RESISTANCE ANNEALING FURNACE TO ANNEAL AT LEAST ONE METAL OR METAL ALLOY WIRE, STRAND, STRING, WIRE ROD OR STRIP
Document Type and Number:
WIPO Patent Application WO/2017/168385
Kind Code:
A9
Abstract:
Resistance annealing furnace to anneal at least one metal or metal alloy wire, strand, string, wire rod or strip, the annealing furnace (1) having at least two electric axles (5-7) provided with respective electric contact rings (8- 10) for conveying the metal or metal alloy wire (2), strand, string, wire rod or strip, and a DC voltage generator (14), which can be supplied by an AC voltage (Uac) to generate an annealing voltage (Uann) applied between the two electric axles (5-7) so as to produce an electric current in the portion (16, 17) of the metal or metal alloy wire (2), strand, string, wire rod or strip extending between the two electric axles (5-7), which provokes an annealing due to the Joule effect. At least one of the electric contact rings (8-10) is made of a non-metal electric conductor material, for example graphite.
