摘要

利用华铸CAE软件对大型挂舵臂铸钢件进行凝固过程的数值模拟

揭示了铸件产生缩松、缩孔的部位和形成原因。模拟结果表明:通过优化铸造工艺

合理设置冒口、冷铁

可以保证铸件的顺序凝固和金属液的有效补缩

获得结构完整、没有缺陷的铸件。

Abstract

The origination and location of shrinkage porosity（hole）in the rudder horn was described by simulating the filling process of large pelagic cast-steel rudder horn using a CAE software.The complete structure with defects-free can be realized by optimizing process and rationally assembling riser and chill to ensure the directional solidification and effective feeding of melt.
