Premoulded, highly densified artificial carbon articles, in particular carbon anodes for aluminium dry electrolysis (melt electrolysis) are produced in a combined process, namely by moulding the green artificial carbon articles, preheating the articles by means of heat recovered from the cooling of the finally fired artificial carbon articles, and inductive final firing in an apparatus which comprises a mixing and moulding installation (3, 4), a twin-channel tunnel oven (8) for preheating and cooling with heat recovery, an induction furnace (19) and gas treatment devices.
