Description

Technical Field

[0001] This utility model relates to the field of continuous casting, specifically to a slag collection device during continuous casting. Background Technology

[0002] In the field of continuous casting of steel, the crystallizer is the core equipment for cooling and solidifying molten steel into billets, and the cleanliness of its internal environment directly determines the surface quality and internal properties of the billets.

[0003] During continuous casting, slag is generated on the surface of molten steel. If the slag falls into the crystallizer, it is easy to adhere to the surface of the billet and form defects such as inclusions and scale. In traditional continuous casting production, slag is mostly handled manually or with simple slag removal tools. There is a lack of a special anti-slag structure for the top of the crystallizer. Manual slag removal is not only inefficient, but also difficult to intercept dynamically generated slag in real time. Therefore, it is necessary to design a slag collection device in the continuous casting process to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a slag collection device for continuous casting process to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag collection device for continuous casting, comprising a crystallizer, a pouring pipe, and an mounting plate. The pouring pipe penetrates into the crystallizer. Two guide rods are installed at the bottom of the horizontal section of the mounting plate. A lifting channel is slidably connected to the outside of the guide rods. A collection box is fixedly installed at one end of the lifting channel. Multiple heat dissipation holes are provided on both the front and rear sides of the lifting channel. A heat dissipation component for blowing air into the lifting channel is installed on one side of the mounting plate. The bottom of the guide rod is equipped with an elastic component that connects to the lifting channel. A vertical plate is fixedly installed on the top surface of the lifting channel, and a drive component for lifting the vertical plate is installed on one side of the mounting plate.

[0006] Preferably, the heat dissipation assembly includes a connecting plate, which is fixedly installed on one side of the vertical section of the mounting plate, and a cooling fan is fixedly installed at the lower end of the connecting plate.

[0007] Preferably, the elastic component includes a baffle plate, which is fixedly installed at the lower end of the guide rod, and a spring is fixedly installed on the top surface of the baffle plate, with the upper end of the spring fixedly installed at the bottom of the lifting channel.

[0008] Preferably, the drive assembly includes a motor, which is mounted on one side of the mounting plate, and a cam that abuts against the top surface of the vertical plate is fixedly mounted on the output end of the motor.

[0009] Preferably, the outer side of the cam is tangent to the top surface of the vertical plate.

[0010] Preferably, the pouring pipe slides through the collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this continuous casting process, the slag collection device applies an upward elastic force to the lifting channel through a spring, so that the vertical plate keeps in contact with the bottom of the cam. When the motor is turned on, the cam is driven to rotate. The rotation of the cam abuts against the vertical plate, causing the lifting channel to move up and down continuously. This causes the collection box and the lifting channel to move up and down together, causing the slag to shake and slide down along the collection box and the lifting channel, thus ensuring the efficiency of slag collection.

[0012] 2. In this continuous casting process, the slag collection device uses a collection box positioned above the crystallizer. When the slag from the steel ladle and tundish falls, it lands inside the collection box and enters the lifting channel along the inclined collection box. The slag then flows through the lifting channel outlet into a container below the outlet. During this process, a cooling fan blows air into the lifting channel through the cooling holes to cool the slag and prevent it from overheating and damaging the container.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please refer to Figure 1-3As shown, this utility model provides a slag collection device for continuous casting process, including a crystallizer 1, a pouring pipe 2 and a mounting plate 3. The pouring pipe 2 is inserted into the crystallizer 1. Two guide rods 4 are installed at the bottom of the horizontal section of the mounting plate 3. A lifting channel 5 is slidably connected to the outside of the guide rods 4. A collection box 6 is fixedly installed at one end of the lifting channel 5. Multiple heat dissipation holes 7 are opened on both the front and rear sides of the lifting channel 5. A heat dissipation component for blowing air into the lifting channel 5 is installed on one side of the mounting plate 3. The bottom of the guide rod 4 is equipped with an elastic component that connects to the lifting channel 5. A vertical plate 12 is fixedly installed on the top surface of the lifting channel 5. A drive component for lifting the vertical plate 12 is installed on one side of the mounting plate 3.

[0017] Specifically, the collection box 6 blocks the top of the crystallizer 1 to prevent steel slag from falling directly into the crystallizer 1, the heat dissipation component dissipates heat from the steel slag in the lifting channel 5, and the drive component ensures the efficiency of steel slag discharge.

[0018] The heat dissipation component includes a connecting plate 8, which is fixedly installed on one side of the vertical section of the mounting plate 3. A cooling fan 9 is fixedly installed at the lower end of the connecting plate 8. When the switch of the cooling fan 9 is turned on, the cooling fan 9 blows air into the lifting channel 5 through the heat dissipation hole 7, thereby dissipating heat from the steel slag in the lifting channel 5.

[0019] The elastic component includes a baffle 10, which is fixedly installed at the lower end of the guide rod 4. A spring 11 is fixedly installed on the top surface of the baffle 10. The upper end of the spring 11 is fixedly installed at the bottom of the lifting channel 5. The lifting channel 5 is supported by the elastic force of the spring 11. The spring 11 applies an upward force to the lifting channel 5, so that the vertical plate 12 is pressed against the cam 14.

[0020] The drive assembly includes a motor 13, which is mounted on one side of the mounting plate 3. A cam 14 is fixedly mounted on the output end of the motor 13, which abuts against the top surface of the vertical plate 12. The outer side of the cam 14 is tangent to the top surface of the vertical plate 12. When the motor 13 is turned on, the cam 14 is driven to rotate. The cam 14 rotates and abuts against the vertical plate 12, causing the lifting channel 5 to move up and down continuously. This causes the collection box 6 and the lifting channel 5 to move up and down together, causing the steel slag to shake and slide down along the collection box 6 and the lifting channel 5, thus ensuring the efficiency of steel slag collection.

[0021] Wherein: the pouring pipe 2 slides through the collection box 6, so that the collection box 6 can move up and down on the outside of the pouring pipe 2.

[0022] Working principle: This utility model is a slag collection device in the continuous casting process. The collection box 6 is blocked above the crystallizer 1. When the slag in the steel drum and tundish falls, it will fall into the collection box 6 and enter the lifting channel 5 along the inclined collection box 6. The slag is discharged into the container below the outlet of the lifting channel 5 through the outlet of the lifting channel 5. During this process, the cooling fan 9 blows air into the lifting channel 5 through the heat dissipation hole 7 to cool the slag. The spring 11 applies an upward elastic force to the lifting channel 5, keeping the vertical plate 12 in contact with the bottom of the cam 14. When the motor 13 is turned on, the cam 14 is driven to rotate. The rotating cam 14 abuts against the vertical plate 12, causing the lifting channel 5 to move up and down continuously. This causes the collection box 6 and the lifting channel 5 to move up and down together, causing the steel slag to shake and slide down along the collection box 6 and the lifting channel 5, thus ensuring the efficiency of steel slag collection.
