利用废旧紫铜生产上引铸造无氧铜杆的研究

Investigation into the production of upcast OF copper rods from copper scraps

在上引铸造无氧铜杆的生产中,为了提高废旧紫铜的利用率,采用稀土盐、稀土铜中间合金作为精炼剂,分析了各种精炼剂对无氧铜杆电阻率和显微组织的影响。结果表明:添加50%的废旧紫铜,采用稀土盐和稀土铜中间合金复合精炼,所生产出来的无氧铜杆的电导率和显微组织都比较好。

In order to increase the utilization ratio of copper scraps during the production of upcast OF copper rods, investigation was made into the affection of refining agents on the conductivity and microstructure of OF copper rods using intermetallic alloys of rare earth salt and rare earth copper. The result showed that the OF copper rods produced by using the intermetallic alloys of rare earth salt and rare earth copper as (compo-)(site) refining agent and adding 50% copper scraps have higher conductivity and better micro-structure.
