Abstract
UN METODO PARA SEPARA INCLUSIONES DE UN METAL FUNDIDO.MEDIANTE LAS FASES DE: A) PONER EN CONTACTO EL METAL FUNDIDO CON UN MEDIO QUE RETENGA A LAS INCLUSIONES A LAS QUE NO MOJA EL METAL. EL MEDIO PUEDE SER LIQUIDO, TAL COMO UNA MEZCLA DE SALES FUNDIDAS, O SOLIDO TAL COMO UN FILTRO DE MATERIALES CERAMICOS A LOS QUE NO MOJE EL METAL, O UN LECHO DE GRANULOS, POR EJEMPLO DE ALUMINA TABULAR; Y B) HACER PASAR EL METAL FUNDIDO A TRAVES DE UN FILTRO DE MATERIAL AL QUE MOJE EL METAL, POR EJEMPLO, DE UN METAL DURO RETRACTARIO TAL COMO DE DIBORURO DE TITANIO. EL FILTRO AL QUE MOJA EL METAL ATRAE Y RETIENE DENTRO DEL MISMO LAS INCLUSIONES A LAS QUE MOJA EL METAL, Y PUEDE TAMBIEN IMPEDIR, POR TENSION SUPERFICIAL, LA ENTRADA DE GOTITAS DE SALES FUNDIDAS.APLICADO EN EL TRATAMIENTO DE METALES, EN PARTICULAR DEL ALUMINIO Y SUS ALEACIONES.
