单件小批铝合金薄壁壳体件失模精密铸造技术研究

Study on The Technology of Lost-Pattern Precision Casting for Single or Small Scall Production of Thin-Walled Al Alloy Parts

本文针对导弹研制生产对铸造的要求,提出了一种适合于单件、小批铝合金薄壁壳体件的失模精密铸造新工艺,并进行了系统研究和样件试浇。

Respecting the requirement of missile development for cas-ting technology, a new kind of lost-pattern precision casting technologyfitting for single or small scale production of thin-wall Al-alloy parts wasput forward and studied systematically. By means of this technology,sample castings were successfully obtained.
