Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel castings, and specifically relates to a high-temperature resistant stainless steel casting. Background Technique

[0002] High-temperature resistant stainless steel castings are parts used for transporting high-temperature fluids. During use, they have high requirements for high-temperature resistance. Under long-term high-temperature conditions, traditional materials are easily damaged or aged. Existing high-temperature resistant stainless steel castings usually do not have heat dissipation properties and still remain in a high-temperature state. Although high-temperature resistant stainless steel castings can withstand the high temperature of the transported liquid, the excessive temperature will still age the casting body and shorten the service life of high-temperature resistant stainless steel castings.

[0003] After retrieval, a Chinese patent with the publication number CN218883344U discloses a high-temperature resistant stainless steel casting, which includes a stainless steel casting main body. An external connecting pipe is provided on the stainless steel casting main body. A welding top plate is welded to the top of the stainless steel casting main body. A plurality of internal heat conduction plates are fixedly connected to the bottom of the welding top plate. A heat dissipation fin installation base is provided on the top of the stainless steel casting main body. A docking base is movably clamped inside the heat dissipation fin installation base, and a heat dissipation fin main body is connected to the docking base.

[0004] This casting uses the provided welding top plate, internal heat conduction plates, heat dissipation fin installation base, docking base, heat dissipation fin main body and locking mechanism to conveniently install a heat dissipation fin main body on the top of the stainless steel casting main body to dissipate heat from the stainless steel casting main body, so that while the stainless steel casting main body has high-temperature resistance, it has good heat dissipation and is not easily damaged or aged.

[0005] However, this casting still has the following problems. The casting facilitates the derivation of heat from the casting main body through the mutual cooperation between the internal heat conduction plates and the heat dissipation fins. The internal heat conduction plates are fixedly connected to the bottom of the welding top plate, the welding top is fixedly connected to the top of the casting main body, the heat dissipation fins are fixedly connected to the heat dissipation fin main body by a clamping method, and the heat dissipation fin main body is also fixedly connected to the top of the casting main body. Therefore, the top of the casting main body dissipates heat faster, while the two sides and the bottom of the casting main body dissipate heat slower than the top, making it difficult to effectively improve the heat dissipation efficiency of the casting.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment: As Figure 1 shown, a high-temperature resistant stainless steel casting includes a casting body 1, and the casting body 1 is cast from stainless steel material to improve the overall structural strength and service life of the casting. One end of the casting body 1 is fixedly connected with a first flange 2, and the other end of the casting body 1 is fixedly connected with a second flange 3. Through the setting between the first flange 2 and the second flange 3, the sealing performance of the casting connection is improved. It also includes a heat dissipation component arranged on the outer peripheral wall of the casting body 1, and a heat insulation component is arranged inside the casting body 1.

[0025] As Figure 2 And Figure 3As shown, in a certain embodiment, in order to improve the heat dissipation efficiency of the casting, the heat dissipation component includes a set of first connection holes 4 opened at one end of the first flange 2. A set of second connection holes 5 are opened at one end of the second flange 3. The arrangement of the first connection holes 4 and the second connection holes 5 facilitates connection and at the same time increases the heat dissipation area of the first flange 2 and the second flange 3. A set of through grooves 11 are opened at one end of the casting body 1 near the first flange 2. The through grooves 11 increase the surface area of the casting body 1, thereby increasing the heat dissipation area of the casting body 1. And one end of each through groove 11 is communicated with the adjacent first connection hole 4. The inner wall of each through groove 11 is fixedly connected with a heat dissipation rod 12. Through the mutual cooperation between the heat dissipation rod 12, the through groove 11 and the first connection hole 4, the heat of the casting body 1 is transferred to the heat dissipation rod 12 and then released to the external environment through the heat dissipation rod 12. A number of evenly distributed first heat dissipation fins 6 are fixedly connected to the outer peripheral wall of the casting body 1 near the through grooves 11. A number of evenly distributed second heat dissipation fins 7 are fixedly connected to the outer peripheral wall of the casting body 1 near the second flange 3. Through the mutual cooperation between the first heat dissipation fins 6 and the second heat dissipation fins 7, the heat dissipation area of the casting body 1 is further increased. One ends of a number of the first heat dissipation fins 6 are commonly fixedly connected to a first heat dissipation ring 8, and the inner peripheral wall of the first heat dissipation ring 8 is fixedly connected to the outer peripheral wall of the casting body 1. One ends of a number of the second heat dissipation fins 7 are commonly fixedly connected to a second heat dissipation ring 10, and the inner peripheral wall of the second heat dissipation ring 10 is fixedly connected to the outer peripheral wall of the casting body 1. One end of the first heat dissipation ring 8 and one end of the second heat dissipation ring 10 are commonly fixedly connected to a spiral fin 9. Through the mutual cooperation between the first heat dissipation ring 8, the second heat dissipation ring 10 and the spiral fin 9, the heat dissipation efficiency of the casting is effectively improved, thereby improving the high-temperature resistance performance and service life of the casting.

[0026] As Figure 3 with Figure 4 As shown, in a certain embodiment, in order to further improve the high-temperature resistance performance of the casting, the heat insulation component includes a heat insulation pipe 13 fixedly communicated with the inner peripheral wall of the casting body 1. The heat insulation pipe 13 includes a connecting pipe 1301, and the outer peripheral wall of the connecting pipe 1301 is fixedly connected to the inner peripheral wall of the casting body 1. The inner peripheral wall of the connecting pipe 1301 is provided with a heat insulation layer 1302 by coating. The heat insulation layer 1302 plays a role in isolating the heat transfer to the casting body 1. The inner peripheral wall of the heat insulation layer 1302 is provided with a high-temperature resistant layer 1303 by coating. Through the setting of the high-temperature resistant layer 1303, the service life of the heat insulation pipe 13 in a high-temperature working environment is improved.

[0027] Working principle: When in use, first fixedly connect the heat dissipation rod 12 in the through groove 11, and then fixedly connect the first flange 2 and the second flange 3 to both ends of the casting body 1 by welding, which is convenient for improving the connection stability and sealing performance between the casting body 1 and other working components. Through the mutual cooperation among the heat dissipation rod 12, the through groove 11 and the first connection hole 4, the heat of the casting body 1 is transferred to the heat dissipation rod 12 and then released to the external environment through the heat dissipation rod 12. At the same time, the heat dissipation rod 12 plays a role in strengthening the casting body 1 to prevent the casting body 1 from deforming in a high-temperature working environment. Then, through the mutual cooperation among the first heat dissipation fin 6, the second heat dissipation fin 7, the first heat dissipation ring 8, the spiral fin 9 and the second heat dissipation ring 10, the heat dissipation area of the casting body 1 is increased, effectively improving the heat dissipation efficiency of the casting body 1, thereby enhancing the high-temperature resistance performance of the casting. At the same time, through the arrangement of the heat insulation pipe 13 fixedly communicated with the inner peripheral wall of the casting body 1, the heat insulation effect of the casting is effectively improved. Through the mutual cooperation between the connecting pipe 1301 and the heat insulation layer 1302, heat transfer to the casting body 1 is avoided. Then, through the arrangement of the high-temperature resistant layer 1303, the heat insulation effect and service life of the heat insulation pipe 13 are improved.
