摘　　要：阐述了电解质过热度在铝电解生产中的重要作用,分析了电解质过热度与电解槽物理场、电解生产中的电流效率以及与电解槽寿命的关系,结果表明,电解质过热度对阴阳极电流分布的影响不大,但其直接影响电流效率和电解槽寿命。提出了低过热度管理铝电解槽的技术思路。The important role of bath superheat degree in the aluminum electrolysis production is formulated and the relations of bath superheat degree to physics field, current efficiency and pot life are analyzed. The results indicate that bath superheat degree has a little effect to the cathode and anode current distribution but affects the current efficiency and pot life directly. Some technical ideals to manage the aluminum reduction cell with low superheat degree are put forward.
