摘　　要：建立了六角中空钢轧制过程的三维塑性变形模型,定量计算了中空钢轧制过程的速度场、应变场、应力场;建立了中空钢轧制过程的微观组织演变模型,得到了主要工艺参数轧制速度对微观组织演变的影响规律。In this paper the 3D model for simulating the roiling process of hexagon driUing steels was build. Velocity field, strain field, stress field and temperature field were calculated. The microstructure evolution models of the deforming process were set up. The influence law of grain size by rolling velocity was researched.
