Abstract

Inventia se refera la un procedeu si la un dispozitiv pentru reglarea precisa a cadentei de introducere si a continutului în alumina a unei cuve destinate obtinerii aluminiului prin electroliza aluminei dizolvate într-o baie pe baza de criolita, a carei parte superioara formeaza o crusta solida si al carei continut de alumina trebuie sa fie mentinut într-un interval îngust, ales între 1 si 3,5%, procedeu în conformitate cu care se introduce alumina direct în baia de criolit topit, prin cel putin un orificiu mentinut deschis în crusta solidificata si se moduleaza cadenta de introducere a aluminei în functie de variatiile rezistentei interne ale cuvei în timpul unor intervale de timp predeterminate, alternînd ciclurile de introducere a aluminei cu cadenta mai lenta si cu cadenta mai rapida decît cadenta, astfel corespunzînd consumului normal al cuvei.
