[origin: WO2008073031A1] A method for the heating of anode blocks, which anode blocks (2) are used during the production of aluminium and comprise contact holes (3) into which it is arranged that electrical contacts are to be attached. The invention is characterised in that the holes (3) are caused to be heated by means of radiative heat from electri- cal resistive elements (4, 5, 6) arranged to be used at high temperatures, in that the wire of the elements (4, 5, 6) is in the form of shanks with two or more legs, in that each one of the elements (4, 5, 6) is caused to be arranged in a cup (7, 8, 9) with an open end surface, in that one cup (7, 8, 9) for each hole (3) in the anode block (2) is caused to lie in front of the hole(3) in question. The invention relates also to an arrangement.
