摘　　要：为了国产化某型机车牵引电机鼠笼式转子端环和导条钎焊用高温钎料和钎剂,使用综合热分析仪分析了进口钎料和国产钎料的熔化区间,使用高温润湿炉分析了不同钎剂的流铺性和钎料的润湿性,然后进行了电机转子端环和导条中频感应钎焊试验验证,并进行了钎焊接头的拉伸性能测试。最终确定采用国产钎料BAg30CuZn替代进口钎料BAg-20,用国产钎剂QJ109替代进口钎剂FB3-G,可以满足工艺和设计要求,实现了国产化。In order to localize high-temperature bra zing filler material and flux for brazing of a locomotive traction motor squirrel-cage rotor end ring and conducting bar,the melting range of the imported and domestic brazing fillers was analyzed by using comprehensive thermal analyzer,the spreadability of different fluxes and wetting behavior of the brazing fillers were analyzed by using high temperature wetting furnace.The medium frequency induction brazing test verification of the end ring and conducting bar was carried out,and the tensile properties of the brazing joints were tested.It is determined that the domestic filler metal BAg30CuZn is used to replace the imported filler metal BAg-20 and the domestic brazing flux QJ109 is used to replace the imported brazing flux FB3-G,which can meet the technological and design requirements,and realizes the localization.
