Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a cooling device for a steel-outlet roller table. Background Art

[0002] The roller equipment of the steel mill is responsible for transporting high-temperature slabs. The temperature of the slabs out of the furnace can reach up to 1250°C. Therefore, the rollers in contact with them heat up very quickly and must be cooled to ensure the strength of the roller surface and the safe temperature of the bearing seat. The original steel-out rollers did not have surface cooling water. In actual production, the steel temperature was too high, which caused great wear on the rollers, seriously affecting the quality of the finished products. As a result, the rollers needed to be checked frequently. At the same time, due to the harsh working environment, it caused certain troubles for the workers.

[0003] For example, the existing publication number CN210647750U is a steel rolling roller cooling device. This patent injects cold water into the outer roller and installs a refrigeration pipe in the inner cavity for cooling. This method can fully cool the roller and avoid uneven cooling, greatly improving the cooling effect of the roller and extending the service life of the roller. At the same time, a water mist spraying device is provided at the bottom of the steel rolling roller, and the connecting pipe drives the rotating water mist nozzle 180° to spray water mist, which can basically ensure that the roller will not be damaged by the high-temperature rolled steel, greatly ensuring the working efficiency of the roller and extending its service life.

[0004] However, the water mist sprinkler at the bottom of the roller in the disclosed patent is not provided with a structure for recycling its water droplets after operation, which easily causes a waste of water resources. In addition, the water mist sprinkler at the bottom directly sprays the roller surface, which will cause the moisture on the roller surface to contact the slab surface. After the moisture contacts the high-temperature slab, not only the temperature will become very high, but also it will be mixed with some impurities or dirt. As the roller rotates, the impurities will adhere to its surface and then fall with gravity. Although it will not easily cause blockage to the nozzle in spraying, after the nozzle stops working, the residual impurities or dirt will cause blockage to the nozzle that is not spraying after falling, affecting the next use of the nozzle.

[0046] In this embodiment, the top of the water tank 13 is connected to a water injection pipe 22, and the bottom side of the water tank 13 is connected to a drain pipe 23. A control valve is provided on the drain pipe 23. Under long-term water cooling and water evaporation, new water can be injected into the water tank 13 through the water injection pipe 22, and when the water in the water tank 13 needs to be discharged, the control valve on the drain pipe 23 can be opened to drain the water in the water tank 13.

[0047] The working principle and use process of this utility model:

[0048] Before use, the cylinder 9 drives the rack 8 to move on the guide wheel 20, causing the rack 8 to drive the supporting empty pipe 5 to rotate via the gear rotating member 7, so that the supporting empty pipe 5 drives the nozzle 6 to change its angle, and the nozzle 6 can be tilted toward the bottom end of the roller 3, and its spray water source is in the opposite direction of the rotation of the roller 3, and then after the water pump 11 works, the main valve 104 is opened, so that the water source can enter the supporting empty pipe 5 through the branch pipe 103, and spray water mist outward through the nozzle 6, so that the water mist is sprayed onto the surface of the roller 3, so as to detect whether each nozzle 6 can work normally. For the damaged nozzle 6 that does not spray, the staff can Manually close the single valve 105 on the corresponding branch pipe 103, and then dismantle the positioning bolt 16 to allow the supporting empty pipe 5 to rotate as a single unit, thereby facilitating the staff to dismantle and replace the damaged nozzle 6. It is simple and convenient, and there is no need to close the main valve 104 for replacement. It also avoids the problem of water source spraying affecting the staff's replacement environment when the main valve 104 is not closed and the angle is adjusted and replaced through the adjustment component. When the nozzle 6 of the slab conveyed by the roller 3 is damaged, the staff can replace the damaged nozzle 6 by the above method during the conveying interval, so as to realize replacement without stopping production. It is simple and effective.

[0049] During use, when the slab is transported on the roller 3, the water pump 11 is started, so that the water in the water tank 13 passes through the refrigerator 12 and is then transported to the supporting empty pipe 5 through the water supply pipe body 10, so that multiple nozzles 6 can spray water mist onto the surface of the roller 3 to cool the surface of the roller 3 and reduce the damage and wear of the roller 3 caused by the high temperature of the high-temperature slab; and the water droplets after spraying naturally drip onto the guide plate 14, and then can flow into the water tank 13 after passing through the filter 19 along the guide plate 14, and when the water source is reused, the water source can be cooled by the refrigerator 12, so that the cooling effect can be guaranteed while the water resources are reused; and with the help of the drawer rack 18, the impurities or dirt filtered and retained on the filter 19 can be cleaned, so that the impurities or dirt are prevented from flowing back into the water tank 13, and the problem of impurities clogging the nozzle 6 is reduced.
