摘　　要：针对极薄板小变形平整机稳态轧制负荷计算困难的问题,基于平板压缩复合变形假设,提出了改进的平整稳态轧制力及轧制力矩的数学模型.轧制力模型包括辊缝区等效变形区长度和压缩变形抗力2个经验模型;在轧制力模型计算的基础上,用输出力矩模型对带钢张力影响因素进行了经验修正;通过轧制负荷模型的理论计算结果和一条生产线的实际参数比较,证明模型具有较高计算精度,平板压缩变形假设合理.将所开发的模型应用于一条新建的极薄板平整生产线的关键设备参数的设计评估,结果表明该模型具有较高的工程应用价值.Aiming to solve the difficulties in calculating the stable roll load of temper-mill which is especially used to dryly temper thin-gauge strip with the small reduction, an improved roll model and torque model were proposed on the basis of hypothesis of flat plate compression. The roll model includes two experiential sub-models, equivalent deformation length and deformation assistance and the torque model is linearly corrected especially considering the tension effects. The comparison between the actual and calcu- lated results shows that the models possess high precision and the hypothesis is reasonable. Finally, the key parameters relative to the roll load of a new establishing double stands temper mill were checked via the new developed models, which displays the models have the value of applications in real projects.
