Description

Technical Field

[0001] This utility model belongs to the field of steel casting technology, and specifically relates to a crystallizer water distribution and adjustment device. Background Technology

[0002] A crystallizer is a continuous steel casting device that receives molten steel poured from an intermediate ladle and solidifies it into a solid billet shell according to a specified cross-sectional shape.

[0003] Currently, Chinese utility model patent CN208033608U discloses a continuous casting crystallizer. Existing continuous casting crystallizers typically use water spraying in the secondary cooling section for forced cooling of the billet. However, the water volume distribution in the secondary cooling section is uneven, failing to adequately cool the billet. Furthermore, it is difficult to precisely adjust the water volume according to the actual state of the billet, leading to a higher risk of cracking during continuous casting. Additionally, the cross-sectional shape of the billet is primarily determined by the mold inside the crystallizer. Processing billets of different shapes requires disassembling the original mold and replacing it with the required mold, which is cumbersome and affects the processing efficiency of steel casting. Utility Model Content

[0004] The purpose of this invention is to provide a crystallizer water distribution adjustment device, which has the advantages of improving the uniformity of water cooling in the secondary cooling section and allowing the mold to be adjusted left and right to the required slot shape for solidification and shaping of molten steel.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a crystallizer water distribution and adjustment device, including a crystallizer, with arc-shaped plates welded to both sides of the bottom of the crystallizer, and a roller rotatably connected between the two arc-shaped plates. A sealing cover welded to the arc-shaped plates is provided on one side of the roller, and a cooling water pipe is provided on one side of the crystallizer. A distribution pipe is fixedly connected to the bottom of the cooling water pipe, and a connecting pipe is fixedly connected to the side of the distribution pipe near the roller. A water injection pipe fixedly connected to the sealing cover is fixedly connected to the end of the connecting pipe away from the distribution pipe. A water inlet groove communicating with the inside of the sealing cover is opened inside the roller, and a cooling hole communicating with the inside of the water inlet groove is opened on the surface of the roller.

[0006] By employing the above technical solution, cooling water is delivered to the interior of the rolls, allowing for forced cooling of different positions on the top and bottom of the billet during its movement. This enables precise adjustment of the water distribution, improving the uniformity of billet cooling and reducing the risk of cracking during continuous casting. Furthermore, by creating multiple mold slots of different shapes on the top of the casting mold, the molten steel can be solidified into the corresponding cross-sectional shape when the mold slot is slid to the pouring gate. This eliminates the need for repeated mold disassembly and replacement, improving the processing efficiency of steel casting.

[0007] The present invention is further configured such that: a casting mold is slidably connected through the interior of the crystallizer; a first mold groove and a second mold groove are respectively opened on the top of the casting mold; a motor is bolted to one side of the outside of the crystallizer; a bevel gear rotatably connected to the output end of the motor is bolted to the output end of the motor; a bevel rack meshing with the bevel gear is bolted to the side of the casting mold near the motor; and rotating disks slidably connected to the casting mold are rotatably connected to both sides of the interior of the crystallizer.

[0008] Using the above technical solution, the mold can be adjusted left and right to the required groove shape to solidify and shape the molten steel, without the need for repeated disassembly and replacement of the mold.

[0009] The present invention is further configured such that: the top of the crystallizer is bolted with a pouring port that is slidably connected to the casting mold, and the first mold groove and the second mold groove can be respectively opened into a strip shape, a square shape, or a circle shape.

[0010] By adopting the above technical solution, the bottom of the pouring port is embedded into the top of the casting mold, thereby preventing molten steel from seeping out.

[0011] The present invention is further configured such that: cooling water chambers are provided on both sides inside the crystallizer, and the top of the cooling water pipe is fixedly connected to a three-way valve that is connected to the two cooling water chambers respectively.

[0012] By adopting the above technical solution, cooling water is injected into the cooling water chamber through a three-way valve, thereby condensing and solidifying the molten steel inside the casting mold into a casting billet.

[0013] The present invention is further configured such that: a temperature-conducting plate welded to the crystallizer is provided on the side of the cooling water cavity near the casting mold, and drain valves communicating with the interior of the cooling water cavity are bolted to both sides of the outside of the crystallizer.

[0014] By employing the above technical solution, the temperature conduction and exchange efficiency can be improved using the heat-conducting plate, thereby enabling the molten steel to condense rapidly. Simultaneously, the drain valve allows the water that has heated up inside the cooling water chamber to be drained, allowing for the refilling of cooling water.

[0015] The present invention is further configured such that a sealing ring, which is bonded to the same arc-shaped plate, is slidably sleeved at one end of the roller surface near the sealing cover.

[0016] By adopting the above technical solution, the sealing performance is improved, and the leakage of cooling water inside the sealing cover is prevented.

[0017] The present invention is further configured such that: a water volume sensor is fixedly connected to one end of the cooling water pipe near the distribution pipe and the three-way valve, and a distribution valve is fixedly connected between the distribution pipe and the connecting pipe.

[0018] The above technical solution facilitates real-time monitoring of the water flow in the crystallizer and the secondary cooling zone, thereby controlling the opening and closing of the distribution valve and achieving precise control of the cooling water volume in the crystallizer and the secondary cooling zone.

[0019] The present invention is further configured such that a controller, which works in conjunction with a water volume sensor and a distribution valve, is bolted to one side of the outside of the crystallizer.

[0020] By adopting the above technical solution, the water distribution in the crystallizer and the secondary cooling zone is automatically adjusted, the cooling effect is optimized, the sensitivity of the billet to cracking is reduced, and the quality of the billet is improved.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By supplying cooling water to the inside of the rolls, forced cooling can be applied to different locations on the top and bottom of the billet as it moves across the rolls. This allows for precise adjustment of the water distribution, improving the uniformity of billet cooling and reducing the risk of cracking during continuous casting.

[0023] 2. By creating multiple mold slots of different shapes on the top of the casting mold, the molten steel can be solidified into the corresponding cross-sectional shape when the mold slot is slid to the pouring gate. This eliminates the need for repeated mold disassembly and replacement, improving the processing efficiency of steel casting. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] refer to Figure 1 , Figure 2 , Figure 3 A crystallizer water distribution and adjustment device includes a crystallizer 1. Arc-shaped plates 2 are welded to both sides of the bottom of the crystallizer 1. A roller 3 is rotatably connected between the two arc-shaped plates 2. A sealing cover 4 welded to the arc-shaped plates 2 is provided on one side of the roller 3. A cooling water pipe 5 is provided on one side of the crystallizer 1. A distribution pipe 6 is fixedly connected to the bottom of the cooling water pipe 5. A connecting pipe 7 is fixedly connected to the side of the distribution pipe 6 near the roller 3. A water injection pipe 8 fixedly connected to the sealing cover 4 is fixedly connected to the end of the connecting pipe 7 away from the distribution pipe 6. A water inlet groove 10 communicating with the inside of the sealing cover 4 is opened inside the roller 3. Cooling holes 9 communicating with the inside of the water inlet groove 10 are opened on the surface of the roller 3. Cooling water is delivered to the inside of the roller 3, thereby forcibly cooling different positions at the top and bottom of the billet during the movement of the roller 3 over the billet. This allows for precise adjustment of the water distribution, improves the uniformity of billet cooling, and reduces the risk of cracking in the billet during continuous casting.

[0031] refer to Figure 3 The top of the crystallizer 1 is bolted with a pouring port 18 that is slidably connected to the casting mold 11. The first mold groove 12 and the second mold groove 13 can be respectively opened into a strip shape, a square shape, or a circle shape. The bottom of the pouring port 18 is embedded into the top of the casting mold 11, thereby preventing molten steel from seeping out.

[0032] refer to Figure 1 , Figure 3 Cooling water chambers 19 are provided on both sides inside the crystallizer 1. The top of the cooling water pipe 5 is fixedly connected to a three-way valve 20 that is connected to the two cooling water chambers 19 respectively. Cooling water is injected into the cooling water chambers 19 through the three-way valve 20, so that the molten steel inside the casting mold 11 can be condensed and shaped into a casting billet.

[0033] refer to Figure 1 , Figure 3 A temperature-conducting plate 21, welded to the crystallizer 1, is provided on the side of the cooling water chamber 19 near the casting mold 11. Drain valves 22, communicating with the interior of the cooling water chamber 19, are bolted to both sides of the outside of the crystallizer 1. The temperature-conducting plate 21 improves the efficiency of temperature conduction and exchange, allowing the molten steel to condense quickly. Simultaneously, the drain valves 22 drain the water that has risen in temperature inside the cooling water chamber 19, allowing for the refilling of cooling water.

[0034] refer to Figure 2 A sealing ring 23, which is bonded to the arc-shaped plate 2, is slidably sleeved on one end of the surface of the roll 3 near the sealing cover 4. This improves the sealing performance and prevents cooling water from leaking out of the sealing cover 4.

[0035] Brief description of the usage process: Cooling water is delivered to the interior of the three-way valve 20 and the distribution pipe 6 through the cooling water pipe 5. After entering the cooling water chamber 19, the cooling water can condense the molten steel inside the casting mold 11 into a billet. Then, the billet is conveyed downward through the roller 3, and the cooling water is delivered to the interior of the sealing cover 4 through the water injection pipe 8 via the distribution pipe 6 and the connecting pipe 7. When the roller 3 rotates to convey the billet, the cooling water inside the sealing cover 4 can be sprayed out on the surface of the roller 3 through the water inlet trough 10 and the cooling hole 9, thereby cooling and reducing the temperature of different positions at the top and bottom of the billet during conveying.

[0036] Example 2:

[0037] refer to Figure 1 , Figure 3 A crystallizer water distribution and adjustment device is disclosed. A casting mold 11, slidably connected through the interior of the crystallizer 1, is disclosed. The top of the casting mold 11 has a first mold groove 12 and a second mold groove 13. A motor 14 is bolted to one side of the crystallizer 1. A bevel gear 15, rotatably connected to the crystallizer 1, is bolted to the output end of the motor 14. A bevel rack 16, meshing with the bevel gear 15, is bolted to the side of the casting mold 11 closest to the motor 14. Rotary disks 17, slidably connected to the casting mold 11, are rotatably connected to both sides of the interior of the crystallizer 1. By opening multiple mold grooves of different shapes on the top of the casting mold 11, molten steel can be solidified into a corresponding cross-sectional shape when the corresponding mold groove is slid to the pouring gate. This eliminates the need for repeated mold disassembly and replacement, improving the processing efficiency of steel casting.

[0038] refer to Figure 1 A water flow sensor 24 is fixedly connected to one end of the cooling water pipe 5 near the distribution pipe 6 and the three-way valve 20. A distribution valve 25 is fixedly connected between the distribution pipe 6 and the connecting pipe 7. This facilitates real-time monitoring of the water flow in the crystallizer and the secondary cooling zone, thereby controlling the opening and closing of the distribution valve 25 to achieve precise control of the cooling water volume in the crystallizer and the secondary cooling zone.

[0039] refer to Figure 1 A controller 26, which works in conjunction with a water flow sensor 24 and a distribution valve 25, is bolted to one side of the outside of the crystallizer 1. This controller automatically adjusts the water distribution in the crystallizer and the secondary cooling zone, optimizing the cooling effect, reducing the susceptibility of the cast billet to cracks, and improving the quality of the cast billet.

[0040] Brief description of the usage process: A first mold groove 12 and a second mold groove 13 are opened on the top of the casting mold 11. The first mold groove 12 and the second mold groove 13 can be opened into various different shapes such as strip, square, and circle. Then, by turning on the motor 14, the bevel gear 15 is rotated and meshes with the bevel rack 16. Under the rotation support of the rotating disk 17, the casting mold 11 slides left and right inside the crystallizer 1, moving the first mold groove 12 or the second mold groove 13 to the bottom of the pouring port 18. The molten steel is then shaped into the corresponding cross-sectional shape by passing through the various shapes opened inside the first mold groove 12 or the second mold groove 13.
