Description

La présente invention porte sur un dispositif de refroi­dissement d'un produit métallique en mouvement. Elle s'ap­plique en particulier aux produits plats de grande lar­geur, c'est-à-dire dont la largeur atteint par exemple au moins 2 m, notamment des tôles fortes.The present invention relates to a device for cooling a moving metal product. It applies in particular to flat products of large width, that is to say whose width reaches for example at least 2 m, in particular heavy plates.

On connaît déjà, notamment par le brevet belge no 900.784, un dispositif pour refroidir un produit métallique en mou­vement, qui comporte deux caissons transversaux perforés, disposés de part et d'autre de celui-ci et qui distribu­ent l'agent réfrigérant de manière uniforme selon la lar­geur du produit à refroidir.Already known, in particular by Belgian Patent No. 900 784, a device for cooling a metal product in motion, which comprises two perforated transverse boxes, arranged either side thereof and distributing the coolant so uniform according to the width of the product to be cooled.

On a cependant constaté que, dans certains cas, il était nécessaire de pouvoir faire varier le débit d'eau suivant la largeur du produit, en particulier dans le cas des tô­les de grande largeur.However, it has been found that, in certain cases, it was necessary to be able to vary the water flow rate according to the width of the product, in particular in the case of very wide sheets.

Cela est nécesaire en particulier lorsque les rives sont plus froides que la partie centrale de la tôle, avant d'­entrer dans l'installation de refroidissement; il est alors indispensable de réduire le débit appliqué sur les rives si l'on veut obtenir une distribution de tempéra­ture uniforme dans le produit refroidi.This is necessary in particular when the edges are cooler than the central part of the sheet, before entering the cooling installation; it is therefore essential to reduce the flow rate applied to the banks if a uniform temperature distribution is to be obtained in the cooled product.

La présente invention a précisément pour objet un dispo­sitif permettant d'adapter le refroidissement du produit de façon appropriée pour éviter l'apparition de rives froides après refroidissement.The present invention specifically relates to a device for adapting the cooling of the product appropriately to avoid the appearance of cold strands after cooling.

A cet effet, le dispositif de refroidissement qui fait l'­objet de la présente invention, qui comporte un caisson transversal supérieur et un caisson transversal inférieur par rapport au produit à refroidir, lesdits caissons étant pourvus d'orifices de passage de l'agent réfrigérant vers ledit produit, est essentiellement caractérisé en ce qu'au moins le caisson supérieur est divisé en au moins trois compartiments juxtaposés, un premier compartiment dit com­partiment central correspondant à la zone centrale du pro­duit et deux compartiments dits compartiments latéraux, correspondant respectivement aux deux zones de rive du produit, en ce que ladite division en compartiments est réalisée par des cloisons sensiblement perpendiculaires au fond dudit caisson supérieur et en ce que lesdites cloisons sont disposées de façon à former, à l'intérieur dudit caisson supérieur, un canal convergent dans le sens du déplacement dudit produit.To this end, the cooling device which is the subject of the present invention, which comprises an upper transverse box and a lower transverse box relative to the product to be cooled, said boxes being provided with orifices for passage of the coolant. towards said product, is essentially characterized in that at least the upper box is divided into at least three juxtaposed compartments, a first compartment called the central compartment corresponding to the central zone of the product and two compartments called lateral compartments, corresponding respectively to the two zones edge of the product, in that said division into compartments is carried out by partitions substantially perpendicular to the bottom of said upper box and in that said partitions are arranged so as to form, inside said upper box, a converging channel in the direction of movement of said product.

Selon l'invention, les orifices de passage de l'agent ré­frigérant ménagés dans ledit caisson supérieur sont munis d'embouts tubulaires disposés à l'intérieur dudit caisson et présentant une longueur plus faible que la hauteur in­térieure dudit caisson supérieur. L'ensemble de ces ori­fices est divisé en au moins trois groupes d'orifices par lesdites cloisons.According to the invention, the refrigerant passage openings formed in said upper box are provided with tubular end pieces arranged inside said box and having a shorter length than the internal height of said upper box. All of these orifices are divided into at least three groups of orifices by said partitions.

Egalement suivant l'invention, ledit canal convergent pré­sente un angle d'ouverture compris entre 40° et 150°; le canal convergent est de préférence disposé symétriquement par rapport à l'axe longitudinal du produit à refroidir.Also according to the invention, said converging channel has an opening angle of between 40 ° and 150 °; the converging channel is preferably arranged symmetrically with respect to the longitudinal axis of the product to be cooled.

Toujours selon l'invention, chacun desdits compartiments est équipé de moyens d'alimentation en agent réfrigérant, des moyens de réglage étant en outre prévus pour faire va­rier, de préférence séparément, le débit d'alimentation de chacun desdits compartiments en agent réfrigérant.Still according to the invention, each of said compartments is equipped with means for supplying refrigerant, adjustment means being further provided for varying, preferably separately, the feed rate of each of said compartments for refrigerant.

La présente invention va maintenant être décrite en détail en faisant référence à une forme préférée de réalisation illustrée à titre d'exemple dans la figure annexée qui montre
en (a) une vue en plan du dispositif de l'invention et
en (b) une vue latérale en coupe suivant la ligne brisée A-A de la vue (a).The present invention will now be described in detail with reference to a preferred embodiment illustrated by way of example in the appended figure which shows
in (a) a plan view of the device of the invention and
in (b) a side view in section along the broken line AA of view (a).

Dans cette figure, on a représenté en 1 une tôle forte se déplaçant suivant la flèche 2 sur un train de rouleaux 3, à la sortie d'un laminoir à chaud. Cette tôle 1 traverse un dispositif de refroidissement désigné globalement par le repère 4 et comprenant essentiellement un caisson su­périeur 5 et un caisson inférieur alimentés en agent ré­frigérant et disposés conformément à la technique anté­ rieure précitée. Pour ne pas compliquer inutilement le dessin, seul le caisson supérieur 5 est représenté dans la figure, car le caisson inférieur est soit inchangé par rapport à la technique antérieure précitée soit identique au caisson supérieur 5.In this figure, there is shown at 1 a heavy plate moving along arrow 2 on a train of rollers 3, at the outlet of a hot rolling mill. This sheet 1 passes through a cooling device generally designated by the reference 4 and essentially comprising an upper box 5 and a lower box supplied with refrigerant and arranged in accordance with the prior art above mentioned. In order not to unnecessarily complicate the drawing, only the upper box 5 is shown in the figure, because the lower box is either unchanged compared to the aforementioned prior art or identical to the upper box 5.

Comme on le voit bien dans la vue (a), le caisson 5 est divisé en trois compartiments 6, 7, 8 au moyen de deux cloisons verticales 9, 10 formant un canal convergent dans le sens du déplacement de la tôle. De façon connue en soi, la paroi inférieure du caisson, c'est-à-dire celle qui fait face à la tôle à refroidir, est percée d'orifices qui sont munis d'embouts tubulaires s'étendant à l'intérieur du caisson 5. A titre d'illustration, deux de ces orifi­ces 11 avec leurs embouts tubulaires 12, disposés respec­tivement dans les compartiments 6 et 7, sont représentés dans les vues (a) et (b). Il faut comprendre que de tels orifices sont répartis de manière appropriée sur le fond du caisson 5.As can be seen in view (a), the box 5 is divided into three compartments 6, 7, 8 by means of two vertical partitions 9, 10 forming a converging channel in the direction of movement of the sheet. In a manner known per se, the bottom wall of the box, that is to say the one which faces the sheet to be cooled, is pierced with orifices which are provided with tubular end pieces extending inside the box. 5. By way of illustration, two of these orifices 11 with their tubular ends 12, arranged respectively in the compartments 6 and 7, are shown in views (a) and (b). It should be understood that such orifices are distributed in an appropriate manner on the bottom of the box 5.

Les trois compartiments 6, 7, 8 sont juxtaposés, mais il n'y a aucune communication entr'eux. Ils sont alimentés séparément, selon des circuits d'écoulement de l'agent ré­frigérant schématisés dans la vue (b). La conduite prin­cipale d'alimentation 13 communique directement par un conduit central 14, avec une ouverture 15 ménagée dans la paroi postérieure du compartiment central 7. Cette ouver­ture est située de préférence sous le niveau de l'orifice d'entrée des embouts tubulaires 12 équipant ce comparti­ment 7. La section du conduit d'alimentation 14 du com­partiment central 7 a été ombrée dans la vue (a), pour clarifier l'illustration.The three compartments 6, 7, 8 are juxtaposed, but there is no communication between them. They are supplied separately, according to the refrigerant flow circuits shown diagrammatically in view (b). The main supply pipe 13 communicates directly through a central pipe 14, with an opening 15 formed in the rear wall of the central compartment 7. This opening is preferably located below the level of the inlet orifice of the tubular ends 12 fitted this compartment 7. The section of the supply duct 14 of the central compartment 7 has been shaded in view (a), to clarify the illustration.

De cette conduite principale 13 part une dérivation 17 en direction d'une conduite secondaire 18 qui communique avec les compartiments latéraux 6 et 8 par des conduits 19 et des ouvertures 20 ménagées dans la paroi antérieure du caisson 5. La section de passage des conduits d'ali­mentation 19 est également ombrée dans la vue (a). La con­duite de dérivation 17 est pourvue d'une vanne 22 permet­tant de régler le débit d'agent réfrigérant fourni aux compartiments 6 et 8.From this main pipe 13 there is a branch 17 in the direction of a secondary pipe 18 which communicates with the lateral compartments 6 and 8 by conduits 19 and openings 20 made in the front wall of the box 5. The passage section of the conduits d power 19 is also shaded in view (a). The bypass line 17 is provided with a valve 22 making it possible to adjust the flow of refrigerant supplied to the compartments 6 and 8.

La figure illustre un montage dans lequel les deux com­partiments 6 et 8 sont alimentés simultanément à partir d'une source commune. Il va de soi que cette représenta­tion n'est nullement limitative et que les compartiments latéraux 6 et 8 pourraient être alimentés indépendamment l'un de l'autre, à partir d'une source commune ou de sour­ces distinctes, et de façon symétrique ou asymétrique, sans pour autant sortir du cadre de la présente invention.The figure illustrates an arrangement in which the two compartments 6 and 8 are supplied simultaneously from a common source. It goes without saying that this representation is in no way limiting and that the lateral compartments 6 and 8 could be supplied independently of one another, from a common source or from separate sources, and in a symmetrical or asymmetrical manner. , without departing from the scope of the present invention.

Le dispositif de l'invention fonctionne de la façon sui­vante.The device of the invention operates as follows.

L'agent réfrigérant, qui est généralement de l'eau avec d'éventuels additifs appropriés, est fourni par la con­duite principale 13. A partir de celle-ci, une première portion de cet agent gagne le compartiment central 7 en traversant successivement le conduit 14 et l'ouverture 15. L'agent réfrigérant s'écoule alors par les embouts tubulaires 12 du compartiment central, pour venir couvrir la partie centrale de la surface supérieure du produit 1 à refroidir. La trajectoire de la première portion de l'­agent réfrigérant est schématisée par la flèche 16.The refrigerant, which is generally water with any appropriate additives, is supplied by the main pipe 13. From this, a first portion of this agent reaches the central compartment 7 by successively crossing the pipe 14 and the opening 15. The refrigerant then flows through the tubular ends 12 of the central compartment, to cover the central part of the upper surface of the product 1 to be cooled. The trajectory of the first portion of the refrigerant is shown diagrammatically by arrow 16.

Simultanément, une autre portion de l'agent réfrigérant est dirigée par la conduite de dérivation 17 vers la con­duite secondaire 18 qui alimente les deux compartiments latéraux 6 et 8 par les conduits 19 et les ouvertures 20. Par les embouts tubulaires 12 de ces compartiments laté­raux, l'agent réfrigérant s'écoule ensuite sur les zones latérales ou rives du produit 1 à refroidir. La trajec­toire de cette portion de l'agent réfrigérant est sché­matisée par la flèche 21.Simultaneously, another portion of the refrigerant is directed by the bypass line 17 to the secondary line 18 which supplies the two lateral compartments 6 and 8 by the conduits 19 and the openings 20. By the tubular ends 12 of these lateral compartments , the refrigerant then flows over the lateral zones or edges of the product 1 to be cooled. The trajectory of this portion of the refrigerant is shown diagrammatically by the arrow 21.

Grâce à cette subdivision du caisson en compartiments ré­partis sur la largeur du produit à refroidir, le disposi­tif de l'invention permet de moduler le débit dudit agent réfrigérant sur les différentes zones de la surface du produit à refroidir, afin d'assurer un refroidissement modulé du produit en évitant un refroidissement excessif des rives.Thanks to this subdivision of the box into compartments distributed over the width of the product to be cooled, the device of the invention makes it possible to modulate the flow rate of said refrigerant on the different zones of the surface of the product to be cooled, in order to ensure modulated cooling. of the product avoiding excessive cooling of the edges.

Il est notamment possible de réduire le débit d'agent ré­frigérant dans les compartiments latéraux, afin de com­penser l'effet de refroidissement dû au ruissellement de l'agent réfrigérant provenant du compartiment central.It is in particular possible to reduce the flow of refrigerant in the lateral compartments, in order to compensate for the cooling effect due to the runoff of the refrigerant from the central compartment.

A cet effet, l'inclinaison des cloisons 9, 10 par rapport au sens de déplacement du produit est choisie en fonction de la répartition des orifices 11 dans le fond du caisson 5, ainsi que des profils de débit désirés sur la largeur du caisson 5, perpendiculairement à la direction 2 du dé­placement du produit à refroidir. Dans les conditions usuelles, cette inclinaison est avantageusement comprise entre 20° et 75°.To this end, the inclination of the partitions 9, 10 relative to the direction of movement of the product is chosen according to the distribution of the orifices 11 in the bottom of the box 5, as well as the desired flow profiles over the width of the box 5 , perpendicular to direction 2 of the movement of the product to be cooled. Under the usual conditions, this inclination is advantageously between 20 ° and 75 °.
