高强不锈钢丝试验研究

Experimental Study on High-strength Stainless Steel Wires

通过分析传统拉吊索存在的病害原因及其改进措施的不足,提出了将不锈钢丝应用于拉吊索的思路。提出了用于拉吊索高强不锈钢丝的强度、断裂延伸率等技术指标的目标要求。选择适合的不锈钢反复进行了力学和工艺性能试验。通过试炼得到了高强、高延性的不锈钢,并继续进行了力学及工艺性能试验,最终得到了符合桥梁拉吊索用的高强不锈钢丝,并提出了下一步的研发方向。

By analyzing disease causes of traditional suspender cables and lack of the improvement measures, the idea of applying stainless steel wires to suspender cables is put forward. The objectives and requirements of technical indicators of high-strength stainless steel wires for suspender cables such as strength, elongation at fracture, etc. are proposed. The repeated mechanical and processing property tests of selected appropriate stainless steel are conducted, and the stainless steel with high strength and high ductility is obtained by trial refining. Then, the mechanics and processing property tests are continuously conducted, the high strength stainless steel wires suitable for bridge suspender cables are obtained at last, and the next stage research and development direction is put forward.
