Open Access Graduate Research Paper


Besides proper design of gating and risering systems, there are several methods used to control and modify solidification behavior of cast alloys. Within these methods, the most widely used are local cooling aids employing cooling fins (thin segments attached to problematic areas of casting) or external chills (metal inserts placed into mold walls to accelerate heat withdrawing from potential hot spot). The later helps to promote directional solidification when traditional methods are not possible to use due to limitations related to the casting design. Despite relatively wide application in aluminum foundries, there are no specific recommendations on cooling aids parameters selections have been published.

The objective of the study was to compare effectiveness of different local cooling aids and to develop practical recommendations on their applications. The research has been conducted via computer modeling of solidification process, based on finite difference computation method (FDM).
