角钢连轧前滑模型的在线识别

On-Line Identification of Foward Slip Model for Continuous Rolling Steel Angles

摘要: 在正常连轧生产条件下,同时在线采集轧辊与轧件速度并采用电源-力矩法估计机架间张力值,可以在线识别前滑模型。通过引入自适应校正方法,可以进一步提高辊速的设定精度。

Abstract: By simultaneously sampling the roll-bar speed and estimating the tension by electric current-torque method, the forward slip model for continuous shape rolling can be identified on-line. More exact roll speed can be predicted by introducing the adaptive control in mill set-up system.
