| 摘 要： | 从减小槽内水平电流和垂直磁感应强度进而改善磁流体稳定性的角度出发,提出一种底部出电型结构铝电解槽,该种电解槽采用阴极垂直出电方式代替传统水平出电方式.在ANSYS软件平台上,建立400 kA级该槽型的电磁场模型并进行求解,根据计算结果对母线配置进行优化,得到一种可使磁场分布最优的母线结构,在该母线配置下,垂直磁感应强度最大值为1.658 mT,平均值为0.401 mT,远低于同规格普通电解槽,磁流体稳定性计算结果进一步表明该槽能在低极距下稳定运行,具有较大的节能潜力.

| Abstract: | Based on the target of reducing the horizontal current and vertical magnetic field strength,thereby improving the magnetohydrodynamic stability,a kind of aluminium reduction cell with vertical bottom was improved,in which the current flowed out of cathode vertically instead of horizontally.An electromagnetic simulated model of a 400 kA cell with this structure was developed by ANSYS software,and a bus bar scheme that can make the best electromagnetic field distribution was obtained after being optimized acc... |
