| 摘 要： | 结合现场情况介绍了热轧带钢层流冷却设备和控制系统的数学模型,其中数学模型主要包括空冷模型、水冷模型、反馈控制模型和自学习模型.由于某热轧厂采用非匀速轧制工艺制度,带钢在冷却区内既有较大升速又有较大降速,原层流冷却系统不能够适应轧制速度的变化而影响卷取温度控制精度,故需针对轧制速度的变化进行速度前馈补偿控制;从过程自动化...

| Abstract: | Equipment and mathematical models of a hot strip mill laminar cooling control system were described.Mathematical models of the system consist of models for air cooling,laminar cooling,feedback control,and self-learning.The original laminar cooling system was unable to effectively handle the relatively large changes in strip speed in the cooling area,thereby significantly compromising coiling temperature control accuracy.Speed feedforward compensation was proposed to achieve more adequate coiling temperature... |
