摘要
简要地叙述了铝合金消失模生产试验中常见的铸造缺陷,如渗漏、针孔、气孔、冷隔、铸件变形、球粒状表面、粘砂及充型不足等,分别对其成因进行了分析,并提出了相应的解决方法。
Difficulty in ellminating the defects in EPC aluminum alloy parts resuted from very complicated processing inhibited the development of EPC aluminum alloy at home.Origination of common defects in EPC aluminum alloy was described,including cold shut,inclusion,deformation,and so on,and countermeasures were proposed,such as controlling pouring temperature and melting quality,using rational filling velocity,and so on.
