摘要：

球头挂环是输电线路中重要的连接金具，提高球头挂环的力学性能对输电线路安全运行十分重要。针对铁质金具高损耗、传统铝合金材料强度不足、现有高强度铝合金耐腐蚀性能差的问题，采用颗粒增强手段调整6082铝合金材料配方，并通过生产工艺参数优化，实现了材料与工艺的相匹配。结果表明，当锻前温度为520 ℃、固溶处理为535 ℃/1 h、时效处理为175 ℃/8 h时，高强度6082-A铝合金球头挂环的力学性能最佳，在该工艺参数下，采用固态模锻方式得到的高强度6082-A铝合金球头挂环的抗拉强度可达410 MPa，相比于6082铝合金球头挂环提高了22.5%，极大提升了铝合金球头挂环的承载能力，拓展了铝合金金具的应用场景。

The ball head hanging ring is an essential connection fittings in transmission lines, and it is important to improve the mechanical properties of ball head hanging ring for the safe operation of transmission lines. Therefore, aiming at the problems of high energy loss of iron fittings, the insufficient strength of traditional aluminum alloy and the poor corrosion resistance of existing high-strength aluminum alloy, the composition of 6082 aluminum alloy was modified by particle reinforcement method, and the matching of material and process was realized by the optimization of production process parameters. The results show that the ball head hanging ring of high-strength aluminum alloy 6082-A exhibits the best mechanical properties when the pre-forging temperature is 520 ℃, the solution treatment is conducted at 535 ℃ for 1 h, and the aging treatment is performed at 175 ℃ for 8 h. Under the above process parameters, the tensile strength of ball head hanging ring for high-strength aluminum alloy 6082-A can reach 410 MPa, which is 22.5% higher than that of ball head hanging ring for 6082 aluminum alloy, which significantly enhances the bearing capacity of ball head hanging ring for aluminum alloy and expands the application scope of aluminum alloy fittings.
