| 摘要: |
| 本文通过实验提出了一种双相钢制绳线材的热处理工艺程序，即：奥氏体化及水淬以获得全部马氏体组织→临界间加热淬火以获双相组织并回火→酸洗磷化后多道次连续冷拔至终尺寸→入工时效。按此程序生产的线材σb可达1800MPa以上，且扭转、弯曲疲劳性能超过标准规定值。 |

| Abstract: |
| Based on the experiments，the heat treating technology process for the dual phase roping steel wire is suggested as follows： austenization and water quenching for full martensite structure→critical annealing and quenching for dual phase structure followed by tempering→after acid pickling and phosphorisation，continuous cold drawing multisteps until expected end dimension of the wire→artificial aging for stress relief.
According to the production process，the tensile strength of the wire may be achieved over 1800 MPa while the anti-torsion and bending fatique properties can exceed the value stipulated in the National Standard. |
