超快冷技术在2150 mm热连轧机层流冷却控制系统的应用

Application of Ultra Fast Cooling Technology in Laminar Cooling Control System of 2150 mm Hot Tandem Mill

针对原有层冷控制系统在生产厚规格产品时,时常出现温度控制异常的现象,引进了超快冷技术。以2 150 mm热轧生产线为例,利用前置快速冷却方式对其进行升级改造,提升了冷却温度控制精度,取得明显的控制效果。

In view of the abnormal temperature control of the original layer cooling control system in the production of thick products, ultrafast cooling technology is introduced. Taking the 2 150 mm hot rolling production line as an example, the pre rapid cooling mode is used to upgrade it, which improves the cooling temperature control accuracy and achieves obvious control effect.
