当电解槽槽型,阳极电流密度,槽内衬保温结构和母线配置等设计参数确定之后,就有一个选择最佳铝液高度使电解槽电能效率最高,即电耗率最低的课题。试验说明,在使用国产中间状氧化铝的条件下,135千安边部加工预焙阳极电解槽的铝液高度为28厘米时,电耗率最低;而135千安中间下料预焙阳极电解槽铝液高度为23～24厘米时,则电耗率最低。降低铝液高度可以减少格体散热损失,减少槽底沉淀,降低槽底电压降,防止阳极氧化,降低阳极碳耗等,对降低铝电解生产的电耗率十分有利。但,当
After the design parameters such as cell type, anode current density, slot liner insulation structure and busbar configuration were determined, there was a subject that selected the best aluminum liquid height to make the cell have the highest energy efficiency, ie, the lowest power consumption rate. The experiment shows that the power consumption rate is the lowest when the height of molten aluminum of 135 kanneal prebaked anolyte cell is 28 cm with the use of domestic intermediate alumina, while the 135 kan intermediate prebaked anodic electrolysis Trough aluminum liquid height of 23 to 24 cm, then the lowest power consumption rate. Reducing the height of liquid aluminum can reduce the lattice heat loss, reduce the sediment bottom, reduce the voltage drop at the bottom of the tank, prevent anodic oxidation and reduce the anode carbon consumption, which is very beneficial to reduce the electricity consumption rate of aluminum electrolysis. But, when
