针对基于弹跳方程的轧制力宽度控制(RF-AWC)不能满足实际生产需求的问题,结合RF-AWC的控制原理和实际应用情况,提出一种采用轧机弹跳特征曲线方程进行宽度计算的新型RF-AWC。利用新型RFAWC对带钢宽度偏差进行调节,可以有效避免轧机刚度系数对弹跳方程的影响,从根本上解决了RF-AWC宽度计算的问题。针对卷取机建张造成的带钢头部缩颈问题,提出自适应缩颈补偿(NEC)策略,提高带钢头部宽度控制精度。现场应用效果表明,本文提出的宽度控制策略取得了良好的控制效果。
Aiming at the problem that the rolling force width control (RF-AWC) based on the bounce equation can not meet the actual production requirements, a novel RF calculation method based on bounce characteristic curve of rolling mill is proposed based on the control principle and practical application of RF-AWC. -AWC. Using the new RFAWC to adjust the strip width deviation can effectively avoid the influence of rolling mill stiffness coefficient on the bounce equation and fundamentally solve the problem of RF-AWC width calculation. Aiming at the problem of constriction of the strip head caused by the winding machine Zhang Jian, an adaptive necking compensation (NEC) strategy is proposed to improve the control precision of strip head width. The field application shows that the width control strategy proposed in this paper has achieved a good control effect.
