Abstract

Procedimiento para la alimentación continua de cubas de electrólisis de al alúmina, por introducción de óxido de aluminio en el baño de la célula valiéndose de medios de impulsión mecánica, pro ejemplo mediante un alimentador impulsor del tipo de tornillo sin fin, a una presión capaz de romper la costra superficial de dicho baño, caracterizadas por el hecho de que el punto de introducción del óxido de aluminio en el baño se ajusta en altura así como en plano durante el curso de la electrólisis.Procedure for the continuous feeding of alumina electrolysis tanks, by introducing aluminum oxide into the cell bath using mechanical drive means, for example by means of an endless screw type driving feeder, at a pressure capable of breaking the surface crust of said bath, characterized in that the point of introduction of the aluminum oxide in the bath is adjusted in height as well as in plane during the course of electrolysis.
