Abstract

In this study, the time-dependent variation of interfacial heat transfer coefficient (IHTC) for metal molds at different mold temperatures was numerically investigated and the time-dependent interfacial heat transfer mechanisms were determined. For this purpose, IHTC, temperature distribution and heat transfer of aluminum alloy A383 for metal molds were numerically investigated. The interfacial heat transfer coefficient between the mold and the cast part was calculated at a different preheating temperature (493 K, 543 K and 593 K) and the time dependent temperatures of the A383 casting alloy cast at 973 K. The calculated temperatures were used to define the impact of mold temperature on the IHTC. The average IHTC for casting temperatures of 493 K 543 K and 593 K were calculated as 16453 W/m2K, 17441 W/m2K and 18127 W/m2K, respectively. As a result, the IHTC increased with rising up mold temperature.
