ABSTRACT
The presented article explores the impact that the formation of shrinkage cavities has on the heat transfer conditions in a mould. The conditions of heat dissipation have a significant impact on the rate of cooling of different parts of a casting, which in turn affects the microstructure formed in the casting. The results presented in this article allow the reader to observe changes in the solidification time and cooling curves in different parts of the casting. The formation of cavities has a different impact in different areas of the casting, and even in distant areas their impact is noticeable. The results were obtained for an example casting with a relatively simple shape, but featuring wide and narrow sections as well as faces that do not intersect perpendicularly.
