Abstract
本发明涉及金属材料处理技术领域，公开了一种适用于钢帘线结构的极高强钢丝制备方法。首先制备表层镀黄铜索氏体钢丝；其次对制备得到的1.3mm‑1.8mm的索氏体钢丝进行轧制，最终得到扁状索氏体镀铜钢丝；最后对轧制的钢丝经过23+3道次的拉拔，最终制备出直径为0.15mm‑0.40mm的极高强（MT）索氏体钢丝。与现有技术相比，本发明在拉拔前引入轧制手段，通过预轧制‑多道次拉拔复合变形技术细化钢丝内部组织晶粒，在钢丝变形过程中，细化晶粒产生的细晶强化与加工硬化协同作用，可使钢丝强度进一步提升，并且在拉拔变形过程中更加协调，同时减少拉拔过程中的热聚集，从而提升钢丝稳定性以及力学性能，并且该技术极易实现产业化。
