Description

Technical Field

[0001] This utility model relates to the field of continuous casting machine technology, specifically to a single-section roller for the sector section of a continuous casting machine. Background Technology

[0002] In the steel production process, most of the single-section rolls in the sector section of the continuous casting machines currently in use are integral structures with cooling water holes drilled in the middle. Because the cooling water only passes through the middle of the single-section roll, the cooling intensity is low, and the high temperature generated by the contact between the roll sleeve and the continuously cast billet cannot be sufficiently cooled and reduced, resulting in a short service life of the roll sleeve. Utility Model Content

[0003] The purpose of this utility model is to provide a single-section roller for the sector section of a continuous casting machine, so as to improve the cooling intensity of the single-section roller, enable the high temperature generated by the contact between the roller sleeve and the continuous casting billet to be fully cooled and reduced, and improve the service life of the roller sleeve.

[0004] The single-section roller for the sector section of a continuous casting machine provided by this utility model includes a roller sleeve and a cooling water pipe. The cooling water pipe is arranged in the middle of the roller sleeve, and a connecting shaft one and a connecting shaft two are respectively arranged at both ends of the roller sleeve. A water connecting pipe is arranged inside the roller sleeve. A cooling water chamber is arranged inside the connecting shaft one, and a return water channel one is arranged on the connecting shaft one, which is connected to the cooling water chamber. A cooling water channel is arranged inside the connecting shaft two, and a rotary joint is arranged at one end of the connecting shaft two. A return water channel two is arranged on the connecting shaft two, which is connected to the cooling water channel. A return water groove is arranged on the outside of the water connecting pipe, and the two ends of the return water groove are respectively connected to the return water channel one and the return water channel two. The rotary joint is connected to the cooling water pipe.

[0005] Furthermore, one end of the cooling water pipe is provided with a cooling water inlet, and the other end of the cooling water pipe is an open end, which is located in the cooling water cavity of the connecting shaft.

[0006] Furthermore, a connecting plate is provided at the end of the connecting shaft one, and the connecting shaft one is connected to the bearing seat through the connecting plate.

[0007] Furthermore, a cooling water chamber is provided in the middle of the first connecting shaft, and one end of the first connecting shaft is connected to the roller sleeve by an interference fit; a cooling water channel is provided in the middle of the second connecting shaft, and one end of the second connecting shaft is connected to the roller sleeve by an interference fit.

[0008] Furthermore, two water-blocking rings are provided in the middle of the cooling water pipe, and one end of the cooling water pipe is installed inside the connecting shaft two through a fixed steel plate.

[0009] Furthermore, a fixing block is provided at one end of the rotary joint, and a retaining ring is provided in the middle of the rotary joint. The rotary joint is set inside the connecting shaft two through the fixing block and the retaining ring.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, cooling water enters the cooling water pipe through a rotary joint, and then flows out of the cooling water pipe directly into the cooling water chamber of the connecting shaft. The cooling water is closer to the high-temperature area of ​​the roller sleeve, effectively cooling and reducing the high temperature generated by the contact between the roller sleeve and the continuously cast billet.

[0011] 2. In this invention, the cooling water flows sequentially through the cooling water pipe, return water channel one, return water tank, return water channel two, and cooling water channel before flowing out from the rotary joint. This avoids the existing single-section roller where the cooling water is cooled only through the middle hole, thus enhancing the cooling effect, increasing the cooling intensity of the single-section roller, and extending the service life of the roller sleeve.

[0012] Therefore, this utility model has the positive effects of improving the cooling intensity of a single roller section, enabling the high temperature generated by the contact between the roller sleeve and the continuously cast billet to be fully cooled and reduced, thereby improving the service life of the roller sleeve.

[0014] like Figure 1-7As shown, the single-section roller for the sector section of a continuous casting machine provided by this utility model includes a roller sleeve 3 and a cooling water pipe 5. The cooling water pipe 5 is arranged in the middle of the roller sleeve 3, and a connecting shaft 1 and a connecting shaft 2 4 are respectively arranged at both ends of the roller sleeve 3. A water connecting pipe 2 is arranged inside the roller sleeve 3. A cooling water chamber 11 is arranged inside the connecting shaft 1, and a return water channel 12 is arranged on the connecting shaft 1, and the return water channel 12 is connected to the cooling water chamber 11. A cooling water channel 41 is arranged inside the connecting shaft 2, and a rotary joint 43 is arranged at one end of the connecting shaft 2. A return water channel 22 is arranged on the connecting shaft 2, and the return water channel 22 is connected to the cooling water channel 41. A return water groove 21 is arranged on the outside of the water connecting pipe 2, and the two ends of the return water groove 21 are respectively connected to the return water channel 12 and the return water channel 22. The rotary joint 43 is connected to the cooling water pipe 5.

[0015] In use, this invention first introduces cooling water into the cooling water pipe 5 through the rotary joint 43. The cooling water then flows out of the cooling water pipe 5 and directly into the cooling water chamber 11 of the connecting shaft 1. Next, the cooling water flows from the return water channel 12 through the return water groove 21 and the return water channel 2 42 into the cooling water channel 41 of the connecting shaft 4. Finally, the cooling water flows out from the rotary joint 43. This allows the cooling water to be closer to the high-temperature area of ​​the roller sleeve 3, effectively cooling and reducing the high temperature generated by the contact between the roller sleeve 3 and the continuously cast billet. This avoids the problem of existing single-section rollers where the cooling water only passes through the central hole, thus improving the cooling intensity of the single-section roller and extending the service life of the roller sleeve.

[0016] like Figure 1 , 7 As shown, one end of the cooling water pipe 5 is provided with a cooling water inlet 51, and the other end of the cooling water pipe 5 is an open end 52, which is located in the cooling water chamber 11 of the connecting shaft 1. Cooling water enters from the cooling water inlet 51 of the cooling water pipe 5 and flows out from the open end 52 of the cooling water pipe 5, allowing the cooling water to flow directly into the cooling water chamber 11 of the connecting shaft 1. The cooling water is closer to the high-temperature area of ​​the roller sleeve 3, which can fully cool and reduce the high temperature generated by the contact between the roller sleeve and the continuously cast billet, thereby improving the service life of the roller sleeve.

[0017] like Figure 1 , 3 As shown, a connecting plate 13 is provided at the end of the connecting shaft 1, and the connecting shaft 1 is connected to the bearing housing through the connecting plate 13. The device can be directly installed on the bearing and bearing housing through the connecting plate 13 and bolts, which is convenient for installation.

[0018] like Figure 1-5As shown, a cooling water chamber 11 is provided in the middle of the connecting shaft 1. One end of the connecting shaft 1 is connected to the roller sleeve 3 by an interference fit. The cooling water in the cooling water chamber 11 can cool the connecting shaft 1, thereby cooling the high-temperature area of ​​the roller sleeve 3. A cooling water channel 41 is provided in the middle of the connecting shaft 4. One end of the connecting shaft 4 is connected to the roller sleeve 3 by an interference fit. The cooling water in the cooling water channel 41 can cool the connecting shaft 4, thereby cooling the high-temperature area of ​​the roller sleeve 3. This allows the high temperature generated by the contact between the roller sleeve and the continuous casting billet to be fully cooled and reduced, thereby improving the service life of the roller sleeve.

[0019] like Figure 1 , 7 As shown, two water-blocking rings 53 are provided in the middle of the cooling water pipe 5, and one end of the cooling water pipe 5 is installed in the connecting shaft 4 through a fixing steel plate 54. The water-blocking rings 53 can prevent the cooling water from flowing back and avoid affecting the cooling effect of the roller sleeve 3.

[0020] like Figure 1 , 5 As shown in Figure 7, a fixing block 44 is provided at one end of the rotary joint 43, and a retaining ring 45 is provided in the middle of the rotary joint 43. The rotary joint 43 is set inside the connecting shaft 2 4 through the fixing block 44 and the retaining ring 45. Cooling water enters from the rotary joint 43, passes through the cooling water pipe 5, the first return water channel 12, the return water tank 21, the second return water channel 42, and the cooling water channel 41 in sequence, and then flows out from the rotary joint 43, so that the cooling water is closer to the high temperature area of ​​the roller sleeve 3, thereby enhancing the cooling effect.

[0021] The technical solution of this utility model is not limited to the scope of the embodiments described in this utility model. All technical contents not described in detail in this utility model are known technologies.
