摘要： The invention relates to a cooling method of a igneous electrolytic cell for aluminium production wherein heat transfer fluid droplets (or “divided heat transfer fluid”) are produced, preferentially in a confined volume in contact with a specified surface of at least one wall of the shell of the pot of the electrolytic cell, so as to induce the evaporation of all or part of said droplets by contact with said surface and remove the heat from said surface. The invention also relates to a cooling system capable of implementing the cooling method. The invention makes it possible to obtain a high cooling efficiency due to the latent heat of vaporisation of the heat transfer fluid.

摘要： This invention relates to a cathode element for use in a pot of an electrolytic cell intended for production of aluminum. The cathode element comprises a cathode block and a steel connection bar. The connection bar includes at least one metal insert, whose electrical conductivity is greater than the electrical conductivity of the said steel. The presence of an insert according to the invention can simultaneously result in a very large drop in the global cathode voltage and a very strong reduction in the current density at the head of the block.

摘要： The invention relates to a process for regulating the acidity of the electrolytic bath by recycling fluorinated effluents emitted by the Hall-Heroult electrolytic cells for the production of aluminum, in which said fluorinated effluents are collected, by the dry route, on the alumina. It comprises the following stages:a reference value for the fluorine/alumina weight ratio is fixed in connection with the alumina leaving the collecting apparatus,a continuous measurement takes place of the fluorine and alumina quantities entering the collecting apparatus,the alumina flow rate is regulated so as to maintain the F/Al.sub.2 O.sub.3 ratio at its reference value, generally fixed between 0.5 and 3%,fluorinated alumina is fed into a storage means with a predetermined capacity and equipped with a level measuring means,the electrolytic cells are supplied with the fluorinated alumina taken from the storage means andthe acidity of each cell is adjusted through the addition of aluminum fluoride and/or varying the power dissipated in the cell.
