Abstract

UN PROCESO PARA LA PRODUCCION DE HIERRO DE MATERIALES EN BRUTO FERROSOS EN UN CONVERTIDOR QUE CONTIENE UN HIERRO INICIAL FUNDIDO DENTRO DEL CUAL AL MENOS LOS COMBUSTIBLES, GASES OXIGENADOS Y MATERIALES EN BRUTO FERROSOS SON INTRODUCIDOS DURANTE LA FASE DE PRODUCCION, LOS GASES DE REACCION SIENDO QUEMADOS DESPUES CON LOS GASES DE OXIDACION EN EL ESPACIO DE GAS DEL CONVERTIDOR SOBRE LA FUNDICION Y EL CALOR RESULTANTE TRANSFERIDO AL BAÑO DE HIERRO, Y UNA CANTIDAD PARCIAL DE HIERRO FUNDIDO SIENDO ATERRAJADO DESPUES DE LA FASE DE PRODUCCION Y UN SIGUIENTE RESTO DE FUNDICION DE HIERRO INICIAL EN EL CONVERTIDOR PARA LA SIGUIENTE FASE DE PRODUCCION, EN DONDE EL PESO DE LA FUNDICION DE HIERRO INICIAL ESTA ENTRE EL 10% Y EL 60%, BASADO EN EL PESO DE LA FUNDICION DE HIERRO PRESENTE EN EL CONVERTIDOR DESPUES DE LA FASE DE PRODUCCION Y ANTES DE QUE LA CANTIDAD PARCIAL SEA ATERRAJADA, Y LOS MATERIALES EN BRUTO FERROSOS SON ALIMENTADOS CONTINUAMENTE A LA FUNDICION DE HIERRO A TRAVES DEL ESPACIO DE GAS DELCONVERTIDOR DURANTE LA FASE DE PRODUCCION MIENTRAS AL MISMO TIEMPO LOS GASES OXIGENADOS QUE CONTIENEN NO MAS DEL 50% DE OXIGENO SON SOPLADOS CONTINUAMENTE A LA SUPERFICIE DE LA FUNDICION.
