Abstract

METODO Y APARATO PARA TRATAR METAL FUNDIDO Y LOGRAR LA ELIMINACION EFECTIVA DE INCLUSIONES NO DESEADAS COMO GASES, METALES ALCALINOS, SOLIDOS ARRASTRADOS Y SIMILARES. DICHO METODO COMPRENDE LA INTRODUCCION CONTINUA DE METAL FUNDIDO EN UN RECIPIENTE QUE FORMA UN CANAL O UNA SECCION EN CANAL, COMO EL CANAL EXISTENTE ENTRE UN HORNO DE FUNDICION Y UNA MAQUINA DE FUNDICION, PROPORCIONANDO AL MENOS UN DISPENSADOR DE GAS DESPLAZABLE MECANICAMENTE (11), SUMERGIDO EN DICHO METAL (15) EN EL RECIPIENTE; Y LA INTRODUCCION DE GAS EN EL METAL ADYACENTE A UN DISPERSADOR DE GAS (14), EN UNA PARTE DEL CANAL QUE FORMA UNA ZONA DE TRATAMIENTO, DE FORMA QUE EL GAS SE ESCINDE EN PEQUEÑAS BURBUJAS MEDIANTE EL DISPENSADOR DE GAS (11) Y SE DISPERSA A TRAVES DE LA ZONA DE TRATAMIENTO. EL CANAL O SECCION EN CANAL ES DE TAL FORMA QUE PRESENTA UNA SUSPENSION DE METAL DE MENOS DEL 50 %.
