Description

Technical Field

[0001] The utility model belongs to the field of continuous casting machines and relates to a sector segment for online sewage discharge. Background Art

[0002] Continuous steel casting is the process of continuously pouring hot molten steel into ingots with a specific cross-sectional shape and size. The equipment that completes this process is called a continuous casting equipment set, commonly referred to as a continuous casting machine.

[0003] The segments of the continuous casting machine that deflect the cast strand from vertical to horizontal are called segments. From top to bottom, these segments include segment 1, segment 2, segment 3, and segment 4. To prevent high-temperature damage to the rollers in segments 2, 3, and 4 caused by the cast strand, cooling water lines are installed in these segments.

[0004] Cooling water discharge ports are provided at the bottom of the second, third and fourth sector segments. As they are used, the cooling water pipelines may be clogged with internal impurities due to oxidation and other factors, affecting the normal cooling of the second, third and fourth sector segments. In severe cases, this may cause the normal operation of the internal rollers.

[0005] In current technology, cleaning the cooling water lines—that is, draining the liquid from the cooling water lines through the cooling water drain port—requires shutting down the machine and removing segments 2, 3, and 4. This results in inconvenient cleaning of the cooling water lines, complicated operations, and lengthy maintenance. Utility Model Content

[0006] In order to overcome the defects in the above-mentioned related technologies, the utility model proposes a sector segment with online sewage discharge, which enables the sector segment to realize online cleaning and sewage discharge of the cooling water pipeline during operation.

[0007] To achieve the above technical objectives, the present invention provides a fan-shaped segment with online sewage discharge. The fan-shaped segment with online sewage discharge includes: fan-shaped segment two, fan-shaped segment three, fan-shaped segment four, and a sewage pipe. The lower end of the fan-shaped segment two is provided with a first cooling water sewage outlet. The fan-shaped segment three is arranged below the fan-shaped segment two, and the lower end of the fan-shaped segment three is provided with a second cooling water sewage outlet. The fan-shaped segment four is arranged below the fan-shaped segment three, and the lower end of the fan-shaped segment four is provided with a third cooling water sewage outlet. A sewage pipe is provided at least below the third cooling water sewage outlet. The sewage pipe is a horizontally arranged pipeline, and the sewage pipe is connected to the first cooling water sewage outlet, the second cooling water sewage outlet, and the third cooling water sewage outlet. The sewage pipe is offset from the outlet of the fan-shaped segment four, so that the ingot passing through the outlet of the fan-shaped segment four enters the horizontal section.

[0008] Preferably, the plurality of sector segments are arranged in sequence, and the sewage pipe is provided below the third cooling water sewage outlets of the plurality of sector segments.

[0009] Preferably, a valve is further provided on one end of the sewage pipe extending to the outside of the sector segment, and the valve is configured to control the connection or cutoff of the sewage pipe with the outside world.

[0010] Preferably, the drain pipes include a first drain pipe, a second drain pipe, and a third drain pipe. The first drain pipe is disposed horizontally below the first cooling water drain outlet and is connected to the first drain pipe. The second drain pipe is disposed horizontally below the second cooling water drain outlet and is connected to the second drain pipe. The third drain pipe is disposed horizontally below the third cooling water drain outlet and is connected to the third drain pipe.

[0011] Preferably, the first cooling water drain outlet, the second cooling water drain outlet and the third cooling water drain outlet are connected to the corresponding drain pipes through a high-temperature resistant metal hose.

[0012] Preferably, the first sewage pipe is arranged between the second sector segment and the third sector segment, and the first sewage pipe is offset from the outlet of the second sector segment, so that the ingot passing through the outlet of the second sector segment enters the third sector segment.

[0013] Preferably, the first sewage drain pipe is located below the casting billet.

[0014] Preferably, the second sewage pipe is arranged between the sector three and the sector four, and the second sewage pipe is offset from the outlet of the sector three, so that the ingot passing through the outlet of the sector three enters the sector four.

[0015] Preferably, the second sewage drain pipe is located below the cast billet.

[0016] Preferably, the third sewage drain pipe is located below the cast billet.

[0017] The beneficial effects of the present invention are:

[0018] The utility model adopts a sewage pipe, which is connected to the cooling water sewage outlet of the corresponding fan-shaped segment, so that the cooling water pipeline inside the fan-shaped segment can be internally cleaned and sewage can be discharged when the fan-shaped segment is in operation, thereby reducing the difficulty of cleaning the cooling water pipeline, increasing the number of cleaning times of the cooling water pipeline, and avoiding the occurrence of blockage of the cooling water pipeline.

[0028] like Figures 1 to 4 As shown, some embodiments of the present invention provide a fan-shaped segment with online sewage discharge. The fan-shaped segment with online sewage discharge includes: fan-shaped segment 2 1, fan-shaped segment 3 2, fan-shaped segment 4 3 and a sewage pipe 4. The lower end of the fan-shaped segment 2 1 is provided with a first cooling water sewage outlet 11. The fan-shaped segment 3 2 is provided below the fan-shaped segment 2 1, and the lower end of the fan-shaped segment 3 2 is provided with a second cooling water sewage outlet 21. The fan-shaped segment 4 3 is provided below the fan-shaped segment 3 2, and the lower end of the fan-shaped segment 4 3 is provided with a third cooling water sewage outlet 31. A drain pipe 4 is provided at least below the third cooling water drain outlet 31. The drain pipe 4 is a horizontally arranged pipeline. The drain pipe 4 is connected with the first cooling water drain outlet 11, the second cooling water drain outlet 21 and the third cooling water drain outlet 31. The drain pipe 4 is offset from the outlet of the fourth sector 3 so that the ingot passing through the outlet of the fourth sector 3 enters the horizontal section.

[0029] In some examples, such as Figure 1 and Figure 2 As shown, the drain pipe 4 can be a steel pipe with an inner diameter of 30-50 mm. A first drain pipe 41 is set between the second sector 1 and the third sector 2 below the first cooling water drain outlet 11, a second drain pipe 42 is set between the third sector 2 and the fourth sector 3 below the second cooling water drain outlet 21, and a third drain pipe 43 is set below the third cooling water drain outlet 31. The first drain pipe 41 is connected to the first cooling water drain outlet 11, the second drain pipe 42 is connected to the second cooling water drain outlet 21, and the third drain pipe 43 is connected to the third cooling water drain outlet 31. Figure 5 As shown, four cooling water drain outlets are provided below the sector segment 2 1, the sector segment 3 2, and the sector segment 4 3, that is, in each continuous casting machine, the first drain pipe 41 is connected to the two first cooling water drain outlets 11, the second drain pipe 42 is connected to the two second cooling water drain outlets 21, and the third drain pipe 43 is connected to the two third cooling water drain outlets 31.

[0030] Or, in other examples, Figure 3 and Figure 4 As shown, only one drain pipe 4 is provided below the third cooling water drain outlet 31 , and the first cooling water drain outlet 11 , the second cooling water drain outlet 21 and the third cooling water drain outlet 31 are all connected to the drain pipe 4 .

[0031] It is understood that cooling water inlets are also provided on segment 2 1 , segment 3 2 , and segment 4 3 . These cooling water inlets can be connected to a cooling water source. For example, water inlet pipes can be provided, and the water inlet pipes can be connected to the corresponding cooling water inlets via metal hoses.

[0032] In some embodiments, the plurality of sector segments are arranged in sequence, and the drain pipe 4 is disposed below the third cooling water drain outlets 31 of the plurality of sector segments.

[0033] For example, for steel rolling enterprises, multiple continuous casting machine bodies are generally arranged in parallel, that is, multiple sector segments are arranged in parallel in sequence. Based on the above example, the first sewage pipe 41, the second sewage pipe 42 and the third sewage pipe 43 cross multiple sector segments, and the first sewage pipe 41 on each sector is connected to the first sewage pipe 41, the second sewage pipe 42 is connected to the second sewage pipe 42, and the third sewage pipe 43 is connected to the third sewage pipe 43.

[0034] Alternatively, one sewage pipe 4 runs through multiple sectors and is connected to all cooling water sewage outlets of the sectors.

[0035] In some embodiments, a valve 5 is further provided on one end of the sewage pipe 4 extending to the outside of the sector, and the valve 5 is configured to control the connection or cutoff of the sewage pipe 4 with the outside.

[0036] For example, one end of drain pipe 4 extends outside the fan-shaped segment, for example, within the range of 0.5m to 1.0m of the fan-shaped segment. A valve is installed to control the opening or closing of drain pipe 4. Specifically, when the valve is open, the cooling water outlet discharges cooling water through drain pipe 4, simultaneously removing impurities from the cooling water pipeline. Cooling water can also be continuously injected into the cooling water pipeline. When the valve is closed, the cooling water in the cooling water pipeline circulates internally to achieve normal cooling.

[0037] In some embodiments, the drain pipe 4 includes a first drain pipe 41, a second drain pipe 42, and a third drain pipe 43. The first drain pipe 41 is horizontally disposed below the first cooling water drain outlet 11, and the first cooling water drain outlet 11 is connected to the first drain pipe 41. The second drain pipe 42 is horizontally disposed below the second cooling water drain outlet 21, and the second cooling water drain outlet 21 is connected to the second drain pipe 42. The third drain pipe 43 is horizontally disposed below the third cooling water drain outlet 31, and the third cooling water drain outlet 31 is connected to the third drain pipe 43.

[0038] The first cooling water drain outlet 11 , the second cooling water drain outlet 21 and the third cooling water drain outlet 31 are connected to the corresponding drain pipes 4 through high-temperature resistant metal hoses.

[0039] The first sewage pipe 41 is arranged between the sector section 2 1 and the sector section 3 2 , and the first sewage pipe 41 is offset from the outlet of the sector section 2 1 , so that the ingot passing through the outlet of the sector section 2 1 enters the sector section 3 2 .

[0040] The first sewage pipe 41 is located below the casting billet.

[0041] The second sewage pipe 42 is arranged between the sector three section 2 and the sector four section 3, and the second sewage pipe 42 is offset from the outlet of the sector three section 2, so that the casting billet passing through the outlet of the sector three section 2 enters the sector four section 3.

[0042] The second sewage pipe 42 is located below the casting strand.

[0043] The third sewage pipe 43 is located below the casting billet.

[0044] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0045] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
