摘要
提出了"五低三窄一高"新工艺技术,并开发了与新工艺技术相配套的智能多环协同优化与控制技术。应用该新技术对郑州龙祥铝业有限公司原设计容量为154kA的铝电解系列134台电解槽进行技术升级,在无需改变现有铝电解槽结构的条件下,成功地将其升级为一个高效节能型180kA级铝电解系列,为期9个月的工业应用表明,平均槽电压降低到3.83V^3.88V,阳极效应系数降低到0.02次/(槽.日),平均电流效率提升到93.5%,吨铝节电1183kWh。
A new technics represented as＂ five low - three narrow - one high＂ has been put forward in this paper, and an intelligent optimization and intelligent polycyclic cooperative control has been developed to cooperate with this new process, both of them were applied to the technology promotion of the 154kA electrolysis series with 134 ceils of Zhengzhou Longxiang Aluminium Industry Co, Ltd, and succeeded in strengthening the current to 180kA and transforming the cells to the energy -saving ones with high efficiency on, the condition that the cell structure needs no thange. The industrial application lasting 9 months shows that the specific ouqmt increases by 12.5%, average cell voltage reduces to 3.83V - 3.88V, the coefficient of anode effect falls to 0.02, average current efficiency upgrades to 93.5 %, and the energy consumption reduces by 1183 kWh/t - Al.
