- 摘要:
- 针对压气机壳铝合金重力浇注铸件，依据孔洞缺陷的具体形态，对铸件表面或内部常出现的孔洞类缺陷进
行了观察、分析、归类，并对其形成机理进行了分析。 结合缺陷的产生机理和生产过程实际情况，从工艺和生产管理角度
提出了孔洞缺陷的预防控制措施。 结果表明，减少孔洞类缺陷的产生，从而保证铸件质量，节约生产成本。
In view of the gravity casting of aluminum alloy in the pressurized air casing, according to the specific morphology of the hole defects, the hole defects on the surface or inside of the casting were observed, analyzed and classified, and the formation mechanism was analyzed. Based on the mechanism of defects and the actual situation of the production process, the prevention and control measures of hole defects were put forward from the perspective of technology and production management. The results show that the casting quality can be guaranteed and the production cost can be saved by reducing the occurrence of hole defects.
