Description

Technical Field

[0001] This utility model relates to the field of finished product trough water pipe device, and in particular to a three-section finished product trough water pipe device and rolling mill. Background Technology

[0002] The typical processes of a bar production line include: billet acceptance, heating, rolling, multiple-length shearing, cooling, shearing, inspection, packaging, measurement, and warehousing. Bar slitting rolling is a special rolling method where a single billet is processed through special passes on rolls to form parallel rolled sections. These sections are then divided into two or more sections with equal cross-sectional areas using slitting guides, and further processed into multiple finished bars of the same size. The slitting bars require guide grooves for guidance.

[0003] An existing steel beam cold rolling mill, patent publication number CN217665418U, includes a spray mechanism for cooling the rolls. The spray mechanism includes two water collection pipes, one end of which is connected to an external cold water pipe. The water collection pipes are formed by several telescopic pipes connected together. The side of the telescopic pipe facing its corresponding roll is connected to a nozzle. The position of each nozzle relative to the water collection pipe can be adjusted by adjusting the length of each telescopic pipe. Figure 3 shows that the nozzles on the water collection pipes are arranged side by side in the horizontal direction, and each telescopic pipe has one nozzle.

[0004] As mentioned above, in existing finished product trough water pipe devices, the nozzles are usually arranged side by side and evenly distributed in the horizontal direction. However, in the later stages of finished product trough use, due to temperature drop and material shape issues, the wear of the two side troughs is greater than that of the middle trough, which can easily lead to uneven negative difference between the two side steels and the middle steel, and has a great impact on negative difference control. Utility Model Content

[0005] This utility model provides a three-section finished product trough water pipe device and rolling mill to solve the technical problem in the prior art that easily leads to uneven negative difference between the two sides of the steel and the middle steel.

[0006] To solve the above problems, the present invention provides a three-section finished product casting trough water pipe device and rolling mill, which adopts the following technical solution:

[0007] A three-section finished trough water pipe device includes a water pipe body with an inlet and an outlet. The outlet includes at least two groups, namely a middle outlet group and a side outlet group. The vertical center axis of the middle outlet group coincides with the vertical center axis of the water pipe body. The side outlet group is offset to one side of the vertical center axis of the water pipe body. The number of outlets in the side outlet group is greater than the number of outlets in the middle outlet group.

[0008] Furthermore, a quick connector is provided on the water pipe body at the water inlet, and the water pipe body is connected to the water inlet pipe through the quick connector.

[0009] Furthermore, the water pipe body is a circular pipe structure, and the water outlet is designed as a square structure.

[0010] Furthermore, the side outlet group includes two groups, which are located on both sides of the middle outlet group and are symmetrically distributed about the vertical central axis of the water pipe body.

[0011] Furthermore, the water pipe body is fixedly connected to a support for bearing the weight of the pipe channel and the medium.

[0012] A rolling mill includes a rolling mill body, and also includes the aforementioned three-section finished product gating water pipe device and rolling mill.

[0013] A three-section finished trough water pipe device includes a water pipe body with an inlet and an outlet. The outlet includes at least two groups, namely a middle outlet group and a side outlet group. The vertical center axis of the middle outlet group coincides with the vertical center axis of the water pipe body. The side outlet group is offset to one side of the vertical center axis of the water pipe body. The number of outlets in the side outlet group is greater than the number of outlets in the middle outlet group.

[0014] Furthermore, a quick connector is provided on the water pipe body at the water inlet, and the water pipe body is connected to the water inlet pipe through the quick connector.

[0015] Furthermore, the water pipe body is a circular pipe structure, and the water outlet is designed as a square structure.

[0017] Furthermore, the water pipe body is fixedly connected to a support for bearing the weight of the pipe channel and the medium.

[0018] Furthermore, the mill body includes a roll, a guide located on one side of the roll, a water pipe body inserted into the guide via a support, a groove on the roll, and a water outlet corresponding to the groove.

[0019] Furthermore, the water pipe body is parallel to the rolling mill roll, and in the horizontal direction, the water pipe body is perpendicular to the rolling mill groove.

[0020] The beneficial effects of the three-section finished product casting groove water pipe device and rolling mill provided by this utility model are: ensuring uniform cooling of the middle rolling groove and enhancing the cooling effect of the side rolling groove, effectively compensating for the increased cooling demand of the side rolling groove due to wear, and stabilizing the negative tolerance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] The present invention provides a three-section precast trough water pipe device, such as... Figures 1 to 2 As shown, the water pipe body 1 is provided with an inlet 11 and an outlet 12. The outlet 12 includes at least two sets, namely a middle outlet group 121 and a side outlet group 122.

[0032] In this embodiment, the water pipe body 1 is the core part of the cooling system, responsible for transporting cooling water. The inlet 11 is used to introduce cooling water into the water pipe body 1, while the outlet 12 is used to discharge cooling water into the rolling trough 311 (described below). In this embodiment, the outlet 12 is divided into a middle outlet group 121 and a side outlet group 122, which helps to target different areas of the rolling trough 311 for cooling.

[0033] like Figure 1 As shown, in this embodiment, the vertical center axis of the intermediate outlet group 121 coincides with the vertical center axis of the water pipe body 1, and the side outlet group 122 is offset to one side about the vertical center axis of the water pipe body 1. The number of outlets 12 in the side outlet group 122 is greater than the number of outlets 12 in the intermediate outlet group 121, ensuring that the intermediate groove 311 is cooled evenly and enhancing the cooling effect on the side groove 311, which can effectively compensate for the increased cooling demand of the side groove 311 due to wear.

[0034] In this embodiment, a quick connector is provided on the water pipe body 1 at the water inlet 11. The water pipe body 1 is connected to the water inlet pipe through the quick connector. The quick connector allows for quick and easy connection or disconnection of the water inlet pipe and the water pipe body 1, which can effectively simplify the installation, disassembly and maintenance process and reduce downtime.

[0035] In this embodiment, the water pipe body 1 is a circular pipe structure, which has advantages in fluid dynamics, can reduce fluid resistance, improve the flow efficiency of cooling water, and is easy to manufacture and process, and has high strength and stability, and can withstand certain internal pressure and external force.

[0036] In this embodiment, the outlet 12 is configured as a square structure. The square outlet 12 can provide a more uniform water flow distribution, especially when it is necessary to cover a large area or a groove 311 of a specific shape.

[0037] In other embodiments, a flow control valve may be introduced into the device to independently adjust the cooling water flow of the middle and side outlets 12, so as to flexibly adjust the cooling intensity of each set of outlets 12 according to the actual wear and production needs.

[0038] like Figure 1As shown, in this embodiment, the side outlet group 122 includes two groups, which are located on both sides of the middle outlet group 121. The two groups of side outlet groups 122 are symmetrically distributed about the vertical central axis of the water pipe body 1, ensuring that the cooling water can evenly cover both sides of the rolling groove 311, avoiding wear differences in the rolling groove 311 caused by uneven cooling, and also helping to balance the distribution of cooling water on the rolling groove 311, reducing the possibility of local overheating or undercooling. This embodiment is applicable to three-section finished product casting grooves. In other embodiments, the side outlet group 122 and the middle outlet group 121 can be set as one or more groups, adjusted according to the actual working environment. It should be noted that in the case of multi-section finished product casting grooves, the number of outlets 12 in the side outlet group 122 decreases stepwise along the side towards the middle outlet group 121.

[0039] In this embodiment, the water pipe body 1 is fixedly connected to a support member 2 for supporting the weight of the pipe channel and the medium. In this embodiment, the support member 2 is welded to the water pipe body 1. The support member 2 includes two sets, which are located at both ends of the water pipe body 1 respectively. The support member 2 is a hollow square tube structure.

[0040] like Figure 2 As shown, this utility model also provides a rolling mill, including a rolling mill body 3, and also includes the above-described three-section finished product casting trough water pipe device.

[0041] In this embodiment, the mill body 3 includes a roll 31 and a guide 32 located on one side of the roll 31. The water pipe body 1 is inserted into the guide 32 through the support member 2. The roll 31 is provided with a groove 311 and the water outlet 12 corresponds to the groove 311.

[0042] In this embodiment, the middle outlet group 121 and the two side outlet groups 122 correspond one-to-one with the rolling groove 311 to provide an effective cooling effect.

[0043] In this embodiment, the water pipe body 1 and the roller 31 are parallel to each other, and in the horizontal direction, the water pipe body 1 and the groove 311 are perpendicular to each other.

[0044] It should be noted that rolling mills are existing technology, and those skilled in the art should be clear about their structure, principles, and usage methods, etc., which will not be described in detail here.

[0045] The present invention provides a three-section finished product trough water pipe device and rolling mill. The design of the water pipe device enables the water outlet 12 to accurately correspond to the position of the trough 311, ensuring that the cooling water can be directly sprayed onto the trough 311, thereby achieving efficient cooling. By reasonably arranging the water outlet 12, the negative difference is stabilized, which can effectively avoid the situation where the negative difference between the two sides of the steel is uneven relative to the middle steel.

[0046] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0047] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
