摘要
介绍了稀土银铜合金导线的生产工艺,重点介绍了稀土的添加方法和分析了稀土的作用。在铜熔体中加入微量稀土元素,稀土能对铜银合金熔体中的氧、硫有较强的脱除能力,使铜熔体得到净化。同时,稀土的加入还能减少铸造过程中铜银合金线杆的表面裂纹缺陷和细化晶粒。从而,使铜银合金导线的各种性能得到很大程度的改善和提高,即稀土的加入使铜银合金线杆的延伸率、抗拉强度、导电率均得到提高。
The process of Cu-Ag contact wire with adding rare-earth elements was presented. The additive process of the rare-earth elements and the function of the rare-earth were chiefly analyzed. Adding the rare-earth elements into melt alloy, the oxygen and sulfur can be removed from the melt, so we can get the purified alloy. At the same time, adding rare-earth can reduce the external crack flaws which produced during the casting and make the grain refined, as a resuit, the properties of the Cu-Ag alloy contact wire can be greatly improved and meliorated. Such as the conductivity, the specific elongation and the tensile strength are all improved.
