Abstract

INSTALLATION DE PRODUCTION DE PLASMA COMPRENANT UNE ENCEINTE VERTICALE DANS LAQUELLE DEBOUCHENT DES ELECTRODES PRINCIPALES ET UN CHALUMEAU D'AMORCAGE D'ARC. CHAQUE ELECTRODE 12 COMPORTE UN TUBE DE GUIDAGE TERMINE PAR UN CONE DE GAINAGE DE GAZ RESISTANT AUX TEMPERATURES ELEVEES. L'ELECTRODE EST CONSTITUEE PAR UN CORPS BON CONDUCTEUR DE L'ELECTRICITE ET UNE POINTE QUI DELIMITE AVEC LE CONE UN ESPACE ANNULAIRE DE FAIBLE EPAISSEUR. APPLICATION A LA SPHEROIDISATION DES MATERIAUX.
