Impact of cathode slot on current distribution in cathode carbon of an aluminum electrolyticl cell

The current distribution in a fresh aluminum electrolytic cell with slotted carbons is investigated by the Finite Element Method (FEM). The effects of the length of slots, la and lc on current distribution were also determined. The maximum local current density and its position do not change with an...
