制订了轴承瓦体的传统铸造工艺方案,然后利用Viewcast软件对该方案数值模拟。结果显示:铸件两侧及其环形部分较薄区域最先凝固,内腔上下部和筋贯穿部位最后凝固,导致产生缩松、缩孔等缺陷;为此,在铸件相应位置设置两个压边冒口和一个侧冒口,但仍难以消除缩松、缩孔等缺陷,之后增设冷铁,获得了合格铸件。 Developed a traditional casting process of bearing tile body, and then used numerical simulation of Viewcast software. The results show that the two sides of the casting and its annular portion are the first to be solidified, and the upper and lower parts of the lumen and the rib penetrate finally to be solidified, resulting in defects such as shrinkage and shrinkage. To this end, two blankets Riser and a riser, but still difficult to eliminate shrinkage, shrinkage and other defects, after the addition of cold iron, access to qualified castings.
