Definitions
- the present invention relates to the manufacture of ribbons which are rapidly quenched, called soaked ribbons, by spraying a liquid jet of the product to be soaked - metal or alloy - onto a cooled strip traveling at high speed. It concerns more particularly the technique according to which the contacting of the jet with the strip is carried out in an atmosphere at reduced pressure.
- Such a structure presupposes the production and maintenance in state of vacuum tight seals at the points of penetration of said crucible and of said winding through the wall of the enclosure.
- This structure also implies that the enclosure is all the more voluminous and complex as the crucible is of greater capacity, because it is then necessary to pay special attention to the sealing of the enclosure and the holding in place of the crucible (to balance the forces exerted on the joint by atmospheric pressure), as well as the means of insulation and cooling.
- the invention aims to eliminate these constraints.
- the subject of the present invention is, in a device for hyper-tempering a metal or alloy in the molten state by spraying a jet of the product to be hyper-tempered, from a crucible, in the direction of a cooled strip moving at high speed inside an enclosure under reduced pressure, the improvement consisting in that said crucible is dis placed outside said enclosure, above the latter, the lower part of said crucible, provided with a pouring orifice, resting in leaktight manner on the edge of an opening made for this purpose at the upper part or in the cover of said enclosure.
- said rim has a base of a shape complementary to that of the bottom of the crucible.
- a seal or a sealing washer, of suitable shape, is preferably interposed between said seat and said bottom.
- this sealing washer is made of a material which is a poor conductor of heat.
- Another embodiment consists in using, to constitute the seat, a piece of material which is a poor conductor of heat, and in running in the crucible in contact with said seat.
- FIG. 1 on which a moving strip 1 is seen, driven at high speed by means not shown, above a shoe 2 comprising, over at least part of its length, a box 2a, 2b for gas cushion with Coanda effect and, below a vacuum enclosure 3, one or more vacuum sockets 4, connected to a vacuum pumping assembly, not shown.
- the enclosure 3 comprises a tubular support 5, forming an integral part of its cover 6 and whose upper end forming a rim 5 ′ is machined so that the bottom of a crucible 7 can be applied to it with good seating, with interposition, preferably, of a washer 8 made of refractory fibers, ensuring sealing and thermal insulation.
- the side walls of the vacuum enclosure 3 bear, at their lower part, on the upper face of the shoe 2, the inlet part 9 and the outlet part 10 comprising, in the lower part, a niche of dimensions and shape suitable (not shown), constituting, with the upper face of the shoe 2, a slot, respectively for the entry of the strip 1 and for the exit of this strip carrying the hyper-dipped tape 11.
- the parts 9 and 10 include seals for sealing on the enclosure 3 and can be erased, for example by sliding upwards, in the event of an incident, for example in the event of the tape sticking to the strip.

- Additional means for melting and supplying molten product to said crucible 7, means not shown in FIG. 1, are advantageously arranged above the crucible to facilitate continuous operation of the installation. They allow in particular a regulation of the level of the product contained in the crucible 7, as well as the control of the nature and the pressure of the atmosphere surmounting the product in said crucible.
- the outlet part 10 may comprise, as patent application 80 15 918 has described, a wing at right angles to the wall itself, wing forming a tunnel or canopy over the ribbon towards the point of impact (I) of the liquid jet with the moving band.
- annular groove 21 for example of trapezoidal section, has been formed in the thickness of the upper part of the tubular support 5, preferably near the external lateral surface of the latter.
- the groove 21 thus allows a homogeneous distribution of the gas introduced (nitrogen, hydrogen, argon or, preferably, helium) through a tube 22.
- the material constituting the seal 8 being permeable to gas, it is thus possible to oppose the entry of air in the enclosure and control the atmosphere in which the product to be hyper-soaked is poured.

Description
La présente invention concerne la fabrication de rubans trempés rapidement, dits hypertrempés, par projection d'un jet liquide du produit à hypertremper -métal ou alliage- sur une bande refroidie défilant à grande vitesse. Elle intéresse plus spécialement la technique selon laquelle la mise en contact du jet avec la bande est réalisée dans une atmosphère à pression réduite.The present invention relates to the manufacture of ribbons which are rapidly quenched, called soaked ribbons, by spraying a liquid jet of the product to be soaked - metal or alloy - onto a cooled strip traveling at high speed. It concerns more particularly the technique according to which the contacting of the jet with the strip is carried out in an atmosphere at reduced pressure.
Dans la demande de brevet déposée en France le 18 Juillet 1980, sous le n° 80 15 918, est décrit un dispositif comprenant une boite à vide, traversée par la bande mobile, dans laquelle sont insérés non seulement un creuset muni d'un orifice d'éjection du jet liquide, mais l'enroulement pour le chauffage par induction à haute fréquence du produit contenu dans le creuset.In the patent application filed in France on July 18, 1980, under the number 80 15 918, a device is described comprising a vacuum box, crossed by the movable band, in which are inserted not only a crucible provided with an orifice liquid jet ejection, but the winding for high frequency induction heating of the product contained in the crucible.
Une telle structure suppose la réalisation et le maintien en état de joints étanches au vide aux points de pénétration dudit creuset et dudit enroulement au travers de la paroi de l'enceinte. Cette structure implique en outre que l'enceinte soit d'autant plus volumineuse et complexe que le creuset est de plus grande capacité, car il faut alors soigner tout spécialement l'étanchéité de l'enceinte et le maintien en place du creuset (pour équilibrer les efforts exercés sur le joint par la pression atmosphérique), ainsi que les moyens d'isolation et de refroidissement.Such a structure presupposes the production and maintenance in state of vacuum tight seals at the points of penetration of said crucible and of said winding through the wall of the enclosure. This structure also implies that the enclosure is all the more voluminous and complex as the crucible is of greater capacity, because it is then necessary to pay special attention to the sealing of the enclosure and the holding in place of the crucible (to balance the forces exerted on the joint by atmospheric pressure), as well as the means of insulation and cooling.
L'invention vise à éliminer ces sujétions.The invention aims to eliminate these constraints.
A cet effet, la présente invention a pour objet, dans un dispositif d'hypertrempe d'un métal ou alliage à l'état fondu par projection d'un jet du produit à hypertremper, à partir d'un creuset, en direction d'une bande refroidie se déplaçant à grande vitesse à l'intérieur d'une enceinte sous pression réduite, le perfectionnement consistant en ce que ledit creuset est disposé à l'extérieur de ladite enceinte, au-dessus de celle-ci, la partie inférieure dudit creuset, munie d'un orifice de coulée, reposant de façon étanche sur le rebord d'une ouverture ménagée dans ce but à la partie supérieure ou dans le couvercle de ladite enceinte.To this end, the subject of the present invention is, in a device for hyper-tempering a metal or alloy in the molten state by spraying a jet of the product to be hyper-tempered, from a crucible, in the direction of a cooled strip moving at high speed inside an enclosure under reduced pressure, the improvement consisting in that said crucible is dis placed outside said enclosure, above the latter, the lower part of said crucible, provided with a pouring orifice, resting in leaktight manner on the edge of an opening made for this purpose at the upper part or in the cover of said enclosure.
Dans une forme avantageuse de réalisation, ledit rebord comporte une assise de forme complémentaire de celle du fond du creuset. Un joint ou une rondelle d'étanchéité, de forme adaptée, est de préférence interposé entre ladite assise et ledit fond. Avantageusement, cette rondelle d'étanchéité est constituée d'un matériau mauvais conducteur de la chaleur.In an advantageous embodiment, said rim has a base of a shape complementary to that of the bottom of the crucible. A seal or a sealing washer, of suitable shape, is preferably interposed between said seat and said bottom. Advantageously, this sealing washer is made of a material which is a poor conductor of heat.
Une autre forme de réalisation consiste à utiliser pour constituer l'assise, une pièce en matériau mauvais conducteur de la chaleur, et à effectuer un rodage du creuset au contact de ladite assise. On peut d'ailleurs, avantageusement encore, choisir pour les surfaces ainsi rodées une géométrie plane.Another embodiment consists in using, to constitute the seat, a piece of material which is a poor conductor of heat, and in running in the crucible in contact with said seat. One can also, advantageously still, choose for the surfaces thus ground a plane geometry.
Les dessins schématiques annexés, qui n'ont pas de caractère limitatif, illustrent la mise en oeuvre de l'invention. Sur ces dessins :
- La figure 1 est une coupe partielle du dispositif d'hypertrempe conforme à l'invention ;
- La figure 2 est une vue de détail, à plus grande échelle, d'une variante du dispositif selon l'invention
- Les figures 3 et 4 sont des coupes de deux types d'enceintes à vide utilisables dans le dispositif conforme à l'invention.
- Figure 1 is a partial section of the hyperhardening device according to the invention;
- Figure 2 is a detail view, on a larger scale, of a variant of the device according to the invention
- Figures 3 and 4 are sections of two types of vacuum chambers used in the device according to the invention.
On se référera d'abord à la figure 1, sur laquelle on voit une bande mobile 1, entraînée à grande vitesse par des moyens non représentés, au-dessus d'un sabot 2 comportant, sur au moins une partie de sa longueur, un caisson 2a, 2b pour coussin gazeux à effet Coanda et, au-dessous d'une enceinte à vide 3, une ou plusieurs prises de vide 4, reliées à un ensemble de pompage pour vide, non représenté.Reference will first be made to FIG. 1, on which a moving strip 1 is seen, driven at high speed by means not shown, above a shoe 2 comprising, over at least part of its length, a
L'enceinte 3 comporte un support tubulaire 5, faisant partie intégrante de son couvercle 6 et dont l'extrémité supérieure formant rebord 5' est usinée de manière que puisse s'y appliquer avec une bonne assise le fond d'un creuset 7, avec interposition, de préférence, d'une rondelle 8 en fibres réfractaires, assurant l'étanchéité et l'isolation thermique.The enclosure 3 comprises a
Les parois latérales de l'enceinte à vide 3 prennent appui, à leur partie inférieure, sur la face supérieure du sabot 2, la pièce d'entrée 9 et la pièce de sortie 10 comportant, en partie basse, un créneau de dimensions et forme appropriées (non représenté), constituant, avec la face supérieure du sabot 2, une fente, respectivement pour l'entrée de la bande 1 et pour la sortie de cette bande portant le ruban hyper- trempé 11. Les pièces 9 et 10 comportent des joints pour étanchéité sur l'enceinte 3 et peuvent s'effacer, par exemple par coulissement vers le haut, en cas d'incident, par exemple en cas de collage du ruban sur la bande.The side walls of the vacuum enclosure 3 bear, at their lower part, on the upper face of the shoe 2, the inlet part 9 and the
Un inducteur 12, disposé autour de l'extrémité inférieure du creuset 7, permet le chauffage par induction haute fréquence du produit à hypertremper 13 contenu dans le creuset et évacué de celui-ci par un orifice de coulée 14, en direction de la bande 1, pour y former le ruban 11. Des moyens complémentaires de fusion et d'alimentation en produit fondu dudit creuset 7, moyens non représentés sur la figure 1, sont avantageusement disposés au-dessus du creuset pour faciliter un fonctionnement continu de l'installation. Ils permettent notamment une régulation du niveau du produit contenu dans le creuset 7, ainsi que la maîtrise de la nature et de la pression de l'atmosphère surmontant le produit dans ledit creuset.An inductor 12, disposed around the lower end of the crucible 7, allows the high-frequency induction heating of the product to be soaked 13 contained in the crucible and evacuated from it by a pouring orifice 14, in the direction of the strip 1 , to form the
La pièce de sortie 10 peut comporter, comme la demande de brevet 80 15 918 l'a décrit, une aile en équerre par rapport à la paroi proprement dite, aile formant tunnel ou auvent au-dessus du ruban en direction du point d'impact (I) du jet liquide avec la bande mobile.The
En l'absence d'une aile en équerre, on peut utiliser une pièce de sortie 10 plane, susceptible d'être montée sur charnière et de fonctionner,ainsi, comme un volet de sécurité s'ouvrant en cas de bourrage, puis reprenant sa position de lui-même après l'incident, et étant plaqué sur son joint d'étanchéité sous l'effet du vide réalisé dans l'enceinte. Ce même effet assure, de la même façon, l'étanchéité entre divers autres éléments de la paroi de l'enceinte -pièce d'entrée 9, éventuels hublots d'observation (non représentés)- et également entre le fond du creuset 7 et le support tubulaire 5.In the absence of a square wing, it is possible to use a
On remarquera que la structure du dispositif perfectionné selon l'invention apporte notamment les avantages suivants concernant le creuset :
- a) facilité d'alimentation en continu du creuset,
- b) facilité de remplacement du creuset (même éventuellement par un creuset de diamètre différent, en ne changeant que l'inducteur),
- c) moindres exigences quant aux performances des matériaux utilisés et à la précision de la fabrication du creuset, celui-ci pouvant d'ailleurs avoir des formes très variées,
- d) réduction des contraintes mécaniques, éventuellement d'origine thermique, du fait du report du joint d'étanchéité de sa partie cylindrique à sa base, et de l'homogénéité de température de l'ensemble du creuset.
- a) ease of continuous supply of the crucible,
- b) easy replacement of the crucible (even possibly with a crucible of different diameter, changing only the inductor),
- c) lower requirements as to the performance of the materials used and the precision of the crucible's manufacture, this crucible can moreover have very varied shapes,
- d) reduction of mechanical stresses, possibly of thermal origin, due to the transfer of the gasket from its cylindrical part to its base, and the temperature uniformity of the whole crucible.
En ce qui concerne l'enceinte sous vide, il n'est plus nécessaire de la refroidir énergiquement, et elle peut être fabriquée très facilement, ainsi qu'on le montrera ci-après en référence aux figures.As regards the vacuum enclosure, it is no longer necessary to cool it vigorously, and it can be manufactured very easily, as will be shown below with reference to the figures.
Au niveau du joint situé entre le fond du creuset 7 et le rebord 5' du support tubulaire 5, par lequel peut se produire sous l'effet de la dépression, éventuellement, compte tenu des différences de température entre pièces en contact, une entrée de gaz vers l'enceinte à vide, un balayage par un gaz choisi,notamment, pour ses propriétés contre l'oxydation, peut être avantageusement prévu. A cet effet, on peut notamment utiliser la variante de support tubulaire représentée sur la figure 2, où les organes déjà décrits conservent les mêmes références.At the joint located between the bottom of the crucible 7 and the flange 5 'of the
Dans cette variante, une rainure annulaire 21, par exemple de section trapézoïdale, a été ménagée dans l'épaisseur de la partie supérieure du support tubulaire 5, de préférence à.proximité de la surface latérale extérieure de celui-ci. La rainure 21 permet ainsi une répartition homogène du gaz introduit (azote, hydrogène, argon ou,de préférence, hélium) par un tube 22. Le matériau constituant le joint 8 étant perméable au gaz, on peut ainsi s'opposer à l'entrée d'air dans l'enceinte et contrôler l'atmosphère dans laquelle s'effectue la coulée de produit à hypertremper.In this variant, an
Les figures 3 et 4 représentent des exemples particuliers d'enceintes à vide conformes à l'invention.Figures 3 and 4 show particular examples of vacuum chambers according to the invention.
Dans ces deux variantes, un sas 31 est prévu en amont, dans le sens de déplacement de la bande mobile, de la chambre de coulée 32 proprement dite.In these two variants, an
Malgré les dimensions très réduites de l'enceinte, des hublots d'observation 33 peuvent être prévus latéralement dans l'enceinte, comme représenté sur la figure 4.Despite the very small dimensions of the enclosure,
On notera que les pièces d'entrée et de sortie, repérées 9 et.10 sur la figure 1, n'ont pas été représentées sur les figures 3 et 4, mais que la face destinée à prendre contact sur le sabot support est entaillée, à l'entrée et à la sortie, d'un créneau, respectivement 34 et 35, qui est masqué, en fonctionnement, par la pièce complémentaire, respectivement 9 à l'entrée et 10 à la sortie, précédemment décrite.It will be noted that the input and output parts, marked 9 and 10 in FIG. 1, have not been shown in FIGS. 3 and 4, but that the face intended to make contact on the support shoe is notched, at the entrance and at the exit, a slot, respectively 34 and 35, which is masked, in operation, by the complementary part, respectively 9 at the entry and 10 at the exit, previously described.
Le dispositif selon l'invention a permis de fabriquer des rubans de verres métalliques d'excellentes qualités de surface, et très bien trempés, en maintenant dans l'enceinte de coulée une pression réduite, de l'ordre du dixième d'atmosphère. Un débit d'hélium très faible, par exemple d'un litre par minute, suffit pour éviter toute entrée d'air au niveau du joint 8.The device according to the invention made it possible to manufacture quer ribbons of metallic glasses of excellent surface qualities, and very well tempered, maintaining in the casting enclosure a reduced pressure, of the order of a tenth of an atmosphere. A very low helium flow rate, for example of one liter per minute, is sufficient to avoid any entry of air at the
