Abstract

METODO PARA MODIFICAR Y/O ESPUMAR ESCORIAS METALURGICAS MEDIANTE LA ADICION DE MAGNESITA. LA INVENCION SE REFIERE A LA ADICION DE MAGNESITA PARA ESPUMAR ESCORIAS METALURGICAS, EN RECIPIENTES REVESTIDOS AL MENOS EN ZONA DE ESCORIA CON MATERIAL REFRACTARIO BASICO PARA COLADAS METALURGICAS INTRODUCIENDOSE MAGNESITA NATURAL SELECCIONADA Y TRITURADA HASTA GRANOS DE UN TAMAÑO DE 0 A 15 MM (MGCO3) EN LA ESCORIA QUE SE VA FORMANDO. LA INTRODUCCION EN LA ESCORIA DE MGCO3 SE HACE EN UN HORNO O RECIPIENTES METALURGICOS SIMILARES, INSUFLADOS EN FORMA DE POLVO MEDIANTE TRANSPORTE NEUMATICO Y MEDIANTE UNA LANZA. SE CONSIGUE UNA RAPIDA VELOCIDAD DE DISOLUCION DE LA MGCO3 QUE SURGE EN LA ESCORIA, INFLUYENDO FAVORABLEMENTE EN LA REOLOGIA.
