Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum electric arc furnace technology, and in particular to a structure of a high-efficiency and energy-saving vacuum electric arc furnace for titanium alloy melting. Background Technology
[0002] A vacuum arc furnace is a type of vacuum metallurgical smelting equipment. The furnace body is a sealed container, evacuated or filled with an inert gas. An electric arc is generated by energizing electrodes introduced from the top of the furnace and igniting a water-cooled crystallizer at the bottom. The heat from the arc melts the metal or alloy, which then solidifies within the crystallizer. Furnaces with electrodes made of the metal being smelted are called "consumable electrode vacuum arc furnaces," while those using non-meltable materials are called "non-consumable electrode vacuum arc furnaces." The resulting products have fewer impurities, lower gas content, better ingot structure, and excellent mechanical and physical properties. They are suitable for smelting high-melting-point metals, reactive metals, special steels, and other metals.
[0003] Patent publication number CN219037555U discloses a vacuum electric arc furnace. The furnace includes a furnace body, a track surrounding the outer wall of the furnace body, a cooling plate that slides along the track, a circulation assembly connected to the cooling plate, and a locking assembly for locking the cooling plate in position on the outer wall of the furnace body. In use, the cooling plate is first placed on the area of the furnace body requiring cooling, and then its position on the track is locked. The circulation assembly then supplies circulating cooling medium to the cooling plate, thereby achieving localized temperature control of the furnace body. This invention reduces water consumption while simultaneously achieving localized temperature control of the furnace body.
[0004] However, when this patent cools a local area of the furnace body, the position of the cooling plate outside the furnace body needs to be manually adjusted. The cooling plate cannot be automatically adjusted to the position outside the furnace body, making the equipment not automated enough. Utility Model Content

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.
[0022] Reference Figures 1 to 4This utility model provides a high-efficiency and energy-saving vacuum electric arc furnace structure for titanium alloy smelting: It includes a furnace body 3, a barrel 1 rotatably sleeved on the outside of the furnace body 3, a driving component fixedly connected to the top surface of the barrel 1, the driving component being connected to the furnace body 3 via transmission, a water tank 8 fixedly connected to the outside of the barrel 1, a cooler 6 fixedly connected to the top surface of the water tank 8, a heat-conducting block 12 slidably connected inside the barrel 1, two cylinders 18 horizontally and symmetrically fixed to the outside of the heat-conducting block 12, the piston rod ends of the two cylinders 18 fixedly connected to the inner wall of the barrel 1, an arc-shaped groove adapted to the outer edge of the furnace body 3 provided on one side of the heat-conducting block 12, a water cavity provided inside the heat-conducting block 12, the water cavity being connected to the water tank 8 via a pipe, and a water pump 7 fixedly connected to the side of the water tank 8. The input end of the water pump 7 is fixedly connected to an L-shaped pipe, which is fixedly connected inside the water tank 8. The output end of the water pump 7 is fixedly connected to a delivery pipe 5. The center of the top surface of the cooler 6 is fixedly connected to a return pipe 11. The ends of the return pipe 11 and the delivery pipe 5 are respectively fixedly connected to a connector 4. The two connectors 4 slide through the barrel 1 and are fixedly connected to the heat-conducting block 12. The return pipe 11 and the delivery pipe 5 are both flexible hoses. The outer edge of the furnace body 3 is symmetrically fitted with a first annular plate 2 and a second annular plate 13. The first annular plate 2 and the second annular plate 13 are both fixedly connected inside the barrel 1. The driving component is fixedly connected to the top surface of the first annular plate 2. The side of the water tank 8 is fixedly connected to a replenishment pipe 10. The side of the water tank 8 is provided with a water level line 9.
[0023] The driving component includes a drive motor 17 horizontally fixed to the top surface of the first annular plate 2. The output end of the drive motor 17 is connected to a rotating shaft 16. The end of the rotating shaft 16 is coaxially fixed to a gear 14. The top surface of the furnace body 3 is coaxially formed with an annular toothed groove 15. The gear 14 meshes in the toothed groove 15. A support rod 19 is fixedly connected to the inner wall of the barrel 1. A temperature sensor 20 is fixedly connected to the end of the support rod 19. An arc-shaped heat-conducting plate 21 is fixedly connected to the end of the temperature sensor 20. The arc-shaped heat-conducting plate 21 is slidably connected to the outer wall of the furnace body 3, and the support rod 19 is located above the heat-conducting block 12.
[0024] By rotating the furnace body 3 inside the barrel 1, and sliding a heat-conducting block 12 with an internal water cavity inside the barrel 1, and connecting the water cavity to the water tank 8 through a pipe, the heat-conducting block 12 can automatically move to the position of the furnace body 3 that needs to be cooled, without the need for manual adjustment of the position of the heat-conducting block 12 outside the furnace body 3. This makes the local temperature control of the furnace body 3 more intelligent. The temperature sensor 20 is set to facilitate real-time detection of the temperature of the furnace body 3, so that the heat-conducting block 12 can accurately move to the position of the furnace body 3 that needs to be cooled.
[0025] Working principle: During operation, the drive motor 17 drives the rotating shaft 16 to rotate, which in turn drives the gear 14 to rotate. The gear 14, through the tooth groove 15, drives the furnace body 3 to rotate at a low speed. Simultaneously, the temperature sensor 20 monitors the temperature of the furnace body 3 in real time. When the temperature sensor 20 detects that the temperature at a certain location of the furnace body 3 is too high, the drive motor 17 stops. Then, the cylinder 18 pushes the arc-shaped groove on the inner side of the heat-conducting block 12 to fit against the outside of the furnace body 3. The water pump 7 draws water from the water tank 8 and sends it to the heat-conducting block 12 through the delivery pipe 5. Inside the water chamber, the temperature on the furnace body 3 is transferred to the heat-conducting block 12. The water in the water chamber absorbs the heat absorbed by the heat-conducting block 12 and flows to the cooler 6 through the return pipe 11. The cooled water returns to the water tank 8 and is then pumped back to the water chamber in the heat-conducting block 12 by the water pump 7. When the temperature sensor 20 detects that the temperature of the furnace body 3 has recovered from being too high, the cylinder 18 drives the heat-conducting block 12 to separate from the outside of the furnace body 3. Then, the drive motor 17 continues to drive the furnace body 3 to rotate through the gear 14 and the tooth groove 15.
[0026] 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.
