[0015] Beneficial effects of the utility model:

[0016] The utility model fixes the main pipe of the spray device in the continuous casting secondary cooling chamber. When replacing the section, only the spray ring needs to be replaced. The replacement operation is simple and convenient, which can reduce the workload and labor intensity of workers replacing the spray device and shorten the replacement time.

[0017] By designing a quick-connect connector on the main pipe, workers only need to unplug the old spray ring from the main pipe, then insert the new spray ring and fix it with an oblique iron pin. The operation is simple and convenient.

[0018] Through the design of the connecting mechanism, when replacing the section of the continuous casting machine, the worker first removes the inclined iron pin, then removes the pressure block, pulls out the spray ring from the water outlet, and then installs a new spray ring into the water outlet. The spray ring is pressed with the pressure block again, and the inclined iron pin is inserted at the same time. The spray ring is stably connected to the quick-connect connector through the inclined iron pin and the pressure block.

[0019] The design of the quick-connect connector facilitates the connection of the water channel, and the quick-connect connector can be automatically sealed when directly inserted into the water inlet to prevent leakage of the secondary cold water. BRIEF DESCRIPTION OF THE DRAWINGS
