【摘要】 随着铝资源的减少,废铝再生技术越来越受重视。本文实验研究了熔剂配比、熔剂加入量和熔炼温度等对铸造废铝屑的回收率、合金含杂量的影响。通过正交优化和比较等方法得到了最优的熔剂配比及净化处理工艺:配方③熔剂、熔炼温度720℃、熔剂加入量4％的组合,在此条件下废铝屑的回收率为90 ％,合金的含杂量为0．0531％。更多还原

【Abstract】 With decreasing of Al resource, the emphasis on reprocess of Al scrap is increasing. In this paper, the effect of flux components, flux addition and melting temperature on recovery ratio and impurity content was analyzed. The results showed that the optimized parameters of purification process for scraps from casting Al alloys was combination of flux components (3) ,melting temperature of 720℃ and flux addition of 4%. Recovery ratio was 90% and impurity content was 0.0531% in the combination.更多还原
