• Extract from the Reference on the chemical treatment of non-magnetic plate in the electromagnetic stirrer, Furnace No 9. RUSAL Sayanogorsk, JSC, 2017

    Before the washing, all the 7 channels of nonmagnetic plate in the electromagnetic stirrer showed uneven water flow and admixture of deposits ... All the channels were cleaned after 6 hours washing... After the return of the stirrer into operation on completion of the maintenance, the water supply system of the plate was restored. The water flow was stable and even in all 7 channels... Recurrent washing of nonmagnetic plates in electromagnetic stirrer ensures the increase in their service life and reliable flawless operation subject to the low quality of circulating water. Read...

  • Test Certificate of dust sheet heat insulating mat in Casthouse No 1, Casting Unit PNG-2 issued on 26.04.2018, RUSAL Sayanogorsk, JSC. Project of 2017
    This design is resistant to mechanical damage and almost completely excludes insulation fibers and shell fragments impurities in the melt. Three months of operation proved that there are no traces of the shell, mesh or internal insulating filler destruction. Mats tightly adhere to upper clamping plates of the metal track. Read...

  • Extract from the Certificate on completion of tests for the Mobile rectifier for manual arc welding VDU-1602Т in the existing Reduction Area of RUSAL Krasnoyarsk, JSC, issued on 23.07.2018
    On introduction of improvements, the test object "Mobile rectifier for manual arc welding VDU-2500" manufactured by Rezonans, LLC, passed the test according to the "Acceptance testing programs and techniques"... The Commission allows Mobile rectifier for manual arc welding VDU-2500 to be used under the conditions of the existing Reduction Area of RUSAL Krasnoyarsk, JSC. Read...
  • Extract from the Reference on the Electromagnetic Stirrer of Melt LIM-500 for Furnace No 8, Casthouse No 3. RUSAL Krasnoyarsk, JSC, Project of 2015
    It was the first experience within RUSAL group to install the frequency drive based on IGBT transistors to supply power to the inductor. No breakdowns were detected in the whole period of operation of power transistor modules... Unlike the electromagnetic stirrer previously installed on Furnace No. 8, the stirrer manufactured by Rezonans, LLC, generates no strong vibrations on the surface of the melt. Thus, the oxide film on the surface remains undamaged, and mixing progresses in the normal mode... Operation of the complex proved automation resistance to nonlinear distortions of the plant networks, efficiency and ruggedness of the cooling system, as well as a good maintainability and durability of electromechanical parts. Read...
  • Extract from the Reference on the supply of two sets of twinned aluminium filtration units UFP - 15 (УФП -15). RUSAL Bratsk, PJSC in Shelekhov, 2017
    Practice has shown that preliminary heating ensures faultless start of casting and ceramic foam filter filtration throughout the whole area. Specifically, it is worth noting the simple and efficient heating system that enables to protect heating elements from excessive heat exposure and their further breakdown. The service life of heating elements increases considerably... In the course of operation, the covers' design proved to be convenient, balanced, and good serviceability. The steady-state compressed air cooling system has high reliability to minimize the human factor. Solutions of the kind can be duplicated to heat filters and chutes in other units. Read...
