摘　　要：针对含银铜排产品,进行了产品及连续挤压成形工艺分析和模具设计,并完成了模具制造和生产实验研究,对产品的组织进行了分析,检验了产品的含银量、屈服强度、电阻率、延伸率等性能。结果表明,采用连续挤压代替"轧制-拉拔-退火"工艺,效率更高,上引法生产的含银铜杆经过挤压后,晶粒得到细化,基体组织中形成富集银元素的白色弥散颗粒,产品的基本性能达到开发要求。In this paper ,continuous extrusion process of Cu - Ag alloy busbar product is analyzed and also the mould design. The mould manufacture and production experiment research are presented, the organization of product is analyzed, furthermore, the products silver content ,yield st rength, resistivity,elongation rate a re tes ted . The results show that theefficiency of continuous extrusion process is higher than the process of rolling - drawing - annealing. The grain of Cu - Ag alloy rod with upcasting approach is refined after continuous extrusion process, white dispersion particle contanining silver elements is formed in the matrix,the basic performance of the products can meet the development requirements.
