Description

Technical Field

[0001] This utility model relates to the field of casting roll cooling technology, and in particular to a casting roll cooling device for casting mills. Background Technology

[0002] In the metal rolling process, the casting rolls, as core components, come into direct contact with the high-temperature metal billet and generate a lot of heat during operation. If they cannot be cooled in time and effectively, it will not only affect the quality and precision of the cast and rolled products, but also shorten their service life due to overheating, and even cause equipment failure. Therefore, the cooling device is an indispensable part of the stable operation of the casting roll.

[0003] In the cooling system of the casting rolls of the casting and rolling mill, traditional devices mostly adopt the "one-pass" cooling mode, that is, the cooling water is discharged directly after passing through the internal flow channel or surface spraying, without setting up a special recycling mechanism.

[0004] During the casting and rolling process, the casting rolls need to be continuously cooled to maintain the process temperature. The cooling water only increases in temperature after absorbing heat, and the water quality is not seriously polluted. Direct discharge not only leads to a large waste of water resources, but also requires additional investment in sewage treatment costs to avoid thermal pollution to the surrounding environment due to excessively high water temperature. Therefore, a casting roll cooling device for casting and rolling mills is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cooling device for casting rolls in a casting and rolling mill, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling device for casting rolls in a casting and rolling mill includes a base plate with multiple support legs fixedly installed on its bottom side. The base plate is U-shaped, with two circular holes on each side. Hollow tubes are installed in each of the multiple circular holes. Roll cores are fixedly connected to and communicate with the opposite faces of each pair of hollow tubes. Roll sleeves are fixedly fitted onto the outer sides of each pair of roller cores. A connecting assembly is provided on the opposite sides of each pair of hollow tubes. A water tank is fixedly installed on the bottom side of the base plate, and a partition is fixedly installed inside the water tank. The water tank is divided into two areas by the partition. A water supply assembly and a circulation assembly are respectively provided on both sides of the water tank.

[0008] Preferably, the water delivery assembly includes a water pump fixedly installed on one side of the water tank, an extraction pipe fixedly installed on one side of the water pump, the other end of the extraction pipe extending into the left side area of ​​the water tank, and an inlet pipe fixedly connected to the other side of the water pump.

[0009] Preferably, the connecting assembly includes multiple hollow tubes, each with a limiting groove on its outer side, a sleeve on its outer side, a limiting ring fixedly installed inside each sleeve, and the limiting rings located in the multiple limiting grooves respectively.

[0010] Preferably, a drain pipe is fixedly installed on one side of the water tank and is connected to the water tank. One end of each of the two hollow tubes on the left side is fixedly connected to one side of the water inlet pipe and is connected to the water inlet pipe. One end of each of the two hollow tubes on the right side is fixedly connected to one side of the drain pipe and is connected to the drain pipe.

[0012] Preferably, limiting plates are fixedly sleeved on the outer sides of the two hollow tubes located at the top and bottom, and the side of each pair of limiting plates that is far apart from each other is respectively attached to the inner walls of the two sides of the bottom plate.

[0013] Preferably, a motor is fixedly installed on one inner wall of the base plate. The output end of the motor rotates through the base plate and is fixedly connected to a rotating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The partition inside the water tank divides it into two areas, left and right. Multiple heat dissipation holes in the right area accelerate the discharge of hot air, allowing the cooling water to cool down quickly after absorbing heat. The circulating pump draws the cooled water from the right area through the water pump pipe and delivers it to the left area through the water outlet pipe. Together with the water pump, water inlet pipe, and water outlet pipe, a water circulation is formed, which effectively solves the waste problem caused by the direct discharge of cooling water mentioned in the background technology, reduces water consumption, lowers sewage treatment costs, and avoids thermal pollution.

[0016] 2. The limiting grooves on the outer side of multiple hollow tubes cooperate with the limiting rings inside the sleeve to restrict water overflow and ensure stable water delivery when the hollow tubes rotate. The limiting plates on the outer side of the upper and lower hollow tubes fit against the inner wall of the bottom plate to restrict the left and right displacement of the hollow tubes and ensure the stability of the cooling water flow channel when the roller core rotates.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Refer to Figure 1-4A cooling device for casting rolls in a casting and rolling mill includes a base plate 1. Multiple support legs 21 are fixedly installed on the bottom side of the base plate 1. The base plate 1 is U-shaped, with two circular holes on each side. Hollow tubes 2 are installed within each of the circular holes. A roll core 3 is fixedly connected to and communicates with the opposite faces of every two hollow tubes 2. Roll sleeves 4 are fixedly fitted onto the outer sides of each of the two roll cores 3. A connecting assembly is provided on the opposite faces of every two hollow tubes 2. A water tank 10 is fixedly installed on the bottom side of the base plate 1. A partition is fixedly installed inside the water tank 10, dividing the water tank 10 into two areas. Water supply components and circulation components are respectively installed on both sides of the water tank 10. The connecting components include multiple hollow tubes 2, each with a limiting groove 5 on its outer side. Each hollow tube 2 has a sleeve 6 on its outer side, and each sleeve 6 has a limiting ring 7 fixedly installed inside. The limiting rings 7 are located within the limiting grooves 5. A drain pipe 8 is fixedly installed on one side of the water tank 10, connecting to the water tank 10. Two drain pipes are installed on the left side... One end of each hollow tube 2 is fixedly connected to one side of the inlet pipe 9 and communicates with the inlet pipe 9. One end of each of the two hollow tubes 2 on the right side is fixedly connected to one side of the drain pipe 8 and communicates with the drain pipe 8. The water supply assembly includes a water pump 11 fixedly installed on one side of the water tank 10. An extraction pipe is fixedly installed on one side of the water pump 11. The other end of the extraction pipe extends to the left side area of ​​the water tank 10. The inlet pipe 9 is fixedly connected to the other side of the water pump 11. By setting up the water pump 11, the water pump 11 can be started synchronously during the transportation process, which can drive the extraction pipe to extract the cooling water in the left side area of ​​the water tank 10. Then the cooling water is transported to the two left hollow tubes 2 through the inlet pipe 9. Since the hollow tubes 2 are connected to the roller core 3, the water source can flow along the roller core 3, thereby taking away the heat on the roller sleeve 4. The water source that takes away the heat will flow from the two right hollow tubes 2 into the drain pipe 8. Finally, the water source is transported to the right side area of ​​the water tank 10 through the drain pipe 8. After cooling, it can be recycled.

[0024] Specifically, the circulation assembly includes a circulation pump 13 fixedly connected to one side of the water tank 10, and a water suction pipe 14 and a water outlet pipe 15 fixedly installed on both sides of the circulation pump 13. The other ends of the water suction pipe 14 and the water outlet pipe 15 extend to the left and right sides of the water tank 10, respectively. Multiple heat dissipation holes 12 are provided on both sides of the water tank 10, and the multiple heat dissipation holes 12 are connected to the right side of the water tank 10. By providing multiple heat dissipation holes 12, the heat dissipation holes 12 can accelerate the discharge of hot air, thereby enabling the water source in the right side area to cool down quickly. When the water source in the right side area is cooled down, the circulation pump 13 is started to drive the water suction pipe 14 to draw water from the right side area, and then the water source is transported to the left side area through the water outlet pipe 15, thereby realizing the recycling of water resources.

[0025] Specifically, limiting plates 22 are fixedly sleeved on the outer sides of the two hollow tubes 2 located at the top and bottom. The side of each pair of limiting plates 22 that is far apart from each other is respectively attached to the inner walls of the two sides of the base plate 1. By setting multiple limiting plates 22, the multiple limiting plates 22 can limit the two hollow tubes 2 at the top and bottom, so that they can only rotate and avoid left and right deviation.

[0026] Specifically, a motor 16 is fixedly installed on the inner wall of one side of the base plate 1. The output end of the motor 16 rotates through the base plate 1 and is fixedly connected to a rotating rod 17. A first synchronous pulley 18 is fixedly sleeved on the outer side of the rotating rod 17, and a second synchronous pulley 19 is fixedly sleeved on the outer side of the hollow tube 2 located on the upper right. The first synchronous pulley 18 and the second synchronous pulley 19 share the same synchronous belt 20. By setting the motor 16, when it is necessary to cast and roll the material, starting the motor 16 will drive the rotating rod 17 to rotate. Since the first synchronous pulley 18 is fixedly sleeved on the outer side of the rotating rod 17, and the first synchronous pulley 18 and the second synchronous pulley 19 share the same synchronous belt 20, under the meshing transmission of the synchronous belt 20, the second synchronous pulley 19 drives the hollow tube 2 connected to it to rotate, thereby causing the roller core 3 fixedly connected to the hollow tube 2 to rotate synchronously. At this time, the material to be cast and rolled is placed between the two roller sleeves 4, and then the two rotating roller cores 3 can realize the conveying of the material.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0028] In use: Starting the motor 16 will drive the rotating rod 17 to rotate. Since the first synchronous pulley 18 is fixedly sleeved on the outside of the rotating rod 17, and the first synchronous pulley 18 and the second synchronous pulley 19 are meshed and driven by the same synchronous belt 20, the second synchronous pulley 19 will synchronously drive the hollow tube 2 connected to it to rotate, thereby causing the roller core 3 fixedly connected to the hollow tube 2 to rotate synchronously. At this time, the material to be cast and rolled is placed between the two roller sleeves 4, and the rotating roller core 3 can realize the conveying of the material. During the material conveying process, the water pump 11 is started synchronously. The water pump 11 will draw cooling water from the left area of ​​the water tank 10 through the extraction pipe, and then the cooling water is transported to the two hollow tubes 2 on the left side through the water inlet pipe 9. Connected to the roller core 3, the cooling water flows along the roller core 3, thereby carrying away the heat on the roller sleeve 4. The cooled water that has absorbed heat flows from the two hollow tubes 2 on the right side into the drain pipe 8, and is finally transported to the right side area of ​​the water tank 10 through the drain pipe 8. After cooling, it can be recycled. In addition, multiple heat dissipation holes 12 are provided on the right side area of ​​the water tank 10. These heat dissipation holes 12 can accelerate the discharge of hot air and make the cooling water in the right side area cool down quickly. At the same time, the device is equipped with multiple sleeves 6, and each sleeve 6 is fixedly installed with a limit ring 7. The limit ring 7 is embedded in the limit groove 5 opened in the multiple hollow tubes 2. This structure can not only prevent the water source from overflowing during the transportation process, but also ensure that the multiple hollow tubes 2 can stably transport cooling water during rotation.
