Abstract: Part of an atmosphere gas in a heating zone and/or a soaking zone is sucked out and is cooled through a high-temperature gas passage of a heat exchanger by heat exchange with a gas in a low-temperature gas passage, then cooled through a gas cooler, then dehumidified to a dew point of −45° C. or less in a dryer, then heated through the low-temperature gas passage of the heat exchanger by heat exchange with a gas in the high-temperature gas passage, and returned to the heating zone and/or the soaking zone. Part of gas flowing from the dryer toward the low-temperature gas passage of the heat exchanger is returned to a cooling zone. These can achieve a low dew point of −45° C. or less with high energy efficiency.

Abstract: An electric wire comprises a non-oxidized conductor of copper alloy having no outer coating and in direct contact with a PTFE-based sheath. It is fabricated as follows: providing a copper alloy conductor without an outer coating; forming a sheath of a PTFE-based material around the conductor; and heating the wire in order to evaporate the lubricant and sinter the sheath. In order to avoid oxidizing the copper during the heating step, the wire is heated mainly in an atmosphere having a low oxygen content. The lubricant evaporation and/or sintering line for stabilizing the sheath of the electric wire comprises one or more ovens, each having an enclosure in which an atmosphere having a low oxygen content is maintained.
