The initial mould temperature has b

The initial mould temperature has been fixed at 1100ºC and the pouring temperature at 1520ºC. The pouringstarts at time 160 seconds and corresponds to a flow rate equal to 10.5 kg/s.Results obtained in this first approximation are shown in Fig. 3. As can be observed, the simulation resultsbefore pouring, match quite well with experimental values. After pouring, temperatures predicted by the simulationfor ceramic shell mould are not very far from the expected, but their values are higher than the average observedexperimentally. The main difference with experimental values is found on the alloy curve, where the simulationnot only gives a slower cooling but also predicts higher solidification temperatures.
