ABSTRACT:
A strand annealing furnace is provided with a tube assembly to shield or protect the strand being annealed from the hot furnace atmosphere. The tube assembly includes a long, outer, oxidation-resistant pipe and a shorter, inner easily removable, insert, protecting at least the entrance end of the tube, so that any residue from drawing lubricants will deposit within the insert rather than block and/or corrode the pipe.
