The invention relates to a sliding gate device for a vessel containing a molten metal. It comprises a stationary body (18, 20) defining an internal chamber (26) with an upstream wall and a downstream wall, each of said walls being provided with an opening, and said openings being opposite one another, as well as a sliding gate (28) movably mounted in said chamber and provided with at least one through-hole between its main surfaces. The sliding gate is guided by said chamber and a clearance is provided between the main sliding gate surfaces (28a, 28b) and the inner chamber wall. First and second means (40, 42) are provided for generating gas pressure in said chamber to provide a sealing gas flow between said sliding gate surfaces and the upstream and downstream chamber walls, whereby metal seepage is prevented. The first means (40) move the sliding gate in a first direction and the second means (42) move the sliding gate in the opposite direction.
La présente invention vise une vanne à tiroir pour un récipient contenant du métal en fusion. La vanne en question est constituée d'un corps fixe (18, 20) renfermant une chambre interne (26) avec paroi amont et paroi aval, chacune desdites parois comportant un orifice disposé en opposition l'un par rapport à l'autre, et tiroir (28) mobile comportant au moins une lumière ménagée de part en part de ses principales surfaces. Le tiroir se déplace dans la chambre interne, un espace étant ménagé entre les principales surfaces du tiroir et les parois de la chambre, cet espace étant scellé par une lame de gaz produite par un premier et par un deuxième éléments (40,42) générateurs de pression de gaz et destinée à empêcher toute fuite de métal au tiroir. Le premier élément (40) déplace le tiroir dans un premier sens, et le deuxième élément (42) le déplace dans le sens opposé.
