摘　　要：研究了控轧工艺参数对37Mn5钢(N80石油套管)组织和性能的影响,进而研究高温形变淬火—回火与轧后在线控制冷却(余热处理)工艺对组织和性能的影响。研究结果表明:高温形变淬火—回火钢的强度比普通调质工艺提高1～2个级别;在线控制冷却可获得全部索氏体,性能与API标准N80合格值相当。This paper studies the influence of technologic parameters controlling roll on structure and property of 37Mn5 Steel. Furthermore, the effects of high temperature thermomechanical tempering treatment and line-controll cooling (residual heat treatment) technology on structure and property of 37Mn5 Steel are researched. The results show that strength of the steel after high temperature thermomeehanical tempering treatmant increases by 1-2 grade to the steel after common hardening and fempering. The whole quenched Sorbite can be obtained by line-control cooling and Its propertiy statisties qualified N80 value of API standard.
