摘    要：针对现有工艺设备,以20MnSi坯料为母材,通过调整化学成分,修改精轧孔型设计参数,采用控制轧制和控制冷却工艺,成功地生产铁素体晶粒尺寸在5～10μm的400 MPa级细晶粒钢筋。

Abstract: According to conditions of product line,the 400MPa fine grained steel rebar of 20MnSi with ferrite grain size of 5-10μm was successfully developed by adjusting the chemical compositions and new design of deformation parameters of finite roll pass by using new process with controlled rolling and cooling techniques.
