Summary:In recent years, numerical simulations have been playing an increasingly important role in the process of casting optimization. The reliability and validity of numerical simulation results are significantly determined by the accuracy setting of the interfacial heat transfer coefficient (IHTC). In this paper, the change law of IHTC between ring type castings and cores under different conditions is systematically investigated by using the Beck inverse algorithm, numerical simulation method and temperature field measurement data with AISI1045 steel as casting material and no-bake furan resin bonded sand as core material. The results show that the change of IHTC with time is in the form of “bimodal” after the cavity is poured, and the value increases rapidly to the maximum after pouring, and then decreases gradually to the minimum, followed by a slow increase and slow decrease process. The accuracy of the calculated IHTC was verified by using Procast software.
