Description

Technical Field

[0001] This utility model relates to the field of non-vacuum induction furnace technology, and more specifically, to a novel non-vacuum induction furnace. Background Technology

[0002] Non-vacuum induction furnaces, as highly efficient metal melting equipment, are widely used in the melting and heat preservation processes of materials such as steel and non-ferrous metals. Their working principle is based on electromagnetic induction heating, using a medium-frequency power supply to generate an alternating magnetic field, inducing eddy currents within the metal charge to achieve rapid melting. Compared to other vacuum melting equipment, non-vacuum induction furnaces offer advantages such as simple structure, low cost, and high production efficiency, making them particularly suitable for scenarios requiring large-scale production with relatively low metal purity requirements.

[0003] However, in actual production, non-vacuum induction furnaces exhibit significant splashing problems when pouring molten metal from the gate, severely impacting production safety and product quality. In existing technologies, one of the main causes of gate splashing is an excessively large vertical distance between the gate and the molten metal container.

[0004] When the distance between the gate and the molten metal tank is too far, the high-temperature molten metal accelerates its descent under gravity, colliding violently with the liquid metal or solid cold material inside the container. This impact disrupts the surface tension of the molten metal, forming a large number of tiny droplets that splash. In addition, the long-distance free-falling molten metal stream carries a large amount of air, forming a gas-liquid mixture. When the stream enters the molten metal tank, the entrained air expands and bursts rapidly in the form of bubbles, generating local pressure pulses. This dynamic pressure change causes periodic fluctuations on the surface of the molten metal. When the amplitude of the fluctuations exceeds the splash threshold, continuous splashing occurs. Furthermore, the molten metal exchanges heat with the ambient air during its long descent, resulting in a significant drop in surface temperature. This temperature gradient causes a gradient change in the viscosity of the molten metal. The velocity difference between the outer high-viscosity layer and the inner low-viscosity core induces the Coanda effect, causing the stream to diverge. The diverging stream collides with the container wall, further intensifying the splashing.

[0005] In existing equipment designs, the distance between the gate and the molten ladle is primarily limited by the mechanical structure of the tilting mechanism and the required operating space. This excessive gate-vessel distance leads to splashing, which not only wastes metal materials but also poses a serious safety threat to operators.

[0006] Therefore, there is an urgent need to develop a new type of non-vacuum induction furnace that can adjust the distance between the gate and the molten ladle in real time and suppress the free fall of molten liquid, so as to fundamentally solve the splashing problem caused by long-distance casting.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Example 1

[0034] The following is in conjunction with the appendix Figure 1-6The present invention will be further described as follows:

[0035] This utility model provides a novel non-vacuum induction furnace 10. Please refer to [link / reference]. Figure 1-6 The novel non-vacuum induction furnace 10 includes an induction furnace body 100, a support frame 200, and a splash-proof device 300.

[0036] The support frame 200 has two symmetrically arranged support legs 210. The induction furnace body 100 is connected to the support frame 200 and is located between the two support legs 210. The induction furnace body 100 has a pouring port 110 for pouring liquid into the molten liquid tank 30.

[0037] In this embodiment, in order to automate the entire process, a conveyor belt 20 for transporting the molten ladle 30 is provided in front of the support frame 200. When the conveyor belt 20 transports the empty molten ladle 30 to below the gate 110, the induction furnace body 100 starts to tilt. At this time, the molten metal flows out from the gate 110 and is poured into the molten ladle 30.

[0038] In this embodiment, the structures of the induction furnace body 100, support frame 200, conveyor belt 20, and molten liquid can all refer to existing equipment. The improvement of this application lies in the structure of the anti-splash device 300 and its position and connection with the aforementioned equipment.

[0039] In this embodiment, the splash guard 300 is connected to the support frame 200 and is disposed below the gate 110.

[0040] The splash guard 300 includes two symmetrically arranged telescopic legs 310, two symmetrically arranged clamping assemblies 320, and two symmetrically arranged support assemblies 330.

[0041] In this embodiment, telescopic legs 310 are correspondingly disposed on the support legs 210, with the length direction of the telescopic legs 310 parallel to the length direction of the support legs 210. In this embodiment, the telescopic legs 310 are cylinders. The entire housing of the cylinder is fixedly connected to the support legs 210, and the housing has a fixed end 311. The end of the cylinder's telescopic rod furthest from the housing is designated as the telescopic end 312. In this embodiment, the fixed end 311 is fixedly connected to the support legs 210 near the bottom of the induction furnace body 100, and the telescopic end 312 extends towards the top of the induction furnace body 100.

[0042] The clamping assembly 320 includes an anti-slip plate 321, and a connecting arm 322, a telescopic arm 323, and a clamping arm 324 connected in sequence. The end of the connecting arm 322 away from the telescopic arm 323 is connected to the telescopic end 312 of the telescopic leg 310. The length direction of the connecting arm 322 is perpendicular to the length direction of the telescopic leg 310. The length direction of the telescopic arm 323 is perpendicular to both the length direction of the connecting arm 322 and the length direction of the telescopic leg 310. In this embodiment, the telescopic arm 323 is a cylinder, with one end of its housing connected to the connecting arm 322 and one end of its telescopic rod connected to the clamping arm 324.

[0043] In this embodiment, the two clamping arms 324 can be positioned far apart or close together, forming a clamping space 340 between them for clamping the molten liquid container 30. The clamping arms 324 have an arc-shaped cross-section along the length direction perpendicular to the support leg 210 to better match the shape of most molten liquid containers 30. Anti-slip plates 321 are fixedly disposed on the side of the clamping arm 324 facing the other clamping arm 324, thereby improving the clamping firmness between the clamping arms 324 and the molten liquid container 30.

[0044] In this embodiment, the support components 330 are connected to the telescopic arms 323 in a one-to-one correspondence. The support components 330 include a first support rod 331, an elastic element 332, and a second support rod 333 connected in sequence. The end of the first support rod 331 away from the elastic element 332 is hinged to the support frame 200, and the end of the second support rod 333 away from the elastic element 332 is hinged to the telescopic arm 323. When the telescopic end 312 approaches or moves away from the fixed end 311, the elastic element 332 is in a compressed state.

[0045] The structure of the support component 330 is designed to provide additional support to the clamping component 320, thereby making the clamping of the clamping component 320 to the molten liquid tank 30 more secure.

[0046] The novel non-vacuum induction furnace 10 provided in this embodiment works as follows: When the conveyor belt 20 transports the empty molten metal tank 30 to below the gate 110, the telescopic leg 310 (cylinder) is activated to retract. At this time, the telescopic end 312 of the telescopic leg 310 drives the clamping assembly 320 to move downward until the clamping arm 324 is below the opening of the molten metal tank 30. Then, the telescopic arm 323 (cylinder) is activated to extend, so that the clamping arm 324 clamps the molten metal tank 30. After the two clamping arms 324 clamp the molten metal tank 30, the telescopic leg 310 (cylinder) is activated again to extend, so that the telescopic end 312 of the telescopic leg 310 drives the clamping assembly 320 to move upward, so that the molten metal tank 30 moves closer to the gate 110 to a certain position. Subsequently, the induction furnace body 100 starts to tilt, and the molten metal flows out from the gate 110 and is poured into the molten metal tank 30.

[0047] In summary, this embodiment provides a novel non-vacuum induction furnace 10. The furnace features an ingenious structural design that enables automatic clamping and return of the molten metal vessel 30, allowing it to move closer to or further away from the gate 110. This significantly suppresses molten metal splashing, effectively preventing damage to equipment and workers caused by metal splashing in the production workshop, while also reducing metal waste.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
