摘　　要：对目前生产夹渣出现频次高的几种合金进行分析,以确定其产生的原因,并提出相应的改进措施。经过分析发现,7xxx合金材料中夹渣低倍显示该缺陷为金属间化合物;2xxx合金材料夹渣为非金属夹渣。In this paper, several alloys with high frequency of slag inclusion are analyzed to determine the causes and put forward corresponding improvement measures. After analysis, it is found that the slag inclusion in 7xxx alloy material shows that the defect is intermetallic compound. 2xxx alloy material slag inclusion is non-metallic slag.

关 键 词：7xxx合金 2xxx合金 夹渣 分析
