Abstract

PROCEDIMIENTO PARA EL TRATAMIENTO DE MASAS FUNDIDAS DE HIERRO COLADO EN UNA CUCHARA ABIERTA MEDIANTE MAGNESIO PURO, INCORPORANDOSE EL MAGNESIO PURO EN LA MASA FUNDIDA DE HIERRO COLADO EN UNA PLURALIDAD DE PARTICULAS DE MAGNESIO MUY PEQUEÑAS, REVESTIDAS CON UNA CAPA PROTECTORA. LA CAPA PROTECTORA QUE PROTEGE EL MAGNESIO ANTE UNA FUSION PREMATURA Y QUE CONTROLA LA VELOCIDAD DE REACCION SE PRODUCE A PARTIR DE CERAMICA. LA REALIZACION DEL PROCEDIMIENTO ES POSIBLE CON DISPOSITIVOS MUY SENCILLOS. SE RENUNCIA A COSTOSOS TRATAMIENTOS PREVIOS DEL AGENTE DE TRATAMIENTO.
