Description

La présente invention concerne une méthode d'adaptation d'une installation de revêtement d'un produit à défilement selon le préambule de la revendication 1.The present invention relates to a method of adapting an installation for coating a scrolling product according to the preamble of claim 1.

Usuellement, une installation de revêtement d'un produit à défilement sous une direction dite longitudinale comprend un pot de revêtement, comprenant un agent de revêtement tel qu'un un métal liquide (zinc ou alliages divers), dans lequel vient plonger le produit afin de ressortir dudit pot revêtu dudit agent. Un tel pot de revêtement est généralement disposé dans une enceinte au moins partiellement voire complètement enterrée par rapport au niveau du sol. Lors d'un remplacement de pot pour des raisons diverses, l'installation de revêtement est mise en arrêt de production. Le pot est vidé, démonté puis évacué de l'enceinte et enfin il est remplacé par un autre pot prêt à l'usage, à remplir d'agent de revêtement. De tels arrêts de production d'au moins un à plusieurs jours sont fort coûteux pour le propriétaire de l'installation. Enfin, pour le cas d'un revêtement maintenu à une température précise, le déplacement de pots est toujours critique en ce que sa structure réfractaire est facilement vouée à être déformée et le plus souvent fissurée. La maintenance de tels pots est ainsi extrêmement difficile voire impossible. En particulier, des déplacements par élévation de pot ou descente du pot engendrent de telles fissures ou déformations non réversibles des pots. Il est alors requis de prévoir des moyens d'élévation ou de descente très complexe et donc coûteux, sans toutefois garantir un résultat sans risque. De plus, si un pot doit être déplacé de manière bidirectionnelle au sol, il est nécessaire de prévoir des moyens de transport ou transfert rigides et conséquents, de façon à également éviter tout risque de déformation et fissuration lors d'un changement de direction de transport ou transfert.Usually, an installation for coating a product moving in a so-called longitudinal direction comprises a coating pot, comprising a coating agent such as a liquid metal (zinc or various alloys), in which the product is immersed in order to emerge from said pot coated with said agent. Such a coating pot is generally arranged in an enclosure at least partially or even completely buried with respect to ground level. When a pot is replaced for various reasons, the coating installation is shut down. The pot is emptied, dismantled then evacuated from the enclosure and finally it is replaced by another ready-to-use pot, to be filled with coating agent. Such production stoppages of at least one to several days are very costly for the owner of the installation. Finally, in the case of a coating maintained at a precise temperature, the displacement of pots is always critical in that its refractory structure is easily doomed to be deformed and most often cracked. The maintenance of such pots is thus extremely difficult or even impossible. In particular, displacements by raising the pot or lowering the pot generate such cracks or non-reversible deformations of the pots. It is then necessary to provide very complex and therefore costly means of elevation or descent, without however guaranteeing a result without risk. In addition, if a pot must be moved bidirectionally on the ground, it is necessary to provide rigid and substantial means of transport or transfer, so as to also avoid any risk of deformation and cracking during a change of direction of transport. or transfer.

A titre d'exemples, JP2003231958 ou GOTOH et al : « The outline of No.2 continuous galvanizing line at Kashima works", revue de métallurgie - cahiers d'informations techniques, vol 91, no 4, avril 1994, (1994-4), pages 575-580, XP000449410, ISSN : 0035-1563, DOI :10.13140/2.1.16142085 présentent de telles installations de galvanisation comprenant des pots permutables à des fins de maintenance.As examples, JP2003231958 Where GOTOH et al: “The outline of No.2 continuous galvanizing line at Kashima works”, metal review - technical information books, vol 91, no 4, April 1994, (1994-4), pages 575-580, XP000449410 , ISSN: 0035-1563, DOI: 10.13140/2.1.16142085 present such galvanizing installations comprising switchable pots for maintenance purposes.

Un but de la présente invention est de proposer une méthode pour adapter une installation comprenant un premier pot de revêtement d'un produit à défilement longitudinal, ledit premier pot étant disposé dans une première enceinte, et dont l'adaptation effectuée garantit un arrêt de durée minimale voire nul de la production. Egalement, cette adaptation devrait permettre une maintenance sécurisée de pot au regard de facteurs de déformations ou fissures. Enfin, la dite maintenance de pot devrait s'effectuer sous une durée minimale afin de ne pas diminuer la productivité de l'installation.An object of the present invention is to propose a method for adapting an installation comprising a first pot for coating a longitudinally moving product, said first pot being placed in a first enclosure, and the adaptation of which guarantees a stoppage of duration minimal or even zero production. Also, this adaptation should allow safe maintenance of the pot with regard to deformation or crack factors. Finally, said pot maintenance should be carried out within a minimum period so as not to reduce the productivity of the installation.

Il est ainsi proposé une telle méthode d'adaptation d'une installation comprenant un premier pot de revêtement d'un produit à défilement longitudinal au travers des caractéristiques de la revendication 1. Une installation réalisée selon ladite méthode d'adaptation est aussi présentée au travers des caractéristiques de la revendication 10.There is thus proposed such a method of adapting an installation comprising a first pot for coating a product with longitudinal scrolling through the characteristics of claim 1. An installation produced according to said adaptation method is also presented through of the features of claim 10.

Figures 1A, 2A, 3A (figures de type A) présentent des vues de dessus lors d'étapes de réalisation d'une première installation comprenant un premier pot (p1) à remplacer ou à compléter par un deuxième pot (p2) selon la méthode prévue pour l'invention. Figures 1A, 2A, 3A (Figures of type A) show top views during stages of production of a first installation comprising a first pot (p1) to be replaced or supplemented by a second pot (p2) according to the method provided for the invention.

Figures 1B, 2B, 3B (figures de type B sous forme de coupe A-A des figures de type A) présentent des vues de côté lors d'étapes de réalisation d'une première installation selon figures 1A, 2A, 3A. Figures 1B, 2B, 3B (type B figures in the form of section AA of the type A figures) present side views during stages of production of a first installation according to Figures 1A, 2A, 3A .

Selon les figures 1A et 1B, il est présenté une configuration initialement mono-pot d'installation de revêtement d'un produit en défilement (pr_ON) selon un plan longitudinal (X, Z) tel d'un produit plat et long (bande ou séquence de bandes). Ce produit est plongé de manière inclinée en partie haute dans le premier pot (p1) contenant un métal liquide tel que du zinc ou des alliages divers. Après avoir été dévié par un rouleau de fond (rf) disposé dans le pot, le produit défile ainsi dans le pot et ressort verticalement du pot. Généralement, le pot est placé dans une enceinte (e1) qui entoure latéralement le pot au moins partiellement ou sinon son périmètre, de manière par exemple semi-enterrée ou complétement enterrée (fosse). Plus généralement, ce type d'enceinte est donc prévu dans un espace aérien ou/et au moins partiellement sous forme de fosses. Des pieds (pf) ou un autre support de fonds peuvent alors être prévus pour le maintenir stablement dans le fond de l'enceinte.According to figures 1A and 1B , there is presented an initially single-pot configuration for the coating installation of a scrolling product (pr_ON) along a longitudinal plane (X, Z) such as a flat and long product (strip or sequence of strips). This product is immersed in an inclined manner in the upper part in the first pot (p1) containing a liquid metal such as zinc or various alloys. After having been deflected by a bottom roller (rf) arranged in the pot, the product thus scrolls through the pot and emerges vertically from the pot. Generally, the pot is placed in an enclosure (e1) which laterally surrounds the pot at least partially or otherwise its perimeter, for example semi-buried or completely buried (pit). More generally, this type of enclosure is therefore provided in an air space or/and at least partially in the form of pits. Feet (pf) or another bottom support can then be provided to keep it stable in the bottom of the enclosure.

Ce type d'installation mono-pot est souvent le plus simple que les métallurgistes prévoient par exemple dans une ligne de galvanisation. Lors d'une maintenance du pot, il est alors nécessaire d'arrêter le défilement du produit dans le pot, et donc d'arrêter la production de la ligne jusqu'à plusieurs jours, de façon à vider, nettoyer, remplir voire complétement vider puis retirer le pot de l'enceinte pour un remplacement avec un pot nettoyé ou neuf. Il en ressort que des pertes de production sont conséquentes. De plus, le retrait de pot de l'enceinte, si il doit être maintenu et donc retiré puis replacé dans l'enceinte est à risque, car sa structure (réfractaire) est sujette à des déformations ou des fissures lors d'un déplacement insuffisamment maitrisé ou nécessitant des opérations d'élévation, descente ou/et autres rotations du pot engendrant des instabilités.This type of single-pot installation is often the simplest that metallurgists provide for example in a galvanizing line. During maintenance of the pot, it is then necessary to stop the flow of the product in the pot, and therefore to stop the production of the line for up to several days, so as to empty, clean, fill or even completely empty. then remove the pot from the enclosure for replacement with a cleaned or new pot. It appears that production losses are substantial. In addition, the removal of pot from the enclosure, if it must be maintained and therefore removed and then replaced in the enclosure is at risk, because its structure (refractory) is subject to deformations or cracks when moved insufficiently controlled or requiring operations of raising, lowering and/or other rotations of the pot generating instabilities.

C'est pourquoi de tels métallurgistes cherchent à pouvoir simplifier les étapes de maintenance de pot. De plus, ils requièrent qu'une réalisation visant une modification de leur installation initiale (telle que celle à mono-pot) se déroule sous une durée minimale, afin de ne pas diminuer leur productivité finale.This is why such metallurgists seek to be able to simplify pot maintenance steps. In addition, they require that a realization aiming at a modification of their initial installation (such as that with mono-pot) takes place within a minimum duration, so as not to reduce their final productivity.

A ces titres et plus généralement, la présente invention prévoit alors une méthode d'adaptation d'une installation comprenant un premier pot de revêtement (p1) d'un produit à défilement (pr_ON) longitudinal, ledit premier pot étant disposé dans une première enceinte (e1), et caractérisée par :

  • une première étape de création (fig. 1A, 1B) d'une deuxième enceinte (e2) décalée latéralement de la première enceinte suivant un premier axe (X),
  • une deuxième étape d'assemblage (fig. 2A, 2B) d'un deuxième pot de revêtement (p2) dans la deuxième enceinte,
  • une troisième étape de création (fig. 3A, 3B) d'une troisième enceinte (e3) englobant au moins la première enceinte suivant un second axe (Y, ici identique ou du moins parallèle au premier axe X) et destinée à être mise en jonction latérale avec la deuxième enceinte.
In these respects and more generally, the present invention then provides a method for adapting an installation comprising a first coating pot (p1) of a product with longitudinal scrolling (pr_ON), said first pot being placed in a first enclosure (e1), and characterized by:
  • a first step of creation ( fig. 1A, 1B ) a second enclosure (e2) offset laterally from the first enclosure along a first axis (X),
  • a second assembly step ( fig. 2A, 2B ) of a second pot of coating (p2) in the second chamber,
  • a third stage of creation ( fig. 3A, 3B ) of a third enclosure (e3) encompassing at least the first enclosure along a second axis (Y, here identical or at least parallel to the first axis X) and intended to be placed in lateral junction with the second enclosure.

Les axes orthogonaux (X, Y, Z) sont représentés aux figures 1A et 1B. Les axes (X, Y) étant horizontaux et (Z) vertical.The orthogonal axes (X, Y, Z) are shown in figures 1A and 1B . The axes (X, Y) being horizontal and (Z) vertical.

Les enceintes visées par l'invention sont prévues dans un espace aérien ou/et au moins partiellement sous forme de simples fosses, de sorte qu'elles soient partiellement ou complétement sous-terraines par rapport au sol (so). Elles sont bien-sûr ouvertes en partie supérieure pour permettre à un pot d'y être placé, puis elles peuvent être recouvertes lors du mode fonctionnel de revêtement.The enclosures covered by the invention are provided in an air space and/or at least partially in the form of simple pits, so that they are partially or completely underground with respect to the ground (so). They are of course open at the top to allow a pot to be placed there, then they can be covered during the functional coating mode.

En particulier, la première étape de création (fig. 1A, 1B) de la deuxième enceinte prévoit qu'elle se déroule pendant que le produit est en défilement continu (pr_ON) dans le premier pot (p1) et donc la production est ainsi maintenue active durant ladite première étape. Des moyens de protection entre les deux enceintes (e1, e2) sont prévus pour empêcher toute pollution du premier pot (p1) par des projections provenant de la zone de réalisation de la deuxième enceinte. Des moyens de création de la deuxième enceinte (reprise ou démolition de dalles existantes, excavations, enfoncement de piliers, etc.) sont prévus pour être anti-vibratoires au niveau de la première enceinte (par exemple par utilisation de découpes à disque diamant) de sorte que la qualité du revêtement en cours dans la première enceinte ne soit pas impactée négativement.In particular, the first creation step ( fig. 1A, 1B ) of the second chamber provides that it takes place while the product is continuously scrolling (pr_ON) in the first pot (p1) and therefore production is thus kept active during said first stage. Protection means between the two enclosures (e1, e2) are provided to prevent any pollution of the first pot (p1) by projections originating from the area where the second enclosure is made. Means for creating the second enclosure (recovery or demolition of existing slabs, excavations, driving in pillars, etc.) are provided to be anti-vibration at the level of the first enclosure (for example by using diamond disc cutouts) of so that the quality of the current coating in the first enclosure is not negatively impacted.

Une fois la première étape finalisée, la première et la deuxième enceintes sont toujours séparées par une paroi verticale (destinée à être supprimée pour la future mise en jonction latérale). Des opérations de réalisation menées dans la deuxième enceinte ne peuvent donc pas nuire aux opérations de revêtement actif dans la première enceinte. La deuxième étape d'assemblage (fig. 2A, 2B) d'un deuxième pot de revêtement (p2) dans la deuxième enceinte peut ainsi commencer pendant que le produit est toujours en défilement continu (pr_ON) dans le premier pot (p1) et donc la production est ainsi maintenue active durant ladite deuxième étape. Il est aussi prévu de réaliser le deuxième pot (p2, fig. 2B) avantageusement mobile, en particulier selon respectivement le premier axe (x).Once the first stage has been finalized, the first and second enclosures are still separated by a vertical wall (intended to be removed for the future lateral joining). Implementation operations carried out in the second enclosure cannot therefore harm the active coating operations in the first enclosure. The second assembly step ( fig. 2A, 2B ) of a second pot of coating (p2) in the second enclosure can thus begin while the product is still in continuous scrolling (pr_ON) in the first pot (p1) and therefore production is thus kept active during said second step. It is also planned to make the second pot (p2, fig. 2B ) advantageously movable, in particular along the first axis (x) respectively.

Une fois la deuxième étape finalisée, la paroi verticale entre la première et la deuxième enceintes est supprimée pour la future mise en jonction latérale des dites enceintes. Ces opérations de réalisation sont menées depuis la deuxième enceinte pour ne pas nuire aux opérations de revêtement actif dans la première enceinte. La troisième étape de création (fig. 3A, 3B) d'une troisième enceinte (e3) englobant au moins la première enceinte (e1) et ici la deuxième enceinte (e2) suivant l'axe (X) est ainsi réalisée pendant que le produit est toujours en défilement continu (pr_ON) dans le premier pot (p1) et donc la production est ainsi maintenue active durant ladite troisième étape.Once the second stage has been finalized, the vertical wall between the first and the second enclosures is removed for the future lateral joining of said enclosures. These production operations are carried out from the second enclosure so as not to interfere with the active coating operations in the first enclosure. The third stage of creation ( fig. 3A, 3B ) of a third enclosure (e3) encompassing at least the first enclosure (e1) and here the second enclosure (e2) along the axis (X) is thus produced while the product is still in continuous scrolling (pr_ON) in the first pot (p1) and therefore production is thus kept active during said third step.

Il est à noter que la première, la deuxième et la troisième étapes selon la méthode d'adaptation de l'installation peuvent fort avantageusement se dérouler alors que le produit est en défilement continu (pr_ON), c'est-à-dire libre de tout arrêt de production du produit à défilement en cours de revêtement.It should be noted that the first, the second and the third stages according to the adaptation method of the installation can very advantageously take place while the product is in continuous scrolling (pr_ON), that is to say free from any production stoppage of the scrolling product during coating.

Alternativement, il est aussi possible d'arrêter la production du produit à défilement en cours de revêtement, si il est prévu de réaliser des modifications dimensionnelles de la première enceinte, par exemple si il était envisagé d'y placer un pot de plus grande taille que le premier pot (p1) initial., et même plusieurs emplacements de pots juxtaposés à insérer dans la nouvelle première enceinte.Alternatively, it is also possible to stop the production of the scrolling product being coated, if it is planned to carry out dimensional modifications of the first enclosure, for example if it were planned to place therein a larger pot than the initial first pot (p1), and even several juxtaposed pot locations to be inserted in the new first enclosure.

Suite à la troisième étape (fig. 3A, 3B), figures 4A, 4B, 5A, 5B présentent des vues de dessus (type A) et de côté (type B) de la première installation lors d'étapes de remplacement du premier pot (p1) par le deuxième pot (p2). Cette étape de remplacement d'un pot requiert un arrêt de défilement (pr_OFF) du produit dans le deuxième pot, afin de pouvoir le vider et l'extraire de la troisième enceinte (e3). Une fois l'extraction effectué, le deuxième pot mobile est déplacé horizontalement et mono-directionnellement à l'emplacement de l'ancien premier pot, par exemple par un simple système de rails rectilignes posés dans le fond de l'enceinte. Les figures 5A et 5B présentent alors une remise en fonction du défilement du produit (pr_ON) dans le deuxième pot (p2), l'emplacement initial du deuxième pot (fig. 4A, 4B) restant vacant.Following the third step ( fig. 3A, 3B), figures 4A, 4B , 5A, 5B show top (type A) and side (type B) views of the first installation during the steps of replacing the first pot (p1) with the second pot (p2). This step of replacing a jar requires a scrolling stop (pr_OFF) of the product in the second jar, in order to be able to empty it and extract it from the third enclosure (e3). Once the extraction has been carried out, the second mobile pot is moved horizontally and mono-directionally to the location of the former first pot, for example by a simple system of rectilinear rails placed in the bottom of the enclosure. The figures 5A and 5B then present a resetting of the scrolling of the product (pr_ON) in the second pot (p2), the initial location of the second pot ( fig. 4A, 4B ) remaining vacant.

Avantageusement, cet emplacement vacant permet de pouvoir y installer un nouveau, troisième pot (p3) mobile, telles que les figures 6A, 6B le présentent sous forme de vues de dessus (type A) et de côté (type B) de la première installation alors à nouveau sous forme bi-pots. Il est ainsi possible de prévoir le futur (troisième) pot de remplacement du second pot (p2) en avance de la phase de maintenance du dit second pot. Il est aussi à noter que cette pré-réalisation du troisième pot se déroule avantageusement, alors que le produit est en défilement continu (pr_ON), c'est-à-dire libre de tout arrêt de production du produit à défilement en cours de revêtement.Advantageously, this vacant location makes it possible to install a new, third mobile pot (p3) therein, such as the Figures 6A, 6B present it in the form of top (type A) and side (type B) views of the first installation then again in bi-pot form. It is thus possible to predict the future (third) replacement pot of the second pot (p2) in advance of the maintenance phase of said second pot. It should also be noted that this pre-production of the third pot takes place advantageously, while the product is in continuous scrolling (pr_ON), that is to say free of any stoppage of production of the scrolling product during coating.

Cette installation de type bi-pots dans une enceinte à deux emplacements de pots apporte ainsi une amélioration considérable tant dans sa réalisation sous les étapes décrites précédemment que dans la maintenance des pots, car seule l'étape de remplacement d'un pot par un autre pot requiert un court arrêt de production du produit à défilement en cours de revêtement, par exemple réalisable en moins d'un jour.This installation of the bi-pot type in an enclosure with two pot locations thus provides a considerable improvement both in its implementation under the steps described above and in the maintenance of the pots, because only the step of replacing one pot with another pot requires a short stoppage of production of the scrolling product during coating, for example achievable in less than a day.

De plus, sachant que le (troisième ou deuxième) pot pour remplacer le (deuxième ou premier) pot à évacuer (ou maintenir) est simplement et fort stablement déplacé horizontalement et mono-directionnellement à l'emplacement de l'ancien (premier) pot, des risques de déformations ou de fissures de pot sont écartés.Moreover, knowing that the (third or second) pot to replace the (second or first) pot to be evacuated (or maintained) is simply and very stably moved horizontally and mono-directionally to the location of the old (first) pot , risks of deformations or pot cracks are ruled out.

A partir de l'installation décrite précédemment, il est encore possible de pouvoir l'améliorer à la demande d'un métallurgiste et si un aménagement d'une troisième enceinte de plus grande taille est réalisable. La méthode selon l'invention peut alors être appliquée comme précédemment à une installation telle qu'aux fig. 1A, 1B, 2A, 2B, 3A, 3B,..., 6A, 6B disposant de deux pots mobiles (au lieu de d'un pot mobile et un pot fixe sur pieds).From the installation described above, it is still possible to be able to improve it at the request of a metallurgist and if a development of a third enclosure of larger size is feasible. The method according to the invention can then be applied as before to an installation such as fig. 1A, 1B, 2A, 2B, 3A, 3B ,..., 6A, 6B with two mobile pots (instead of a mobile pot and a fixed pot on feet).

A ce titre, les figures 7A, 7B, 8A, 8B présentent des vues de dessus et de côté d'une installation dite « étendue » suite à des étapes de réalisation plus étendue de l'installation de la figure 1A, 1B, ..., 6A, 6B et comprenant finalement au moins un premier pot (p'1 = p2) et, si prévu, un deuxième pot (p2') disposés dans une première enceinte (e1' = e3) à deux emplacements de pots (bi-pots).As such, the Figures 7A, 7B, 8A, 8B present top and side views of a so-called "extended" installation following more extensive stages of the installation of the figure 1A, 1B , ..., 6A, 6B and finally comprising at least a first pot (p'1 = p2) and, if provided, a second pot (p2') arranged in a first enclosure (e1' = e3) at two pot locations (bi-pots).

La méthode selon l'invention prévoit alors de générer un emplacement libre pour un pot, comme aux figures 1A, 1B. Plus généralement, il est remis en œuvre la méthode d'adaptation d'une installation comprenant un premier pot de revêtement (p1') d'un produit à défilement longitudinal, ledit premier pot étant disposé dans une première enceinte (e1') à deux emplacement de pots, et caractérisée par :

  • une première étape de création (fig. 7A, 7B) d'une deuxième enceinte (e2') décalée latéralement de la première enceinte suivant un premier axe (X),
  • une deuxième étape d'assemblage (fig. 7A, 7B) d'un deuxième pot de revêtement (p2') dans la première enceinte, si celui-ci n'était pas présent dans la première enceinte (e1'),
  • une troisième étape de création (fig. 8A, 8B) d'une troisième enceinte (e3') englobant ici au moins la première enceinte (e1') et la deuxième enceinte (e2') suivant un second axe ici identique au premier axe (X) et destinée à être mise en jonction latérale avec la deuxième enceinte.
The method according to the invention then provides for generating a free space for a pot, as in the Figures 1A, 1B . More generally, the method of adapting an installation comprising a first coating pot (p1') for a longitudinally moving product is reimplemented, said first pot being placed in a first enclosure (e1') with two location of pots, and characterized by:
  • a first step of creation ( fig. 7A, 7B ) a second enclosure (e2') offset laterally from the first enclosure along a first axis (X),
  • a second assembly step ( fig. 7A, 7B ) of a second pot of coating (p2') in the first enclosure, if the latter was not present in the first enclosure (e1'),
  • a third stage of creation ( fig. 8A, 8B ) of a third enclosure (e3') including here at least the first enclosure (e1') and the second enclosure (e2') along a second axis here identical to the first axis (X) and intended to be placed in lateral junction with the second enclosure.

Les avantages des première, deuxième, troisième étapes sont identiques à ceux déjà décrits aux figures 1A, 1B,..., 3A, 3B. En particulier, la réalisation de l'installation dite « étendue » n'impacte que très brièvement la productivité de l'installation, uniquement au remplacement rapide de pot par un autre (fig. 9A, 9B).The advantages of the first, second and third stages are identical to those already described in Figures 1A, 1B,..., 3A, 3B . In particular, the realization of the so-called "extended" installation only has a very brief impact on the productivity of the installation, only when the pot is quickly replaced by another ( fig. 9A, 9B ).

En particulier, il est toujours à noter que la première, la deuxième et la troisième étapes selon la méthode d'adaptation de l'installation dite « étendue » peuvent fort avantageusement se dérouler alors que le produit est en défilement continu (pr_ON) ici dans le premier pot (p1'), c'est-à-dire libre de tout arrêt de production du produit à défilement en cours de revêtement.In particular, it should always be noted that the first, second and third stages according to the so-called "extended" installation adaptation method can very advantageously take place while the product is in continuous scrolling (pr_ON) here in the first pot (p1'), that is to say free of any production stoppage of the scrolling product during coating.

Les premier et deuxième pots de revêtements (p1', p2') sont aussi avantageusement prévus mobiles dans la troisième enceinte (e3'), en particulier selon respectivement ici un seul axe (X, voir fig. 1A, 1B), donc selon une voie monodirectionelle et horizontale, permettant d'écarter des déformations ou fissures des pots en déplacement.The first and second pots of coatings (p1', p2') are also advantageously provided to be mobile in the third enclosure (e3'), in particular according respectively here to a single axis (X, see fig. 1A, 1B ), so along a unidirectional path and horizontal, making it possible to rule out deformations or cracks in the moving pots.

Enfin, les figures 9A, 9B, 10A, 10B présentent des vues de dessus (type A) et de côté (type B) de l'installation dite « étendue » lors d'étapes de remplacement du premier pot (p1') à maintenir par le deuxième pot (p2') à mettre en production. Principalement, cette étape est la seule nécessitant un arrêt de de production du produit à défilement (pr_OFF) en cours de revêtement. Cette étape à déjà été décrite analoguement aux figures 4A, 4B, 5A, 5B (pots p1, p2). La seule différence réside en ce que cette installation dite « étendue » prévoit au final trois emplacements de pot et deux pots mobiles. L'avantage s'y rattachant est que lors d'une maintenance d'un premier pot en défilement continu (pr_ON), l'autre deuxième pot peut être maintenu et préparé à l'avance de ladite maintenance, sans gêner la production du produit à défilement en cours de revêtement dans le premier pot. Ceci s'applique aussi vice-versa pour le premier et le deuxième pots, car les pots sont déplacés simultanément en binôme depuis les emplacements de pots gauche-centre vers les emplacements de pots centre-droite (fig. 9A, 9B, 10A, 10B), et vice-versa. Les durées de maintenance de chacun des pots sont donc ici sans influence sur la productivité de l'installation étendue.Finally, the figures 9A, 9B, 10A, 10B present views from above (type A) and from the side (type B) of the so-called "extended" installation during the steps of replacing the first pot (p1') to be maintained by the second pot (p2') to be put in production. Mainly, this step is the only one requiring a production stop of the scrolling product (pr_OFF) during coating. This step has already been described similarly to Figures 4A, 4B , 5A, 5B (jars p1, p2). The only difference is that this so-called "extended" installation ultimately provides three pot locations and two mobile pots. The related advantage is that during a maintenance of a first pot in continuous scrolling (pr_ON), the other second pot can be maintained and prepared in advance of said maintenance, without interfering with the production of the product scroll being coated in the first pot. This also applies vice-versa for the first and second pots, as the pots are moved simultaneously in pairs from the left-center pot slots to the center-right pot slots ( fig. 9A, 9B, 10A, 10B ), and vice versa. The maintenance times for each of the pots therefore have no influence here on the productivity of the extended installation.

En plus, il est ici envisageable de prévoir des compositions différentes de métal liquide de revêtement dans chacun des deux pots. La préparation d'une composition différente se déroule sans gêner le revêtement continu sous l'autre composition.In addition, it is here possible to envisage providing different compositions of coating liquid metal in each of the two pots. The preparation of a different composition proceeds without interfering with the continuous coating under the other composition.

Figure 11 présente une vue de côté (type B) d'une installation dite « très étendue » suite à des étapes de réalisation plus étendue de l'installation dite « étendue » de la figure 8B, 9B ou 10B et comprenant finalement une enceinte finale où sont disposés au moins le premier pot, le deuxième pot, un troisième pot ajouté selon la méthode prévue pour l'invention et deux emplacements libres pour un pot, créés respectivement aussi selon la méthode prévue pour l'invention. Picture 11 presents a side view (type B) of a so-called "very extensive" installation following more extensive production stages of the so-called "extended" installation of the figure 8B , 9B or 10B and finally comprising a final enclosure where at least the first pot, the second pot, a third pot added according to the method provided for the invention and two free slots for a pot, created respectively also according to the method provided for the invention.

Analogiquement aux figures 8B, 9B, 10B, cette configuration d'installation « tri-pots » a les mêmes avantages que la configuration « bi-pots ».Analogously to figure 8B , 9B, 10B , this “tri-pot” installation configuration has the same advantages as the “bi-pot” configuration.

En plus, il est ici envisageable de prévoir des compositions différentes de métal liquide de revêtement dans au moins un ou deux des trois pots. La préparation d'une ou deux compositions différentes se déroule sans gêner le revêtement continu sous une autre composition.In addition, it is here possible to envisage providing different compositions of coating liquid metal in at least one or two of the three pots. The preparation of one or two different compositions proceeds without interfering with the continuous coating under another composition.

Figures 12A, 12B, 12C, 12D, 12E, 14F présentent des vues de dessus et de côté d'une installation dite « étendue orthogonalement» suite à des étapes de réalisation plus étendue de l'installation de la figure 5A, 5B ou 6A, 6B et comprenant finalement au moins un premier pot, un deuxième pot selon la méthode prévue pour l'invention et un emplacement libre pour un pot. Figures 12A, 12B , 12C, 12D, 12E , 14F show top and side views of a so-called "orthogonally extended" installation following more extensive production stages of the installation of the figure 5A, 5B or 6A, 6B and finally comprising at least a first pot, a second pot according to the method provided for the invention and a free space for a pot.

Plus précisément, la méthode selon l'invention est mise en œuvre en ce que une installation est réalisée comprenant un premier pot de revêtement (p1' = p2, fig. 5A) d'un produit à défilement actif (pr_ON) longitudinal, ledit premier pot étant disposé dans une première enceinte (e1' = e3, fig. 5A) à deux emplacements de pots, et caractérisée par :

  • une première étape de création (fig. 12B) d'une deuxième enceinte (e2') décalée latéralement de la première enceinte suivant un premier axe (Y) orthogonal au plan de défilement (X, Z) du produit,
  • une deuxième étape d'assemblage (fig. 12C) d'un deuxième pot de revêtement (p2') dans la deuxième enceinte,
  • une troisième étape de création (fig. 12D) d'une troisième enceinte (e3') englobant au moins la première enceinte (e1') s'étendant suivant un second axe (X) et la deuxième enceinte (e2') après avoir été mise en jonction latérale avec la deuxième enceinte, de sorte que la troisième enceinte forme une enceinte en forme de L comprenant trois emplacements de pots et deux pots mobiles horizontalement.
More specifically, the method according to the invention is implemented in that an installation is produced comprising a first coating pot (p1' = p2, fig. 5A ) of a product with active scrolling (pr_ON) longitudinally, said first pot being arranged in a first enclosure (e1' = e3, fig. 5A ) with two pot locations, and characterized by:
  • a first step of creation ( fig. 12B ) a second enclosure (e2') offset laterally from the first enclosure along a first axis (Y) orthogonal to the travel plane (X, Z) of the product,
  • a second assembly step ( fig. 12C ) of a second pot of coating (p2') in the second chamber,
  • a third stage of creation ( fig. 12D ) of a third enclosure (e3') including at least the first enclosure (e1') extending along a second axis (X) and the second enclosure (e2') after having been placed in lateral junction with the second enclosure, so that the third enclosure forms an L-shaped enclosure comprising three pot locations and two horizontally movable pots.

Les figures 12E et 12F représentent un changement du premier pot (p1') avec le deuxième pot (p2') par arrêt bref du défilement de produit (pr_OFF), suivi d'un déplacement horizontal mono-directionnel du premier pot depuis son emplacement sous le produit en arrêt de défilement (pr_OFF) vers un premier emplacement vacant juxtaposé, puis d'un déplacement horizontal mono-directionnel du deuxième pot depuis un second emplacement vacant vers l'emplacement sous le produit à remettre en défilement (pr_ON).The figures 12E and 12F represent a change of the first pot (p1') with the second pot (p2') by briefly stopping the scrolling of the product (pr_OFF), followed by a one-way horizontal movement of the first pot from its location under the product stopping scrolling (pr_OFF) to a first juxtaposed vacant location, then a one-way horizontal movement of the second pot from a second vacant location to the location under the product to be scrolled again (pr_ON).

En résumé pour toutes les figures permettant de bien comprendre la méthode d'adaptation d'installation selon l'invention, des configurations de dite « troisième » enceinte sont possibles en disposant des emplacements de pots successivement linéaires selon un axe ou/et orthogonaux selon deux axes perpendiculaires dont l'intersection est placée à l'endroit de revêtement de produit. Pour une configuration à trois emplacements de pots et deux pots par exemple, les premier et deuxième pots de revêtements sont prévus mobiles, en particulier selon respectivement le premier et le second axe (X, Y), ceux-ci étant alignés (voire parallèles) ou orthogonaux.In summary, for all the figures allowing a good understanding of the installation adaptation method according to the invention, so-called "third" enclosure configurations are possible by arranging successively linear pot locations along an axis or/and orthogonal along two perpendicular axes whose intersection is placed at the place of product coating. For a configuration with three pot locations and two pots, for example, the first and second coating pots are provided to be mobile, in particular along the first and second axes (X, Y) respectively, these being aligned (or even parallel) or orthogonal.

Afin d'accélérer la réalisation de l'installation, il est aussi envisageable de prévoir que la deuxième et la troisième étapes soient réalisées simultanément. Ceci requiert des moyens de protection identiques et supplémentaires à ceux mentionnés pour les figures 3A, 3B ou 8A, 8B ou 12D.In order to speed up the production of the installation, it is also conceivable to provide for the second and the third stages to be carried out simultaneously. This requires identical and additional means of protection to those mentioned for the Figures 3A, 3B Where 8A , 8B or 12D .

Dans la présente invention, la troisième enceinte est créée sous un dimensionnement comprenant au moins deux, idéalement trois ou quatre ou cinq, ou plus d'emplacements de pots de revêtement.In the present invention, the third enclosure is created under a dimensioning comprising at least two, ideally three or four or five, or more liner pot locations.

Il est alors aisé pour un homme réalisant des installations de revêtement de prévoir des extensions de troisièmes enceintes décrites comprenant plus de pots ou d'emplacements alignés ou perpendiculaires.It is then easy for a man carrying out coating installations to provide extensions of third enclosures described comprising more pots or aligned or perpendicular locations.

Enfin, une des installations réalisées par la méthode selon l'invention comprenant au moins le premier pot de revêtement en mode fonctionnel de revêtement de produit et le deuxième pot en mode d'assemblage, prévoit que les dits pots sont disposés mobiles dans la troisième enceinte, en particulier sous des trajectoires horizontales mono-directionnelles, alignées ou/et perpendiculaires.Finally, one of the installations produced by the method according to the invention comprising at least the first coating pot in functional product coating mode and the second pot in assembly mode, provides that said pots are arranged movably in the third enclosure , in particular under mono-directional, aligned or/and perpendicular horizontal trajectories.

Une telle installation réalisée prévoit alors un dimensionnement sous une des configurations suivantes :

  • o Deux emplacements de pots de revêtement et un ou deux pots mobiles mono-directionnellement selon un axe (X),
  • o Trois emplacements de pots de revêtement et deux pots mobiles mono-directionnellement selon un axe (X) ou deux axes perpendiculaires (X,Y),
  • o Quatre emplacements de pots de revêtement et deux ou trois pots mobiles mono-directionnellement selon un axe (X), sinon deux ou trois axes distincts (X,Y),
  • o Cinq emplacements de pots de revêtement et trois ou quatre pots mobiles mono-directionnellement selon un axe (X), sinon deux, trois ou quatre axes distincts (X,Y).
Such an installed installation then provides for sizing under one of the following configurations:
  • o Two coating pot locations and one or two mono-directionally mobile pots along an axis (X),
  • o Three locations of coating pots and two mono-directionally mobile pots along an axis (X) or two perpendicular axes (X,Y),
  • o Four locations of coating pots and two or three mono-directionally mobile pots along an axis (X), otherwise two or three distinct axes (X, Y),
  • o Five locations for coating pots and three or four mono-directionally mobile pots along an axis (X), otherwise two, three or four distinct axes (X,Y).

Les avantages liés à la réalisation de telles installations réalisées, à leur maintenance, et finalement à leur productivité sont directement ceux liés à la méthode d'adaptation de telles installations selon l'invention précédemment décrite.The advantages linked to the production of such installations, to their maintenance, and finally to their productivity are directly those linked to the method of adapting such installations according to the invention described above.
