Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, and more particularly to a cooling device for a water-cooled continuous casting stopper rod. Background Art

[0002] The continuous casting stopper mechanism is one of the important flow control components in the continuous casting process. The stopper controls the opening of the tundish water inlet and adjusts the flow of molten steel from the tundish to the crystallizer to maintain the stability of the molten steel level. It is controlled by the continuous casting stopper automatic control system, and the stopper mechanism drives the stopper to move up and down to achieve opening and closing flow control. During production casting, the high temperature generated will affect the normal operation of some equipment inside the continuous casting stopper mechanism. In order to enable the continuous casting stopper mechanism to operate for a long time, the stopper sleeve needs to be cooled to facilitate the flow of molten steel.

[0003] Among them, patent publication number CN221209873U discloses a cooling device for a continuous casting stopper mechanism, which relates to the field of cooling devices. The device comprises a machine body, a main shaft, a crossbeam, and a stopper. The machine body and the crossbeam are hollow structures. The main shaft is disposed within the machine body, extending through the top of the machine body and fixedly connected to the crossbeam. The stopper is fixedly connected to the other end of the crossbeam, and a cooling mechanism is disposed within the crossbeam.

[0004] When this structure is in use, the equipment is cooled from top to bottom through the water-cooling pipe by arranging a sleeve, an air inlet pipe, a water-cooling pipe, an exhaust pipe, an air vent, a cooling hole, and a U-shaped groove, and cold air is introduced from the air inlet pipe so that the cold air dissipates heat from bottom to top to the equipment, and dissipates heat inside and outside the main shaft at the same time. However, the single air cooling and the cooling efficiency through air cooling of this structure are low, and the cooling airflow is not easy to fully contact with the stopper rod, resulting in poor cooling effect. Moreover, when a single stopper rod is used for a long time, its size will become smaller due to the high temperature, which will reduce the flow accuracy when the molten iron is discharged, and the machine needs to be stopped for replacement, which is not convenient when used.

[0010] Technical effects and advantages of the present invention:

[0011] 1. The present invention uses external high-pressure water to be delivered through the first water inlet and the second water inlet. The water delivered through the first water inlet is injected into the connecting pipe through the diverter hole body. The cooling water flow is gathered through the connecting pipe and injected into the stopper sleeve through the bottom of the connecting pipe to first cool the stopper sleeve. The spiral strips, guide holes and reinforcement rings embedded in the stopper sleeve facilitate the cooling water to be delivered in a vortex shape in the connecting pipe and the stopper sleeve, thereby improving the medium delivery efficiency. The used water can be used to cool the casting parts in subsequent processes, saving water resources and reducing costs.

[0012] 2. In the present invention, the cooling water flow injected into the protective cover through the second water inlet hole can be injected into the guide cavity through the frame opening. The water in the guide cavity can be diverted through the water diversion inclined hole and transported to the outside of the stopper sleeve. The water flow transported into the stopper sleeve and the water flow outside the stopper sleeve are combined to achieve the function of wrapping and fully cooling the stopper sleeve.

[0013] 3. When the support inclined seat of the present invention rotates, the water flow in the guide cavity can be ejected in a vortex shape through the water diversion inclined hole, so that the water flow contacts the stopper sleeve and the water can be located between the water guide plate and the protective cover, so that each stopper sleeve and the reinforcing mesh cylinder can be immersed in the cooling water, so that the cooling water can cool the stopper sleeve and then be discharged through the drainage hole;

[0014] 4. In the present invention, when the water guide plate rotates, the original inclined position of the water guide plate is changed, thereby allowing each stopper rod sleeve to be displaced one by one on the reinforced mesh cylinder and compressing the spring. When the water guide plate rotates, the padding ball contacts the water diversion inclined hole, and then the stopper rod sleeve is driven to reset by the padding ball and the elasticity of the spring itself, so that the stopper rod sleeve can generate high-frequency amplitude on the reinforced mesh cylinder, so that impurities remaining on the stopper rod can be removed, which facilitates the rapid cooling of the stopper rod and improves the cooling effect.

[0015] 5. The present invention enables each stopper rod sleeve to be displaced one by one on the reinforcing mesh cylinder, compressing the spring and allowing the remaining stopper rods to be extended one by one through the stopper rod sleeves and connecting tubes, thereby realizing the function of replacing stopper rods without stopping the machine. It can also cool the stopper rods stored in the device, thereby increasing the service life of the stopper rods.

[0016] To sum up, through the corresponding coordinated use of various structures, the cooling water flow is gathered through the connecting pipe and injected into the stopper rod sleeve through the bottom of the connecting pipe to first cool the stopper rod sleeve. The spiral strips, guide holes and reinforcement rings embedded in the stopper rod sleeve facilitate the cooling water to be transported in a vortex shape during transportation in the connecting pipe and the stopper rod sleeve, thereby improving the medium transportation efficiency. The water flow can be injected into the guide cavity through the frame opening, and the water in the guide cavity can be diverted through the water diversion inclined hole and transported to the outside of the stopper rod sleeve. Combined with the water flow transported into the stopper rod sleeve and the water flow outside the stopper rod sleeve, the function of wrapping and comprehensively cooling the stopper rod sleeve is achieved. When the water guide plate rotates, the padding ball contacts the water diversion inclined hole, and then the stopper rod sleeve is driven to reset by the padding ball and the elasticity of the spring itself, so that the stopper rod sleeve can generate high-frequency amplitude on the reinforced mesh cylinder, so as to facilitate the fall of impurities remaining on the stopper rod, facilitate the rapid cooling of the stopper rod, and improve the cooling effect.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] As attached Figure 1 - Figure 8 The cooling device of the water-cooled continuous casting stopper rod shown in the figure uses a diversion cooling assembly provided on the base 1 to gather the cooling water flow through the connecting pipe 8 and inject it into the stopper rod sleeve 5 through the bottom of the connecting pipe 8 to first cool the stopper rod sleeve 5. The spiral strips 15, guide holes 14 and reinforcement rings 16 embedded in the stopper rod sleeve 5 and the connecting pipe 8 facilitate the cooling water to be transported in a vortex shape in the connecting pipe 8 and the stopper rod sleeve 5, thereby improving the medium transportation efficiency. The water flow can be injected into the diversion cavity through the frame opening 13, and the water in the diversion cavity can be diverted through the water diversion inclined hole 11 and transported to the stopper rod sleeve 5. On the outside, the water flow delivered to the stopper sleeve 5 and the water flow outside the stopper sleeve 5 are combined to realize the function of wrapping and fully cooling the stopper sleeve 5. When the water guide plate 10 rotates, the padding ball 12 contacts the water diversion inclined hole 11, and then the stopper sleeve 5 is driven to reset by the padding ball 12 and the elasticity of the spring 7 itself, so that the stopper sleeve 5 can generate high-frequency amplitude on the reinforcing mesh cylinder 3, so that the impurities remaining on the stopper rod after the molten steel is delivered during water cooling of the stopper sleeve 5 can fall off, which facilitates the rapid cooling of the stopper rod and improves the cooling effect. The specific structural arrangement of the assembly is as follows;

[0029] The diversion cooling assembly includes a protective cover 2 provided on a base 1, with a reinforcing mesh tube 3 embedded inside the protective cover 2. The reinforcing mesh tube 3 includes a plurality of reinforcing ribs 4, and the reinforcing ribs 4 are staggered. A plurality of drainage holes are opened on the outside of the reinforcing mesh tube 3, and one end of each drainage hole extends to the outside of the protective cover 2. One end of the reinforcing mesh tube 3 is slidably connected to a plurality of stopper sleeves 5. The bottom ends of the plurality of stopper sleeves 5 are fixedly provided with a bottom plate 6, and the outer side of each stopper sleeve 5 is provided with a spring 7. The ends of the reinforcing mesh tube 3 are embedded with a plurality of connecting pipes 8 respectively located at the ends of the corresponding stopper sleeves 5.

[0030] One end of the reinforcing mesh tube 3 is provided with a supporting inclined seat 9, and a water guide plate 10 is installed on the end of the supporting inclined seat 9 facing the reinforcing mesh tube 3 by bolts. A plurality of water diversion inclined holes 11 are penetrated on the water guide plate 10, and a pad ball 12 is fixedly provided on one side of the plurality of bottom plates 6. The pad ball 12 extends to the surface of the water diversion inclined hole 11 and contacts the water diversion inclined hole 11. A plurality of frame openings 13 are provided on the outer side of the supporting inclined seat 9. A diversion cavity for conveying water flow is formed between the supporting inclined seat 9 and the water guide plate 10. The supporting inclined seat 9 is tilted downward, and the outer side of the water guide plate 10 extends to the inner wall of the protective cover 2 and is rotatably connected to the protective cover 2;

[0031] A guide hole 14 is provided in the middle of the connecting pipe 8, a spiral strip 15 is embedded in the interior of the stopper rod sleeve 5, and a reinforcing ring 16 for positioning the stopper rod is provided on the top of the spiral strip 15, and a medium delivery hole 17 for delivering the cooling medium is provided at the bottom of the stopper rod sleeve 5. A reinforced water inlet delivery pipe 27 is provided on the outer side of the medium delivery hole 17, and the reinforced water inlet delivery pipe 27 passes through the protective cover 2 and extends to the outside of the protective cover 2 and is slidably connected to the protective cover 2. A diversion hole body 18 is provided on the outside of the connecting pipe 8, and a retaining ring 19 is fixedly provided on the top of the reinforcing mesh cylinder 3. A first water inlet hole 20 connected to the diversion hole body 18 is provided on one end of the reinforcing mesh cylinder 3, and a first water inlet hole 20 connected to the diversion hole body 18 is provided on the outer side of the protective cover 2. There is a second water inlet hole 21 for injecting water, and the second water inlet hole 21 is located on one side of the water guide plate 10. A pressure ring 22 is provided on one side of the retaining ring 19, and a plurality of frame openings 13 are fixedly provided on the inner wall of the pressure ring 22. A plurality of screw rods 24 are threadedly connected to the pressure ring 22. The reinforced water inlet delivery pipe 27 passes through the retaining ring 19 and extends to the end of the reinforced mesh cylinder 3 and is rotatably connected to the reinforced mesh cylinder 3. Multiple retaining ring seats 23 are respectively located at one end of the corresponding connecting pipe 8. A rotating shaft 25 is fixedly provided on the side of the supporting inclined seat 9 away from the water guide plate 10. The rotating shaft 25 passes through the protective cover 2 and extends to the end of the protective cover 2, and a driving motor 26 for driving the rotating shaft 25 to rotate is provided at the end of the protective cover 2.

[0032] When using the above structure, the staff installs the device on the top of the molten iron ladle. According to the discharge requirements of the molten iron ladle, the number of stopper rods on each stopper rod sleeve 5 is increased or decreased. The stopper rods pass through the stopper rod sleeve 5 and the connecting pipe 8 and are screwed together with the reinforcing ring 16. The hydraulic device drives the device to move so that the stopper rods in the stopper rod sleeve 5 and the connecting pipe 8 can extend into the molten iron ladle to control the flow rate of molten iron.

[0033] During cooling, external high-pressure water is pumped into the first water inlet 20 and the second water inlet 21 through a water pump. The water delivered from the first water inlet 20 is injected into the connecting pipe 8 through the diverter hole 18. The cooling water flow is gathered through the connecting pipe 8 and injected into the stopper sleeve 5 through the bottom of the connecting pipe 8. This first cools the stopper sleeve 5 and also indirectly cools the stopper rod.

[0034] The cooling water flow injected into the protective cover 2 through the second water inlet hole 21 can be injected into the guide cavity through the frame opening 13. The water in the guide cavity can be diverted through the water diversion inclined hole 11 and transported to the outside of the stopper sleeve 5. The water flow transported into the stopper sleeve 5 and the water flow outside the stopper sleeve 5 are combined to achieve the function of wrapping and fully cooling the stopper sleeve 5. The water cooling can be directly connected to tap water, which can better reduce energy consumption. The used water can be used to cool the castings in subsequent processes, saving water resources and reducing costs.

[0035] At the same time, the driving motor 26 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the water guide plate 10 and the support inclined seat 9 to rotate. When the support inclined seat 9 rotates, the water in the diversion cavity can be sprayed out in a vortex shape through the water diversion inclined hole 11, so that the water can contact the stopper rod sleeve 5 and the water can be located between the water guide plate 10 and the protective cover 2, so that each stopper rod sleeve 5 and the reinforcing mesh cylinder 3 can be immersed in the cooling water, so that the cooling water can cool the stopper rod sleeve 5 and then be discharged through the drainage hole;

[0036] When the water guide plate 10 rotates, the original inclined position of the water guide plate 10 is changed, thereby enabling each stopper rod sleeve 5 to be displaced on the reinforcing mesh cylinder 3 one by one, compressing the spring 7, and allowing the remaining stopper rods to be extended one by one through the stopper rod sleeve 5 and the connecting pipe 8. This realizes the function of replacing stopper rods without stopping the machine, and can also cool the stopper rods stored in the device, thereby increasing the service life of the stopper rods.

[0037] When the water guide plate 10 rotates, the cushion ball 12 contacts the water diversion inclined hole 11, and then the stopper rod sleeve 5 is driven to reset by the cushion ball 12 and the elasticity of the spring 7, so that the stopper rod sleeve 5 can generate high-frequency amplitude on the reinforcing mesh tube 3, so that excess iron filings and impurities on the stopper rod can fall off, and the stopper rod is also easy to cool quickly.

[0038] At the same time, the spiral strips 15, guide holes 14 and reinforcement rings 16 embedded in the stopper sleeve 5 and the connecting pipe 8 facilitate the cooling water to be transported in a vortex shape in the connecting pipe 8 and the stopper sleeve 5, thereby improving the medium transportation efficiency;

[0039] At the same time, the screw rod 24, the pressure ring 22 and the retaining ring seat 23 are used to limit the installation of the connecting pipe 8 and the reinforcing net tube 3 on the protective cover 2, ensuring the stability and convenience of the installation of the reinforcing net tube 3 on the protective cover 2.

[0040] Different from the prior art, the present application discloses a cooling device for a water-cooled continuous casting stopper rod. The cooling water flow is gathered through the connecting pipe 8 and injected into the stopper rod sleeve 5 through the bottom of the connecting pipe 8 to first cool the stopper rod sleeve 5. The spiral strips 15, guide holes 14 and reinforcement rings 16 embedded in the stopper rod sleeve 5 and the connecting pipe 8 facilitate the cooling water to be transported in a vortex shape in the connecting pipe 8 and the stopper rod sleeve 5, thereby improving the medium transport efficiency. The water flow can be injected into the guide cavity through the frame opening 13, and the water in the guide cavity can be diverted and transported through the water diversion inclined hole 11. To the outside of the stopper sleeve 5, combined with the water flow delivered to the stopper sleeve 5 and the water flow outside the stopper sleeve 5, the stopper sleeve 5 is fully cooled in a wrapped manner. When the water guide plate 10 rotates, the padding ball 12 contacts the water diversion inclined hole 11, and then the stopper sleeve 5 is driven to reset by the padding ball 12 and the elasticity of the spring 7 itself, so that the stopper sleeve 5 can generate high-frequency amplitude on the reinforcing mesh tube 3, so that the impurities remaining on the stopper rod after the molten steel is delivered during water cooling of the stopper sleeve 5 can fall off, which makes it easy for the stopper rod to cool quickly and improve the cooling effect.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
