ZG310大型座体的铸造工艺设计及模拟优化

Casting process design and simulation optimization of ZG310 large seat body

以材质为ZG310的座体为研究对象并对其结构进行分析,以此设计了铸件的浇注系统、冒口等。首先采用Pro/E5.0软件进行三维建模;其次在Anycasting软件中对铸件成型过程进行了数值模拟仿真;最后对仿真结果进行分析,并预测座体凝固缺陷,对工艺进行相应优化。结果表明,采用开放式底部注入浇注系统,选择最终分型面和浇注方案,座体充型平稳有利于实现座体的顺序凝固;放置冷铁和增大冷铁的尺寸可以消除座体铸件的缩孔、缩松缺陷,对其实际生产起到了指导作用,从而保证了铸件的产品质量。

Taking the seat body made of ZG310 as the research object,the structure has been analyzed while the pouring system and riser of the casting have been designed.Firstly,Pro/E5.0 software has been used for three-dimensional modeling;secondly,the casting molding process has been numerically simulated in the Anycasting software;finally,the simulation results have been analyzed while the solidification defects of the seat body have been predicted to be analyzed and the process has been optimized accordingly.The results show that by using an open bottom injection pouring system,selecting the final parting surface and pouring plan,the seat body is filled with a stable shape which is beneficial to the realization of the sequential solidification of the seat body;placing cold iron and increasing the size of the cold iron can eliminate the shrinkage cavity and porosity defects problem of the seat body casting.It plays a guiding role in its actual production,thereby ensuring the product quality of the castings.
