Technical Field

[0001] This invention relates to a hot-rolled adjustable roll spraying device. Background Technology

[0002] Rolls are the core functional components of rolling mills, directly determining rolling quality, equipment capacity, and production stability. As critical consumable parts, the service life and roll consumption per ton of steel have a significant impact on production costs. Hot rolling of steel can reach temperatures exceeding 1000℃. Effective cooling water spraying to reduce surface temperature can slow roll wear, stabilize roll gap, ensure rolling accuracy, and improve product quality and production efficiency.

[0003] During the production process, the position of the roll spraying device needs to be adjusted up and down and left and right as the position of the roll and the slot is adjusted. Conventional spraying devices and installation methods cannot meet the requirement of being adjustable in both the up and down and left and right directions. Therefore, it is necessary to manufacture many spraying devices of different sizes and specifications to cope with different roll sizes and positions. On the one hand, this leads to an increase in production costs, and on the other hand, replacing the spraying device also reduces the production efficiency of the rolling line.
