分析了金属型离心浇注Ti－15V－3Cr－3Sn－3Al（Ti－15－3）合金铸件过程中浇口杯内压力分布；推导出了离心浇注过程中产生的附加压力项ΔP的表达式以及最大转动角速度ω0max（r／min）与金属液高度H和浇口杯直径D0之间的关系。计算结果表明，离心浇注过程中，作用在铸件上的压力由静态压力和附加压力两部分组成，静态压力由金属液高度决定，而附加压力主要由金属液密度以及旋转角速度来决定。浇口杯高度和直径之间应满足一定的函数关系，其金属液高度为浅口杯高度的一半时较为理想。最大允许旋转角速度值随金属液高度和浇口杯直径的增大而减小。
The pressure distribution in the cup of centrifugal casting of Ti-15V-3Cr-3Sn-3Al (Ti-15-3) was analyzed. The expression of additional pressure term ΔP during centrifugal casting was deduced and The relationship between the maximum rotational angular velocity ω0max (r / min) and the height H of the molten metal and the diameter D0 of the sprue cup. The results show that the pressure acting on the casting during centrifugal casting consists of static pressure and additional pressure. The static pressure is determined by the height of the molten metal. The additional pressure is mainly determined by the density of the molten metal and the rotational angular velocity. Between the height and diameter of the sprue cup should meet a certain functional relationship, the height of the molten metal is as good as half the height of the shallow cup. The maximum allowable rotational angular velocity decreases with the height of the molten metal and the diameter of the sprue cup.
