Abstract

Un método para fabricar un acero con bajo contenido de carbono de menos de 0.035% en peso, que incluye las etapas de preparar un calor de la composición de acero fundido en un horno para fabricar acero a una temperatura de colada como se desee para desulfurización en un VTD, abrir la colada en una cuchara en la composición de acero fundido con un nivel de oxígeno de entre aproximadamente 600 y 1120 ppm, que proporciona el compuesto que forma escoria en la cuchara para formar una cubierta de escoria sobre la composición de acero fundido en la cuchara, que transporta el acero fundido a un VTD, descarburizar la composición de acero fundido en el VTD al hacer un vacío de menos de 650 milibares, después de la descarburación, transportar el acero fundido a un LMF y desoxidar la composición de acero fundido, después de desoxidar, regresar al VTD a desulfurar y desgasificar la composición de acero fundido, y vaciar la composición de acero fundido para formar una acero con bajo contenido de carbono de menos de 0.035% en peso.
