Abstract

Metodo para obtener arrabio o productos de acero l¡quido en un reactor de fusion (1), particularmente un gasificador de fusion, donde se reducen al menos parcialmente materiales de insumo que contienen hierro y en caso necesario  ridos, en al menos un reactor de reduccion (R1, R2, R3, R4) por medio de un gas reductor. Segun la invencion, una primera porcion de los materiales de insumo al menos parcialmente reducidos se funden en el reactor de fusion (1) con aporte de portadores de carbono y gas que contiene ox¡geno con formacion simult nea del gas reductor. El gas reductor se conduce al reactor de reduccion (R1, R2, R3, R4) y despues de pasar por este, se descarga como gas de alto horno y una segunda porcion de los materiales de insumo al menos parcialmente reducidos se lleva a un reactor de reduccion de fusion (15) para reducirlos y fundirlos. Reivindicacion 24: Planta para obtener arrabio o productos de acero l¡quido de acuerdo con el metodo de una de las reivindicaciones 1 a 23 con un reactor de fusion (1), particularmente un gasificador de fusion y al menos un reactor de reduccion (R1, R2, R3, R4) para reducir insumos ferrosos y si fuera necesario  ridos por medio de un gas reductor que se forma en el reactor de fusion (1) con aporte de portadores de carbono, particularmente carbon y gas que contiene ox¡geno, caracterizada porque se preven al menos dos hileras de 2 a 6, particularmente 3 o 4 reactores de reduccion conectados en serie, donde cada hilera es seguida de un dispositivo de compactacion en caliente (12, 13), particularmente un dispositivo de briquetado en caliente.
