- 摘要:
- 对于铝合金倾转金属型重力铸造而言,由于分型的局限性,在非分型面处易出现厚大热节,得不到有效补缩而出现废品;以高压开关壳体铸件为例,通过模拟分析,探讨了缩松形成原因。结果表明,通过在孤立热节处增加水平侧冒口,解决了缩松缺陷。
Due to the limitation of parting,the thick hot spot was easy to appear at the non-parting surface,and the waste products would appear because of the lack of effective feeding.Taking high voltage switch shell casting as an example,the causes of shrinkage and looseness were discussed through simulation analysis.The results show that the shrinkage defect can be solved by adding horizontal riser at isolated hot joint.
