title = "Thermal Boundary Conditions For Computer Simulation Of Grey Cast Iron Solidification In Sand Moulds",
abstract = "By exploiting the results of solidification modelling foundries can enhance the quality and reduce the cost of their casting processes. However not enough information exists on the thermal boundary conditions, which control the transfer of thermal energy stored in liquid metal to the mould via the metal/mould interface during solidification. This is quantified by the heat transfer coefficient (h.t.c.). An experimental and numerical study was carried out to find the magnitude and variation of the h.t.c. in cylindrical castings during the solidification of grey cast iron in green sand moulds. The h.t.c. values were calculated using a time marching solution to the inverse heat conduction problem. The variation of h.t.c. with metallostatic head was analysed. There is a wide scatter in green sand thermal properties due to the large number of variables involved in mould manufacture including green sand compaction and water content. The sensitivity of the calculation to uncertainties in the thermophysical properties of the green sand was evaluated.",
