CATHODIC CELL CASING FOR ALUMINIUM PROCESSING Russian patent published in 2008 - IPC C25C3/08 

FIELD: metallurgy.

SUBSTANCE: cathodic casing of aluminium cell includes fettled inside the metallic bath with longitudinal walls and with windows for blooms, butt walls, bottom and flange, installed inside of rigid frame, generated with longitudinal all-welded ribs. On the longitudinal walls of the metallic bath of cathodic casing between the ribs it is installed 1 to 10 vertical steel cooling flippers. The length of the vertical flippers is 0.2-1.0, and breadth 0.05-0.4 of distance from the upper part of the window bloom till the flange. The vertical cooling flippers are installed on the longitudinal walls of the metallic bath the way, that the lower par of the flipper is situated from the upper part of window blooms at the distance not exceeding 0.6 distance from upper part of the window for bloom till the lower part of the flange, and the upper part of the flipper is situated from the lower part of the flange at the distance not exceeding 0.8, of distance from the upper part of the window bloom till the flange.

EFFECT: it is provided the exceeding of the cell life time.
