铝电解生产中影响阴极炭块使用寿命的因素分析

ANALYSIS ON THE FACTORS INFLUENCING THE SERVICE LIFE OF CARBON CATHODES IN THE ELECTROLYSIS PROCESS

介绍了在铝电解生产中 ,影响阴极炭块寿命的 3个主要因素 ,即金属钠的渗透、电解液和铝液的侵蚀。

The three major factors influencing the service life of carbon cathode in the electrolysis process—the penetration of metal Sodium, the corrosion by bath and liquid aluminum, are discussed in detail. Several methods about increasing the service life of carbon cathode are introduced.
