Abstract

PURPOSE: To reduce the gradiant of a vertical magnetic field in molten Al by a method wherein a cathode current collecting rod is divided into two groups comprising equal numbers respectively and, in an upstream side, current is collected to both end positions of each side part cathode matrix wire and, in a downstream side, to a central position thereof.
CONSTITUTION: An electrolytic tank 1 has 16 cathode current collecting rods 2-1W2-16 provided to a tank bottom part thereof and divided into two groups 2-1 W2-8 and 2-9W2-16. In an upstream side, the first group is connected to a side part cathode matrix wire 3-1 and, in a downstream side, to a side part cathode matrix wire 3-3 and, in an upstream side, the second group is connected to a side part cathode matrix wire 3-2 and, in a downstream side, to a side part cathode matrix wire 3-4. To those side part cathode matrix wires, current is collected and, by each connecting matrix wires 4-1W4-4, power is supplied to an anode matrix wire 5 of the next electrolytic tank. Thereby, current collected to the side part cathode matrix wires is sent in a divided condition and concentration of current is not generated.
