Abstract

L'INVENTION CONCERNE LA METALLURGIE. ELLE A POUR OBJET UN PROCEDE DE PREPARATION DE POUDRE POUR COULEE, EN PARTICULIER POUR COULEE D'ACIER, CONSTITUEE D'AU MOINS UN COMPOSANT DE POUDRE POUR COULEE ET DE PREFERENCE D'UN FONDANT, PRESENTE SOUS FORME DE CORPS CREUX SPHERIQUES FERMES, LE PRODUIT DE DEPART UTILISE ETANT UN MELANGE EN POUDRE FINE COMPRENANT DES CONSTITUANTS DE POUDRE POUR COULEE ET EVENTUELLEMENT UN FONDANT, CONSISTANT A METTRE EN SUSPENSION LE PRODUIT DE DEPART ET A LUI AJOUTER UN AGENT GONFLANT, A EXPANSER LE MELANGE DU PRODUIT DE DEPART ET DE L'AGENT GONFLANT, CARACTERISE PAR LE FAIT QU'APRES L'EXPANSION ON CALCINE LES CORPS CREUX. APPLICATION A L'OBTENTION D'UNE POUDRE DE COULEE SOUS FORME DE CORPS CREUX SPHERIQUES NE CONTENANT PAS D'HUMIDITE RESIDUELLE.THE INVENTION CONCERNS METALLURGY. ITS OBJECT A PROCESS FOR THE PREPARATION OF POWDER FOR CASTING, IN PARTICULAR FOR CASTING OF STEEL, CONSTITUTED OF AT LEAST ONE COMPONENT OF POWDER FOR CASTING AND PREFERENCE OF A FLUX, IN THE FORM OF CLOSED SPHERICAL HOLLOW BODIES, THE STARTING PRODUCT USED BEING A MIXTURE IN FINE POWDER COMPRISING POWDER CONSTITUENTS FOR CASTING AND POSSIBLY A FLUX, CONSISTING OF SUSPENSIONING THE STARTING PRODUCT AND ADDING TO IT AN INFLATANT AGENT, EXPANDING THE MIXTURE OF THE DEPENDENT 'INFLATING AGENT, CHARACTERIZED BY THE FACT THAT AFTER EXPANSION HOLLOW BODIES ARE CALCINATED. APPLICATION TO OBTAINING A CASTING POWDER IN THE FORM OF SPHERICAL HOLLOW BODIES CONTAINING NO RESIDUAL HUMIDITY.
