Abstract

Une méthode et un appareil sont fournis pour produire des flux discontinus d'une substance inorganique, tel qu'un métal, un alliage, un sel fondu, des scories ou une matte, ou encore une barbotine de particules céramiques, où la substance, se présentant sous forme de matériau fondu ou de barbotine, est maintenue dans un récipient au fond duquel se trouve au moins un bec contenant au moins une ouverture avec une épaisseur assez large pour supporter les tensions mécaniques et thermiques et le matériau fondu ou la barbotine est poussée à travers ces ouvertures au moyen d'un applicateur d'impulsions positionné sur les ouvertures et fonctionnant de manière périodique.
