| Abstract: | The paper presents the application of finite difference method to establish the temperature model of bar rolling process.Based on the simulation calculation of rolling process,high pressure water descaling and air cooling,obtain the distribution rule of external and internal temperature of rolling piece head and tail ends.The temperature field of simulation calculation for a certain bar rolling plant with this program is proven that the calculated value is basically coincided with the actual value.Therefore,the paper analyses the regularities of temperature change during bar rolling process. |
