Abstract

See full text

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 ⅓. 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.
