摘　　要：中厚板轧后超快速冷却系统通常采用流量-开口度曲线来加快集管流量调节速度,同时曲线标定精度直接影响集管流量调节精度.以应用于多家中厚板厂的一种新型超快速冷却设备为例,分析其电动调节阀的调节特性,给出流量-开口度曲线自动标定的有效方法.结果表明,利用该自动标定方法对集管进行流量-开口度曲线标定,在增加标定曲线维护便捷性的同时,改善了流量-开口度曲线的控制速度和精度,为提高流量控制速度和精度提供强有力的技术手段.Flow-opening degree calibrating curve is usually used for accelerating the control speed of flow in the ultra fast cooling system of plate mill. The precision of calibrating curve influences directly the accuracy of flow control. Taking the new ultra fast cooling equipment applied in many plate mill plants of iron and steel group corp as an example, the electric valve regulating characteristics was analyzed, and the effective auto-calibrating method of flow-opening degree calibrating curve was developed. The results showed that this method of obtaining flow-opening degree calibrating curve by using flow auto-calibrating technology not only is convenient for maintenance but also achives the better speed and accuracy of flow control. It could be used to improve the design of ultra fast cooling equipment and control system.
