Abstract

METODO PARA ALARGAR LA VIDA DE REVESTIMIENTOS REFRACTARIOS. BASADO EN INTRODUCIR CAL DOLOMITICA, PARA FORMAR ESCORIAS, EN CANTIDAD SUPERIOR A LA REQUERIDA EN EL PROCESO, ASI COMO GAS INERTE EN LA MASA FUNDIDA PARA ORIGINAR UNA ACCION RECIPROCA INTENSA ENTRE LA ESCORIA Y LA MASA FUNDIDA. USADO EN LOS CONVERTIDORES DE LAS ACERIAS DEL TIPO L. D.
