description: The theme of the final qualification work: "Influence of the cryolite ratio of the electrolyte on the indicators of KAZ".Â The purpose of the work: based on the analysis of industrial data of the Kandalaksha aluminum smelter for 2006-2021, to identify patterns (absence of patterns) of the influence of the cryolite ratio of the electrolyte of operating electrolyzers on indicators (current output, specific power consumption, productivity, specific consumption of raw materials, purity of raw aluminum, frequency and duration of anode effects, cell voltage) KAZ for the above period.In the theoretical part of this work, a general description of production indicators is given, examples of their calculation are given, and statistical methods for their study are analyzed. In the calculation part of the work, an analysis was carried out that allows us to assert the existence or absence of a correlation between the studied indicators. The analytical part presents the results of the statistical study, assesses the adequacy of the conclusions based on the existing theory of the process of electrolytic production of aluminum, and gives possible recommendations for the current production.Â The work was carried out on the basis of industrial technological data of the Kandalaksha aluminum plant for 2006-2021.
