Description

La présente invention concerne un dispositif d'arrosage adapté à une installation de laminage de bandes métalliques en défilement, ainsi qu'une méthode d'extraction/introduction dudit dispositif d'arrosage et de guidage hors/dans ladite cage de laminage, selon le préambule des revendications 1 et 13.The present invention relates to a watering device adapted to a rolling strip metal striping installation, as well as a method for extracting / introducing said watering and guiding device out of / into said rolling stand, according to the preamble claims 1 and 13.

En particulier, l'invention se rapporte à la lubrification, ainsi qu'au refroidissement de la bande métallique et d'éléments liés au laminage à froid de ladite bande en défilement continu ou réversible dans au moins une cage de laminage ou laminoir d'une installation de laminage. Notamment, lesdits éléments font référence à un ensemble de cylindres superposés ayant des axes longitudinaux parallèles et placés sensiblement dans au moins un même plan perpendiculaire à la direction de défilement de la bande. L'axe longitudinal d'un desdits cylindres est défini comme un axe instantané de rotation, parallèle à une génératrice du cylindre et passant par le centre de masse dudit cylindre. De manière plus particulière, la présente invention a trait au laminage de certains alliages métalliques nécessitant l'utilisation de cylindres de laminage de petit diamètre, comme par exemple les aciers inoxydables, les aciers au silicium, ou encore certains alliages non ferreux. Ces alliages métalliques sont laminés dans des installations comportant au moins une cage de laminage à cylindres multiples comme, par exemple, des laminoirs de type 12-High ou 20-High, c'est-à-dire équipés de 12 ou de 20 cylindres.In particular, the invention relates to the lubrication, as well as the cooling of the metal strip and elements related to the cold rolling of said strip in continuous or reversible running in at least one rolling stand or rolling mill of a rolling installation. In particular, said elements refer to a set of superimposed cylinders having parallel longitudinal axes and placed substantially in at least one plane perpendicular to the running direction of the strip. The longitudinal axis of one of said cylinders is defined as an instantaneous axis of rotation, parallel to a generatrix of the cylinder and passing through the center of mass of said cylinder. More particularly, the present invention relates to the rolling of certain metal alloys requiring the use of small diameter rolling rolls, such as stainless steels, silicon steels, or some non-ferrous alloys. These metal alloys are rolled in plants comprising at least one rolling mill roll stand, such as, for example, 12-high or 20-high rolling mills, that is to say equipped with 12 or 20 rolls.

De manière connue, les cylindres de laminage de petit diamètre d'une cage de laminage n'ont pas une rigidité suffisante pour résister sans fléchir aux efforts de laminage. Ils sont donc soutenus dans la cage de laminage par des cylindres et des galets d'appui ou de soutien. Un exemple typique de laminoir 20-High est présenté en Figure 1. Ce dernier se compose d'un assemblage supérieur de dix cylindres de laminage et d'un assemblage inférieur de dix cylindres de laminage, chacun des assemblages comportant, selon une structure pyramidale ou en grappe, un cylindre de travail 3, 3' en contact avec la bande 2 à laminer et soutenu par deux cylindres de soutien intermédiaires 4, 4', eux-mêmes soutenus par trois cylindres d'appui intermédiaires 5, 5a, 5', 5'a, eux-mêmes soutenus par quatre rangées de galets d'appui 6, 6', chaque rangée de galets d'appui étant constituée d'une pluralité de galets d'appui et de sellettes montés en alternance sur un unique axe porteur de galets, chaque galet d'appui étant notamment bordé par deux sellettes. Chaque rangée de galets d'appui 6, 6' est de plus positionnée et fixée au châssis 1 de la cage de laminage au moyen desdites sellettes 7 qui permettent une reprise des efforts résultant du laminage par les cylindres de travail 3, 3', ainsi qu'un positionnement par rapport audit châssis 1 de la cage de laminage des rangées de galets d'appui 6, 6' qu'elles maintiennent.In known manner, the rolls of small diameter rolling of a rolling stand do not have sufficient rigidity to withstand without bending the rolling forces. They are therefore supported in the roll stand by cylinders and support rollers or support. A typical example of a 20-High rolling mill is presented in Figure 1 . The latter consists of an upper assembly of ten rolling rolls and a lower assembly of ten rolling rolls, each of the assemblies comprising, in a pyramidal or cluster structure, a working roll 3, 3 'in contact with the strip 2 to be rolled and supported by two intermediate support rollers 4, 4 ', themselves supported by three intermediate support rollers 5, 5a, 5', 5'a, themselves supported by four rows of rollers d support 6, 6 ', each row of support rollers consisting of a plurality of support rollers and saddles alternately mounted on a single axis carrying rollers, each support roller being in particular bordered by two saddles . Each row of support rollers 6, 6 'is furthermore positioned and fixed to the frame 1 of the rolling stand by means of said saddles 7 which allow the forces resulting from rolling to be taken up by the working rolls 3, 3', and that positioning relative to said frame 1 of the roll stand rows of support rollers 6, 6 'they maintain.

Afin de faciliter le défilement et le laminage de la bande 2 entre les cylindres de travail 3, 3', l'entrefer des cylindres de laminoirs à froid est arrosé et lubrifié. Pour cela, on procède à un arrosage de fluide lubrifiant sur la bande à laminer et sur la surface des cylindres de travail. Dans certains cas, le fluide d'arrosage joue également un rôle important dans l'évacuation des calories produites dans l'entrefer des cylindres par la réduction de la bande et sa déformation plastique. Il est ainsi de pratique courante, en laminage à froid, de refroidir les cylindres de travail par arrosage sous pression avec un fluide d'arrosage caloporteur et lubrifiant. Généralement, des systèmes comportant des buses d'arrosages permettent d'arroser au moins une partie de la bande ou une partie des cylindres avec ledit fluide d'arrosage caloporteur et lubrifiant.In order to facilitate the scrolling and rolling of the strip 2 between the working rolls 3, 3 ', the air gap of the rolls of cold rolling mills is sprinkled and lubricated. For this purpose, a lubrication fluid is sprayed on the strip to be rolled and on the surface of the working rolls. In some cases, the watering fluid also plays an important role in the evacuation of the calories produced in the air gap of the cylinders by the reduction of the band and its plastic deformation. It is thus common practice, in cold rolling, to cool the working cylinders by watering under pressure with coolant coolant and lubricant. Generally, systems comprising watering nozzles make it possible to water at least part of the strip or part of the rolls with said coolant and lubricant coolant fluid.

Dans le cas d'un laminoir de type duo, quarto ou sexto classique, l'arrosage des cylindres de travail est facilement réalisable, car l'accessibilité aux cylindres et à la bande est excellente. Par contre, la conception très compacte des laminoirs multicylindres, notamment de type 12- ou 20-High, est telle que l'espace disponible pour un dispositif d'arrosage des cylindres de travail est très restreint. Néanmoins, des dispositifs d'arrosage permettant un arrosage de la bande et des cylindres de travail sont connus de l'homme du métier, comme par exemple pour un laminoir 20-High. En effet, en référence à la Figure 1, un tel dispositif d'arrosage comprend notamment des tables d'arrosage 11, 11', 12, 12' comportant une partie fixe 11A, 11A', 12A, 12A', dite table fixe et montée en porte à faux, solidaire au châssis 1 de la cage de laminage, et comprenant des buses d'arrosage destinées à arroser essentiellement la bande 2, et une partie articulée 11B, 11B', 12B, 12B', dite table articulée, comprenant des buses d'arrosage destinées essentiellement à l'arrosage des cylindres de travail 3, 3'. Au total, quatre tables d'arrosage 11, 11', 12, 12' sont disposées dans la cage de laminage, respectivement une table d'arrosage 11 inférieure en entrée de cage de laminage et une table d'arrosage 12 inférieure en sortie de cage de laminage permettent d'arroser la partie inférieure de la bande 2 et le cylindre de travail inférieur 3, et une table d'arrosage 11' supérieure en entrée de cage de laminage et une table d'arrosage 12' supérieure en sortie de cage de laminage permettent d'arroser la partie supérieure de la bande 2 et le cylindre de travail supérieur 3'. En plus de leur fonction d'arrosage, les dispositifs d'arrosage ont une fonction de guidage et de protection. En effet, les tables fixes en entrée de cage de laminage permettent de guider une extrémité amont de bande à laminer lorsque cette dernière entre dans la cage de laminage, tout en protégeant les cylindres de laminoir et les buses d'arrosage situés en entrée ou en sortie de la cage de laminage de dégâts pouvant être provoqués, par exemple, par un bourrage de tôle ou une rupture de bande.In the case of a typical duo, quarto or sexto rolling mill, the watering of the work rolls is easily achievable because the accessibility to the rolls and to the band is excellent. On the other hand, the very compact design of the multicylinder mills, particularly of the 12- or 20-high type, is such that the space available for a device for spraying the work rolls is very limited. Nevertheless, irrigation devices for watering the band and working rolls are known to those skilled in the art, such as for a 20-High mill. Indeed, with reference to the Figure 1 such a watering device comprises in particular watering tables 11, 11 ', 12, 12' comprising a fixed portion 11A, 11A ', 12A, 12A', said fixed table and mounted cantilevered, secured to the frame 1 of the rolling stand, and comprising watering nozzles intended to essentially water the strip 2, and an articulated portion 11B, 11B ', 12B, 12B', said hinged table, comprising spray nozzles intended essentially for the purpose of watering of the work rolls 3, 3 '. In total, four watering tables 11, 11 ', 12, 12' are disposed in the rolling stand, respectively a lower watering table 11 at the rolling mill inlet and a lower watering table 12 at the outlet of the rolling stand. rolling cage used to water the lower portion of the strip 2 and the lower working roll 3, and a top 11 'watering table at the inlet of the rolling stand and a top 12' watering table at the exit of the cage rolling to irrigate the upper portion of the strip 2 and the upper working roll 3 '. In addition to their watering function, watering devices have a guiding and protective function. Indeed, the fixed tables at the milling cage inlet make it possible to guide an upstream end of the strip to be rolled when the latter enters the rolling stand, while protecting the rolling mill rolls and the watering nozzles located at the inlet or outlet. output of the rolling mill from damage that can be caused, for example, by a sheet-stuffing or breaking tape.

Dans la pratique courante, il est nécessaire de procéder à un nettoyage/remplacement ou à un contrôle périodique des buses d'arrosage de chaque table d'arrosage. Malheureusement, les dispositifs d'arrosage connus de l'homme du métier ne permettent pas un accès facile auxdites buses d'arrosages ainsi qu'une inspection de maintenance aisée des équipements. En effet, même après démontage des cylindres de la cage de laminage, la conception de la table d'arrosage empêche tout accès aisé aux buses d'arrosage de ladite partie fixe de la table d'arrosage. Ainsi le contrôle ou le nettoyage/remplacement des buses d'arrosage des systèmes d'arrosage connus de l'homme du métier, et l'entretien en général desdits systèmes d'arrosage, sont des opérations de maintenance complexe, longue à réaliser, et donc économiquement défavorables. De plus, les tables d'arrosage connues de l'homme du métier présentent un autre inconvénient qui est une faible rigidité résultant de leur montage en porte à faux.In normal practice, it is necessary to carry out a cleaning / replacement or a periodic control of the watering nozzles of each watering table. Unfortunately, the watering devices known to those skilled in the art do not allow easy access to said spray nozzles and an easy maintenance inspection equipment. Indeed, even after disassembly of the cylinders of the rolling stand, the design of the watering table prevents easy access to the spray nozzles of said fixed part of the watering table. Thus the control or the cleaning / replacement of irrigation nozzles of watering systems known to those skilled in the art, and the maintenance in general of said watering systems, are complex maintenance operations, long to carry out, and therefore economically unfavorable. In addition, the watering tables known to those skilled in the art have another disadvantage that is low rigidity resulting from their mounting cantilever.

Un but de la présente invention est de proposer un dispositif d'arrosage d'une cage de laminage multicylindre à froid d'une bande métallique capable de résoudre les inconvénients susmentionnés, tout en garantissant un guidage de la bande et une protection des cylindres de laminoir et des buses d'arrosage et une amélioration très significative de la maintenance nécessaire à l'exploitation productive du laminoir.An object of the present invention is to provide a cooling device for a multicylinder cold rolling mill of a metal strip capable of solving the aforementioned drawbacks, while guaranteeing a guiding of the strip and a protection of the rolling mill rolls. and watering nozzles and a very significant improvement in the maintenance required for the productive operation of the rolling mill.

Un ensemble de sous-revendications présente également des avantages de l'invention.A set of subclaims also has advantages of the invention.

Préférentiellement, ledit connecteur est monté côté moteur lorsque ladite table fixe est montée dans la cage de laminage, mais un tel connecteur peut également être monté à chaque extrémité de ladite table fixe. Il s'agit par exemple d'un connecteur rapide, par exemple du type canule télescopique. Par côté moteur, il est fait référence au côté de la cage de laminage en vis-à-vis duquel sont situés notamment les moteurs d'entrainement des cylindres de laminage, par opposition au côté opérateur où se trouve un opérateur.
The present invention relates to a watering device comprising a plurality of nozzles for lubricating and cooling the air gap of a multi-cylinder rolling stand intended for rolling metal strips, characterized in that said watering device comprises
  • an elongated fixed watering table configured to be secured to, and in particular supported on, a plurality of saddles of a row of support rollers of said rolling stand;
  • said fixed watering table comprising a fluid distribution network intended to convey a cooling fluid to said nozzles for said lubrication and said cooling of the band and / or said air gap, a connector for the connection of said network of distribution to a delivery network of said fluid, and fixing means, distributed in particular along its width, for its attachment, especially locally, said harnesses, preferably end harnesses of said fixed table. Preferably, said connector is mounted on the motor side when said fixed table is mounted in the rolling stand, but such a connector can also be mounted at each end of said fixed table. This is for example a quick connector, for example of the telescopic cannula type. By engine side, reference is made to the side of the rolling stand opposite which are located in particular the driving motors of the rolling rolls, as opposed to the operator side where there is an operator.

Préférentiellement, ledit dispositif d'arrosage selon l'invention comprend une table articulée de forme allongée, emboîtable, notamment par coulissement, dans une rainure, par exemple cylindrique, rectiligne, disposée d'un côté de ladite table fixe, sur au moins des zones préférentielles de toute sa longueur. En particulier, ladite table articulée comprend des buses destinées à un arrosage d'au moins un cylindre de travail, et préférentiellement, également destinées à un arrosage des cylindres intermédiaires et d'appuis voisins de la cage de laminage, un réseau de distribution dudit fluide destiné à un acheminement dudit fluide d'arrosage vers lesdites buses de la table articulée pour ladite lubrification et ledit refroidissement dudit cylindre de travail et préférentiellement, également destinées à un arrosage des cylindres intermédiaires et d'appuis voisins, et au moins un connecteur destiné à la connexion de son réseau de distribution (112) audit réseau d'amenée de fluide. A cette fin, ladite table articulée, et donc ses buses, sont en particulier réglables en position par un système de commande du mouvement de ladite table articulée, de façon à pouvoir être dirigées principalement en direction dudit cylindre de travail, et préférentiellement, également en direction desdits cylindres intermédiaires lorsque ladite table articulée est montée dans ladite cage de laminage. Préférentiellement, le réseau de distribution dudit fluide d'arrosage de ladite table fixe est indépendant du réseau de distribution dudit fluide d'arrosage de la table articulée. De plus, le connecteur de chaque réseau de distribution dudit fluide d'arrosage est notamment apte à être automatiquement accouplé audit réseau d'amenée dudit fluide d'arrosage lors d'une introduction de ladite rangée de galets d'appui et/ou de la table articulée dans ladite cage de laminage et/ou d'une fermeture d'une porte coté opérateur du châssis de la cage de laminage, et inversement, à être automatiquement découplé du réseau d'amenée lors d'un démontage de ladite rangée de galets d'appui ou de la dite table articulée et/ou d'une ouverture de ladite porte du châssis de la cage de laminage.Preferably, said sprinkler device according to the invention comprises a hinged table of elongated shape, nestable, in particular by sliding, in a groove, for example cylindrical, rectilinear, disposed on one side of said fixed table, on at least areas preferential throughout its length. In particular, said hinged table comprises nozzles intended for watering at least one working cylinder, and preferably also for watering the intermediate rolls and supports adjacent to the roll stand, a distribution network of said fluid. for routing said watering fluid to said nozzles of the hinged table for said lubrication and said cooling of said working roll and preferably also for watering the intermediate rolls and adjacent supports, and at least one connector for connecting its distribution network (112) to said fluid supply network. For this purpose, said hinged table, and therefore its nozzles, are in particular adjustable in position by a system for controlling the movement of said hinged table, so that it can be directed mainly towards said work roll, and preferably also in direction of said intermediate cylinders when said articulated table is mounted in said rolling stand. Preferably, the distribution network of said irrigation fluid of said fixed table is independent of the distribution network of said irrigation fluid of the articulated table. In addition, the connector of each distribution network of said coolant fluid is in particular adapted to be automatically coupled to said supply network of said coolant during introduction of said row of support rollers and / or the articulated table in said rolling stand and / or a closing of a door operator side the chassis of the rolling stand, and conversely, to be automatically decoupled from the supply network during disassembly of said row of support rollers or said articulated table and / or an opening of said door chassis of the rolling stand.

En particulier, ladite table articulée comprend au moins à une de ses extrémités, notamment positionnée côté moteur lorsqu'elle est montée dans ladite cage de laminage, un moyen de couplage à un système, par exemple mécanique, de transmission d'une commande de mouvement, par exemple motorisé, de ladite table articulée, ladite commande de mouvement émanant dudit système de commande du mouvement, positionné préférentiellement à l'extérieur de la cage de laminage côté moteur. Préférentiellement, ledit moyen de couplage audit système de transmission est apte à coupler automatiquement ledit réseau d'amenée audit réseau de distribution de fluide d'arrosage de ladite table articulée.In particular, said articulated table comprises at least at one of its ends, in particular positioned on the motor side when it is mounted in said rolling stand, means for coupling to a system, for example a mechanical system, for transmitting a motion control. , for example motorized, said articulated table, said motion control emanating from said motion control system, preferably positioned outside the rolling shaft on the motor side. Preferably, said coupling means to said transmission system is adapted to automatically couple said supply network to said irrigation fluid distribution network of said articulated table.

De plus, ledit moyen de couplage de la table articulée ainsi que son emboîtement avec ladite table fixe permettent avantageusement une extraction de la table fixe, notamment en position supérieure, hors de la cage de laminage, et respectivement son introduction dans la cage de laminage, indépendante d'une extraction, respectivement indépendant d'une introduction, de ladite table articulée hors, respectivement dans, ladite cage de laminage, et inversement. Ainsi, le démontage ou montage de la table fixe et de la table articulée sont préférentiellement indépendants l'un de l'autre et peuvent être facilement réalisés. En particulier, après couplage d'un dispositif d'extraction d'une rangée de galets d'appui à un dispositif de couplage de ladite table fixe dudit dispositif d'arrosage ou à un dispositif de couplage dudit axe porteur, ladite table fixe peut être extraite ou montée simultanément avec ladite rangée de galets d'appui à laquelle elle est fixée par coulissement longitudinal de ladite rangée de galets d'appui hors de la cage de laminage ou coulissement longitudinal dans la cage de laminage dans le cas de l'introduction. En particulier, ladite table fixe peut comprendre, à une de ses extrémités, notamment côté opérateur lorsque ledit dispositif d'arrosage est monté dans la cage de laminage, ledit dispositif de couplage adapté pour le couplage de la table fixe du dispositif d'arrosage au dispositif d'extraction de ladite rangée de galets d'appui. Ainsi, l'extraction/introduction d'une rangée de galets d'appui selon l'invention permet d'extraire simultanément ladite table fixe, notamment en positions supérieures, du dispositif d'arrosage selon l'invention.In addition, said coupling means of the articulated table and its interlocking with said fixed table advantageously allow extraction of the fixed table, particularly in the upper position, out of the rolling stand, and respectively its introduction into the rolling stand, independent of an extraction, respectively independent of an introduction, of said articulated table out respectively in said rolling stand, and vice versa. Thus, the disassembly or assembly of the fixed table and the hinged table are preferably independent of one another and can be easily made. In particular, after coupling of an extraction device of a row of support rollers to a coupling device of said fixed table of said sprinkler device or to a coupling device of said carrier shaft, said fixed table can be extracted or mounted simultaneously with said row of support rollers to which it is fixed by longitudinal sliding of said row of support rollers out of the roll cage or longitudinal sliding in the rolling stand in the case of introduction. In particular, said fixed table may comprise, at one of its ends, in particular the operator side when said sprinkler device is mounted in the rolling stand, said coupling device adapted for coupling the fixed table of the watering device to the extraction device of said row of support rollers. Thus, the extraction / introduction of a row of support rollers according to the invention makes it possible to simultaneously extract said fixed table, in particular in higher positions, from the watering device according to the invention.

La table fixe est préférentiellement destinée à un arrosage de la bande, en entrée ou en sortie de la cage de laminage, et a en particulier une géométrie adaptée à sa solidarisation avec lesdites sellettes, mais également, préférentiellement, ladite géométrie est adaptée à sa mise en appui avec lesdites sellettes. Préférentiellement, lesdits moyens de fixation sont répartis, par exemple de manière uniforme, selon la largeur de ladite table fixe, ou préférentiellement uniquement sur les sellettes d'extrémités de la rangée de galets d'appui. Selon un mode préférentiel de réalisation, seules les sellettes d'extrémités de la rangée de galets d'appui sont solidarisées à ladite table fixe, tandis que chacune des autres sellettes de ladite rangée de galets d'appui est simplement en contact ou appui avec ladite table fixe, de façon à renforcer sa rigidité. Avantageusement, la solidarisation de la table fixe du dispositif d'arrosage aux sellettes permet ladite extraction simultanée de l'ensemble formé de la rangée de galets d'appui et de ladite table fixe. De plus, ladite solidarisation de ladite table fixe auxdites sellettes grâce auxdits moyens de fixation permet de rigidifier ladite table fixe, car cette dernière comprend plusieurs points d'appui et de fixation non seulement sur sa longueur, mais aussi sur toute sa largeur.The fixed table is preferably intended for watering the strip at the inlet or outlet of the rolling stand, and in particular has a geometry adapted to its attachment to said saddles, but also, preferably, said geometry is adapted to its implementation. in support with said saddles. Preferably, said fixing means are distributed, for example uniformly, according to the width of said fixed table, or preferably only on the end saddles of the row of support rollers. According to a preferred embodiment, only the end saddles of the row of support rollers are secured to said fixed table, while each of the other saddles of said row of support rollers is simply in contact or support with said fixed table, so as to reinforce its rigidity. Advantageously, the fastening of the fixed table of the watering device to the saddles allows said simultaneous extraction of the assembly formed of the row of support rollers and said fixed table. In addition, said joining of said fixed table to said saddles by said fixing means makes it possible to stiffen said fixed table, since the latter comprises several points of support and fixing not only over its length, but also over its entire width.

La présente invention concerne également une rangée de galets d'appui comprenant une pluralité de galets d'appui et de sellettes montés, par exemple en alternance, sur un unique axe porteur de galets, chaque galet d'appui étant notamment bordé par deux sellettes, ladite rangée de galets d'appui étant destinée à reprendre les efforts de laminage résultant d'une cage de laminage multicylindre, par exemple de type 12- ou 20-High, caractérisée en ce qu'elle comprend ledit dispositif d'arrosage selon l'invention destiné à la lubrification et au refroidissement de la bande et/ou de l'entrefer de ladite cage de laminage et tel que précédemment décrit. Avantageusement, lesdites sellettes peuvent ainsi servir non seulement de support audit axe porteur des galets d'appui, mais également au dispositif d'arrosage selon l'invention, notamment à ladite table fixe et/ou à ladite table articulée dudit dispositif d'arrosage. En particulier, chaque rangée de galets d'appui de la cage de laminage dont un côté se trouve en vis-à-vis direct de la bande peut être équipée de ladite table fixe. Cette dernière est notamment apte à être solidarisée audit côté en vis-à-vis direct de la bande de façon à être au plus près de cette dernière. Par exemple, dans le cas d'une cage de laminage 20-High, les sellettes des rangées de galets d'appui les plus en amont et les plus en aval de la cage de laminage sont équipées du dispositif d'arrosage selon l'invention.The present invention also relates to a row of support rollers comprising a plurality of support rollers and saddles mounted, for example alternately, on a single roller bearing axis, each support roller being in particular bordered by two saddles, said row of support rollers being intended to take up the rolling forces resulting from a multi-cylinder rolling stand, for example of 12- or 20-High type, characterized in that it comprises said watering device according to the invention for lubricating and cooling the band and / or the air gap of said rolling stand and as previously described. Advantageously, said saddles can thus serve not only as a support for said bearing axis of the support rollers, but also for the watering device according to the invention, in particular at said fixed table and / or at said articulated table of said watering device. In particular, each row of bearing rollers of the rolling stand, one side of which is directly opposite the band, can be equipped with said fixed table. The latter is particularly adapted to be secured to said side directly vis-à-vis the band so as to be closer to the latter. For example, in the case of a 20-High rolling stand, the seats of the rows of support rollers furthest upstream and further downstream of the rolling stand are equipped with the watering device according to the invention. .

Préférentiellement, les sellettes de ladite rangée de galets d'appui sont configurées pour être liées par deux plaques de surfaces adjacentes destinées à prendre appui sur le châssis de la cage de laminage, lesdites plaques de surfaces adjacentes formant notamment un angle voisin de 90° l'une avec l'autre, et permettant entre autre d'une part une augmentation globale de la rigidité de ladite rangée de galets d'appui, et d'autre part l'extraction ou l'introduction de ladite rangée de galets d'appui et du dispositif d'arrosage par déplacement longitudinal, en particulier par coulissement, hors ou glissement dans la cage de laminage au moyen d'un dispositif d'extraction pouvant être accouplé au dispositif de couplage de ladite table fixe. Egalement, l'intégration d'une table fixe à ladite rangée de galets d'appui permet de faciliter le montage/démontage des rangées de galets d'appui supérieures, car ladite table fixe notamment pour les positions supérieures peut en particulier comprendre une zone d'appui en partie basse, i.e. la partie proche de la bande lorsque ladite table fixe est fixée auxdites sellettes dans la cage de laminage, ladite zone d'appui comprenant notamment au moins un guide longitudinal en forme de gorge pour le guidage latéral de ladite rangée de galets équipée du dispositif d'arrosage, ladite rainure 111 pouvant par exemple faire office dudit guide, et une surface plane d'appui pour le support de ladite rangée de galets d'appui lors de son extraction ou introduction au moyen d'un dispositif d'extraction de rangée de galets d'appuis, ledit guide étant apte à coopérer avec une partie dudit dispositif d'extraction étant équipé d'une forme complémentaire audit guide.Preferably, the saddles of said row of support rollers are configured to be connected by two adjacent surface plates intended to rest on the chassis of the rolling stand, said adjacent surface plates forming in particular an angle close to 90 ° C. with each other, and allowing, on the one hand, an increase overall of the rigidity of said row of support rollers, and secondly the extraction or introduction of said row of support rollers and the sprinkler device by longitudinal displacement, in particular by sliding, out or sliding in the rolling stand by means of an extraction device that can be coupled to the coupling device of said fixed table. Also, the integration of a fixed table to said row of support rollers facilitates the assembly / disassembly of the rows of upper support rollers, since said fixed table especially for the higher positions can in particular comprise a zone of support in the lower part, ie the part close to the band when said fixed table is fixed to said saddles in the rolling stand, said bearing area comprising in particular at least one longitudinal guide in the form of a groove for lateral guidance of said row of rollers equipped with the watering device, said groove 111 being able for example to act as said guide, and a flat bearing surface for supporting said row of support rollers during its extraction or introduction by means of a device extraction of row of support rollers, said guide being adapted to cooperate with a portion of said extraction device being equipped with a shape complementary to said guide.

La présente invention revendique également une cage de laminage à cylindres multiples, par exemple du type 12- ou 20-High, comprenant au moins une rangée de galets d'appui telle que précédemment décrite. Préférentiellement, une telle cage de laminage comprend de plus ledit système de commande dudit mouvement de ladite table articulée, ledit système de commande étant notamment disposé côté moteur, à l'extérieur de ladite cage de laminage et fixé à la porte coté moteur du châssis de la cage de laminage. Le positionnement côté moteur du système de commande permet avantageusement d'éviter par rapport à l'art antérieur une étape de démontage/montage de vérins dudit système de commande localisés préférentiellement coté opérateur et destinés à commander le mouvement de la table articulée et de flexibles destinés à alimenter le réseau de distribution (112) de ladite table articulée lors du démontage/montage du dispositif d'arrosage ou des rangées de galets d'appui. De plus, ledit positionnement libère également de la place côté opérateur et augmente la visibilité de la bande cage ouverte.The present invention also claims a multi-roll rolling stand, for example of the 12- or 20-High type, comprising at least one row of support rollers as previously described. Preferably, such a rolling stand further comprises said control system of said movement of said hinged table, said control system being in particular arranged on the motor side, outside said rolling stand and fixed to the engine side door of the frame of the rolling stand. The positioning on the motor side of the control system advantageously makes it possible to avoid, with respect to the prior art, a dismantling / mounting step of cylinders of said control system located preferentially operator side and intended to control the movement of the hinged table and hoses for supplying the distribution network (112) of said hinged table during disassembly / assembly of the watering device or rows of support rollers. In addition, said positioning also frees up the operator's side and increases the visibility of the open cage band.

  • un couplage d'un dispositif d'extraction d'une rangée de galets d'appui à un dispositif de couplage de ladite table fixe dudit dispositif d'arrosage, ou à un dispositif de couplage d'un axe porteur de ladite rangée de galets d'appui, ledit dispositif de couplage de ladite table fixe ou dudit axe porteur étant adapté pour permettre une extraction de ladite rangée de galets d'appui par déplacement longitudinal, i.e. parallèlement audit axe porteur;
