Description
La présente invention concerne une cage de laminoir multi cylindres de type monobloc, voire monobloc reconstitué par assemblage fixe ou précontraints ou par assemblage mobile de demi-cages supérieure et inférieure selon le préambule de la revendication 1.The present invention relates to a multi-cylinder rolling mill of monobloc type, or monoblock reconstituted by fixed assembly or preloaded or mobile assembly of upper and lower half-cages according to the preamble of claim 1.
Actuellement, il existe des cages de laminoir comprenant deux demi-cages supérieure et inférieure formant ainsi deux parties distinctes accouplées au moyen d'un guidage voué à amener verticalement les deux demi-cages vers leur position dite « serrée » de laminage. La présente invention consiste à augmenter sur une cage telle que du type 20 cylindres la gamme et combinaisons de diamètres de cylindres utilisables installés dans une cage "monobloc", monobloc reconstituées par assemblage fixe ou précontraints ou par assemblage mobile, ainsi que d'augmenter l'ouverture possible de cage entre cylindres de travail.Currently, there are rolling mill stands comprising two upper and lower half-stands thus forming two distinct parts coupled by means of a guide intended to bring the two half-stands vertically towards their so-called "tight" rolling position. The present invention consists in increasing on a cage such as cylinders the range and combinations of usable cylinder diameters installed in a "monoblock" cage, monobloc reconstituted by fixed or prestressed assembly or by movable assembly, as well as increasing possible opening of cage between work rolls.
Un exemple d'un tel laminoir monobloc est bien décrit au travers du document
Sachant que ce type de cage de laminoir de type monobloc reconstituée par assemblage doit si possible accueillir des gammes et combinaisons diverses de diamètre de cylindres (ou rouleaux) afin de s'adapter à des laminages de produits spécifiques, et que ces changements de cylindres doivent être effectués sans ouvrir la cage (c'est-à-dire sans même désolidariser les bâtis supérieur et inférieur dans le cas de deux demi-cages assemblées), il est difficile d'obtenir une ouverture suffisamment spacieuse pour interchanger les cylindres, introduire la bande à laminer, intervenir lors de maintenance ou incident de laminage en particulier en cas de casses de bande laminée.Knowing that this type of assembly-assembled monoblock-type rolling mill stand should, if possible, accommodate various ranges and combinations of roll diameter (or rolls) in order to adapt to specific product rolling, and that these roll changes must be made without opening the cage (that is to say without even separating the upper and lower frames in the case of two assembled half-cages), it is difficult to obtain an opening large enough to interchange the cylinders, introduce the rolling strip, to intervene during maintenance or rolling incident, in particular in case of breakage of rolled strip.
Un but de la présente invention est de permettre de pouvoir déplacer au moins une des rangées de galets d'appui d'un laminoir sous forme monobloc, voire monobloc reconstituées par assemblage fixe ou précontraints ou par assemblage mobile tout en lui assurant une course de déplacement suffisamment élevées entre une position serrée et une position ouverte de cage.An object of the present invention is to allow to be able to move at least one of the rows of support rollers of a rolling mill in monoblock form or monobloc reconstituted by fixed assembly or preloaded or movable assembly while providing a displacement stroke sufficiently high between a tight position and an open cage position.
L'invention propose ainsi une solution à partir d'une cage de laminoir multi cylindres comprenant selon une direction verticale une partie de bâti supérieur et une partie de bâti inférieur solidarisées sous forme monobloc, chacune des parties de bâti comprenant respectivement un ensemble de cylindres supérieurs et inférieurs, les dits cylindres supérieurs et inférieurs étant composés de rangées de galets d'appui destinés à créer des effets de pression sur des cylindres intermédiaires, eux-mêmes créant des effets de pression sur une paire de cylindres de travail destinés à laminer deux faces d'un produit métallique défilant horizontalement lorsque, de manière interne aux bâtis, les ensembles de cylindres supérieurs et inférieurs sont amenés en position serrée de laminage par des premiers moyens de déplacement respectivement à composante rectiligne principalement verticale voire inclinée par rapport à la verticale.The invention thus proposes a solution from a multi-roll mill stand comprising in a vertical direction an upper frame portion and a lower frame portion integral in one-piece form, each of the frame parts respectively comprising a set of rolls. upper and lower, said upper and lower rolls being composed of rows of support rollers for creating pressure effects on intermediate rolls, themselves creating pressure effects on a pair of work rolls for rolling two faces of a metal product scrolling horizontally when, internally to the frames, the upper and lower roller assemblies are brought to the tight rolling position by first displacement means respectively rectilinear component mainly vertical or even inclined relative to the vertical.
La cage de laminoir selon l'invention se caractérise enfin en ce qu' au moins une des rangées de galets d'appui (telles que les rangées A, D, E, H de la
La dite cage selon l'invention est aussi décrite au travers des caractéristiques de la revendication 1.Said cage according to the invention is also described through the features of claim 1.
En raison de l'introduction d'une nouvelle composante de déplacement d'au moins une des rangées de galets d'appui, il est ainsi possible d'ouvrir l'espace interne entre cylindres de travail de la cage sous une plus importante course pour par exemple venir insérer des cylindres de travail de diamètre plus important après avoir retiré un jeu initial de cylindres de plus faible diamètre, mais aussi de pouvoir resserrer des cylindres de travail de plus faible diamètre après avoir retiré un jeu initial de cylindres de plus fort diamètre. Il est ainsi avantageusement possible de pouvoir augmenter la gamme et la combinaison de cylindres de travail pour une même cage de type monobloc.Due to the introduction of a new displacement component of at least one of the rows of support rollers, it is thus possible to open the internal space between cylinders of work of the cage under a larger race for example to come to insert larger diameter work rolls after removing an initial set of smaller diameter cylinders, but also to be able to tighten working cylinders of smaller diameter after have removed an initial set of cylinders of larger diameter. It is thus advantageously possible to be able to increase the range and the combination of working rolls for the same one-piece type cage.
Un ensemble de sous-revendications présente également des avantages de l'invention liés à des modes préférés de réalisation de la cage.A set of subclaims also has advantages of the invention related to preferred embodiments of the cage.
Des exemples de réalisation et d'application sont fournis à l'aide de figures décrites :
- Figure 3
- premier mode de réalisation de la cage selon l'invention,
- Figure 4
- second mode de réalisation de la cage selon l'invention.
- Figure 3
- first embodiment of the cage according to the invention,
- Figure 4
- second embodiment of the cage according to the invention.
La cage selon l'invention prévoit qu'au moins une des rangées de galets d'appui (A, D, E, H) est couplée à un second moyen de déplacement (F1, EIM1, F2, EIM2) générant une composante principale de déplacement de la rangée de galets suivant au moins un axe horizontal en direction des cylindres de travail complémentairement au premier moyen de déplacement (vertical/incliné), le dit second moyen de déplacement étant activé dès que l'ensemble de cylindres inférieurs ou supérieurs auquel appartient la dite rangée de galets d'appui est amenée verticalement vers la position serrée de laminage.
The cage according to the invention provides that at least one of the rows of support rollers (A, D, E, H) is coupled to a second displacement means (F1, EIM1, F2, EIM2) generating a main component of moving the row of rollers along at least one horizontal axis in the direction of the working rolls in addition to the first moving means (vertical / inclined), the said second moving means being activated as soon as the set of lower or upper rolls to which belongs said row of support rollers is brought vertically to the tight rolling position.
Additionnellement et toujours dans le but d'augmenter les courses de déplacement interne des cylindres dans la cage, le second moyen de déplacement peut aussi assurer un déplacement (horizontal) complémentaire d'au moins une des rangées de galets d'appui (A, D, H, E) suivant un axe vertical.Additionally and always with the aim of increasing the internal displacement strokes of the rolls in the cage, the second moving means can also ensure a complementary (horizontal) displacement of at least one of the rows of support rollers (A, D , H, E) along a vertical axis.
Au moins une des rangées de galets d'appui (et idéalement deux ou quatre rangées pour un maximum d'augmentation de courses de déplacement, ici les rangées supérieures A, D et inférieures E, H horizontalement les plus éloignées) est ainsi ou sont respectivement couplée(s) à un élément de maintien intermédiaire (EIM1, EIM2) assurant un positionnement de ladite rangée de galets selon principalement les composantes verticale (ou incliné) et horizontale. Idéalement, les éléments de maintien intermédiaire présentent une forme de points d'appuis en « L » sous une section de rangée de galet d'appui de sorte qu'une face de la branche verticale du « L » est inclinée par rapport à la verticale. Préférentiellement car au plus simple de la réalisation, le dit élément de maintien intermédiaire comprenant donc une face externe inclinée par rapport à la verticale et disposée (mobile/glissante) en vis-à-vis d'une face interne (F1, F2) d'un des bâtis (B1, B2). Grâce à ces éléments de maintien intermédiaire, dès que le premier moyen de déplacement (vertical ou incliné) est activé, l'élément de maintien intermédiaire monte ou descend et par glissement et déplacement combiné horizontal/vertical relâche ou serre les cylindres entre eux indépendamment de l'action des autres dits premiers moyens de déplacement (vertical ou incliné) de cylindres de la cage tel que P1 et/ou P1'. Afin de permettre une telle réalisation simple de serrage/desserrage des cylindres, il est prévu que la face interne du bâti est parallèle à la face externe inclinée de l'élément de maintien intermédiaire (EIM1, EIM2), afin que par simple activation du premier moyen de déplacement (vertical tel que P1 et/ou P2) sur l'élément de maintien intermédiaire, ce dernier subisse aussi une poussée ou un retrait selon un déplacement horizontal par contact/glissement entre des couples de faces externe/interne du dit élément maintien intermédiaire et du bâti en contact.At least one of the rows of support rollers (and ideally two or four rows for a maximum increase of travel distances, here the upper rows A, D and lower E, H horizontally the furthest) is thus or respectively coupled to an intermediate holding member (EIM1, EIM2) providing a positioning of said row of rollers mainly in the vertical (or inclined) and horizontal components. Ideally, the intermediate support elements have a shape of 'L' bearing points under a bearing roll row section so that one face of the vertical leg of the 'L' is inclined to the vertical. Preferably because at the simplest of the embodiment, the said intermediate holding element thus comprising an external face inclined relative to the vertical and arranged (movable / sliding) vis-à-vis an inner face (F1, F2) d one of the frames (B1, B2). Thanks to these intermediate holding elements, as soon as the first moving means (vertical or inclined) is activated, the intermediate holding element ascends or descends and sliding and combined horizontal / vertical movement releases or tightens the cylinders between them independently of the action of the other so-called first means of displacement (vertical or inclined) of rolls of the cage such as P1 and / or P1 '. In order to allow such a simple embodiment of clamping / loosening of the rolls, it is provided that the inner face of the frame is parallel to the inclined outer face of the intermediate holding element (EIM1, EIM2), so that by simply activating the first displacement means (vertical such as P1 and / or P2) on the intermediate holding element, the latter also undergoes a thrust or withdrawal in a horizontal displacement by contact / sliding between pairs of external / internal faces of said holding element intermediate and the frame in contact.
Dans la pratique, le troisième moyen de déplacement (P2') est simplement constitué d'au moins une unité actionnée par un vérin, came ou autre actionneur. En
Sous une forme plus étendue, un tel troisième moyen de déplacement (P2') est installé au moins une ou idéalement deux voire quatre rangés de galets d'appuis les plus éloignés horizontalement des cylindres de travail (E, H) ou (A, D) ou (E, H, A, D. Il permet ainsi depuis le haut et le bas de bâti un contrôle simple du second moyen de déplacement horizontal des rangées de galets d'appui.In a more extensive form, such third displacement means (P2 ') is installed at least one or ideally two or four rows of support rollers farthest horizontally working rolls (E, H) or (A, D ) or (E, H, A, D. It thus allows from the top and the bottom of the frame a simple control of the second means of horizontal displacement of the rows of support rollers.
Enfin, le dit troisième moyen de déplacement (P2') peut avantageusement déplacer chacun des galets d'une rangée de galets d'appui selon une position prédéterminée permettant de corriger tout ou partie de déflexions (déformée) de profil des cylindres de travail et/ou des parties de bâti de cages (B1, B2) soumis aux effort de laminage.Finally, said third displacement means (P2 ') can advantageously move each of the rollers of a row of support rollers in a predetermined position to correct all or part of (deformed) profile deflections of the work rolls and / or or cage frame parts (B1, B2) subjected to the rolling forces.
