Description

Technical Field

[0001] This application belongs to the technical field of metal smelting equipment, specifically relating to a casting wire feeder. Background Technology

[0002] In-furnace refining is a crucial step in the steelmaking process. During refining, alloying elements are typically added to the molten metal to improve its properties, processing performance, corrosion resistance, or to achieve specific physical characteristics. Traditionally, alloys are added directly to the molten metal, a simple and straightforward method. However, this process takes a long time to melt, and heavier alloys tend to settle to the bottom while lighter alloys float on top, resulting in low absorption rates and negatively impacting the final smelting outcome. Utility Model Content

[0003] The technical problem to be solved by this application is that the traditional alloy addition method results in a low absorption rate of the molten metal to the alloy, leading to poor melting effect. In order to solve this technical problem, a casting wire feeder is provided that can realize the addition of alloy and improve the absorption rate of alloy.

[0004] The technical solution proposed in this application is as follows:

[0005] A casting wire feeder, comprising:

[0006] frame;

[0007] An unwinding assembly, disposed on the frame, is used to release the core wire;

[0008] The conveying assembly is mounted on the frame;

[0009] A wire feeding tube is provided in the conveying assembly, which is capable of feeding the core wire into the wire feeding tube so that the core wire is conveyed along the wire feeding tube;

[0010] The conveying assembly conveys the core wire at a speed of 0.1-0.8 m / s.

[0011] Using the aforementioned casting wire feeder, the unwinding assembly releases the core wire prepared with alloys or additives, and the conveying assembly transports the core wire at a speed of 0.1-0.8 m / s. The core wire is then conveyed along the feeding tube into the molten metal, thus achieving the addition of alloys or additives. This ensures both the efficiency of alloy or additive addition and a high absorption rate of alloys or additives by the molten metal, improving the smelting effect.

[0012] Furthermore, the conveying assembly includes a mounting box, a conveying module, and a counting module. The mounting box is disposed on the frame, and both the conveying module and the counting module are disposed on the mounting box. The conveying module is used to convey the core wire, and the counting module is used to measure the conveying length of the core wire.

[0013] Furthermore, the conveying assembly also includes a lifting module, which is rotatably connected to the mounting box and located downstream of the conveying module. The wire feeding pipe is connected to the lifting module, and the lifting module has a feeding channel through which the core wire passes. The feed end of the wire feeding pipe is connected to the feeding channel. During the rotation of the lifting module, it can pass through the feeding position and the lifting position.

[0014] When the lifting module is located at the feeding position, the extending direction of the feeding channel is the same as the extending direction of the core wire at the conveying module; when the lifting module is located at the lifting position, the extending direction of the feeding channel is at an angle to the extending direction of the core wire at the conveying module.

[0015] Furthermore, the conveying assembly is rotatable about a first axis, and the feeding tube is rotatable about a second axis parallel to the first axis, and both the conveying assembly and the feeding tube can pass through the working position during their rotation.

[0016] When both the conveying assembly and the feeding tube are in the working position, the core wire in the conveying assembly extends along a first direction, the feeding tube is located downstream of the conveying assembly along the first direction, and the discharge end of the conveying assembly is connected to the inlet end of the feeding tube.

[0017] Furthermore, the rotation radius of the feed tube is 0.2-0.4m.

[0018] Furthermore, the conveying assembly and the wire feeding tube rotate between the working position and the storage position;

[0019] When both the conveying assembly and the feeding tube are in the storage position, the core wire in the conveying assembly extends along a second direction at an angle to the first direction, and the plane containing the central axis of the feeding tube is set at an angle to the second direction.

[0020] Furthermore, the conveying assembly and the wire feeding tube rotate in the same direction from the working position to the storage position.

[0021] Furthermore, the conveying assembly can also secure the core wire.

[0022] Furthermore, the feed tube includes a feeding section, an intermediate section, and a discharge section connected in sequence, and the feeding section is rotatably connected to the conveying assembly around the second axis;

[0023] When both the conveying assembly and the feed pipe are in the working position, the feeding section extends along the first direction.

[0024] Furthermore, the unwinding assembly includes an unwinding shaft, which is rotatably mounted on the frame about a fourth axis, and the unwinding shaft and the conveying assembly are arranged along a first direction perpendicular to the fourth axis; the unwinding shaft can release the core wire during rotation.

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] This application provides a casting wire feeder that can feed alloys or specific additives through core wire during the metal smelting process, thereby improving the absorption rate of the added substances and thus improving the smelting effect.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the casting wire feeder 10 includes a frame 100, an unwinding assembly 200, a conveying assembly 300, and a wire feeding tube 400.

[0038] Both the unwinding assembly 200 and the conveying assembly 300 are mounted on the frame 100. The unwinding assembly 200 is used to release the core wire 20, and the conveying assembly 300 is used to convey the core wire 20. A feed pipe 400 is mounted on the conveying assembly 300 so that the conveying assembly 300 feeds the core wire 20 into the feed pipe 400 and conveys it along the feed pipe 400. It is understood that the other end of the feed pipe 400 can extend above the molten metal, thereby feeding the core wire 20 into the molten metal, for example, into molten steel. The conveying assembly 300 conveys the core wire 20 at a speed of 0.1-0.8 m / s to ensure efficient conveying of the core wire 20 while accurately controlling the feed rate.

[0039] Using the aforementioned casting wire feeder 10, the unwinding assembly 200 releases the core wire 20 prepared with alloys or additives, and the conveying assembly 300 conveys the core wire 20 at a speed of 0.1-0.8 m / s. The core wire 20 is then conveyed along the feeding tube 400 into the molten metal, thus achieving the addition of alloys or additives. This ensures both the efficiency of alloy or additive addition and a high absorption rate of alloys or additives by the molten metal, improving the smelting effect.

[0040] It should be explained that feeding the core wire 20 at a speed of 0.1-0.8 m / s allows for sufficient contact and reaction between the core wire 20 and the molten metal, thereby increasing the absorption rate of alloys or additives by the molten metal. Furthermore, designing the outer diameter of the core wire to be 9-16 mm and the metal sheath thickness to be 0.4-0.6 mm, combined with a feeding speed of 0.1-0.8 m / s, can further improve the efficiency of alloy or additive addition and also result in a higher absorption rate of alloys or additives by the molten metal, thus improving the melting effect. For example, feeding at a speed of 0.5 m / s, with a core wire diameter of 13 mm and a metal sheath thickness of 0.45 mm, yields excellent melting results.

[0041] In one embodiment, the casting wire feeder 10 further includes a roller assembly 110 disposed at the bottom of the frame 100 to enable the casting wire feeder 10 to move, further facilitating the transportation of the casting wire feeder 10. Preferably, the roller assembly 110 includes a plurality of casters.

[0042] In one embodiment, the conveying assembly 300 is rotatable about a first axis, and the feeding tube 400 is rotatable about a second axis parallel to the first axis, and both the conveying assembly 300 and the feeding tube 400 can pass through the working position during their rotation.

[0043] When both the conveying assembly 300 and the feeding pipe 400 are in the working position, the core wire 20 in the conveying assembly 300 extends along a first direction, and the feeding pipe 400 is located downstream of the conveying assembly 300 along the first direction. The discharge end of the conveying assembly 300 is connected to the inlet end of the feeding pipe 400, so that the conveying assembly 300 can input the core wire 20 into the feeding pipe 400 and convey it along the feeding pipe 400. Specifically... Figure 1 In the embodiment shown, both the first axis and the second axis are vertical axes, and the first direction is horizontal.

[0044] It should be explained that when both the conveying assembly 300 and the wire feeding tube 400 are in the working position, the wire feeding tube 400 is located downstream of the conveying assembly 300 in the first direction. That is, the conveying assembly 300 and the wire feeding tube 400 are arranged sequentially along the first direction, and the wire feeding tube 400 is located downstream of the conveying assembly 300 along the conveying direction of the core wire 20, so that the conveying assembly 300 can input the core wire 20 into the wire feeding tube 400.

[0045] Combination Figure 1 It should be noted that, Figure 1When the casting wire feeder 10 is in operation, the conveying assembly 300 and the wire feeding tube 400 are in the working position. The unwinding assembly 200 releases the core wire 20 to the conveying assembly 300, which then feeds the core wire 20 into the wire feeding tube 400, where it is guided into the molten steel. After the core wire 20 is fed in, the conveying assembly 300 and the wire feeding tube 400 can be rotated to angle them, reducing the length of the conveying assembly 300 and the wire feeding tube 400 extending out of the frame 100 and thus reducing the size of the casting wire feeder 10, making it easier to transport and store.

[0046] In one embodiment, both the conveying component 300 and the feeding tube 400 can pass through the storage position during rotation, and the conveying component 300 and the feeding tube 400 rotate between the working position and the storage position. For example... Figure 2 As shown, at this time, both the conveying component 300 and the feeding tube 400 are in the storage position.

[0047] When both the conveying assembly 300 and the wire feeding tube 400 are in the retracted position, the core wire 20 in the conveying assembly 300 extends along a second direction at an angle to the first direction, and the plane containing the central axis of the wire feeding tube 400 is angled to the second direction. By simultaneously retracting the conveying assembly 300 and the wire feeding tube 400, the volume of the casting wire feeder 10 can be further reduced, thereby facilitating the transportation and storage of the casting wire feeder 10. Specifically... Figure 2 In the embodiment shown, the first direction and the second direction are perpendicular, and both the first direction and the second direction are horizontal. The plane containing the central axis of the feed tube 400 is perpendicular to the second direction.

[0048] It is understandable that, such as Figure 1 and Figure 2 As shown, the extension range of the conveying assembly 300 beyond the frame 100 is relatively small. Therefore, in other embodiments, the conveying assembly 300 can also be fixedly mounted on the frame 100, and the feeding tube 400 can be retracted by rotating it. Of course, the conveying assembly 300 is preferably rotatable, and the following description uses the rotatable conveying assembly 300 as an example.

[0049] Combination Figure 1 and Figure 2 It can be determined that the conveying assembly 300 and the wire feeding tube 400 rotate in the same direction from the working position to the storage position to improve the storage effect. Assuming that when viewed from above the casting wire feeder 10, the conveying assembly 300 rotates clockwise from the working position to the storage position, and the wire feeding tube 400 also rotates clockwise from the working position to the storage position.

[0050] It should be noted that the above-mentioned working position and storage position are described based on function, and do not limit the conveying component 300 and the wire feeding tube 400 to be in the same position. Rather, it means that when in the working position, the conveying component 300 and / or the wire feeding tube 400 can convey the core wire 20; when in the storage position, the conveying component 300 and / or the wire feeding tube 400 retract to the frame 100. In other words, the conveying component 300 rotates between the first working position and the first storage position, and the wire feeding tube 400 rotates between the second working position and the second storage position.

[0051] In one embodiment, the casting wire feeder 10 further includes a first rotary drive 510, which is disposed on the frame 100 and connected to the conveying assembly 300 to drive the conveying assembly 300 to rotate around a first axis. Specifically, the first rotary drive 510 is a motor.

[0052] In one embodiment, the conveying assembly 300 can also fix the core wire 20, i.e., stop the conveying of the core wire 20, so that the core wire 20 is fixed relative to the frame 100. After the core wire 20 is fixed, the feeding tube 400 can be rotated about the second axis, causing the core wire 20 to move telescope within the feeding tube 400, thereby removing the metal slag at the discharge end of the feeding tube 400. It should be explained that the discharge end of the feeding tube 400 is close to the molten steel, and the molten steel can easily splash onto the discharge end of the feeding tube 400 and solidify to form metal slag. If too much metal slag accumulates, it can cause the feeding tube 400 to become blocked. Therefore, the telescoping movement of the core wire 20 within the feeding tube 400 causes the end of the core wire 20 closest to the molten steel to repeatedly enter and exit the feeding tube 400, thereby removing the metal slag at the discharge end of the feeding tube 400.

[0053] In one embodiment, the conveying assembly 300 includes a mounting housing 310, a conveying module 320, and a counting module 330. The mounting housing 310 is rotatably connected to the frame 100 about a first axis, and both the conveying module 320 and the counting module 330 are disposed in the mounting housing 310. The conveying module 320 is used to convey the core wire 20, and the counting module 330 is used to measure the conveying length of the core wire 20. It can be determined that when the conveying assembly 300 is in the working position, the conveying module 320 and the counting module 330 are arranged along a first direction to ensure that the core wire 20 in the conveying assembly 300 extends along the first direction. Specifically... Figure 3 In the illustrated embodiment, the counting module 330 is located downstream of the conveying module 320.

[0054] In one embodiment, the conveying module 320 includes a conveying drive wheel 321, a conveying driven wheel 322, and a conveying drive component 323. Both the conveying drive wheel 321 and the conveying driven wheel 322 are rotatably disposed within the mounting box 310, and can cooperate to clamp the core wire 20. The conveying drive component 323 is disposed in the mounting box 310 and connected to the conveying drive wheel 321 to drive the conveying drive wheel 321 to rotate, thereby enabling the conveying drive wheel 321 and the conveying driven wheel 322 to cooperate in conveying the core wire 20.

[0055] Furthermore, the conveying module 320 also includes a clamping drive 324, which is disposed within the mounting housing 310 and connected to the conveying driven wheel 322 to drive the conveying driven wheel 322 to clamp the core wire 20 against the conveying drive wheel 321. It is understood that the conveying driven wheel 322 is rotatably connected to the clamping drive 324. Optionally, the clamping drive 324 is a pneumatic cylinder or a hydraulic cylinder.

[0056] In practical applications, the circumferential sides of the conveying drive wheel 321 and the conveying driven wheel 322 are concave arc-shaped surfaces, and multiple anti-slip teeth are arranged at intervals along the circumference on the arc-shaped surfaces. This prevents the core wire 20 from slipping relative to the conveying module 320. Simultaneously, it can be determined that when the conveying drive unit 323 stops driving the conveying drive wheel 321 to rotate, the conveying drive wheel 321 and the conveying driven wheel 322 can cooperate to clamp and fix the core wire 20.

[0057] Specifically Figure 3 In the illustrated embodiment, the conveying module 320 includes two corresponding conveying drive wheels 321, two conveying driven wheels 322, and two cylinders. The two conveying drive wheels 321 are arranged sequentially at intervals along the conveying direction of the core wire 20, and the conveying drive component 323 is connected to both conveying drive wheels 321. Thus, the cooperation of the two conveying drive wheels 321 and the two conveying driven wheels 322 can further improve the stability of the conveying process.

[0058] In one embodiment, the counting module 330 includes a counting wheel 331, an auxiliary wheel 332, and an encoder 333. Both the counting wheel 331 and the auxiliary wheel 332 are rotatably mounted within the mounting box 310, and they cooperate to clamp the core wire 20, allowing it to rotate during core wire 20 transport. The encoder 333 is mounted on the counting wheel 331 to measure the transport length of the core wire 20 during the rotation of the counting wheel 331. It should be noted that, to prevent the core wire 20 from slipping relative to the counting wheel 331 and the auxiliary wheel 332, the circumferential sides of the counting wheel 331 and the auxiliary wheel 332 are also designed as concave arc-shaped surfaces, and anti-slip teeth are also provided on these arc-shaped surfaces.

[0059] In practical applications, the counting module 330 also includes a compression spring 334, which is located inside the mounting box 310 and connected to the counting wheel 331 to drive the counting wheel 331 to move toward the auxiliary wheel 332, thereby pressing the core wire 20 against the auxiliary wheel 332.

[0060] In one embodiment, both sides of the mounting box 310 are provided with through holes for the core wire 20 to pass through in the conveying direction of the core wire 20. Specifically... Figure 3 In the middle, the core wire 20 enters the mounting box 310 through the left through hole, then passes through the conveying module 320 and the counting module 330 in sequence, and then exits through the right through hole.

[0061] Please see Figure 3 and Figure 4 In one embodiment, the conveying assembly 300 further includes a lifting module 340, which is rotatably connected to the mounting housing 310 about a third axis and located downstream of the conveying module 320. A feed tube 400 is rotatably connected to the lifting module 340 about a second axis. The lifting module 340 has a feeding channel through which the core wire 20 passes, and during rotation, the lifting module 340 can pass through both the feeding position and the lifting position. Figure 4 As shown, at this time, both the conveying component 300 and the feeding pipe 400 are in the working position, and the lifting module 340 is in the lifting position. Similarly, it can be seen that, specifically... Figure 1 and Figure 2 In the embodiment shown, the lifting module 340 is located at the feeding position.

[0062] When the lifting module 340 is in the feeding position and the conveying assembly 300 is in the working position, the feeding channel extends along the first direction, that is, the extension direction of the feeding channel is the same as the extension direction of the core wire 20 at the conveying module 320, so that the core wire 20 conveyed by the conveying module 320 can pass through the feeding channel. When the lifting module 340 is in the lifting position, the extension direction of the feeding channel is set at an angle to the extension direction of the core wire 20 at the conveying module 320, so that the path of the core wire 20 is extended. When the feeding tube 400 is in the working position, the feeding channel is connected to the feed end of the feeding tube 400, so that the core wire 20 passing through the feeding channel enters the feeding tube 400, facilitating the conveying of the core wire 20.

[0063] The third axis is perpendicular to the extension direction of the core wire 20 inside the mounting box 310. Specifically, the third axis is also perpendicular to the first axis.

[0064] Understandably, when the lifting module 340 needs to be rotated from the feeding position to the lifting position, the conveying module 320 needs to stop conveying the core wire 20, that is, clamp and fix the core wire 20. By reciprocating between the feeding position and the lifting position, the core wire 20 can be moved telescopically within the feeding tube 400, removing the metal slag at the discharge end of the feeding tube 400.

[0065] It should be noted that the reciprocating lifting and lowering of the core wire 20 near the molten steel end is achieved by rotating the lifting module 340. This operation can be coordinated with the rotation of the feeding tube 400 in the above embodiment to extend the travel of the core wire 20. Of course, in other embodiments, the rotation of the feeding tube 400 can also be used to switch between its working position and its storage position. The removal of metal slag at the discharge end of the feeding tube 400 can be achieved by the action of the lifting module 340.

[0066] Please see Figures 3 to 5 In one embodiment, the lifting module 340 includes a mounting plate 341 and a guide tube 342. The mounting plate 341 is rotatably connected to the side of the mounting box 310 away from the unwinding assembly 200 about a third axis. The guide tube 342 is disposed on the mounting plate 341, and the feed tube 400 is rotatably connected to the mounting plate 341 about a second axis. The guide tube 342 has the aforementioned feeding channel. When the lifting module 340 is in the feeding position, the guide tube 342 is coaxial with the through hole on the mounting box 310, so that the core wire 20 output from the through hole enters the guide tube 342.

[0067] Furthermore, the conveying assembly 300 also includes a lifting drive 350, which is disposed in the mounting box 310 and connected to the mounting plate 341 to drive the mounting plate 341 to rotate about a third axis. Specifically... Figure 3 In the embodiment shown, the lifting drive 350 is a cylinder and is located at the bottom of the mounting box 310. The drive end of the lifting drive 350 is hinged to the mounting plate 341.

[0068] Please see Figure 1 In one embodiment, the wire feeding pipe 400 includes a feed section 410, an intermediate section 420, and a discharge section 430 connected in sequence. The feed section 410 is rotatably connected to the conveying assembly 300 about a second axis. When both the conveying assembly 300 and the wire feeding pipe 400 are in the working position, the feed section 410 extends along a first direction and communicates with the guide pipe 342 to receive the core wire 20 output from the guide pipe 342; the discharge section 430 extends vertically to guide the core wire 20 to be conveyed into the molten steel. In practical applications, the intermediate section 420 is arc-shaped to make the conveying of the core wire 20 within the wire feeding pipe 400 smoother.

[0069] As can be seen from the above embodiments, what needs to be explained is that... Figure 4In the illustrated embodiment, the lifting module 340 is in the lifted position, at which time the discharge section 430 of the feeding tube 400 is inclined relative to the vertical direction. However, in actual operation, the lifting module 340 is used to realize the reciprocating movement of the core wire 20 within the feeding tube 400 to remove metal slag at the discharge end. That is, when the lifting module 340 is in the lifted position, the conveying component 300 is in a special state; when the lifting module 340 is in the feeding position, the conveying component 300 is in a normal state. Figure 1 and Figure 2 In the embodiments shown, the conveying components 300 are all in normal condition, and the discharge section 430 extends vertically at this time.

[0070] In one embodiment, the rotation radius of the feed tube 400 is 0.2-0.4m. It is understood that, as... Figure 5 As shown, the feed tube 400 is located in the storage position. The central axis of the feed tube 400 forms a 90° angle with the core wire 20 in the conveying assembly 300. The core wire 20 extends from the conveying assembly 300 to the feed tube 400, and the extension path of the core wire 20 is close to the rotation path of the feed end of the feed tube 400. Therefore, by increasing the rotation radius of the feed tube 400, the curvature of the rotation path at the feed end of the feed tube 400 can be reduced, that is, the curvature of the core wire 20 between the conveying assembly 300 and the feed tube 400 can be reduced, thus reducing the degree of bending of the core wire 20 and preventing it from breaking.

[0071] It should also be noted that the conveying assembly 300 is rotatably connected to the frame 100. During the process of the conveying assembly 300 rotating to the storage position, since the core wire 20 between the unwinding assembly 200 and the conveying assembly 300 is relatively long, the core wire 20 has a large range of motion and can adaptively adjust its curvature, thereby preventing the core wire 20 between the unwinding assembly 200 and the conveying assembly 300 from being broken.

[0072] Please also refer to Figure 6 In one embodiment, the casting wire feeder 10 further includes a second rotary drive 520, which is disposed on the conveying assembly 300 and specifically on the mounting plate 341. The second rotary drive 520 is connected to the wire feeding tube 400 to drive the wire feeding tube 400 to rotate around a second axis.

[0073] Furthermore, the casting wire feeder 10 also includes a connecting block 530, which is rotatably connected to the mounting plate 341 around the second axis. The wire feeding tube 400 is fixedly connected to the connecting block 530, thereby increasing the rotation radius of the wire feeding tube 400.

[0074] Furthermore, the casting wire feeder 10 also includes a connecting gear 540 and a connecting rack 550. The connecting gear 540 is fixedly connected to the connecting block 530, and the connecting rack 550 meshes with the connecting gear 540. The second rotary drive member 520 is connected to the connecting rack 550 to drive the connecting rack 550 to reciprocate, thereby causing the connecting gear 540 and the connecting block 530 to rotate around the second axis.

[0075] It is understood that in this embodiment, the second rotary drive 520 is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. In other embodiments, the second rotary drive 520 may also be a motor, in which case the second rotary drive 520 is directly connected to the connecting block 530 to drive the connecting block 530 to rotate around the second axis.

[0076] Please see Figure 1 In one embodiment, the unwinding assembly 200 includes an unwinding shaft 210, which is rotatably mounted on the frame 100 about a fourth axis perpendicular to the first direction and the first axis, i.e., the fourth axis is the central axis of the unwinding shaft 210. During rotation, the unwinding shaft 210 releases the core wire 20. Releasing the core wire 20 by rotating the unwinding shaft 210 about the fourth axis effectively improves the smoothness of core wire release and prevents the core wire 20 from getting stuck. Specifically, a winding frame 220 is sleeved on the unwinding shaft 210, which is used to wind the core wire 20, and the winding frame 220 is I-shaped.

[0077] Furthermore, the unwinding shaft 210 and the conveying assembly 300 are arranged along the first direction. Thus, when both the conveying assembly 300 and the feed tube 400 are in the working position, the core wire 20 in the conveying assembly 300 is conveyed along the first direction, while the unwinding shaft 210 is located upstream of the conveying assembly 300 along the first direction, so that the core wire 20 is not bent excessively, thereby making the conveying of the core wire 20 smoother.

[0078] In one embodiment, the unwinding assembly 200 further includes an unwinding drive connected to the unwinding shaft 210 to drive the unwinding shaft 210 to rotate, thereby achieving automatic release of the core wire 20. Simultaneously, unwinding via the unwinding drive also allows for tension control of the core wire 20. This prevents the core wire 20 from breaking due to excessive tension and also avoids excessive accumulation of the core wire 20 between the unwinding assembly 200 and the conveying assembly 300.

[0079] To facilitate understanding of the technical solution of this application, this document combines... Figure 1 , Figure 2 and Figure 4 The working process of the casting wire feeder 10 in the above embodiments will be described as follows:

[0080] Initially, the conveying component 300 and the wire feeding tube 400 in the casting wire feeder 10 are both in the storage position, and the core wire 20 on the unwinding component 200 has passed through the conveying component 300 and entered the wire feeding tube 400.

[0081] The casting wire feeder 10 is moved to a preset working position. Then, the first rotary drive 510 and the second rotary drive 520 respectively drive the conveying assembly 300 and the wire feeding tube 400 to rotate to the working position, bringing the discharge end of the wire feeding tube 400 closer to the molten steel. Next, the unwinding drive actuates, releasing the core wire 20 while maintaining a certain tension. Simultaneously, the conveying module 320 continuously feeds the core wire 20 into the wire feeding tube 400, and through the wire feeding tube 400, the core wire 20 is fed into the molten steel. During the core wire 20 conveying process, the counting module 330 measures the conveying length of the core wire 20, thereby obtaining the feeding amount of the core wire 20. After the feeding amount reaches the required level, the unwinding assembly 200 and the conveying assembly 300 stop conveying the core wire 20, and then the first rotary drive 510 and the second rotary drive 520 respectively drive the conveying assembly 300 and the wire feeding tube 400 to the storage position.

[0082] It should be noted that after wire feeding is completed, the lifting module 340 can be driven by the lifting drive component 350 to reciprocate between the feeding position and the lifting position to remove the metal slag at the discharge end of the wire feeding tube 400. In addition, a control box with a display screen can be installed on the frame 100 to input control parameters and control the operation of the casting wire feeder 10.

[0083] In summary, the casting wire feeder 10 provided in this application has at least the following advantages:

[0084] 1. The conveying component 300 and the wire feeding tube 400 can be stored, which can effectively reduce the volume of the casting wire feeder 10, thereby facilitating the transportation, use and storage of the casting wire feeder 10;

[0085] 2. By actively unwinding the core wire 20 in conjunction with the unwinding drive and the unwinding shaft 210, the core wire 20 can be conveyed with stable tension.

[0086] 3. Using an I-shaped winding frame 220 to rotate around the fourth axis to release the core wire 20 can make the release of the core wire 20 smoother and avoid jamming;

[0087] 4. The large rotation radius of the feed tube 400 can prevent the core wire 20 from being broken during the rotation of the feed tube 400.
