Production processes of magnesium alloy mainly include smelting and foundry. In these processes, magnesium alloy may easily react with oxygen and oxygen-containing compounds releasing enormous energy even bringing on explosion causing great loss of lives and properties. 镁合金生产的主要工艺是熔炼、铸造,熔炼、铸造时,镁合金极易与氧及含氧化合物反生氧化反应,释放出巨大的热量,发生爆炸事故,使生命和财产受到巨大损失。
