摘　　要：基于交替差分的方法建立无头轧制温度场及热变形计算模型,用于实际生产中轧辊热辊形的预报,并结合某轧制计划,计算了轧制过程中工作辊的温度场与热辊形,计算结果与理论分析一致。模型计算结果还可以用于对轧辊冷却水的分析,即对水量、温度和沿辊身不同部位所需冷却水的准确需求进行预测,为轧辊冷却水集管的布置形式和控制方式的优化提供理论依据。Based on the method of alternating difference,the calculation model of temperature field and thermal deformation of headless rolling is established,which is used to predict the hot roll shape in actual production.Combined with a rolling plan,the temperature field and hot roll shape of the work roll in the rolling process are calculated,and the calculated results are in agreement with the theoretical analysis.The calculation results of the model can also be used for the analysis of roll cooling water,that is,the accurate demand of water quantity,temperature and cooling water required in different parts of the roll body can be predicted,and the theoretical basis can be provided for the optimization of roll cooling water manifold layout and control mode.
