Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a water circulation cooling device for steel production. Background Technique

[0002] A steel strip, also known as a strip steel, is a steel product with a width within 1300 mm. It is generally supplied in coils, so it is also called a steel strip coil. It has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. The production of steel strip coils generally includes process flows such as batching, melting, casting, rolling, annealing, post-treatment, and coiling; after the existing steel strip is melted, it is cooled by a water circulation cooling device to make the steel strip quickly take shape. The temperature of the cooling water rises after contacting the steel strip and needs to be cooled before it can be recycled.

[0003] Chinese Patent with the authorization publication number of CN219079603U discloses a water circulation cooling device for steel production, which relates to the technical field of water circulation cooling devices, including a box body, a conveying roller, and a water tank. A conveying roller is arranged inside the box body, and a water tank is arranged below the inside of the box body. A partition is arranged inside the water tank. The water tank is divided into an upper water tank and a lower water tank by the partition. A water inlet pipe penetrates through the right side of the upper water tank and extends out of the inside of the box body, and a drain pipe penetrates through the right side of the lower water tank and extends out of the inside of the box body. A spraying mechanism is arranged on the right side of the box body, and a temperature reduction mechanism is arranged on the left side of the box body; in the utility model, a temperature reduction mechanism is arranged on one side of the box body, and the compressor in the temperature reduction mechanism injects the refrigerant in the refrigerant tank into the temperature reduction chamber to cool the water. The speed of using the refrigerant to cool the water is relatively fast, which is convenient to avoid the problem that the traditional water circulation device has a slow cooling speed when using a fan.

[0004] However, when this technology is used, when cooling the steel strip, iron oxide chips on the steel strip will fall off, and the generated oil stains and various impurities will pollute the cooling water. This technology cannot filter the impurities in the cooling water, resulting in blockage inside the water pipe, thereby affecting the cooling effect and cooling efficiency of the water circulation. Therefore, it is necessary to further improve the water circulation cooling device for steel production. Content of the Utility Model
