摘　　要：电解槽启动后期的工艺技术条件控制极为重要,主要目的是形成良好的炉帮,同时炉底不能形成大量结壳,以便电解槽平稳、高效生产和延长使用寿命。在实践中总结出了350 kA电解槽高温、高分子比、高电压、高电解质、低铝水平、低氧化铝浓度的"四高两低"启动后期管理工艺制度。The process technical conditions control of aluminum reduction cell in the later period of start up is very important, the purpose of this stage is to form good hearth and a few crusts formed at the bottom, so as to stable and efficient the production of aluminum reduction cell and to prolong its service life. The process management system of 350kA aluminum reduction cell in the later period of start up was summarized in practice, it called ＇Four-high and Two-low＇ including high temperature, high molecular ratio, high voltage, high electrolyte, low aluminum level, and low alumina concentration.
