rolling error

It has proved in practice that in large initial thickness error condition the lot rolling qualified rate increase 5%~ 10% and the influence to flatness after AGC putting in work is reduced.

试验表明，在大初始偏差下，该算法比传统AGC控制算法的批量轧制合格率提高5%～10%，并减少了AGC投入后对板形的影响。

Rough rolling and pure rolling temperature drop model is derived by regression statistics way with the measured data, can see this model has good prediction, forecast and actual temperature temperature ± 15% than basic error.

粗轧和精轧的温降模型通过回归统计的方式导出，与现场的实测数据比较，可以看出该模型具有很好的预测度，预测温度与实际温度的误差基本不超过±15%。
