综述了国内外在压铸过程中所采用的阻燃方法。在这些阻燃方法中 ,添加合金元素法对镁合金阻燃具有明显作用 ,富Ce稀土的添加同样对镁合金的阻燃具有显著作用。试验结果表明富Ce稀土的添加可使镁合金起燃温度提高 70℃。认为中国镁合金防燃的重点应放在普通冷室压铸机条件下通过添加稀土加以解决
The fire-retardant methods used in the die-casting process at home and abroad are summarized. In these flame-retardant methods, the addition of alloying elements has a significant effect on the flame retardancy of magnesium alloys. The addition of Ce-rich rare earths also has a significant effect on the flame retardancy of magnesium alloys. The experimental results show that the addition of Ce-rich rare earth can increase the ignition temperature of magnesium alloy by 70 ℃. That the focus of China’s magnesium alloy should be placed on the common cold chamber die casting machine conditions by adding rare earth to be resolved
