摘　　要：一种新型的棒线材在线控制冷却用的强力穿水冷却装置 ,采用无净化处理的轧机循环冷却水作为冷却介质。介绍了强力水冷装置的组成 ,防堵塞的原因是由于冷却剂在圆弧形沟槽内流动。A new water-cooling device for bar and wire production is introduced. The cooling water used is recycled water from rolling mill without treatment. The components, and the reason why the nozzles can not be clogged are described. The flow resistance of cooling water and the mechanism of eliminating steam jacket by suspension iron oxide particles are introduced.
