摘要

分析了金属型离心浇注Ｔｉ－１５Ｖ－３Ｃｒ－３Ｓｎ－３Ａｌ（Ｔｉ－１５－３）合金铸件过程中型腔内的流速分布，得出了离心浇注过程中充型速度Ｖ和时间ｔ与充型长度ｘ，以及转台的最大转动角速度ω０ｍａｘ与型腔直径Ｄ和长度Ｌ之间的关系。计算结果表明，离心浇注过程中，合金液的充型速度和时间是充型长度的函数，均随充型长度的增大而增大。转台的最大允许旋转角速度随型腔长度和直径的增大而减小。实验结果表明，当转台转速ω０为２８０ｒ／ｍｉｎ时，铸件内出现了气孔，从而验证了理论计算结果。

Abstract

The flow speed distribution of Ti15V3Cr3Sn3Al （Ti153） alloy melt poured in permanent mould druing centrifugal casting process has been analyzed. The relation between the filling speed

time and the filling length

as well as the maximum critical angular velocity 0max and the mould diameter D

the length L are concluded. Calculation results show that the filling speed and the filling time are the function of the filling length during centrifugal casting process

and increase with the increase of the filling length. The maximum critical angular velocity decrease with the increase of the cavity length and diameter. Experimental results show that gas holes have been formed when angular velocity is equal to 280 r/min. Furthermore

calculation results are verified.
