Strip steel, also known as steel strip, is within 1300mm in width and its length varies slightly according to the size of each roll. In the production process of strip steel, quenching equipment for metal strip steel production is required.

[0003] However, since there is only one cooling barrel available, the cold water in the cooling barrel will quickly heat up after one quenching cooling. During the next quenching cooling, the water in the cooling barrel is not completely replaced, which results in the water in the barrel being unable to quickly cool the strip, thereby reducing the performance of the strip. Now, a strip production quenching device is urgently needed to solve the above problems. Utility Model Content

[0009] Furthermore, an ice adding port is provided at the upper end of the crushed ice temporary storage box.

[0010] Furthermore, a movable blocking door is installed at the right end of the crushed ice temporary storage box through a hinge.
