Technical Field
[0001] This utility model relates to the field of magnesium alloy production technology, and in particular to an electromagnetic alloy melting furnace. Background Technology
[0002] Electromagnetic alloy melting is an advanced materials preparation technology that primarily utilizes electromagnetic induction heating and electromagnetic stirring to melt alloys. This technology effectively improves the purity and homogeneity of alloys, reduces the influence of impurity elements, and thus yields high-quality alloy materials.
[0003] The electromagnetic alloy melting furnace mainly consists of a furnace body, induction coil, and intermediate frequency power supply. The furnace body is made entirely of stainless steel, which is aesthetically pleasing and durable. The induction coil is wound with rectangular copper tubes and coated with insulating paint. The intermediate frequency power supply uses IGBT modules, which have high heating efficiency.
[0004] In the production of magnesium alloys, the raw materials need to be placed in an electric melting furnace for heating and melting. After the materials are completely melted, the alloy solution in the electric melting furnace is poured into a mold. After cooling, the alloy ingot is removed from the mold to complete the production of the alloy ingot. This production process requires pouring the molten alloy from the electric melting furnace into the mold, which is not easy to operate. Therefore, an electromagnetic alloy melting furnace is proposed to solve the above problems. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figures 1 to 3 This utility model provides an embodiment of an electromagnetic alloy melting furnace, comprising a base plate 1. The top of the base plate 1 has a channel for water flow to facilitate condensation. It is made of a high-strength, high-temperature-resistant special metal material to ensure stable support of the entire equipment during the melting process. A support frame 2 is fixedly connected to the top of the base plate 1, which is used to fix the position of the drive structure and has sufficient load-bearing capacity and stability. A melting mechanism 3 is installed on the inner wall of the support frame 2, which can perform melting and firing operations. A demolding mechanism 4 is slidably connected to the inner wall of the base plate 1, which assists the operator in quickly and completely removing the formed alloy product from the mold 401.
[0041] Specifically, this electromagnetic alloy melting furnace consists of a base plate 1, a support frame 2, a melting mechanism 3, and a demolding mechanism 4. The base plate 1 is made of a special metal and has a water channel on top to aid in condensation. The support frame 2 is fixed to the top of the base plate 1 to stabilize the drive structure. The melting mechanism 3 is located on the inner wall of the support frame 2 and is used for melting and firing. The demolding mechanism 4 is located on the inner wall of the base plate 1 and assists in rapid and complete demolding.
[0042] The melting mechanism 3 includes a melting box 301. A drive assembly 302 is fixedly connected to the outside of the melting box 301. The drive assembly 302 includes a rotary motor 3021, which is externally mounted on the top of the base plate 1. When the rotary motor 3021 is started, the base plate 1 provides a fixed mounting position for the rotary motor 3021. A rotating shaft 3022 is fixedly connected to the drive end of the rotary motor 3021. Rotation of the drive end of the rotary motor 3021 drives the rotating shaft 3022 to rotate. The rotating shaft 3022 is externally rotatably connected to the inner wall of the support frame 2, which provides a fixed position for the rotating shaft 3022.
[0043] Specifically, the melting box 301 of the melting mechanism 3 is externally connected to the drive assembly 302, and its rotating motor 3021 is mounted on the top of the base plate 1. The base plate 1 has a fixing effect on the motor. The motor drive end is connected to the rotating shaft 3022. The motor drives the shaft to rotate, and the rotating shaft 3022 is rotatably connected to the inner wall of the support frame 2. The support frame 2 has a fixing effect on the rotating shaft 3022.
[0044] The drive assembly 302 is externally rotatably connected to the inner wall of the support frame 2. A heating layer 306 is installed on the inner wall of the melting box 301 to heat the raw materials. A cooling layer 305 is installed outside the heating layer 306 to prevent the temperature of the heating layer 306 from becoming too high and damaging the melting box 301. A crucible 303 is fixedly connected to the top of the heating layer 306, serving as the place where the raw materials are placed. A gate 304 is fixedly connected to the outside of the crucible 303 to guide the outflow of the liquid finished product. A rotating shaft 3022 is externally fixedly connected to the outside of the melting box 301. The rotation of the rotating shaft 3022 causes the melting box 301 to change position, allowing it to tilt and facilitate the outflow of the liquid finished product. A condensate pipe 307 is installed outside the cooling layer 305 to guide the flow of condensate.
[0045] Specifically, the drive assembly 302 is rotatably connected to the inner wall of the support frame 2. The inner wall of the melting box 301 has a heating layer 306 to heat the raw materials, and an outer cooling layer 305 to prevent damage to the box body. The crucible 303 is fixed to the top of the heating layer 306 and holds the raw materials, with its pouring port 304 guiding the liquid finished product to flow out. The rotating shaft 3022 is connected to the melting box 301, causing the box body to tilt to facilitate the flow of liquid. A condensate pipe 307 outside the cooling layer 305 guides the flow of condensate.
[0046] Reference Figure 3 and Figure 4 The ejection mechanism 4 includes a mold 401, which is externally slidably connected to the top of the base plate 1, allowing for mold 401 to be replaced by sliding. A cylinder 402 is mounted on the inner wall of the mold 401. A moving plate 403 is fixedly connected to the drive end of the cylinder 402. Activating the cylinder 402 causes a positional change in the driving end, which in turn moves the moving plate 403, providing the external driving force for two ejections. A fixed plate 404 is fixedly connected to the bottom of the moving plate 403, and a positional change in the moving plate 403 causes a positional change in the fixed plate 404. Two moving blocks 409 are rotatably connected inside the moving plate 403, and a positional change in the moving plate 403 causes the two moving blocks 409 to move upwards.
[0047] Specifically, the ejection mechanism 4 consists of a mold 401, which is slidably connected to the top of the base plate 1 for easy replacement. A cylinder 402 is installed on the inner wall of the mold 401, and its drive end is connected to a moving plate 403, which can move the position of the moving plate 403. The cylinder 402 provides the external power for the two ejections. The bottom of the moving plate 403 is connected to a fixed plate 404, which can move the plate's position. Two moving blocks 409 are rotatably connected internally, and when the plate moves, it causes the two moving blocks 409 to move upwards.
[0048] The fixed plate 404 has two fixedly connected positioning shafts 410 inside. Changes in the position of the fixed plate 404 cause the two positioning shafts 410 to change position accordingly. The fixed plate 404 also has multiple fixed shafts 406 inside. Changes in the position of the fixed plate 404 cause changes in the position of the multiple fixed shafts 406. The inner wall of the movable plate 403 has multiple ejector shafts 405 fixedly connected. Changes in the position of the movable plate 403 cause changes in the position of the multiple ejector shafts 405. The inner wall of the mold 401 has a fixed block 407 fixedly connected, and the inner wall of the fixed block 407 has a fixed irregular block 412 fixedly connected. The mold 401 fixes the position of the fixed block 407, and the fixed block 407 fixes the position of the irregular block 412. Maintaining the unchanged positions of both affects the changing structure.
[0049] Specifically, the positioning shaft 410 and the fixed shaft 406 are connected inside the fixed plate 404. The change of its position causes the two to move. When the position of the moving plate 403 changes, it will also cause the ejection shaft 405 to move. The mold 401, the fixed block 407 and the irregular block 412 are fixed to each other, and the changing structure is affected by contact.
[0050] A top plate 408 is fixedly connected to the top of multiple fixed shafts 406. The positional movement of the fixed shafts 406 causes the top plate 408 to move, thus achieving a single ejection of the finished product. The exteriors of two movable blocks 409 contact the exterior of the irregularly shaped block 412. During movement, the movable blocks 409 contacting the exterior of the irregularly shaped block 412 changes their direction of movement, causing them to stop. Two springs 411 are fixedly connected to the exterior of the two movable blocks 409. The movable blocks 409 cause the springs 411 to deform. After the external force is removed, the springs 411 return to their original position, causing the movable blocks 409 to reset.
[0051] Specifically, the positional changes of multiple fixed shafts 406 cause the top plate 408 to move, thus ejecting the finished product in one go. The two moving blocks 409 rise and come into contact with the outside of the irregular block 412. When they touch, the moving blocks 409 change their moving direction and stop moving. When the two moving blocks 409 come into contact with the outside of the irregular block 412 and move away from each other, the spring 411 will deform. After the external force is removed, the spring 411 resets and drives the moving blocks 409 to reset.
[0052] Working principle: Electromagnetic powder is placed inside crucible 303, and then heating layer 306 is activated to heat it. Cooling layer 305 provides external protection, and condensate pipe 307 can pump cold water to cool the outside, preventing the inner wall of melting box 301 from being damaged due to excessive temperature. When the appropriate temperature is reached, rotating motor 3021 is activated, which drives rotating shaft 3022 to rotate. The rotation of rotating shaft 3022 drives melting box 301 to rotate, causing the liquid inside crucible 303 to flow out from the inner wall of gate 304 at an angle. This electric furnace can be driven by a motor to select the position of the electric furnace, and then the material is discharged through gate 304, which greatly reduces the degree of manual intervention. In addition, the furnace body can perform both melting and firing operations, greatly improving the applicability.
[0053] Once the alloy inside mold 401 is formed, cylinder 402 is activated. The positional change of the drive end of cylinder 402 can cause the moving plate 403 to change position. The positional change of the moving plate 403 can cause the fixed plate 404 to change position accordingly, causing multiple fixed shafts 406 to change position. This causes the fixed shafts 406 to push the top plate 408 out once. The positional change of the moving plate 403 causes the two moving blocks 409 to move upward. The outside of the moving block 409 touches the inclined surface of the irregular block 412, causing the moving block 409 to stop rising and releasing the lock between the moving block 409 and the positioning shaft 410.
[0054] When cylinder 402 continues to work, top plate 408 stops rising, causing the drive end of cylinder 402 to move plate 403 to change position. Plate 403 then drives multiple ejection shafts 405 to continue rising, performing secondary ejection of the formed alloy. The external structure of the electric furnace facilitates ejection, enabling more efficient removal of finished products, reducing manual operation difficulty and labor intensity, and preventing damage to alloy ingots due to improper operation. This improves production efficiency and finished product quality, ensuring smooth production.
[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
