Abstract

A mathematical model is developed and an original technique is proposed in order to evaluate the effect of pressure on properties during the formation of crystallizing metal. It has been established that, for an efficient process of heat exchange between the casting and the mold, it is necessary to increase the wall thickness of the mold gradually from the periphery to the center. Relationships are obtained that make it possible to calculate the amount of heat that the metal exchanges with the mold at the first stage. The results have made it possible to find out that the process control should be brought into line with the rate of crystallization. In addition, the volume of metal required for the compensation for shrinkage of the crystallized metal should be pressed into the casting in the course of each fixed period of time.
