ABSTRACT:
A process and apparatus for automating the hot-air baking of sand molds before casting a sample in the mold using low pressure casting techniques. The process includes dividing the cycle into characteristic phases associated with particular baking parameters, determining and recording the optimal baking parameters associated with each phase and regulating the hot air blown on the mold so as to assure correspondence between the optimal parameters and those actually obtained during an actual baking cycle. The apparatus includes an analysis electrode for measuring the concentration of volatile organic materials evaporating from the mold, a valve for controlling a hot air inlet to the mold, and a pilot apparatus for comparing the theoretical volatile organic material concentration above the mold with the volatile organic material concentration measured by the analysis electrode and for opening and closing the valve, so as to assure correspondence between the actual and the theoretical concentration of volatile organic materials evaporating from the mold. The invention can be used for the baking of foundry molds, and particularly, foundry molds for aeronautical parts.
