摘　　要：在常化炉后NAC快速冷却系统中,通过对高密度管流U形集管流量特性的分析,调整上集管数目,降低上集管发生断流时的流量值,选择合适的上下集管水量和水量比,实现对高温钢板的快速冷却或淬火工艺,得到平直的板形。In the controlled cooling system of NAC after normal furnace,the flux characteristics of the high density U pipe are analyzed,the numbers of upside header are adjusted,which are help to reduce the flux values of liquid breakup and the reasonable flux and the flux ratio of upside and downside pipe are chosen,all that is done is to realize controlled cooling and quenching of the high temperature plate,get the flat plate.

关 键 词：高密度管流 断流 控冷 淬火
