摘　　要：针对电解铜阴极板导电杆钢包铜结构难以连接的问题,采用高频感应钎焊焊机,以Sn Cu0.7锡焊丝作为钎料进行了阴极板导电杆铜-钢异种金属的高频感应钎焊工艺研究。试验中采用Raytek FR1B红外测温系统实现对高频感应钎焊工艺温度的实时监测与控制,重点分析了高频感应钎焊工艺对导电杆钢包铜结构的质量及性能的影响,并观察分析了钎焊接头的微观组织和接头区域的成分。研究表明,以Sn Cu0.7锡焊丝作为钎料可以实现阴极板导电杆钢包铜结构的高频感应钎焊连接;获得的最佳工艺参数范围能够获得内外部质量、连接强度优良的接头;研究结果对进一步研究导电杆的导电性能及大批量生产阴极板导电杆具有重要意义。According to the welding problem of copper - steel which was used for the production of the permanent cathode plate conductive rod, taking SnCu0.7 tin wire as the solder, the high-frequency induction melt brazing process of permanent cathode plate conductive rod production was researched. Raytek FR1B infrared temperature measurement system was used in the experiment to monitor and control the temperature of the high frequency induction brazing process. The impacts of high-~equency induction melt brazing on quality and performance of permanent cathode plate conductive rod production were mainly analyzed, at the same time, the composition and microstructure of the joint region were observed and analyzed. The results show that the welding of copper and steel can be realized by high fi＇equency induction brazing of SnCu0. 7 solder wire, meanwhile, the optimum technological parameters obtained through this experiment can be used to control the welding quality and the connection strength of the welded joint. The research results are important to study the electric conductivity of the permanent cathode plate conductive rod and produce the permanent cathode plate conductive rod in the future.
