摘　　要：对连铸连轧法生产的20mm铜银合金杆坯,通过拉拔机连续拉拔成型生产铜银合金接触线。检测结果表明:产品与相同规格的纯铜线坯比较,抗拉强度明显提高,在电阻率等方面均达到新的铁标要求。This paper describes the application of continuous drawing to produce Cu-Ag alloy contact wire from Cu-Ag alloy rod of Ф20 mm that produced by continuous casting and rolling. Test result indicates that the tensile strength has markedly improved compared with the same specifications of pure copper wire billet. Of all the performances such as resistivity are meet the new railway requirements standards.
