RT Journal Article SR Electronic A1 Bredl, Jan T1 Measurement of Heat Transfer in a Sand Mould Foundry - Optimisation of Cooling Time for Cast Iron And Ductile Cast Iron Mass Castings JF Manufacturing Technology Journal YR 2025 VO 25 IS 2 SP 161 OP 169 DO 10.21062/mft.2025.024 UL https://journalmt.com/artkey/mft-202502-0009.php AB Cast iron with nodular graphite is one of the most important structural materials that exhibit really good mechanical properties already in the as-cast condition. Nowadays, cast iron with nodular graphite is used in many areas of the manufacturing industry, the most widespread being in the engineering and automotive industries. The applicability of this material for construction purposes is mainly due to its mechanical properties, which are close to those of steel, but the production cost of cast iron is lower. This experiment was aimed at optimizing the production of ductile iron castings in the casting pits so that the foundry could produce ductile iron castings in the casting pits. Therefore, the optimization of the moulding compound database material was carried out in numerical simulation and at the same time, the heat transfer measurement of the foundry sand mould was carried out.
