摘要 为提高热轧带钢层流冷却卷取目标温度的控制精度,根据冷却过程的传热机理,分析了带钢层流冷却的传热过程。在此基础上,给出了冷却控制的空冷和水冷预测数学模型,分析并阐述了层流冷却控制系统的前馈控制算法及其在实际控制中的应用。本前馈控制的使用效果良好,具有较高的目标卷取温度控制精度,能满足生产的需要。 In order to improve the control precision of strip coiling temperature in laminar cooling, the heat transfer in cooling process was analysed from a viewpoint of transfer mechanism, and a mathematical model of air-cooling and water-coollng was obtained. The feedforward control algorithm and its application to laminar cooling system are described. The practice showe that the feedforward control has higher control precision of coiling temperature.
