PT Journal AU Bredl, J TI Measurement of Heat Transfer in a Sand Mould Foundry - Optimisation of Cooling Time for Cast Iron And Ductile Cast Iron Mass Castings SO Manufacturing Technology Journal PY 2025 BP 161 EP 169 VL 25 IS 2 DI 10.21062/mft.2025.024 DE Ductile iron; Heat transfer; Measurement 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.
