摘　　要：对镁合金水玻璃砂型阻燃效果进行了实验性研究。结果表明,面砂中未加阻燃剂时,试棒表面氧化严重;加入阻燃剂时,试棒表面光洁。根据现在的镁合金铸造工艺技术,已能浇注表面无氧化铸件,且各项性能符合要求,可以实现镁合金的砂型铸件的小批量生产。The flame retardant effect of the sodium silicate mold of magnesium alloy was studied experimentally. The results show that the specimen surface is oxidized without adding the flame retardant in surface-sand; the specimen surface is bright and clean with the flame retardant in surface-sand. According to now magnesium alloy casting technology, the castings with non oxidation surface can be cast, and various properties meet the requirements, which can realize small batch production of sand castings of magnesium alloy.
