针对中厚板轧制过程中钢板温度场不易精确模拟,传统温度计算模型存在较大计算误差的问题,提出了道次间的钢板温度修正模型。该模型利用上道次的实测数据,如测温仪温度、轧制力等,对钢板的温度场进行修正。并将修正后的钢板温度场应用到后续未轧道次的辊缝修正计算中。实际应用表明,该温度修正模型投入使用后,轧制力预报精度和成品厚度精度有了很大提高。

In view of the difficulty of accurately simulating the temperature field of steel plate in the process of plate rolling and the large calculation error of the traditional temperature calculation model, a steel temperature correction model between passes is proposed. The model uses the last measured data, such as thermometer temperature, rolling force, etc., to correct the temperature field of steel. The modified steel temperature field is applied to the correction of the roll gap in the subsequent un-rolled pass. The practical application shows that after the temperature correction model is put into use, the accuracy of the rolling force prediction and the precision of the finished product thickness have been greatly improved.
