The paper discusses the impact of the geometry of foundry pallet components on the value of temperature gradient on the wall crosssection
during heat treatment. The gradient is one of the most important factors determining the distribution of thermal stresses in these
items. Analysis of quantitative simulation was carried out to detect possible effect of the type of connection between pallet walls and
thickness of these walls (ribs) on the interior temperature distribution during rapid cooling. The analysis was performed for five basic
designs of wall connections used in pallets. Basing on the results obtained, the conclusions were drawn on the best connection between the
ribs in foundry pallets.
