Description

Technical Field

[0001] This utility model relates to the field of steelmaking production technology, specifically to a device for guiding sand into the ladle at the tapping position of a converter. Background Technology

[0002] In the steelmaking process, continuous casting is a crucial step in the high-temperature molten steel forming and casting process. To ensure continuous production of the continuous casting machine, an intermediate ladle is installed below the molten steel ladle. After the molten steel ladle is poured, the molten steel in the intermediate ladle is used to ensure the continuous cooling and forming of the crystallizer, waiting for the next heat of molten steel. Each time, the molten steel is supplied to the intermediate ladle from the previous steelmaking process, ensuring the continuous long-term operation of the continuous casting machine. The interior of the ladle is lined with refractory materials. After the refractory material is laid, it must undergo high-temperature baking and drying treatment before high-temperature molten steel can be poured in. The ladle has a sluice gate at the bottom, and the opening and closing of the sluice gate is controlled by a sliding plate mechanism. Before the molten steel from the converter tapping position enters the ladle, a large amount of diverting sand must be piled up at the sluice gate to ensure that the molten steel can flow smoothly out of the ladle sluice gate and into the intermediate tank each time the sliding plate mechanism controls the opening and closing of the sluice gate. Currently, when adding diverting sand, it is generally done manually to accurately put the diverting sand into the designated position inside the ladle, which makes the operation very difficult. Each time it is added, it is very easy to make a mistake in adding the sand and waste a lot of diverting sand, thus affecting the smooth operation of the converter production process. Utility Model Content

[0003] This invention provides a ladle sand-filling device for the tapping position of a converter to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A ladle sand-guiding and sand-filling device for the tapping position of a converter includes a motor installed on the outside of the ladle, the motor being connected to a winch drum, the winch drum being connected to a horn-shaped discharge port at the top of the ladle via a wire rope, the horn-shaped discharge port being connected to a discharge pipe, and the discharge pipe being positioned opposite the drain outlet of the ladle.

[0006] Furthermore, a transition roller is provided on the outer side of the ladle, and the wire rope and the transition roller are arranged in a winding manner.

[0007] Furthermore, the bottom of the discharge pipe is provided with a discharge port, and the discharge port and the drain outlet are positioned directly opposite each other.

[0008] This utility model has the following beneficial effects:

[0009] This utility model provides a ladle sand-filling device for the tapping position of a converter, mainly composed of a motor, a drive drum, a connecting wire rope, a discharge pipe, a discharge port, and a horn-shaped discharge port. By setting a drive motor on the outside of the ladle, the motor drives the wire rope, causing the discharge pipe, which is located on the top side of the ladle's drain outlet, to shift. After personnel add sand to the horn-shaped discharge port, the sand is discharged through the discharge pipe and the discharge port, thus achieving rapid, accurate, and efficient addition of sand to the ladle. This effectively avoids unnecessary waste of sand and greatly improves the overall production efficiency of the steelmaking converter. It solves the problem that the current method of manually adding sand to the ladle's drain outlet is time-consuming, labor-intensive, and has low accuracy. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1 As shown, a ladle sand guiding and filling device for a converter tapping position includes a motor 1 installed on the outside of the ladle 8. The motor 1 is connected to a winch drum 2, which is connected to a horn-shaped discharge port 5 at the top of the ladle 8 via a wire rope 3. The horn-shaped discharge port 5 is connected to a discharge pipe 6, and the discharge pipe 6 and the drain outlet 9 of the ladle 8 are directly opposite each other.

[0015] A transition roller 4 is provided on the outer side of the ladle 8, and the wire rope 3 and the transition roller 4 are arranged around it.

[0016] The bottom of the discharge pipe 6 is provided with a discharge port 7, and the discharge port 7 and the drain outlet 9 are directly opposite each other.

[0017] In practical application, the various components of this device are pre-assembled. Then, the motor 1 drives the reducer to drive the winch drum 2. The material drop pipe 6 is designed and manufactured as a long-necked funnel shape. The winch drum 2 drives the transition drum 4 and the wire rope 3, ultimately causing the material drop pipe 6 to move up and down. Before the ladle 8 is filled with molten steel, the winch drum 2, driven by the wire rope 3, lifts the long-necked material drop pipe 6 and accurately places it into the ladle 8, ensuring that the lower end of the material drop pipe 6 is aligned with the outlet 9. Then, the operator places the diverting sand on the upper part of the funnel-shaped discharge port 5 of the material drop pipe 6, allowing it to flow into the outlet 9. This reduces the waste of diverting sand and ensures accurate placement, effectively solving the problem that manually adding diverting sand to the outlet 9 of the ladle 8 is time-consuming, labor-intensive, and inaccurate. Therefore, this device has good practicality.
