Abstract

Un recipiente metalurgico (1) con un dispositivo de colada (5) para la extraccion controlada, libre de escoria de metal líquido (3), segun el principio delsifon para líquidos, de un bano de metal fundido que se encuentra en el recipiente (1),estando el recipiente conformado de modo que un primer brazo (11) de untubo de descarga (10), conformado en la forma de una U o V invertida, atraviesa la pared refractaria (15) del recipiente, y un borde de rebalse (14) que seencuentra en la zona deunion d e los dos brazos (11, 12) del tubo de descarga (10) se encuentra en una posicion más alta que el borde superior (18) de laabertura de entrada (17) del tubo de descarga. La masa fundida (3) en el tubo de descarga (10) preferentemente puedeser calenta da por induccion. Se relatatambién sobre un procedimiento para la extraccion de metal líquido que se encuentra sobre el recipiente y que consiste en: Después de un proceso de colada,cerrar la abertura de salida del tubo de descarga,elevar el nivel d el bano en el recipiente de fusion hasta una altura de colada y después cerrar una válvulade ventilacion que se encuentra en una bifurcacion de la zona de union de los dos brazos, iniciar el proceso de colada abriendo eldispositivo de cierre delsegu ndo brazo y descargando una cantidad residual del proceso de colada anterior que quedo en el segundo brazo y/o una cantidad de rebalse de la masa metálicafundida en la zona de union de los dos brazos, con lo cual esarrastrada masa metálica fundida a dicional que se encuentra en el primer brazo y en elrecipiente.A metallurgical container (1) with a casting device (5) for controlled extraction, free of liquid metal slag (3), according to the principle of the siphon for liquids, of a molten metal bath found in the container (1 ), the container being shaped so that a first arm (11) of a discharge pipe (10), formed in the form of an inverted U or V, crosses the refractory wall (15) of the container, and a leading edge ( 14) which is located in the junction zone of the two arms (11, 12) of the discharge tube (10) is in a position higher than the upper edge (18) of the inlet opening (17) of the discharge tube. The melt (3) in the discharge tube (10) can preferably be heated by induction. It is also related to a procedure for the extraction of liquid metal that is on the container and that consists of: After a casting process, close the outlet opening of the discharge tube, raise the level of the bath in the fusion vessel up to a casting height and then close a ventilation valve that is located at a fork in the junction zone of the two arms, start the casting process by opening the closing device of the second arm and discharging a residual amount of the previous casting process that I remain in the second arm and / or an amount of overflow of the molten metal mass in the junction zone of the two arms, thereby dragging molten metal mass into a dion that is found in the first arm and in the vessel.
