ABSTRACT:
A system for heating wire during a wire drawing process which comprises one or more cylindrical silicon carbide tubes each having an aperture in the side wall thereof. A flame projecting burner is situated adjacent the aperture in the side wall of each tube for projecting a flame through the aperture onto a wire passing through the cylindrical tube. The arrangement causes the wire to be heated by direct impingement of the flame onto the wire, residual flame and hot gases redirected by the cylindrical tube longitudinally of the wire and radiant heat from the cylindrical silicon carbide tube.
