Computer Simulation of High Temperature Corrosion Hazard of Anode Steel Stubs in Aluminium Electrolysis Cell

In the industrial production of primary aluminium process, the high temperature gaseous and the molten cryolite-alumina salt electrolyte will corrosion anode steel stubs. High temperature corrosion products of the stub are analyzed by SEM-EDX. Corrosion products consist of the mixed F, O, Na and Fe, etc. From computer simulation, high temperature corrosion of anode stubs will lead steel stubs current to inconsequence, cell voltage to high, anode consumption to inequality, etc. The current efficiency, current consumption and life of electrolysis cell will change to poor.
