为保证高炉安全生产，保护铁口及炉缸的铁口周围部分，减轻铁口砖衬的侵蚀，探讨利用含钛炮泥维护铁口。

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。

The theoretical analysis and the experimental results consistently show that, the oxidation of Si〓N〓-bonded SiC refractory adheres to the parabolical type rule of oxidation and the oxidation in the condition of actual BF operation is passive one.

在此基础上，综合SiC砖蚀损过程研究结果，阐述了炉墙传热过程与其蚀损的相互关系，进而探讨了高炉用Si〓N〓结合的SiC砖的适宜条件，提出了控制碱蚀、减轻热震破坏以及改善高炉用SiC质砖衬的使用效果的技术方向和途径。

The expected benefits will be a reduced reblow rate, a tap to tap saving (a gain of 2 - 3 minutes per heat can be expected), as well as an increased refractory lining life and process yield.

预期的效益在于减少再吹炼的比率、节省出钢时间(预计每炉能缩短2～3 min)，同时延长耐火炉衬的寿命，提高生产产量。
