Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cooling, in particular to a controlled cooling device for hot-rolled medium and thick plates. Background Art

[0002] A type of plate commonly used in engineering with a thickness much smaller than the plane size, a steel plate with a thickness of 4.5mm to 25mm, is called a medium and thick plate. After the medium and thick plate is heated to the required temperature and maintained for a certain period of time, it is cooled with a selected cooling rate and cooling method to obtain the required structure and properties. This process is called the medium and thick plate heat treatment process.

[0003] The existing Chinese utility model patent with reference announcement number: CN113714313A discloses a controlled cooling device for hot-rolled medium and thick plates. The present invention provides a cooling mechanism, which can perform real-time water spraying operations on multiple surface areas of the medium and thick plates through a "mouth"-shaped water spray box during the cooling of the medium and thick plates, thereby ensuring rapid cooling of the medium and thick plates while achieving a uniform cooling temperature. At the same time, it also avoids the problem of the prior art that multiple water supply systems occupy too many resources during cooling due to synchronous operation.

[0004] The above-mentioned device can only cool the top surface of the medium and thick plate during cooling. However, when cooling the bottom surface, it needs to be turned over and transported for cooling again. The cooling efficiency is low, which reduces the processing progress. Moreover, the water after spraying falls into the water tank, and the water inside the water tank cannot be cleaned, which affects the next use. Therefore, the technical personnel in this field provide a controlled cooling device for hot-rolled medium and thick plates to solve the problems raised in the above-mentioned background technology.
