ANODE YOKE, ANODE HANGER AND ANODE ASSEMBLY FOR A HALL-HÉROULT CELL

摘要

An anode yoke (1; 101) for use in an electrolytic cell for the electrolytic production of aluminium using the Hall-Heroult process, said yoke comprising: a body (2; 102) intended to be connected to said anode rod (16;1 16), and a plurality of arms (3A-3D, 4A-4D; 103A, 103B, 104A, 104B) which extends each from said body, each arm being intended to be connected to a carbon anode (11, 11'; 111), wherein each arm comprises a reduced cross section area (39, 49), said anode yoke being characterized in that said reduced cross section area comprises at least one hole (38, 38', 48; 138, 148) which leads on at least one peripheral face (34, 35, 44, 45) of said arm.
