Soderberg's cell there is the problem of overheating of the anode paste and increasing mass of the bakedome in the center of the anode and low temperatures (down to freezing in winter) in the periphery. Increasing the height of the bakedome in the central part affects the formation of the anode and consequently on the physical and mechanical properties of the anode, increasing the porosity, electrical resistance and reducing mechanical strength [1]. This paper presents the simulation results of cell's temperature fields (S8-BM) with anode's cooling fins.
