The positioning plate 1 is a metal plate and is arranged at the bottom of a cross beam of the rolling mill housing, and the end parts of the two sides of the positioning plate are welded with the upright post of the rolling mill housing. The slide rail 2 is arranged at the bottom of the positioning plate 1, and the pipe clamp 3 is in sliding connection with the slide rail 2. The water pipe 4 penetrates through the pipe clamp 3, and a water inlet of the water pipe 4 is connected with a water outlet of the flushing water tank 6. Nozzle 5 is located directly over the mangle, nozzle 5 includes arc body 51, inlet opening 52 and apopore 53, the inside of arc body 51 is the cavity, inlet opening 52 locates arc body 51's top, with the delivery port welding of water pipe 4, apopore 53 evenly distributed is in arc body 51's inboard.

When the flushing device of the embodiment is used, the water pressure of the water pipe 4 is adjusted according to the linear velocity of the roller, the pipe clamp 3 drives the water pipe 4 to move along the slide rail 2, and high-speed water flow in the nozzle 5 is sprayed from the water outlet holes 53 to impact the rolling groove, so that the rolling groove is cooled rapidly.
