美国麻省理工学院的研究人员通过研究铝合金的硬化过程,提出了一种使用喷嘴在铸件中产生更均匀铜和锰分布的方法。直接冷却铸造铝合金是通过将熔融金属浇注到冷却模具中使其快速冷却成为铝合金铸锭的半连续工艺,这种工艺在质量控制方面存在问题,因为铸锭中的铜或锰的分布不均匀,可能会导致铸造出来的铝合金凝固板坯或者铝合金铸锭中心附近缺少合金元素,出现质量问题。研究人员在直接冷却铸造铝合 Researchers at the Massachusetts Institute of Technology (MIT) have come up with a way to create a more uniform distribution of copper and manganese in the casting using nozzles by studying the hardening process of the aluminum alloy. Direct cooling of a cast aluminum alloy is a semi-continuous process of casting a molten metal into a cooling mold to rapidly cool it into an aluminum alloy ingot which has a problem of quality control because the distribution of copper or manganese in the ingot is not Uniform, may result in the casting of solidified aluminum slab or aluminum alloy ingot near the lack of alloying elements, quality problems.
