ABSTRACT:Aluminum cell is the main equipment in the aluminum production. The structure of aluminum electrolytic cell was calculated and designed on the basis of a lot of literatures. The main contents of the design include: the energy balance calculation, the voltage balance calculation, the material balance calculation to get familiar with the aluminum electrolysis process. On the basis of the metallurgical calculation the main equipments and electrolysis plant were designed. The mature basic process parameters was chosen in current aluminum electrolysis production technology of the current intensity= 250kA and the current efficiency = 94%. At last, the main equipment drawing, the equipment connection drawing of the alumina plant-wide and the plane and elevation of the alumina electrolysis plant are drawn up.
Keywords: aluminum electrolysis; technological process; metallurgical balance calculation; Na3AlF6 -Al2O3 molten salts electrolysis
