Abstract: The relation of parameters concerning the continuous unidirectional solidification process was established by the theoretical analysis of the heat transfer. Based on the relation, the ways of stabilizing the continuous unidirectional solidification process were discussed. For pure aluminium and an Al-1%Cu alloy, when the distance from the spraying position to the solid-liquid interface is smaller than 10mm, the calculated results determined by the above relation agree with the experimental data on the whole. Therefore the parameters in these cases can match well mutually, consequently the continuous unidirectional solidification process will progress steadily.
