Abstract

Le procédé selon l'invention consiste à préparer un modèle fusible 1 constituant la réplique de la pièce moulée à obtenir, éventuellement avec un noyau 3, la formation d'un revêtement du type caparace réfractaire 2 et la fusion partielle au moyen de la vapeur d'un solvant d'une partie de la surface du modèle pour obtenir un jeu faible 3a, et ensuite la fusion complète du modèle pour obtenir une carapace en une pièce ayant une cavité correspondant à la forme de la pièce à obtenir, cette carapace étant ensuite préchauffée à une température voisine de celle du métal en fusion devant être coulé pour obtenir la pièce moulée désirée. Le procédé selon l'invention convient en particulier pour former des hélices de navire en acier inoxydable.The method according to the invention consists in preparing a fusible model 1 constituting the replica of the molded part to be obtained, optionally with a core 3, the formation of a coating of the refractory caparace type 2 and the partial melting by means of the steam d 'a solvent of part of the surface of the model to obtain a low clearance 3a, and then the complete fusion of the model to obtain a shell in one piece having a cavity corresponding to the shape of the piece to be obtained, this shell then being preheated to a temperature close to that of the molten metal to be cast to obtain the desired molded part. The method according to the invention is particularly suitable for forming ship propellers made of stainless steel.
