METHODS AND APPARATUS FOR HEAT TREATMENT AND SAND REMOVAL FOR CASTINGS

摘要

A system and method for heat treating castings and removing sand cores therefrom. The castings are initially located in indexed positions with thei r 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 passi ng 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.
