Abstract Scope |
The heat balance of an Aluminum Electrolysis Cell (AEC) represents a very sensitive aspect of its operation. Steady state heat balance is quite well understood thanks to industrial expertise and widely used steady state finite elements models. With the increasing interest of power modulation, these tools become insufficient to predict the time dependent heat balance of the cell. Above all, they are not suited to predict the melting or formation of the side ledge, a protective solid layer formed on the cell to avoid the corrosive action of the liquid electrolytic bath on the sidewalls. The authors developed a new thermal-electrical model coupling ANSYS Mechanical software and Python, able to compute the transient heat balance of an AEC, including the phase change dynamic of the side ledge and thermal contact resistance. It has been found to give both accurate results and improved computational time. |
