プはメッキ浴から出て、クーリングタワーまで垂直に上
昇し冷却装置を通過して冷却される。For example, in the plating section of a hot-dip galvanizing plant, the strip leaves the plating bath, ascends vertically to a cooling tower, and is cooled by passing through a cooling device.
この垂直部はストリップが亜鉛ポットから出て冷却し得
るだけの高さが必要であり、ライン速度が速くなれば当
然その高さは増大することとなる。This vertical section needs to be tall enough to allow the strip to exit the zinc pot and cool, and of course increases in height as the line speed increases.

３５０°Ｃ以下の冷却が必要とされており、通常垂直部
においてこれを自然冷却或いはエアージェットにより行
なっている。Normally, the deflector roll at the top of the cooling tower requires cooling to below 350°C due to the problem of plated zinc adhering to the roll surface (product defects due to peeling of the plating and roll build-up). This is done by natural cooling or air jets.

望まれていた。In the case of this type of conventional cooling, the cooling capacity is naturally limited, and with the recent high-speed galvanizing equipment, the height of some parts of the cooling tower is over 40 m, and of course the building must be designed to accommodate this. It becomes necessary to increase the height of the building, and space is required.
It was desired to use other means for efficient cooling, both in terms of construction costs.
本発明はかかる問題を解決する手段を講じたもので、メ
