Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, and more specifically, to a sliding nozzle assembly device with a guide. Background Art

[0002] The sliding nozzle assembly device is mainly composed of upper and lower sliding plates made of refractory materials (and an intermediate sliding plate for the tundish sliding nozzle), a mechanical drive mechanism, and supporting upper and lower nozzles. It is installed on the outer bottom of the ladle or tundish. In steelmaking production, the sliding nozzle device plays a crucial role. It precisely controls the flow of molten steel from the ladle to the tundish and from the tundish to the mold, ensuring that the flow of molten steel can be reliably controlled like a valve, which greatly promotes the improvement of steel quality and production efficiency.

[0003] When the existing sliding nozzle assembly device is in use, the sliding plate moves along a straight path under the action of the drive mechanism to control and adjust the flow rate of the molten steel flowing through. However, when the sliding plate moves in the reverse direction, it is not convenient to adjust the angle of the sliding plate, and the sliding plate is likely to drive the molten steel to move in the reverse direction, resulting in poor use effects. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a sliding nozzle assembly device with a guide, aiming to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sliding nozzle assembly device with a guide, including a feeding frame. At both edge positions on the top of the feeding frame, vertical plates are fixedly connected. A moving component is arranged between the two vertical plates. The moving component includes a first self-locking motor, a lead screw, two sliding rods, and a slider. The first self-locking motor is fixedly installed on one side of one of the vertical plates, and the end of the output shaft of the first self-locking motor is fixedly connected to the lead screw. A rotating component is arranged at the bottom of the slider. The rotating component includes a connecting frame, a second self-locking motor, a rotating shaft, and a sliding plate. The second self-locking motor is fixedly installed at the inner bottom end of the connecting frame, and the end of the output shaft of the second self-locking motor is fixedly connected to the rotating shaft.

[0006] Further, one end of the lead screw penetrates through the slider and is threadedly connected thereto, and both ends of the lead screw are respectively movably connected to the two vertical plates through two bearings. One end of each of the two sliding rods penetrates through the slider, and both ends of the two sliding rods are respectively fixedly connected to the two vertical plates.

[0007] Further, the top of the connecting frame is fixedly connected to the slider. The rotating shaft is movably connected to the bottom end of the connecting frame through a bearing, and the bottom end of the rotating shaft passes through the top of the feeding frame and is fixedly connected to the sliding plate. The sliding plate is movably arranged inside the feeding frame.

[0008] Furthermore, a material guiding assembly is provided on the material feeding frame, and the material guiding assembly includes a first material guiding hopper, a second material guiding hopper, and a discharge pipe.

The second self-locking motor 402 is fixedly installed at the bottom end inside the connection frame 401, and the end of the output shaft of the second self-locking motor 402 is fixedly connected to the rotating shaft 403.

[0027] Further, one end of the lead screw 302 passes through the slider 304 and is threadedly connected thereto. The two ends of the lead screw 302 are respectively movably connected to the two vertical plates 2 through two bearings. One end of each of the two slide bars 303 passes through the slider 304, and the two ends of the two slide bars 303 are respectively fixedly connected to the two vertical plates 2. The top end of the connection frame 401 is fixedly connected to the slider 304. The rotating shaft 403 is movably connected to the bottom end of the connection frame 401 through a bearing, and the bottom end of the rotating shaft 403 passes through the top end of the material conveying frame 1 and is fixedly connected to the sliding plate 404. The sliding plate 404 is movably arranged inside the material conveying frame 1.

[0028] Further, a material guiding assembly is arranged on the material conveying frame 1. The material guiding assembly includes a first material guiding hopper 5, a second material guiding hopper 6, and a discharge pipe 7. The first material guiding hopper 5 is fixedly communicated with one side of the material conveying frame 1, and the second material guiding hopper 6 is fixedly communicated with the other side of the material conveying frame 1. The top end of the discharge pipe 7 is fixedly communicated with the second material guiding hopper 6. Symmetric side plates 8 are fixedly connected to the front and rear sides of the first material guiding hopper 5. Support seats 9 are fixedly connected to the bottom end of the material conveying frame 1 near the positions of the two side edges.

[0029] Among them, by providing the first material guiding hopper 5, it is convenient to guide the molten steel flowing in. The molten steel can enter the first material guiding hopper 5 through the top of the first material guiding hopper 5, or the first external pipeline can be connected to the two side plates 8, and the molten steel in the first external pipeline enters the first material guiding hopper 5 through one side of the first material guiding hopper 5.

Since the lead screw 302 is threadedly connected to the slider 304 and the two slide bars 303 limit the rotation of the slider 304, the lead screw 302 can drive the slider 304 to move horizontally, thereby driving the connection frame 401 to move horizontally, and further driving the sliding plate 404 to move horizontally. The molten steel is pushed to flow by the sliding plate 404. The second self-locking motor 402 is started.

The position of the sliding plate 404 is adjusted according to requirements, so as to adjust the contact area between the sliding plate 404 and the molten steel. When the sliding plate 404 is parallel to the lead screw 302, the resistance between the molten steel and the sliding plate 404 is the smallest. Similarly, the sliding plate 404 is driven to move in the reverse direction by reversing the first self-locking motor 301. The operation is simple, it is convenient to adjust the angle of the sliding plate 404, and the use effect is good.
