| 摘 要： | 带钢冷却是一个多阶段的过程，各阶段间存在相互影响。热轧带钢在水冷却区冷却单元下的冷却是一种机理很复杂的非对称性冷却，难以用精确的数学模型进行描述。为此提出了对称性冷却假设条件下的建模方法，得到结构相对简单并适合过程控制的数学模型，并给出了在线控制的前馈算法，最后推导出可用集总参数法的最大带钢厚度值，简化了带钢厚度方向温度分布的在线控制。

| Abstract: | The cooling process of strip is a multi-stage process, and there is interaction jet impingement stages. The cooling process of elements on strip is non-symmetric, the cooling mechanism is sophisticated. It is difficult to describe the process by mathematic model. Based on a reasonable symmetric cooling assumption, it is possible to obtain relatively simple mathematic model which is applicable to the on-line control. The modeling method under the symmetric cooling assumption and the algorithm of on-line feedforward are given. In order to improve the efficiency of control system further, the maximum thickness which can be used in lump system is deduced by using of Biot number in the last part. |
