Description

L'invention concerne un dispositif d'entraînement de produits longs en défilement et s'applique plus particulièrement à l'entraînement de ces produits lors du refroidissement auquel ils sont soumis après laminage.The invention relates to a device for driving long scrolling products and applies more particularly to the driving of these products during the cooling to which they are subjected after rolling.

Les produits longs, notamment les barres et les ronds à béton, à la sortie des cages finisseuses, subissent un refroidissement contrôlé destiné à leur conférer la structure et les caractéristiques mécaniques souhaitées. Ce traitement thermique est effectué sur les produits en défilement, leur entraînement étant généralement assuré par de simples rouleaux. Lorsque le refroidissement est effectué par aspersion d'eau au moyen de rampes de pulvérisation disposées au-dessus des produits, les rouleaux sont en nombre suffisant et régulièrement espacés et ils permettent au produit de conserver une vitesse élevée pendant toute la traversée de l'installation de refroidissement.Long products, in particular bars and concrete bars, at the exit of the finishing cages, undergo controlled cooling intended to give them the desired structure and mechanical characteristics. This heat treatment is carried out on the moving products, their drive being generally provided by simple rollers. When the cooling is carried out by sprinkling of water by means of spraying booms arranged above the products, the rollers are in sufficient number and regularly spaced and they allow the product to maintain a high speed throughout the crossing of the installation. cooling.

La tendance actuelle est cependant d'employer des dispositifs de refroidissement plus efficaces constitués essentiellement d'un tube de refroidissement, dans lequel le produit est entouré d'une lame d'eau circulant à grande vitesse. Le tube est équipé à l'une de ses extrémités d'une tête d'alimentation en eau et à l'autre d'un séparateur pour dissocier le produit de son enveloppe liquide. On peut ainsi, pour des produits de diamètre relativement grand, en acier soudable à bas carbone, suivre une loi de refroidissement suffisamment rapide pour que les caractéristiques mécaniques obtenues rendent non nécessaire un écrouissage ultérieur.The current trend, however, is to use more efficient cooling devices consisting essentially of a cooling tube, in which the product is surrounded by a sheet of water circulating at high speed. The tube is equipped at one end with a water supply head and at the other with a separator to dissociate the product from its liquid envelope. It is thus possible, for products of relatively large diameter, made of weldable low carbon steel, to follow a cooling law fast enough for the mechanical characteristics obtained to make subsequent work hardening unnecessary.

Toutefois, pendant la traversée des tubes, le produit ne peut plus être en contact avec des rouleaux, comme c'était le cas dans les installations munies de rampes d'aspersion, et dans certains cas, sa vitesse peut décroître de façon sensible.However, during the passage of the tubes, the product can no longer be in contact with rollers, as was the case in installations fitted with spray bars, and in some cases its speed can decrease significantly.

La présente invention a précisément pour but de remédier à cet inconvénient.The object of the present invention is precisely to remedy this drawback.

A cet effet, l'invention a pour objet un dispositif d'entraînement de produits longs en défilement entourés d'une enveloppe liquide. Il est constitué d'un galet porté par un axe disposé transversalement au sens de défilement du produit, placé à l'intérieur d'un caisson étanche et solidarisé aux parois latérales de ce dernier par des moyens permettant sa rotation, le caisson présentant deux orifices pour permettre le passage en ligne droite du produit.To this end, the invention relates to a device for driving long products in movement surrounded by a liquid envelope. It consists of a roller carried by an axis arranged transversely to the direction of travel of the product, placed inside a sealed box and secured to the side walls of the latter by means allowing its rotation, the box having two orifices to allow the product to pass in a straight line.

Selon une caractéristique du dispositif suivant l'invention, le caisson est constitué de deux parois latérales munies de deux paliers de roulement, supportant l'axe du galet, d'un fond et d'un couvercle.According to a characteristic of the device according to the invention, the box consists of two side walls provided with two rolling bearings, supporting the axis of the roller, a bottom and a cover.

Selon une autre caractéristique du dispositif selon l'invention, le couvercle présente sur sa paroi interne un canal semi-circulaire pour le passage du produit.According to another characteristic of the device according to the invention, the cover has on its internal wall a semi-circular channel for the passage of the product.

De préférence, le canal semi-circulaire est raccordé en amont, par rapport au sens du défilement du produit, à un passage percé d'un canal circulaire suivi d'un convergent et en aval, par rapport au sens de défilement du produit, à un passage percé d'un canal circulaire précédé d'un divergent.Preferably, the semicircular channel is connected upstream, relative to the direction of movement of the product, to a passage pierced with a circular channel followed by a convergent and downstream, relative to the direction of movement of the product, to a passage pierced with a circular channel preceded by a divergent.

De préférence, le galet porte une gorge annulaire à sa périphérie, le passage du produit s'effectuant entre le couvercle et cette gorge.Preferably, the roller carries an annular groove at its periphery, the passage of the product taking place between the cover and this groove.

Le galet peut être de section circulaire ou élliptique.The roller can be of circular or elliptical section.

Selon un mode de réalisation, l'axe du galet est relié à un moteur d'entraînement.According to one embodiment, the axis of the roller is connected to a drive motor.

L'invention a également pour objet une installation de refroidissement de produits longs en défilement comprenant un tube de refroidissement, où circulent le produit et une lame d'eau enveloppant ce dernier, ledit tube étant équipé à ses deux extrêmités respectivement d'une tête d'alimentation en eau et d'un séparateur eau-produit, un dispositif d'entraînement au moins tel qu'explicité ci-avant étant disposé dans le tube de refroidissement.The invention also relates to an installation for cooling long moving products comprising a cooling tube, where the product circulates and a sheet of water enveloping the latter, said tube being equipped at its two ends respectively with a head d water supply and a water-product separator, a drive device at least as explained above being arranged in the cooling tube.

Comme on le comprend, si la vitesse de défilement du produit varie au cours de son passage dans le tube de refroidissement, la loi de refroidissement suivie n'est pas partout la même et il en résulte une hétérogénéite de la structure et, par conséquent, des caractéristiques mécaniques le long du produit. Tant que le produit est en prise dans les cages finisseuses, sa vitesse reste constante, voisine de celle de rotation des cylindres. Une fois sorti de la dernière cage, sa vitesse décroît, mais tant que son extrémité repose sur un nombre suffisant de rouleaux, son entraînement est assuré et la diminution de vitesse est peu gênante ; par contre, lorsque seule une portion de faible longueur subsiste en amont de l'entrée du tube de refroidissement, le freinage du au frottement de la lame d'eau, même lorsque le produit et l'eau circulent à co-courant, devient sensible. II. est donc apparu nécessaire au demandeur de disposer, dans l'installation de refroidissement, des dispositifs permettant de conserver au produit une vitesse uniforme.As will be understood, if the speed of movement of the product varies during its passage through the cooling tube, the law of cooling followed is not everywhere the same and this results in heterogeneity of the structure and, consequently, mechanical characteristics along the product. As long as the product is engaged in the finishing cages, its speed remains constant, close to that of rotation of the cylinders. Once out of the last cage, its speed decreases, but as long as its end rests on a sufficient number of rollers, its drive is ensured and the reduction in speed is not a problem; on the other hand, when only a short portion remains upstream of the inlet of the cooling tube, the braking due to the friction of the water layer, even when the product and the water circulate co-current, becomes sensitive . II. It therefore appeared necessary to the applicant to have, in the cooling installation, devices allowing the product to be kept at a uniform speed.

Un autre phénomène cause des hétérogénéités locales de refroidissement - et donc de structure : la venue en contact du produit avec les parois cu tube de refroidissement. En effet, les produits, en particulier ceux d'assez fort diamètre, présentent une flèche suffisamment importante pour venii reposer sur le fond du tube. Pour y remédier, le demandeur a déjà propcsé de disposer, à l'intérieur du tube de refroidissement, des dispositifs de centrage constitués essentiellement d'un élément tubulaire comportant un passage central de diamètre interne inférieur au diamètre interne du tube et présentant des canaux longitudinaux répartis autour du passage central. Afin d'éviter à la fois les hétérogénéités le long du produit et les hétérogénéités locales, le demandeur a donc été amené à disposer les dispositifs d'entraînement, non pas n'importe où dans l'installation, mais en remplacement de tout ou partie des dispositifs de centrage, leur conférant ainsi une double fonction.Another phenomenon causes local heterogeneities of cooling - and therefore of structure: the coming into contact of the product with the walls or cooling tube. Indeed, the products, in particular those of fairly large diameter, have a sufficiently large deflection to come to rest on the bottom of the tube. To remedy this, the applicant has already proposed to have, inside the cooling tube, centering devices essentially consisting of a tubular element comprising a central passage with an internal diameter less than the internal diameter of the tube and having longitudinal channels distributed around the central passage. In order to avoid both heterogeneities along the product and local heterogeneities, the applicant was therefore led to arrange the drive devices, not anywhere in the installation, but in replacement of all or part centering devices, thereby giving them a dual function.

L'invention sera de toutes façons bien comprise au vu de l'exemple qui va suivre, donné à titre purement illustratif, en référence aux planches de dessin annexées sur lesquelles :

  • - la figure 1 est une coupe transversale du dispositif selon l'invention,
  • - la figure 2 représente le même dispositif en coupe longitudinale.
The invention will in any case be clearly understood in the light of the example which follows, given purely by way of illustration, with reference to the attached drawing boards on which:
  • FIG. 1 is a cross section of the device according to the invention,
  • - Figure 2 shows the same device in longitudinal section.

La description sera faite en référence aux deux figures simultanément et les éléments identiques seront désignés par le même repère.The description will be made with reference to the two figures simultaneously and the identical elements will be designated by the same reference.

Le dispositif d'entraînement selon l'invention est essentiellement constitué par un galet 1 disposé à l'intérieur d'un caisson étanche 2 et mis en rotation par un moteur 3. Le caisson est constitué d'un fond 4, de deux parois latérales 5 et 6 et d'un couvercle 7. La galet 1 est monté sur un axe 8 porté par deux paliers de roulement 9 et 10 disposés respectivement dans les parois latérales 5 et 6.The drive device according to the invention essentially consists of a roller 1 placed inside a sealed box 2 and rotated by a motor 3. The box consists of a bottom 4, two side walls 5 and 6 and a cover 7. The roller 1 is mounted on an axis 8 carried by two rolling bearings 9 and 10 disposed respectively in the side walls 5 and 6.

L'extrémité de l'axe portée par le roulement 10 traverse la paroi 6 et est reliée au moteur 3 qui assure la rotation de l'ensemble, à la vitesse choisie, dans le sens de défilement du produit. Ce dernier n'a pas été représenté, pour ne pas surcharger les figures, mais son sens de défilement est indiqué par une flèche sur la figure 2. L'autre extrémité de l'axe 8 est protégée par un capot Il fixé sur la paroi 5 par des vis telles que 12. Deux pièces en matériau élastique 13 et 14 assurent respectivement une liaison souple entre l'axe 8 et les parois 5 et 6.The end of the axis carried by the bearing 10 crosses the wall 6 and is connected to the motor 3 which ensures the rotation of the assembly, at the chosen speed, in the direction of travel of the product. The latter has not been shown, so as not to overload the figures, but its direction of travel is indicated by an arrow in FIG. 2. The other end of the axis 8 is protected by a cover II fixed on the wall 5 by screws such as 12. Two pieces of elastic material 13 and 14 respectively provide a flexible connection between the axis 8 and the walls 5 and 6.

Le couvercle 7 présente un évidement semi-cylindrique 15 destiné à servir de passage au produit. Ce couvercle 7 est raccordé au tube de refroidissement, comme on peut le voir sur la figure 2, par deux embouts 16 et 17 tubulaires. Dans le sens de défilement du produit, l'embout 16 présente un passage d'abord cylindrique prolongé par une partie convergente et l'embout 17 présente un passage cylindrique précédé par une partie convergente afin de faciliter l'introduction et la sortie du produit dans le dispositif. Le couvercle 7 est fixé sur les parois latérales par des vis telles que 18.The cover 7 has a semi-cylindrical recess 15 intended to serve as a passage for the product. This cover 7 is connected to the cooling tube, as can be seen in FIG. 2, by two tubular ends 16 and 17. In the direction of travel of the product, the end piece 16 has a first cylindrical passage extended by a converging part and the end piece 17 has a cylindrical passage preceded by a converging part in order to facilitate the introduction and the exit of the product into the device. The cover 7 is fixed to the side walls by screws such as 18.

Une gorge annulaire 19 est ménagée sur la périphérie du galet 1 afin d'assurer un meilleur contact avec le produit. Ce dernier, accompagné de son enveloppe liquide pénètre donc par l'embout 16, arrive en contact avec le galet et ressort par l'embout 17 à vitesse plus élevée. Le passage délimité par l'évidement 15 et la gorge 19 est de hauteur inférieure au diamètre intérieur du tube de refroidissement pour permettre au dispositif d'assurer sa fonction de centrage. Une partie de l'enveloppe liquide passe donc par l'espace délimité par le galet 1 et le fond 4 du caisson. Des joints toriques sont prévus partout où leur présence est nécessaire pour assurer l'étanchéité de l'ensemble.An annular groove 19 is formed on the periphery of the roller 1 in order to ensure better contact with the product. The latter, accompanied by its liquid envelope therefore penetrates through the nozzle 16, comes into contact with the roller and exits through the nozzle 17 at higher speed. The passage delimited by the recess 15 and the groove 19 is less than the inside diameter of the cooling tube to allow the device to perform its centering function. Part of the liquid envelope therefore passes through the space delimited by the roller 1 and the bottom 4 of the box. O-rings are provided wherever their presence is necessary to seal the assembly.

Il va de soi que la présente invention n'est pas limitée, dans sa portée, à l'exemple décrit, le galet peut notamment être de section élliptique afin de conférer au produit un mouvement latéral pour déstabiliser les films de vapeur pouvant éventuellement se former. De même, on peut prévoir de disposer aux extrémités de la gorge des pales afin d'éviter que de l'eau ne stagne au fond du caisson.It goes without saying that the present invention is not limited, in its scope, to the example described, the roller can in particular be of elliptical section in order to give the product a lateral movement to destabilize the vapor films which may possibly form. . Likewise, provision can be made to have blades at the ends of the groove in order to prevent water from stagnating at the bottom of the box.

Le nombre et la position des dispositifs selon l'invention n'est pas limité : ils peuvent remplacer un seul dispositif de centrage, cela peut suffire dans certains cas à conserver la vitesse constante, une partie ou la totalité de ces dispositifs. Les galets peuvent être placés sous le produit, comme dans l'exemple décrit, en quinconce, l'un en-dessous suivi d'un autre au-dessus, afin d'obtenir un effet de dressage. Deux galets superposés peuvent être disposés dans le même caisson, le produit passant entre les deux. Enfin, une partie ou la totalité des galets ne sont pas nécessairement entraînée par un moteur, leur rôle passif étant alors identique à celui joué par les rouleaux dont sont munies les installations de refroidissement classiques.The number and position of the devices according to the invention is not limited: they can replace a single centering device, this may be sufficient in certain cases to keep the speed constant, some or all of these devices. The rollers can be placed under the product, as in the example described, in staggered rows, one below followed by another above, in order to obtain a straightening effect. Two superimposed rollers can be placed in the same box, the product passing between the two. Finally, some or all of the rollers are not necessarily driven by a motor, their passive role then being identical to that played by the rollers with which conventional cooling installations are provided.
