Abstract

Conduit élévateur destiné à la coulée de métaux sous la pression d'un gaz et constitué par un tube composé de plusieurs parois concentriques et plongeant avec son extrémité inférieure dans un métal fondu, la zone médiane du tube située entre les deux parois communiquant avec l'air ambiant par l'intermédiaire d'au moins un trou. La zone médiane est constituée par un intervalle d'air 26 et les deux parois délimitant l'intervalle d'air sont en une matière réfractaire non métallique, perméable aux gaz ou devenant perméable aux gaz en cours d'utilisation et sont, au moins à l'extrémité inférieure du conduit élévateur 6, reliées entre elles de manière étanche au métal fondu. L'invention est applicable en particulier au moulage de métaux sous basse pression.Elevator duct intended for the casting of metals under the pressure of a gas and consisting of a tube composed of several concentric walls and immersed with its lower end in a molten metal, the middle zone of the tube located between the two walls communicating with the ambient air through at least one hole. The middle zone is formed by an air gap 26 and the two walls delimiting the air gap are made of a non-metallic refractory material which is permeable to gases or which becomes permeable to gases during use and are, at least to the lower end of the elevator duct 6, connected together in a sealed manner to the molten metal. The invention is particularly applicable to the molding of metals under low pressure.
