摘　　要：邯钢型棒材厂穿水冷却设备的优势表现在以无净化浊环水作为冷却介质。利用喷嘴喷出的含有大密度固体颗粒的动能打击棒材表面的蒸汽套，破坏了这层阻隔冷却介质与轧件之间热交换绝热层的连续性；冷却介质中的固体颗粒剖的组成蒸汽套的气泡的生命周期显著缩短，同时也增大冷却介质的汽化率，通过汽化潜热加大了棒材的冷却强度。Equipment＇ s obvious predominance of turbid water cooling equipment is shown applying to rebar in bar mill at Handan Iron and Steel Group Co. It is included that floating heavy particles release its kinetic energy when it impact vapour blanket on the hot rod surface. Due to coolant medium intercalate impurity grain, successive steam layer is destroyed. Steam jacket is consist vapour bubble, its natural life is shorten observably. As a result of steam layer nipout, coolant boil away rate is increase remarkably and hot rod is drop in temperature apace.
