Procedure for precise Regulation of the rate of Introduction and the Alumina content of Cuba for the production of aluminium

摘要

Procedure to regulate the precise rate of Alumina content and the introduction of a VAT of Igneous Electrolysis, for the production of Aluminium according to the procedure heroalt Hall.It consists in introducing the alumina in the Molten Cryolite Bath directly through a Hole in the crust coagulated remained open, and in modulating the rate of introduction of Alumina based on the variations of the internal Resistance of Cuba, during Time intervals of PR Edeterminados,Alternating Cycles of equal Length for the introduction of Alumina slower Cadence and rhythm quickly, the rate that corresponds to the consumption of Cuba.
