Description

Technical Field

[0001] This utility model relates to a device for the stable use of aluminum wire in LF furnace steelmaking, and to a device for placing metal wires during the steelmaking process. Background Technology

[0002] In the converter steelmaking process, the required aluminum content in the molten steel varies depending on the type of steel being produced. To precisely control the aluminum content, aluminum wire is often fed into the molten steel via a wire feeder at key points after the converter or on the refining platform of the refining furnace. In practice, the purchased coiled aluminum wire is usually equipped with aluminum wire supports. However, these supports present several challenging problems.

[0003] The specifications of aluminum wire frames on the market are extremely diverse, with no unified standard whatsoever. This makes weight estimation extremely difficult, as it is impossible to accurately predict the weight of each frame. Secondly, once coiled aluminum wire is fixed in a frame, it cannot be adjusted when it folds during use; the only solution is to cut it, which greatly reduces the utilization rate of the aluminum wire.

[0004] Therefore, it is necessary to provide a new device that can effectively improve the utilization rate of coiled aluminum wire. Utility Model Content

[0005] This invention provides a device for the stable use of aluminum wire in LF furnace steelmaking, which effectively improves the utilization rate of coiled aluminum wire.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A device for the stable use of aluminum wire in LF furnace steelmaking includes a square frame, the internal volume of which is designed based on the weight of the aluminum wire to be fed in, forming a chamber for placing coiled aluminum wire.

[0008] Two symmetrically distributed frame doors are installed on the top of a square frame. One side of each frame door is rotatably connected to the side of the square frame. With the top surface of the square frame as the reference surface, if one frame door rotates counterclockwise and the other frame door rotates clockwise, both frame doors are open. If one frame door rotates clockwise and the other frame door rotates counterclockwise, both frame doors are closed.

[0009] The other side of the frame door is a trapezoidal door frame, and the long side of the trapezoidal door frame is not set. When both frame doors are closed at the same time, an unclosed opening is formed at the top center of the square frame.

[0010] A baffle is installed at the middle position of the two sides of the square frame that are not connected to the frame door. The baffle is long and can be rotatably installed on the square frame by bolts. When the long side of the baffle coincides with the side of the square frame, the two ends of the baffle are pressed onto the frame door.

[0011] Furthermore, the frame door includes a rectangular door frame, with its two short sides extending outwards to form extension ends. One end of a connecting rod is fixed to the end of each of the two extension ends, and the other end of the connecting rod is fixed to an adjacent long side of the rectangular door frame. The distance between the fixing point of the other end of the connecting rod and the matching extension end is one-third of the length of the long side of the rectangular door frame.

[0012] Furthermore, the other long side of the rectangular door frame is connected to the side of the square frame via a rotating structure, and two rotating structures are provided.

[0013] The rotating structure includes two hollow tubes, defined as the first hollow tube and the second hollow tube respectively. The first hollow tube is fixed on the other long side of the rectangular door frame, and the second hollow tube is fixed on the side of the square frame. The rotating rod passes through the first hollow tube and the second hollow tube in sequence.

[0014] Furthermore, a spiral hole is made in the center of the baffle, and a fixing hole is made in the middle of the two sides of the four-sided frame that are not connected to the frame door. Bolts are screwed into the spiral hole and the fixing hole in sequence, perpendicular to the direction of the baffle.

[0015] The bottom surface of the baffle is located on the surface of the frame door in a direction parallel to the top of the square frame.

[0016] By using the above technical solutions, compared with the prior art, this utility model has the following beneficial effects:

[0017] The device provided by this utility model for the stable use of aluminum wire in LF furnace steelmaking can promptly handle abnormalities in the fed aluminum wire, avoiding cutting operations and improving the utilization rate of aluminum wire. At the same time, the device can be reused, saving costs. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of this application, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the scope of protection of the present invention.

[0023] As described in the background section, aluminum wire needs to be fed into molten steel at critical points in the refining platform of the furnace or refining furnace. Currently, coiled aluminum wire placed next to the LF furnace is usually fixed in place with a fixed frame. An opening is made at the top of the fixed frame to pull out the aluminum wire. Therefore, if the aluminum wire kinks during feeding, the operator cannot adjust the coiled aluminum wire. Therefore, if... Figure 1 As shown, this utility model provides a device for the stable use of aluminum wire in LF furnace steelmaking. It can handle abnormalities in a timely manner, avoiding the need to directly cut the aluminum wire, thereby improving the utilization rate of the aluminum wire.

[0024] Specifically, it includes a square frame 1, the internal volume of which is designed based on the weight of the aluminum wire to be fed in, forming a chamber for placing the coiled aluminum wire 0; two symmetrically distributed frame doors 2 are installed on the top of the square frame, one side of which is rotatably connected to the side of the square frame. With the top surface of the square frame as the reference plane, if one frame door rotates counterclockwise and the other frame door rotates clockwise, both frame doors are open; if one frame door rotates clockwise and the other frame door rotates counterclockwise, both frame doors are closed; the other side of the frame door is a trapezoidal door frame, and the long side of the trapezoidal door frame is not provided. When both frame doors are closed at the same time, an unclosed opening is formed at the center of the top of the square frame.

[0025] by Figure 1Taking the frame door on the left side as an example, the frame door includes a rectangular door frame (the "eye" shaped frame in the figure), whose two short sides extend outward (to the right) to form extension ends. The ends of the two extension ends are respectively fixed to one end of the connecting rod 3, and the other end of the connecting rod is fixed to an adjacent long side of the rectangular door frame, that is, the connecting rod and the rectangular door frame form a triangle; in order to maintain the stability of the structure, the distance between the fixing point of the other end of the connecting rod and the matching extension end is one-third of the length of the long side of the rectangular door frame.

[0026] Therefore, from Figure 1 It's clearly visible that the right side of the frame door forms an unsealed trapezoidal structure. When the two frame doors are closed, a suitable unsealed opening is created in the middle. The size of this opening is sufficient to secure the coiled aluminum wire and also allows for adjustment if problems arise with the wire. If the unsealed opening still cannot meet the adjustment requirements, simply opening the frame door will suffice. Figure 1 Taking a perspective as an example, the frame door on the left rotates counterclockwise, while the frame door on the right rotates clockwise to open.

[0027] Regarding the opening and closing of the frame door, the preferred structure provided in this application is that the other long side of the rectangular door frame is connected to the side of the square frame via a rotating structure. Considering cost and opening / closing functionality, two rotating structures are provided. Each rotating structure includes two hollow tubes, defined as a first hollow tube 4 and a second hollow tube 5. The first hollow tube is fixed to the other long side of the rectangular door frame, and the second hollow tube is fixed to the side of the square frame. A rotating rod 6 passes sequentially through the first and second hollow tubes. This design is the simplest and most reliable. Figure 1 The frame door is pulled up from the top of the viewpoint, and the rotating rod rotates within the connecting cavity formed by the first and second hollow tubes, thus pulling the frame door up.

[0028] In the actual smelting process, in order to ensure the stability of the coiled aluminum wire, the frame door of the square frame is equipped with a baffle 7 for locking. The baffle is long and narrow and can be rotatably installed on the square frame by bolts 8. When the long side of the baffle coincides with the side of the square frame, the two ends of the baffle are pressed against the frame door.

[0029] The specific structure is as follows: Figure 2 As shown, a spiral hole is made at the center of the baffle, and fixing holes are made at the middle of the two sides of the square frame that are not connected to the frame door. Figure 1From the perspective of the two square frames (the upper and lower sides), the bolts are screwed into the spiral holes and fixing holes in sequence, perpendicular to the baffle. The baffle can rotate around the bolt. To ensure the locking mechanism is feasible, the bottom surface of the baffle is higher than the surface of the frame door in the direction parallel to the top of the square frame. When the frame door needs to be opened, simply rotate the baffle so that its two ends are not above the frame door. If the two ends of the baffle are exactly on the triangular part of the frame door, the frame door is locked.

[0030] The above design ensures that the provided device can be reused, thereby saving costs. The opening and closing of the frame door allows for the handling of abnormal aluminum wire feeding, preventing wire cutting and improving wire utilization.
