随着镁合金应用技术的不断提高,镁及镁合金在各个行业的用量日益增大,废镁和废旧镁合金的回收与利用产生了巨大的需求空间,镁合金的循环利用具有重要意义,已经成为突出课题。镁合金的熔化潜热比铝合金低得多,比铝合金消耗的能量少,因而镁及其合金是易于回收的金属,目前使用的镁合金均可以回收。一方面是回收失效或报废的镁合金零部件,另一方面是回收镁在生产过程中的废料和切屑。
With the increasing application of magnesium alloy technology, magnesium and magnesium alloy in an increasing amount of various industries, waste magnesium and scrap magnesium alloy recycling and utilization of a huge demand for space, recycling of magnesium alloys is of great significance, has been Become a prominent issue. Magnesium alloys have a much lower latent heat of melting than aluminum and consume less energy than aluminum so magnesium and its alloys are easily recyclable metals that are currently being recycled. On the one hand is the recovery of invalid or scrap magnesium alloy parts, on the other hand is the recovery of magnesium in the production process of waste and chips.
