摘要
通过常规铸造A356合金锭与电磁搅拌+水冷热顶铸造A356合金棒的质量差异的对比,分析电磁搅拌+水冷热顶铸造对铝合金棒组织性能的影响,结果表明采用电磁搅拌+水冷热顶铸造方法生产出的A356铝合金棒的质量在各个方面均优于常规铸造A356合金锭的。
Compare the quality of A356 alloy which are made between common casting technology and electromagnetic stirring ＋ Hot pot billet casting technology, are introduced in this paper, the influences of electromagnetic stirring ＋ Hot pot billet casting technology on the structure and behaviors surface quality are analyzed. It was shown that the A356 alloy bar were made by electro- magnetic stirring ＋ Hot pot billet casting technology is better than the A356 alloy ingot were made by common casting technology on quality.
