摘　　要：以热轧实测数据为基础,对不同钢种进行计算并选取基准变形抗力。以周纪华·管克智模型作为目标变形抗力数学模型,采用多元非线性回归的方法完成对碳素钢、合金钢共7个钢种变形抗力模型的优化,并选用特列齐亚科夫·久津模型和井上腾郎模型作为对比进行回归,确定以实测数据为基础的变形抗力模型,且采用对应模型预测除样本数据外钢卷轧制力,证明采用多元非线性回归的方法自学习系数效果较好。Based on the hot rolling measured data, the benchmark of the deformation resistance for different steel grades was cal-culated and selected. Taking Zhou Jihua 8〈 Guan Kezhi model as the objective deformation resistance model, using multivariatenonlinear regression method, the deformation resistance models of total seven types of steel including carbon steel and alloy steelare optimized. Meanwhile, taking Te Leo Zia Kopf zyuzin model and Inoue Ro model as contrast models for comparison, the de-formation resistance models are determined based on the measured data of hot rolling. Except for the sample data, the steel coilrolling force can be well predicted with corresponding models.
