Abstract

PROCEDIMIENTO PARA TRATAR CON MAGNESIO UNA MASA METALICA FUNDIDA, ESPECIALMENTE DE HIERRO. COMPRENDE REGULAR LA REACCION DE TRATAMIENTO CON MAGNESIO A UNA PROFUNDIDAD DE AL MENOS200 MM BAJO LA SUPERFICIE DE LA MASA FUNDIDA DE TAL MANERA QUE LA CANTIDAD DE MAGNESIO EVAPORADO GENERE UNA ENERGIA DE MEZCLA DE, COMO MINIMO, 1.000 W/MBS3, PREVIENDOSE EN EL RECIPIENTE DE TRATAMIENTO, SOBRE LA SUPERFICIE DE LA MASA FUNDIDA, UNA ATMOSFERA NO OXIDANTE. EL INVENTO ES UTIL PARA PRODUCIR UNA MASA FUNDIDA METALICA TRATADA CON MAGNESIO QUE CONTENGA MENOS DE 100 GRAMOS DE INCLUSIONES NO METALICAS POR TONELADA DE MASA FUNDIDA.
