The TCC technology was successfully applied to two of 160kA prebake cells in Pingguo Aluminum Company. It was shown that no tear-off of TCC was indicated after starting up of the cells. The operation of coating cells was improved to keep good shape of cell chamber, reduce the formation of sludge on the cell bottom, and gain more uniform current distribution.

The TCC was still good and in integrity after 12h of electrolysis. The TCC technology was successfully applied to two of 160kA prebake cells in Pingguo Aluminum Company. It was shown that no tear-off of TCC was indicated after starting up of the cells. The operation of coating cells was improved to keep good shape of cell chamber, reduce the formation of sludge on the cell bottom, and gain more uniform current distribution.

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。
