The researches – metallurgists of SFU became a part of the project aimed at development of technology to produce aluminum (RA-500) with reduced power consumption which won a mega-grant of the Ministry of Science and Education of the Russian Federation.
The amount of payment for a 3-year period will make 170 million rubles. Under the terms of the grant UC RUSAL will invest similar amount of funds. The allocated funds aim at facilitation research and development and in the field.
Such electrolyzers operating at 550 kA have been designed and successfully operating in Canada, UAE and China, for instance. The current UC RUSAL production facilities are operating at 450 кА. Thus, developing a revolutionary high-performance technology will favour both production upgrading and import-substituting technology development”, — said professor Pyotr Poliakov, project manager, Doctor of Chemistry.

The project group includes researches from School of Non-ferrous Metals and Material Science (SFU), Irkutsk National Research Technical University in close collaboration with Engineering Technology Center RUSAL aimed at developing cutting edge RA-500 technology. The challenge is to create a tailor-made aluminum technology that will meet the urgent requirements of US RUSAL production and come up with eco-friendly engineering solution facilitating higher plant performance, cost reduction and diminishing energy consumption.
“A stumbling block for a widespread promotion of modern high - performance electrolyte pots is mostly due to a short history of such technologies in Russian”, — said Vladimir Baranov, Director of the of Non-ferrous Metals and Material Science (SFU). — Today, the development is encumbered by deformation at the anode bottom and limited life time of cathodes, m.h.d melt instability and high energy dissipative process. The engineering solution of this challenges allow us to design a high-performance pot more energy efficient v.s its closest prior art” — he added.

The expected operation on the project is 3 year with the pilot site for the RA-500 project at the pilot base of Sayansky smelter, where during 1985-1995 initial research and development had been carried out and first high — performance pots (VAMI) were tested. Now, its own design booster pots RA-400 and RA-400T testing is in progress.
