| 摘 要： | 对A356.2铝合金锭、熔炼炉中熔体、浇包中熔体以及低压铸造机保温炉中熔体的锶含量进行了对比分析,研究了锶元素在A356.2铝合金熔炼过程中的烧损情况。结果表明,A356.2铝合金中锶在熔炼过程中烧损程度较大,在低压铸造机保温炉中的烧损比熔炼过程中的锶烧损要少,为达到工艺要求可在精炼除气前添加铝-锶合金来调整锶含量。

| Abstract: | Sr content in A356.2 aluminum alloy ingot, in melt in smelting furnace and ladle as well as in melt in holding furnace of low pressure die casting was analyzed comparatively to understand the burning-loss of Sr in A356.2 aluminum alloy during melting process. The results show that there exists serious Sr burning-loss in A356.2 aluminum alloy during melting process, and Sr burning-loss in melt in holding furnace of low pressure die casting is lower than that during melting process. Sr content in the Al alloy... |
