摘要： The present invention relates to nonferrous metallurgy, in particular to the electrolytic production of aluminum, more particularly to a structure of a cathode assembly of a reduction cell for production of aluminum. A lining of a cathode assembly of an aluminum reduction cell is provided which comprises a thermal insulation layer and a fire-resistant layer consisting of no less than two sub-layers, wherein the porosity of the thermal insulation layer and the fire-resistant layer increases from an upper sub-layer to a bottom sub-layer and the thickness ratio of the fire-resistant layer and the thermal insulation layer is no less than 1/3. Also, the present invention provides a method for lining a cathode assembly of a reduction cell and a reduction cell having the claimed cathode assembly lining. The invention is aimed at the reduction of the cyanide content in upper thermal insulation layers and to provision of conditions for material reuse in the thermal insulation layer, waste reduction and improvement of the environmental situation on aluminum production facilities.

摘要： The cathode collector bar end portion extending through a window in a sidewall of an electrolytic cell for refining aluminum is snugly received in a central opening of a seal assembly. Such seal assembly maintains a hermetic seal preventing ingress of air through the sidewall window while permitting longitudinal (horizontal) movement of the collector bar and also movement in a vertical plane (side to side, or up and down, or diagonally) which can be caused by changing heat conditions inside the cell.

摘要： A drained cathode cell for the electrowinning of aluminium comprises a cell bottom (20) arranged to collect product aluminium and thermic insulating sidewalls (55,55null) lined with a molten electrolyte resistant sidewall lining (50) which is made of material liable to react with molten aluminium, in particular containing silicon carbide, silicon nitride or boron nitride. The thermic insulating sidewalls (55,55null) inhibit formation of an electrolyte crust on the lining (50), whereby the lining (50) is exposed to molten electrolyte. The cell bottom (20) has a peripheral surface from which the insulating sidewalls (55,55null) extend generally vertically to form, with the cell bottom, a trough for containing molten electrolyte and aluminium produced on at least one drained cathode (32). The peripheral surface of the cell bottom (20) is arranged to keep the product aluminium from contacting and reacting with the molten electrolyte resistant sidewall lining (50) above and around the entire peripheral surface.
