- 摘要:
- 为提高涡轮增压器壳体生产效率及品质,通过添加冒口及补贴设计了1箱1件的铸造工艺,并在此基础上设计了1箱4件的铸造工艺。结果表明,最终的1箱4件铸造工艺基本消除铸件缩松,同时实现了铸件最大体收缩的孔隙率小于0.58%,并且成功地把残余缩松控制在非重要面内。对于壳体等复杂铝合金薄壁小件,通过合理的设置补贴及调整,冒口可以有效消除铸件的缩松缺陷。
In order to improve the production efficiency and quality of turbocharger housing,the casting process of 1 box and 1 piece was designed by adding risers and subsidies,and the casting process of 1 box and 4 pieces was designed on this basis.The results show that the final casting process of 1 box 4 pieces basically eliminates the shrinkage porosity of the castings,achieves the maximum shrinkage porosity of the castings less than 0.58%,and successfully controls the residual shrinkage porosity in the non-important plane.For the complex thin-walled aluminum alloy parts such as turbocharger housing,the rising can effectively eliminate the shrinkage porosity defect by reasonable setting subsidy and adjustment.
