[0021] The following will be combined with the drawings in the specification of the embodiment of the present invention to clearly and completely describe the technical solutions in the embodiment of the present invention. Obviously, the embodiment described is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 3, the utility model provides an embodiment: a slab continuous casting fan-shaped segment roller seat cooling water circuit, including a base 1, a water inlet pipe 3 is installed on the side end surface of one side of the base 1, and a flow control valve 11 is installed on the outer wall of the water inlet pipe 3. The flow control valve 11 is located on the outside of one side of the base 1. The flow control valve 11 can control the flow of cooling water entering the first cooling water pipe 12. A first cooling water pipe 12 is arranged inside the base 1, and the first cooling water pipe 12 is serpentine. A second cooling water pipe 13 is arranged inside the base 1, and a third cooling water pipe 14 is arranged outside the second cooling water pipe 13. The first cooling water pipe 12 is located inside the second cooling water pipe 13, and one end of the first cooling water pipe 12 is connected to one end of the water inlet pipe 3. The second cooling water pipe 13 and the third cooling water pipe 14 are both ring-shaped. The other end is connected to the second cooling water pipe 13, and the third cooling water pipe 14 is connected to the second cooling water pipe 13 through several second connecting pipes 19. Three second heat conduction plates 16 are arranged inside the base 1, and the three second heat conduction plates 16 are all located inside the first cooling water pipe 12. Two symmetrically arranged first heat conduction plates 15 are arranged between the second cooling water pipe 13 and the third cooling water pipe 14. The first heat conduction plate 15 and the second heat conduction plate 16 are both made of graphene material, which is used to transfer heat between the first cooling water pipe 12 and between the second cooling water pipe 13 and the third cooling water pipe 14, so that the heat is quickly extracted. An outlet pipe 4 is installed on the outer wall of the third cooling water pipe 14, and the water inlet pipe 3 and the water outlet pipe 4 are located on the same side end of the base 1, and the water outlet pipe 4 is lower than the water inlet pipe 3. A circulation component is provided on the outside of one side of the base 1.

[0023] Specifically, the external cooling water flows into the first cooling water pipe 12 through the water inlet pipe 3, then flows into the second cooling water pipe 13 from the first cooling water pipe 12, then flows to the third cooling water pipe 14 through several second connecting pipes 19, and finally flows out from the water outlet pipe 4. The layered surrounding design of the serpentine first cooling water pipe 12 and the annular second cooling water pipe 13 and the third cooling water pipe 14 can increase the contact area between the cooling water and the roller seat base 1, reduce the existence of dead corners, avoid local overheating, and is conducive to cooling uniformity, and can improve the cooling effect and heat exchange capacity, thereby effectively improving the cooling effect.

[0024] The circulation component includes a first connecting pipe 9 connected to one end of the water inlet pipe 3, and the water inlet pipe 3 and the first connecting pipe 9 are connected through a water pipe joint 5. A refrigerator 6, a water storage tank 7 and a circulating water pump 8 are arranged on the outside of the base 1. The other end of the first connecting pipe 9 is connected to the output end of the circulating water pump 8, and the input end of the circulating water pump 8 is connected to one end of the water outlet of the water storage tank 7. The water inlet of the water storage tank 7 is connected to the water outlet of the refrigerator 6 through another first connecting pipe 9, and the water inlet of the refrigerator 6 is connected to one end of the water outlet pipe 4. The water outlet pipe 4 is connected to the water inlet of the refrigerator 6 through another water pipe joint 5. The water pipe joint 5 can conveniently connect and disassemble the first connecting pipe 9 with the water inlet pipe 3, the water inlet of the refrigerator 6 and the water outlet pipe 4, so as to facilitate the replacement of cooling water and maintenance of pipe fittings.

[0025] Specifically, the cooling water that has lost its cooling capacity is pumped out from the water outlet pipe 4 through the circulating water pump 8, and then flows into the refrigerator 6, the temperature of the cooling water is lowered again, and then flows into the water storage tank 7, and then flows from the water storage tank 7 to the water inlet pipe 3. The circulating water pump 8 can keep the cooling water flowing. This setting is conducive to the circulation of cooling water, avoids water waste, and is conducive to the flow of cooling water, so as to improve the cooling efficiency and cooling effect.

[0026] The upper end surface of the base 1 is fixedly connected to the two side plates 2, and a cooling chamber 20 is arranged inside the side plates 2. Both sides of the upper end surface of the base 1 are fixedly connected to the water pump 10. The input end of the water pump 10 is connected to the second cooling water pipe 13 through a second connecting water pipe 18, and the output end of the water pump 10 is connected to one end of the cooling chamber 20 through another second connecting water pipe 18. The other end of the cooling chamber 20 is connected to the first connecting pipe 17, and the end of the first connecting pipe 17 away from the cooling chamber 20 is connected to the second cooling water pipe 13.

[0027] Specifically, the cooling water in the second cooling water pipe 13 can be pumped into the cooling cavity 20 of the side plate 2 by the water pump 10 , and then flows into the second cooling water pipe 13 through the first connecting pipe 17 , thereby completing the cooling of the side plate 2 .

[0028] Working principle: The cooling water in the water storage tank 7 flows into the water inlet pipe 3 through the circulating water pump 8, and then flows into the first cooling water pipe 12, and then flows into the second cooling water pipe 13, and then flows into the cooling cavity 20 of the side plate 2 through the water pump 10, and then flows back into the second cooling water pipe 13 through the first connecting pipe 17, and then guides the cooling water to the third cooling water pipe 14 through several second connecting pipes 19. Finally, the cooling water that has lost its cooling capacity is introduced into the refrigerator 6 by the water outlet pipe 4, so that the cooling water regains its cooling capacity, and finally flows into the water storage tank 7 for storage.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
