A system and method for heat treating castings and removing sand cores therefrom. The castings are initially located in indexed positions with their x, y, and z coordinates known. The castings are passed through a heat treatment station typically having a series of nozzles mounted in preset positions corresponding to the known indexed positions of the castings passing through the heat treatment station. The nozzles apply fluid to the castings for heat treating the castings and degrading the sand cores for removal from the castings.
L'invention concerne un système et un procédé de traitement à chaud de pièces moulées et d'élimination de noyaux en sable de celles-ci. Les pièces moulées sont initialement placées dans des positions indexées dont les coordonnées x, y et z sont connues. Les pièces moulées sont passées dans une station de traitement à chaud comportant typiquement une série d'ajutages montée dans des positions prédéfinies correspondant aux positions indexées et connues des pièces moulées passant dans la station de traitement à chaud. Les ajutages appliquent un fluide aux pièces moulées pour traiter à chaud les pièces moulées et dégrader les noyaux en sable à extraire des pièces moulées.
