Abstract

PROCEDIMIENTO PARA PRODUCIR LINGOTES DE ACERO EN UN ALTO HORNO CONVENCIONAL. EL ALTO HORNO SE CARGA CON UNA MEZCLA DE COQUE, HIERRO MINERAL E HIERRO MINERAL PRERREDUCIDO, CON UNA METALIZACION DEL 75 AL 90 POR 100 Y UN CONTENIDO EN CARBON, EN FORMA DE CARBURO FERRICO, DEL 1,4 AL 4,5 POR 100 EN PESO. UNA ALTERNATIVA CONSISTE EN CARGAR EL ALTO HORNO CON UNA CARGA QUE CONTIENE EL 60 POR 100 EN PESO DE POLVO DE CANALES DE GASES, DEL 5 AL 35 POR 100 DE MINERAL DE GRUMOS, Y DE 5 AL 35 POR 100 DE ESPONJA DE HIERRO, DE FORMA QUE UNA PORCION DE LA CARGA SE REDUCE CON CO, PRODUCIDO EN EL CRISOL Y EN EL ETALAJE DEL HORNO, Y CUALQUIER OXIDO DE HIERRO RESIDUAL QUE HAYA EN LA ESPONJA SE REDUCE POR EL CARBURO FERRICO PRESENTE EN ELLA.
