摘　　要：分析比较了稀土、AlTiC,AlTiB三种铝细化剂各自的制作方法、性能特点,并进一步阐述了它们细化纯铝的机理和存在的问题,由此提出了一条更为有效的、利用复合细化剂进行纯铝细化的新方法。In the paper three kinds of Al grain refiner including RE, AlTiC and AlTiB were compared through analyzing their manufacturing methods and characteristics. The mechanism and the problems of their refining Al were also discussed. A new effective way of refining Al by using compounded grain finer was put forward.
