| Abstract: | The temperature field of round steel circular seam swirl during controlled cooling was simulated by using ANSYS FE analysis software in this paper.And a predicated model of temperature field is presented for controlled cooling of round steel.The heat transfer boundary condition is studied,the distribution and change of temperature field in circular seam swirl two-stage controlled cooling process in four different project were analyzed.Results showed that grain size thinner than the rounds＇ conventional water cooling,and the characteristics of temperature and microstructure changes were analysed.The predicated model simulation results of the temperature field during cooling processing were matched well.The analysis results are helpful to understand the cooling laws of round steel,to guide the practical process in round steel as well as to develop control cooling technologies for round steel production. |
