Abstract

LA PRESENTE INVENTION CONCERNE UNE COMPOSITION ABRASIVE AINSI QUE SON PROCEDE DE FABRICATION. CETTE COMPOSITION EST CONSTITUEE PAR UN MELANGE DE BAUXITE ET DE ZIRCONE QUI A ETE FONDU ET RAPIDEMENT SOLIDIFIE. ELLE CONTIENT ENVIRON 25 A ENVIRON 50 EN POIDS DE ZIRCONE, ENVIRON 49,2 A ENVIRON 74,2 EN POIDS D'ALUMINE ET ENVIRON 0,8 A ENVIRON 2,5 EN POIDS DE SILICE. LE PROCEDE DE PREPARATION COMPREND LA FUSION D'UN MELANGE DE BAUXITE ET DE ZIRCONE, LE REFROIDISSEMENT DU MELANGE FONDU POUR SOLIDIFIER LA COMPOSITION EN TROIS MINUTES, DE PREFERENCE EN UNE MINUTE, ET LA PULVERISATION DU MELANGE REFROIDI RESULTANT POUR FORMER DES PARTICULES ABRASIVES. L'INVENTION S'APPLIQUE NOTAMMENT A LA PRODUCTION DE MEULES ABRASIVES.THE PRESENT INVENTION CONCERNS AN ABRASIVE COMPOSITION AS WELL AS ITS MANUFACTURING PROCESS. THIS COMPOSITION IS CONSTITUTED BY A MIXTURE OF BAUXITE AND ZIRCONIA WHICH HAS BEEN MELTED AND QUICKLY SOLIDIFIED. IT CONTAINS ABOUT 25 TO ABOUT 50 BY WEIGHT OF ZIRCONIA, ABOUT 49.2 TO ABOUT 74.2 BY WEIGHT OF ALUMINA, AND ABOUT 0.8 TO ABOUT 2.5 BY WEIGHT OF SILICA. THE PREPARATION PROCESS INCLUDES MELTING A MIXTURE OF BAUXITE AND ZIRCONIA, COOLING THE MOLTEN MIXTURE TO SOLIDIFY THE COMPOSITION IN THREE MINUTES, PREFERABLY IN ONE MINUTE, AND SPRAYING THE RESULTING COOLED MIXTURE TO FORM PARTICULATE FORMULAS. THE INVENTION APPLIES IN PARTICULAR TO THE PRODUCTION OF ABRASIVE WHEELS.
