摘要： “1+4”铝热连轧机是一个极其复杂的系统，为了精确地建模预报末机架出口处的板凸度，提出利用延时反馈BP网络对板凸度时间序列的预报方法来实现对铝带板凸度的精确建模预测。通过现场实验，采集大量试验数据，并通过数据分析，利用仿真验证该方法的有效性和优越性。

Abstract: “ 1+4 ” aluminum hot tandem rolling mill is a complicated system extremely. In order to predict crown of aluminum strip of the finisher delivery more accurately, this paper puts forward a method of timelapse loop BP network to forecast the sequencing crown， and the reconfiguration of BP network is trained with LM algorithm. With a large number of test data gathered by onthespot experiment and analysis, simulation experiment indicates the predictive precision of relative crown(%) of strip can reach 0.01%, effectivenes and superiority is proved.

Key words: aluminum strip hot tandem rolling mill, crown of strip, timelapse feedback BP network, LM algorithm, prediction of sequence
