引言加入铝电解槽中理想的氧化铝加料量应能在电解质中立即溶解。然而,不可避免地有一部分氧化铝会直接沉降到槽底而形成沉淀。采用自动打壳加料系统能够控制氧化铝的加料量,但是控制氧化铝沉淀则较困难。这就需要我们能够确定出溶解于电解质中的氧化铝浓度。目前尚无对运行中电解槽的氧化铝浓度进 INTRODUCTION The ideal addition of alumina to an aluminum reduction cell should dissolve immediately in the electrolyte. However, it is inevitable that part of the alumina will sink directly to the bottom of the tank to form a precipitate. The use of automatic shell opening feeding system can control the feeding amount of alumina, but it is more difficult to control the precipitation of alumina. This requires us to determine the alumina concentration dissolved in the electrolyte. There is currently no alumina concentration into the electrolyzer in operation
