一、前言铝稀土(La、Ce、Nd、R)中间合金,作为添加剂用于铝制造工业,能够提高铝制品的机械强度、耐腐蚀性、耐磨性和铝制品的成材率,其用量日见增加。但由于生产工艺等原因,铝稀土中间合金的价格较高,使合金的大量应用受到影响。因此,研究能大幅度降低中间合金成本的新工艺已成为迫切的问题。过去我所曾研究过在铝电解槽中加 I. INTRODUCTION Aluminum rare earth (La, Ce, Nd, R) master alloys are used as additives in the aluminum manufacturing industry to improve the mechanical strength, corrosion resistance, wear resistance and the finished product of aluminum products. See increase. However, due to the production process and other reasons, the price of aluminum rare earth alloy is high, so a large number of applications affected alloy. Therefore, the study of new processes that can significantly reduce the cost of master alloys has become an urgent issue. In the past I have studied in the aluminum cell plus
