For the model of laminar cooling control of hot rolled strip,the accuracy of coiling temperature control is unsatisfactory because the heat transfer in the strip itself is ignored. 在热轧带钢层流冷却控制数学模型中，由于忽略带钢内部的热传导而使卷取温度控制精度不良。
The on-line and continuous flatness detection of the hot-rolled strip is one of the most important links in the modern strip shape control system on the hot strip mills. 热轧带钢平坦度的在线连续检测是现代热轧带钢连轧机板形控制系统中重要的环节之一。
