摘　　要：针对薄带钢平整轧制时厚度薄、压下率小的特点,结合参数修正与非线性回归分析,建立了平整机负载辊缝模型,计算结果表明,该模型符合实际轧制情况,计算精度高,相对误差小,能够准确预报板形。Combinating parameter modification and nonlinear regression analysis,the model of loading roll gap was established according to the characteristics of strip with thin gauge and low percent reduction during tempering. The results showed that the model could meet the practical rolling situation which had high accuracy and little error,and could forcast the shape exactly.
