Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooling devices, in particular to a roughing roller table with a cooling device. Background Art
[0002] In a rolling mill, the roller is the most frequently used equipment component. Particularly in the roughing mill, the roller comes into direct contact with hot steel (typically around 1100°C), causing the roller temperature to rise rapidly. To ensure the strength of the roll surface and maintain the mounting within a safe temperature range, the roller must be effectively and rapidly cooled. Failure to dissipate this heat can lead to deformation and bending of the rolling track, severely impacting its service life and even forcing the mill to shut down. Therefore, proper cooling of the rolling roller is crucial.
[0003] The patent with the current announcement number CN215314718U discloses a roughing mill roller with a cooling device, including a roller body, a cooling pipe inside the roller body, and the cooling pipe is connected to the liquid inlet pipe and the liquid outlet pipe respectively. One end of the roller body is sealed and connected to the motor, and the other end is provided with an opening. A closing plate is detachably connected to the outer side of the opening. A through hole is provided in the middle of the closing plate, and the liquid inlet pipe and the liquid outlet pipe are provided through the through hole. The two ends of the roller body are connected to the mounting seat respectively with bearings. The liquid inlet pipe and the liquid outlet pipe are fixedly connected to the mounting seat. The lower end of the mounting seat is fixedly connected to the fixed seat. A spray pipe is provided below the roller body, and the spray pipe is provided with a nozzle. It adopts dual internal and external cooling, and internal double-helix pipe cooling. The roller body does not require high sealing requirements. The refluxed coolant can enter the circulation again. According to the actual temperature of the roller body during operation, fan-shaped nozzles are used on the outside to achieve more uniform cooling. The remaining coolant is recycled and reused to save costs.
[0004] However, the roughing roller in the above technology still has the following problems: during the roughing rolling process of the roughing roller on the rolled steel, the roller surface needs to be in direct contact with the rolled steel, and only a single nozzle is used for spray cooling on the outside of the roller, which cannot achieve uniform cooling of the roller surface, which may lead to untimely local cooling of the roller surface, causing partial deformation and bending of the roller, affecting the service life of the roller.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0026] See also Figures 1 to 7, a roughing roller with a cooling device, comprises a roller body 2 installed in a U-shaped base 1, a water storage tank 101 is opened on the bottom inner wall of the U-shaped base 1, a filter assembly is connected to the water storage tank 101, and a plurality of arc-shaped cooling pipes 3 are provided on the side of the roller body 2 close to the water storage tank 101, two support rods 4 are fixedly connected to the inner walls on both sides of the U-shaped base 1, and both ends of the plurality of arc-shaped cooling pipes 3 are respectively fixedly connected to the two support rods 4, and the plurality of arc-shaped cooling pipes 3 are fixedly connected to the side close to the roller body 2 and are connected to a plurality of nozzles 5, and the bottom of the plurality of arc-shaped cooling pipes 3 is connected to a water injection assembly, and the other end of the water injection assembly is located in the water outlet tank 101, and one side of the roller body 2 is connected to a wiper assembly, and the wiper assembly is located above one end of the plurality of arc-shaped cooling pipes 3.
[0027] like Figures 1 to 7 As shown, the roughing roller with a cooling device in the present invention is similar to the existing roughing roller with a cooling device, such as the roughing roller with a cooling device disclosed in the patent publication number CN215314718U. The main improvement of the present invention is that the user can save more lubricating oil added to the roughing roller with a cooling device. Figures 1 to 7 As shown, when the rough rolling roller with a cooling device in the present invention is in use, coolant is injected into the multiple arc-shaped cooling tubes 3 through the water injection component, and then the coolant is sprayed on the roller body 2 more evenly through the multiple nozzles 5 installed on the inner side of the arc-shaped cooling tube 3, thereby reducing the temperature of the roller body 2. At the same time, the coolant attached to the rotating roller body 2 can be scraped off by the wiper component, thereby preventing the coolant attached to the surface of the roller body 2 from contacting the rolled steel with the rotation of the roller body 2, affecting the rolling quality, and the scraped coolant and the coolant dripping from the roller body 2 fall back into the water storage tank 101 for repeated recycling, reducing the waste of coolant.
[0028] like Figures 3 to 5 As shown, the water injection assembly includes a water pump 6 and a water injection pipe 7. The water pump 6 is fixedly connected to the inner wall of one side of the U-shaped base 1 through a mounting base. The water inlet end of the water pump 6 extends downward to the bottom of the water storage tank 101. The water outlet end of the water pump 6 is fixedly connected to and communicates with the water injection pipe 7. The two ends of the water injection pipe 7 are respectively fixedly connected to the two sides of the U-shaped base 1. The side walls of the water injection pipe 7 are fixedly connected to and communicate with a plurality of water distribution pipes 8. The other ends of the plurality of water distribution pipes 8 are respectively fixedly connected to and communicate with a plurality of arc-shaped cooling pipes 3. The coolant in the water storage tank 101 is pumped into the water injection pipe 7 by the water pump 6, and then pumped into the plurality of water distribution pipes 8 and the plurality of arc-shaped cooling pipes 3 by the water injection pipe 7. Then, it is sprayed from the nozzle 5 onto the roller body 2 to form a cooling effect.
[0029] like Figures 3 to 5As shown, a solenoid valve 9 is fixedly mounted on the outer wall of the water distribution pipe 8. Installing a solenoid valve 9 on each water distribution pipe 8 allows for free control over whether cooling spray is required in each water distribution pipe 8. When the steel material rolled on the roller body 2 is narrow, the solenoid valve 9 can be used to close part of the water distribution pipe 8, allowing the roller body 2 to be cooled using part of the arc-shaped cooling pipe 3, thereby reducing the energy consumption of the cooling spray. The solenoid valve 9 can be controlled to be open or closed by a temperature sensor or manually.
[0030] like Figures 1 to 4 As shown, the filter assembly includes a filter plate 10 and a filter element 11. The surface of the filter plate 10 is penetrated by a plurality of water-permeable holes 102. The filter plate 10 is connected to the inner wall of the water tank 101. The filter element 11 is located on the upper surface of the filter plate 10 and is slidably connected to the inner wall of the water tank 101. The water inlet of the water pump 6 passes through the filter element 11 and the adjacent water-permeable holes 102 and then extends to the bottom of the water tank 101. During the rolling of the roller body 2, some waste residue may fall from the rolled steel. When this waste residue falls into the water tank 101 below, it can be filtered by the filter element 11 installed on the filter plate 10, thereby allowing only the coolant to fall back into the water tank 101, while the solid impurities are retained on the filter element 11, ensuring that the coolant in the water tank 101 remains clean and preventing the impurities from clogging the water pump 6.
[0031] like Figures 2 to 4 As shown, a mounting ring 12 is fixedly connected to the inner wall of the water tank 101. The bottom circumference of the filter plate 10 abuts against the mounting ring 12, and the filter plate 10 is slidably connected to the water tank 101. When installing the filter plate 10, the filter plate 10 is placed on the mounting ring 12 in the water tank 101. This facilitates the removal and installation of the filter plate 10 and the filter element 11 in the water tank 101, and facilitates the cleaning of filtered impurities on the filter element 11.
[0032] like Figure 1 and Figure 6 As shown, the scraping assembly includes a mounting rod 13 and a scraping bar 14. The mounting rod 13 is located above one end of the plurality of arc-shaped cooling tubes 3. The two ends of the mounting rod 13 are fixedly connected to the two sides of the U-shaped base 1. The scraping bar 14 is connected to the side of the mounting rod 13 close to the roller body 2, and the other side of the scraping bar 14 abuts against the roller body 2. The scraping bar 14 is mounted on the inner side of the mounting rod 13 fixed to the U-shaped base 1. When the roller body 2 rotates, the scraping bar 14 scrapes off the coolant adhering to the surface of the roller body 2 and drips downward into the water storage tank 101, preventing the adhering coolant from coming into contact with the hot rolled steel material and causing damage to the steel material. When the roller body 2 rotates, it rotates upward from the bottom of the scraping bar 14.
[0033] like Figure 1 、 Figure 6 and Figure 7As shown, the side of the mounting rod 13 away from the roller body 2 is penetrated by a plurality of limiting holes 103. Limiting rods 15 are slidably connected to each of the limiting holes 103. A mounting bar 16 is fixedly connected to the end of each of the limiting rods 15 near the roller body 2. The other side of the mounting bar 16 is connected to the scraper bar 14. Extrusion springs 17 are connected to the outer sides of each of the limiting rods 15. The extrusion springs 17 are respectively sleeved around the limiting rods 15. The ends of the extrusion springs 17 are respectively fixedly connected to the mounting bar 16 and the mounting rod 13. The scraper bar 14 is mounted on the mounting bar 16. The mounting bar 16 is squeezed and pushed toward the side wall of the roller body 2 by the limiting rod 15 and the extrusion spring 17, thereby enabling the scraper bar 14 to better scrape away the coolant adhering to the surface of the roller body 2, thereby improving the scraping effect.
[0034] like Figure 6 and Figure 7 As shown, a mounting groove 104 is formed on the side of the mounting strip 16 away from the mounting rod 13, and the scraper strip 14 is slidably connected to the mounting groove 104. By forming the mounting groove 104 on the side wall of the mounting strip 16, the scraper strip 14 can be easily removed from the mounting groove 104 and replaced after long-term use, thereby ensuring the scraper strip 14 has a good scraping and cleaning effect on the roller body 2.
[0035] like Figure 6 and Figure 7 As shown, the end of the limiting rod 15 away from the mounting bar 16 is fixedly connected to an anti-slip block 18, which abuts against the side of the mounting rod 13 away from the roller body 2. The anti-slip block 18 can prevent the limiting rod 15 and the mounting rod 13 from falling off when the extrusion spring 17 rebounds, thereby improving the connection stability.
[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
