研究了利用低熔点氟氯化物体系作电解质的低温Al2O3悬浮电解制铝新工艺,从20～80A电解槽上进行的电解结果，推导了电流效率的计算表达式．结果表明，影响电流效率的主要因素是槽电流和产物铝的表面积，增大槽电流和减小产物铝的表面积都能使电流效率增大．在100A电解槽上实验，当电解温度为750℃，γ-Al2O3平均粒度为1.22μm，电解质中F-和Cl-的摩尔比为1时，电流效率达到86．3％，制取1kgAl的电耗为11．73kW·h．
The new process of aluminum production by low temperature Al2O3 suspension electrolysis using low melting point chlorofluorocarbon system as electrolyte was studied. The calculation of current efficiency was deduced from the electrolysis results of 20-80A electrolyzer. The results show that the main factors affecting the current efficiency are the surface current of the slot current and the product aluminum, and the current efficiency can be increased by increasing the cell current and decreasing the surface area of the product aluminum. When the electrolysis temperature is 750 ℃, the average particle size of γ-Al2O3 is 1.22μm and the molar ratio of F- and Cl- in the electrolyte is 1, the current efficiency reaches 86.3% Consumption of 11.73kW · h.
