介绍预计算轧制规程中所使用的轧制力模型，在此基础上根据轧制过程中的仪表反馈数据开发出一种新的轧制力自学习模型。并对轧制力自学习系数层别划分的方法，依据和效果做了系统的分析。现场在线应用结果表明:给出的轧制力模型具有良好的预测精度,末道次轧制力预测误差可以控制在3%以内，其他道次可以控制在5%以内。
Introduce the rolling force mathematic model used in pre-calculated rolling schedule and a new rolling force learning model based on feedback data from the instrument in rolling process. It is very necessary to analyze the method for division of learning coefficient layers, the gist and the effectiveness. The result of on-line application indicated that rolling force model has good precision of prediction with an error less than 3% in last pass and 5% in other passes.
