REDUCED VOLTAGE DROP ANODE ASSEMBLY FOR ALUMINIUM ELECTROLYSIS CELL
摘要
<p>Anode assembly 1 for aluminium electrolysis cells comprising carbon anodes 2 with stubholes 5 and an anode hanger 3 having stubs 4, whereas the anodes 2 are fixed to the anode hanger 3 by cast iron 6, characterized in that the stubholes 5 are fully or 5 partially lined with an expanded graphite lining 7. Such anode assemblies provide reduced voltage drop across the interface between the cast iron 6 and the carbon anode 7 and thus increase cell productivity significantly. Further, mechanical stresses in the stubhole 5 area are reduced. By further forming a collar 8 from the lining 7, th spilling of cast iron over the anode 2 surface is prevented and optionally a protective shot plug or a protective collar prevent direct contact of the hot electrolytebath with the stub 4 and the cast iron 6.</p>
