摘要： A water spray quench process and apparatus for the hardening of steel agricultural discs and like articles with minimum warpage and maximum exposure to the quenching water. A steel article heated in a furnace to a temperature above its austenitizing temperature is moved horizontally into a quenching station, supported on several support pins below the article with a positioning member above the article, and sprayed with water from a series of nozzles both above and below the article to rapidly and effectively quench the article to a minimum temperature. Once the article has been cooled by the quenching water, it is expelled from the quench station.
