Description

Technical Field

[0001] This utility model belongs to the field of steel wire manufacturing technology, and in particular to a steel wire cooling device. Background Technology

[0002] When steel wire is processed at high temperatures, such as during heat treatment and wire drawing, its internal structure is in an unstable state. Rapid cooling and other methods are needed to refine the grains to improve the mechanical properties of the steel wire, such as strength, hardness, and toughness, in order to meet the performance requirements of steel wire in different application scenarios.

[0003] However, existing cooling methods are slow, and at high temperatures, the carbon in the steel wire easily reacts with oxygen in the air, leading to decarburization. This reduces the hardness and strength of the steel wire and causes oxide scale or rust to form on its surface. Therefore, how to rapidly cool high-temperature processed steel wire without causing oxidation and decarburization is a problem that needs to be solved. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a steel wire cooling device to solve the problem of how to quickly cool steel wire processed at high temperatures and prevent oxidation and decarburization.

It is used to form a cooling water circulation cavity between the inner cooling tube and the outer cooling tube. The inlet end cap and the outlet end cap are respectively covered and connected to the two end plates. The inlet end cap is in the shape of a boss. A stepped through hole is opened in the inlet end cap. The large hole of the stepped through hole is connected to the inner cooling tube.

Therefore, they should not be construed as limitations on this utility model.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, a steel wire cooling device 100 includes: a bracket 1, a cooling outer tube 2, an end plate 3, a water inlet nozzle 4, a water outlet nozzle 5, a cooling inner tube 6, an inlet end cap 7, an outlet end cap 8, a tapered sleeve 9, and an air pipe connector 10.

[0023] The cooling outer pipe 2 is mounted on the bracket 1.

[0024] Two end plates 3 are provided, which are respectively sealed at the inlet end 21 and the outlet end 22 of the cooling outer pipe 2.

[0025] The water inlet nozzle 4 is inserted and connected to the bottom of the cooling outer tube 2 and is close to the outlet end 22 of the cooling outer tube 2.

[0026] The water outlet 5 is inserted and connected to the top of the cooling outer pipe 2 and close to the inlet end 21 of the cooling outer pipe 2.

[0027] The inner cooling tube 6 is inserted into the outer cooling tube 2, and both ends of the inner cooling tube 6 are respectively inserted and fixed in the two end plates 3, so as to form a cooling water circulation cavity 26 between the inner cooling tube 6 and the outer cooling tube 2.

[0028] The inlet end cap 7 and the outlet end cap 8 are respectively covered and connected to the two end plates 3. The inlet end cap 7 is in the shape of a boss. A stepped through hole 71 is opened in the inlet end cap 7. The large hole of the stepped through hole 71 is connected to the cooling inner tube 6. Ceramic wire nozzles 78 are embedded and fixed in the small hole of the stepped through hole 71 and the outlet end cap 8, respectively, for the steel wire 101 to enter and exit.

[0029] The tapered sleeve 9 is welded and fixed to the outlet end of the cooling outer tube 2 by solder 91, with the cone tip of the tapered sleeve 9 facing the ceramic wire nozzle 78 inside the outlet end cover 8. This facilitates the threading of the steel wire 101.

[0030] The gas pipe connector 10 is inserted into the large hole of the inlet end cap 7 and connects to the stepped through hole 71, for introducing nitrogen gas into the cooling inner tube 6. Nitrogen is an inert gas that, during the cooling process of high-temperature steel wire, isolates it from air, preventing the steel wire from undergoing an oxidation reaction with oxygen in the air, thereby preventing the formation of oxide scale or rust on the surface of the steel wire and maintaining its surface quality and performance. Simultaneously, the forced cooling of the steel wire using a nitrogen gas flow further enhances the cooling effect.

[0031] Optionally, the axial center lines of the outer cooling tube 2 and the inner cooling tube 6 coincide. This results in more even and stable cooling.

[0032] Optionally, the inlet end cap 7 and the outlet end cap 8 are detachably attached to the two end plates 3. This facilitates the disassembly and maintenance of the two end caps.

[0033] Optionally, the cooling inner tube 6, the tapered sleeve 9, and the axial center lines of the two ceramic wire nozzles 78 are aligned. This allows for smoother entry and exit of the steel wire 101.

[0034] Optionally, the inlet nozzle 4 and the outlet nozzle 5 are vertically inserted into the cooling outer tube 2. This makes the water flow smoother.

[0035] Optionally, the inlet nozzle 4 and the outlet nozzle 5 are welded to the cooling outer pipe 2 respectively. This helps to ensure the airtightness of the cooling water circulation cavity.

[0036] Optionally, the endotracheal connector 10 is threaded onto the inlet end cap 7. This facilitates the disassembly and maintenance of the endotracheal connector 10.

[0037] Optionally, both ceramic nozzles 78 are convex, i.e., single-sided ceramic eyes. A pressure cap 72 is also provided at the inlet end cap 7 to press the convexity of the ceramic nozzle 78 located inside the inlet end cap 7 onto the inlet end cap 7. The outlet end cap 8 presses the convexity of the ceramic nozzle 78 at the outlet end cap 8 onto the solder 91 of the tapered sleeve 9. This facilitates the fixing of the two ceramic nozzles 78 and prevents them from being moved by the back-and-forth moving steel wire 101.

[0038] Optionally, the support frame 1 includes two uprights 11 and two adjustable supports 12. Each upright 11 has an adjustable support 12 corresponding to its top side, and the two ends of the cooling outer pipe 2 are respectively mounted on the two adjustable supports 12. This structure is simplified and facilitates the installation of the cooling outer pipe 2.

[0039] Preferably, each adjustable support 12 is fixed to the top side of its corresponding upright 11 in an adjustable manner. This facilitates adjustment according to uneven conditions on site.

[0040] The method of using one embodiment of the steel wire cooling device 100 of this utility model is as follows:

[0041] First, circulating cooling water is continuously introduced through the inlet nozzle 4 and outlet nozzle 5. Second, nitrogen gas is continuously introduced into the cooling inner tube 6 through the air pipe connector 10. Then, the steel wire 101 to be cooled is inserted through the ceramic wire nozzle 78 in the inlet end cover 7, then through the tapered sleeve 9 in the cooling inner tube 6 and out through the ceramic wire nozzle 78 in the outlet end cover 8. The steel wire 101 is continuously pulled through the cooling inner tube 6. During the passage of the steel wire 101, the circulating cooling water continuously cools the entire device and the steel wire 101. At the same time, the introduced nitrogen gas directly cools the steel wire 101, and the introduced nitrogen gas can effectively prevent oxygen in the air from contacting the steel wire 101.

[0042] In addition, the steel wire cooling device 100 can be a unit, and several units can be connected and used according to actual use.

[0043] The steel wire cooling device of this utility model has a simple structure and is easy to thread. It can not only quickly cool the steel wire after high-temperature processing, but also prevent the cooled steel wire from being oxidized and decarburized, which greatly improves the cooling efficiency and the performance and quality of the steel wire.

[0044] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
