摘　　要：磁场是电解槽磁流体稳定性的决定性因素,本文对铝电解槽的磁流体稳定性进行研究,通过采用自均衡网络化母线技术降低电解槽垂直磁场,改造后的垂直磁场平均降低47.5%,且四个象限磁场强度分布均匀。通过瞬态磁流体模型及流动场稳定性分析验证,500s左右后电解槽可自行恢复稳定状态,界面变形减小1.2cm,证明采用自均衡网络化母线技术后的电解槽自平衡能力及抗波动能力均得到增强,从而节省直流电耗150kWh/t-Al。Magnetic field is a decisive factor for the magnetic fluid stability of electrolytic cells.In this paper,the magnetic fluid stability of aluminum electrolytic cells is studied.The vertical magnetic field of electrolytic cells is reduced by using self-balancing network busbar technology,which is cut down by 47.5%on average after transformation,and the magnetic field intensity distribution in four quadrants is uniform.The transient magnetic fluid model and the stability analysis of the flow field show that the electrolytic cell can be restored to a stable state after about 500 s,and the interface deformation is reduced by 1.2 cm,which proves that the self-balancing ability and anti-fluctuation ability of the electrolytic cell are enhanced after the self-balancing network busbar technology is adopted,thus saving 150 kWh/t-Al of DC power consumption.
