摘要：The wire (1), prior to this treatment, has been held at a temperature greaterthen the transformation temperature AC3. The wire (1) is cooled and then thepearlitization treatment is carried out, this cooling and pearlitization treatment beingcarried out by causing the wire (1) to pass into at least one tube (3) containing a gas (12)virtually free of forced ventilation, the tube (3) being surrounded by a heat transfer fluid(9). …Device (100) permitting the implementation of this method. …Methods and
complete installations for thermal treatment of carbon steel wires (1) using this methodor this device. Steel wires (1) obtained according to these methods and/or with thesedevices and these installations. ……
