摘　　要：根据轧制理论,轧制过程中在较大温度梯度条件下,中心区域更容易变形,奥氏体组织更加细小,从而改善钢材组织和力学性能。According to the rolling theory,the central area is easier to deform and the austenite structure is finer under the condition of larger temperature gradient in the rolling process,thereby improving the structure and mechanical properties of the steel.
