Description

Technical Field

[0001] The invention relates to the technical field of crystallizers for continuous casting equipment, and in particular to a crystallizer for continuous casting. Background Art

[0002] The continuous casting crystallizer is a very critical component of the continuous casting machine. Its main function is to gradually solidify the high-temperature molten steel in the crystallizer into a shell of the required specifications and shape. The crystallizer controls the solidification process of the molten steel by forced water cooling to ensure the quality of the ingot and the smooth progress of the continuous casting process. The crystallizer includes a vibration device and a crystallization device. The vibration device drives the crystallization device to vibrate so that the shell is separated from the crystallizer wall to prevent breaking and steel leakage. A copper plate is provided in the crystallization device. The molten steel contacts the copper plate and cools rapidly to form a shell. The molten steel will form the shape of the copper plate inside the crystallizer. Then, the required steel can be obtained by cutting the shaped steel.

[0003] The molten steel passes through the channel composed of steel plates inside the crystallizer to form a shape composed of spliced ​​steel plates. When it is necessary to manufacture steel billets of different shapes and sizes, the traditional crystallizer can only adjust the width of the steel plate billet. It is difficult to adjust the size of the steel bar when making steel bars. It can only be adjusted by replacing the mold in the crystallizer. On the one hand, replacing the mold is time-consuming. On the other hand, the steel bar can only obtain the size of the mold and cannot be flexibly adjusted according to specific needs. Summary of the invention

DETAILED DESCRIPTION

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0017] like Figure 1 to Figure 7 As shown, this embodiment proposes a crystallizer for continuous casting, including a frame 1, a through port 3, a sliding mechanism, a shaping mechanism and a water supply mechanism. A plurality of driving shafts 2 are arranged on both sides of the frame 1. Two through ports 3 are arranged, and the two through ports 3 are respectively opened on the upper and lower sides of the frame 1. A plurality of sliding mechanisms are arranged, and the plurality of sliding mechanisms are arranged in a circle inside the frame 1. A shaping mechanism is arranged on the sliding mechanism, and the sliding mechanism is used to drive the shaping mechanism to slide on the frame 1. There are a plurality of shaping mechanisms, and the shaping mechanisms correspond to the sliding mechanisms one by one. The plurality of shaping mechanisms are slidably connected, and the shaping mechanism is used to cool and shape the molten steel. The water supply mechanism is arranged on the frame 1, and the water supply mechanism is connected to the plurality of shaping mechanisms. The water supply mechanism is used to supply water to the shaping mechanism for cooling. The vibration device drives the frame 1 to vibrate through the driving shaft 2, thereby driving the shaping mechanism to vibrate. During use, the water supply mechanism injects water into the shaping mechanism to forcefully cool it, and cools the molten steel. The sliding mechanism is used to drive the cooling plate 9 to slide in both the horizontal and longitudinal directions, thereby changing the size of the steel while ensuring that the shape of the steel remains unchanged.

[0018] like Figure 1~Figure 4 As shown, the sliding mechanism includes a slide rail 4, a driving cylinder 5 and a slide seat 6. The slide rail 4 is fixedly arranged on the frame 1. A plurality of driving cylinders 5 are provided. The plurality of driving cylinders 5 are fixedly arranged on the frame 1. The driving cylinder 5 is arranged on the side of the slide rail 4. The slide seat 6 is slidably arranged on the slide rail 4. The output end of the driving cylinder 5 is connected to the slide seat 6. In this embodiment, four sliding mechanisms are provided. The four sliding mechanisms are arranged in four directions of up, down, left and right in the frame 1. The slide seat 6 slides on the slide rail 4 through the driving cylinder 5. The slide seat 6 drives the shaping mechanism to slide while sliding. The four shaping mechanisms adjust the size of the steel and slide under the drive of the slide seat 6, thereby keeping the position of the four cooling plates 9 at the center of the through-port 3.

[0019] like Figure 1 to Figure 7 As shown, the shaping mechanism is fixedly arranged on the slide seat 6, and a limited support arm 7 is arranged on the side of the slide seat 6. The shaping mechanism includes a driving cylinder 2 8, a cooling plate 9 and a cooling component. A plurality of driving cylinders 2 8 are arranged, and a plurality of driving cylinders 2 8 are fixedly arranged on the slide seat 6. The cooling plate 9 is arranged on the output end of the driving cylinder 2 8. The water supply mechanism is connected to the cooling plate 9, and an inclination angle is arranged on one side of the cooling plate 9. The cooling component is arranged on the cooling plate 9. The cooling component is used to quickly and evenly cool the molten steel. A slide rail 2 10 is arranged on the cooling plate 9, and the slide rail 2 10 is slidably connected with the limited support arm 7 located on the side of the slide seat 6. In this embodiment, two driving cylinders are arranged, and the two driving cylinders 2 8 push the cooling plate 9 to slide. The cooling plate 9 can move in the direction close to and away from the through port 3 under the push of the driving cylinder 2 8. At the same time, the cooling plate 9 is driven by the output end of the driving cylinder 1 5 to slide on the sliding seat 6. The cooling plate 9 slides with the limiting arm 7 on the adjacent sliding seat 6 through the sliding rail 2 10. At the same time, the limiting arm 7 fixes and stabilizes the cooling plate 9. The sliding direction of the adjacent sliding seat 6 is the same as the sliding direction of the cooling plate 9 pushed by the driving cylinder 2 8, and the sliding distance is also the same. The limiting arm 7 can make the corresponding positions and sliding distances of the four cooling plates 9 the same, which can avoid the four cooling plates 9 having different sliding distances, resulting in gaps between the cooling plates 9 and causing the molten steel to flow out.

[0020] like Figure 4~Figure 7 As shown, the cooling component includes a return water channel 11, a copper plate 12, a water inlet pipe 13 and a water outlet pipe 14. The return water channel 11 is opened on the cooling plate 9. The copper plate 12 is fixedly arranged on the cooling plate 9 on a side away from the driving cylinder 2 8. The copper plate 12 is in contact with the return water channel 11. The water inlet pipe 13 is arranged on the cooling plate 9. The water inlet pipe 13 is connected to the return water channel 11. The water outlet pipe 14 is arranged on the cooling plate 9. The water outlet pipe 14 is connected to the return water channel 11. The water inlet pipe 13 is connected to a side of the return water channel 11 close to the through port 3, and the water outlet pipe 14 is connected to a side of the return water channel 11 away from the through port 3. The layout of the return water channel 11 is as shown in FIG. Figure 7 As shown, the water inlet pipe 13 and the water outlet pipe 14 are both connected to the return water channel 11 at the center of the cooling plate 9, and the water flowing into the water inlet pipe 13 in the return water channel 11 needs to pass through the entire return water channel 11 and then flow through the water outlet pipe 14 to leave. The water preferentially cools the side of the cooling plate 9 close to the inclination angle to ensure that the copper plate 12 can fully cool down the molten steel and shape it.

[0021] like Figure 6~Figure 7As shown, one end of the cooling plate 9 with an inclined angle is fitted with a copper plate 12 provided on another adjacent cooling plate 9, and a clamping plate 15 is provided on the side of the cooling plate 9 close to the inclined angle. The clamping plate 15 is slidably connected to the adjacent cooling plate 9. The clamping plate 15 fixes the adjacent cooling plate 9 thereto, so that when the two cooling plates 9 slide, a small gap is left between them to ensure the shape of the steel.

[0022] like Figure 3~Figure 5 As shown, the water supply mechanism includes a water supply pipe 16 and a return pipe 17. The water supply pipe 16 is arranged on the frame 1, and the water supply pipe 16 is connected to the water inlet pipes 13 on multiple cooling plates 9. The return pipe 17 is arranged on the frame 1, and the return pipe 17 is connected to the water outlet pipes 14 on multiple cooling plates 9. A water trough 18 is opened on the frame 1, and the water supply pipe 16 and the return pipe 17 extend out of the frame 1 through the water trough 18. The water supply pipe 16 and the return pipe 17 are both arranged in a ring shape, and the water supply pipe 16 and the return pipe 17 are respectively arranged on both sides of the cooling plate 9. The water supply pipe 16 is connected to four water inlet pipes 13, and the return pipe 17 is connected to four water outlet pipes 14. One end of the water supply pipe 16 and one end of the return pipe 17 leave the frame 1 through the water trough 18 and are connected to the external waterway, and the copper plate 12 is forced to cool down by continuously introducing circulating water.

[0023] like Figure 4~Figure 7 As shown, the cooling plate 9 is perpendicular to other cooling plates 9 in contact with each other, the centers of the plurality of cooling plates 9 are aligned with the through port 3, the four cooling plates 9 form a rectangle, and the side of each cooling plate 9 is in contact with the copper plate 12 on the adjacent cooling plate 9, so that when the size of the steel is enlarged, the portion of the cooling plate 9 that is not in contact with the molten steel can come into contact with the molten steel by sliding, and the four cooling plates 9 slide at the same time, so that when the shape of the steel remains determined, the four cooling plates 9 are always kept in the center of the through port 3, and will not affect the position where the molten steel flows down.

[0024] In summary, the working principle of the continuous casting crystallizer is: The vibration device in the crystallizer drives the frame 1 to vibrate by connecting with the driving shaft 2. During the production process, the molten steel flows to the copper plate 12, and the water supply pipe 16 is connected with the external waterway. The water flows into the four water inlet pipes 13 through the water supply pipe 16. After entering the water inlet pipe 13, the water enters the return water channel 11. The water flows evenly in the return water channel 11. After passing the side of the cooling plate 9 close to the through port 3, the water flows through the other side of the cooling plate 9, and then flows into the outlet pipe 14. The water is discharged from the frame 1 through the return water pipe 17. The water preferentially cools the side of the cooling plate 9 close to the through port 3. When it is necessary to adjust the size of the steel forming to be larger, the output ends of the driving cylinder 1 5 and the driving cylinder 2 8 are shortened at the same time, and the output end of the driving cylinder 2 8 pulls the cooling plate 9 to move away from the through port 3. The output end of the driving cylinder 1 5 pulls the cooling plate 9 to slide in the direction of the cooling plate 9 abutting against it. All the cooling plates 9 slide against each other, and the side of the cooling plate 9 with an inclination angle is arranged on the copper abutting against it. The plate 12 slides, and more area on each copper plate 12 is in contact with the molten steel. Similarly, when the size of the steel needs to be reduced, the output ends of the drive cylinder 1 5 and the drive cylinder 2 8 are extended at the same time, pushing the four cooling plates 9 closer to each other, thereby reducing the rectangle formed by the four cooling plates 9. At the same time, the limit arm 7 on the sliding seat 6 at the installation position of one of the cooling plates 9 is slidably connected to the slide rail 2 10 on the cooling plate 9 abutted thereon. The limit arm 7 can fix the position of the cooling plate 9 to prevent the cooling plate 9 from shaking during use, and can also ensure that the horizontal sliding distance of the two cooling plates 9 is equal to the longitudinal sliding distance. Since the output ends of each drive cylinder 2 8 and the drive cylinder 1 5 are shortened at the same time, the rectangle formed by the four cooling plates 9 is always in the center of the through port 3. When the molten steel flows down, there is no need to adjust the position of the molten steel flow. The vibration device drives the frame 1 to vibrate. When the molten steel contacts the copper plate 12, the surface is cooled and the steel moves downward through the through port 3 under the action of vibration.

[0025] 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 protection scope of the present invention.
