应用ViewCast软件对头部链轮体铸件进行充型及凝固过程模拟,预测到在铸件的轮缘和轮毂处易产生缩孔、缩松等铸造缺陷。通过对铸件结构分析,采取放置冒口和冷铁的工艺措施,消除了缩孔、缩松等缺陷。 Applying ViewCast software to simulate the process of filling and solidifying the head sprocket body castings, it is predicted that casting defects such as shrinkage cavities and shrinkage are likely to occur in the rim and hub of the castings. By analyzing the structure of castings, adopting the technological measures of placing riser and chill iron, the defects such as shrinkage cavity and shrinkage are eliminated.
