The invention relates to a device for connecting a fluid circulating line (6) to a refractory element (1) having a wall provided with a cylindrical bore (5a, 5b), comprising a gasket (14) intended to be located into the bore and a first supporting element (13) compressing the gasket from the outside of the bore. A second supporting element (9b) which can be introduced into the bore sandwiches the gasket (14) together with the first supporting element (13) and a rod (9a) brings the two supporting elements closer so as to compress the gasket. The invention also relates to a refractory element (1), notably a nozzle or a pouring shroud, provided with a cylindrical bore (5) sized to receive two supporting elements (9b, 13) and a tightening gasket (14) sandwiched by these supporting elements.
La présente invention concerne un dispositif de connexion d'une conduite (6) de circulation de fluide vers un élément réfractaire (1) possédant une paroi pourvue d'un alésage cylindrique (5a, 5b), qui comprend un joint (14) destiné à être placé dans cet alésage et un premier élément de support (13) comprimant ce joint de l'extérieur de l'alésage. Un second élément de support (9b) qui peut être introduit dans l'alésage prend en sandwich le joint (14) avec le premier élément de support (13) et une tige (9a) rapproche les deux éléments de support de manière à comprimer le joint. Cette invention concerne aussi un élément réfractaire (1), notamment une buse ou un bec verseur, pourvu d'un alésage cylindrique (5) dimensionné pour recevoir deux éléments de support (9b, 13) et un joint de serrage (14) pris en sandwich entre ces éléments de support.
