层流冷却模型主要是依据热轧带钢钢种、规模、温度、速度等工艺参数的变化,通过预设定、前馈控制、反馈控制,并对自适应模型更新,从而控制冷却集管的开闭,调节冷却水流量,实现带钢卷取目标温度的精确控制。通过对层流冷却模型的再开发和调试,实现了卷取温度高精度实时预报、控制,取得了良好的控制效果。 Laminar flow cooling model is mainly based on the hot strip steel, size, temperature, speed and other process parameters change, through the pre-set, feedforward control, feedback control, and adaptive model updates to control the cooling manifold Open and close, adjust the flow of cooling water, to achieve precise control of the target temperature strip coiling. Through the re-development and debugging of the laminar cooling model, real-time prediction and control of the coiling temperature with high precision are realized, and a good control effect is achieved.
