ABSTRACT:
In order to effectively heat treat and decore a metal casting, and thereafter fully reclaim the core sand for reuse, a two-stage system processes metal castings and core sand formed of sand and binder. The two-stage system includes a first stage for removing the core sand from the metal casting while at the same time heat treating the metal casting, and it also includes a separate, second stage for reclaiming the core sand. For this purpose, fluidized and heated sand is utilized as the castings and sand are conveyed together in the first stage and the sand alone is conveyed in the second stage for recirculation of at least a portion of the sand to the first stage.
