Abstract Scope Intelligent control and digital technologies are now widely developed to improve the efficiency of aluminum production. The paper elaborates on how system is based on machine vision with training a neural network to determine the types of violations of the sealing of electrolyzers. Control commands of the system and operational analysis of their support can be used to improve or enhance the environment in a potroom. The use of machine vision and neural networks made it possible to reduce in half the time during which the cells are partly sealed, and to reduce AlF3 consumption by 3-5 kg/t Al. The in-house system was successfully tested in EcoSøderberg potrooms of Krasnoyarsk smelter. Plans are to deploy the system across all RUSAL’s smelters with Søderberg technology. Тext step of RUSAL Engineering & Technology Center is proceeded to develop a machine vision system to improve the environment in PB potrooms.
