Description

L'invention a pour objet une machine de coulée continue de métal, en particulier d'acier sous forme de blooms ou de brames.The subject of the invention is a machine for continuously casting metal, in particular steel in the form of blooms or slabs.

Une machine de coulée continue comprend de façon classique, une lingotière sans fond à parois énergiquement refroidies et un corset de refroidissement secondaire placé dans le prolongement de la lingotière. La lingotière doit être animé d'un mouvement d'oscillation tout en restant alignée le long d'une ligne de coulée et à cet effet, elle est portée par des moyens reliés à un mécanisme d'oscillation et en même temps guidée le long de la ligne de coulée. L'invention s'applique notamment aux installations de coulée courbe et l'on sait que, dans ce cas, la cavité de la lingotière forme un arc de cercle de même rayon que celui de la ligne de coulée définie par le corset courbe, les moyens de guidage étant agencés de façon que le mouvement d'oscillation se produise dans le prolongement de cette ligne courbe.A continuous casting machine conventionally comprises a bottomless ingot mold with energetically cooled walls and a secondary cooling corset placed in the extension of the ingot mold. The ingot mold must be made to oscillate while remaining aligned along a casting line and for this purpose it is carried by means connected to an oscillation mechanism and at the same time guided along the casting line. The invention applies in particular to curved casting installations and it is known that, in this case, the cavity of the ingot mold forms an arc of a circle of the same radius as that of the casting line defined by the curved brace, the guide means being arranged so that the oscillation movement occurs in the extension of this curved line.

Le corset de refroidissement, qui doit être assez rigide, peut être monté sur un châssis en forme de poutre courbe parallèle à la ligne de coulée et, pour permettre les dilatations en maintenant autant que possible l'alignement avec la lingotière, le châssis est monté souvent, à sa partie inférieure, sur un pivot d'axe orthogonal au plan médian du produit coulé et s'appuie à sa partie supérieure, au-dessous de la lingotière, sur une glissière fixe.The cooling corset, which must be fairly rigid, can be mounted on a chassis in the form of a curved beam parallel to the casting line and, to allow expansion while maintaining alignment with the mold as much as possible, the chassis is mounted often, at its lower part, on a pivot with an axis orthogonal to the median plane of the cast product and rests at its upper part, below the mold, on a fixed slide.

Jusqu'à présent, il était habituel de monter le mécanisme d'oscillation et le châssis du corset sur une structure de support formant une sorte d'échafaudage en construction métallique allant du niveau inférieur de sortie du corset de refroidissement secondaire jusqu'au plancher de coulée placé au niveau de la lingotière. Une telle structure est donc assez haute et risque de se déformer et en tout cas, elle est soumise à des vibrations engendrées par le mouvement d'oscillation.Until now, it was usual to mount the oscillation mechanism and the corset chassis on a support structure forming a kind of scaffolding in metal construction going from the lower exit level of the secondary cooling corset to the floor of casting placed at the level of the mold. Such a structure is therefore quite high and risks deforming and in any case, it is subjected to vibrations generated by the oscillation movement.

Pour réduire l'importance de la structure de support métallique, on a déjà eu l'idée d'appuyer la partie supérieure du corset de refroidissement sur un massif de fondation en béton dont la présence est souvent nécessaire de toutes façons pour supporter un appareil bien connu appelé pivoteur de poche qui amène les poches d'acier liquide au-dessus de la lingotière.To reduce the importance of the metal support structure, we have already had the idea of supporting the upper part of the cooling corset on a concrete foundation block whose presence is often necessary anyway to support a well known as a pocket pivot which brings the pockets of liquid steel above the mold.

Cependant, jusqu'à présent, le massif de fondation s'arrêtait au niveau de la glissière de guidage du corset de refroidissement et les organes d'oscillation et de guidage de la lingotière étaient montés sur le plancher de coulée. Il en résulte que, dans les installations de coulée à plusieurs lignes, les vibrations engendrées par l'oscillation de la lingotière pouvaient être transmises par le plancher de coulée et perturber le mouvement des mécanismes des lignes voisines.However, until now, the foundation block stopped at the level of the guide rail of the cooling corset and the oscillation and guide members of the mold were mounted on the floor of casting. As a result, in multi-line casting installations, the vibrations generated by the oscillation of the ingot mold could be transmitted by the casting floor and disturb the movement of the mechanisms of the neighboring lines.

Dans d'autres cas, le mécanisme d'oscillation est monté sur le châssis du corset de refroidissement secondaire mais alors les vibrations engendrées par l'oscillation de la lingotière sont transmises au corset de refroidissement et peuvent perturber la stabilité de l'alignement de la lingotière avec le corset.In other cases, the oscillation mechanism is mounted on the chassis of the secondary cooling corset but then the vibrations generated by the oscillation of the mold are transmitted to the cooling corset and can disturb the stability of the alignment of the ingot mold with corset.

L'invention a pour objet une nouvelle disposition qui permet d'éviter ces inconvénients en assurant l'absorption des vibrations avant quelles ne soient transmises au corset de refroidissement ou aux lignes de coulée voisines.The subject of the invention is a new arrangement which makes it possible to avoid these drawbacks by ensuring the absorption of vibrations before they are transmitted to the cooling corset or to the nearby casting lines.

Conformément à l'invention, le massif de fondation est prolongé vers le haut au moins jusqu'au niveau supérieur du châssis de support du corset et est muni à sa partie supérieure d'une plateforme sur laquelle sont fixés les moyens d'oscillation et de guidage de la lingotière.According to the invention, the foundation block is extended upward at least up to the upper level of the support frame of the corset and is provided at its upper part with a platform on which are fixed the oscillation and guiding the mold.

Dans un mode de réalisation préférentiel, la plateforme de fixation des moyens d'oscillation de guidage est constituée par un châssis métallique rigide fixé sur le massif de fondation et sur lequel est montée la glissière d'appui du châssis de support du corset.In a preferred embodiment, the platform for fixing the guide oscillation means is constituted by a rigid metal frame fixed on the foundation block and on which is mounted the support slide of the support frame of the corset.

Dans une installation de coulée continue à plusieurs lignes, les mécanismes d'oscillation et de guidage de deux machines voisines sont fixés sur deux massifs de fondation individuels entre lesquels est laissé un espace d'isolement.In a multi-line continuous casting installation, the oscillation and guidance mechanisms of two neighboring machines are fixed on two individual foundation blocks between which an isolation space is left.

Ainsi, selon l'invention, on supprime pratiquement la structure de support métallique sur laquelle étaient montés les moyens d'oscillation et de guidage pour la remplacer par un élément lourd qui peut être avantageusement un massif en béton et qui absorbe immédiatement les vibrations engendrées par l'oscillation avant que celles-ci ne soient transmises au corset de refroidissement ou aux lignes voisines.Thus, according to the invention, the metallic support structure on which the oscillation and guide means were mounted is practically eliminated to replace it with a heavy element which can advantageously be a concrete block and which immediately absorbs the vibrations generated by the oscillation before these are transmitted to the cooling corset or to the neighboring lines.

L'invention sera mieux comprise en se référant à un mode de réalisation particulier, donné à titre d'exemple et représenté sur les dessins annexés.

  • La figure 2 est une vue de c8té de la machine, le corset de refroidissement étant enlevé.
  • La figure 3 est une vue schématique de face de la machine représentée Fig 2, dans le cas d'une installation à plusieurs lignes.
The invention will be better understood by referring to a particular embodiment, given by way of example and shown in the accompanying drawings.
  • FIG. 1 is an elevation view of a machine according to the invention, in section through the median plane of the product, marked II in FIG. 3.
  • Figure 2 is a side view of the machine, the cooling brace being removed.
  • Figure 3 is a schematic front view of the machine shown in Figure 2, in the case of an installation with several lines.

Sur la figure 1, on a représenté une installation de coulée continue d'acier comportant de façon classique, une lingotière 1 montée sur une table oscillante 2 animée d'un mouvement d'oscillation par un levier 3 entrai- né par un mécanisme 20 monté sur un massif de fondation 4.In Figure 1, there is shown a continuous steel casting installation comprising in a conventional manner, a mold 1 mounted on an oscillating table 2 driven in an oscillating movement by a lever 3 driven by a mechanism 20 mounted on a foundation block 4.

Le corset de guidage est monté dans un châssis 5 en forme de poutre constituée, comme on le voit sur la figure 3, de deux longerons 51 reliés entre eux par des entretoises 52 sur lesquelles sont fixés des segments 50 du corset de guidage portant chacun deux paires de rouleaux et des rampes d'aspersion d'eau de refroidissementetentre lesquels est guidé le produit coulé A suivant une ligne de coulée 10.The guide corset is mounted in a chassis 5 in the form of a beam made up, as can be seen in FIG. 3, of two longitudinal members 51 connected together by spacers 52 on which are fixed segments 50 of the guide corset each carrying two pairs of rollers and cooling water sprinklers and between which the cast product A is guided along a casting line 10.

De façon connue la poutre 5 est articulée à sa partie inférieure, autour d'un pivot 53 perpendiculaire au plan de la figure, sur un appui 54 qui peut être constitué par exemple par la partie supérieure de la poutre supportant la deuxième partie du corset. A sa partie supérieure, la poutre 5 est guidée par un axe 55 coulissant lelong d'une glissière ménagée sur un appui fixe 40 et sensiblement parallèle à la ligne de coulée.In known manner the beam 5 is articulated at its lower part, around a pivot 53 perpendicular to the plane of the figure, on a support 54 which can be constituted for example by the upper part of the beam supporting the second part of the corset. At its upper part, the beam 5 is guided by an axis 55 sliding along a slide formed on a fixed support 40 and substantially parallel to the casting line.

Dans le mode de réalisation représenté, le levier d'oscillation 3 tourne autour d'un axe 30 dans un palier porté par un support 31 sur lequel est monté également le palier d'un second axe 32 autour duquel est articulé une bielle 33 articulée à son autre extrémité sur la table d'oscillation 2 de façon à assurer le maintien de celle-ci le long de la ligne de coulée lors des oscillations engendrées par le levier 3 qui est également articulé à son extrémité sur la table oscillante 2.In the embodiment shown, the oscillation lever 3 rotates around an axis 30 in a bearing carried by a support 31 on which is also mounted the bearing of a second axis 32 around which is articulated a connecting rod 33 articulated at its other end on the oscillation table 2 so as to maintain it along the casting line during the oscillations generated by the lever 3 which is also articulated at its end on the oscillating table 2.

Bien entendu, comme on le voit sur la figure 3, le levier et la bielle 33 sont constitués de deux bras placés symétriquement de part et d'autre du plan médian de la lingotière, latable oscillante 2 comportant deux prolongements inférieurs 21 sur lesquels sont articulés les extrémités des deux bras du levier 3.Of course, as can be seen in FIG. 3, the lever and the connecting rod 33 consist of two arms placed symmetrically on either side of the median plane of the ingot mold, oscillating latable 2 comprising two lower extensions 21 on which are articulated the ends of the two arms of the lever 3.

Selon l'invention, le support 31 des paliers du levier d'oscillation est monté ni sur le plancher de coulée 11 placé au niveau de la lingotière 1 ni à la partie supérieure de la poutre 5, mais au contraire est fixé directement sur une plateforme fixe 6 ménagée à la partie supérieure du massif de fondation 4 et se trouvant sensiblement au niveau supérieur de la poutre 5 de support du corset.According to the invention, the support 31 of the bearings of the oscillation lever is mounted neither on the casting floor 11 placed at the level of the ingot mold 1 nor at the upper part of the beam 5, but on the contrary is fixed directly on a platform fixed 6 formed at the upper part of the foundation solid 4 and located substantially at the upper level of the beam 5 for supporting the corset.

A cet effet, le massif de fondation 4 est prolongé vers le haut par une partie 41 qui peut monter jusqu'au niveau de la plateforme 6, mais on peut aussi, comme on l'a représenté sur la figure 1, ménager la plateforme 6 sur un châssis 60 en construction mécano-soudée massive, qui est fixé solidement sur le prolongement 41 du massif en béton. Etant donné sa forme simple et ses dimensions relativement réduites, le châssis 60 peut en effet être construit de façon très rigide et faciliter cependant la précision de positionnement des différentes parties de la machine et notamment des supports 31. D'autre part,le support 40 de la glissière 55 peut également être fixé sur le châssis 60, aussi près que possible de la partie en béton 41.To this end, the foundation block 4 is extended upwards by a part 41 which can rise up to the level of the platform 6, but it is also possible, as shown in FIG. 1, to provide the platform 6 on a chassis 60 in massive mechanically welded construction, which is firmly fixed on the extension 41 of the concrete block. Given its simple form and its relatively small dimensions, the frame 60 can indeed be built very rigidly and yet facilitate the positioning accuracy of the different parts of the machine and in particular of the supports 31. On the other hand, the support 40 of the slide 55 can also be fixed to the frame 60, as close as possible to the concrete part 41.

La partie supérieure du corset qui se trouve placé immédiatement au-dessous de la lingotière doit être réalisée de façon particulière car, à cet endroit, la croute solidifiée constituée dansla lingotière est encore très mince et les rouleaux d'appuis du produit doivent être assez rapprochés où même remplacés par des plaques de guidage. En outre, c'est à cet endroit que peuvent se produire des percées et il est donc utile de pouvoir remplacer cette partie du corset. C'est pourquoi, généralement, on place à cet endroit un segment particulier 56 qui assure l'alignement entre la sorte de la lingotière 1 et l'entrée dans le segment suivant 50-du corset de refroidissement. Pour assurer cet alignement, on a déjà proposé de suspendre le segment supérieur 56 sur des bras fixes en forme de fourche 62 par l'intermédiaire d'un axe 57 placé à sa partie inférieure, sa partie supérieure étant guidé directement par une glissière par rapport à la lingotière 1 ou à la table oscillante 2. Dans les modes de réalisation connus jusqu'à présent, les bras de support 62 étaient fixés sur une entretoise analogue aux entretoises 52 et reliant les extrémités supérieures des deux longerons 51 formant la poutre 5.The upper part of the corset which is placed immediately below the mold must be made in a special way because, at this point, the solidified crust formed in the mold is still very thin and the product support rollers must be close enough where even replaced by guide plates. In addition, this is where breakthroughs can occur and it is therefore useful to be able to replace this part of the corset. This is why, generally, a particular segment 56 is placed at this location which ensures alignment between the kind of the ingot mold 1 and the entry into the next segment 50 of the cooling corset. To ensure this alignment, it has already been proposed to suspend the upper segment 56 on fixed fork-shaped arms 62 by means of an axis 57 placed at its lower part, its upper part being guided directly by a slide relative to to the ingot mold 1 or to the oscillating table 2. In the embodiments known up to now, the support arms 62 were fixed on a spacer similar to the spacers 52 and connecting the upper ends of the two longitudinal members 51 forming the beam 5.

Selon l'invention, les bras 62 du support de l'élément supérieur du corset 56 sont fixés directement sur la plateforme fixe 6 du massif de fondation 4.According to the invention, the arms 62 of the support of the upper element of the corset 56 are fixed directly to the fixed platform 6 of the foundation block 4.

De la sorte, on assure un alignement parfait entre la lingotière et l'élément 56, ces deux organes étant portés par des bras fixés sur la même plateforme 6. L'alignement est également respecté entre l'élément 56 et le segment suivant 50 du corset puisque la glissière 40 de guidage du corset est également fixée sur le châssis 60 portant la plateforme 6.In this way, perfect alignment is ensured between the mold and the element 56, these two members being carried by arms fixed on the same platform 6. The alignment is also respected between the element 56 and the following segment 50 of the corset since the guide 40 for guiding the corset is also fixed to the chassis 60 carrying the platform 6.

Par ailleurs, le montage sur le même châssis rigide 60 de l'ensemble des organes essentiels de la machine facilite le réglage du positionnement relatif de ces organes et le maintien de l'alignement pendant la coulée.Furthermore, the assembly on the same rigid frame 60 of all the essential components of the machine facilitates the adjustment of the relative positioning of these components and the maintenance of the alignment during casting.

Grâce aux dispositions selon l'invention, les moyens d'oscillation et de guidage de la lingotière ainsi que les axes de support du corset sont donc fixés sur une masse lourde capable d'absorber les vibrations. En principe, l'isolation réciproque des lignes est réalisée de cette façon. Cependant, dans certains cas et par exemple lorsque la distanceentre les lignes est réduite, que les masses en mouvement sont importantes ou bien en raison de-risques particuliers dûs à la fréquence ou à l'amplitude du mouvement, il est possible d'améliorer l'isolation vibratoire par une étude particulière de la partie haute 41 du massif de fondation et par exemple, comme on l'a représenté sur la figure 3, en montant chaque ligne sur un massif de fondation individuel, les massifs voisins étant séparés par un espace vide 42 ménagé dans un plan vertical jusqu'à un niveau convenable vers le bas pour assurer l'isolement.Thanks to the arrangements according to the invention, the means of oscillation and guiding of the mold as well as the support axes of the corset are therefore fixed on a heavy mass capable of absorbing vibrations. In principle, the reciprocal isolation of the lines is carried out in this way. However, in certain cases and for example when the distance between the lines is reduced, that the masses in movement are important or because of particular risks due to the frequency or the amplitude of the movement, it is possible to improve the vibration isolation by a particular study of the upper part 41 of the foundation block and for example, as shown in FIG. 3, by mounting each line on an individual foundation block, the neighboring blocks being separated by an empty space 42 formed in a vertical plane to a suitable level down to ensure isolation.

Bien entendu, l'invention ne se limite pas aux détails du mode de réalisation qui vient d'être décrit, ni au type de machine de coulée continue qui n'a été retenu qu'à titre d'exemple. En particulier en modifiant la forme du massif de fondation et notamment de son prolongement 41 et du châssis - 60 supportant la plateforme 6, on pourrait adapter l'invention à d'autres types de machines et notamment à d'autres types de mécanismes d'oscillat-ion et de guidage de la lingotière.Of course, the invention is not limited to the details of the embodiment which has just been described, nor to the type of continuous casting machine which has been retained only by way of example. In particular by modifying the shape of the foundation mass and in particular of its extension 41 and of the chassis - 60 supporting the platform 6, the invention could be adapted to other types of machines and in particular to other types of mechanisms. oscillating and guiding the mold.
