Abstract

ABSTRACT In view of the influence of the fluctuation of incoming material composition, finishing temperature and coiling temperature on the deformation resistance in the cold rolling process during the hot rolling process, the optimization objective function is established by combining the analytic method and big data regression. Further, the relevant characteristic coefficients are calculated through a large number of on-site actual data, and the deformation resistance model of hot-rolled finished strip and the rolling pressure prediction model of cold rolling process are obtained. Through the field test, the deviation between the predicted rolling force and the actual rolling force is less than 2%, and the accuracy of the model can meet the engineering requirements. More importantly, after using the research results described in this paper, the quality of cold rolled strip shape has been significantly improved, which can greatly improve the economic efficiency and market competitiveness of enterprises.

基于热轧参数的带钢冷轧变形抗力及轧制力预测研究

摘要针对热轧过程中来料成分、精加工温度和卷取温度波动对冷轧过程变形抗力的影响，采用解析法和大数据回归相结合的方法建立优化目标函数。进一步，通过大量现场实际数据计算相关特征系数，得到热轧成品带变形抗力模型和冷轧过程轧制压力预测模型。通过现场试验，预测轧制力与实际轧制力偏差小于2%，模型精度满足工程要求。更重要的是，运用本文所述的研究成果后，冷轧带材的板形质量有了明显的提高，可以大大提高企业的经济效益和市场竞争力。
