中厚板轧后超快速冷却水流量的控制速度直接影响轧机的轧制节奏，水流量的控制精度直接影响钢板冷却过程的控制精度。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，给出提高流量调节速度和流量调节精度的有效方法，为超快速冷却设备和控制系统的优化设计提供参考依据。
The flux control speed of ultra fast cooling system in medium and heavy plate can affect the rolling rhythm of the mill, and the flux control accuracy can affect the control accuracy of the plate cooling process. Taking the new ultra fast cooling equipment applied to many medium and heavy plate plant of iron and steel group co as example, the electric valve regulating characteristics was analyzed, the effective method to improve the control speed and accuracy was given, and the reference for the ultra fast cooling equipment and control system design was provided.
