Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting rollers, and more specifically, to a sector-shaped continuous casting roller. Background Art

[0002] The fan-shaped continuous casting roller is an important equipment in the continuous casting machine. Its function is to continuously cast molten steel into billets. During the continuous casting process, the fan-shaped segment roller is in direct contact with the high-temperature billet, and the working environment is very harsh. The fan-shaped continuous casting roller needs to be made of high-temperature alloy materials to ensure its high temperature resistance, wear resistance and deformation resistance. In order to reduce the temperature of the fan-shaped continuous casting roller, a cooling device is usually provided. The cooling device has an important influence on the life and performance of the fan-shaped continuous casting roller. Most of the existing continuous casting roller cooling methods use water cooling. A cooling water pipe is provided inside the continuous casting roller, so that the cooling water circulates on the inner wall of the cooling water pipe, thereby reducing the temperature of the continuous casting roller. Although this method can achieve the cooling of the continuous casting roller, since the temperature of the continuous casting roller is usually above one thousand degrees Celsius, the single water cooling method is incapable of doing so, resulting in a slow cooling rate of the continuous casting roller, thereby reducing its cooling efficiency to a certain extent. In order to address the deficiencies of the prior art, we propose a fan-shaped segment continuous casting roller. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a sector-shaped continuous casting roller to solve the problem that the temperature of the continuous casting roller is usually above one thousand degrees Celsius, which makes the single water cooling method incapable of meeting the requirements, resulting in a slow cooling rate of the continuous casting roller, thereby reducing its cooling efficiency to a certain extent.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a sector-shaped continuous casting roller, comprising two support seats, a cooling assembly is arranged between the two support seats, and a slotting assembly is arranged on the lower side of the cooling assembly;

[0009] Wherein, an exhaust pipe is arranged on one side of the heat dissipation sleeve, and the exhaust pipe is arranged on the inner wall of the support seat, and the diameter of the exhaust pipe is equal to the diameter of the circle formed by the multiple through holes.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model provides a cooling assembly including a fan. The roller absorbs a large amount of heat during operation, so that the roller has a relatively high temperature. At this time, the heat dissipation sleeve absorbs the heat inside the roller. Then, the fan is started to suck the external cold air into the roller through the through hole to absorb the heat of the heat dissipation sleeve and discharge it from the other end of the heat dissipation sleeve. In addition, cooling water is injected from the lower end of one side of the cooling pipe to absorb the heat of the heat dissipation sleeve and discharge it from the lower end of the other side of the cooling pipe. With the above structure, by starting the fan and injecting cooling water into the cooling pipe, a two-stage cooling effect on the roller is achieved, which greatly accelerates the cooling rate of the roller, thereby improving the cooling efficiency of the roller.

[0012] The utility model provides a slotting component, including a base, which is fixedly mounted on the lower outer surface of the support seat, so that the upper outer surface of the tooth block is arranged inside the annular groove, and the roller body rotates so that the upper outer surface of the tooth block slides on the outer wall of the annular groove. By utilizing the above structure, an annular groove is opened on the outer surface of the roller body, and the tooth block is slidably connected to the outer wall of the annular groove, impurities on the inner wall of the annular groove are continuously cleaned to prevent the annular groove from being filled with impurities, which not only increases the friction force of the outer surface of the roller body, but also achieves the effect of increasing the wear resistance of the roller body.

[0021] The cooling assembly 2 includes a fan 21, a cooling pipe 22 is arranged on one side of the fan 21, a first limit block 23 is fixedly sleeved on the outer wall of one end of the cooling pipe 22, a second limit block 24 is arranged on the outer wall of the other end of the cooling pipe 22, a heat dissipation sleeve 25 is fixedly sleeved on the outer wall of the cooling pipe 22, and a through hole 26 is opened inside the heat dissipation sleeve 25.

[0022] The fan 21 is fixedly mounted on the outer surface of one side of the support base 1, the first limit block 23 is clamped on the inner wall of one end of the heat dissipation sleeve 25, and the second limit block 24 is clamped on the inner wall of the other end of the heat dissipation sleeve 25;

[0023] The roller body 35 absorbs a large amount of heat during operation, so that the roller body 35 has a relatively high temperature. At this time, the heat dissipation sleeve 25 absorbs the heat inside the roller body 35, and then the fan 21 is started to suck the external cold air into the roller body 35 through the through hole 26 to absorb the heat of the heat dissipation sleeve 25 and discharge it from the other end of the heat dissipation sleeve 25, and cooling water is injected from the lower end of one side of the cooling pipe 22 to absorb the heat of the heat dissipation sleeve 25 and discharge it from the lower end of the other side of the cooling pipe 22, thereby realizing the two-stage cooling of the roller body 35, greatly accelerating the cooling rate of the roller body 35, and thus improving the cooling efficiency of the roller body 35.

[0024] The slotting assembly 3 includes a base 31, a bottom plate 32 is fixedly mounted on the upper outer surface of the base 31, a backing plate 33 is fixedly mounted on the upper outer surface of the bottom plate 32, a tooth block 34 is fixedly mounted on the upper outer surface of the backing plate 33, a roller body 35 is slidably connected to the upper outer surface of the tooth block 34, an annular groove 36 is formed on the outer surface of the roller body 35, the base 31 is fixedly mounted on the lower outer surface of the two support seats 1, the tooth block 34 is attached to the outer wall of the annular groove 36, and the roller body 35 is attached to the outer wall of the heat dissipation sleeve 25;

[0025] By fixing the base 31 on the lower outer surface of the support seat 1, the upper outer surface of the tooth block 34 is set inside the annular groove 36. The roller body 35 rotates so that the upper outer surface of the tooth block 34 slides on the outer wall of the annular groove 36, thereby continuously cleaning the impurities on the inner wall of the annular groove 36, which not only increases the friction force of the outer surface of the roller body 35, but also increases the wear resistance of the roller body 35.

[0026] The cooling pipe 22 is arranged at the inner center of the roller body 35 , and the fan 21 and the cooling pipe 22 are on the same horizontal axis.

[0027] Among them, an exhaust pipe is provided on one side of the heat dissipation sleeve 25, and the exhaust pipe is provided on the inner wall of the support seat 1, and the diameter of the exhaust pipe is equal to the diameter of the circle formed by the plurality of through holes 26;

When the roller body 35 is working, the roller body 35 absorbs a lot of heat during the working process, so that the roller body 35 has a high stability.
