Relationship Between Technical and Economic Indicators, Metal Level and Interpole Distance in an Aluminum Electrolyser

Abstract

The article presents, in order of discussion, the mechanisms of the possible influence of the main technological parameters of the operation of electrolyzers for the production of aluminum - the metal level and the interpolar distance - on the technical and economic indicators of the process of electrolytic production of aluminu. The conclusions in the article are confirmed by practical measurements of process parameters in operating electrolyzers for aluminum production using statistical methods of data analysis and are in good agreement with literary sources. The negative impact of an increase in the height of the metal surface wave in the electrolyzer shaft due to a decrease in the metal level in the aluminum electrolyzer on the technical and economic indicators of the aluminum production process is shown. It is suggested that the technological violation "non-quenchable anode effect" is a consequence of the change in the electrolyte flow regime from laminar to turbulent. The theoretical inefficiency of the "slot" anode technology is shown, as well as the reason for the significant difference in the current output in electrolyzers with pre-baked and self-baking anodes.
