Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled coil processing, and specifically relates to an external cooling device for a reel of a hot-rolling coiler. Background Technique

[0002] During the production process of hot-rolled steel coils, after the hot-rolled coils are hot-rolled and cooled by laminar flow, the temperature is still as high as 640 - 850 °C. This requires air cooling in the hot coil storage before entering the next process for hot annealing and pickling. The purpose of post-rolling cooling is to prevent the high temperature of the hot-rolled steel coils from having an adverse impact on the subsequent acid rolling production line equipment.

[0003] There is a water-cooling device for hot-rolled coils as disclosed in Chinese Patent Publication No. CN216606673U. Through the cooperation of a curved rod, a sleeve, and a threaded rod, the water-cooling device can not only adjust the height of the nozzle but also adjust the angle of the nozzle to achieve rapid, uniform, and large-angle cooling of hot-rolled coils of different sizes. At the same time, since all the cooling work is carried out inside the box, it can effectively prevent water from instantaneously evaporating and splashing during the cooling process of the hot-rolled coils, which is likely to cause harm to the staff, and can also play a good role in saving water and avoiding waste of water resources.

[0004] However, in this water-cooling process, the subsequent water temperature is high, the circulation efficiency is low, and the practicability is poor. Content of the Utility Model
