Description

Technical Field

[0001] The invention belongs to the technical field of metal material processing, and in particular relates to an ultrasonic device and an alloy casting system for assisting alloy casting. Background Art

[0002] Currently, alloy casting improvements are primarily achieved through modification or electromagnetic stirring. Modification involves adding core elements that promote alloy formation, artificially increasing the number of cores in the alloy melt to achieve grain refinement. Electromagnetic stirring, on the other hand, uses the principle of electromagnetic induction to create a changing magnetic field through alternating current, interacting with the melt to create a regular flow and improve its structure.

[0003] The inventors of the above-mentioned improved method for alloy casting discovered that, while the modification process inevitably requires the addition of corresponding metamorphic elements to the melt, while achieving the goal of grain refinement, it also introduces contamination from foreign elements and fails to remove gases and eliminate other defects. Furthermore, the electromagnetic casting device not only requires improvements to existing furnace equipment, but also requires the generation of sufficiently strong fluid motion due to the interaction between the electromagnetic casting device and the melt, requiring the addition of a magnetic field strength of more than 10,000 times that of the Earth's magnetic field. This not only consumes a large amount of electricity but also has a certain impact on the surrounding environment. Therefore, the problems existing in alloy casting in the prior art need to be urgently addressed. Summary of the Invention

[0047] Example 1

[0048] The present invention relates to the application field of metal material processing and power ultrasound. The first aspect of the present invention provides an ultrasonic device for assisting alloy casting. In an application scenario, the ultrasonic device can be applied to the casting field of alloy melts, which includes process fields such as semi-continuous casting or die casting of alloys, wherein the alloy melts may include but are not limited to melts of lightweight alloys such as magnesium alloys and aluminum alloys, so that high-frequency ultrasonic vibrations are transmitted to the alloy melts through the ultrasonic device of the present invention, so that the alloy melts are vibrated and impurities are removed by ultrasonic vibration. The vibration impurity removal specifically includes but is not limited to, for example, degassing, grain refinement or homogenization, so that the mechanical properties of the alloy after grain refinement, such as yield strength, hardness and ductility, can be greatly improved. At the same time, the homogenization and degassing effects can also greatly improve the machinability and surface quality of the alloy, while improving the corrosion resistance of the alloy. This will be specifically illustrated by the following embodiments.

[0049] In one embodiment, Figure 1-Figure 5As shown, the ultrasonic device includes an ultrasonic energy outputter 1 , a connecting rod 2 and a vibration ring 3 .

[0050] Specifically, one end of the connecting rod 2 is fixed to the output end of the ultrasonic energy output device 1; the other end of the connecting rod 2 is fixed to the vibration ring 3. During installation, the other end of the connecting rod 2 can be fixed to any position on the vibration ring 3, so that the vibration energy output by the ultrasonic energy output device 1 is transmitted to the vibration ring 3 through the connecting rod 2 without modifying the existing furnace equipment. Preferably, the other end of the connecting rod 2 is fixed to the vibration ring 3 and can be set as follows: Figure 1-Figure 4 The method shown is that the other end of the connecting rod 2 is fixed to the edge of the vibration ring 3 (specifically including the inner edge and the outer edge, etc.), and the other end of the connecting rod 2 is fixed parallel to the edge of the vibration ring 3, so that the alloy melt A can be evenly added to the vibration ring 3 from the top of the vibration ring 3, wherein the fixed connection method may include but is not limited to, for example, laser welding or ultrasonic welding, etc., or fixed connection by setting a connector, etc., for example, reserving a threaded hole or a through hole at the edge, so that the other end of the connecting rod 2 is fixed to the edge of the vibration ring 3 by a threaded connector, and the other end of the connecting rod 2 and the output end of the ultrasonic energy outputter 1 of the amplitude transformer 1 can be specifically connected by, for example, a threaded method, etc., which is not limited here and can be selected according to the actual scenario. Alternatively, it can also be set as follows Figure 5 The manner shown, that is, the other end of the connecting rod 2 is vertically fixed to the edge of the vibration ring 3, can also make it possible to evenly add the alloy melt A into the vibration ring 3 from above the vibration ring 3. In the above embodiment, it can be understood that the ultrasonic energy outputter 1 is used to output vibration energy (high-frequency ultrasonic vibration) and transmit the vibration energy to the connecting rod 2, and the connecting rod 2 is used to transmit the vibration energy output by the ultrasonic energy outputter 1 to the vibration ring 3. The vibration ring 3 is arranged in the alloy melt A of the crystallizer 6, that is, the vibration ring 3 is arranged in the crystallizer 6 and immersed in the alloy melt A. The vibration ring 3 is used to transmit the vibration energy of the connecting rod 3 to the alloy melt A, so that the alloy melt A is vibrated and impurities are removed by the vibration energy.

[0051] The ultrasonic device in the above embodiment fixes the connecting rod 2 on the vibration ring 3 so that the connecting rod 2 transmits the vibration energy of the ultrasonic energy outputter to the vibration ring 3, so that the ultrasonic vibration energy is transmitted to the alloy melt A through the vibration ring 3, which not only removes impurities such as gas in the alloy melt A, but also plays a role in grain refinement and homogenization. After grain refinement, the mechanical properties of the alloy such as yield strength, hardness and ductility can be greatly improved. At the same time, the homogenization and degassing effects can also greatly improve the machinability and surface quality of the alloy, as well as its corrosion resistance, without introducing any new components (elements) into the alloy. In addition, the edges of the connecting rod 2 and the vibration ring 3 provided in the above embodiment are connected to form an asymmetric ultrasonic vibration structure, which is significantly different from the symmetrical structure of the conventional axial connection. There is no need to change the existing casting equipment (especially for vertical casting at the axial position of light alloys such as magnesium alloys and aluminum alloys). It can be used by simply building it on the existing alloy casting equipment, which can improve the applicability and flexibility of the ultrasonic device. In addition, the inventors found that in actual scenarios, in the casting of alloy melts, most of the ultrasonic treatment is required in the radial direction, that is, at the edge of the ingot. The setting method of the above embodiment can make the vibration ring 3 located near the liquid-solid interface between the alloy melt and the crystalline alloy in the crystallizer, so that the effects of ultrasonic vibration impurity removal and grain refinement can be more obvious and efficient, thereby improving the impurity removal efficiency of the alloy melt.

[0052] In one embodiment, Figure 1-Figure 5 As shown, the other end of the connecting rod 2 is fixed to the edge of the vibration ring 3. In this embodiment, by fixing the other end of the connecting rod 2 to the edge of the vibration ring 3, the vibration energy is transmitted to the edge of the vibration ring 3 through the connecting rod 2, and the vibration energy is transmitted to the alloy melt A through the vibration ring 3, so that the alloy melt A is removed from impurities such as gas under high-frequency vibration energy, while simultaneously achieving grain refinement and homogenization.

[0053] In one embodiment, Figure 4-Figure 8 As shown, the vibration ring 3 is an annular structure with a hole punched in the middle of its circumference. The vibration ring 3 is integrally formed, that is, it can be configured as a closed structure. Specifically, the vibration ring 3 can be made of materials including, but not limited to, ceramic, titanium alloy, or stainless steel, and formed integrally using processes corresponding to the materials. In one application scenario, the outer diameter of the vibration ring 3 can range from 50 mm to 500 mm. The vibration ring and connecting rod can also be integrally formed, specifically through processes such as casting or welding.

[0054] In the above embodiment, by setting the vibration ring 3 as an integrally formed structure, the loss of vibration energy can be reduced, thereby achieving uniform distribution of vibration energy in all directions of the vibration ring 3. As a result, when the alloy melt A is added into the vibration ring 3 from above the vibration ring 3, the vibration ring 3 uniformly transfers the vibration energy transmitted by the connecting rod 2 to the alloy melt A, thereby improving the impurity removal efficiency of the ultrasonic device on the alloy melt A.

[0055] In one embodiment, Figure 4 As shown, the vibration ring 3 may further be provided with a plurality of evenly distributed openings 31, wherein the plurality may be, for example, 4, 6, 8, or 12, etc., without specific limitation. Accordingly, the plurality of evenly distributed openings 31 may be symmetrically arranged on the vibration ring 3, wherein the openings 31 may be circular, elliptical, or polygonal, etc., without specific limitation and may be selected according to the actual scenario.

[0056] In the above embodiment, by providing a plurality of evenly distributed openings 31 on the vibration ring 3 , the added alloy melt A can flow into the crystallizer faster and more evenly, thereby improving the flow efficiency of the alloy melt A.

[0057] In one embodiment, Figure 6 and Figure 7 As shown, the vibration ring 3 can also be provided in a split configuration, that is, the vibration ring 3 can also be provided as a non-enclosed structure. Specifically, the vibration ring 3 includes multiple arc structures 32. Preferably, the multiple arc structures can be evenly arranged, that is, each arc structure has the same structure; the ultrasonic device includes a plurality of ultrasonic energy outputters 1 corresponding to the number of the multiple arc structures 32, and a connecting rod 2 respectively fixed to the output end of each ultrasonic energy outputter 1, wherein: each connecting rod 2 is correspondingly fixed to each arc structure 32, and each connecting rod 2 is used to transmit the vibration energy output by the corresponding ultrasonic energy outputter 1 to the corresponding arc structure 32.

[0058] In the above embodiment, by setting the vibration ring 3 as a split structure, vibration energy can be transmitted to the corresponding multiple arc structures 32 on the vibration ring 3 through multiple ultrasonic energy outputters 1 and connecting rods 2, so that each arc structure 32 corresponds to input vibration energy, thereby improving the vibration impurity removal efficiency of the vibration ring 3 on the alloy melt.

[0059] In one embodiment, Figure 6As shown, the arc structures 32 are all half rings, and the vibration ring 3 includes a first half ring 321 and a second half ring 322; the ultrasonic device includes a first ultrasonic energy outputter 1a1, a first connecting rod provided on the output end of the first ultrasonic energy outputter 1a1, a second ultrasonic energy outputter 1a2, and a second connecting rod provided on the output end of the second ultrasonic energy outputter 1a2, wherein: the first connecting rod is fixed to the edge of the first half ring; the second connecting rod is fixed to the edge of the second half ring.

[0060] In the above embodiment, by providing two half rings and a corresponding number of ultrasonic energy outputters 1 and connecting rods 2, the output energy can be transmitted to the alloy melt through the corresponding ultrasonic energy outputters 1 and connecting rods 2, respectively, so that the vibration energy received by the alloy melt on the vibration ring 3 is more uniform, thereby improving the impurity removal efficiency of the ultrasonic device on the alloy melt.

[0061] In one embodiment, Figure 7 As shown, the arc structures 32 are all one-third rings, and the vibration ring 3 includes a first arc 323, a second arc 324 and a third arc 325; the ultrasonic device includes a first ultrasonic energy outputter 1b1, a first connecting rod provided on the output end of the first ultrasonic energy outputter 1b1, a second ultrasonic energy outputter 1b2, a second connecting rod provided on the output end of the second ultrasonic energy outputter 1b2, a third ultrasonic energy outputter 1b3, and a third connecting rod provided on the output end of the third ultrasonic energy outputter 1b3, wherein: the first connecting rod is fixed to the edge of the first arc; the second connecting rod is fixed to the edge of the second arc; and the third connecting rod is fixed to the edge of the third arc.

[0062] In the above embodiment, by providing three uniform circular arcs and a corresponding number of ultrasonic energy outputters 1 and connecting rods 2, the output energy can be transmitted to the alloy melt through the corresponding ultrasonic energy outputters 1 and connecting rods 2, respectively, so that the vibration energy received by the alloy melt on the vibration ring 3 is more uniform, thereby improving the impurity removal efficiency of the ultrasonic device on the alloy melt.

[0063] It should be noted that, in addition to the two half rings and the corresponding two ultrasonic energy outputters 1, the three arcs and the corresponding three ultrasonic energy outputters 1 in the above embodiments, other types of multiple arc structures 32 may also be provided, for example Figure 8 The four arcs shown and the corresponding four ultrasonic energy outputters 1 (the first ultrasonic energy outputter 1c1, the second ultrasonic energy outputter 1c2, the third ultrasonic energy outputter 1c3 and the fourth ultrasonic energy outputter 1c4) or more than four arcs and the corresponding number of ultrasonic energy outputters 1, etc., are not described in detail here to avoid redundancy.

[0064] In one embodiment, Figure 1 and Figure 2 As shown, the ultrasonic energy outputter 1 includes a horn 11, a transducer 12, and an ultrasonic energy generator 13, which are connected in sequence. One end of the connecting rod 2 is fixed to the output end of the horn 11. The horn 11 is used to transfer the vibration energy output by the transducer 12 to the connecting rod 2, so that the connecting rod 2 transfers the vibration energy to the vibrating ring 3. In one application scenario, the transducer 12 can convert electrical energy into mechanical energy. Specifically, a sandwich piezoelectric transducer 12 or a magnetostrictive transducer 12 can be used. The operating frequency range of the transducer can be set to 15kHz-40Hz. The horn 11 is a cylindrical part with a variable cross-section that transmits vibration and adjusts the amplitude. Specifically, the transducer 12 is used to convert the electrical energy output by the ultrasonic energy generator 13 into mechanical vibrations of corresponding frequencies. The mechanical vibrations are adjusted by the amplitude transformer 11 and transmitted by the connecting rod 2, and finally excite the vibration ring 3 to vibrate according to the designed vibration mode, so that the vibration energy is transmitted through the vibration ring to the alloy melt that is about to be cooled into an ingot.

In one embodiment, Figure 1 As shown, the alloy casting system includes a melting furnace 4, a liquid guide pipe 5, a crystallizer 6, and the ultrasonic device of any one of the above-mentioned embodiments 1, wherein the molten alloy in the melting furnace 4 is transferred to the crystallizer 6 through the liquid guide pipe 5. Specifically, a cooling channel C (for example, a cooling channel for water circulation) can be provided on the outer wall of the crystallizer 6 to allow the molten metal A to be introduced into the crystallizer whose outer wall is cooled by water.

[0067] In one embodiment, Figure 1 As shown, the alloy casting system further includes a diverter plate 7, wherein:

[0068] The diverter plate 7 is disposed above the vibrating ring 3, and the diverter plate 7, the vibrating ring 3, and the crystallizer 6 are coaxially located. The diverter plate 7 diverts the molten alloy onto the vibrating ring 3. Specifically, the diverter plate 7 may be provided with a plurality of uniform openings 31 to disperse the molten alloy through the plurality of uniformly distributed openings, thereby controlling the flow rate of the molten alloy.

[0069] In the above embodiment, based on the above embodiment 1, the vibration energy of the ultrasonic energy outputter 1 is transmitted to the vibration ring 3 through the connecting rod 2. Furthermore, by arranging the diverter plate 7 above the vibration ring 3, and the diverter plate 7, the vibration ring 3 and the crystallizer 6 are on the same axis, the alloy melt can be added to the vibration ring 3 from the middle and evenly through the diverter plate 7, thereby improving the impurity removal efficiency of the ultrasonic device for the alloy melt.
