摘要

钢丝绳索具在机械、桥梁和起重设备中扮演着关键角色，其可靠性主要取决于钢丝绳末端与接头的钎焊质量。传统的ZnCu6钎料在钎焊过程中存在温度过高导致钢丝软化和强度降低的问题，同时低温下钎料流动性差，难以实现良好的填充，影响接头强度。鉴于此，在不影响接头强度的前提下适当降低所用钎料的熔点成为一个可行的研究方向。文中在ZnCu1.7共晶合金的基础上添加稀土元素Yb来细化晶粒，配合适量Ag组元改善钎焊接头的强度，研发出一种新型钢丝绳接头钎焊用ZnAg2Cu1.7Yb钎料，并通过熔点测试、机械性能测试、晶粒度分析、流动性和孔隙率测试等方法，对ZnAg2Cu1.7Yb钎料进行了性能表征。试验结果表明，新型钎料的钎焊温度比ZnCu6低80 ℃，有效减少了对钢丝绳的热影响，同时接头强度提高了9.5%；此外，ZnAg2Cu1.7Yb钎料的晶粒得到细化，流动性增强，接头内部孔隙率显著降低。

Abstract

Wire rope rigging plays a crucial role in machinery

bridges

and lifting equipment

and its reliability mainly depends on the brazing quality of the wire rope ends and joints. The traditional ZnCu6 brazing material has issues such as high temperature during the brazing process leading to the softening and strength reduction of the steel wires

while at low temperatures

the poor fluidity of the brazing material makes it difficult to achieve good filling

affecting the joint strength. In light of this

appropriately reducing the melting point of the brazing material used without affecting the joint strength has become a feasible direction for research. This paper adds the rare earth element Yb to the ZnCu1.7 eutectic alloy to refine the grains

and improves the strength of the brazed joint with an appropriate amount of Ag component

developing a new type of ZnAg2Cu1.7Yb brazing material for wire rope joint brazing

and the performance characterization of ZnAg2Cu1.7Yb brazing material was carried out through methods such as melting point testing

mechanical property testing

grain size analysis

flowability and porosity testing. The experimental results show that the brazing temperature of the new brazing material is 80 ℃ lower than that of ZnCu6

effectively reducing the thermal impact on the wire rope

while the joint strength is increased by 9.5%; in addition

the grains of the ZnAg2Cu1.7Yb brazing material are refined

the fluidity is enhanced

and the porosity inside the joint is significantly reduced.
