TECHNICAL FIELD

[0001] The present application relates to the field of strip steel processing technology, in particular to a strip steel water cooling device. BACKGROUND

[0002] The strip steel is a kind of narrow and long steel plate produced by various rolling enterprises to meet the needs of various industrialized production of metal or mechanical products in different industrial departments. In the production process of strip steel, the strip steel often needs to be cooled and cooled after processes such as conditioning and heat treatment.

[0003] In the related art, in order to cool the strip steel, a water cooling tank with water cooling nozzles is often used for water cooling of the strip steel. The water cooling tank is provided with an inlet and an outlet. During the treatment process, the strip steel is conveyed through the inner cavity of the water cooling tank by a conveying device, and then the water cooling nozzles in the water cooling tank continuously spray water on the strip steel for cooling under the water flow supplied by a water supply assembly.

[0004] For the above-mentioned related art, because the surface of the strip steel after water cooling often has attached water, the strip steel with water not only affects the performance of the strip steel itself, but also affects the processing effect of the subsequent processing equipment on the strip steel, and affects the detection accuracy of the performance of the strip steel by the subsequent detection equipment, so it needs to be improved.
