Abstract
Information on the interface condition between metal and mould is most important, since it forms the controlling resistance in the heat flow path. Generally, in the simulation of casting the interfacial heat-transfer coefficient is modelled as a function of time. This study proposes an interfacial heat-transfer model in which the heat-transfer coefficient is a function of cast surface temperature and where the prediction of gap formation is based upon the strength of the solidifying metal shell. The solidification of a thin gravity-diecast aluminium plate is simulated by the finite element method, the numerical results being compared with experimental measurements.Keywords
