The invention provides a corrosion-resistant high-strength steel wire production process which comprises the following steps of S1, preparing a high-strength steel wire; S2, preparing polyether-ether-ketone mixed liquor; S3, soaking the high-strength steel wire prepared in the S1 into the polyether-ether-ketone mixed liquor prepared in the S2, heating to 400 DEG C, and then keeping warm for 2 to 3h; S4, putting the treated high-strength steel wire in an air circulation cooling environment, and quickly cooling to the normal temperature by utilizing air. The corrosion-resistant high-strength steel wire prepared through the process can last for more than 15000h in a neutral salt spray resistance test, and can resist corrosion for 100 to 120 years under the atmospheric environment. The high-strength steel wire can realize super-long-acting chemical corrosion resistance, high temperature resistance, radiation resistance, delamination resistance and hydrolysis resistance, can be well appliedto the manufacturing of steel pulling cables, suspender ropes and tie bar ropes for extra-large bridges, suspension bridge slings and cables for special structures, and can be applied to the manufacturing of other steel wire ropes.
本发明提供了一种耐腐蚀的高强钢丝的生产工艺，以下步骤：以下步骤：S1.制备高强度钢丝；S2.制备聚醚醚酮混合液；S3.将S1制得的高强度钢丝浸泡于S2制得的聚醚醚酮混合液中，加热至400℃后保温2‑3h；S4.将处理后的高强度钢丝置于空气循环冷却环境中，利用空气快速冷却至常温。通过本工艺制得的耐腐蚀的高强钢丝耐中性盐雾实验15000h以上，可满足大气环境100～120年防腐寿命。能超长效的耐化学腐蚀、耐高温、耐辐射、耐剥离性、耐水解性，能很好地应用于特大型桥梁的钢拉索、吊杆索，系杆索，悬索桥吊索及特殊结构用索的制作，也可以用其它钢丝绳索的制作。
