85kA预焙槽电解温度分子比控制模式的应用研究

Application study on controlling mode for electrolytic temperature and cryo lite mole ratio in85kA prebaked cells

本文阐述了85kA预焙槽实际生产中电解温度及分子比之间的高度相关性关系,并根据这种相关性建立了稳定的氟化铝添加控制模式,利用我公司铝电解自动控制系统中的相关模型实现铝电解温度及分子比的有效控制,取得了良好的技术经济指标。

Based o n actual production using85kA prebaked cells,the high correlativity between the electrolytic temperature and cryolite mole ratio is expounded.Moreover,based on such a correlativity,the controlling mode for stable addition of aluminium f luoride is estab-lished,and then taking advantage of the correlative model of the automatic control system for electrolytic aluminium production in our corpo ration,an effective control of electrolytic temper-ature and the mole ratio is accomplished in success with the result of better techno-economi-cal performa nces.
