Definitions

  • a pre-baked carbon anode is normally worn out after approx. 30 days in the cell due to the consumption of the carbon material it consists of. It then must be replaced.
  • the worn out anode (butts) is transported to a facility where the studs of the anode hanger is cleaned by removing rest material of the anode together with cast iron residues. Commonly, this is performed by the use of mechanical frapping tools.
  • the use of the present cast material may facilitate the re-use of the material, as the high value Cu part is located at the exterior of the steel part.
