摘　　要：预焙阳极铝电解槽的焙烧启动直接影响其槽寿命。本文首先阐述了铝液焙烧启动、焦粒焙烧启动和燃气焙烧启动三种技术的优缺点,然后结合现场生产实践,详细介绍了某铝厂240 k A预焙阳极铝电解槽燃气焙烧启动的整个过程。通过燃气焙烧启动技术的应用,达到节省启动能耗的目的。The baking and start- up directly affects the pot life of aluminum reduction pot. In this paper, the advantages and disadvantages of aluminum liquid, coke and gas baking and start - up technologies are described, then the whole gas baking and start - up process for 240kA aluminum reduction pot in a smelter is introduced combining with the production practice. Through the application of gas baking and start - up technology, the start - up energy consumption is saved.

关 键 词：预焙阳极铝电解槽 焙烧启动 槽寿命 节能
