Description

Dispositif de refroidissement à très haute puissance spécifique d'une bande métallique en mouvement.Very high power cooling device specific to a moving metal strip.
Domaine technique. La présente invention a trait à un dispositif pour le refroidissement à très haute puissance spécifique d'une bande métallique en mouvement dans un plan horizontal, en particulier d'une bande mince se déplaçant à grande vitesse sur un train de rouleaux. Un tel dispositif est en principe installé à la sortie d'un train de laminage à chaud. Son utilisation n'est cependant pas limitée à cette seule application.Technical area. The present invention relates to a device for cooling at very high specific power a metal strip moving in a horizontal plane, in particular a thin strip moving at high speed on a train of rollers. Such a device is in principle installed at the outlet of a hot rolling train. However, its use is not limited to this single application.
Etat de la techniqueState of the art
On connaît déjà diverses techniques de refroidissement des produits issus de laminoirs à bandes et ceux-ci impliquent généralement l'utilisation de rampes de refroidissement supérieures et inférieures disposées le long du trajet parcouru par la bande à refroidir. Ces rampes sont destinées à un refroidissement uniforme et homogène de celle-ci. Des chasses d'eau d'extrémité, comportant des gicleurs qui produisent des jets d'eau sous pression, empêchent l'eau de refroidissement de s'écouler longitudinalement hors du dispositif.Various techniques for cooling products from strip mills are already known and these generally involve the use of upper and lower cooling ramps arranged along the path traveled by the strip to be cooled. These ramps are intended for uniform and homogeneous cooling thereof. End flushers, having jets that produce pressurized water jets, prevent cooling water from flowing longitudinally out of the device.
Actuellement, on constate le développement de techniques de refroidissement dites à très haute puissance spécifique qui semblent promises à un bel avenir de par la qualité améliorée des produits obtenus.Currently, there is the development of so-called very high specific power cooling techniques which seem to promise a bright future due to the improved quality of the products obtained.
L'application d'un refroidissement à très haute puissance spécifique implique l'utilisation de débits spécifiques d'eau de refroidissement très élevés, dépassant fréquemment 20 l/s.m2 et pouvant atteindre 70 l/s.m2 ou davantage. On constate dans ces conditions opératoires qu'il y a formation d'un matelas d'eau sur le produit à refroidir avec pour conséquence que ledit produit en mouvement subit l'action d'une force de freinage importante.The application of very high specific power cooling involves the use of very high specific cooling water flows, frequently exceeding 20 l / sm 2 and up to 70 l / sm 2 or more. It is found in these operating conditions that there is formation of a water mattress on the product to be cooled with the consequence that said moving product undergoes the action of a significant braking force.
Dans le cas de bandes moyennes ou épaisses laminées à chaud au TLB ou train à larges bandes, le freinage dû à la présence du matelas d'eau est compensé par la traction exercée sur la bande par les rouleaux de la table de sortie car lesdits rouleaux sont en survitesse par rapport à la bande et l'effort de frottement exercé sur la bande est suffisamment élevé pour assurer l'effort de traction précité. L'enclenchement de l'eau de refroidissement peut donc être opéré avant même que la tête de la bande n'entre dans le dispositif de refroidissement et permettre de la sorte le traitement uniforme de la totalité de ladite bande.In the case of medium or thick strips hot rolled with TLB or wide strip train, the braking due to the presence of the water mattress is compensated by the traction exerted on the strip by the rollers of the output table because said rollers are overspeed relative to the strip and the friction force exerted on the strip is sufficiently high to ensure the aforementioned tensile force. The engagement of the cooling water can therefore be operated even before the head of the strip enters the cooling device and thus allow uniform treatment of the entire said strip.
Par contre, dans le cas des bandes minces, l'effort de frottement exercé sur la bande est nettement plus faible et l'effort de traction opéré par le banc de rouleaux n'est plus assez grand pour compenser le freinage dû à la présence du matelas d'eau. Il en résulte que l'eau de refroidissement ne peut donc être enclenchée que quand la tête de ladite bande a traversé la section de refroidissement et exerce une traction sur le reste de la bande.On the other hand, in the case of thin strips, the friction force exerted on the strip is much lower and the tensile force operated by the bank of rollers is no longer large enough to compensate for the braking due to the presence of the water mattress. As a result, the cooling water can therefore only be engaged when the head of said strip has passed through the cooling section and exerts traction on the rest of the strip.
Pour les produits les plus minces, il faut même attendre que la tête de la bande soit engagée dans la bobineuse qui assure alors une traction suffisante pour compenser le freinage dû au matelas d'eau. Cette manière de procéder a pour effet que la tête du produit, sur une longueur au moins égale à la distance entre la dernière cage et la bobineuse (c'est-à-dire fréquemment plus de 1 00 m), ne subit pas le refroidissement requis et est perdue car non conforme au produit visé.For the thinnest products, it is even necessary to wait until the head of the strip is engaged in the winder which then provides sufficient traction to compensate for the braking due to the water mattress. This way of proceeding has the effect that the product head, over a length at least equal to the distance between the last stand and the winder (that is to say frequently more than 1 00 m), does not undergo cooling required and is lost because it does not comply with the targeted product.
Présentation de l'inventionPresentation of the invention
La présente invention a pour objet de proposer un dispositif de refroidissement du type mentionné dans l'introduction, qui permet, par des moyens simples, d'éviter la perte des têtes de bandes minces en assurant la régularité du refroidissement à très haute puissance spécifique d'une bande métallique mince en mouvement.The object of the present invention is to propose a cooling device of the type mentioned in the introduction, which makes it possible, by simple means, to avoid the loss of the heads of thin strips by ensuring the regularity of cooling at very high specific power d 'a thin metal band in motion.
Conformément à la présente invention, un dispositif pour le refroidissement à très haute puissance spécifique d'une bande métallique mince en mouvement dans un plan horizontal, qui comporte des rampes de refroidissement supérieures disposées le long du trajet parcouru par ladite bande, ainsi que des moyens de retenue de l'eau disposés respectivement à l'entrée et à la sortie du dispositif de refroidissement, avec éventuellement des chasses d'eau supplémentaires situées entre les moyens de retenue de l'eau précités, est caractérisé en ce qu'il comporte au moins une paire de rouleaux pinceurs disposés sur le trajet de la bande après son entrée dans la section de refroidissement. Les rouleaux pinceurs forment un dispositif composé de cylindres placés face à face entre lesquels la bande passe et qui sont refermés immédiatement après le passage de la tête de la bande de manière à exercer un effort de traction sur ladite bande. La traction exercée par les rouleaux pinceurs étant supérieure à l'effort de freinage dû au matelas d'eau, l'eau de refroidissement peut donc être enclenchée dès que ces rouleaux pinceurs ont prise sur la tête de ladite bande.According to the present invention, a device for cooling at very high specific power a thin metal strip moving in a horizontal plane, which includes upper cooling ramps arranged along the path traveled by said strip, as well as means retaining means disposed respectively at the inlet and at the outlet of the cooling device, with optionally additional flushes located between the aforementioned water retaining means, is characterized in that it comprises at minus a pair of pinch rollers arranged in the path of the strip after it has entered the cooling section. The pinch rollers form a device composed of cylinders placed face to face between which the strip passes and which are closed immediately after the passage of the head of the strip so as to exert a tensile force on said strip. The traction exerted by the pinch rollers being greater than the braking force due to the water mattress, the cooling water can therefore be engaged as soon as these pinch rollers have taken hold on the head of said strip.
Il s'en suit que la longueur de la bande non refroidie et hors tolérances est réduite à la distance entre la dernière cage de laminage et les rouleaux pinceurs, c'est-à-dire environ 20 m contre plus de 100 m en l'absence de rouleaux pinceurs. En outre, la présence de rouleaux pinceurs présente l'avantage de constituer un barrage pour l'eau de refroidissement accumulée sur la face supérieure de la bande et ainsi de coopérer avec des dispositifs tels que des chasses d'arrêt d'eau montées à la sortie de la section de refroidissement pour empêcher que l'eau ne suive le produit.It follows that the length of the uncooled strip and out of tolerance is reduced to the distance between the last rolling stand and the pinch rollers, that is to say approximately 20 m against more than 100 m in no pinch rollers. In addition, the presence of pinch rollers has the advantage of constituting a barrier for the cooling water accumulated on the upper face of the strip and thus of cooperating with devices such as flushing flushes mounted at the exit from the cooling section to prevent water from following the product.
Suivant une forme de réalisation particulière, au moins une paire de rouleaux pinceurs est disposée sur le trajet de la bande après sa sortie hors du dispositif de refroidissement.According to a particular embodiment, at least one pair of pinch rollers is arranged in the path of the strip after it leaves the cooling device.
Suivant une forme de réalisation préférée, il est prévu d'installer au moins une paire de rouleaux pinceurs additionnels à l'intérieur du dispositif de refroidissement, de préférence sensiblement à mi-distance entre la dernière cage de laminage et la première paire de rouleaux pinceurs rencontrés par la bande dans sa progression.According to a preferred embodiment, provision is made to install at least one pair of additional pinch rollers inside the cooling device, preferably substantially halfway between the last rolling stand and the first pair of pinch rollers. encountered by the band in its progression.
