Straightening and machining of the lugs of cast anodes used in electrolytic refining prior to immersion in the electrolytic cell

摘要

Anode lug 2 of cast anode 1 used in electrolyte refining of metals is straightened by horizontal compression and bent by vertical compression so that the tip 3 of the lug is slightly lower than the foot 4 of the lug, and a piece 7 is removed from the bottom surface of the lug by cutting eg. by sawing to obtain a smooth surface for ensuring a good contact with a busbar 5 supplying current to the anode when the anode is immersed in the electrolytic cell suspended by the lug 2.
