[0002] The crystallizer copper tube is usually used in the crystallizer of the continuous casting production line. It is a square or rectangular copper tube bent to one side. The outer wall of the crystallizer copper tube is provided with a jacket, and the wall is provided with a circulation channel to cool the crystallizer copper tube and the high-temperature copper liquid passing through the crystallizer copper tube. The crystallizer copper tube is an important component connecting the continuous casting machine and the heat treatment equipment. The performance and quality of the crystallizer copper tube will directly affect the quality of the surface of the ingot and the uniformity of the internal structure of the ingot, especially the cooling effect of the crystallizer copper tube, which directly determines the quality of the molten steel passing through.

[0004] Therefore, it is necessary for those skilled in the art to provide a crystallizer with an adjustable flow channel, to control the number of flow channels used in the copper tube of the crystallizer, and to ensure the stability of use and the processing effect. Utility Model Content

DETAILED DESCRIPTION

[0023] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0024] See also Figure 1 , Figure 2 , Figure 3 The utility model provides a crystallizer with adjustable flow channels, which is used to adjust the number of flow channels 11 on the crystallizer copper tube 10. The flow channels 11 are provided with a plurality of channels and are evenly arranged in the wall of the crystallizer copper tube 10. Both ends of the flow channels 11 penetrate the wall of the crystallizer copper tube 10. The crystallizer with adjustable flow channels includes an inner fixed ring 21 and an outer adjustable ring 22. The inner fixed ring 21 is sleeved on the crystallizer copper tube 10, and the outer adjustable ring 22 is slidably sleeved on the inner fixed ring 21.

[0025] It can be understood that the crystallizer copper tube 10 is provided with a water jacket (not shown in the figure), the water jacket is connected to the outside of the crystallizer copper tube 10, the circulation channel 11 is located between the water jacket and the crystallizer copper tube 10, and cooling water is passed through the circulation channel 11 to achieve cooling of the crystallizer copper tube 10.

[0026] Further, the inner fixing ring 21 is provided with a first communication gap 23, and the outer adjusting ring 22 is provided with a second communication gap 24, the first communication gap 23 corresponds to and is connected to the circulation channel 11, and the second communication gap 24 corresponds to and is connected to the first communication gap 23. The number of the second communication gaps 24 is less than the number of the first communication gaps 23.

[0027] When in use, the outer adjustment ring 22 is sleeved on the inner fixed ring 21 to change the number of the first connecting notches 23 on the inner fixed ring 21, thereby changing the number of the circulation channels 11 on the crystallizer copper tube 10, thereby achieving cooling control. For processing techniques that require a higher cooling temperature, the utility model indirectly reduces the number of circulation channels 11 on the crystallizer copper tube 10 by adding an inner fixed ring 21 and an outer adjustment ring 22 to the crystallizer copper tube 10, thereby reducing the cooling effect of the crystallizer copper tube 10, thereby achieving an increase in cooling temperature; for processing techniques that require a lower cooling temperature, the outer adjustment ring 22 is moved to indirectly increase the number of circulation channels 11 on the crystallizer copper tube 10, thereby improving the cooling effect of the crystallizer copper tube 10, thereby achieving a lower cooling temperature.

[0028] For further information, see Figure 4 , Figure 5 The inner fixing ring 21 is a square frame structure, and the first connecting notches 23 are provided in plurality and penetrate the wall of the inner fixing ring 21, and one first connecting notch 23 corresponds to and connects to one flow channel 11. In this embodiment, the profile of the inner fixing ring 21 is consistent with the profile of the crystallizer copper tube 10, and the inner fixing ring 21 is detachably connected to the crystallizer copper tube 10.

[0029] Furthermore, the outer adjustment ring 22 is a square frame structure, and the second communication gap 24 is provided with a plurality of gaps and penetrates the wall of the outer adjustment ring 22, and one second communication gap 24 corresponds to and communicates with one first communication gap 23. In this embodiment, the second communication gap 24 has the same profile as the first communication gap 23, and the second communication gap 24 is aligned with the first communication gap 23. This ensures the stability of the coolant circulation.

[0030] The outer adjusting ring 22 is detachably connected to the inner fixing ring 21. The outer adjusting ring 22 and the inner fixing ring 21 are matched and connected, and the inner wall contour of the outer adjusting ring 22 is consistent with the outer wall contour of the inner fixing ring 21.

[0031] Furthermore, a third connecting gap 28 is provided on the inner wall of the outer adjustment ring 22 between two adjacent second connecting gaps 24 . The third connecting gap 28 is opened inward from the inner wall of the outer adjustment ring 22 . One third connecting gap 28 corresponds to and connects to one first connecting gap 23 . At the same time, the third connecting gap 28 connects to the outside of the outer adjustment ring 22 .

[0032] The outer adjustment ring 22 is provided with a plurality of blocking blocks 29, one blocking block 29 is fitted and connected in the third communication notch 28, and a portion of the blocking block 29 is fitted and connected in the circulation channel 11 and abuts against the inner wall of the circulation channel 11. Preferably, the blocking block 29 is made of rubber.

[0033] During use, after the outer adjustment ring 22 is sleeved on the inner fixed ring 21, the third connecting gap 28 and the second connecting gap 24 both correspond to and are connected with the first connecting gap 23, and the coolant flows from the third connecting gap 28 and the second connecting gap 24 into the first connecting gap 23, and finally enters the circulation channel 11, thereby cooling the crystallizer copper tube 10. The utility model connects the blocking block 29 to the third connecting gap 28, so that part of the opening of the circulation channel 11 is blocked, thereby reducing the circulation of the coolant and indirectly blocking the circulation channel 11. By changing the number of blocking blocks 29 made of rubber, the cooling effect of the crystallizer copper tube 10 is controlled, thereby improving the quality of the surface of the ingot in the crystallizer copper tube 10 and the uniformity of the internal structure of the ingot, thereby ensuring product quality.

[0034] In this embodiment, the inner fixing ring 21 is provided with a plurality of through holes 25, and the through holes 25 are threadedly connected with locking pieces 27, which penetrate the inner fixing piece 21 and abut against the outer wall of the crystallizer copper tube 10. In this way, the inner fixing ring 21 is fixedly connected to the crystallizer copper tube 10; the outer adjustment ring 22 is slidably sleeved on the inner fixing ring 21, and the bottom surface of the outer adjustment ring 22 can overlap the locking piece 27. When in use, the outer adjustment ring 22 is moved, and the blocking block 29 is separated from the inner wall of the circulation channel 11, so that the circulation channel 11 and the outside of the outer adjustment ring 22 are connected to each other, and the outer adjustment ring 22 is overlapped on the locking piece 27 to prevent it from falling back and blocking the circulation channel 11, while reducing disassembly, improving the stability and convenience of use, and realizing the blocking control between some circulation channels 11.

[0035] Preferably, the locking member 27 includes but is not limited to a hexagon socket bolt.

[0036] The specific operation mode of the utility model is as follows: for a processing technology that requires a higher cooling temperature, the outer adjustment ring 22 is connected to the outside of the inner fixing member 21, and the blocking block 29 is connected to the inner wall of the circulation channel 11 and blocks the circulation channel 11, which indirectly reduces the circulation amount of the circulation channel 11 on the crystallizer copper tube 10, thereby reducing the cooling effect of the crystallizer copper tube 10, thereby achieving an increase in the cooling temperature. For a processing technology that requires a lower cooling temperature, by moving the outer adjustment ring 22, the blocking block 29 is separated from the inner wall of the circulation channel 11, so that the circulation channel 11 and the outside of the outer adjustment ring 22 are interconnected, indirectly increasing the circulation amount of the circulation channel 11 on the crystallizer copper tube 10, thereby improving the cooling effect of the crystallizer copper tube 10, thereby achieving a lower cooling temperature.

[0037] The utility model realizes control of the flow quantity of the flow channel 11 on the crystallizer copper tube 10 by adding an inner fixing ring 21 and an outer adjusting ring 22 to the crystallizer copper tube 10, thereby increasing or decreasing the cooling temperature of the crystallizer copper tube 10; the control of the temperature of the crystallizer copper tube 10 can effectively improve the surface quality of the ingot in the crystallizer copper tube 10 and the uniformity of the internal structure of the ingot, thereby ensuring the product quality.
