Abstract

EN CE QUI CONCERNE LES PIECES REFRACTAIRES D'USURE DANS LES FERMETURES A COULISSE, LA PLAQUE COULISSANTE REFRACTAIRE EST MUNIE D'UNE BUSETTE REFRACTAIRE REMPLACABLE, QUI PORTE, SELON LA DEMANDE DE BREVET PRINCIPAL, UN INSERT USABLE REMPLACABLE POUR LA PLAQUE COULISSANTE. GRACE A L'UTILISATION AVANTAGEUSE D'INSERTS EN MAGNESIE POUR DES PLAQUES COULISSANTES EN OXYDE DE ZIRCONIUM OU EN ALUMINE, LA LONGEVITE DES PLAQUES EST AUGMENTEE.WITH REGARD TO WEAR REFRACTORY PARTS IN SLIDING CLOSURES, THE REFRACTORY SLIDING PLATE IS PROVIDED WITH A REPLACEABLE REFRACTORY NOZZLE, WHICH CARRIES, ACCORDING TO THE MAIN PATENT REQUEST, A REPLACABLE USABLE INSERT FOR THE SLIDING PLATE. THANKS TO THE ADVANTAGEOUS USE OF MAGNESIA INSERTS FOR SLIDING PLATES OF ZIRCONIUM OXIDE OR ALUMINA, THE LONGEVITY OF THE PLATES IS INCREASED.

Description

- La présente invention concerne un perfectionnement de la demande de- The present invention relates to an improvement in the application for

brevet n 8513990, déposée le 20 septembre 1985 et concernant une  Patent No. 8513990, filed September 20, 1985 and relating to a

fermeture à coulisse pour la buse de coulée de récipients métallurgi-  sliding closure for the pouring nozzle of metallurgical vessels

ques, présentant: une plaque coulissante réfractaire montée dans un cadre déplaçable par pivotement, rotation ou translation; un insert  ques, having: a refractory sliding plate mounted in a frame movable by pivoting, rotation or translation; an insert

usable disposé dans l'ouverture de passage; et une busette réfractai-  usable arranged in the passage opening; and a refractory nozzle

re remplaçable agencée derrière cet insert et portée par une monture pouvant être couplée au cadre déplaçable ou à une enveloppe en tôle de la plaque coulissante. Pour une fermeture à coulisse de ce type, l'invention de la demande de brevet principal consiste en ce que l'insert usable de la plaque coulissante réfractaire est conjugué à  replaceable arranged behind this insert and carried by a mount that can be coupled to the movable frame or to a sheet metal casing of the sliding plate. For a sliding closure of this type, the invention of the main patent application consists in that the usable insert of the refractory sliding plate is combined with

la busette réfractaire remplaçable, et peut être remplacé avec celle-  the replaceable refractory nozzle, and can be replaced with it

ci. Le but de la présente invention consiste, grâce à l'utilisation de matériaux réfractaires déterminés pour l'insert usable et pour la  this. The object of the present invention consists, thanks to the use of refractory materials determined for the usable insert and for the

busette remplaçable en harmonie avec le matériau de la plaque coulis-  replaceable nozzle in harmony with the material of the sliding plate

sante, à améliorer leur longévité.  health, to improve their longevity.

Selon l'invention, on atteint cet objet en utilisant un insert usable en magnésie (MgO) lorsque la plaque coulissante est en oxyde de zirconium (ZrO2) ou en alumine (A1203). Ainsi, on arrive, pour des plaques en oxyde de zirconium ou en alumine, qui, dans la zone de passage, s'usent prématurément par rapport aux surfaces de glissement, en raison de l'élargissement relativement rapide de l'ouverture de passage, à un niveau d'usure égalisé qui assure une usure optimale du  According to the invention, this object is achieved by using a usable insert in magnesia (MgO) when the sliding plate is made of zirconium oxide (ZrO2) or of alumina (A1203). Thus, we arrive, for zirconium oxide or alumina plates, which, in the passage area, wear out prematurely relative to the sliding surfaces, due to the relatively rapid widening of the passage opening, at an equalized level of wear which ensures optimal wear of the

matériau des plaques.plate material.

En outre, considérant la proposition de la demande de brevet principal, selon laquelle l'insert usable réfractaire et la busette réfractaire remplaçable peuvent être en des matériaux identiques ou différents selon le programme de coulée ou le type d'acier, il est également avantageux de fabriquer la busette réfractaire remplaçable entièrement en magnésie, et de l'insérer dans la plaque coulissante, constituée d'oxyde de zirconium ou d'alumine, de façon que leurs  In addition, considering the proposal of the main patent application, according to which the usable refractory insert and the replaceable refractory nozzle may be made of identical or different materials depending on the casting program or the type of steel, it is also advantageous to fabricate the replaceable refractory nozzle entirely in magnesia, and insert it into the sliding plate, made of zirconium oxide or alumina, so that their

surfaces de glissement soient planes et dans le même plan.  sliding surfaces are flat and in the same plane.
