[0002] High-entropy alloys are a new type of alloy material with excellent properties such as high strength, high hardness, good wear resistance, and corrosion resistance, making them promising for applications in aerospace, machinery manufacturing, and energy fields. During the smelting process of high-entropy alloys, stirring of the molten alloy is usually required to ensure thorough and uniform mixing of various alloying elements and improve the quality and performance of the alloy material.

[0003] In the prior art, traditional stirrers are difficult to fully convect and mix alloy materials in a high-temperature molten state, resulting in component segregation, uneven distribution of metal elements with large density differences, local enrichment, formation of coarse dendrite structures and micro-defects, causing fluctuations in the hardness, toughness, corrosion resistance and other properties of the alloy product. Therefore, this application proposes a magnetic stirring device for melting high-entropy alloy materials. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 4 This invention discloses a magnetic stirring device for melting high-entropy alloy materials, comprising a base plate 1, a melting furnace body 2, and a stirring mechanism 3, wherein the stirring mechanism 3 is disposed above the base plate 1; the stirring mechanism 3 consists of a mounting box 4, a mounting frame 5, a first motor 6, a driving gear 7, a first driven gear 8, a second driven gear 9, a first mounting shaft 10, a second mounting shaft 11, a scraper 12, a mounting rod 13, and a stirring rod 14. The mounting box 4 is fixed to the top surface of the melting furnace body 2, and the mounting frame 5 is fixed inside the mounting box 4. The driving gear 7, the first driven gear 8, and the second driven gear 9 are rotatably connected inside the mounting frame 5. The driving gear 8 and the second driven gear 9 both mesh with the driving gear 7. One side of the first driven gear 8 is fixed to the first mounting shaft 10. The outer wall of the first mounting shaft 10 is rotatably connected to the second mounting shaft 11. One side of the second driven gear 9 is fixed to the second mounting shaft 11. Several scrapers 12 are fixed to the outer wall of the first mounting shaft 10. One side of each scraper 12 is in contact with the inner wall of the smelting furnace body 2. One side of the second mounting shaft 11 is fixed to the mounting rod 13. Several stirring rods 14 are fixed to the outer wall of the mounting rod 13. The first motor 6 is fixed inside the mounting box 4. The output end of the first motor 6 is fixed to the driving gear 7.

[0022] The first motor 6 is started, and its output drives the drive gear 7 to rotate. The drive gear 7 meshes with the first driven gear 8 and the second driven gear 9, thereby causing the first driven gear 8 and the second driven gear 9 to rotate. The first driven gear 8 drives the first mounting shaft 10 to rotate, causing the scraper 12 fixed on the first mounting shaft 10 to rotate along the inner wall of the melting furnace body 2, which can scrape off the alloy molten material and other substances adhering to the inner wall. At the same time, the second driven gear 9 drives the second mounting shaft 11 to rotate, which causes the stirring rod 14 to rotate through the mounting rod 13, stirring the high-entropy alloy material in the melting furnace, promoting uniform mixing of the alloy composition. The stirring rod 14 can make the composition of the high-entropy alloy material more uniform during the melting process, which is beneficial to improving the quality and performance of the alloy. The scraper 12 can promptly clean the molten material adhering to the inner wall of the melting furnace, preventing it from solidifying and affecting the melting effect. It also facilitates equipment cleaning and extends the service life of the equipment.

[0023] The top surface of the smelting furnace body 2 is connected to a crushing box 15, and two crushing rollers 16 are rotatably arranged inside the crushing box 15, and the two crushing rollers 16 rotate in opposite directions.

[0024] Two crushing rollers 16 rotate in opposite directions. When the high-entropy alloy raw material enters the crushing box 15 through the feeding funnel 18, it will be clamped by the gap between the two crushing rollers 16. As the crushing rollers 16 rotate, the raw material is crushed by compression and shearing. The crushed raw material falls into the melting furnace body 2 for melting. Crushing the raw material before melting can increase the contact area between the raw material and the heat source in the melting furnace, making the raw material melt faster and more uniformly, improving the melting efficiency, and also helping to improve the uniformity of the alloy composition.

[0025] Two second motors 17 are fixed to the outer wall of the crushing box 15, and the two second motors 17 are respectively fixed to one end of the two crushing rollers 16;

[0026] The second motor 17 is started, and its output end drives the crushing roller 16 connected to it to rotate, which can realize the opposite rotation of the two crushing rollers 16, providing power for the crushing of raw materials. The rotation of the crushing roller 16 can be controlled according to the characteristics of different raw materials and crushing requirements, so as to achieve the ideal crushing effect and ensure the smooth progress of the smelting process.

[0027] A feeding funnel 18 is fixed on the top surface of the crushing box 15, and a molten liquid outlet 19 is provided at the bottom of the smelting furnace body 2.

[0028] The feeding funnel 18 is used to conveniently pour high-entropy alloy raw materials into the crushing box 15, and plays a role in guiding the raw materials. The molten liquid outlet 19 at the bottom of the melting furnace body 2 is opened after melting to allow the molten high-entropy alloy liquid to flow out for subsequent processing or forming processes. The feeding funnel 18 makes the feeding process more convenient and efficient, and can reduce the spillage of raw materials. The molten liquid outlet 19 provides a channel for the discharge of molten liquid.

[0029] Several support columns 20 are fixed on the top surface of the base plate 1, and one side of each support column 20 is fixed to the bottom outer wall of the furnace body 2.

[0030] The support column 20 is fixed on the base plate 1, and its upper end is connected to the bottom outer wall of the smelting furnace body 2. Through the support of the support column 20, the smelting furnace body 2 is stably supported above the base plate 1, so that the smelting furnace body 2 maintains a certain height, which is convenient for operators to carry out operations such as feeding and observation.

[0031] During operation, the high-entropy alloy raw material falls into the crushing box 15 through the feeding funnel 18 and enters the gap between the two crushing rollers 16. The second motor 17 is started, and its output end drives the two crushing rollers 16 to rotate, crushing the raw material into fine particles. The crushed raw material falls into the melting furnace body 2 through the bottom opening of the crushing box 15. The first motor 6 is started, and its output end drives the drive gear 7 to rotate. The drive gear 7 simultaneously meshes with the first driven gear 8 and the second driven gear 9. Due to the gear meshing transmission characteristics, the first driven gear 8 rotates counterclockwise, and the second driven gear 9 rotates clockwise. The second driven gear 9 drives the second mounting shaft 11 to rotate clockwise. Through the mounting rod 13, the stirring rod 14 makes a circular motion inside the melting furnace body 2, applying mechanical stirring force to the high-entropy alloy material, promoting uniform mixing of the alloy components in the molten state and avoiding segregation. The first driven gear 8 drives the first mounting shaft 10 to rotate counterclockwise, and the scraper 12 fixed on the first mounting shaft 10 rotates along the inner wall of the melting furnace body 2. Because the scraper 12 is in close contact with the inner wall, it can scrape off the attached molten alloy in real time, preventing solidification residue from affecting the smelting effect, while reducing the amount of manual cleaning work.
