Abstract

Un método para producir un producto de hierro líquido y producto de hierro obtenido por el método, donde se opera un horno de reverbero giratorio (28)conjuntamente con un dispositivo de fusion eléctrica (34) para la produccion de un producto de hierro de alta pureza (36) que tiene un rango de silicio ymanganeso con bajo contenido de azufre y fosforo. El método incluye producir un producto de hierro de alta pureza y un rango de producto que contiene carbono(31) proveniente de productos compactosque contienen carbono y oxido de hierro (19), incluyendo las etapas de proveer un horno para reduccion directa de losproductos compactos que contienen carbono y oxido de hierro (19), pre-reduciendo los productos compactos que contiene hierro y carbono (19) en un horno quetiene una superficie de reverbero giratoria, produciendo hierro metalizado intermedio que contiene carbonos, Se utiliza un horno de fusion eléctrica (34) pararecibir hierro metalizado intermedio se contienen carbono desde la etapa de pre-reduccion, el cual es alimentado en forma directa y continua dentro de un áreainterior central del dispositivo de fusion eléctrica, con el calentamiento del hierro metalizado que contiene carbono en el dispositivo de fusion eléctricabajo elevadas temperaturas de alrededor de 1300sC hasta alrededor de 1700sC minimizando el ingreso de aire u otros gases indeseables tales como oxígeno en laetapa de fusion mientras se mantienen las elevadas temperaturas, y se remueve el producto de hierrolíquido de alta pureza desde el dispositivo de difusioneléctrica. El método provee un producto de alto contenido de hierro que tiene un rango especificado de porcentaje de manganeso, silicio y carbono, con bajocontenido de azufre y fosforo. Existe una significativa reduccion de oxidos de silicio y reduccion de oxidos de manganeso del producto. Se produce un productocon contenido alto de hierro, extremadamente deseable, para ser utilizado en la industria de obtencion de acero.
