摘要

阀体零件在铸造过程中极易产生缩松、缩孔等缺陷。基于ProCAST软件对阀体零件铸造的充型和凝固过程进行了模拟

预测铸造过程中阀体可能产生的缩松、缩孔等缺陷的位置。根据模拟的结果

改进了浇注系统

调整浇注温度

优化了工艺方案

减少了缺陷的发生几率

进而改善了铸件的品质。结果表明

采用顶注式浇注系统

充型时间为13.4 s

浇注温度为1 550℃时

充型过程平稳

铸件缩松、缩孔缺陷得到了有效控制。

Abstract

Valve body isprone to shrinkage porosity

shrinkage and other defectsin the casting process. After three-dimensional modeling and meshing of the valve body parts

the filling and solidification process were simulated based on ProCAST software to predict the possible positions of shrinkage porosity

shrinkage cavity and other defects in the casting process. According to the simulation results

the gating system

pouring temperature

and process scheme was optimized to reduce the occurrence of defects

improving the casting quality. The results indicate that when the top gating system is used with filling time of 13.4 s and the pouring temperature controlled at 1 550 ℃

the filling process is stable

and the shrinkage defects are effectively controlled.
