| description | The invention relates to the field of monocrystalline smelting, and in particular to a monocrystalline smelting mould (1) including at least one moulding cavity (7), a starter cavity (10) having at least one first inverted funnel-shaped space (10a), and a separate second pedestal-shaped space (10b) at the bottom of the first volume and projecting substantially relative to said first space in at least one horizontal direction, as well as a selector channel (9) connecting said starter cavity (10) to said moulding cavity (7) and a supporting rod (20), offset laterally relative to said selector channel, and connecting the second space (10b) of the starter cavity (10) to the moulding cavity (7). The invention also relates to a smelting method using such a mould (1).
L'invention concerne le domaine de la fonderie monocristalline, et en particulier un moule (1) pour fonderie monocristalline comprenant au moins une cavité de moulage (7), une cavité de démarrage (10) avec au moins un premier volume (10a) en forme d'entonnoir inversé, et un deuxième volume (10b) distinct en forme de socle à la base du premier volume et sensiblement en saillie par rapport audit premier volume dans au moins une direction horizontale, ainsi qu'un canal sélecteur (9) reliant ladite cavité de démarrage (10) à ladite cavité de moulage (7) et une tige de soutien (20), latéralement décalée par rapport audit canal sélecteur, et reliant le deuxième volume (10b) de la cavité de démarrage (10) à la cavité de moulage (7). L'invention concerne aussi un procédé de fonderie utilisant un tel moule (1). |
