摘　　要：分析了铝电解槽内衬热应力和钠膨胀应力的特点及对大型铝电解槽寿命的影响,为了减少应力对电解槽阴极内衬的不良作用,在其应力集中的侧下部设计了可压缩结构,使集中的应力在此得以有效释放。通过在两台320kA电解槽上的试验,与对比槽相比,减缓了阴极隆起的速度,减小了隆起量,可在一定程度上提高电解槽寿命。This paper analysises the characteristics of thermal stress and sodium expansion stress of aluminium reduction cell lining and the influence to the life of large-scale aluminium reduction cell caused by these stresses, in order to reduce the adverse effect by the tress on the cathode lining of aluminium reduction cell, designed compressible structure in its side lower part where the stress concentrated, so that the concentrated stress can be released availably. Experiment on two 320kA aluminium reduction ce...
