Description

Technical Field

[0001] This utility model belongs to the field of high-temperature furnace technology, specifically a high-temperature furnace for melting high-entropy alloy materials. Background Technology

[0002] High-entropy alloys are novel alloys composed of five or more elements mixed in equimolar or near-equimolar ratios. They break away from the traditional alloy design concept based on one or two principal elements. Their "high-entropy effect" promotes solid solution formation, suppresses brittle phases, and endows them with unique properties such as high strength, high hardness, excellent wear resistance, corrosion resistance, high-temperature stability, and good toughness. These superior properties give them broad application prospects in aerospace, nuclear industry, biomedicine, and other fields, making them a research hotspot in materials science. However, when melting high-entropy alloys, different materials need to be sequentially added to the same melting furnace for melting and mixing. Traditional high-temperature melting furnaces require opening the furnace lid when adding materials, which easily leads to heat loss and can also cause injury to workers. Therefore, improvements are needed to address these issues. Utility Model Content

[0013] 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.

[0014] Depend on Figures 1 to 3 The present invention includes a furnace body 1, a furnace cover 2, and a smelting crucible 5. The furnace cover 2 is movably installed on the top of the furnace body 1. An installation cover 3 is installed inside the furnace body 1, and a motor heating coil 4 is installed inside the installation cover 3. The smelting crucible 5 is movably installed inside the installation cover 3 and located inside the motor heating coil 4. A square installation opening 6 is provided on the upper part of the surface of the furnace body 1. A moving block 7 is installed through the square installation opening 6. A square conveying groove 8 is provided in the middle of the moving block 7. A feeding pipe 9 communicating with the square conveying groove 8 is fixedly installed at the bottom end of the moving block 7 inside the furnace body 1. A feeding hopper 10 communicating with the square conveying groove 8 is fixedly installed at the top of the moving block 7 outside the furnace body 1. A pusher plate 11 matching and movable and adjustable to the square conveying groove 8 is installed inside the square conveying groove 8. An observation window 12 is installed on the upper part of the furnace body 1. An outlet 19 is provided at the bottom end of the moving block 7 outside the furnace body 1. A limit stop 20 is fixedly installed at the top of the moving block 7 outside the furnace body 1.

[0015] The top of the square conveying trough 8 is provided with adjusting transverse grooves 13 at both ends. The feeding hopper 10 is located between the two adjusting transverse grooves 13. Threaded rods 14 are rotatably installed inside the two adjusting transverse grooves 13. The surfaces of the two threaded rods 14 are threadedly connected to sliders 15 that are fixedly connected to the top of the pusher plate 11. One end of each threaded rod 14 extends to the outside of one end of the moving block 7 and is fixedly connected to a gear 16. The two gears 16 mesh with each other. An n-shaped block 17 is fixedly installed on the top of one end of the moving block 7. A motor 18 is installed on one end of the n-shaped block 17. The output end of the motor 18 is fixedly connected to the shaft of one of the gears 16. The motor 18 can rotate forward and backward to adjust, thereby effectively feeding the material into the interior of the melting crucible 5.

[0016] Specifically, material is added into the square conveying trough 8 through the feeding hopper 10. Then, the motor 18 is started to drive one of the gears 16 to rotate. The rotation of one gear 16 causes the two threaded rods 14 to rotate synchronously through the other gear 16. The rotation of the two threaded rods 14 causes the two sliders 15 to move, which in turn moves the pusher plate 11. The movement of the pusher plate 11 pushes the material inside the square conveying trough 8, and finally adds the material into the melting crucible 5 through the feeding pipe 9 located directly above the melting crucible 5. Then, the motor 18 is started in reverse to move the pusher plate 11 back to its original position, and the material can be fed again.

[0017] Two threaded shafts 21 are symmetrically rotatably connected to the upper part of the surface of the furnace body 1 through a square mounting port 6. A sprocket 22 is fixedly connected to one end of each threaded shaft 21. A chain 23 is installed between the two sprockets 22. A rotating wheel 24 is fixedly installed at the axis of one of the sprockets 22. Adjusting blocks 25 are fixedly installed on both sides of the surface of the moving block 7. The two adjusting blocks 25 are threadedly connected to the two threaded shafts 21 respectively, so that the feeding pipe 9 can be effectively adjusted to be directly above the melting crucible 5.

[0018] Rotating one of the sprockets 22 via the rotating wheel 24 causes the other sprocket 22 to rotate via the chain 23. The rotation of the two sprockets 22 causes the two threaded shafts 21 to move. The rotation of the two threaded shafts 21 causes the two adjusting blocks 25 to move. The movement of the two adjusting blocks 25 causes the moving block 7 to move. At the same time, the limiting block 20 limits the moving block 7 to move the feeding pipe 9 to directly above the melting crucible 5.

[0019] This high-temperature furnace for melting high-entropy alloy materials features a telescopic movement and conveying feeding structure. This structure safely and effectively adds materials into the furnace, preventing heat loss and injuries to workers caused by high temperatures. This significantly improves the practicality of the high-temperature furnace. Furthermore, the furnace has a simple design, is easy to use and operate, and its telescopic movement and conveying feeding are stable and reliable. Its performance meets the requirements for high-temperature furnace melting.
