Abstract

Abstract: Finite element equations to calculate current and temperature fields of aluminum reduction cells are deduced using Galerkin method.The finite element model of anode and molten electrolyte is built according to multiple elements and multiple properties of ANSYS software.With reasonable assumption of boundary conditions,the current and temperature fields of 160?KA prebaked reduction cells are computed and the temperature,voltage and electric current distributions of the cells are analyzed.The simulation results of the model well coincide with the design data,and therefore provide foundations for optimizing current aluminum electrolysis cells and developing new type cells.

Key words: electrolysis cell, current field, temperature field, finite element, ANSYS
