C.The movements of the entire device 1 on the rails 11, of the carriage 6a, 6b of the beam 6, of the carriage 4 on the beam 6, the translation and the rotation of the lance 3 carried by the carriage 4 are automatically controlled using the microcomputer 9 according to a predetermined operating cycle which ensures that the head 3a of the lance 3 remains at a constant distance from the internal surface of the tundish distributors 2, 2A, 2B, 2C.

Les fins de course de déplacement du dispositif sur les rails 11 peuvent être déterminés par des contacteurs électriques 13 (voir figure 1), arrêtant le fonctionnement du moteur d'entraînement du dispositif lorsque celui-ci atteint une position dans laquelle il est apte à revêtir la moitié de la surface intérieure d'un répartiteur de coulée.The end positions of movement of the device on the rails 11 can be determined by electrical contactors 13 (see FIG. 1), stopping the operation of the drive motor of the device when the latter reaches a position in which it is capable of coating half the interior surface of a tundish.

Ainsi, pour chaque répartiteur de coulée, le dispositif 1 occupera deux positions successives, à savoir celle représentée en trait plein sur les figures 1 et 2 et celle représentée en traits pointillés sur la figure 1.Thus, for each casting distributor, the device 1 will occupy two successive positions, namely that represented in solid lines in FIGS. 1 and 2 and that represented in dotted lines in FIG. 1.

Dans la réalisation des figures 6 et 7, le chariot 4 est monté mobile en translation sur un guide 106 s'étendant dans la direction transversale L du répartiteur de coulée 2. Ce guide 106 est lui-même mobile en translation sur des moyens de guidage 107 s'étendant selon la direction longitudinale D précitée.In the embodiment of FIGS. 6 and 7, the carriage 4 is mounted movable in translation on a guide 106 extending in the transverse direction L of the tundish distributor 2. This guide 106 is itself movable in translation on guide means 107 extending in the above-mentioned longitudinal direction D.

Les moyens de guidage 107 sont eux-mêmes montés sur les longerons 12 qui constituent avec les traverses 8, comme dans le premier mode de réalisation décrit ci-dessus en référence aux figures 1 et 2, un support mobile en translation dans la direction longitidinale D du répartiteur de coulée 2.The guide means 107 are themselves mounted on the side members 12 which constitute, with the crosspieces 8, as in the first embodiment described above with reference to FIGS. 1 and 2, a support movable in translation in the longitudinal direction D of the tundish 2.

Les autres caractéristiques de ce second mode de réalisation sont identiques à celles du premier mode de réalisation.The other characteristics of this second embodiment are identical to those of the first embodiment.

On va maintenant décrire à titre d'exemple non limitatif la mise en oeuvre du dispositif de projection conforme au premier mode de réalisation de l'invention, en référence aux figures 1 à 5.We will now describe, by way of nonlimiting example, the implementation of the projection device according to the first embodiment of the invention, with reference to FIGS. 1 to 5.

Dans un premier temps, on déplace le dispositif 1 sur les rails 11 pour le mettre en position au-dessus du répartiteur de coulée 2, comme indiqué sur la figure 1. Dans cette position, la tête 3a de la lance 3 peut balayer toute la surface intérieure du répartiteur sur la moitié de sa longueur.Firstly, the device 1 is moved on the rails 11 to place it in position above the casting distributor 2, as shown in FIG. 1. In this position, the head 3a of the lance 3 can sweep the entire interior surface of the distributor over half its length.

On commence par enduire le fond 2c du répartiteur en déplaçant le chariot 4 dans une direction F₃ (voir figure 4) parallèle à la direction D pour projeter une bande de revêtement b₁ s'étendant entre le milieu M du répartiteur et la face latérale transversale 2b.We start by coating the bottom 2c of the distributor by moving the carriage 4 in a direction F₃ (see Figure 4) parallel to direction D to project a strip of coating b₁ extending between the middle M of the distributor and the transverse lateral face 2b .

Puis on projette une autre bande b₂ jointive à la précédente après avoir déplacé les chariots 6a et 6b perpendiculairement à la direction longitudinale D. On procède de cette façon jusqu'à recouvrir toute la demi-­largeur du fond 2c du répartiteur. Pendant cette projection, la tête 3a de la lance reste à une distance constante du fond 2c.Then we project another strip b₂ contiguous to the previous one after having moved the carriages 6a and 6b perpendicular to the longitudinal direction D. We proceed in this way until covering the entire half-width of the bottom 2c of the distributor. During this projection, the head 3a of the lance remains at a constant distance from the bottom 2c.

Ensuite, on enduit une face latérale longitudinale 2a et une face latérale transversale 2b en projetant des bandes successives parallèles et jointives telles que b₃ (voir figure 5). A cet effet, on amène la tête 3a de la lance à la distance d désirée de la paroi 2a, on déplace le chariot 4 dans la direction F₄ parallèle à la longueur D. Lorsque la tête 3a est distante de d de la face transversale 2b, on tourne la tête 3a de 90° et on déplace les chariots 6a, 6b dans une direction perpendiculaire à D.Next, a longitudinal lateral face 2a and a transverse lateral face 2b are coated by projecting successive parallel and contiguous strips such as b₃ (see FIG. 5). To this end, the head 3a of the lance is brought to the desired distance d from the wall 2a, the carriage 4 is moved in the direction F₄ parallel to the length D. When the head 3a is distant from d from the transverse face 2b , the head 3a is turned by 90 ° and the carriages 6a, 6b are moved in a direction perpendicular to D.

La bande suivante est projetée de la même façon. Etant donnée que les parois latérales 2a et 2b sont inclinées, on maintient la distance d entre la tête 3a et la surface intérieure du répartiteur au moyen des chariots 6a, 6b (pour la paroi 2a) et du chariot 4 (pour la paroi 2b).The next tape is projected in the same way. Since the side walls 2a and 2b are inclined, the distance d between the head 3a and the interior surface of the distributor is maintained by means of the carriages 6a, 6b (for the wall 2a) and the carriage 4 (for the wall 2b) .

On procède de la même façon pour l'autre demi-­largeur et l'autre demi-longueur du répartiteur de coulée.The same procedure is followed for the other half-width and the other half-length of the tundish.

La mise en oeuvre du dispositif de projection conforme au second mode de réalisation de l'invention est tout à fait comparable à ce que l'on vient de décrire, le chariot 4 se déplaçant sur la poutre 106 selon la direction L transversale par rapport au répartiteur de coulée 2, la poutre 106 se déplaçant elle-même sur les guides longitudinaux 107.The implementation of the projection device according to the second embodiment of the invention is entirely comparable to what has just been described, the carriage 4 moving on the beam 106 in the direction L transverse to the flow distributor 2, the beam 106 moving itself on the longitudinal guides 107.

On comprendra qu'il est également possible d'intervertir les étapes décrites ci-dessus et d'enduire d'abord les faces latérales transversales et longitudinales (dans un ordre et un sens quelconque), puis le fond du répartiteur.It will be understood that it is also possible to reverse the steps described above and to first coat the transverse and longitudinal side faces (in any order and in any direction), then the bottom of the distributor.

Les principaux avantages du dispositif de projection que l'on vient de décrire sont les suivants :The main advantages of the projection device just described are as follows:

Il est de construction simple, légère et peu encombrante, et ne gêne pas l'accès aux différents répartiteurs de coulée.It is simple, light and space-saving, and does not hinder access to the various casting distributors.

Ses différents organes sont déplacés selon des mouvements de translation et de rotation simples qui peuvent être facilement programmés.Its various organs are moved in simple translational and rotational movements which can be easily programmed.

Ces divers mouvements permettent de maintenir la tête 3a de la lance à une distance constante de la surface intérieure du répartiteur de coulée en tout point de celui-ci, ce qui permet d'obtenir un revêtement dont la compacité est régulière.These various movements make it possible to maintain the head 3a of the lance at a constant distance from the internal surface of the tundish at any point thereof, which makes it possible to obtain a coating whose compactness is regular.

De plus, le dispositif malgré ses faibles dimensions est apte à revêtir l'intérieur de plusieurs répartiteurs de coulée en enfilade.In addition, the device, despite its small dimensions, is able to coat the interior of several flow distributors in a row.

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation que l'on vient de décrire et on peut apporter à ceux-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and many modifications can be made to them without departing from the scope of the invention.

Ainsi, la structure du dispositif peut être modifiée pourvu que les différents mouvements fondamentaux du chariot 4 soient conservés.Thus, the structure of the device can be modified provided that the various fundamental movements of the carriage 4 are preserved.

De même, le microordinateur 9 peut être remplacé par des commandes à distance actionnées manuellement par un opérateur, ou installé en parallèle avec de telles commandes. La longueur des longerons 12 peut être différente de celle indiquée ci-dessus, et on peut faire en sorte que le lance 3 puisse tourner sur elle-même de plusieurs quarts de tour successifs.Likewise, the microcomputer 9 can be replaced by remote controls operated manually by an operator, or installed in parallel with such controls. The length of the side members 12 may be different from that indicated above, and it can be made so that the lance 3 can turn on itself by several quarter turns successive.

De plus, au microordinateur programmé ou aux commandes à distance actionnées manuellement pour commander les mouvements du chariot 4 et de la lance 3 peuvent être associés des moyens de détection permettant de maintenir une distance constante entre la surface à revêtir et la tête 3a de la lance de projection tels que, par exemple :
- des tiges télescopiques sensibles détectant une distance constante et agissant sur des interrupteurs qui peuvent asservir les différents moteurs assurant la motricité du dispositif,
- des sondes à ultra-sons,
- des sondes à rayons infra-rouges.In addition, the programmed microcomputer or the manually operated remote controls for controlling the movements of the carriage 4 and the lance 3 can be associated with detection means making it possible to maintain a constant distance between the surface to be coated and the head 3a of the lance. projection such as, for example:
- sensitive telescopic rods detecting a constant distance and acting on switches which can control the various motors ensuring the drive of the device,
- ultrasonic probes,
- infrared ray probes.

D'autre part, la mise en oeuvre du dispositif et celle du revêtement peuvent être différentes de celles décrites. Ainsi, si la largeur du répartiteur de coulée 2 et les conditions de projection de ce revêtement s'y prêtent, il peut être possible, en particulier avec le dispositif suivant le premier mode de réalisation, le dispositif étant placé à une extrémité du répartiteur, d'enduire, sans déplacer le chariot 4 ni la poutre 6, la face transversale 2b et le début des deux faces longitudinales 2a en faisant simplement pivoter la lance de projection 3, et éventuellement en réglant son niveau en hauteur, et de terminer le revêtement en déplaçant longitudinalement le chariot 4 le long de la poutre 6 et celle-ci le long des rails 11.On the other hand, the implementation of the device and that of the coating may be different from those described. Thus, if the width of the flow distributor 2 and the conditions for projecting this coating lend themselves to it, it may be possible, in particular with the device according to the first embodiment, the device being placed at one end of the distributor, coat, without moving the carriage 4 or the beam 6, the transverse face 2b and the beginning of the two longitudinal faces 2a by simply rotating the spray lance 3, and possibly by adjusting its level in height, and finishing the coating by moving the carriage 4 longitudinally along the beam 6 and the latter along the rails 11.
