| Abstract: | The FEM model of hot ring rolling process has been simulated.Through the simulation,the rules of velocity field deformation area distribution and metal flow have been obtained.The influence rule of mandrel roller feeding speed and driven roller angular speed to the rolling speed has been put forward.It provides reference to make rational rolling process and improve the rolling accuracy. |
