Abstract

PURPOSE:To perform non-oxidative heat treatment easily by consuming O2 by combustion of an organic material of a fixed boiling point range, coated on a metal filament or wire, by heating in a furnace of an inert gas atmosphere. CONSTITUTION:A metal filament or wire 6 is sent into the tank 3 storing an organic substance of a boiling point of 100-300 deg.C, e.g., the liquid paraffin 4, then passed through the throttle roll 5 to remove an appropriate amount of the paraffin 4 adhered to the surface of the filament or wire 6, and lastly sent into the furnace 7 where as the inert gas 9 and the metal filament or wire 6 are sent to the arrow mark 13 direction while being heated gradually, the paraffin 4 adhered to the surface is vaporized and reacted with O2 present in the inert gas 9. Thus, as they are advanced toward the exit 14 of the furnace 7, the metal filament or wire is heated in non-oxidative atmosphere while consuming O2 present in the furnace 7, cooled near the exit 14, and then wound around a winder for the heat-treated metal filament or wire 12.
