Filed:
Sep 26, 1984
Appl. No.:
6/654420
Inventors:
Richard W. Peterson - New Kensington PA
Richard L. Rolf - New Kensington PA
Richard L. Rolf - New Kensington PA
Assignee:
Aluminum Company of America - Pittsburgh PA
International Classification:
C25C 300, C25C 700
US Classification:
204243R
Abstract:
In an electrolytic cell having a floor and a boundary for the floor, the cell having a short side and a long side, the improvement including greater compressibility in the boundary on the short side of the cell, as compared to the long side of the cell, in an amount effective for accommodating longitudinally directed expansion of the floor, to counteract longitudinal cracking of the floor.
