[0002] In the production of thick steel strips and high-speed production, the plate surface cannot be cooled down, resulting in a high temperature after the finished product is coiled. After packaging, the high temperature of the plate evaporates to form water vapor, which cannot be dissipated in the package. The water vapor is in contact with the plate surface for a long time, causing oxidation of the finished plate surface.

[0003] With reference to CN208817785U, a plate spray cooling device is developed, which belongs to the spray cooling device in the field of plate processing equipment, and includes a steel belt channel, a circulation motor, a circulation pipe and a protective cover. The circulation motor is connected to the flower-shaped nozzles in the protective cover through the circulation pipe. The flower-shaped nozzles are located on both sides of the inside of the protective cover, and the steel belt channel is located between the flower-shaped nozzles on both sides of the inside of the protective cover; a reflux hole is provided under the protective cover, and the reflux hole extends into the reflux pool under the protective cover; the reflux pool is connected to the water storage tank through the reflux pipe; the water storage tank is connected to the cooling equipment through a pipeline and is connected to the circulation motor; the circulation motor sprays the cooled water on both sides of the plate surface through the flower-shaped nozzles, which directly and effectively reduces the temperature of the plate surface, and the plate surface cannot volatilize water vapor, thereby preventing the contact between water vapor and the plate surface, effectively controlling the oxidation of the plate surface, and ensuring the quality of the product; the flower-shaped heads on both sides directly spray the cooled water on both sides of the plate surface, and the structure is simple and easy to maintain.

[0004] However, the following problem still exists: the device only uses water mist spraying to cool down, which results in slow cooling speed and prolonged cooling time, affecting the cooling speed. Utility Model Content
