Title (EN) ROTOR
Abstract: front page image
(EN)A rotor stem forming part of a rotary valve assembly for use with apparatus for handling of molten material, especially metal, comprises a longitudinal body (21), formed from refractory materials by an isostatic pressing method, having one end (30, 40) adapted to receive a driving component, wherein said end contains, for attachment of an inert gas gas feed pipe (31, 41), a coupler (32, 42) which is co-pressed into the body during forming thereof by isostatic pressing and is formed of thin metal of from high strength ceramic material to allow direct fastening of the feed pipe by threaded connection or compression joint to a substantially solid rotor head.
(FR)Une tige de rotor faisant partie d'un ensemble de vanne rotative utilisée avec un appareil de manipulation de matière fondue, notamment du métal, comprend un corps longitudinal (21), réalisé à partir de matériaux réfractaires selon un procédé de pression isostatique, comportant une extrémité (30, 40) adaptée pour recevoir un élément d'entraînement. Ladite extrémité contient, afin de permettre le raccordement d'un tube (31, 41) d'alimentation en gaz inerte, un raccord (32, 42) co-pressé dans ledit corps pendant sa formation par pression isostatique, et fait de métal mince ou de matière céramique hautement résistante, afin de permettre la fixation directe dudit tube d'alimentation par connexion filetée ou raccordement par compression à une tête de rotor solide.
