Device for removing oxide scale bonded at grooves of heavy-rail universal mill

The utility model discloses a device for removing oxide scale bonded at grooves of a heavy-rail universal mill effectively. The device comprises a first group of nozzles, a second group of nozzles and a third group of nozzles. The first group of nozzles are used for spraying lubricant to circular-arc transitional sections of the inner sides of groove legs and connected with a first lubricant delivery pipe; the second group of nozzles are used for spraying lubricant to two ends of groove heads and connected with a second lubricant delivery pipe; the third group of nozzles are used for spraying lubricant to middles of groove waists and connected with a third lubricant delivery pipe. Positions, easy to be bonded with oxide scale, of the grooves, are sprayed with lubricant purposefully, so that the positions are prevented from being bonded with oxide scale, and the oxide scale bonded recently can fall off rapidly.
