摘　　要：铜银合金电车线平直度差、强度低的主要原因是连铸时的晶粒粗大、含银量不均匀所致。细化晶粒、均匀含银量是解决该问题的关键。通过高温熔炼。Coarse grain and un-homogenous Ag content during continuous casting lead to poor flatness and low strength of Cu-Ag alloy tramcar touching wire, so the grain should be fined and Ag content should be unifonninged. The comprehensive performance of the tramcar touching wire could be improved through smelting at high temperature, drawing pole at low temperature and raising the liquid alloy storage in crystallizer bottom.
