DETAILED DESCRIPTION
[0018] As shown in the accompanying drawings, this embodiment provides a water sealing device for hot-rolled titanium working rolls, including an anti-entanglement guide plate 8, which is a main component of the rolling equipment body and is used to prevent the steel from curling during strip rolling. The matching rolling equipment is a hot-rolled reversible rolling mill, the rolling mill body of which is stacked by two support rolls 9 and two working rolls 10, the roll system is equipped with a water cooling system 11, the front and rear of the rolling mill body are connected to a transport roller 12, and the anti-entanglement guide plate 8 is located on both sides of each working roll 10.
[0019] The components that play the role of sealing water in this embodiment include a felt locker 1, which is a long U-shaped structure. A plurality of screw holes 2 are arranged on the opposite side of the open end of the felt locker 1, and each screw hole 2 is connected to a corresponding screw rod 3. An installation groove corresponding to the felt locker 1 and installation holes corresponding to each screw rod 3 are opened on the anti-entanglement guide plate 8. The felt locker 1 is installed in the installation groove, and each screw rod 3 passes through the corresponding installation hole and is locked by a locking nut 4 respectively.
[0020] A spring 6 is provided on each screw rod 3 between the anti-entanglement guide plate 8 and the locking nut 4. The spring 6 is provided to adjust the water sealing effect at different positions within the length range of the roller so that each position can achieve the best water sealing state.
[0021] A rectangular felt 13 is inserted and fixed in the felt locker 1 , and pin holes 7 are provided on both sides of the opening of the felt locker 1 . The rectangular felt 13 is fixed in the felt locker 1 by driving pins into the pin holes 7 .
[0022] The rectangular felt 13 is made of high-strength fiber felt, which is wear-resistant and high-hardness. The rectangular felt 13 is made to fit the surface of the roll due to its softness and water absorption, so that the cooling water can be diverted. The length of the rectangular felt 13 is consistent with the roll surface length of the working roll 10. The main purpose is to spread the cooling water on the roll surface to both sides to prevent cooling water from remaining on the roll.
