壳芯较普通砂芯具有许多优点,因此在黑色金属铸造上已经被广泛应用。壳芯在镁合金铸造上应用具有同样价值,但因镁合金在高温下易燃烧,故需解决防氧化等一系列特殊问题,因而限制了壳芯在镁合金铸件生产上的应用。我厂经过反复试验,解决了防氧化燃烧等工艺问题。但是我厂镁铸件的芯子尺寸大、形 Shell core has many advantages over ordinary sand core, so it has been widely used in ferrous metal casting. Shell core application in magnesium alloy casting has the same value, but because of magnesium alloy flammable at high temperatures, it is necessary to solve a series of special problems such as oxidation prevention, thus limiting the shell core in magnesium alloy casting production applications. I plant after repeated tests to solve the anti-oxidation combustion process issues. But my factory magnesium casting core size, shape
