Laminar cooling water downward spraying edge shielding device

The utility model provides a laminar cooling water downward spraying edge shielding device, belonging to the auxiliary facilities in the production process of the metallurgy industry. The device is mainly used for a laminar cooling water control device of a roll steel production line and comprises a gear and two racks. The device is characterized in that the gear is arranged between the two racks; and a baffle is welded at one end of each rack. The device has the following beneficial effects: the device is installed on the upper part of a downward spraying collecting pipe; the width can be adjusted through relative motion of the gear and the racks; and the laminar cooling water downward spraying edge of the roll steel production line is shielded by a spray pipe, thus ensuring the edges of the strips not to be cooled.
