description: The analysis of the technology of major repairs of electrolyzes was carried out. The main stages of repairs have been studied and described. The materials used in major repairs are considered. The technology used at the Kandalaksha aluminum plant was considered. The stages of repair, methods of quality control and time spent on operations are described. The materials and technologies used were described. The calculation of metal losses from the downtime of electrolyzes during major repairs was made. A method is proposed to reduce the time of overhaul of KAZA electrolyzes by using more productive equipment. An assessment of the advantages that will reduce the time for repairs has been made. It is shown that the proposed acceleration of capital repairs will allow to produce an additional more than 81 tons of raw aluminum per year.
