摘　　要：介绍了Al-2.2Cu-1.5Mg-1.0Fe-1.0Ni高纯铝合金熔炼和铸造工艺过程。熔炼工艺采取精练剂精炼和单转子氩气精炼6min,静止25min,金属液经过30ppi和50ppi的陶瓷过滤片过滤。铸造工艺中针对该合金不同规格的铸锭,确定了浇注温度、铸造速度、冷却速度等工艺参数。金相组织观察表明,冶金质量良好。The process on smelting and casting of high purity aluminum alloy of AI-2.2Cu-1.5Mg-1.0 Fe-1.0Ni was introduced. During smelting study stage, refine agent and single-rotor with argon refine was applicatied and double ceramic plate filtering was utilited. Casting temperature, casting velocity, intensity of cooling was optimizated according to different specifications. The microstructure observation results show that metallurgy quality is excellent.
