摘　　要：采用差分法建立了轧辊二维温度场及热辊形的仿真模型 ,并利用实际生产参数进行仿真 ,仿真结果与实测值相符。本温度场及热辊形模型可用于实际生产的在线热凸度预报。Using the finite-difference method,it is developed a two-dimension axisymmetric model to compute the work rolls′ transient temperature field and thermal profile. By calculating with rolling data from the spot, study work roll thermal profile in the whole process of rolling and cooling. Measured data on spot are utilized to test the model to ensure the model′s validity.The model can be used to predict work roll thermal profile on-line.
