摘要: 通过解球坐标系下的一维热传导方程,给出了球形金属液滴在冷却凝固过程中固相温度分布、界面位置及冷却时间的函数关系,并由此推导出了纯液相冷却过程中的温度分布与时间的关系及等温凝固时间与球直径的关系。

Abstract: The differental equation for the relationship of temperature distribution in solid, interface distance and time during cooling and solidificatian Processing of metal drop has been solved in one dimensional equation of heat conduction in spheriodal coordinate, and the relationships of tempertuer distribution in liquid and time during liquid cooling, and of solidification time at invariant temperature and spherical diameter are inferenced from the solution.
