Magnesium alloy melt modification techniques Cade Dongguan Sheng magnesium alloy melting magnesium alloy material deterioration aim is to change the organizational form of magnesium alloy, the process of grain size and mechanical properties of the alloy has a greater impact magnesium alloy die-casting, and liquid magnesium oxide inclusions have a certain influence. The study shows that without Al magnesium alloy magnesium alloy die Dongguan, using zirconium modification has good grain refinement effect principle is Zr peritectic reaction occurs, and promote grain refinement. After the addition of a suitable carbon material in Mg-Al alloys, and it generates A1C4 Dongguan magnesium alloy die casting parts and alloy liquid from a chemical reaction, the compound can play a major role in foreign nuclei magnesium alloy die-casting factory in Dongguan, prompting grain refinement of magnesium alloys. Add mixed rare earth based on different levels of AZ91 magnesium alloy on its organization and properties of cast and solution and aging also have a significant effect. Dongguan Sheng Cade retardant magnesium alloy magnesium alloy magnesium alloy oxidation prone to severe burning in the melting casting process. Practice has proved that the flux Protection Act and SF6, SO2, CO2, Ar gases such as fire protection law is effective method, but they will have serious environmental pollution in the application and makes the alloy performance degradation, increased investment in equipment. Dongguan magnesium alloy die-casting, Cade Sheng (certified), magnesium alloy die by Cade Sheng Technology Co., Ltd. of Dongguan City. Sheng Technology Co., Ltd., Dongguan City, Cade (www.kadesn.com) is Dongguan, the other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
