Abstract

Ajutage de coulée conçu pour prévenir le collage d'imperetés non métalliques à la sortie de l'ajutage par une injection de gaz. Il comporte l'ajutage proprement dit, une chambre annulaire creuse (3) pour l'injection d'un gaz formée dans la direction axiale de l'ajutage proprement dit et de petits trous réticulés (4) en une disposition annulaire pour le soufflage d'un gaz et en communication avec la chambre annulaire creuse (3), ces petits trous débouchant dans la sortie (5) de l'ajutage. Les petits trous réticulés (4) sont formés à partir de filaments organiques enroulés autour d'une portion de la paroi interne de l'ajutage et qui sont ensuite carbonisés, volatilisés ou contractés par chauffage.
