Description

[0001] This application relates to the field of iron and steel metallurgy technology, and in particular to a segmented fan-shaped section machine cooling piping water cooling fixture. Background Technology

[0002] In steel manufacturing, the sector section is a core component of the continuous casting machine. It is located after the support guide section and before the cutting roller table. The main function of the sector section is to pull and straighten the cast slab to reduce the bulging strain and straightening strain generated at the two boundaries of the slab shell under the static pressure of molten steel.

[0003] The fan-shaped section mainly consists of upper and lower frames supporting the continuous casting rollers, cooling devices, spraying devices, lubrication devices, etc. The rollers are in direct contact with the steel billet, and the surface temperature of the steel billet is extremely high. In order to extend the service life of the rollers, the rollers and bearings need to be water-cooled to prevent the rollers and bearings from seizing due to low cooling effect, which would cause scratches on the surface of the cast billet.

During the upgrade, it is necessary to increase the amount of cooling water without reducing the cooling effect of the original production line, and the new rollers need to be able to cooperate with the original cooling inlet / outlet water channels to move the casting.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Figures 1 to 5 show the structural diagrams of a segmented fan-shaped section cooling pipe water-cooling fixture provided in an embodiment of this application. As shown, the fixture includes a frame 1, a roller assembly, and a main water channel 2, wherein the main water channel 2 is installed inside the frame 1. The roller assembly is placed horizontally, and multiple seat block assemblies are spaced apart along the circumference of the roller assembly in the axial direction. The roller assembly is connected to the frame 1 through the multiple seat block assemblies.

[0028] The lower part of the multiple seat block assemblies is provided with water receiving plates 5, and the seat block assemblies are connected to the corresponding roller assemblies through the water receiving plates 5. The upper part of the multiple seat block assemblies is fixedly connected to the frame 1.

[0029] The roller assembly has a segmented structure, including a first roller 31, a second roller 32, a third roller 33, and a fourth roller 34. Each roller has an internal water channel for cooling water to be introduced, thereby cooling the roller.

[0030] It should be noted that the internal water channel of the roller assembly is not limited to the style shown in Figure 2, but may have other styles. In this embodiment, the internal water channel of the roller is only illustrated based on Figure 2, and is not limited to this style.

[0031] As shown in Figure 1, in the roller assembly, one end of the first roller 31 is provided with a roller rotary joint 6, and the other end is connected to one end of the second roller 32 through a bearing seat 7. The other end of the second roller 32 is provided with a roller rotary joint 6.

[0032] One end of the third roller 33 is provided with a roller rotary joint 6, and the other end is connected to one end of the fourth roller 34 through a bearing seat 7. The other end of the fourth roller 34 is provided with a roller rotary joint 6.

[0033] The seat block assembly includes a joint seat block 41 and a bearing seat block 42. The lower end of the joint seat block 41 is connected to the roller rotary joint 6, and the upper end is fixedly connected to the frame 1. The lower end of the bearing seat block 42 is connected to the bearing seat 7, and the upper end is fixedly connected to the frame 1.

[0034] In this embodiment of the application, the segmented fan-shaped section machine cooling piping water cooling fixture also includes a roller cooling water circuit assembly and a bearing cooling water assembly.

[0035] The roller cooling water circuit assembly includes a first water circuit assembly and a second water circuit assembly.

[0036] Specifically, one end of the first water channel assembly is connected to the main water channel 2, and the other end is connected to the internal water channel of the first roller 31 and the internal water channel of the second roller 32. The first water channel assembly is used to cool the first roller 31 and the second roller 32.

[0037] One end of the second water channel assembly is connected to the main water channel 2, and the other end is connected to the internal water channels of the third roller 33 and the fourth roller 34. The second water channel assembly is used to cool the third roller 33 and the fourth roller 34.

[0038] One end of the bearing 73 cooling water circuit assembly is connected to the main water circuit 2, and the other end is connected to the bearing housing 7 through the internal water circuit of the bearing housing 7.

[0039] This application embodiment solves the technical problem of traditional sector sections where it is difficult to replace rollers of different structures without changing the original cooling water inlet / outlet structure, by adding two sets of cooling water components connected to the original cooling water inlet / outlet of the sector section. This achieves the technical effect of reducing the cooling cost of rollers and bearings, increasing the service life of the rollers in the sector section, and enabling the sector section to cool each section of rollers.

[0040] Specifically, each seat block assembly has a seat block water channel inside, and each roller rotary joint 6 has a joint water channel inside.

[0041] Meanwhile, the roller rotary joint 6 connected to the second roller 32 is set opposite to the roller rotary joint 6 connected to the third roller 33, and the back is fixed. The water channels inside the roller rotary joints 6 of the two rollers are not interconnected.

[0042] In this embodiment, the first water circuit component includes a first inlet pipe 81, a first flexible hose 82, and a first return bend 83.

[0043] One end of the first water inlet pipe 81 is connected to the main water passage 2, and the other end is connected to the joint water passage of the roller rotary joint 6 through the seat block water passage. The other end of the joint water passage is connected to the internal water passage of the second roller 32.

[0044] The internal water passage of the second roller 32 is connected to the internal water passage of the first roller 31. The internal water passage of the first roller 31 is connected to one end of the first hose 82 through the connector water passage. The other end of the first hose 82 is connected to the main water passage 2 through the first loop bend 83.

[0045] The second water circuit assembly includes a second inlet pipe 91, a second hose 92, and a second return bend 93.

[0046] One end of the second water inlet pipe 91 is connected to the main water channel 2, and the other end of the second water inlet pipe 91 is connected to the internal water channel of the third roller 33 through the seat block water channel and the connector water channel. The internal water channel of the third roller 33 is connected to the internal water channel of the fourth roller 34, and the internal water channel of the fourth roller 34 is connected to one end of the second flexible hose 92. The other end of the second flexible hose 92 is connected to the main water channel 2 through the second circuit bend pipe 93.

[0047] As shown in Figures 3 to 5, in the embodiments of this application, the bearing cooling water circuit assembly includes a bearing cooling water inlet pipe 71, a bearing cooling water outlet pipe 72, and multiple internal bearing water circuits.

[0048] One end of the bearing cooling water inlet pipe 71 is connected to the main water passage 2, and the other end of the bearing cooling water inlet pipe 71 is connected to the water inlet of the internal water passage of the bearing in multiple bearing housings 7. After the internal water passage of the bearing wraps around the circumference of the bearing 73, the water outlet of the internal water passage of the bearing is connected to one end of the bearing cooling water outlet pipe 72, and the other end of the bearing cooling water outlet pipe 72 is connected to the main water passage 2.

[0049] The bearing cooling water circuit assembly is used in conjunction with the main water circuit 2 to cool the bearing 73.

[0050] For example, the internal water channels of the roller are separated from the bearing cooling water channels.

[0051] Meanwhile, the water receiving plate 5 mentioned in the embodiments of this application is a detachable structure that can be disassembled according to user needs.

[0052] Figures 6 to 8 show the structural diagrams of a traditional sector-shaped section water-cooled fixture. In the traditional sector-shaped section machine cooling piping water-cooled fixture, the cooling process for the rollers is as follows:

[0053] Cooling water enters the leftmost seat block (equivalent to the connector seat block 41 in this application) connected to the roller assembly from the roller cooling inlet in the main water channel 2. Then, it directly enters the internal water channel of the roller rotary joint 6 through the internal water channel of the leftmost seat block. The roller rotary joint 6 is directly connected to the roller assembly. The internal water channel of the roller rotary joint 6 is connected to the internal water channel of the roller assembly. The other end of the internal water channel of the roller assembly is connected to the rightmost roller rotary joint 6. The rightmost roller rotary joint 6 is connected to the roller cooling water return end through the rightmost seat block.

[0054] During the cooling process of bearing 73, bearing cooling water enters the left end block of frame 1 (equivalent to bearing block 42 in this embodiment) through the main water channel and bearing cooling water inlet. It then enters the roller bearing seat 7 through the water channel inside the block and the water receiving plate 5. Finally, it circulates through the water channel inside the roller to the right end block (equivalent to bearing block 42 in this embodiment) and returns to the bearing cooling return end of the main water channel, thereby achieving the purpose of cooling bearing 73.

[0055] Traditional fan-shaped section machine cooling piping water cooling fixtures can only be used in the cooling water circuit of the old structure rollers. When replacing the rollers with the new structure, the cooling water circuit of the entire frame 1 needs to be replaced, which is too costly.

[0056] Therefore, this application employs a fan-shaped section cooling piping water-cooling fixture applicable to both segmented and non-segmented rollers.

[0057] As shown in Figure 2, in this embodiment, the flow path of the cooling water on the left is as follows:

[0058] The cooling water in the main water channel 2 is guided through the first water inlet pipe 81 to the water channel of the leftmost connector block 41 below the frame 1. Since the water channel of the leftmost connector block 41 is connected to the water channel of the middle connector block 41 near the second roller 32, the cooling water flows from the water channel of the leftmost connector block 41 into the water channel of the middle connector block 41 connected to the second roller 32.

[0059] The connector seat block 41, located near the second roller 32, is connected to the internal water channel of the roller rotary joint 6. The roller rotary joint 6 is also connected to the internal water channel of the second roller 32. Therefore, cooling water flows from the internal water channel of the connector seat block 41 through the internal water channel of the roller rotary joint 6 and into the internal water channel of the second roller 32, completing the cooling process for the second roller 32.

[0060] Then, cooling water flows from the internal water passage of the second roller 32 into the internal water passage of the first roller 31. The other end of the internal water passage of the first roller 31 is connected to one end of the joint water passage of the other roller rotary joint 6. The cooling water flows through the internal water passage of the first roller 31 into the joint water passage of the roller rotary joint 6, completing the cooling process of the first roller 31.

[0061] Afterwards, the cooling water flows back into the main water channel 2 through the first hose 82 and the first loop bend 83, completing the cooling process for the left end roller assembly.

[0062] Similar to the cooling process of the left roller assembly, the cooling methods for the third roller 33 and the fourth roller 34 in the right roller assembly are the same, and will not be described in detail here.

[0063] The cooling method for bearing 73 includes: bearing cooling water enters bearing cooling inlet pipe 71 from the main water channel. Bearing cooling inlet pipe 71 is connected to the inlet of the internal water channel of the bearing through the seat block water channel of bearing seat block 42. Therefore, bearing cooling water enters the internal water channel of the bearing. Simultaneously, under pressure, the bearing cooling water flows around the circumference of bearing 73 once and then flows out from bearing cooling outlet pipe 72, passing through the seat block water channel of bearing seat block 42 and flowing into the main water channel, thus completing the cooling of bearing 73 and bearing seat 7. In traditional fan-shaped section machine cooling piping water cooling fixtures, the positions of the main water channel inlet and return of the fan-shaped section are fixed. This embodiment adds a first water channel component and a second water channel component, combining a new structure to complete the internal water circulation during roller assembly. This allows for cooling of the segmented rollers and bearing seat without replacing the frame when the roller assembly form changes.

[0064] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
