    摘要： The present invention concerns a method and means for application of anode covering material (ACM) in an electrolysis cell for aluminium production where the cell being of Hall-Heroult type with prebaked anodes. The cell comprises a cathode pot with a rectangular footprint and a superstructure with a gas collecting hood that lays onto the top of the cathode pot. A floor construction (29) at least substantially surrounds the cell at a level below the top of the cathode pot and ventilation openings (28) provided with grates are arranged in the floor in the close vicinity to the cell. The superstructure's hood is provided with removable lids (20) that are removed for giving acess to the cell's anodes (21) through openings. ACM is applied via a feed tube (1, 1') to cover the anodes (21) and the deposit of ACM is supported by a shuttering (40). The shuttering (40) comprises a portion that rest onto the top of the cathode pot in the bottom sector of the opening, and further having a shuttering plate (41) that is tilted towards the anode(s) (21) at an angle (a), thus restricing ACM from flowing out of said opening during application of it. The shuttering plate can have a flap shuttering plate (46) attached to its upper portion. The invention also comprises a movable applicator plate (3) arranged to the ACM feed tube (1') and a horizontal plate (50) that covers the ventilation openings (28).

    摘要： An anode for use in an electrolysis process for production of aluminium in cells of Hail-Héroult type, the anode comprises a body or block (120; 20) of calcinated carbonaceous material connected with an electrical current lead, where said current lead being connected with an anode rod (103; 3) and further being part of an anode hanger (101; 1). The current lead comprises at least one metallic suspension plate(s) (104; 4. 4′) with vertically oriented redding plates (105 105′″,5, 5′) at least partly embedded by their lower partly in corresponding recesses (113, 113″″, 13. 13′; 100, 100′) in the top of the carbonaceous block (120; 20} and further connected by mechanical fixation means (108; 8; 14, 16). Said recesses are wider than the rodding plates and being filled with an electric conductive particulate material only. It Is also described a method for processing an undercut recess (10) in the an ode top for mechanically fixing the anode block (20) to a protrusion (8) on the current lead.

    摘要： An electrode for production of aluminium metal by electrolysis of an aluminium containing compound dissolved in a molten electrolyte, where the electrowinning process is performed in smelting cells of conventional Hall-Hèroult design. The electrode comprises a calcinated carbon containing body being integrated with at least one composite metallic conductor comprising conducting elements of a Fe containing material and conducting elements of a Cu containing material. The composite conductor comprises a barrier layer material at the interface between the two conducting materials. Barrier materials of ceramic, Refractory Hard Materials (RHM), and of metallic types are proposed as well as methods for their application.
