The main source of damage are the micro- and macro-thermal stresses appearing in each cycle. As the cost of furnace instrumentation forms a significant part of the total furnace cost, in designing this type of tooling it is important to develop solutions that delay the damage formation process and thus extend the casting operation time. In this article, two structural modifications introduced to pallets castings to reduce thermal stresses arising at various stages of the cooling process are proposed. The essence of the first modification consists in making technological recesses in the wall connections, while the aim of the second one is to reduce the stiffness of the pallet by placing expanders in the external walls. Using the results of simulation analyses carried out by the finite element method, the impact of both proposed solutions on the level of thermal stresses was evaluated.}, type={Artykuły / Articles}, title={Design Options to Decrease the Thermal Stresses in Cast Accessories for Heat and Chemical Treatment Furnaces}, URL={http://czasopisma.pan.pl/Content/109221/PDF/AFE%204_2018_24.pdf}, doi={10.24425/afe.2018.125181}, keywords={Application of information technology to the foundry industry, thermal stresses, Cast grates, Heat treatment equipment}, }
