- the seal between the refractory plate and the front surfaces of the cylinders is deteriorated at the start of the casting.

- the refractory plate may also include, in the area between the cylinders, a projection penetrating between them, or a hollow.
Abstract
Description
La présente invention a pour objet une cassette destinée à former une face de fermeture frontale d'un dispositif de coulée continue de métal liquide entre deux cylindres parallèles, notamment d'acier liquide, suivant le préambule de la revendication 1.The subject of the present invention is a cassette intended to form a front closing face of a device for continuously casting liquid metal between two parallel cylinders, in particular liquid steel, according to the preamble of
On sait que les cassettes de ce type, telles que décrites dans le document JP-A-57130743, comportent une enveloppe métallique, ouverte sur l'un de ses côtés et ayant par conséquent un profil en C, dans lequel est logée une plaque de matériau réfractaire. Cette plaque peut être préchauffée avant la coulée du métal liquide.It is known that cassettes of this type, as described in document JP-A-57130743, comprise a metal casing, open on one of its sides and consequently having a C-shaped profile, in which a plate is housed. refractory material. This plate can be preheated before the molten metal is poured.
L'une des faces du bloc réfractaire est donc en appui sur le fond de l'enveloppe tandis que sa face opposée est en contact avec le métal liquide. Lors de la coulée, la plaque réfractaire s'échauffe au contact du métal en fusion et donc se dilate. Comme la plaque réfractaire est bridée dans l'enveloppe rigide et plus froide qui l'entoure, elle a tendance à se déformer par flambement, et perd donc sa planéité en prenant un bombé néfaste à l'étanchéité entre celles-ci et les faces frontales des cylindres. On constate alors qu'il se produit parfois des infiltrations de métal liquide entre les faces frontales des cylindres et les cassettes de fermeture.One of the faces of the refractory block is therefore in abutment on the bottom of the envelope while its opposite face is in contact with the liquid metal. During casting, the refractory plate heats up on contact with the molten metal and therefore expands. As the refractory plate is clamped in the rigid and cooler envelope which surrounds it, it tends to deform by buckling, and therefore loses its flatness by taking a bulge which is harmful to the seal between them and the front faces. cylinders. It can then be seen that infiltration of liquid metal sometimes occurs between the front faces of the cylinders and the closing cassettes.
Par ailleurs, le fond de l'enveloppe est généralement ajouré afin de permettre le préchauffage de la plaque réfractaire par un brûleur. Le préchauffage de la plaque réfractaire avant la coulée est effectué sur sa face externe, pour éviter de détériorer les surfaces des cylindres par les moyens de chauffage. Ce préchauffage est souhaitable pour mettre le réfractaire en température et éviter une solidification trop rapide du métal coulé à son contact en début de coulée. Il permet de plus d'éviter des chocs thermiques trop brutaux lors du premier contact avec le métal liquide.Furthermore, the bottom of the envelope is generally perforated in order to allow preheating of the refractory plate by a burner. Preheating of the refractory plate before casting is carried out on its external face, to avoid damaging the surfaces of the cylinders by the heating means. This preheating is desirable to bring the refractory to temperature and avoid too rapid solidification of the cast metal in contact with it at the start of casting. It also makes it possible to avoid thermal shock too brutal during the first contact with the liquid metal.
Mais ce préchauffage provoque une différence de température entre la surface du réfractaire directement soumise au chauffage et sa surface froide opposée. Cette différence de température entraîne une dilatation différentielle entre la surface chaude et la surface froide du réfractaire, qui provoque un cintrage ou un bombage de l'ensemble de la cassette, avant même le début de la coulée. Dans ce cas, l'étanchéité entre la plaque réfractaire et les surfaces frontales des cylindres est détériorée au départ de la coulée. Cette déformation due à la dilatation différentielle des deux faces du réfractaire se résorbe en principe en cours de coulée après la mise en régime thermique du fait que la plaque refractaire est alors échauffée du côté de sa face interne par le métal coulé, ce qui a pour effet de compenser plus ou moins la déformation créée au départ par le préchauffage. Néanmoins la dilatation globale de la plaque réfractaire subsiste et le problème du flambement de cette plaque, dû au fait qu'elle est bridée dans son enveloppe subsiste également.However, this preheating causes a temperature difference between the surface of the refractory directly subjected to heating and its opposite cold surface. This temperature difference leads to a differential expansion between the hot surface and the cold surface of the refractory, which causes bending or bending of the entire cassette, even before the start of casting. In this case, the seal between the refractory plate and the front surfaces of the cylinders is deteriorated at the start of the casting. This deformation due to the differential expansion of the two faces of the refractory is absorbed in principle during casting after the thermal regime due to the fact that the refractory plate is then heated on the side of its internal face by the cast metal, which has for more or less compensate for the deformation created at the start by preheating. However, the overall expansion of the refractory plate remains and the problem of buckling of this plate, due to the fact that it is clamped in its envelope also remains.
L'invention a donc pour but de résoudre ce problème en réalisant une cassette selon le préambule de la Revendication 1, du type décrit dans le document JP-A-57130743, agencée de manière à autoriser la libre dilatation de la plaque réfractaire, et ainsi d'éviter au moins les déformations dues au flambement.The invention therefore aims to solve this problem by producing a cassette according to the preamble of
Suivant l'invention, la plaque réfractaire est préformée de manière à réserver un espace libre entre son pourtour et la paroi latérale de l'enveloppe, et la cassette est équipée de moyens de fixation et de serrage produisant leur effet sur le pourtour de la plaque réfractaire, à action antagoniste élastique s'exerçant dans un plan parallèle au plan général de la plaque et permettant une libre dilatation dans l'enveloppe de la plaque réfractaire lors de son échauffement.According to the invention, the refractory plate is preformed so as to reserve a free space between its periphery and the side wall of the envelope, and the cassette is equipped with fixing and clamping means producing their effect on the periphery of the plate. refractory, with elastic antagonistic action exerted in a plane parallel to the general plane of the plate and allowing free expansion in the envelope of the refractory plate during its heating.
On comprend aisément que le fait de permettre cette libre dilatation limite le bombage de la plaque réfractaire, susceptible de provoquer des infiltrations de métal liquide par réduction de la surface de contact entre les cylindres et la cassette. En effet, ce résultat est obtenu grâce au maintien de la planéité de la face du réfractaire tournée vers le métal liquide. Ce maintien de la planéité et par conséquent de l'étanchéité vis-à-vis du métal liquide est lui-même étroitement lié à la possibilité de libre dilatation de la plaque réfractaire dans des directions parallèles au plan de sa face interne. Les déformations dues aux éventuelles dilatations différentielles ne pourront pas être totalement suprimées ; mais comme on l'a vu précédemment, ces déformations se résorbent au moins partiellement lorsque le régime thermique est stabilisé.It is easily understood that allowing this free expansion limits the bending of the refractory plate, capable of causing liquid metal infiltration by reducing the contact surface between the cylinders and the cassette. Indeed, this result is obtained by maintaining the flatness of the surface of the refractory facing the liquid metal. This maintenance of the flatness and consequently of the tightness with respect to the liquid metal is itself closely linked to the possibility of free expansion of the refractory plate in directions parallel to the plane of its internal face. Deformations due to possible differential expansions cannot be completely removed; but as we have seen previously, these deformations are at least partially absorbed when the thermal regime is stabilized.
Par ailleurs, l'élasticité des moyens de fixation de la plaque réfractaire permet aussi d'assurer le maintien de celle-ci-au cas où l'enveloppe se dilaterait plus que ladite plaque réfractaire.Furthermore, the elasticity of the means of fixing the refractory plate also makes it possible to ensure that the latter is maintained in the event that the envelope expands more than said refractory plate.
Suivant un mode de réalisation de l'invention, lesdits moyens de fixation et de serrage comprennent des vis traversant la paroi latérale périphérique de l'enveloppe et munies à leurs extrémités d'éléments élastiques fixés à la plaque réfractaire, tels que des rondelles Belleville.According to one embodiment of the invention, said fixing and tightening means comprise screws passing through the peripheral lateral wall of the envelope and provided at their ends with elastic elements fixed to the refractory plate, such as Belleville washers.
D'autres particularités et avantages de l'invention apparaîtront au cours de la description qui va suivre, faite en référence aux dessins annexés qui en illustrent une forme de réalisation à titre d'exemple non limitatif.Other features and advantages of the invention will become apparent during the description which follows, given with reference to the appended drawings which illustrate an embodiment thereof by way of nonlimiting example.
La figure 1 est une vue simplifiée partielle de dessus d'un dispositif de coulée continue de métal liquide entre deux cylindres et de l'une de ses cassettes de fermeture à ses extrémités.Figure 1 is a partial simplified view from above of a device for continuously casting liquid metal between two cylinders and one of its closing cassettes at its ends.
La figure 2 est une vue en élévation agrandie de la cassette de la Fig.1 du côté de sa plaque réfractaire.Figure 2 is an enlarged elevational view of the cassette of Fig.1 from the side of its refractory plate.
La figure 3 est une vue en coupe suivant 3/3 de la Fig.2Figure 3 is a sectional view along 3/3 of Fig.2
On voit à la Fig.1 un dispositif de coulée continue de métal liquide dans un espace libre 1 réservé entre deux cylindres parallèles 2, dont les faces frontales 2a sont situées dans un même plan vertical. Un tel dispositif est connu en soi et ne nécessite pas de description détaillée.We see in Fig.1 a device for continuously casting liquid metal in a
A chaque extrémité du cylindre 2, la fermeture de l'espace 1 est assurée par une cassette 3 constituée d'une enveloppe métallique 4 rigide et éventuellement refroidie, en forme de cuvette, ouverte sur son côté tourné vers les cylindres 2, et d'une plaque ou bloc réfractaire 5 logé à l'intérieur de l'enveloppe 4.At each end of the
Cette dernière, de contour rectangulaire dans l'exemple représenté, possède un fond 4a, parallèle aux faces frontales 2a, et une paroi latérale périphérique 4b coudée à angle droit, dimensionnée pour recevoir la plaque 5. Le fond 4a est perçé d'un ajour central 6 découvrant une partie correspondante de la plaque réfractaire 5, qui doit être préchauffée par un brûleur 7.The latter, of rectangular outline in the example shown, has a bottom 4a, parallel to the front faces 2a, and a peripheral side wall 4b bent at right angles, dimensioned to receive the
La plaque réfractaire 5 est préformée de manière à réserver un espace libre 8 entre son pourtour et la paroi périphérique 4b de l'enveloppe 4 (le bloc 5 étant donc dans cet exemple rectangulaire). Complémentairement la cassette 3 est équipée de moyens de fixation et de serrage de la plaque réfractaire 5 dans l'enveloppe 4. Dans l'exemple représenté, ces moyens sont constitués par une série de vis 9 traversant la paroi périphérique 4b et munies à leurs extrémités d'éléments élastiques 11 fixés en appui sur les côtés de la plaque réfractaire 5. Ces éléments élastiques 11 peuvent être avantageusement des rondelles Belleville, réparties ainsi que les vis correspondantes 9 en nombre convenable autour de la plaque 5, par exemple à raison de deux par côté (Fig.2).The
L'échauffement de la plaque réfractaire 5 par le brûleur 7 ou par le contact du métal en fusion provoque une libre dilatation de la plaque 5 dans le volume libre 8. Les rondelles Belleville 11 exercent sur les côtés du bloc 5 une action antagoniste élastique tout en autorisant sa dilatation dans des directions parallèles à son plan général et à celui des faces frontales 2a. Grâce à cette libre dilatation à l'intérieur de l'enveloppe métallique 4, la plaque réfractaire 5 n'est plus soumise au flambement et la face interne 5a de la plaque 5 conserve sensiblement sa planéité, ce qui permet l'obtention et le maintien de l'étanchéité souhaitée entre les faces frontales 2a et cette face interne 5a. Ainsi est pratiquement évité tout risque d'infiltration de métal liquide entre les faces 5a et 2a durant la coulée.The heating of the
En variante, le fond 4a de l'enveloppe 4 peut ne pas être ajouré et donc être constitué par une tôle pleine, si le préchauffage est effectué par rayonnement. Le fond 4a joue alors le rôle d'un diffuseur thermique pour homogénéiser l'apport de chaleur à la masse réfractaire 5 préchauffée.Alternatively, the bottom 4a of the
L'invention n'est pas limitée à la disposition décrite ci-dessus à titre d'exemple.The invention is not limited to the arrangement described above by way of example.
En particulier, elle s'applique aussi au cas où la paroi latérale 4b de l'enveloppe 4 n'est pas continue et ne comporte que trois côtés. Cette disposition est utilisable notamment dans le cas où les surfaces frontales 2a des cylindres sont axialement décalées l'une par rapport à l'autre, la plaque réfractaire 5 étant alors en contact, d'une part, par sa surface 5a, avec la face frontale de l'un des cylindres, et d'autre part, par son chant situé du côté où la paroi latérale 4b est interrompue, avec la surface cylindrique de l'autre cylindre; la plaque réfractaire est bien sûr alors conformée de manière que ledit chant épouse la courbure de cette surface cylindrique.In particular, it also applies to the case where the side wall 4b of the
Par ailleurs la plaque réfractaire peut aussi comporter, dans la zone située entre les cylindres, une saillie pénétrant entre ceux-ci, ou un creux.Furthermore, the refractory plate may also include, in the area between the cylinders, a projection penetrating between them, or a hollow.
