摘要
Resistance annealing furnace to anneal at least one metal or metal alloy wire, strand, string, wire rod or strip, the annealing furnace having at least two electric axles provided with respective electric contact rings for conveying the metal or metal alloy wire, strand, string, wire rod or strip, and a DC voltage generator, which can be supplied by an AC voltage (Uac) to generate an annealing voltage (Uann) applied between the two electric axles so as to produce an electric current in the portion of the metal or metal alloy wire, strand, string, wire rod or strip extending between the two electric axles, which provokes an annealing due to the Joule effect. At least one of the electric contact rings is made of a non-metal electric conductor material, for example graphite.
