| 摘 要： | 通过研究规格为φ14mm的20MnSi热轧棒材工艺参数，指出在终轧温度为850℃左右时，以0．5～2．0℃／s的速度冷却至650℃，得到的20MnSi热轧成品棒材组织晶粒更细小，力学性能更高。与常规轧制相比，对20MnSi热轧棒材参数进行控制，抗拉强度提高60MPa，晶粒直径平均缩小2．2μm。

| Abstract: | Technological parameter of the 20MnSi hot-rolled bar（the specification： 14 mm） after the research indicates that 20MnSi grain size is smaller and the mechanical property is higher when finish rolling temperature is at 850 ℃ or so, cooling to 650 ℃ at 0.5-2.0 ℃/s. Compared with the routine rolling, the tensile strength is enhanced by 60 MPa, average grain diameter reduction is 2.2 μm, when 20MnSi hot rolled bar process are controlled. |
