  • Patent number: 6354363
    Abstract: The invention concerns an ingot mould comprising in succession, in the direction for extracting the metallic product to be cast (7): a preheater (5) made of noncooled refractory material acting as reservoir for the melting metal to be cast and a standard cooled tubular metal element (6) for solidifying the metal. A slot (18) for injecting the shearing gas (for example Ar) is arranged between the preheater (5) and the metal clement (6) so as to emerge on the ingot mold internal periphery.
