摘　　要：为了研究Na元素对6A02合金φ482规格熔铸工艺影响,采用两种实际生产工艺流程对所生产的6A02合金铸锭进行质量分析。通过对比研究,观察两种工艺流程中Na元素对6A02合金铸锭在成分偏析、微观组织及力学性能等方面的影响,并确定适合生产的工艺流程。In order to research the effect of Na on melting & casting process of 6A02 alloy withφ482mm, two technological processes were applied. The quality analysis of two different 6A02 alloys was implemented. Through comparative study, the influence of Na on component segregation, microstructure and mechanical properties existing in 6A02 alloy were observed. In the meantime, the suitable production technological process was determined.
