[0024] 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.

[0025] Example 1: Please refer to Figures 1 to 5 The present invention provides the following technical solution:

[0026] A melting device for aluminum alloy billets includes a base 1. Two symmetrically distributed support rods 2 are fixedly connected to one end of the top of the base 1. Telescopic rods 3 are hinged to both sides of the top of the base 1. A furnace body 4 is installed on the top of the base 1. An open chamber 6 is provided at the upper end of the furnace body 4. A refractory ring 7 is fixedly connected inside the open chamber 6. The inner side of the refractory ring 7 and the inner side of the furnace body 4 form an installation cavity. A crucible 8 is detachably connected inside the installation cavity. Fixed ears 9 are fixedly connected to both sides of the top of the crucible 8. A hand-tightening bolt 10 is slidably connected to the top of the fixed ears 9. The hand-tightening bolt 10 passes through the fixed ears 9 and is threadedly connected to the refractory ring 7. A handle 11 is fixedly connected to the top of the end of the fixed ears 9. A sandwich layer 5 is provided inside the lower end of the furnace body 4. The top of the two telescopic rods 3 are respectively hinged to the middle of both sides of the furnace body 4. The top of the furnace body 4 is hinged to the top of the support rods 2.

[0027] The fire-resistant ring 7 has symmetrically distributed mounting grooves 12 on both sides of its top. The fixing ear 9 is engaged and connected inside the mounting groove 12. The mounting groove 12 is fixedly connected to a threaded ring 13 aligned with the hand-tightening bolt 10. The threaded ring 13 is threadedly connected to the lower end of the hand-tightening bolt 10.

[0028] Place the crucible 8 into the mounting cavity formed by the inner side of the refractory ring 7 and the inner side of the furnace body 4, so that the fixing ears 9 on both sides of the top of the crucible 8 are engaged in the mounting groove 12 on the top of the refractory ring 7. At this time, the hand-tightening bolt 10 on the top of the fixing ear 9 is aligned with the threaded ring 13 in the mounting groove 12. By rotating the hand-tightening bolt 10, it is made to pass through the fixing ear 9 and be threadedly connected to the threaded ring 13, thereby stably fixing the crucible 8 in the mounting cavity and preventing the crucible 8 from shifting during the melting process.

[0029] During the smelting process, the angle of the furnace body 4 can be adjusted by the telescopic rod 3. Since the middle of both sides of the furnace body 4 is hinged to the top of the two telescopic rods 3 respectively, and one end of the top of the furnace body 4 is hinged to the top of the support rod 2, when the telescopic rod 3 extends or shortens, it will drive the furnace body 4 to rotate around the hinge point with the support rod 2 as the fulcrum, thereby adjusting the tilt angle of the furnace body 4 to adapt to operations such as feeding and observing the smelting status.

[0030] The base 1 provides stable support for the entire device. The support rod 2 and the telescopic rod 3 work together to bear the weight of the furnace body 4 and internal components. The interlayer 5 at the lower end of the furnace body 4 provides installation space for the internal heating structure. The refractory ring 7 protects the furnace body 4 and helps to fix the crucible 8 through its own high-temperature resistance. When it is necessary to remove the crucible 8, the hand-tightening bolt 10 is rotated in the opposite direction to disengage it from the threaded ring 13. The crucible 8 can be removed from the installation cavity by pulling the handle 11 at the end of the fixing lug 9. The operation is convenient and facilitates the replacement, cleaning and maintenance of the crucible 8.

[0031] Example 2: Based on Example 1, please refer to... Figures 3 to 6 The following structure was also disclosed:

[0032] The crucible 8 has a root spout 14 in the middle on the side near the support rod 2, and the refractory ring 7 has an end spout 15 on the side near the support rod 2. When the crucible 8 is installed inside the installation cavity, the root spout 14 and the end spout 15 are spliced ​​together to form a complete flow channel.

[0033] An electric drive assembly 16 is fixedly connected to one side of the top of the furnace body 4. A sealing cover 17 is installed on the top of the furnace body 4, which is driven to rotate by the electric drive assembly 16 as the rotating axis. The sealing cover 17 covers the top of the furnace body 4 and is aligned with the top of the refractory ring 7. A sealing block 18 is fixedly connected to the bottom of the end of the sealing cover 17 away from the electric drive assembly 16. When the sealing cover 17 is in the closed state, the sealing block 18 is engaged inside the root nozzle 14 to form a sealing structure.

[0034] The interlayer 5 is fixedly connected to a fire-resistant insulating layer 19, a magnetic yoke 20, a coil 21 and a heat insulation layer 22 distributed from the inside out. The coil 21 is fixed inside the interlayer 5 by the magnetic yoke 20. The height of the molten metal inside the crucible 8 does not exceed the height of the interlayer 5.

[0035] During heating, the coil 21 in the lower interlayer 5 of the furnace body 4 is energized to generate an alternating magnetic field. The magnetic yoke 20, through its high magnetic permeability, focuses the magnetic field and guides it to the crucible 8, causing the aluminum alloy billet in the crucible 8 to generate eddy currents due to electromagnetic induction and melt. The refractory insulation layer 19 distributed from the inside to the outside of the interlayer 5 can reduce the conduction of heat to the furnace body 4 and prevent leakage. The heat insulation layer 22 further blocks the heat from spreading outward, improving heating efficiency. At the same time, the height of the molten metal inside the crucible 8 does not exceed the height of the interlayer 5, which can ensure that the molten metal is within the effective range of the magnetic field and ensure heating uniformity.

[0036] During the smelting process, the sealing cover 17 can be opened and closed by the electric drive assembly 16. The electric drive assembly 16 drives the sealing cover 17 to rotate around it. When the sealing cover 17 is closed, it covers the top of the furnace body 4 and aligns with the top of the refractory ring 7. At the same time, the sealing block 18 at the bottom of the end of the sealing cover 17 engages with the inside of the root spout 14 of the crucible 8, forming a sealing structure, which can reduce heat loss and gas leakage during the smelting process. When it is necessary to add material or observe, the electric drive assembly 16 drives the sealing cover 17 to rotate and open in the opposite direction.

[0037] During discharge, the tilt angle of the furnace body 4 is adjusted by the telescopic rod 3, causing the crucible 8 to tilt accordingly. Since the crucible 8 is installed inside the installation cavity, its root spout 14 and the end spout 15 of the refractory ring 7 form a complete flow channel. During the tilting process, the molten metal in the crucible 8 can flow out in a directional manner along this flow channel, achieving orderly discharge. After the discharge is completed, the telescopic rod 3 is adjusted to reset the furnace body 4, and the sealing cover 17 is closed, completing one smelting cycle.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
