摘　　要： 考虑高温金属的辐射散热、轧件内部的热传导、金属变形及塑性变形产生的热量，用二维有限元法求解了热轧过程中，钢轨的温降和横断面上温度场．计算表明，钢轨同一横断面上温差值达１００℃以上．计算值与实测轧件表面温反基本相符． By considering radiation heat losses of hot metal,heat conduction in rail stock,metal deformation and generation of heat by deformation,a two-dimensional FEM is used to calcuate temperature drops and temperature field of rail stock during hot rolling. It is found from the finite element analysis that the temperature difference in cross section of rail stock is at least 100 ℃ or more. The comparison between theoretical prediction and experimental results on the surface temperature of rail stock shows that there is reasonable agreement between practice and theory.
