摘 要: 在4台100 kA铝电解槽上开展高润湿耐渗透TiB2/C复合阴极材料的工业试验研究。工业试验结果表明:与对比槽相比,试验槽阴阳极电流分布均匀,可有效降低和减缓钠的渗透速率,平均炉底压降降低了约40 mV,平均电流效率由92.6%提高至93.9%,吨铝节电498~657 kW·h,且TiB2/C复合阴极具有良好的耐磨性和长的使用寿命。
关 键 词: 有色金属冶金;铝电解;TiB2/C复合阴极;槽电压;电流效率

Abstract: The experimental studies for industrial application of TiB2/C composite cathode in four 100 kA aluminum electrolysis cells were developed. Industrial test results show that compared with the cells using common carbon cathodes, the test cells have uniform current distribution, and can effectively reduce the sodium permeation rate. The average bottom voltage drop of test cells decreases by about 40 mV, and the average current efficiency increases from 92.6% to 93.9%. Power energy of 498-657 kW穐/t-Al is saved, and TiB2/C composite cathode has good wear resistance and long life.
Key words: non-ferrous metallurgy; aluminum electrolysis; TiB2/C composite cathode; cell voltage; current efficiency
