Abstract
Procedure for feeding with alumina from an igneous electrolysis cell; used for the preparation of aluminum, which allows a dosed and regularly distributed feeding on the surfaces of the electrolysis bath as well as the maintenance of a regular layer of alumina on the bath, a procedure according to which the crust covering the bath is already chopped Subsequently, the alumina is continuously poured over the pitted area, each operation of chopping and pouring of alumina being carried out simultaneously at two symmetrical points in relation to the longitudinal axial vertical plane of the tub, characterized in that, in a first step, the first pit is minced vat head according to sensibly regularly spaced points, then the alumina is continuously poured over this head; then, in a second stage, the crust is minced according to substantially regularly spaced points first along the longitudinal side of the bath in, then, according to the second head, finally, in a third stage, alumina is continuously poured over the pitted area during the second time, the discharge being carried out in relation to: flow of alumina on the surface of the swept bath, constant.
