摘　　要：采用熔剂氧化精炼法进行废紫杂铜除铁技术研究,并对材料的性能进行了检测。结果表明:随着保温时间的延长,除铁效果越好。随着铁含量的降低,晶界数量越多,导电率提高,但是硬度下降。精炼温度1150℃,3#熔剂配方除铁效果最好,初始含铁量0.49wt%的紫杂铜实际除铁限度为0.005wt%。The flux oxidizing refining method was used to study the removal of iron from impure copper.The material performance was tested.The results show that with the prolongation of holding time,the effect of iron removal is better.With the decrease of iron content,the amount of grain boundary is larger,the electric conductivity increases,but the hardness decreases.When the refining temperature is 1150℃,the 3# flux formulation is the best.The initial iron content of impure copper is 0.49wt%,and the actual iron removal limit of impure copper is 0.005wt%.
