Abstract

En un método para la producción de metal fundido, se introducen oxígeno, un agente reductor y hierro reducido en un reactor de reducción, dentro de un gasificador (3) de fundido, el agente reductor se gasifica con oxígeno y el hierro reducido se funde por medio del calor que se produce, el gas de cúpula se utiliza como por lo menos una fracción del gas de reducción. El gas superior que ha reaccionado se extrae del reactor (1) de reducción. Para una eficiencia aumentada en términos de energía y materias primas, en este caso se suministra por lo menos parte de la energía calorífica del gas superior y/o de la fracción del gas de reducción la cual se proporciona para uso como gas de enfriamiento y un gas en exceso que se va a utilizar para el calentamiento indirecto de por lo menos un gas adicional se utiliza en el método. Para este propósito, por lo menos un intercambiador de calor (15, 18, 21) en una línea (9 y/o 23) para gas superior y/o la fracción del gas de reducción la cual se proporciona para uso como gas de enfriamiento y como gas en exceso se proporciona, por lo menos un gas adicional utilizado en el método fluye a través del intercambiador de calor (15, 18, 21).
