In this paper,utilizing the technology of computer simulation,the change of aluminium electolysing cell incrustation was computed and studied under the condition of different aluminium liquid height ,and the optimal aluminium liquid height was determined.

本文利用计算机仿真技术，对我国某铝厂160kA 大型预焙阳极电解槽在不同铝液水平时槽帮结壳的变化进行了计算研究，并确定了铝电解槽正常生产时最佳的铝液高度。

The direct result of interaction of liquid and reservoir rock is the precipitation of calcite and dolomite, which will occupy some pore space of the source rocks and create cements, then the calcareous incrustation will be formed.

流体与储集岩作用的直接结果是方解石和白云石沉淀到储集岩中，它们将占有原岩的部分孔隙空间，形成胶结物，进而形成钙质结壳。

The conclusion is that volcanic rock, phosphorite, etc. contribute to the formation of the crust.

分析结果表明，调查区内的火山岩及磷块岩对结壳形成的贡献大。

Which is also lower than that of seamount crusts.

也低于海山结壳Mn/Fe的平均值。

It may be one of the reasons that there are various types of crust on individual seamount slope phase.

海山坡度与资源量分形呈三段式，引起海山坡度与资源量分段分形的原因是不同类型结壳分布叠加的结果。

The properties of TCC with ATS were as good as the TCC with HTS, better that the requirement of standard GB8744-88 for semi-graphitic carbon block. As good as TCC with HTS in industrial cells, the TCC with ATS also reduces the sodium penetration to cathodic lining, no tear-off of the coating was found after starting up of the cells. As compared with reference cells, the operation of coating cells with ATS was also improved to keep good shape of cell chamber, reduce the formation of sludge on the cell bottom, and gain more uniform current distribution. The ohmic drop of TCC cell bottom was lessened by 11. 5mV. The current efficiency was increased by about 1. 48% in average. It was estimated that the TCC life could be 44 months. Obviously, the TCC with ATS could also improve the performance of industrial cells, save energy, and increase the cell life.

对常温固化涂层槽的考核表明，与高温固化涂层槽一样，阴极内衬对钠的吸收减少，钠渗透速度减缓，从而减小钠膨胀危害，减少了铝电解槽早期破损的几率；启动后，常温固化涂层不脱落，同样具有良好的粘接性能；与对比槽相比较，常温固化涂层槽正常生产后，阴极表面干净、光洁，无沉淀或结壳，炉膛规整，阴极、阳极电流分布均匀，炉底压降降低（平均降低11.5mV），电流效率提高（平均提高1.48％）；涂层在电解槽内存在的时间可达到44个月以上；常温固化涂层同样可以起到改善电解槽工作状态、节能降耗、延长槽寿命的作用。
