摘　　要：本文通过建立包括槽内熔体在内的模型,计算分析了多种内外因素对电解质温度及炉帮形状的影响。研究发现,初晶温度降低,电解质温度也迅速降低,侧部结壳随之变薄。而降电流和强化电流,以及压极距对炉膛的影响最大,炉膛会急剧收缩或扩张。槽壳表面的散热措施,如强制风冷和散热片,对降低槽壳表面温度效果非常显著,但对调节电解质温度的作用不明显。Based on building model including melt, internal and external influence factors on the aluminum temperature and the shape of ledge are calcu-lated and analyzed. The results show that with the decrease of liquidus temperature, the bath temperature decreases drastically and the side ledge thins,while current modulation and ACD squeezing seriously influences the ledge profile, but they impact mildly on bath temperature ; external cooling measuressuch as cooling fins and forced cooling play remarkable role in reducing shell temperature, but not the same extent on bath temperature.

关 键 词：电解质温度 炉帮厚度 槽壳温度 内外影响因素
