摘　　要：介绍了在冷轧薄板轧制过程中所使用的温度控制技术。传统的温度控制是控制轧辊温度以实现对板形质量的控制,此轧辊温度模型是计算轧辊与冷却液间的热量交换。从使用情况看,传统的模型对板形质量的控制有一定的波动,板形质量不能达到理想的目标。将传统的轧辊温度技术拓展到带钢温度控制技术上,能有效地提高板形质量。带钢温度模型用于计算轧制带钢时带钢温度增量(由轧辊的变形引起的带钢温度增量)和轧制后的带钢冷却温度。生产结果表明,使用拓展的带钢温度模型控制轧制的冷轧薄板极大地提高了板形质量。The temperature-controlling technology in cold strip rolling process is introduced. The traditional temperature-controlling technology affects the shape quality by controlling temperature of roils, and the roll temperature model is used to calculate heat exchange between rolls and coolant. In real use of the traditional model, the shape control fluctuates to some extent and the desirable shape quality can hardly be achieved. Now the traditional roll temperature model has been applied to the strip temperature -controlling technology, and the shape quality has been effectively improved. The strip temperature model calculates the temperature increment caused by roll deformation and the strip＇ s cooling temperature after it is being rolled. The production result indicates that the shape quality of cold strip has been greatly improved with the help of the developed strip temperature model.
