Abstract

Método de introducir un material pulverulento en un baño de metal fundido, que incluye aspirar el polvo desde un espacio cerrado de almacenaje, alimentado con un gas portador, y conducir la corriente resultante de gas cargado de polvo por debajo de la superficie de dicho baño, caracterizado porque la proporción a la cual el polvo es introducido en el baño metálico se varía con independencia de la proporción de flujo del gas suministrando a dicho chorro una presión de gas fija y ajustando la presión del gas en el espacio de almacenaje del polvo a un valor seleccionado inferior a la presión del gas suministrado a dicho chorro.
