摘　　要：以国内某4300mm中厚板生产线轧后先进冷却系统为研究对象,对中厚板轧后冷却过程中冷却速度的影响因素及控制方法进行研究.分析了换热、喷嘴形式及集管水流密度等因素对冷却速度的影响,确定出不同厚度规格钢板的冷却速度控制范围.建立了冷却速度计算模型,并结合自学习方法实现对冷却速度的高精度控制.利用该控制系统对12MnNiVR进行轧后冷却过程控制,结果表明被控钢板具有较高的冷却速度控制精度.The influencing factors and the control method of plate cooling rate during a controlled cooling process after rolling were researched for the 4 300 mm plate mill with the advanced cooling system.The effect of heat transfer,nozzle and the flow rate of header on cooling rate was analyzed to confirm the control scope of the cooling rate for different thickness plates.The calculation model of cooling rate was established to improve the control accuracy of cooling rate by combining the self-learn method.The control results showed that the cooling rate of the steel 12MnNiVR was controlled with high accuracy.
