[0002] In the steel smelting process, the tundish is an important transition container for molten steel to flow from the ladle to the crystallizer. Its design and performance directly affect the quality and efficiency of continuous casting production. During production, the molten steel is transferred from the ladle to the tundish through the conveying pipeline, and the tundish is fed and then distributed to each crystallizer. The equipment or system has achieved the purpose of moving the molten steel. However, the moving device in the prior art still has certain defects that need to be improved.

[0003] The moving device in the prior art is used. Since the molten steel is directly injected into the tundish, it is easy to cause uneven flow of the molten steel. The ability to regulate the flow of the molten steel is limited, and it is difficult to achieve uniform distribution of the molten steel in the tundish, which in turn affects the uniformity of the composition of the molten steel and the removal effect of inclusions. In addition, due to the singleness of the molten steel injection point, it is easy to cause uneven temperature distribution in the tundish, which affects the solidification effect of the molten steel and the quality of the continuous casting billet. Therefore, a tundish moving device is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to solve the defect of single molten steel entry point in the prior art during feeding, and proposes a tundish moving device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The diversion column is connected to the tundish body, a diversion groove is provided inside the diversion column, flow guide pipes are passed through both sides of the bottom of the diversion column, two water outlet pipes are equidistantly passed through the two flow guide pipes, and a first connecting guide channel is provided in the flow guide pipe and the two water outlet pipes.

[0008] Two wedge blocks are installed inside the diversion trough, and C-shaped tubes are passed through both sides of the top of the diversion column. The bottom ends of the two C-shaped tubes are connected to a diversion plate, and the bottom of the diversion plate is connected to two connecting tubes. A second guide channel is opened in the C-shaped tube, the diversion plate and the connecting tube.

[0009] Preferably, a molten steel inlet is provided at the top of the tundish body, and a delivery pipeline is connected to the molten steel inlet.

[0010] Preferably, a water inlet is provided at the top of the diversion column, and the water inlet is located at the top of the diversion trough and is connected to the diversion trough.

[0011] Preferably, the bottom end of the delivery pipe is connected to the water inlet.

[0012] Preferably, the two wedge blocks correspond to the positions of the two second guide paths, and the wedge block is located in the middle of the diverter groove.

[0013] Preferably, the two connecting pipes are respectively located on both sides of the guide pipe, and the distance between the connecting pipe and the water outlet pipe is equal to the distance between the water outlet pipe and the first guide channel.

[0014] The utility model has the following beneficial effects:

[0015] 1. Under the cooperation of the guide pipe and the diversion column, the molten steel flows out of the ladle and is transported to the diversion groove through the conveying pipeline, enters the first guide channel, and is discharged from the two outlet pipes at the bottom of the guide pipe, so that the molten steel can be diverted to different positions inside the tundish body, effectively guiding the flow direction and path of the molten steel. The distribution of the molten steel in the tundish body is more uniform, which is beneficial to the subsequent process treatment and processing, and can improve product quality and production efficiency in the production process, and reduce the eddy current and turbulence of the molten steel;

[0016] 2. With the cooperation of the C-shaped tube and the wedge block, when the molten steel enters the diversion trough from the water inlet, it is first blocked by the wedge block in the middle of the diversion trough, so that the impact force of the molten steel is reduced when it falls into the diversion trough, and a part of the molten steel is guided to the inside of multiple connecting pipes in the second guide channel and then discharged.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 A tundish moving device includes a tundish body 1, a molten steel inlet 101 is opened on the top of the tundish body 1, a conveying pipe 2 is connected to the molten steel inlet 101, and the conveying pipe 2 can enter the tundish body 1 from the molten steel inlet 101. The tundish body 1 is penetrated by the conveying pipe 2, and the bottom end of the conveying pipe 2 is connected to the water inlet 302, so that the molten steel conveyed by the conveying pipe 2 can enter the diverter column 3 from the water inlet 302.

[0024] A water inlet 302 is provided on the top of the diverter column 3. The water inlet 302 is located at the top of the diverter slot 301 and is connected to the diverter slot 301, so that the molten steel transported through the conveying pipeline 2 can enter the diverter slot 301 from the water inlet 302. The diverter column 3 is connected to the tundish body 1. The diverter slot 301 is provided inside the diverter column 3. Both sides of the bottom of the diverter column 3 are penetrated by guide pipes 4. Two outlet pipes 5 are equidistantly penetrated on the two guide pipes 4. The guide pipes 4 and the two outlet pipes 5 are connected to the tundish body 1. A first interconnected guide channel 6 is opened in the water pipe 5. The top of the conveying pipe 2 is connected to the ladle, and the bottom enters the ladle body 1 from the molten steel inlet 101 and is connected to the inside of the water inlet 302. At this time, the molten steel flows out of the ladle and is transported to the diversion groove 301 through the conveying pipe 2. At this time, it enters the first guide channel 6 and is guided by the guide pipe 4 and discharged from the two water outlet pipes 5 at the bottom of the guide pipe 4, so that the molten steel can be guided to different positions inside the ladle body 1.

[0025] Two wedge blocks 7 are installed inside the diverter trough 301. The two wedge blocks 7 correspond to the positions of the two second guide channels 11, so that after the molten steel passes through the obstruction of the wedge blocks 7 to reduce the impact force, part of the molten steel can be guided into the second guide channel 11 along with the wedge blocks 7, and the wedge blocks 7 are located in the middle of the diverter trough 301. C-shaped tubes 8 are passed through both sides of the top of the diverter column 3. The bottom ends of the two C-shaped tubes 8 are connected to diverter plates 9. The bottom of the diverter plate 9 is connected to two connecting tubes 10. The two connecting tubes 10 are respectively located on both sides of the guide pipe 4, and the distance between the connecting tube 10 and the outlet pipe 5 is equal to the distance between the outlet pipe 5 and the first guide channel 6. In order to more evenly control the outflow of molten steel when guiding the molten steel, a second guide channel 11 is provided in the C-shaped tube 8, the diverter plate 9 and the connecting tube 10. When the molten steel enters the diverter trough 301 from the water inlet 302, it is first partially blocked by the wedge block 7 in the middle of the diverter trough 301, so that the impact force of the molten steel is reduced when falling into the diverter trough 301. Since the wedge block 7 is wedge-shaped, a part of the molten steel can be guided to the second guide channel 11 and diverted to the inside of multiple connecting tubes 10 through the C-shaped tube 8 and the diverter plate 9 and then discharged, thereby reducing the friction and impact between the molten steel and the conveying pipeline 2 and reducing the loss of molten steel.
