摘　　要：采用一种具有较高精度的样条有限条法对轧制过程中工作辊的温度场和热凸度进行计算和预报。结果证明,该模型理论计算值与现场实测值吻合较好,可以较准确地计算和预报热带钢连轧机工作辊的热凸度。The spline finite strip method, which has a high precision, was adopted to calculate and predict the work roll temperature field and crown. This prediction model was used in the presetting system of shape and crown for 1 450 mm hot strip mill. It is found that the model can predict the thermal crown of a hot strip mill with high accuracy.
