A system and method for heat treating castings (13, 53) and removal cores (54) therefrom. The castings (13, 53) are initially located in indexed positions with their x, y, and z coordinates known. The castings (13, 53) are passed through a series of nozzle stations (41, 63) each having a series of nozzles (42, 64, 64') mounted in present positions corresponding to the known indexed positions of the castings passing through the nozzle stations (41, 63). The nozzle (42, 64, 64') apply heated fluids to the castings (13, 53) for heat treating the castings (13, 53) and dislodging the sand cores (54) for removal from the castings (13, 53).
L'invention concerne un système et un procédé pour assurer le traitement thermique des pièces coulées (13, 53) et le retrait des noyaux (54). Les pièces coulées (13, 53) sont initialement placées dans des positions indexées avec leurs coordonnées x, y et z connues. Ces pièces coulées (13, 53) passent dans une série de postes (41, 63) comportant plusieurs buses (42, 64, 64') fixées dans des positions correspondantes aux positions indexées connues desdites pièces coulées passant dans les postes susmentionnés (41, 63). La buse (42, 64, 64') applique des fluides chauffés aux pièces coulées (13, 53) pour assurer leur traitement thermique et en extraire les noyaux de sable (54) .
