Abstract

PROCEDIMIENTO PARA COLAR HIERRO TRATADO CON MAGNESIO, MEDIANTE UN APARATO DE COLADA ACCIONADO POR GAS A PRESION. SE CARACTERIZA PORQUE EL GAS INERTE QUE RETORNA TEMPORALMENTE DEL HORNO DE COLADA (25) ES CONDUCIDO SOLO A TRAVES DE UNA PARTE LIMITADA DEL SISTEMA DE CONDUCCION; PORQUE EL MAGNESIO QUE SE SEPARA POR CONDENSACION EN ESTE SISTEMA DE CONDUCCION, ES OXIDADO PERIODICAMENTE SIN INTERRUPCION DEL PROCESO DE COLADA; Y PORQUE LA OXIDACION SE REALIZA MEDIANTE UN GAS OXIDANTE INTRODUCIDO EN EL SISTEMA DE CONDUCCION, PREFERENTEMENTE MEDIANTE AIRE, ESTANDO BLOQUEADO DURANTE LA INTRODUCCION EL ESPACIO INTERNO DEL HORNO DE COLADA CON RELACION A LA PARTE DEL SISTEMA DE CONDUCCION.
