Abstract

Procedimiento y su correspondiente aparato para el tratamiento de metal fundido con un aditivo reactivo, que incluye una cámara de reacción y un cazo de colada, teniendo el cazo de colada un orificio de salida que comunica con la cámara de reacción para la introducción en la cámara del aditivo reactivo y del metal fundido, una cámara de expansión que comunica por medio de un canal con la cámara de reacción y que está provista de un orificio de salida para el metal fundido, caracterizado el aparato porque la superficie de la sección transversal del orificio de salida de la cámara de expansión es inferior a la superficie de la sección transversal del orificio de salida del cazo de colada de tal manera que el metal fundido fluya a través de la cámara de reacción a una velocidad que asegura que la cámara de reacción se llenará en un grado suficiente para cubrir cualquier aditivo reactivo contenido en ella.
