运用传统的铸造工艺设计方法对铸钢件受力端盖的铸造工艺进行了初步设计,利用ViewCast模拟软件对受力端盖的凝固过程进行了模拟。结果显示,在受力端盖壁厚大处会产生缩孔、缩松缺陷。通过增加冒口尺寸和改变分型面位置的方法,最大程度地消除了铸造缺陷,从而获得了合理的铸造工艺方案。 The casting process of cast steel end caps was preliminarily designed by using the traditional casting process design method. The solidification process of the end caps was simulated by ViewCast simulation software. The results show that the wall thickness in the end cap will produce shrinkage, shrinkage defects. By increasing the riser size and changing the position of the parting surface, casting defects are eliminated to a maximum extent, and a reasonable casting process scheme is obtained.
