Abstract

L'INVENTION CONCERNE UN DISPOSITIF DE PULVERISATION ROTATIF POUR LA PRODUCTION DE POUDRES DE METAL, COMPORTANT UN ARBRE DE COMMANDE ET UN DISQUE FIXE A L'EXTREMITE SUPERIEURE DE L'ARBRE DE COMMANDE DESTINE A ETRE MIS EN ROTATION A VITESSE ELEVEE. LE DISQUE EST MUNI A SON COTE SUPERIEUR D'UNE BAGUE METALLIQUE MONTEE AUTOUR DE LA CIRCONFERENCE DU DISQUE ET S'ETENDANT JUSQU'AU-DESSUS DE LA SURFACE SUPERIEURE DU DISQUE. UN REVETEMENT CERAMIQUE EST APPLIQUE SUR LA SURFACE SUPERIEURE DU DISQUE ET CE REVETEMENT EST RETENU A SA CIRCONFERENCE PAR LA SURFACE INTERIEURE DE LA BAGUE. LORSQUE DU METAL EN FUSION EST VERSE SUR LE DISQUE EN ROTATION UN FOND DE METAL SOLIDIFIE SE FORME SUR LE REVETEMENT CERAMIQUE ET LA SURFACE SUPERIEURE DE LA BAGUE. APPLICATION POUR LA FABRICATION DE POUDRES DE METAL.
