Description

Technical Field

[0001] This invention relates to the field of metal ingot production technology, and in particular to a stirring device and method for producing suspended lifting metal ingots. Background Technology

[0002] When producing metal ingots such as zinc, aluminum, and lead, there may be compositional segregation (such as uneven distribution of different elements) and uneven melt temperature, which can lead to differences in solidification structure (such as the coexistence of coarse and fine grains). Therefore, it is necessary to use a stirring device to break up local concentration differences through forced convection, ensuring that the chemical composition is evenly distributed in the melt. At the same time, stirring can also reduce the temperature gradient by mixing high-temperature and low-temperature regions, creating conditions for uniform solidification. This is especially important for producing high-precision, high-performance metal ingots (such as alloys for aerospace). Existing stirring devices for metal ingot production are mainly based on mechanical stirring and electromagnetic stirring. The former uses a rotary stirrer (such as a paddle or spiral) to generate forced convection and shear force to achieve uniform mixing, while the latter uses an alternating magnetic field to drive the non-contact movement of the melt to refine grains and improve microstructure. Although electromagnetic stirring structures have become the mainstream technology due to their advantages such as non-contact stirring, precise and controllable parameters, and strong scalability, especially in continuous casting processes, mechanical stirring structures are still active in small-batch production or auxiliary processes in specific scenarios due to their advantages such as strong stirring force, wide applicability, simple structure and low cost, flexible operation and easy maintenance. In existing mechanical stirring structures used for metal ingot production, the stirring rods or blades need to be in long-term contact with the molten metal during raw material stirring. Since the temperature of the molten metal is extremely high, the stirring blades and rods must withstand the high-temperature environment for a long time, which leads to a decrease in material strength, accelerated creep, and even softening and deformation. At the same time, because the stirring rods and blades are in long-term contact with the high-temperature molten metal, the metal elements (such as aluminum) in the molten metal may react chemically with the stirring materials to form low-melting-point compounds or brittle phases, which leads to the deterioration of material properties. As a result, the stirring elements in existing mechanical stirring structures have a short service life and require frequent maintenance and replacement. Summary of the Invention

[0003] The purpose of this invention is to provide a floating lifting stirring device and method for producing metal ingots. The mechanical stirring mechanism allows the stirring body to alternately contact and stir, avoiding prolonged contact between the stirring body and the molten metal. This greatly reduces the contact time between the stirring body and the molten metal without affecting the normal stirring effect, thereby increasing the service life of the stirring body.

[0004] To achieve the above objectives, the present invention provides a suspended lifting stirring device for producing metal ingots, including a melting cylinder, a feeding device, and a discharging mechanism. The feeding device is installed on one side of the melting cylinder, the discharging mechanism is located at the bottom of the melting cylinder, and the device also includes a stirring component. The agitation assembly includes a shielding cover, an agitating rotating cover, a rotating cover drive mechanism, mounting components, a tilting platform, a reciprocating steering component, and a turbulence component. The shielding cover is disposed on the top of the molten metal cylinder. The agitating rotating cover is rotatably mounted on the shielding cover. The rotating cover drive mechanism is mounted on the shielding cover and is used to drive the agitating rotating cover. Two mounting components are respectively fixedly mounted on both sides of the agitating rotating cover. The tilting platform is rotatably mounted on the bottom of each mounting component. The reciprocating steering component is connected to the mounting component and is used to drive the tilting platform at the bottom of the mounting component. The turbulence component is disposed on each tilting platform and is used to agitate the molten metal inside the molten metal cylinder.

[0005] The reciprocating steering component includes a flipping gear, a connecting gear, a gear chain, a linkage component, and a repeating component. Each flipping platform has a rotating shaft that mates with the mounting component, and the flipping gear is fixedly mounted on the shaft within the corresponding mounting component. Each mounting component has a connecting gear rotatably mounted inside it. The flipping gear and connecting gear within each mounting component are connected via the gear chain. Each mounting component has a linkage component, and the repeating component is connected to the shielding cover. The linkage component, in conjunction with the repeating component, drives the connecting gear.

[0006] The stirring component includes a rotating frame, a stirring inclined rod, and a rotating component. The rotating frame is rotatably mounted on the flipping platform. The stirring inclined rod is mounted on the rotating frame. Each flipping platform is provided with the rotating component, which drives the corresponding stirring inclined rod to rotate when the corresponding flipping platform rotates.

[0007] The linkage component includes a guide rail side platform, an external gear, and a sliding rack frame. The guide rail side platform is fixedly installed on one side of the mounting component. The external gear is fixedly connected to the connecting gear installed on the corresponding mounting component. The sliding rack frame is slidably connected to the guide rail side platform, and the sliding rack frame meshes with the external gear through an inner rack.

[0008] The repetitive component includes a guide groove outer cylinder and an adapter guide. The guide groove outer cylinder is fixedly installed on the top of the shielding cover. Each sliding rack frame is equipped with an adapter guide on its side, and the adapter guide cooperates with the annular guide groove provided on the guide groove outer cylinder.

[0009] The rotating component includes a threaded connecting sleeve, a sliding platform, a threaded rod, and an inner arc guide groove disc. The threaded connecting sleeve is fixedly mounted on the rotating frame; the sliding platform is slidably mounted on the flipping platform; the threaded rod is threadedly connected to the threaded connecting sleeve and fixedly mounted on one side of the sliding platform; the inner arc guide groove disc is fixedly mounted on the bottom of the stirring cover, and the inner oblique arc groove of the inner arc guide groove disc cooperates with the protruding frustum on the side of the sliding platform.

[0010] The repetitive component further includes an upper synchronous frame, an upper moving lead screw, and a drive motor. The upper synchronous frame is slidably mounted on the outer cylinder of the guide groove. The upper moving lead screw is threadedly connected to the upper synchronous frame and rotatably mounted on the shielding cover. The output shaft of the drive motor is connected to the upper moving lead screw, and the drive motor is fixedly mounted on the shielding cover.

[0011] The agitation assembly further includes a sealing guide sleeve, a fixed loading frame, a pushing frame, and an adjusting component. The sealing guide sleeve is fixedly installed at the bottom of the shielding cover; the fixed loading frame is fixedly installed on the molten material cylinder; the pushing frame is slidably installed on the fixed loading frame; and the adjusting component is connected to the outer cylinder of the guide groove and is used to adjust the position of the shielding cover and the corresponding mechanism provided on the shielding cover.

[0012] The adjusting component includes a sliding guide column, a lifting cylinder, and a screw lateral movement mechanism. The sliding guide column is slidably connected to the pushing frame and is fixedly installed on the outer cylinder of the guide groove. The output end of the lifting cylinder is connected to the outer cylinder of the guide groove and is fixedly installed on the pushing frame. The screw lateral movement mechanism is connected to the fixed loading frame and is used to drive the pushing frame.

[0013] A stirring method for producing suspended lifting metal ingots, employing the aforementioned stirring device, includes the following steps. The molten metal is introduced into the melting cylinder through the feeding device, and then the rotating cover is driven by the rotating cover drive mechanism on the cover to rotate. The rotation of the agitator cover causes the two mounting parts mounted on the agitator cover to rotate. When the two mounting components rotate via the agitator cover, the flipping platform provided with the mounting components will rotate alternately under the action of the reciprocating steering component; The alternating rotation of the two flip-top platforms drives the stirring components set on the corresponding flip-top platforms to rotate. When one of the stirring components rotates downward and unfolds, the other stirring component rotates upward and retracts, so that the molten metal inside the melting cylinder can be stirred by the rotating stirring cover in conjunction with the downward-unfolding stirring component. By utilizing the alternating rotation of the two sets of stirring components, the two sets of stirring components alternately cooperate with the molten metal inside the melting cylinder, thereby shortening the contact time between a single stirring component and the molten metal and ensuring the service life of the corresponding stirring main structure.

[0014] This invention discloses a suspended lifting stirring device and method for producing metal ingots. In practical use, molten metal is introduced into the melting cylinder through the feeding device. Then, the rotating cover on the shielding cover is driven to rotate by the rotating cover driving mechanism. The rotation of the rotating cover drives two mounting members mounted on it to rotate. When the two mounting members rotate through the rotating cover, the flipping platforms of the mounting members rotate alternately under the action of the reciprocating steering member. The alternating rotation of the two flipping platforms drives the turbulence members mounted on the corresponding flipping platforms to rotate. When one of the turbulence members rotates downward and unfolds, the other turbulence member... The components then rotate upwards and retract, allowing the turbulent components to rotate in conjunction with the rotating agitator cover to agitate the molten metal inside the molten cylinder. By alternating the rotation of the two sets of turbulent components, the two sets of turbulent components alternately engage with the molten metal inside the molten cylinder, thereby shortening the contact time between a single turbulent component and the molten metal. This ensures the service life of the corresponding agitator structure and enables the agitator to alternately contact and agitate through the provided mechanical stirring mechanism, avoiding prolonged contact between the agitator and the molten metal. This significantly reduces the contact time between the agitator and the molten metal without affecting the normal agitation effect, thus increasing the service life of the agitator.

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Please see Figures 1 to 10This invention provides a suspended lifting stirring device and method for producing metal ingots: It includes a melting cylinder 101, a feeding device 102, a discharging mechanism 103, and a stirring assembly. The stirring assembly includes a shielding cover 104, a stirring rotating cover 105, a rotating cover driving mechanism 106, a mounting component 107, a flipping platform 108, a reciprocating steering component, and a turbulence component. The reciprocating steering component includes a flipping gear 201, a connecting gear 202, a gear chain 203, a linkage component, and a repetitive component. The turbulence component includes a rotating frame 301, a stirring inclined column 302, and a rotating component. The linkage component includes a guide rail side platform 401, an external gear 402, and a sliding rack frame 403. The repetitive component includes a guide groove outer cylinder 501 and an adapting guide 502. The rotating component includes a connecting threaded hole sleeve 601 and a sliding table 60. 2. The threaded rod 603 and the inner arc guide groove disk 604, the reciprocating component also includes an upper synchronous frame 503, an upper moving screw 504 and a drive motor 505. The above solution solves the problem that in the existing mechanical stirring structure for metal ingot production, when stirring raw materials, the stirring rod or stirring blade needs to be in long-term contact with the molten metal. Since the temperature of the molten metal is extremely high, the stirring blade and stirring rod need to withstand the high temperature environment for a long time, which leads to a decrease in material strength, accelerated creep, and even softening and deformation. At the same time, because the stirring rod and stirring blade are in long-term contact with the high-temperature molten metal, the metal elements (such as aluminum) in the molten metal may react chemically with the stirring material to form low-melting-point compounds or brittle phases, which leads to the deterioration of material properties. This results in a short service life of the stirring elements in the existing mechanical stirring structure, which requires frequent maintenance and replacement.

[0031] Furthermore, the feeding device 102 is installed on one side of the molten material cylinder 101, the discharging mechanism 103 is located at the bottom of the molten material cylinder 101, the shielding cover 104 is located at the top of the molten material cylinder 101, the stirring rotating cover 105 is rotatably installed on the shielding cover 104, the rotating cover driving mechanism 106 is installed on the shielding cover 104 and is used to drive the stirring rotating cover 105, the two mounting parts 107 are respectively fixedly installed on both sides of the stirring rotating cover 105, the bottom of each mounting part 107 is rotatably installed with the flipping platform 108, the reciprocating steering component is connected to the mounting part 107 and is used to drive the flipping platform 108 at the bottom of the mounting part 107, and each flipping platform 108 is provided with the agitating component for agitating the molten metal inside the molten material cylinder 101.

[0032] Specifically, the feeding device 102 guides and adds the molten metal by cooperating with the external conductive structure, while the discharging mechanism 103 is used to discharge the molten metal inside the molten metal cylinder 101.

[0033] The top of the molten material cylinder 101 is open, and a shielding cover 104 is provided on the top of the molten material cylinder 101. The stirring cover 105 provided on the shielding cover 104 is driven by the cover driving mechanism 106. The cover driving mechanism 106 consists of a gear set and a motor that drives the gear set. The stirring cover 105 is driven by the meshing between the gears, so that the stirring cover 105 can rotate on the shielding cover 104.

[0034] In actual use, the molten metal is introduced into the melting cylinder 101 through the feeding device 102. Then, the rotating cover drive mechanism 106 on the shielding cover 104 drives the agitating cover 105 to rotate. The rotation of the agitating cover 105 drives the two mounting members 107 mounted on the agitating cover 105 to rotate. When the two mounting members 107 rotate through the agitating cover 105, the flipping platform 108 on the mounting members 107 will rotate alternately under the action of the reciprocating steering member. The alternating rotation of the two flipping platforms 108 drives the turbulence member mounted on the corresponding flipping platform 108 to rotate. When one of the turbulence members rotates downward and unfolds, the other... The aforementioned stirring components will then rotate upwards and retract, allowing the molten metal inside the molten metal cylinder 101 to be stirred by the rotation of the stirring cover 105, which is then rotated downwards. By using two sets of stirring components rotating alternately, the two sets of stirring components alternately engage with the molten metal inside the molten metal cylinder 101, thereby shortening the contact time between a single stirring component and the molten metal. This ensures the service life of the corresponding stirring main structure and enables the stirring main body to alternately contact and stir through the provided mechanical stirring mechanism, avoiding prolonged contact between the stirring main body and the molten metal. This greatly reduces the contact time between the corresponding stirring main body and the molten metal without affecting the normal stirring effect, thereby increasing the service life of the corresponding stirring main body.

[0035] Furthermore, each of the flipping platforms 108 and the mounting members 107 has a rotating shaft fixedly mounted with a flipping gear 201, located within the corresponding mounting member 107; each mounting member 107 has a connecting gear 202 rotatably mounted inside; the flipping gear 201 and the connecting gear 202 inside each mounting member 107 are connected by a gear chain 203; each mounting member 107 has a linkage component, and the repetitive component is connected to the shielding cover 104, and the linkage component cooperates with the repetitive component to drive the connecting gear 202.

[0036] Furthermore, the guide rail side platform 401 is fixedly installed on one side of the mounting member 107; the external gear 402 is fixedly connected to the connecting gear 202 installed on the corresponding mounting member 107; the sliding rack frame 403 is slidably connected to the guide rail side platform 401, and the sliding rack frame 403 meshes with the external gear 402 through the provided inner rack.

[0037] Furthermore, the outer cylinder 501 of the guide groove is fixedly installed on the top of the shielding cover 104; each of the sliding rack brackets 403 is equipped with the adapter guide 502 on its side, and the adapter guide 502 cooperates with the annular guide groove provided on the outer cylinder 501 of the guide groove.

[0038] Furthermore, the upper synchronous frame 503 is slidably mounted on the outer cylinder 501 of the guide groove; the upper moving screw 504 is threadedly connected to the upper synchronous frame 503 and rotatably mounted on the shielding cover 104; the output shaft of the drive motor 505 is connected to the upper moving screw 504, and the drive motor 505 is fixedly mounted on the shielding cover 104.

[0039] In this embodiment, each mounting component 107 is provided with a set of the flip gear 201, the connecting gear 202, and the toothed chain 203. The toothed chain 203 enables the flip gear 201 and the connecting gear 202 provided in the same mounting component 107 to rotate synchronously. Each connecting gear 202 is provided with an external gear 402 for driving. The external gear 402 cooperates with the inner rack of the sliding rack frame 403.

[0040] The sliding rack frame 403 is provided with a corresponding guide groove that matches the guide rail side platform 401 provided on the side of the mounting component 107. When the sliding rack frame 403 slides on the guide rail side platform 401, the inner rack of the sliding rack frame 403 can drive the external gear 402 to rotate, thereby driving the connecting gear 202. The connecting gear can drive the flip gear 201 and the flip platform 108 to rotate through the gear chain 203.

[0041] The above structure utilizes the up-and-down movement of the sliding rack frame 403 to drive the flipping platform 108, and then uses the rotation of the flipping platform 108 to unfold and retract the corresponding turbulent components.

[0042] Since the two turbulent components need to rotate alternately, the two sliding racks 403 on the two mounting members 107 need to move up and down alternately. The sides of the two mounting members 107 cooperate with the annular guide groove of the guide groove outer cylinder 501 through the adapter guide 502. The adapter guide 502 is provided with a corresponding rolling sleeve in the annular guide groove cooperation part of the guide groove outer cylinder 501 so that the cooperation between the adapter guide 502 and the guide groove outer cylinder 501 is smoother.

[0043] The annular guide groove of the outer cylinder 501 is divided into two connected parts, left and right, with the two sides being two guide grooves, one gently descending and the other sharply ascending. Since the outer cylinder 501 is fixed on the shielding cover 104, when the stirring cover 105 drives the mounting parts 107 on both sides to rotate, the sliding rack brackets 403 on the sides of the two mounting parts 107 will drive the corresponding adapter guides 502 to rotate on the annular guide groove of the outer cylinder 501.

[0044] When the adapter guide 502 rotates relative to the outer cylinder 501 of the guide groove, the adapter guide 502 will be guided by the annular guide groove of the outer cylinder 501 of the guide groove, thereby realizing different drives for the two sliding rack frames 403. When the sliding rack frame 403 on one side continues to descend, the sliding rack frame 403 on the other side may start to rise. In this way, by utilizing the design of the annular guide groove, when the stirring cover 105 rotates, the sliding rack frames 403 on both sides can be driven accordingly, so that the two sets of stirring components can alternately rotate and unfold and rotate and retract.

[0045] It should be noted that, due to the transmission of gears and chains in this design, when the sliding rack frame 403 moves downward, the corresponding flipping platform 108 will drive the turbulent component to rotate downward and unfold. When the sliding rack frame 403 moves upward, the corresponding flipping platform 108 will drive the turbulent component to rotate upward and retract. Therefore, in designing the annular guide groove, by adopting a slow downward and rapid upward setting, the turbulent component on one side can slowly descend along with the rotation of the turbulent cover 105 when unfolding downward. The rotational path of the turbulent component during unfolding, combined with the rotation of the turbulent cover... The rotation of 105 can perform compound agitation on the molten metal inside the molten metal cylinder 101, enabling the molten metal to be mixed and agitated more evenly and comprehensively. The upward setting allows the agitating component to be quickly retrieved when it is rotated upwards for recycling, and then the corresponding agitating component is kept in the recycling state until another agitating component begins to be recycled. This greatly reduces the contact time between a single agitating component and the molten metal, ensuring that the molten metal is agitated while avoiding excessive contact time between a single agitating component and the molten metal.

[0046] The guide groove outer cylinder 501 is also provided with the upper top synchronous frame 503. The upper top synchronous frame 503 has a corresponding threaded hole side platform on its side. The upper moving screw 504 is convenient to cooperate with the threaded hole side platform on the side of the upper top synchronous frame 503. The upper moving screw 504 is driven by the drive motor 505. When the drive motor 505 drives the upper moving screw 504 to rotate, the upper moving screw 504 can drive the upper top synchronous frame 503 to move upward. The upward movement of the upper top synchronous frame 503 can lift the matching guides 502 provided on the sides of the two sliding rack frames 403, so that the sliding rack frames 403 on both sides can move upward. In this way, the two sets of stirring components can be rotated and retrieved together. After the metal melt is stirred, the two stirring components can be retrieved together, avoiding unnecessary excessive contact between the stirring components and the metal melt.

[0047] Furthermore, the rotating frame 301 is rotatably mounted on the flipping platform 108; the stirring inclined rod 302 is mounted on the rotating frame 301; each flipping platform 108 is provided with the self-rotating component, which drives the corresponding stirring inclined rod 302 to rotate when the corresponding flipping platform 108 rotates.

[0048] Furthermore, the connecting threaded hole sleeve 601 is fixedly installed on the rotating frame 301; the sliding table 602 is slidably installed on the flipping platform 108; the threaded rod 603 is threadedly connected to the connecting threaded hole sleeve 601 and fixedly installed on one side of the sliding table 602; the inner arc guide groove disk 604 is fixedly installed on the bottom of the stirring cover 105, and the inner oblique arc groove provided by the inner arc guide groove disk 604 cooperates with the protruding frustum on the side of the sliding table 602.

[0049] In this embodiment, the stirring inclined rod 302 has a rod-shaped structure and is provided with multiple sets of downward-sloping inclined rods. The rod-shaped structure design of the stirring inclined rod 302 can reduce the sharp angles of the stirring element edge and reduce wear caused by molten liquid scouring. At the same time, the outer surface of the stirring inclined rod 302 is also coated with ceramic material (such as alumina or zirconium oxide) to form a corrosion-resistant and wear-resistant protective layer, so that the molten metal inside the melting cylinder 101 can be stirred by the downward rotation and rotation of the stirring inclined rod 302.

[0050] The rotation of the flip-top platform 108 at the bottom of the mounting component 107 drives the agitating inclined rod 302 to rotate downwards and unfold. The agitating inclined rod 302 is mounted on the rotating frame 301, which can rotate on the flip-top platform 108. The connecting threaded hole sleeve 601 is fixed inside the rotating frame 301. The connecting threaded hole sleeve 601 cooperates with the threaded rod 603 provided on the sliding table 602. The sliding table 602 cooperates with the inner inclined arc groove of the inner arc guide plate 604 through the protruding frustum on the side.

[0051] When the flip-top platform 108 rotates at the bottom of the mounting component 107, the sliding platform 602 provided on the flip-top platform 108 will cooperate with the inner arc guide groove disk 604 through the protruding truncated cone on the side, thereby driving the sliding platform 602 to move. This causes the threaded rod 603 of the sliding platform 602 to be displaced relative to the connecting threaded hole sleeve 601. At this time, the threaded rod 603 cannot rotate. Therefore, under the engagement of the threads, the connecting threaded hole sleeve 601 will drive the rotating frame 301 and the stirring inclined column 302 to rotate, so that the stirring inclined column 302 can rotate on its own axis while rotating downwards, resulting in better stirring of the molten metal inside the melting cylinder 101.

[0052] This application uses a mechanical linkage structure to drive and control the agitation structure, which can greatly reduce the complexity of the control system and also avoid the use of electrical components as much as possible. This is because the overall temperature is high when agitating molten metal, and using too many electrical components can easily lead to frequent maintenance due to the long-term high-temperature environment.

[0053] Preferably, the agitation assembly provided by the present invention further includes a sealing guide sleeve 701, a fixed loading frame 702, a pushing frame 703, and an adjusting component, wherein the adjusting component includes a sliding guide post 801, a lifting cylinder 802, and a lead screw lateral movement mechanism 803.

[0054] Furthermore, the sealing guide sleeve 701 is fixedly installed at the bottom of the shielding cover 104; the fixed loading frame 702 is fixedly installed on the melting cylinder 101; the pushing frame 703 is slidably installed on the fixed loading frame 702; the adjusting component is connected to the guide groove outer cylinder 501 and is used to adjust the position of the shielding cover 104 and the corresponding mechanism provided on the shielding cover 104.

[0055] Furthermore, the sliding guide post 801 is slidably connected to the pushing frame 703 and fixedly installed on the outer cylinder 501 of the guide groove; the output end of the lifting cylinder 802 is connected to the outer cylinder 501 of the guide groove, and the lifting cylinder 802 is fixedly installed on the pushing frame 703; the lead screw side-shifting mechanism 803 is connected to the fixed loading frame 702 and is used to drive the pushing frame 703.

[0056] In this embodiment, the sealing guide sleeve 701 is disposed at the bottom of the shielding cover 104. The sealing guide sleeve 701 can be used to seal the top of the molten metal cylinder 101, preventing the molten metal inside the molten metal cylinder 101 from being affected by the external environment.

[0057] The outer cylinder 501 of the guide groove is slidably connected to the pusher frame 703 through the sliding guide post 801 set at the top. The top of the outer cylinder 501 of the guide groove is also provided with the lifting cylinder 802 for driving. The pusher frame 703 is driven by the lead screw side-moving mechanism 803. The lead screw side-moving mechanism 803 is composed of a lead screw and a motor. The driving principle of the lead screw side-moving mechanism 803 is the same as that of the upward lead screw 504 and the drive motor 505.

[0058] The lifting cylinder 802 drives the outer cylinder 501 of the guide groove to move upward, which in turn drives the shielding cover 104 and the corresponding structure installed on the shielding cover 104 to move upward. Finally, the shielding cover 104 and the corresponding structure installed on the shielding cover 104 are pulled out from the melting cylinder 101. Then, the screw lateral movement mechanism 803 drives the pushing frame 703 to move laterally on the fixed loading frame 702, thereby moving the shielding cover 104 and the corresponding structure installed on the shielding cover 104 from above the melting cylinder 101, so that the operator can replace and maintain the corresponding structure installed on the shielding cover 104.

[0059] When lifting the shielding cover 104 and the corresponding structure installed on the shielding cover 104, the operator can first drive the upper synchronous frame 503 to move upward through the upward moving screw 504 and the drive motor 505, so as to retract the two sets of corresponding stirring structures in advance, which greatly reduces the subsequent lifting height and makes the transfer of the corresponding structure installed on the shielding cover 104 more efficient.

[0060] Please see Figure 11 A stirring method for producing suspended lifting metal ingots, employing the aforementioned stirring device, includes the following steps. S1: The molten metal is introduced into the melting cylinder 101 through the feeding device 102, and then the rotating cover 105 is driven to rotate by the rotating cover drive mechanism 106 on the cover 104. S2: The rotation of the stirring cover 105 drives the two mounting parts 107 disposed on the stirring cover 105 to rotate; S3: When the two mounting pieces 107 rotate through the stirring cover 105, the flipping platform 108 provided on the mounting piece 107 will rotate alternately under the action of the reciprocating steering component; S4: The alternating rotation of the two flip-top platforms 108 drives the stirring components set on the corresponding flip-top platforms 108 to rotate. When one of the stirring components rotates down and unfolds, the other stirring component rotates up and retracts, so that the molten metal inside the melting cylinder 101 can be stirred by the rotation of the stirring cover 105 in conjunction with the downward-rotating stirring component. S5: By utilizing the alternating rotation of the two sets of stirring components, the two sets of stirring components alternately cooperate with the molten metal inside the molten metal cylinder 101, thereby shortening the contact time between a single stirring component and the molten metal and ensuring the service life of the corresponding stirring main structure.
