日本神户钢铁公司神户厂的小型轧机采用穿水式管状冷却装置对轧材进行在线控制冷却。在管状冷却器的两端有环形进水缝隙,下面有排水孔,上面有排气孔,可防止水在管内加热或产生蒸气时降低冷却能力。这套连续小型轧机共有16个机架。机架刚度高,可以进行较低温度轧制。粗轧机组有8 Japan’s Kobe Steel’s Kobe mill’s small mill uses a water-cooled tubular cooling device to control the rolling material online. In the tubular cooler at both ends of the ring into the water gap, there are drainage holes below, there are vents, to prevent water heating tube or steam to reduce the cooling capacity. This small continuous mill has a total of 16 racks. Rigidity is high and can be rolled at lower temperatures. Roughing mill has 8
