Description

L'invention concerne un dispositif de production d'un rideau de liquide, du type comportant une rampe d'arrivée du liquide et une buse de sortie du liquide.The invention relates to a device for producing a curtain of liquid, of the type comprising a liquid inlet ramp and a liquid outlet nozzle.

Un dispositif de ce type est connu par le document FR-A-2 580 199 au nom du demandeur et peut être doté de moyens de réglage de la largeur du rideau de liquide. De tels dispositifs sont notam­ment destinés au refroidissement par rideaux d'eau d'un produit métallurgique plat circulant transversalement aux rideaux, ceux-ci pouvant être produits soit par alimentation sous pression, soit par gravité.A device of this type is known from document FR-A-2 580 199 in the name of the applicant and can be provided with means for adjusting the width of the curtain of liquid. Such devices are in particular intended for cooling by water curtains of a flat metallurgical product circulating transversely to the curtains, the latter being able to be produced either by feeding under pressure or by gravity.

Toutefois, une des limitations à l'utilisation de rideaux d'eau sur les installations de refroidissement, par rapport aux techniques concurrentes, réside dans la difficulté à moduler le débit dans le sens de la largeur du produit. Les solutions les plus simples, qui consistent, par exemple, à faire varier localement l'épaisseur de la fente, atteignent vite leurs limites et les rende­ments sont très médiocres.However, one of the limitations to the use of water curtains on cooling installations, compared to competing techniques, lies in the difficulty of modulating the flow in the direction of the width of the product. The simplest solutions, which consist, for example, in locally varying the thickness of the slit, quickly reach their limits and the yields are very poor.

L'invention a pour but de proposer un système de produc­tion de rideau de liquide à débit variable sur la largeur du rideau.The object of the invention is to propose a system for producing a curtain of liquid with variable flow over the width of the curtain.

A cet effet, la buse de sortie du dispositif de l'inven­tion est constituée par des caissons juxtaposés reliés à la rampe d'arrivée de liquide au travers de moyens individuels de réglage du débit, les caissons comportant des fentes de sortie disposées successivement dans le prolongement l'une de l'autre et séparées par des espaces qui sont occupés par des coins de liaison dont la pointe est orientée dans le sens d'écoulement du liquide.To this end, the outlet nozzle of the device of the invention is constituted by juxtaposed boxes connected to the liquid arrival ramp through individual means for adjusting the flow rate, the boxes comprising outlet slots successively arranged in the extension of one another and separated by spaces which are occupied by connecting corners whose point is oriented in the direction of flow of the liquid.

Ces coins guident les bords voisins de deux rideaux élémen­taires contigus dès leur naissance et les réunissent de manière à ne produire qu'un rideau unique. Les coins permettent l'élargisse­ment des jets en s'opposant à leur retreint naturel, et évitent le bourrelet qui se forme généralement sur les bords des rideaux ou tout au moins en limitent l'importance. Ils sont réalisés en un matériau présentant une bonne mouillabilité vis-à-vis du liquide du rideau : par exemple en caoutchouc pour un rideau d'eau.These corners guide the neighboring edges of two contiguous elementary curtains from their birth and bring them together so as to produce only a single curtain. The corners allow the widening of the jets by opposing their natural constriction, and avoid the bead which generally forms on the edges of the curtains or at least limit their importance. They are made of a material having good wettability with respect to the curtain liquid: for example rubber for a water curtain.

Les moyens individuels de réglage du débit autorisent des variations importantes de débit sur la largeur du rideau, mais, de préférence, le rapport des débits linéaires entre deux cais­sons voisins est maintenu entre 1 et 4 pour ne pas risquer une désagrégation des rideaux élémentaires réunis grâce aux coins de liaison.The individual flow adjustment means allow significant variations in flow over the width of the curtain, but preferably, the ratio of linear flow rates between two neighboring caissons is maintained between 1 and 4 so as not to risk the disaggregation of the elementary curtains brought together by means of the connecting corners.

Le dispositif de l'invention permet : d'obtenir un profil de débit choisi sur la largeur du product à traiter avec des variations de forte amplitude ; de sélectionner la ou les zones du produit à refroidir ; d'adapter la largeur de l'installation à la largeur du produit et, par conséquent, de diminuer les quantités d'eau en circulation ; et de suppri­mer les systèmes externes de masques mis en place sur plu­sieurs installations de refroidissement existantes et destinés à ne pas refroidir les rives du produit.The device of the invention makes it possible: to obtain a flow profile chosen over the width of the product to be treated with variations of high amplitude; to select the zone or zones of the product to be cooled; to adapt the width of the installation to the width of the product and, consequently, to reduce the quantities of water in circulation; and to remove the external mask systems installed on several existing cooling installations and intended not to cool the edges of the product.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante d'un mode particulier de réalisation. Il sera fait référence aux dessins annexés sur lesquels:

  • - la figure 1 représente, en vue schématique de face, un dispositif de production de rideau de liquide conforme à l'invention ;
  • - la figure 2 est une représentation photographique d'un dispositif comportant deux caissons juxtaposés sans coin de liaison ;
  • - la figure 3 est une ature représentation photographi­que du même dispositif, le coin de liaison étant en place et les deux débits sensiblement égaux, et
  • - la figure 4 est une vue similaire, le débit à droite étant fortement supérieur à celui de gauche.
Other characteristics and advantages of the invention will emerge from the following description of a particular embodiment. Reference will be made to the appended drawings in which:
  • - Figure 1 shows, in schematic front view, a liquid curtain production device according to the invention;
  • - Figure 2 is a photographic representation of a device comprising two juxtaposed boxes without connecting corner;
  • FIG. 3 is an ature photographic representation of the same device, the connecting corner being in place and the two flow rates substantially equal, and
  • - Figure 4 is a similar view, the flow rate on the right being much higher than that on the left.

Le dispositif représenté à la figure 1 comporte une rampe collective d'arrivée d'eau 1 alimentée grâce à une pompe d'amont 2. Sur la rampe 1 sont piquées des conduites 3 d'alimentation de caissons individuels 4. Ces caissons 4 sont juxtaposés à la suite les uns des autres de manière que leurs fentes de sortie 5 ménagée dans le fond soient sensiblement alignées et constituent globalement la buse de production du rideau d'eau. Les conduites d'alimentation 3 renferment des moyens individuels 6 de réglage du débit, tels que des vannes. Ces moyens peuvent être réglés individuel­lement, ou à distance, par des commandes regroupées au sein d'une unité de commande. Les caissons comportent, en aval des conduites d'alimentation, une zone intermédiaire d'élar­gissement 7 qui conduit à la zone 8 de répartition. Cette zone 8 peut contenir un collimateur destiné à éliminer les turbulences de l'eau. De tels collimateurs sont connus par le document FR-A-2379779.The device represented in FIG. 1 comprises a collective ramp for the arrival of water 1 supplied by an upstream pump 2. On the ramp 1 are pipelines 3 supplying individual boxes 4. These boxes 4 are juxtaposed following each other so that their outlet slots 5 formed in the bottom are substantially aligned and generally constitute the production nozzle of the water curtain. Supply lines 3 contain individual means 6 for adjusting the flow rate, such as valves. These means can be adjusted individually, or remotely, by commands grouped within a control unit. The boxes have, downstream of the supply lines, an intermediate enlargement zone 7 which leads to the distribution zone 8. This zone 8 can contain a collimator intended to eliminate turbulence from the water. Such collimators are known from document FR-A-2379779.

En aval de cette zone 8, chaque rideau se fome entre deux plaques 20 qui déterminent la largeur des fentes de sortie 5. Deux plaquettes 21 d'extrémité insérées entre les plaques 20 déterminent la largeur du rideau à sa source.Downstream of this zone 8, each curtain is formed between two plates 20 which determine the width of the outlet slots 5. Two end plates 21 inserted between the plates 20 determine the width of the curtain at its source.

Entre les extrémités voisines de deux fentes conti­guës 5 subsiste donc un espace 9 résultant en particulier de l'épaisseur de ces plaquettes, 21.Between the adjacent ends of two contiguous slots 5 there therefore remains a space 9 resulting in particular from the thickness of these plates, 21.

Conformément à l'invention, cet espace 9 est occupé, en aval des fentes 5 par rapport au sens d'écoulement, par un coin 10 en caoutchouc placé pointe vers le bas, qui sert à guider et réunir des bords voisins 11 et 12 de deux rideaux produits par deux fentes 5 contiguës. Aux extrémités isolées des fentes 5 de bout de buse, on peut prévoir un demi-coin 13 écartant le bord isolé du rideau pour éviter un retreint naturel excessif. Les bords libres forment néanmoins un bourre­let 15.According to the invention, this space 9 is occupied, downstream of the slots 5 relative to the direction of flow, by a wedge 10 of rubber placed point downward, which serves to guide and join neighboring edges 11 and 12 of two curtains produced by two contiguous slots 5. At the isolated ends of the nozzle end slots 5, a half-wedge 13 can be provided which spreads the insulated edge of the curtain to avoid excessive natural shrinking. The free edges nevertheless form a bead 15.

L'ensemble des rideaux voisins est réuni très rapide­ment en aval des fentes en un rideau d'eau unique 14 s'éten­dant sur toute la largeur du produit à traiter 16, lequel défile (dans une direction perpendiculaire au plan de la figure) sur une table à rouleaux 17 placée à un peu plus d'un mètre sans les caissons.The set of neighboring curtains is brought together very quickly downstream of the slots in a single water curtain 14 extending over the entire width of the product to be treated 16, which scrolls (in a direction perpendicular to the plane of the figure) over a roller table 17 placed at a little over a meter without the boxes.

La hauteur préférée du rideau est de l'ordre de 1 m. Au delà, il peut y avoir des risques de désagrégation du rideau dans les sites de faible débit.The preferred height of the curtain is of the order of 1 m. Beyond this, there may be risks of the curtain falling apart in low-speed sites.

La largeur du rideau est, par exemple, d'environ 2,50 m et peut provenir de deux caissons juxtaposés ou plus.The width of the curtain is, for example, about 2.50 m and can come from two or more juxtaposed boxes.

Les variations admissibles de débit entre deux caissons juxtaposés sont de l'ordre de 1 à 4. Pour un rapport de débit supérieur apparaissent des risques de désagrégation.The admissible variations in flow between two juxtaposed boxes are of the order of 1 to 4. For a higher flow ratio, risks of disaggregation appear.

On notera que l'espace 9 peut aussi résulter de la variation d'écartement entre caissons, lorsque cela est rendu possible par une constitution de la tuyauterie d'alimentation autorisant le déplacement relatif des caissons (tuyauterie souple, ou soufflet, par exemple). Dans ce cas, l'écartement relatif des caissons peut être adapté de sorte que la largeur totale du rideau 14 corresponde à la largeur du produit. Il suffit alors de disposer entre deux fentes contiguës des coins de dimension adéquate, c'est à dire tels que leurs bords se trouvent sensiblement dans le prolongement des faces internes des plaquettes 21.It will be noted that the space 9 may also result from the variation in spacing between boxes, when this is made possible by a constitution of the supply piping allowing the relative movement of the boxes (flexible piping, or bellows, for example). In this case, the relative spacing of the boxes can be adapted so that the total width of the curtain 14 corresponds to the width of the product. It then suffices to have wedges of adequate size between two contiguous slots, that is to say such that their edges are substantially in line with the internal faces of the plates 21.

Les figures 2, 3 et 4 montrent clairement les avantages du coin entre deux fentes successives. La figure 2 représente les rideaux obtenus avec deux caissons adjacents sans coin. Ces rideaux sont nettement séparés.Figures 2, 3 and 4 clearly show the advantages of the corner between two successive slots. Figure 2 shows the curtains obtained with two adjacent boxes without corner. These curtains are clearly separated.

La figure 3 montre le même ensemble de caissons après que le coin ait été mis en place. Les débits sont sensiblement identiques dans les deux parties du rideau. On notera que la continuité entre les deux parties est parfaite, le bourre­let central étant pratiquement inexistant, alors que des bourrelets d'extrémités se forment simultanément au retreint naturel.Figure 3 shows the same set of boxes after the corner has been put in place. The flow rates are substantially identical in the two parts of the curtain. It will be noted that the continuity between the two parts is perfect, the central bead being practically non-existent, while beads of ends are formed simultaneously with the natural shrinkage.

Sur la figure 4, le débit de droite est nettement plus important que celui de gauche. Le retreint à gauche est très prononcé. Malgré cela, on constate que, grâce au coin de liaison, la continuité du rideau est toujours assurée.In FIG. 4, the flow rate on the right is clearly greater than that on the left. The constriction on the left is very pronounced. Despite this, it can be seen that, thanks to the connection corner, the continuity of the curtain is still ensured.

L'invention ne se limite pas au dispositif décrit ci-dessus à titre d'exemple. En particulier, les fentes des caissons ne sont pas nécessairement alignées. Elles peuvent, par exemple, être disposées en dents de scie, tout en restant chacune dans un plan perpendiculaire à la direction d'écoule­ment.The invention is not limited to the device described above by way of example. In particular, the slots in the boxes are not necessarily aligned. They can, for example, be arranged in a sawtooth pattern, while each remaining in a plane perpendicular to the direction of flow.

Les coins de liaisons visibles sur les figures 2 à 4 sont réalisés dans une feuille de caoutchouc découpée en triangle isocèle. Les côtés du triangle sont rectilignes. Ainsi que cela est représenté sur le dessin de la figure 1, il peut être avantageux de prévoir ces côtés légèrement courbes, l'important étant que l'angle au sommet soit infé­rieur à un angle maximum pour lequel il pourrait y avoir décollement du rideau en amont de la pointe du triangle.The connection corners visible in Figures 2 to 4 are made of a rubber sheet cut into an isosceles triangle. The sides of the triangle are straight. As shown in the drawing in Figure 1, it may be advantageous to provide these slightly curved sides, the important thing being that the apex angle is less than a maximum angle for which there could be detachment of the curtain in upstream of the tip of the triangle.

Dans certains cas également, on pourra prévoir un triangle non isocèle, privilégiant ainsi l'élargissement d'un rideau élémentaire par rapport à son voisin.In certain cases also, it is possible to provide for a non-isosceles triangle, thus favoring the widening of an elementary curtain with respect to its neighbor.

D'autre part, l'effet de guidage du bord du rideau étant assuré uniquement par le bord du coin, on pourra évider celui-ci en ne conservant en fait que les deux bords se rejoignant en formant un angle aigu et appointé.On the other hand, the effect of guiding the edge of the curtain being provided only by the edge of the corner, it can be hollowed out while in fact only retaining the two edges meeting at an acute and pointed angle.
