  • 消失模铝铸件针孔形成机理研究

    发布日期:2019-08-06 发布者:润恒压铸

    干砂消失模铸造被誉为21世纪的铸造技术,其成形理论不同于传统的空腔铸造。但用该工艺生产的铝铸件的针 孔问题是困扰世界铸造界的一大难题。针对铝合金消失模铸造浇注温度高、铸型冷却慢的特点,探讨了高温铝液(760~800℃)的变质、晶粒细化、以及浇注温度、聚苯乙烯泡沫塑料模样等对铝件针 孔的影响,并与树脂砂空腔铸造进行了比较,阐述了干砂消失模铝铸件针 孔形成的特殊性。

    铸铝件在工业生产和日常生活中有广泛的应用,其硬度大、质量轻的优点使其成为了的工业材料和生活必备用品,但是大型铸铝件的铸造极为困难,需要严格的工艺控制,常见的大型铸铝件按形状可分为套类、板类、环类、箱体类、帽类等,不同形状的大型铸铝件铸造工艺要求各不相同,比如套类需要强化内芯的退让性,以保证成品的厚度、比如板类需要增加拉筋来避免变形;比如薄板的浇筑快速成型等等。针对大型铸铝件的铸造工艺进行研究,有助于提高工艺水平,提高我国大型铸铝件的成品质量,为工业发展提供的原料。
