Abstract
Un método para producir lingotes de acero estabilizados por efervescencia, que comprende colar un acero efervescente en una lingotera hasta que se llene la lingotera en una proporción del 80% al 95%, dejar efervescer el acero colado durante un periodo de ¿ a 15 minutos, volver a empezar a colar hasta llenar sustancialmente de lingotera, y añadir aluminio fundido durante dicha colada vuelta a comenzar, iniciándose dicha adición de aluminio fundido después recomenzar la colada y terminándose antes de completar la colada recomenzada, caracterizado porque se añade solamente suficiente aluminio fundido para que dé lugar a un contenido en aluminio disuelto en el núcleo del lingote de 0,002% a 0,008% y un contenido en oxígeno disuelto en el núcleo del lingote de 35 a 75 ppm.
