A process for removing layers of paint or other non-metallic coatings from a coated metal hanger or the like comprising the steps of freezing the coating to embrittle it and shrink it toward the metal hanger, heating the metal hanger without heating the coating to expand the metal toward the coating, and stressing the coating by said expanding and shrinking to break and fragment the coating and cause it to fall off the metal hanger.

Debonding process for removing non-metallic coatings from metal hangers

A method and apparatus for the induction heating of a metallic material comprising the steps of forming the material into a desired shape, passing the formed material in heat exchange relationship with an induction heating means, passing the heated material directly from the induction heating means into the reaction chamber of a cooling shroud at a temperature above its lowest reaction temperature, delivering hydrogen gas and an inert gas into the reaction chamber of the cooling shroud to expose the material entering the reaction chamber to this gas mixture so as to reduce the surface oxidation on the material, cooling the material in the reaction chamber while exposing the surface thereof to the inert gas, and passing the material from the cooling shroud at a reduced temperature which is less than the reaction temperature of the material whereby the formation of heavy surface oxides is eliminated and the material has a workable hardness.

Apparatus for improving oxygen burner performance in a glass furnace having a chamber with a bottom wall connected to a roof wall by side walls, said walls having refractory surfaces, and an opening in the roof wall, comprises a burner for injecting a flame downwardly into the chamber through the roof opening with the flame being adapted to impinge against a bath of molten glass on the bottom wall of the chamber, a hopper for inserting a shower of cullet into the chamber through the roof opening, and a burner spout having a flared end for forming the shower of cullet into a shroud around the flame and for heating the shower of cullet and for forming the cullet into an annular ridge of unmelted cullet on the top surface of the molten glass bath, whereby said ridge deflects the flame upwardly when the flame bounces from the bath of molten glass so that the flame does not bounce horizontally and impinge against the near surface of the side walls, and the shower of cullet shrouds the flame and protects the furnace walls from the radiant energy of the flame and from impingement by the flame, and the cullet picks up heat from the flame before falling onto the bath of molten glass.
