[0002] With the rapid development of the steel rolling industry, the market competition for plates and strips is becoming increasingly fierce. The realization of mass production of high-end products has become the primary goal of the industry's development. At the same time, due to the rapid development of the aviation, automobile, and home appliance industries in recent years, users have higher and higher requirements for high-surface quality and high-value-added plate and strip products. The demand is increasing day by day, and with the continuous development of the trend of replacing cold-rolled steel plates with hot-rolled steel plates in the rolling field, the requirements and indicators for the surface quality of hot-rolled plates and strips are also constantly improving. In the process of processing hot-rolled stainless steel plates and strips, a cooling device is used for rapid cooling. In the cooling process, the traditional cooling device will quickly heat the cooling water when the cooling water contacts the high-temperature stainless steel. The cooling water boils and evaporates to produce a large amount of hot steam. The lack of structure to collect the hot steam will scald the surrounding staff or corrode the surrounding electrical equipment; the cooling water temperature is not low enough, which affects its cooling effect on high-temperature stainless steel.

[0003] A hot-rolled strip cooling device disclosed in publication number CN202527486U, although the utility model provides an asymmetric cooling device for hot-rolled strip, which can eliminate the temperature difference between the upper and lower surfaces of the strip, alleviate the warping of the finished strip, and improve the uniformity of the metal structure of the vertical section of the strip.

[0004] However, this hot-rolled strip cooling device has the following disadvantages:

[0005] (1) In the cooling process of traditional cooling devices, the cooling water contacts the high-temperature stainless steel, which will heat the cooling water quickly. The cooling water boils and evaporates to produce a large amount of hot steam. There is no structure to collect the hot steam, which will burn the surrounding staff or corrode the surrounding electrical equipment.

[0006] (2) The cooling water temperature is not low enough, which affects its cooling effect on high-temperature stainless steel. Utility Model Content

It solves the problems raised in the above-mentioned background technology that there is a lack of structure to collect hot steam, which may scald surrounding personnel or corrode surrounding electrical equipment, and the cooling water temperature is not low enough.

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a stainless steel hot-rolled strip cooling device, comprising a cooling trough, a cavity is opened inside the cooling trough, a high-pressure nozzle is connected to the inside of the cavity, a cooling component is connected to the bottom surface of the cavity, a plurality of moisture-proof sleeves are overlapped on the top surface of the cooling trough from left to right, an air outlet is opened on the top surface of the moisture-proof sleeve, an impeller structure is connected to the top surface of the air outlet, and a moisture-proof component is connected to the top surface of the impeller structure.
