ELECTROLYTIC REDUCTION CELL

摘要

Electrolytic reduction cell for prodn. of molten metal by electrolysis of a molten electrolyte includes a linear baffle member extending transversely of the cell and extending upwardly from the cell floor to a posn. close to the level of molten metal in the cell. The baffle is formed with energy-absorbing restricted flow channels. Used e.g. in the prodn. of Al by electrolysis of alumina in a fused chloride electrolyte. The baffle members exert a damping effect on the flowng molten metal and reduce the amplitude of its wave motion so that the modes can be maintained at a smaller spacing from the metal/electrolyte interface.
