ABSTRACT:
Metal scrap cuttings are prepared for use in making sintered pieces. The cuttings are physically and chemically cleaned, ground in an inert atmosphere, heat treated in a reducing atmosphere, and sorted according to particle size in an inert atmosphere. Movement of the cuttings into the various treatments is performed by vibratory conveyors located in enclosures sealed from the atmosphere.
