Abstract
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.
