Description
La présente invention concerne un dispositif de refroidissement d'un métal pendant la coulée, en vue de la coulée de ce métal avec une surchauffe proche de 0 °C ou en phase pâteuse dans une lingotière de coulée continue suivant le préambule de la revendication 1.The present invention relates to a device for cooling a metal during casting, with a view to casting this metal with overheating close to 0 ° C or in the pasty phase in a continuous casting mold according to the preamble of
On connaît l'intérêt du procédé de coulée avec une surchauffe proche de 0 °C ou en phase pâteuse pour la coulée continue des métaux, en particulier de l'acier. Dans un tel procédé, l'acier est refroidi, entre le récipient de coulée et la lingotière de coulée continue, jusqu'à une température proche de la température du liquidus ou comprise dans l'intervalle de solidification de cet acier. On assure ainsi au moins l'élimination de la surchauffe de l'acier et éventuellement on provoque l'apparition, dans l'acier, d'une fraction solidifée dont l'importance dépend du refroidissement appliqué. Au moins où il pénètre dans la lingotière, l'acier présente ainsi un état qui permet d'obtenir des structures fines et homogènes et de réduire les ségrégations dans les produits coulés.We know the advantage of the casting process with overheating close to 0 ° C or in the pasty phase for the continuous casting of metals, in particular steel. In such a process, the steel is cooled, between the casting container and the continuous casting mold, to a temperature close to the liquidus temperature or included in the solidification interval of this steel. This ensures at least the elimination of overheating of the steel and possibly causes the appearance, in the steel, of a solidified fraction, the importance of which depends on the cooling applied. At least where it enters the mold, the steel thus presents a state which makes it possible to obtain fine and homogeneous structures and to reduce segregation in the cast products.
Un dispositif de coulée d'un métal avec une surchauffe proche de 0 °C ou en phase pâteuse est révélé notamment par le brevet LU-A-86.688 (EP-A-269180, sur lequel le préambule de la revendication 1 est basé). Ce dispositif comprend essentiellement un conduit vertical pourvu extérieurement de moyens de refroidissement et un organe répartiteur assurant la distribution du métal coulé sur la paroi intérieure de ce conduit vertical.A device for casting a metal with overheating close to 0 ° C or in the pasty phase is disclosed in particular by patent LU-A-86,688 (EP-A-269180, on which the preamble of
L'objet de la présente invention est de proposer un dispositif particulier permettant d'effectuer dans les meilleures conditions le refroidissement du métal pendant la coulée.The object of the present invention is to provide a particular device allowing the metal to be cooled under the best conditions during casting.
Conformément à la présente invention, un dispositif de refroidissement d'un métal pendant la coulée dans un conduit vertical, avec un organe de répartition du métal sur la paroi intérieure du conduit vertical situé sensiblement à l'entrée dudit conduit vertical, est caractérisé en ce qu'il comporte une chambre d'alimentation disposée autour dudit conduit vertical et ayant une paroi frontale épousant à distance la forme dudit conduit vertical, et une chambre d'évacuation disposée autour de ladite chambre d'alimentation et séparée de celle-ci par une paroi intermédiaire, ladite chambre d'évacuation étant délimitée à l'arrière par une paroi extérieure, en ce que ladite paroi frontale est percée d'une pluralité de passages dirigés vers ledit conduit vertical, en ce qu'une partie desdits passages débouchent dans ladite chambre d'alimentation, en ce que l'autre partie desdits passages sont raccordés à des tubes qui traversent ladite chambre d'alimentation et ladite paroi intermédiaire et qui débouchent dans ladite chambre d'évacuation, en ce que ladite chambre d'alimentation comporte des moyens d'alimentation en liquide de refroidissement et en ce que ladite chambre d'évacuation comporte des moyens d'évacuation du liquide de refroidissement.According to the present invention, a device for cooling a metal during casting in a vertical pipe, with a metal distribution member on the inner wall of the vertical pipe located substantially at the entrance of said vertical pipe, is characterized in that that it comprises a supply chamber disposed around said vertical duct and having a front wall which remotely follows the shape of said vertical duct, and a discharge chamber disposed around said supply chamber and separated from the latter by a intermediate wall, said discharge chamber being delimited at the rear by an external wall, in that said front wall is pierced with a plurality of passages directed towards said vertical duct, in that a portion of said passages open into said feed chamber, in that the other part of said passages are connected to tubes which pass through said feed chamber and said intermediate wall and which open into said discharge chamber, in that said supply chamber comprises means for supplying coolant and in that said discharge chamber comprises means for discharging coolant .
Selon une variante particulière du dispositif de l'invention, lesdits moyens d'alimentation en liquide de refroidissement comprennent une chambre de distribution disposée autour dudit conduit vertical et communiquant avec ladite chambre d'alimentation par une série de voies réparties, de préférence uniformément, autour dudit conduit vertical.According to a particular variant of the device of the invention, said means for supplying coolant comprise a distribution chamber disposed around said vertical duct and communicating with said supply chamber by a series of channels distributed, preferably uniformly, around of said vertical duct.
Dans une réalisation préférée, ladite chambre d'alimentation et ladite chambre de distribution présentent au moins une portion de paroi commune, à travers laquelle sont percées lesdites voies de communication.In a preferred embodiment, said supply chamber and said distribution chamber have at least one portion of common wall, through which said communication channels are pierced.
Selon une particularité intéressante, lesdits passages percés dans la paroi frontale de la chambre d'alimentation débouchent dans le volume compris entre ladite paroi frontale et ledit conduit vertical, suivant une direction perpendiculaire à la surface dudit conduit vertical.According to an interesting feature, said passages drilled in the front wall of the supply chamber open into the volume between said front wall and said vertical duct, in a direction perpendicular to the surface of said vertical duct.
D'autres particularités et d'autres avantages de la présente invention apparaîtront à la lecture de la description qui est donnée ci-dessous à titre d'exemple. Cette description porte sur une réalisation préférée du dispositif de l'invention, telle qu'elle est illustrée par les dessins annexés dans lesquels la

Ces deux figures sont des représentations schématiques, dans lesquelles on n'a volontairement reproduit que les éléments directement nécessaires à la compréhension de l'invention. Des éléments analogues ou identiques sont désignés par les mêmes repères numériques, et les directions de circulation du liquide de refroidissement sont indiquées par des flèches.These two figures are schematic representations, in which only the elements directly necessary for the understanding of the invention have been reproduced voluntarily. Similar or identical elements are designated by the same reference numerals, and the directions of circulation of the coolant are indicated by arrows.
On a représenté schématiquement, dans la figure 1, une installation pour la coulée d'acier en phase pâteuse, équipée d'un dispositif de refroidissement de l'acier conforme à l'invention. Une telle installation est à présent connue dans la technique et elle ne sera pas décrite en détail ici. On rappellera simplement qu'elle comporte une lingotière de coulée continue 1, une busette de coulée 2 équipant par exemple une poche de coulée, un conduit vertical 3, disposé en amont de la lingotière 1 et prolongé par un élément tubulaire 7; le conduit vertical 3 est précédé par un tronçon réfractaire 8, dans lequel est en outre disposé un plateau 6 supporté par trois bras et assurant la répartition du métal. Le conduit vertical 3 est pourvu extérieurement de moyens de refroidissement comportant une entrée 4 et une sortie 5 du liquide de refroidissement.Schematically shown in Figure 1, an installation for the casting of steel in the pasty phase, equipped with a steel cooling device according to the invention. Such an installation is now known in the art and it will not be described in detail here. It will simply be recalled that it comprises a
Le dispositif de refroidissement conforme à l'invention est illustré à plus grande échelle dans la figure 2. Il comprend une chambre d'alimentation 9 disposée autour du conduit vertical 3 et ayant une paroi frontale 10 épousant, à une distance "e", la forme du conduit vertical 3. La chambre d'alimentation 9 est à son tour entourée par une chambre d'évacuation 11 délimitée d'une part par une paroi intermédiaire 12 qui la sépare de la chambre d'alimentation 9 et d'autre part par une paroi extérieure 13. La distance "e" constitue la largeur radiale d'un volume annulaire 14 formé entre le conduit vertical 3 et la paroi frontale 10.The cooling device according to the invention is illustrated on a larger scale in FIG. 2. It comprises a
Une chambre de distribution 15, équipée d'une entrée 4 du liquide de refroidissement, est également disposée autour du conduit vertical 3. Cette chambre de distribution 15 communique avec la chambre d'alimentation 9 par des voies 16 percées dans une portion de paroi qui est commune à ces deux chambres 9 et 15. La chambre d'évacuation 11 est pourvue d'une sortie 5 du liquide de refroidissement.A
Les chambres d'alimentation 9 et d'évacuation 11 sont fermées, à leur partie inférieure, par des fonds individuels 17, 18 qui empêchent la mise en communication de ces deux chambres.The
La paroi frontale 10 est percée d'une pluralité de passages qui débouchent dans le volume annulaire 14, perpendiculairement à la surface du conduit vertical 3. Une partie de ces passages, repérés 19, débouchent par leur autre extrémité à l'intérieur de la chambre d'alimentation 9, qui est ainsi mise en communication avec le volume annulaire 14. Les autres passages sont raccordés à des tubes 20 qui traversent de façon étanche la chambre d'alimentation 9 et la paroi intermédiaire 12 et qui débouchent dans la chambre d'évacuation 11. La chambre d'évacuation 11 est ainsi mise directement en communication avec le volume annulaire 14.The
Le conduit vertical 3 est généralement cylindrique circulaire; dès lors, les chambres 9, 11 et 15 sont toriques, par raison de symétrie. De plus,les passages sont de préférence uniformément répartis dans la paroi frontale 10.The
Le dispositif de refroidissement conforme à l'invention fonctionne de la façon suivante.The cooling device according to the invention operates as follows.
Le jet d'acier en fusion 21, provenant d'une busette de coulée 2 (non représentée dans la figure 2), tombe sur le plateau répartiteur 6, d'où il s'écoule sur le tronçon réfractaire 8 puis en une couche mince 22 le long de la surface intérieure du conduit vertical 3 en cuivre.The jet of
Pendant qu'il parcourt le conduit vertical 3, l'acier 22 doit être refroidi jusqu'à atteindre l'état pâteux par formation d'une fraction solidifiée.While it travels through the
A cet effet, un liquide de refroidissement, qui est généralement l'eau, est introduit sous pression, par l'entrée 4, dans la chambre de distribution 15 d'où il gagne la chambre d'alimentation en franchissant les voies 16. Par les passages 19, le liquide de refroidissement pénètre dans le volume annulaire 14 où il circule le long du conduit vertical 3 avant d'être évacué par les tubes 20. Le liquide de refroidissement arrive ensuite dans la chambre d'évacuation 11 d'où il s'échappe par la sortie 5.For this purpose, a cooling liquid, which is generally water, is introduced under pressure, through the
Les jets de liquide de refroidissement sortant perpendiculairement des passages 19 et la faible longueur du trajet de ce liquide entre un passage injection 19 et des tubes de reprise 20 voisins assurent un écoulement turbulent du liquide de refroidissement dans le volume annulaire 14. Il en résulte une grande efficacité de refroidissement du conduit vertical 3 et de l'acier 22, pour un débit peu élevé de liquide de refroidissement.The jets of coolant coming out perpendicularly from the
Il va de soi que la circulation du liquide de refroidissement peut être assurée, partiellement ou entièrement, par une pompe aspirante raccordée à la sortie 5.It goes without saying that the circulation of the coolant can be ensured, partially or entirely, by a suction pump connected to the
Le dispositif de l'invention peut comporter des moyens pour modifier des caractéristiques géométriques telles que la largeur "e" du volume annulaire 14 ou le diamètre des passages 19, respectivement des tubes 20, en fonction des vitesses d'écoulement désirées dans chaque application particulière.The device of the invention may include means for modifying geometric characteristics such as the width "e" of the
Des moyens de réglage peuvent également être prévus pour modifier le débit de liquide de refroidissement en fonction du refroidissement à appliquer dans chaque cas particulier d'application.Adjustment means can also be provided to modify the flow rate of coolant as a function of the cooling to be applied in each particular case of application.
A titre d'exemple, on a coulé un acier à 0,8 %C avec un débit de 4,8 kg/s, au moyen d'un dispositif illustré dans la figure 1. La température de l'acier dans la busette était de 1510 degrés °C. L'acier a été coulé sur un plateau répartiteur en matériau réfractaire, puis le long de la paroi intérieure d'un conduit vertical 3 cylindrique en cuivre, d'une longueur de 350 mm et d'un diamètre de 220 mm. Le conduit 3 était refroidi par de l'eau introduite à la température ambiante et circulant avec un débit de 27 m³/h. La perte de charge dans le dispositif de refroidissement a été de 3,5 kg/cm² . On a atteint une densité de flux de refroidissement de 4,2 MW/m² , avec une élévation de la température de l'eau de 7 °C.For example, a 0.8% C steel was poured with a flow rate of 4.8 kg / s, by means of a device illustrated in FIG. 1. The temperature of the steel in the nozzle was from 1510 degrees ° C. The steel was poured onto a distributor plate made of refractory material, then along the inner wall of a vertical
Par comparaison, un refroidissement analogue dans un dispositif usuel par écoulement de l'eau en film laminaire a nécessité un débit d'eau de 60 m³/h, a rencontré une perte de charge de 12 kg/cm² et a conduit à une densité de flux de refroidissement de 3 MW/m² .By comparison, similar cooling in a conventional device by flow of water in laminar film required a water flow rate of 60 m³ / h, encountered a pressure drop of 12 kg / cm² and led to a density of 3 MW / m² cooling flow.
Le dispositif de l'invention permet donc d'assurer un refroidissement plus efficace avec une moindre quantité de liquide de refroidissement et sous une pression moins élevée que dans les dispositifs antérieurs.The device of the invention therefore makes it possible to ensure more efficient cooling with a smaller quantity of coolant and at a lower pressure than in the prior devices.
Ce dispositif peut d'ailleurs être réalisé en une seule pièce, ou être constitué de plusieurs éléments, indépendants ou non, disposés autour du conduit vertical, sans pour autant sortir du cadre de la présente invention.This device can also be made in one piece, or consist of several elements, independent or not, arranged around the vertical duct, without departing from the scope of the present invention.
Dans la description qui précède, on a présenté et illustré principalement un dispositif dans lequel le conduit vertical (3) est cylindrique circulaire. L'invention n'est cependant pas limitée à ce type de conduit vertical; en fait, elle s'étend également à un conduit qui présenterait une section de sortie supérieure à sa section d'entrée, ainsi qu'à un conduit dont la section ne serait pas circulaire mais qui serait par exemple ovale.In the foregoing description, a device is presented and illustrated mainly in which the vertical duct (3) is circular cylindrical. The invention is however not limited to this type of vertical duct; in fact, it also extends to a duct which would have an outlet section greater than its inlet section, as well as to a duct whose section would not be circular but which would for example be oval.
Par ailleurs, cette description se réfère particulièrement au refroidissement d'un conduit vertical précédant une lingotière de coulée continue. Il va de soi qu'il ne sortirait pas du cadre de l'invention d'utiliser un tel dispositif pour assurer le refroidissement de la lingotière de coulée continue proprement dite, ou de tout autre moule ou lingotière nécessitant un refroidissement.Furthermore, this description particularly refers to the cooling of a vertical duct preceding a continuous casting mold. It goes without saying that it would not be departing from the scope of the invention to use such a device for cooling the ingot mold itself, or any other mold or ingot mold requiring cooling.
