Abstract

Apparatus comprises a set of refractory assemblies for transferring molten metal between an upstream and a downstream container vessel, and includes: (a) a tapping spout from the upstream container formed of a number of refractory components, each component having \-1 surface contacting and forming a mating surface with corresponding surface of an adjacent component; (b) a liquid metal flow regulator for controlling the flow of molten metal between the containers; and (c) a shroud channel formed between two of the components, and positioned around the tapping spout adjacent to one of the mating surfaces. The shroud channel includes an inlet for the introduction of a gas or fluid, and an outlet to allow the gas or fluid to escape from the plant. Also claimed is plant for transferring molten metal between two containers, using a set of refractory transfer assemblies, similar to that claimed above. A method of regulating the supply of an inert gas shroud to the above transfer assembly plant during the transfer of the metal is also claimed, the flow being injected into a shroud channel at a sufficiently high rate to allow excess gas to escape from the outlet irrespective of the flow rate of the gas drawn into the tapping spout.

Description

INSTALLATION DE TRANSFERT DE METAL LIQUIDE
PROCEDE DE MISE EN OEUVRE. ET REFRACTAIRES
La présente invention concerne une installation de transfert de métal liquide, d'un conteneur amont vers un conteneur aval comprenant: un conteneur amont ; un conteneur aval ; un trou de coulée dans le conteneur amont; un dispositif de régulation de l'écoulement pour réguler le flux de métal liquide à travers le trou de coulée ; une série d'éléments réfractaires disposés entre le conteneur amont et le conteneur aval dans le prolongement du trou de coulée et délimitant un chenal de coulée par lequel l'acier s'écoule du conteneur amont vers le conteneur aval, chaque élément réfractaire du chenal de coulée comportant au moins une surface formant un joint avec une surface correspondante d'un élément réfractaire adjacent ; un canal de protection entourant au moins partiellement le chenal de coulée au niveau d'au moins un joint entre éléments réfractaires.LIQUID METAL TRANSFER SYSTEM
IMPLEMENTATION PROCESS. AND REFRACTORIES
The present invention relates to an installation for transferring liquid metal from an upstream container to a downstream container comprising: an upstream container; a downstream container; a tap hole in the upstream container; a flow control device for controlling the flow of liquid metal through the tap hole; a series of refractory elements arranged between the upstream container and the downstream container in the extension of the taphole and delimiting a pouring channel through which the steel flows from the upstream container to the downstream container, each refractory element of the channel casting comprising at least one surface forming a joint with a corresponding surface of an adjacent refractory element; a protective channel at least partially surrounding the pouring channel at the level of at least one joint between refractory elements.

Dans une installation de ce type, le chenal de coulée est en dépression par rapport à l'atmosphère parce que la section la plus étroite (I'étranglement), se trouve à sa partie supérieure. Par suite de cette dépression, de l'air peut être aspiré dans le chenal de coulée si ce dernier n'est pas parfaitement étanche. Ceci n'est généralement pas le cas parce que les joints entre les différents éléments réfractaires qui forment le chenal de coulée ne sont pas parfaits. De l'air est donc aspiré, ce qui conduit à une dégradation de la qualité de l'acier. In an installation of this type, the flow channel is in depression compared to the atmosphere because the narrowest section (the constriction), is at its upper part. As a result of this vacuum, air can be drawn into the runner if the latter is not perfectly sealed. This is generally not the case because the joints between the various refractory elements which form the runner are not perfect. Air is therefore drawn in, which leads to a deterioration in the quality of the steel.

Afin de résoudre ce problème, il est connu de créer une surpression d'un gaz neutre autour du chenal de coulée, au niveau de chaque joint critique.In order to solve this problem, it is known to create an overpressure of a neutral gas around the runner, at each critical joint.

Selon une réalisation connue, on forme une rainure dans l'une au moins des surfaces de jonction réfractaires. Cette rainure est alimentée en gaz neutre sous pression. Selon une autre réalisation connue, on ménage une chambre fermée qui entoure le joint extérieur des surfaces de jonction, et on alimente la chambre en gaz en surpression.According to a known embodiment, a groove is formed in at least one of the refractory junction surfaces. This groove is supplied with neutral gas under pressure. According to another known embodiment, a closed chamber is formed which surrounds the outer seal of the junction surfaces, and the chamber is supplied with overpressure gas.

Ces dispositions connues permettent de remplacer l'aspiration d'air par une aspiration de gaz neutre, ce qui supprime le problème chimique lié au contact de l'acier liquide avec l'air. These known arrangements make it possible to replace the suction of air with a suction of neutral gas, which eliminates the chemical problem linked to the contact of the liquid steel with the air.

Cependant, ces solutions connues présentent plusieurs désavantages.However, these known solutions have several disadvantages.

L'introduction de gaz dans le chenal de coulée n'est pas supprimée. Elle est même augmentée parce que la rainure ou la chambre sont en surpression. Ceci est un inconvénient particulièrement dans le cas d'un transfert d'acier entre un répartiteur et un moule de coulée continue.The introduction of gas into the sprue is not suppressed. It is even increased because the groove or the chamber are overpressure. This is a drawback, particularly in the case of a transfer of steel between a distributor and a continuous casting mold.

Le gaz introduit dans le chenal de coulée aboutit dans le moule et y provoque des perturbations telles que des turbulences, un déplacement de la poudre de couverture, et le piégeage de cette poudre dans l'acier liquide : ces perturbations dégradent la qualité de l'acier produit.The gas introduced into the pouring channel ends up in the mold and causes disturbances there such as turbulence, displacement of the covering powder, and the trapping of this powder in the liquid steel: these disturbances degrade the quality of the steel produced.

De plus, de nombreux tubes présentent une section de sortie plus grande que leur section d'entrée pour réduire la vitesse de métal à son arrivée dans le moule. La présence d'une quantité de gaz trop importante dans le tube peut empêcher le fonctionnement correct de ce type de tube. En effet la dépression y devient insuffisante pour que le niveau du métal monte dans la busette. Ce dernier tombe donc en jet dans le moule.In addition, many tubes have an outlet section larger than their inlet section to reduce the speed of metal as it enters the mold. Having too much gas in the tube can prevent this type of tube from working properly. In fact, the vacuum there becomes insufficient for the level of the metal to rise in the nozzle. The latter therefore falls as a jet into the mold.

Le gaz neutre qui est utilisé est généralement de l'argon. Ceci implique un coût supplémentaire étant donné que la rainure ou la chambre de protection doivent être alimentées en permanence et que les fuites peuvent être importantes. Ceci est particulièrement vrai dans le cas des chambres extérieures, que l'on peut difficilement rendre étanches, et qui nécessitent un débit important de gaz pour y maintenir une surpression
La présente invention a précisément pour objet une installation de transfert de métal liquide qui résout ces inconvénients.The neutral gas that is used is usually argon. This involves an additional cost since the groove or the protective chamber must be continuously supplied and the leaks can be significant. This is particularly true in the case of exterior chambers, which can hardly be sealed, and which require a large flow of gas to maintain an overpressure therein.
The present invention specifically relates to a liquid metal transfer installation which overcomes these drawbacks.

Ce résultat est obtenu par le fait que l'installation comprend des moyens (28, 30) pour introduire un agent de colmatage dans le canal de protection afin de réaliser ou au moins d'améliorer une étanchéité à l'air du joint entre éléments réfractaires. This result is obtained by the fact that the installation comprises means (28, 30) for introducing a sealing agent into the protective channel in order to achieve or at least improve an air tightness of the joint between refractory elements .

L'invention concerne également un procédé de réalisation, ou au moins d'amélioration, de l'étanchéité à l'air du joint entre éléments réfractaires.The invention also relates to a process for producing, or at least improving, the air tightness of the joint between refractory elements.

Ce procédé est caractérisé en ce que l'on introduit un agent de colmatage dans le canal de protection.This process is characterized in that a sealing agent is introduced into the protection channel.

Procédé d'iniection ponctuelle.Point injection procedure.

Ce procédé sera plus particulièrement utilisé lorsque le circuit de protection ne peut être équipé d'une sortie.This process will be more particularly used when the protection circuit cannot be equipped with an output.

La figure montre à titre d'exemple le schéma d'une installation de régulation en pression. Une régulation en débit peut être réalisée de manière similaire.The figure shows as an example the diagram of a pressure regulation installation. Flow regulation can be carried out in a similar manner.

Le débit est mesuré en continu et correspond aux fuites puisque le circuit est fermé.The flow rate is measured continuously and corresponds to leaks since the circuit is closed.

Lorsque le débit dépasse une valeur acceptable on injecte une dose prédéterminée inférieure au volume du circuit de protection et on vérifie l'efficacité du bouchage par la réduction de la valeur du débit. When the flow rate exceeds an acceptable value, a predetermined dose is injected which is less than the volume of the protection circuit and the effectiveness of the plugging is verified by reducing the value of the flow rate.

Procédé d' injection semiòntinue
Il offre l'avantage d'être économique en gaz et en produit de jointoyage (agent de colmatage) et de permettre un contrôle de l'efficacité du procédé.Semi-continuous injection process
It offers the advantage of being economical in gas and in grouting product (clogging agent) and in allowing a control of the efficiency of the process.

La pression de sortie Ps au limiteur de débit est ajustée à une valeur prédéterminée (généralement 0.1 à 0.3 bars).The outlet pressure Ps at the flow limiter is adjusted to a predetermined value (generally 0.1 to 0.3 bars).

En régime normal l'injecteur de poudre est fermé ainsi que la vanne. Le débit Qo traversant le circuit est prédéterminé et ajusté à une valeur supérieure au débit de fuite acceptable.Under normal conditions the powder injector is closed as well as the valve. The flow Qo passing through the circuit is predetermined and adjusted to a value greater than the acceptable leakage flow.

La pression d'entrée Pe est égale ou légèrement inférieure Ps (pression de sortie).The inlet pressure Pe is equal to or slightly lower Ps (outlet pressure).

Lorsque le taux de fuite s'accroit en raison de l'usure des réfractaires ou d'un réaccouplement par exemple, la pression Pe décroît. Lorsque son écart avec Ps devient trop important, ce qui est déterminé par les valeurs de réglage, le procédé de jointoyage est enclenché.When the leakage rate increases due to the wear of the refractories or a re-coupling for example, the pressure Pe decreases. When its deviation from Ps becomes too large, which is determined by the setting values, the jointing process is started.

II est nécessaire d'apporter un débit supplémentaire Qi de gaz en ouvrant la vanne pour dépasser le flux des fuites et générer un flux complémentaire dans le circuit de sortie en vue de laver l'excédent de produit de jointoyage (agent de colmatage). L'injecteur est alors ouvert durant un temps prédéterminé (généralement inférieur à la minute) et une quantité de produit est envoyée dans le circuit. It is necessary to provide an additional flow Qi of gas by opening the valve to exceed the flow of leaks and generate an additional flow in the outlet circuit in order to wash off the excess of grouting product (sealing agent). The injector is then opened for a predetermined time (generally less than a minute) and a quantity of product is sent into the circuit.

Après fermeture de la vanne et de l'injecteur, la pression Pe doit être revenue à une valeur voisine de Ps si les fuites ont été obstruées. Dans le cas contraire, il faut renouveler l'opération.After closing the valve and the injector, the pressure Pe must return to a value close to Ps if the leaks have been blocked. Otherwise, the operation must be repeated.

Le procédé peut à l'évidence être entièrement automatisé, ce qui facilite la tâche des opérateurs. The process can obviously be fully automated, which makes it easier for operators.

Procédé d'injection continue II offre l'avantage d'une régulation très simple mais nécessite une consommation plus importante de gaz et de produit de jointoyage.Continuous injection process II offers the advantage of very simple regulation but requires greater consumption of gas and jointing product.

Le débit de gaz est prédéterminé et ajusté à une valeur supérieure au taux de fuite maximum de manière à ce qu'un excédent de flux de gaz traverse le circuit jusqu'au limiteur de pression et lavé l'excès de produit de jointoyage dans le circuit.The gas flow rate is predetermined and adjusted to a value greater than the maximum leak rate so that an excess of gas flow crosses the circuit up to the pressure limiter and washed off the excess sealant in the circuit .

La mesure de la pression d'entrée Pa doit être en permanence supérieure à la pression
Ps prédéterminée et ajustée par le régulateur de pression. The measurement of the inlet pressure Pa must be permanently higher than the pressure
Ps predetermined and adjusted by the pressure regulator.
