摘　　要：通过对轧件在粗轧区内的传热分析,考虑辐射散热、除鳞水、工作辊与轧件热传导以及轧制过程中变形热,建立了在线温度模型,并采用有限差分法进行求解。将该温度模型应用于某厂1 750 mm热连轧机,应用结果表明,温度模型计算值与实测值吻合良好。Based on analysis of heat transfer of rolled piece in rough rolling zone, considering radiation, descaling, heat conduction between work roll and rolled piece, and deformation in rolling process, an on-line temperature model was established, and solved by use of finite difference method. The model has been applied to 1 750 mm hot rolling mill in a certain factory. Application results show that the value calculated by the model is identical with measured value.
