The problem of increase of energy performances for higher amperage aluminum pots is discussed during magnet dynamic instability at anode effect. The concept of aluminum production without anode effects which is connected with monitoring of key parameters and discrete alumina feeding is offered.
The problem of increase of overall performance of powerful aluminum reduction pots at indemnification of metal losses is discussed during of magnet-dynamic movements. The scheme of asymmetric busbar is developed for increase of electrolysis productivity at the expense of MGD-stability.
The studies carried out over the last decades show that one of the main causes of failure of electrolyzers is the behavior of sodium in the process of aluminum electrolysis and its introduction into the electrolyzer bed. The paper describes the behavior of sodium in the process of aluminum electrolysis with the use of a number of additives in the electrolyte, which have some influence on the electrolysis process and the state of the electrolysis bath.
