Description

La présente invention concerne un dispositif d'accumulation de bande laminée de métal ferro- magnétique, notamment de bande de métal laminée à chaud, à froid, revêtue ou non revêtue. Par dispositif d'accumulation, on entend un dispositif qui joue un rôle de "réservoir-tampon", par exemple entre les cages de laminoir et les installations de traitement ultérieur de la bande laminée.The present invention relates to a device for accumulating a rolled strip of ferromagnetic metal, in particular a hot-rolled, cold-rolled, coated or uncoated metal strip. By accumulation device is meant a device which acts as a "buffer tank", for example between the rolling mill stands and the installations for further processing the rolled strip.

On connaît deux types d'accumulateur de bandes laminée, un premier type d'accumulateur comportant des boucles horizontales et un deuxième type d'accumulateur comportant des boucles verticales.En général, le dispositif d'accumulation consiste en un ou plusieurs cylindres mobiles dits de renvoi sur lesquels passe la bande laminée 81 l'enveloppant d'un angle d'environ 180°.La bande laminée est généralement supportée par des rouleaux parallèles dont les axes de rotation sont perpendiculaires à la direction du mouvement de la bande. Dans le cas de dispositifs d'accumulation verticaux, la bande laminée passe entre des rouleaux opposés qui empêchent le battement de celle-ci sur lesdits rouleaux ; ce qui endommagerait l'état de surface desdites bandes. Un inconvénient notoire des dispositifs d'accumulation connus consiste en ce que la tension exercée sur la bande est élevée et que, pour la limiter, il faut prévoir des dispositifs de soutien, c'est-à-dire des rouleaux de support nombreux.C'est dans le cas-de grandes longueurs accumulées que les rouleaux supports doivent être escamotables pour qu'on puisse évacuer la bande du dispositif d'accumulation.There are two types of accumulator of laminated strips, a first type of accumulator comprising horizontal loops and a second type of accumulator comprising vertical loops. In general, the accumulation device consists of one or more movable cylinders called return on which the laminated strip 81 passes enveloping it by an angle of about 180 °. The laminated strip is generally supported by parallel rollers whose axes of rotation are perpendicular to the direction of movement of the strip. In the case of vertical storage devices, the laminated strip passes between opposite rollers which prevent the latter from flapping on said rollers; which would damage the surface condition of said strips. A notable drawback of known storage devices is that the tension exerted on the strip is high and that, to limit it, it is necessary to provide support devices, i.e. numerous support rollers. 'is in the case of long accumulated lengths that the support rollers must be retractable so that the strip can be removed from the accumulation device.

Dans le cas de dispositifs d'accumulation verticaux, la construction est encore plus compliquée étant donné qu'on se trouve en présence de rouleaux opposés qui maintiennent entre eux la bande laminée.In the case of vertical storage devices, construction is even more complicated since there are opposite rollers which hold the laminated strip between them.

On a ensuite cherché à fournir des dispositifs d'accumulation de bande laminée qui évitent les inconvénients cités. C'est ainsi que le document US-A-4 281 784 décrit un dispositif d'accumulation du type mentionné dans lequel la bande métallique est supportée par effet magnétique par le haut, grâce à un agencement de rouleaux non magnétiques et d'aimants fixes disposés entre ceux-ci. Le document US-A-2 967 007 décrit également un dispositif d'accumulation dans lequel la bande métallique est supportée par des rouleaux magnétiques constitués par des disques magnétiques séparés par des disques en un matériau isolant. Par ailleurs, le document US-A-2 750 187 décrit un dispositif d'accumulation de bande laminée d'un type particulier qui fait appel à des dispositifs magnétiques connus, c'est-à-dire les rouleaux décrits dans US-A-2 967 007 par exemple. Un grave inconvénient de ces rouleaux magnétiques consiste en ce qu'ils attirent également les particules métalliques qui "collent" à leur périphérie et qui s'incrustent dans la paroi cylindrique ou dans la tôle laminée. Ceci entraîne une usure prématurée du cylindre et un état de surface inacceptable de la bande laminée.We then sought to provide laminated strip accumulation devices which avoid the drawbacks mentioned. Thus document US-A-4 281 784 describes an accumulation device of the type mentioned in which the metal strip is supported by magnetic effect from above, thanks to an arrangement of non-magnetic rollers and fixed magnets arranged between them. Document US-A-2 967 007 also describes an accumulation device in which the metal strip is supported by magnetic rollers constituted by magnetic discs separated by discs made of an insulating material. Furthermore, document US-A-2,750,187 describes a device for accumulating laminated strip of a particular type which uses known magnetic devices, that is to say the rollers described in US-A- 2,967,007 for example. A serious disadvantage of these magnetic rollers is that they also attract metallic particles which "stick" to their periphery and which become embedded in the cylindrical wall or in the rolled sheet. This results in premature wear of the cylinder and an unacceptable surface condition of the laminated strip.

La présente invention vise à fournir un dispositif d'accumulation du type susmentionné destiné à l'accumulation de bande de métal laminée, notamment de métal ferro-magnétique, qui est de construction particulièrement simple.The present invention aims to provide an accumulation device of the aforementioned type intended for the accumulation of laminated metal strip, in particular ferro-magnetic metal, which is of particularly simple construction.

Un autre but de la présente invention vise à fournir un dispositif d'accumulation de bande de métal laminée, ladite bande étant supportée par effet magnétique, qui présente une conception et une construction différente de celles de l'état de la technique.Another object of the present invention is to provide a device for accumulating a laminated metal strip, said strip being supported by magnetic effect, which has a design and construction different from those of the prior art.

La présente invention vise finalement à fournir un dispositif d'accumulation de bande de métal laminée, dans lequel ladite bande est supportée par effet magnétique et qui ne présente pas les inconvénients des installations connues, tels que l'incrustation des particules métalliques dans le cylindre ou la bande de tôle.The present invention finally aims to provide a device for accumulating a laminated metal strip, in which said strip is supported by magnetic effect and which does not have the disadvantages known installations, such as the encrustation of metal particles in the cylinder or the sheet metal strip.

Selon la présente invention, le dispositif d'accumulation de bande laminée de métal ferro-magnétique comportant au moins un cylindre de renvoi et dans lequel ladite bande est suspendue par effet magnétique est caractérisé en ce que les rouleaux de suspension consistent chacun en un cylindre creux tournant autour de son axe et comportant, à l'intérieur, un ou plusieurs dispositifs de magnétisation fixes qui exercent un effort d'attraction suffisant sur la bande pour l'appliquer contre la paroi extérieure dudit rouleau.According to the present invention, the device for accumulating a laminated strip of ferro-magnetic metal comprising at least one return cylinder and in which said strip is suspended by magnetic effect is characterized in that the suspension rollers each consist of a hollow cylinder rotating around its axis and comprising, inside, one or more fixed magnetization devices which exert a sufficient attraction force on the strip to apply it against the external wall of said roller.

Les rouleaux de suspension sont donc avantageusement disposés à l'extérieur de la bouche formée par le cylindre de renvoi.The suspension rollers are therefore advantageously arranged outside the mouth formed by the return cylinder.

Avantageusement, le dispositif de magnétisation est constitué par des plaquettes de ferrite qui garantissent l'aimantation pendant une durée de vie prolongée. Les aimants fixes occupent, de préférence, un section de 45 à 135', tout particulièrement de 90 à 135' dans la section du rouleau.Advantageously, the magnetization device consists of ferrite plates which guarantee magnetization for an extended service life. The fixed magnets preferably occupy a section of 45 to 135 ', especially 90 to 135' in the section of the roll.

Selon une forme d'exécution préférée, le cylindre creux est constitué par une matière amagnétique ou paramagnétique.According to a preferred embodiment, the hollow cylinder consists of a non-magnetic or paramagnetic material.

On constate donc que de cette manière, la bande laminée à accumuler dans le dispositif de l'invention est suspendue par effet ferro-magnétique et l'évacuation de la bande hors du dispositif d'accumulation suivant l'invention est notablement facilitée.It is therefore found that in this way, the laminated strip to accumulate in the device of the invention is suspended by ferro-magnetic effect and the evacuation of the strip from the accumulation device according to the invention is significantly facilitated.

Par ailleurs, selon la présente invention, le déplacement du cylindre de renvoi sur lequel est partiellement enroulée la bande laminée peut être supérieur à la distance entre deux rouleaux de suspension, lorsque la bande laminée est engagée sur celui-ci, étant donné que son mouvement n'est plus gêné comme dans certains dispositifs classiques, par les cylindres intérieurs à la boucle.Furthermore, according to the present invention, the displacement of the deflection cylinder on which the laminated strip is partially wound can be greater than the distance between two suspension rollers, when the laminated strip is engaged thereon, since its movement is no longer hindered as in some conventional devices, by the cylinders inside the loop.

D'autre part, les particules de métal magnétisé et "collant" au rouleau de suspension peuvent être éliminées facilement, par raclage ou brossage par exemple, de la surface du rouleau ou de la bande, à l'extérieur de la zone magnétisée.On the other hand, the particles of magnetized and "sticky" metal on the suspension roller can be easily removed, by scraping or brushing for example, from the surface of the roller or of the strip, outside the magnetized zone.

D'autres détails et avantages de la présente invention apparaîtront à la lecture d'une forme d'exécution préférée représentée dans les dessins dans lesquels :

  • - la figure 1 représente une vue schématique partielle d'un dispositif d'accumulation de bande laminée selon l'invention; et
  • - la figure 2 représente une vue schématique en coupe d'un rouleau de suspension selon la présente invention.
Other details and advantages of the present invention will appear on reading a preferred embodiment represented in the drawings in which:
  • - Figure 1 shows a partial schematic view of a laminated strip accumulation device according to the invention; and
  • - Figure 2 shows a schematic sectional view of a suspension roller according to the present invention.

En référence aux figures, le dispositif d'accumulation de bande comporte un cylindre de renvoi 1 monté sur un chariot mobile 2 dont le mouvement peut être commandé par un moyen d'entraînement 3 connu en soi. La bande laminée de métal ferro-magnétique 5 provenant par exemple d'une cage de laminoir subit un renvoi d'angle de 180* autour du cylindre de renvoi 1 et est ensuite envoyée soit sur un autre cylindre de renvoi soit vers l'installation de traitement ultérieur. La figure représente un dispositif d'accumulation de bande laminée horizontal mais il est bien évident que la présente invention n'est pas limitée à ce type de dispositif d'accumulation et que celui-ci peut également être disposé verticalement.With reference to the figures, the tape accumulation device comprises a return cylinder 1 mounted on a mobile carriage 2, the movement of which can be controlled by a drive means 3 known per se. The rolled strip of ferromagnetic metal 5 for example from a roll stand angle undergoes a deflection 180 ° around the deflection roller 1 and is then sent either on another deflection roller or to install further processing. The figure shows a horizontal laminated strip accumulation device, but it is obvious that the present invention is not limited to this type of accumulation device and that this can also be arranged vertically.

Selon l'invention, la bande laminée 5 est suspendue par effet ferro-magnétique à des rouleaux de suspension 7 qui sont disposés à l'extérieur de la boucle formée par le cylindre de renvoi 1.According to the invention, the laminated strip 5 is suspended by ferro-magnetic effect from suspension rollers 7 which are arranged outside the loop formed by the return cylinder 1.

On constate aisément que la bande laminée 5 peut aisément être évacuée du dispositif d'accumulation sans que les rouleaux intérieurs ne gênent cette opération.It can easily be seen that the laminated strip 5 can easily be removed from the accumulation device without the inner rollers interfering with this operation.

Par ailleurs, le chariot 2 comportant le cylindre de renvoi 1 peut avantageusement être déplacé pendant que la bande laminée circule, sans que ce mouvement soit gêné par les cylindres intérieurs. En effet, dans les dispositifs d'accumulation connus, le chariot ne peut être déplacé que d'une distance égale à l'espace séparant deux rouleaux sans que le rouleau disposé en aval du cylindre ne doive être escamoté.Furthermore, the carriage 2 comprising the return cylinder 1 can advantageously be moved while the laminated strip is circulating, without this movement being hampered by the interior cylinders. In fact, in known accumulation devices, the carriage can only be moved a distance equal to the space separating two rollers without the roller disposed downstream of the cylinder having to be retracted.

Dans le cas d'un dispositif d'accumulation vertical, le dispositif selon la présente invention est notablement simplifié par rapport aux dispositifs connus, étant donné que des rouleaux disposés d'un côté de la bande suffisent pour empêcher les battements de celle-ci, alors que, dans les dispositifs connus, il fallait disposer des rouleaux des deux côtés de la bande.In the case of a vertical storage device, the device according to the present invention is considerably simplified compared to known devices, since rollers arranged on one side of the strip are sufficient to prevent the latter from flapping, whereas, in known devices, it was necessary to have rollers on both sides of the strip.

Selon la présente invention, le rouleau consiste en un cylindre creux 11 qui tourne autour de son axe et qui est supporté par celui-ci de manière connue en soi, par exemple par des roulements et/ou des bagues. Ledit cylindre creux comporte, à l'intérieur, un ou plusieurs dispositifs de magnétisation 12 qui exercent un effort d'attraction suffisant sur la bande pour appliquer celle-ci contre la paroi dudit cylindre.According to the present invention, the roller consists of a hollow cylinder 11 which rotates around its axis and which is supported by the latter in a manner known per se, for example by bearings and / or rings. Said hollow cylinder has, inside, one or more magnetization devices 12 which exert a sufficient attraction force on the strip to apply the latter against the wall of said cylinder.

Avantageusement, le cylindre creux est constitué par une matière amagnétique ou paramagnétique. De préférence, le dispositif de magnétisation consiste en plusieurs plaquettes de ferrite qui recouvrent un secteur allant de 90 à 135' dans la section du rouleau de suspension.Advantageously, the hollow cylinder is formed by a non-magnetic or paramagnetic material. Preferably, the magnetization device consists of several ferrite plates which cover a sector ranging from 90 to 135 'in the section of the suspension roller.

Il faut noter que la forme d'exécution décrite n'est donnée qu'à titre d'exemple et que d'autres formes d'exécution qui entrent dans le cadre de la revendication 1 font également partie de la présente invention.It should be noted that the embodiment described is given only by way of example and that other embodiments which fall within the scope of claim 1 also form part of the present invention.
