摘　　要：针对盘条在后续拉拔、捻制过程中出现的接头断裂频繁问题,研究了高碳钢SWRH82BCr盘条在电阻对焊后的高温回火工艺过程。结果表明,回火温度影响二次相碳化物的析出,T_(max)=850℃时82BCr焊接接头综合力学性能较好,且材料接头处韧性与母材趋于一致。The steel wire rods in drawing and twisting joints in the manufacturing process of the fracture problem of frequent, high temperature tempering process of high carbon steel wire rod SWRH82BCr after resistance welding. Results showing, the tempering temperature affects the precipitation of two phase carbides, and the mechanical properties of 82BCr joints are higher when Tmax = 850℃ , and the toughness at the joint is consistent with the base material.
