摘　　要：研究了氧化铝浓度与槽电阻、电流效率和阳极效应系数之间的关系,通过对氧化铝浓度与电流效率关系曲线和氧化铝浓度与槽电阻关系曲线的分析研究,发现低温铝电解生产工艺中当氧化铝浓度范围为1.5%～3.5%时,既可获得较高的电流效率,又可防止阳极效应的发生,为铝电解的模糊控制技术提供依据.This paper studies the relation between alumina concentration and groove resistance, current efficiency and anode effect coefficient. Through the analytic research of the relation curves between alumina concentration and electric current, alumina concentration and electric resistance, it is found that the best controllable scope of alumina concentration in the productive technology in a low temperature is between 1.5 % to 3.5 %. At the same time, it is found that it can acquire more electric current, and it can also prevent the anode effect.
