Abstract: | Heat flow from casting to mould was analysed to determine the effect of rectangular corners on the total heat absorption by the mould. It was found that mould heat absorption can be calculated by the rule of summation of plane and corner contributions. The rule, however, cannot readily be used for predicting the solidification time of a casting as a whole unless a satisfactory estimate of the heat to be removed from the casting before solidification is possible. Nevertheless, the knowledge will find use in improving the present method of numerical simulation of solidification. |
