Abstract
En un método para producir un acero fundido de acuerdo con un aspecto de la presente invención, el hierro de reducción directa en estado sólido contiene 3.0 % en masa o más de SiO2 y Al2O3 en total y 1.0 % en masa o más de carbono. Una proporción de un hierro metálico con respecto al contenido de hierro total contenido en el hierro de reducción directa en estado sólido es de 90 % en masa o más, y un exceso de contenido de carbono Cx de 0.2 % en masa o más con respecto a los carbonos contenidos en el hierro de reducción directa en estado sólido. El método incluye un paso de fusión en un primer horno de 40 a 100 % en masa del hierro de reducción directa en estado sólido, y separación de un arrabio líquido que tiene un contenido de carbono de 2.0 a 5.0 % en masa y una temperatura de 1350 a 1550 °C y una escoria que tiene una basicidad de 1.0 a 1.4 y un paso de fusión en un segundo horno de un remanente del hierro de reducción directa en estado sólido junto con el arrabio líquido separado en el primer horno y soplado de oxígeno sobre el material fundido para descarburarlo en un acero fundido.
