APPLICATION OF MATHEMATICAL METHODS TO OPTIMIZE ALUMINIUM PRODUCTION IN PRE-BAKED ANODE CELLS A.V. Knizhnik, A.A. Kuzakov, B.I. Zelberg, V.V. Veselkov “SibVAMI” JSC, Sovetskaya St., 55 , Irkutsk, 664007, Russia Keywords: pre-baked anode cell, ANSYS, thermo-electric model, anode change sequence Abstract ОА-300М1 aluminum cell [1] were performed by “SibVAMI” JSC using the ANSYS Multiphysics software package. The The OA-300 cell as well as the aluminium production technology methods developed by the experts of “Kievsky Polytechnical in 300 kA cells were developed by “SibVAMI”. At present, Institute” [8] were used for the cell calculations. studies aimed at increasing current load in the cell are performed. 330 kA amperage has been reached and a possibility of further The calculation was made using macros – command files in amperage increase is studied. Mathematical modeling methods APDL (ANSYS Parametric Design Language) and FORTRAN, were used in order to study possibilities of current increase and having the code more than 12000 lines. A cell casing was built in forecast results. the CAD-system (Autodesk Inventor) and imported to ANSYS. All the other cell elements were built in ANSYS (/Prep7) The paper is dedicated to two of them: numerical modeling in the automatically. But at the same time the sizes of lining layers, ANSYS system and proper estimation coefficient to make up the cathode blocks, sidewall cathode bars, edges and anode were set anode change sequence. Numerical modeling of temperature parametrically.
