[0002] Steel heat treatment refers to a metal heat processing process in which steel is heated, kept warm and cooled in solid state to obtain the expected structure and performance. The heat treatment process includes three processes: heating, keeping warm and cooling. These processes are interconnected and cannot be interrupted. Cooling is also an indispensable step in the heat treatment process. The cooling method varies depending on the process, mainly to control the cooling rate.

[0003] According to a rapid cooling device for steel heat treatment processing with application number 202420041663.7, this solution effectively solves the problem that due to the high temperature of steel, the water will quickly heat up after contact with the steel, and there is a lack of cooling measures for the high-temperature water after entering the water storage tank, resulting in the continuous use of high-temperature water to spray the steel, affecting the cooling efficiency of the steel.

[0004] In the process of implementing this technical solution, the inventors found that there are at least the following problems in the prior art: the above solution uses a water pump to draw water from the water tank through the outlet pipe and discharge it into the cooling pipe inside the central box. The refrigerator draws in outside air to cool the air. The cold air enters the central box to cool the cooling pipe, so that the high-temperature water is quickly cooled. However, in the actual operation process, due to the differences in size and shape of the steel that needs to be heat treated, the fixed height spray position will not be able to completely cover the steel when cooling steel of different thicknesses, resulting in uneven temperature of the steel.
