Abstract

L’invention concerne un procédé pour le recyclage de poudres de métal ou d’alliages métalliques comprenant une étape d’enfournement de poudres de métal ou d’alliages métalliques dans un four (33) de fusion, une étape de fusion des poudres de métal ou d’alliages métalliques dans une chambre (31) de fusion du four (33) de fusion, et une étape de coulée d’un lingot (23) de métal ou d’alliages métalliques. Selon l’invention, les poudres de métal ou d’alliages métalliques sont enfermées dans un contenant (11) avant l’étape d’enfournement, ledit contenant (11) étant en métal pur constituant la poudre de métal ou en alliage constitué par l’élément majoritaire et un ou plusieurs éléments d’addition de ladite poudre quand la poudre est un alliage métallique. Figure pour l'abrégé : Figure 1The invention relates to a method for recycling metal powders or metal alloys comprising a step of charging metal powders or metal alloys into a melting furnace (33), a step of melting the metal powders or metal alloys in a melting chamber (31) of the melting furnace (33), and a step of casting an ingot (23) of metal or metal alloys. According to the invention, the powders of metal or metal alloys are enclosed in a container (11) before the loading step, said container (11) being made of pure metal constituting the metal powder or of an alloy constituted by the the majority element and one or more addition elements of said powder when the powder is a metal alloy.
