Description

Technical Field

[0001] The invention relates to the technical field of metal smelting, and in particular to a high-temperature alloy purification smelting furnace and a smelting method. Background Art

[0002] Alloy purification smelting is an important metallurgical process, which involves removing impurity elements in the alloy to improve the purity and performance of the alloy. By precisely controlling the smelting temperature, component ratio and casting process, the overall performance of the alloy can be improved to ensure its long-term service life in complex environments.

[0003] In the prior art, in order to ensure the pure smelting of the alloy, it is usually necessary to cooperate with a filtering mechanism to filter impurities from the alloy in the molten state. The filtering mechanism is composed of a filter screen and a ceramic composite material, wherein the filter screen is used to remove relatively coarse inclusions in the alloy melt, while the ceramic composite material is responsible for more delicate impurity filtering. After the filtering mechanism maintains purification and filtration for a period of time, it will affect the circulation of the alloy melt due to the attachment of impurities, thereby affecting the efficiency of pure alloy smelting.

[0004] The prior art usually adopts a method of closing the alloy solution circulation channel. After the user completes the replacement of the filtering structure in the channel, the molten alloy is continued to be filtered and purified. However, since the channel responsible for filtering the molten alloy is at a relatively high temperature in a short period of time, the user is unable to replace the filtering structure in the channel in time, resulting in the prior art being not conducive to human operation and unable to meet the problem of efficient purification and smelting of the molten alloy.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figure 1-6The present invention provides a technical solution: a high-temperature alloy purification smelting furnace, comprising a base 1, an equipment frame 2 fixed on the base 1, a protective atmosphere furnace 3 and a smelting furnace body 4 installed on the equipment frame 2, a pressurizing chamber 19 is installed on the base 1, a turntable 5 is rotatably arranged between the pressurizing chamber 19 and the smelting furnace body 4, a plurality of second butt joint pipes 17 are slidably penetrated inside the turntable 5, a first butt joint pipe 10 is screwed and connected in the second butt joint pipe 17, the first butt joint pipe 10 and the second butt joint pipe 17 are respectively used for butt jointing the output port of the smelting furnace body 4 and the input port of the pressurizing chamber 19, a component for controlling the sliding and extension of the first butt joint pipe 10 and the second butt joint pipe 17, and a driving component for controlling the rotation of the turntable 5 are arranged on the equipment frame 2, a filtering structure is arranged in the first butt joint pipe 10, and a retaining frame 18 corresponding to the first butt joint pipe 10 is fixed on the turntable 5.

[0037] When the alloy is melted in the melting furnace body 4, the protective atmosphere furnace 3 protects the metal material by controlling the atmosphere composition and flow rate in the furnace. Commonly used atmospheres include hydrogen, nitrogen, argon, etc. These gases can enter the furnace through the gas pipe and nozzle in the furnace. The atmosphere control system can control the proportion of different atmospheres according to the heat treatment requirements of different metal materials to prevent the metal material from oxidizing at high temperature or having undesirable chemical reactions with other components in the environment.

[0038] When the alloy is heated and melted in the smelting furnace body 4, the output port at the bottom of the smelting furnace body 4 is opened through the control of the electric valve, and the alloy melt in the smelting furnace body 4 will flow into the first butt joint pipe 10, and after passing through the filtering structure, it will flow to the booster chamber 19 through the second butt joint pipe 17. When a large number of impurities are accumulated in the filtering structure of the first butt joint pipe 10 and affect the flow of the molten liquid, first ensure that the output port at the bottom of the smelting furnace body 4 is in a valve closed state, and then control the first butt joint pipe 10 and the second butt joint pipe 17 that are connected to the smelting furnace body 4 and the booster chamber 19 to move and shrink, so that the first butt joint pipe 10 is separated from the bottom output port of the smelting furnace body 4, and the second butt joint pipe 17 is separated from the input port at the top of the booster chamber 19, and then the driving component controls the turntable 5 to rotate, and the filtering structure facing the smelting furnace body 4 and the booster chamber 19 is replaced. By quickly replacing the filter structure responsible for filtering impurities in the alloy melt, the alloy melt after hot melting can be effectively filtered through the filter structure while ensuring a certain flow rate, thereby achieving efficient filtration and purification of the alloy melt.

[0039] A valve disc 20 is slidably connected in the boosting chamber 19, and a circular hole 2001 is formed through the valve disc 20. A sealing plate 21 that cooperates with the opening and closing of the circular hole 2001 is slidably connected to the bottom of the valve disc 20. A control component for controlling the vertical sliding of the valve disc 20 is provided in the boosting chamber 19. A transmission member and an elastic member are provided at the bottom of the valve disc 20. When the valve disc 20 moves downward, the circular hole 2001 remains closed. As the valve disc 20 moves downward into place, the sealing plate 21 slides to open the circular hole 2001 under the action of the elastic member. When the valve disc 20 moves upward, the sealing plate 21 slides and gradually closes the circular hole 2001 under the action of the transmission member.

[0040] When the alloy melt after hot melting is discharged outward from the smelting furnace body 4, the valve disc 20 is controlled to move downward along the boost chamber 19, so that the input port of the boost chamber 19 is in a negative pressure state, which is beneficial to accelerate the flow rate of the alloy melt through the filtering structure and further improve the efficiency of the purification filtration of the alloy melt.

[0041] When the valve disc 20 descends, the two sealing plates 21 remain in a closed state, so that the alloy solution in the smelting furnace body 4 is sucked by the descent of the valve disc 20. When the valve disc 20 descends into place, the two sealing plates 21 will slide and open under the action of the elastic member. At this time, the alloy solution sucked above the valve disc 20 will flow downward through the valve disc 20 through the circular hole 2001, and be discharged out of the booster chamber 19 through the pipe connected to the booster chamber 19. When the valve disc 20 moves upward along the booster chamber 19, the two sealing plates 21 will move synchronously in opposite directions along the valve disc 20 under the action of the transmission member. In this process, since the circular hole 2001 is always in an open state, the upward movement of the valve disc 20 will not affect the flow of the alloy solution out of the smelting furnace body 4, until the valve disc 20 moves upward into place, the two sealing plates 21 will complete the closing, and when the valve disc 20 descends again, the alloy solution in the smelting furnace body 4 will continue to be sucked. Through the arrangement of this structure, the valve disc 20 is made to reciprocate in the vertical direction, so as to cooperate with the filtering structure to perform efficient filtering treatment on the alloy melt, thereby achieving the purpose of improving the alloy purification smelting efficiency.

[0042] Embodiment 2:

[0043] The technical solution is basically the same as that of the first embodiment, except that Figure 1-3 As shown, the component for controlling the sliding and extension of the first butt joint tube 10 and the second butt joint tube 17 includes a rotary sleeve 14 rotatably connected to the bottom of the turntable 5, and the rotary sleeve 14 is slidably sleeved on the outer side of the second butt joint tube 17, the side wall of the second butt joint tube 17 is formed with rib teeth 13, and the rotary sleeve 14 is formed with a strip groove 15 that cooperates with the sliding of the rib teeth 13, and a component for controlling the rotation of the rotary sleeve 14 is provided on the equipment frame 2.

[0044] The first butt joint tube 10 is fixed with a vertical rod slidably connected to a retaining frame 18 through a side arm. The retaining frame 18 is used to ensure that the first butt joint tube 10 can only slide vertically relative to the turntable 5, so that the second butt joint tube 17 screwed together with the first butt joint tube 10 can effectively drive the first butt joint tube 10 to move in the vertical direction when rotating.

[0045] The component for controlling the rotation of the rotary sleeve 14 includes a toothed disc 16 rotatably connected to the bottom of the turntable 5, and the toothed disc 16 is meshedly connected to the rotary sleeve 14, and a shaft 8 passing through the turntable 5 is fixed on the toothed disc 16, and a first motor 9 is installed on the equipment frame 2, and the output end of the first motor 9 is fixed to the shaft 8.

[0046] When it is necessary to control the rotation of the rotary sleeve 14 relative to the turntable 5, only the first motor 9 is started, so that the first motor 9 drives the toothed disc 16 fixed to the shaft 8 to rotate, thereby rotating the rotary sleeve 14 engaged with the toothed disc 16, and the side wall of the rotary sleeve 14 is formed with teeth that engage with the toothed disc 16.

[0047] Embodiment three:

[0048] The technical solution is basically the same as that of the first embodiment, except that Figure 1-3 A retaining ring is formed on the side wall of the first butt joint pipe 10, and a groove for sliding with the retaining ring is formed in the inner wall of the second butt joint pipe 17. When the first butt joint pipe 10 and the second butt joint pipe 17 are in a fully opened state, the retaining ring fits precisely with the end of the groove, thereby ensuring the sealing of the pipeline when the first butt joint pipe 10 and the second butt joint pipe 17 are opened to butt the smelting furnace body 4 and the booster chamber 19, which is beneficial to the safe transportation of the alloy melt.

[0049] When the rotary sleeve 14 rotates, the second butt joint tube 17 will rotate synchronously with the rotary sleeve 14 under the drive of the rib teeth 13 of the strip groove 15. Since the vertical movement distance of the second butt joint tube 17 and the first butt joint tube 10 is limited, after the rotary sleeve 14 completes the rotation, the first butt joint tube 10 and the second butt joint tube 17 will be correspondingly extended or shortened by a certain distance under the action of mutual rotation. When the first butt joint tube 10 and the second butt joint tube 17 move and shorten, they will be undocked from the output port of the smelting furnace body 4 and the input port of the booster chamber 19 respectively, which is beneficial to the subsequent rotation of the turntable 5 and the rapid switching of its position.

[0050] When the corresponding first butt joint tube 10 and second butt joint tube 17 face the smelting furnace body 4 and the boost chamber 19 as the turntable 5 rotates, the first butt joint tube 10 and second butt joint tube 17 are driven to slide and extend by controlling the rotation of the rotary sleeve 14, so that the first butt joint tube 10 and second butt joint tube 17 are respectively connected to the output port of the smelting furnace body 4 and the input port of the boost chamber 19, thereby ensuring that the alloy melt in the smelting furnace body 4 can be safely transported along the predetermined flow path when it is discharged to the outside, thereby achieving filtration and purification.

[0051] Embodiment 4:

[0052] The technical solution is basically the same as that of the first embodiment, except that Figure 1-2 The driving component includes a rotary drum 6 fixed on the turntable 5, and the rotary drum 6 is rotatably connected to the equipment frame 2, and the equipment frame 2 is provided with a first driving mechanism 7 for controlling the rotation of the rotary drum 6.

[0053] The first driving mechanism 7 is a conventional driving method in which a transmission wheel and a belt are matched to drive. A shell is fixed on the equipment frame 2, in which a transmission wheel is rotatably installed. A belt matching the transmission is provided on the outer side of the transmission wheel and the rotary drum 6. A motor for controlling the rotation of the transmission wheel is also installed on the shell. When the positions of the first butt joint pipe 10 and the second butt joint pipe 17 need to be adjusted, the first driving mechanism 7 and the first motor 9 need to be started at the same time, so that the gear plate 16 and the turntable 5 keep rotating synchronously, and then when the turntable 5 rotates, the rotary sleeve 14 keeps a stationary state relative to the turntable 5. During the rotation of the turntable 5, the first butt joint pipe 10 and the second butt joint pipe 17 keep a stable contracted state, which is conducive to switching their positions as the turntable 5 rotates.

[0054] Embodiment five:

[0055] The technical solution is basically the same as that of the first embodiment, except that Figure 2 As shown. The filtering structure includes a filter screen 11 installed in the first butt joint 10 and a ceramic composite pile 12 located below the filter screen 11. In the alloy smelting process, filtration is a key step for removing non-metallic inclusions in the melt and improving the purity and performance of the alloy. The filter screen 11 is a stainless steel wire mesh, which can purify the alloy melt and improve the quality of the alloy ingot. It not only filters most of the coarse inclusions, but also is very effective in reducing micro shrinkage pores.

[0056] The ceramic composite pile 12 is a fiber ceramic composite material, which can remain stable in the high temperature environment of the alloy melt and is not easy to react chemically with the melt, thereby ensuring the service life and filtering effect of the filter material. The fiber ceramic composite filter material usually has a high porosity, which helps to reduce the filtering resistance and improve the filtering efficiency.

[0057] Embodiment six:

[0058] The technical solution is basically the same as that of the first embodiment, except that Figure 4-Figure 6 As shown, a transverse plate 22 is fixedly provided at the bottom of the valve disc 20, and the control component includes a transmission arm 23 rotatably connected to the inner side of the boost chamber 19, the free end of the transmission arm 23 is rotatably connected to the transverse plate 22, and a second motor 24 for controlling the rotation of the transmission arm 23 is installed at the outer end of the boost chamber 19.

[0059] The transmission arm 23 is composed of two arms of equal length, one of which is rotatably connected to the inner wall of the boost chamber 19, and the other is rotatably connected to the transverse plate 22. The second motor 24 is started to control the rotation of the transmission arm 23, and the rotation of the transmission arm 23, folding or extending, drives the transverse plate 22 rotatably connected to the free end of the transmission arm 23 to drive the valve disc 20 to move in the vertical direction.

[0060] The transmission member includes a sleeve 29 slidably arranged on the inner side of the transverse plate 22, and a component driving the sleeve 29 to move. A guide rod 31 is slidably embedded inside the sleeve 29. A compression spring 32 is embedded in the sleeve 29 and abuts against the guide rod 31 upward. A guide groove 2101 is formed in the sealing plate 21 to cooperate with the sliding of the guide rod 31.

[0061] The guide groove 2101 consists of a first transverse groove, a second transverse groove and an oblique groove. The first transverse groove and the second transverse groove are vertically distributed. The end surface of the oblique groove that slides in conjunction with the guide rod 31 forms a slope that presses the guide rod 31 downward. The intersection of the oblique groove and the first transverse groove forms a stepped structure that cooperates with the rebound of the guide rod 31.

[0062] When the valve disc 20 moves downward along the boost chamber 19, the sleeve 29 will drive the guide rod 31 to slide along the first transverse groove. During this process, the two sealing plates 21 will remain stationary relative to the valve disc 20, and the circular hole 2001 will remain closed under the action of the sealing plate 21. As the valve disc 20 descends to its position, the guide rod 31 slides to the intersection of the first transverse groove and the second transverse groove. At this time, the two sealing plates 21 will slide open under the action of the elastic member, and the guide rod 31 will slide along the second transverse groove during the opening of the sealing plate 21. When the valve disc 20 moves upward along the boost chamber 19, the sleeve 29 will drive the guide rod 31 to slide along the oblique groove. The guide rod 31 will compress the inner wall of the oblique groove, driving the two sealing plates 21 to move synchronously along the valve disc 20. During this process, the guide rod 31 will squeeze the compression spring 32 downward under the pressure of the slope of the oblique groove until the two sealing plates 21 slide and close the circular hole 2001. The guide rod 31 will slide out of the oblique groove. As the deformation of the compression spring 32 is restored, the guide rod 31 will bounce back into the first transverse groove.

[0063] Through the structural arrangement of the first transverse groove, the second transverse groove and the oblique groove, when the valve disc 20 moves vertically back and forth along the booster chamber 19, the sealing plate 21 can slide orderly along the first transverse groove, the second transverse groove and the oblique groove, thereby ensuring the valve disc 20's suction operation on the alloy melt.

[0064] The components that drive the sliding sleeve 29 to move include a rotating shaft 28 rotatably connected to the inner side of the cross plate 22, and a fitting that drives the rotating shaft 28 to rotate. The sliding sleeve 29 is slidably mounted on the outer side of the rotating shaft 28. A protrusion 30 is formed in the inner wall of the sliding sleeve 29, and a sliding rail 33 that cooperates with the protrusion 30 to slide is formed on the side wall of the rotating shaft 28.

[0065] The slide rail 33 is a spiral structure. When the rotary shaft 28 rotates, the slide rail 33 acts on the protrusion 30 through its spiral inner wall, driving the sliding sleeve 29 fixed to the protrusion 30 to slide horizontally along the bottom of the sealing plate 21.

[0066] The components that drive the rotating shaft 28 to rotate include a driving wheel 25 and a driven wheel 26 that are rotatably connected to the inner side of the cross plate 22. The outer meshing sleeves of the driving wheel 25 and the driven wheel 26 are provided with a chain 27. The driving wheel 25 is coaxially fixed with the output end of the transmission arm 23, and the driven wheel 26 is coaxially fixed with the rotating shaft 28.

[0067] When the horizontal plate 22 drives the valve disc 20 to move in the vertical direction under the action of the transmission arm 23, the driving wheel 25 fixed to the free end of the transmission arm 23 will rotate along the horizontal plate 22, and the driven wheel 26 will rotate synchronously with the driving wheel 25 under the action of the chain 27. Both the driving wheel 25 and the driven wheel 26 are toothed discs 16 meshed with the chain 27.

[0068] Embodiment seven:

[0069] The technical solution is basically the same as that of the first embodiment, except that Figure 5 As shown, the elastic member includes a slider 34 fixed to the side end of the sealing plate 21 , a slide groove cooperating with the slide groove 34 is formed in the valve disc 20 , and a return spring 35 elastically abutting between the two sliders 34 is arranged in the slide groove.

[0070] When the guide rod 31 slides with the sliding sleeve 29 to the intersection of the first transverse groove and the second transverse groove, the slider 34 will drive the sealing plate 21 to slide and open under the action of the return spring 35 .

[0071] Specifically, a smelting method of a high-temperature alloy purification smelting furnace comprises the following steps:

[0072] S1, putting the metal material into the smelting furnace body 4 for smelting, during which the metal material is protected by controlling the atmosphere composition and flow rate in the furnace through the protective atmosphere furnace 3;

[0073] S2, opening the electric valve at the bottom output port of the smelting furnace body 4, so that the alloy melt in the smelting furnace body 4 is discharged into the first butt joint pipe 10, and the impurities in the alloy melt are filtered and purified by the filtering structure in the first butt joint pipe 10;

[0074] S3. By controlling the reciprocating movement of the valve disc 20 in the vertical direction, the speed of the alloy melt flowing through the filtering structure is accelerated. After the alloy solution is filtered, it flows into the pressurizing chamber 19 and is then discharged to the outside.

[0075] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
