| 摘 要： | 根据热轧生产过程中轧辊的实际边界条件,借助于有限元软件ANSYS建立了高速钢和高铬铸铁热轧辊温度场的数值计算模型,对其工作时的温度场进行了对比分析。结果表明:模型的计算结果与现场下机后辊面温度的实测数据比较吻合;在相同的轧制参数和冷却参数条件下,下机后高速钢轧辊表面温度高于高铬铸铁轧辊的;由于高速钢轧辊的导热率及摩擦因数较高铬铸铁的大,使其旋转一周后达到的最高温度较高铬铸铁轧辊的高65℃左右,达到582.5℃;结合现场的情况,优化了高速钢轧辊的冷却参数,可使其下机后的温度保持在65℃以下。

| Abstract: | According to the actual boundary condition of work roll in hot rolling strip production,a mathematical model for numerical simulating the temperature field of high speed steel(HSS) and high-Cr work roll was established with ANSYS finite element software,and the surface temperature fields between them were compared.The results show that the calculated values were in good agreement with the measured data of roll surface temperature after rolling.With the same parameters of rolling and cooling system,it was fo... |
