Description

Technical Field

[0053] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0054] Figure 1 A schematic structural diagram of a purification device according to an embodiment of the present disclosure; Figure 2 A schematic structural diagram of another working state of a purification device according to an embodiment of the present disclosure.

[0055] like Figure 1 and Figure 2 As shown, a purification device proposed according to an embodiment of the present disclosure includes: a graphite crucible 100, having a purification tank 110, the purification tank 110 is used to hold a molten metal; an ultrasonic component 200, arranged at the notch of the purification tank 110, the ultrasonic component 200 is used to emit ultrasonic waves into the molten metal; a pulse component 300, the pulse component 300 includes a lifting part 310 and a pulse part 320, the lifting part 310 is arranged close to the outer wall of the purification tank 110, the pulse part 320 is arranged at the lifting part 310, the lifting part 310 is used to drive the pulse part 320 to move along the conducting direction of the notch, and the pulse part 320 is used to emit a pulse magnetic field into the molten metal; a hot-type continuous casting component 400, the purification tank 110 is formed with a liquid outlet at one end away from the notch, the hot-type continuous casting component 400 is arranged corresponding to the liquid outlet, and the hot-type continuous casting component 400 is used to condense the molten metal.

[0056] The purification device proposed according to the embodiment of the present disclosure includes a graphite crucible 100, an ultrasonic component 200, a pulse component 300 and a hot-type continuous casting component 400, wherein the purification tank 110 of the graphite crucible 100 is used to hold the molten metal, the hot-type continuous casting component 400 is arranged at the liquid outlet of the purification tank 110, so that the molten metal can be condensed on the hot-type continuous casting component 400, and an ultrasonic component 200 is arranged at the notch of the purification tank 110, and the ultrasonic component 200 can emit ultrasonic waves into the purification tank 110, and the ultrasonic component 200 is used to interfere with the solid-liquid interface during purification. When the metal melt solidifies, impurities gather near the solid-liquid interface. When ultrasonic waves propagate in the metal melt, alternating high and low pressures will be generated, causing tiny bubbles to form in the metal melt. The bubbles will burst violently in the high-pressure cycle, producing a cavitation effect, releasing strong shear forces and eddy currents, which can rapidly diffuse impurities in the impurity-enriched layer in the metal melt, reduce the degree of impurity aggregation, and help reduce the gold content of impurities wrapped when new particles are generated, thereby improving the purity of the metal melt after solidification; at the same time, when ultrasonic waves propagate in the metal melt, they will produce an acoustic streaming effect, causing the metal melt to flow, which will flush the crystal nuclei in the metal melt, making the crystal nuclei more evenly distributed in the melt, and the ultrasonic waves will cause the impurities in the metal melt to flow. The vibration of the sound wave can also promote nucleation, making it easier for the atomic clusters in the melt to reach the critical size and form more crystal nuclei. According to the solidification theory, the increase in the nucleation rate and the uniform distribution of the crystal nuclei are conducive to obtaining refined grains. A pulse assembly 300 is also provided outside the purification tank 110. The lifting part 310 of the pulse assembly 300 is arranged along the conduction direction of the notch of the purification tank 110. The pulse part 320 of the pulse assembly 300 is arranged on the lifting part 310. The pulse part 320 can emit a pulse magnetic field to the metal melt in the purification tank 110. As the pulse part 320 moves along the conduction direction of the notch of the purification tank 110, the pulse emitted by the pulse part 320 The pulse magnetic field can fully affect the molten metal in the purification furnace, so that the molten metal in the purification furnace obtains sufficient pulse magnetic field energy. Since the pulse part 320 applies an instantaneous, high-energy pulse magnetic field to the molten metal, it will cause energy fluctuations in the molten metal, so that the atomic clusters in the molten metal are distorted by the pulse magnetic field, and the atomic clusters gather and grow in large quantities, thereby increasing the nucleation points; and since the magnetic anisotropy of the material can affect the magnetic orientation, under the action of the pulse magnetic field, this magnetic anisotropy will cause the crystal nucleus to be affected by a torque, thereby rotating, and ultimately the material will be oriented along the crystallographic direction with the lowest magnetic energy, thereby making the grain orientation tend to be consistent.

[0057] It is understandable that the metal melt includes molten metal and some other impurities. The metal can be aluminum, copper, zinc, magnesium, etc., and no further limitations are given here.

[0058] It should be noted that, taking aluminum as an example, in the prior art, the device for purifying high-purity aluminum by segregation method often produces products with coarse grains and inconsistent orientation, and it is difficult to eliminate the influence during the processing and manufacturing process, resulting in subsequent cracks, orange peel effect and other quality problems in the finished product. Compared with the prior art, the purification device proposed in the embodiment of the present disclosure, based on the above-mentioned settings, can refine the metal grains, make the orientation of the grains tend to be consistent, improve the organizational properties of the grains, and improve the mechanical properties of the product such as elongation, tensile strength, cross-sectional shrinkage and hardness, which is conducive to improving the quality of the finished product.

[0059] In some examples, such as Figure 1 and Figure 2 As shown, the lifting part 310 includes: a slide rail 311, which extends along the conduction direction of the slot, and the pulse part 320 is slidably arranged on the slide rail 311; a first driving member, which is arranged on the pulse part 320 and is used to drive the pulse part 320 to slide along the slide rail 311; a control member 312, which is electrically connected to the first driving member and is used to control the driving direction of the first driving member; wherein the number of the pulse parts 320 is at least two, and at least two pulse parts 320 are arranged around the purification tank 110.

[0060] In the above technical scheme, the lifting part 310 includes a slide rail 311, a first driving member and a control member 312, wherein the control member 312 can control the first driving member, and the first driving member can drive the pulse part 320 to slide along the slide rail 311, and the extension direction of the slide rail 311 is the same as the conduction direction of the notch of the purification tank 110, so that when the pulse part 320 slides along the slide rail 311, the notch of the purification tank 110 to the liquid outlet of the purification tank 110 can be affected by the pulse magnetic field emitted by the pulse part 320. At the same time, the number of pulse parts 320 is at least two, and at least two pulse parts 320 are arranged around the purification tank 110, which can further ensure the coverage integrity of the pulse magnetic field, thereby facilitating the consistent orientation of the grains after condensation.

[0061] For example, the number of the slide rails 311 may correspond to the number of the pulse parts 320 , so that each pulse part 320 corresponds to one slide rail 311 , thereby avoiding interference between the pulse parts 320 during movement.

[0062] Exemplarily, the control unit may also be connected to the pulse unit 320 to control the emission of the pulse magnetic field of the pulse unit 320 .

[0063] In some examples, such as Figure 1 and Figure 2 As shown, the graphite crucible 100 further includes:

[0064] A smelting tank 120, the smelting tank 120 is connected to the purification tank 110, and the smelting tank 120 is used to smelt the solid metal into a metal melt;

[0065] The solidification channel 130 is disposed in the purification tank 110 . The solidification channel 130 is connected to the liquid outlet of the purification tank 110 . The hot mold continuous casting assembly 400 is used to be inserted in the solidification channel 130 .

[0066] The purification switch 140 is disposed at the liquid outlet of the purification tank 110 and is used to open or close the liquid outlet of the purification tank 110 .

[0067] In the above technical solution, the graphite crucible 100 also includes a smelting tank 120, which is used to melt solid metal into molten metal. The molten metal then flows from the smelting tank 120 to the purification tank 110. The liquid outlet of the purification tank 110 is provided with a purification switch 140. The liquid outlet of the purification tank 110 is connected to the solidification channel 130. The hot mold continuous casting component 400 is inserted into the solidification channel 130. In actual application, when the purification switch 140 is closed, a sufficient amount of metal solids or molten metal is directly added to the smelting tank 120. The molten metal can flow into the purification tank 110, and the pulse part 320 slides along the lifting part 310 and emits pulse magnetic field to the molten metal. The ultrasonic wave is emitted into the molten metal through the ultrasonic component 200. After the pulse magnetic field and the ultrasonic wave have fully acted on the molten metal, the hot type continuous casting component 400 is inserted into the solidification channel 130, and the purification switch 140 is turned on to make the molten metal flow into the solidification channel 130 from the liquid outlet. After the molten metal contacts the hot type continuous casting component 400, it is directionally solidified. After that, the hot type continuous casting component 400 can be gradually withdrawn from the solidification channel 130, so that the molten metal is gradually solidified between the hot type continuous casting component 400 and the liquid outlet. During the solidification period, the ultrasonic wave component 200 continuously emits ultrasonic waves to interfere with the solid-liquid interface, reduce the accumulation of impurities at the solid-liquid interface, and improve the purification purity.

[0068] It is understandable that the purification switch 140 may be closed according to actual conditions to prevent excessive overflow of the molten metal; preferably, the purification switch 140 is closed after the molten metal has completely solidified.

[0069] It is understandable that during the sliding process, the pulse portion 320 has a position corresponding to the solidification channel 130, so that the pulse portion 320 emits a pulse magnetic field to the molten metal inside the solidification channel 130, which is beneficial to ensure that the grain orientation of the molten metal is consistent after solidification.

[0070] Exemplarily, the smelting tank 120 and the purification tank 110 may be connected via the graphite crucible 100 tube, and the graphite crucible 100 tube, the smelting tank 120 and the purification tank 110 are an integrated structure.

[0071] Illustratively, the holding temperature in the smelting tank 120 is 670°C to 750°C, and specifically may be 670°C, 680°C, 690°C, 700°C, 710°C, 720°C, 730°C, 740°C or 750°C.

[0072] Exemplarily, the process parameters of the pulse magnetic field emitted by the pulse unit 320 are: pulse frequency: 10 Hz to 50 Hz; magnetic induction intensity: 100 mT to 500 mT; duty cycle: 10% to 50%; current: 100 A to 300 A; and processing time: 200 s to 400 s.

[0073] Exemplarily, the specific parameter ranges of the ultrasonic waves emitted by the ultrasonic component 200 are: power of 1 kW to 10 kW, frequency of 10 kHz to 60 kHz, and amplitude of 10 μm to 100 μm.

[0074] In some examples, such as Figure 1 and Figure 2 As shown, the graphite crucible 100 further includes: a resistance heater 150, which is arranged in the solidification channel 130 and is located at the connection between the solidification channel 130 and the liquid outlet.

[0075] In the above technical solution, the graphite crucible 100 also includes a resistance heater 150, which can heat the solidification channel 130, thereby reducing the possibility of nucleation on the inner wall of the solidification channel 130; it can increase the temperature gradient between the liquid outlet and the hot mold continuous casting component 400, which is more conducive to the directional solidification of the metal melt.

[0076] In some examples, such as Figure 1 and Figure 2 As shown, the graphite crucible 100 further includes a heating coil 160 , and the circumferences of the smelting tank 120 and the purification tank 110 are both surrounded by the heating coil 160 .

[0077] In the above technical solution, the graphite crucible 100 further includes a heating coil 160, which can heat the smelting tank 120 and the purification tank 110 to ensure a high temperature environment of the smelting tank 120 and the purification tank 110 so that the metal can maintain a molten state.

[0078] In some examples, such as Figure 1 and Figure 2 As shown, the hot type continuous casting assembly 400 includes: a dummy rod 410, which is inserted into the solidification channel 130, and the dummy rod 410 has a forming end, which is arranged toward the liquid outlet, and the forming end is used to solidify the metal melt; a traction member 420, which is connected to the dummy rod 410, and the traction member 420 is used to drive the dummy rod 410 to extend into or out of the solidification channel 130.

[0079] In the above technical solution, the hot mold continuous casting assembly 400 includes a dummy rod 410 and a traction member 420. The forming end of the dummy rod 410 is used to solidify the molten metal in the solidification channel 130, and the traction member 420 is used to guide the movement of the dummy rod 410. In actual application, the dummy rod 410 is inserted into the solidification channel 130, and the molten metal solidifies at the forming end of the dummy rod 410. The traction member 420 can pull the dummy rod 410 to gradually move in the direction of extending out from the solidification channel 130, thereby leaving space for the molten metal to solidify, so that the solidified amount of the molten metal can be gradually accumulated between the forming end of the dummy rod 410 and the liquid outlet of the purification tank 110.

[0080] It is understandable that the shaped end of the dummy bar 410 corresponds to the shape of the solidification channel 130 , which can prevent the molten metal from flowing out from between the peripheral wall of the dummy bar 410 and the inner wall of the solidification channel 130 .

[0081] Exemplarily, the traction speed of the traction member 420 is 10 cm / h to 100 cm / h, specifically 10 cm / h, 20 cm / h, 30 cm / h, 40 cm / h, 50 cm / h, 60 cm / h, 70 cm / h, 80 cm / h, 90 cm / h or 100 cm / h.

[0082] In some examples, such as Figure 1 and Figure 2 As shown, the hot mold continuous casting assembly 400 also includes: a second driving member connected to the ingot dummy rod 410, used to drive the ingot dummy rod 410 to rotate; a casting piece, arranged on the peripheral side of the ingot dummy rod 410; and a third driving member, used to drive the casting piece to move toward or away from the ingot dummy rod 410.

[0083] In the above technical solution, the hot mold continuous casting assembly 400 also includes a second driving member, a third driving member and a casting. In actual application, after the metal melt solidifies, purified solid metal can be obtained at the molding end of the ingot guide rod 410. Through the traction of the traction member 420, the purified solid metal can be gradually withdrawn from the solidification channel 130. At this time, the casting can be driven by the third driving member to move toward the direction close to the ingot guide rod 410, and the purified solid metal is squeezed by the casting to achieve the shaping of the purified solid metal. The third driving member can be used to drive the ingot guide rod 410 to rotate, so that the casting and the purified solid metal can be shaped in any direction.

[0084] Exemplarily, the number of the castings may be two, and the dummy rod 410 is disposed between the two castings, so that the extrusion force generated by the two castings approaching each other can be utilized to shape the purified solid metal, which is beneficial to improving the shaping effect.

[0085] In some examples, such as Figure 1and Figure 2 As shown, the hot mold continuous casting assembly 400 further includes: a cooler 430 , which is arranged toward the dummy bar 410 and is used to transport cooling liquid to the dummy bar 410 .

[0086] In the above technical solution, the hot mold continuous casting assembly 400 also includes a cooler 430, which transports cooling liquid to the dummy rod 410 to reduce the temperature of the dummy rod 410, thereby generating a temperature difference between the molten metal and the forming end of the dummy rod 410, which is beneficial to increasing the solidification speed of the molten metal on the dummy rod 410.

[0087] In some examples, such as Figure 1 and Figure 2 As shown, the ultrasonic component 200 includes: an ultrasonic generator 210, which is arranged in the notch of the purification tank 110; an energy concentrator 220, which is connected to the ultrasonic generator 210; a horn 230, which is connected to the energy concentrator 220, and the horn 230 extends into the purification tank 110; and an ultrasonic controller 240, which is used to control the ultrasonic generator 210.

[0088] In the above technical solution, the ultrasonic component 200 includes an ultrasonic generator 210, a concentrator 220, a horn 230 and an ultrasonic controller 240. The ultrasonic controller 240 can control the ultrasonic generator 210 to emit ultrasonic waves. The concentrator 220 is connected to the ultrasonic generator 210. The concentrator 220 can amplify ultrasonic waves, so that the ultrasonic waves are concentrated in a specific direction to increase the energy density of the ultrasonic waves. The concentrator 220 is connected to the horn 230. The horn 230 can amplify the amplitude of the ultrasonic waves. The ultrasonic waves amplified by the concentrator 220 can be emitted into the purification tank 110 through the horn 230, which is beneficial to improve the effect of ultrasonic waves on the metal melt.

[0089] In some examples, such as Figure 1 and Figure 2 As shown, it also includes: a cover body 510, which is arranged at the notch of the purification tank 110, and the ultrasonic component 200 is penetrated through the cover body 510, and the cover body 510 is used to cover or open the notch of the purification tank 110.

[0090] It is understandable that due to the vibration of the ultrasonic wave, the molten metal may splash. The cover 510 is provided at the notch of the purification tank 110 to prevent the molten metal from splashing and improve safety.

[0091] Exemplarily, the notch of the smelting tank 120 is also provided with a cover 510 , and the cover 510 is used to cover or open the notch of the smelting tank 120 .

[0092] In some feasible embodiments, the aluminum with a smelting purity of 99.85% is melted in the smelting tank 120, and the insulation temperature of the smelting tank 120 is 670°C; the parameters of the pulse magnetic field emitted by the pulse part 320 are: pulse frequency 10Hz, magnetic induction intensity 100mT, duty cycle 10%, current 100A, time 200s; the parameters of the ultrasonic wave emitted by the ultrasonic component 200 are: power 1kW, frequency 10kHz, amplitude 10μm; the traction speed of the traction member 420 is 10cm / h.
