摘　　要：为了提高分段冷却在板形控制中的作用,对1400F铝带箔轧机工作辊与冷却液之间对流换热特性进行了模拟研究,采用正交实验方法获得了一组最优的冷却参数,并进行了模拟验证.结果表明,影响冷却效率重要性的因素依次是冷却液粘度、喷射速度、冷却液温度和喷射角度.The function of stage-cooling in flatness control becomes more important than ever before by many examples in factories. On the base of the convection heat transfer between the working rolls and the coolant fluid of the aluminum mill 1400F, the optimum values of convection heat transfer were found through orthogonal experiments and proved to be optimal by numerical simulation. The factors in orthogonal experiments arranges as the viscosity, the speed, the temperature and the spraying angle of coolant fluid in the order of importance.
