Detailed Description

The present invention will be further described with reference to fig. 1 to 2.

A spray set for cold-rolled strip steel comprises a supporting seat, an annular spray thrower 4, a centrifugal pump 3 and a controller, wherein the controller is electrically connected with the centrifugal pump 3 and a walking device respectively. Two rows of support rods 8 which are parallel to each other are arranged on the support seat, and each row of support rods 8 comprises two support rods 8. In order to realize the omnidirectional cooling of the steel pipe, a walking device is arranged on the supporting rod 8, wherein the walking device is a double-track synchronous sliding table double-Y-axis electric sliding table linear module, and the two sliding tables are respectively connected with the bottom surface of the convex bracket base 2. The annular sprayer 4 comprises an annular cavity 402 and a plurality of spray nozzles 401, the inner ring of the annular cavity 402 is provided with spray ports with the same number as the spray nozzles 401, the spray nozzles 401 are connected with the spray ports, and the annular cavity 402 of the annular sprayer 4 is fixedly arranged on the support base 2 through bolts. The traveling device can drive the annular sprayer 4 to move in the horizontal direction, so that the full-length cooling of the strip steel is realized, and the strip steel is cooled by 360 degrees in an annular spraying mode.

In order to recycle the cooling liquid, reduce the usage amount of the cooling liquid and realize the filtration of the cooling liquid, a filter tank 602 is arranged on the support seat, a detachable filter plate 1 is arranged at the top of the filter tank 602, the filter tank 602 is used for storing the cooling liquid filtered from the filter plate 1, a liquid outlet 603 is arranged at the bottom of the filter tank 602, the liquid outlet 603 is connected with a liquid inlet of a centrifugal pump 3, and the liquid outlet of the centrifugal pump 3 is connected with a liquid inlet of an annular sprayer 4 through a pipeline 7; the controller is respectively electrically connected with the centrifugal pump 3 and the walking device.
