Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bulk amorphous alloy technology, specifically relating to an amorphous alloy continuous casting device. Background Technology
[0002] In the field of modern materials science and engineering, amorphous alloys, with their excellent mechanical properties, corrosion resistance, and processing performance, have been widely used in high-end manufacturing fields such as electronics and precision machinery. As downstream application markets continue to demand higher precision, performance stability, and production efficiency from amorphous alloy products, the technical level and quality control capabilities of the master alloy preparation process, which forms the basis for amorphous alloy product manufacturing, have become key factors restricting the industry's development.
[0003] Currently, the mainstream manufacturing process for amorphous alloy master alloys in the industry generally adopts a three-stage production model of "vacuum melting furnace melting - forming - mechanical crushing". Specifically, this process first involves melting the metal raw materials at high temperature in a vacuum melting furnace to form a homogeneous alloy melt; then, the melt is poured into a specific mold to cool and form a block or strip-shaped master alloy billet; finally, the billet is crushed into granular raw materials that meet the requirements of subsequent die-casting processes using mechanical crushing equipment such as jaw crushers and ball mills. However, this traditional process suffers from many insurmountable technical defects in actual production, seriously affecting the quality of the master alloy and production efficiency. Specific problems are as follows: Firstly, the master alloy particles have a high oxygen content and are easily contaminated and hygroscopic. During the mechanical crushing process, the intense collisions and friction between the blocky master alloy billet and the crushing equipment components generate a large amount of metal debris. Simultaneously, wear impurities from the equipment itself may mix into the granular raw material, leading to a decrease in raw material purity. More importantly, the crushing process must be carried out in an open or semi-open environment, where oxygen and moisture in the air easily come into contact with the freshly crushed surface, causing oxidation of the particle surface. Furthermore, the specific surface area of the granular raw material increases significantly, further enhancing the probability of moisture absorption. These problems directly lead to defects such as porosity, inclusions, and cracks in subsequent die-casting processes, significantly increasing the product defect rate and production costs.
[0004] Secondly, the process is cumbersome, time-consuming, and energy-intensive. The three-stage production model requires the sequential completion of three independent processes: smelting, forming, and crushing. Each process requires separate equipment, space, and operating time, which not only prolongs the overall production cycle and reduces production efficiency but also leads to high equipment investment and operating costs. Furthermore, the smelting process consumes a large amount of electricity to maintain the high-temperature environment, the cooling process of the formed billet also wastes energy, and the crushing process also consumes a significant amount of energy, contradicting the current manufacturing industry's pursuit of "high efficiency, energy saving, and green" development principles.
[0005] In summary, existing amorphous alloy master alloy preparation processes have significant shortcomings in both quality control and production efficiency, failing to meet the downstream industries' demands for high-quality master alloy raw materials and efficient production. Therefore, developing an amorphous alloy continuous casting device that can effectively simplify the process, reduce energy consumption, significantly improve master alloy purity, and reduce oxidation and moisture absorption problems has become a critical technical issue urgently needing to be addressed in the field of amorphous alloy materials. This is of great significance for promoting technological upgrading and sustainable development in the industry. Summary of the Invention
[0006] The purpose of this invention is to provide an amorphous alloy continuous casting device, which aims to solve the technical problems existing in the current amorphous master alloy preparation process.
[0007] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: This utility model provides an amorphous alloy continuous casting device, characterized in that it includes a sealed and connected vacuum melting chamber and a vacuum casting chamber, as well as a continuous casting mechanism. A melting and casting partition door is provided between the vacuum melting chamber and the vacuum casting chamber. The vacuum melting chamber is externally connected to a vacuum pumping system for maintaining the vacuum environment inside the chamber. The top of the vacuum melting chamber is detachably and sealed with a furnace cover. The lower part of the furnace cover is integrated with a feeding chamber for temporarily storing amorphous alloy raw materials. The bottom of the feeding chamber is provided with a feeding port for feeding materials into the chamber. A melting mechanism for melting amorphous alloy raw materials is provided directly below the feeding port. A filtering mechanism for filtering molten raw materials is installed directly below the melting mechanism. A movable trough is provided in the vacuum casting chamber along the horizontal direction. The movable trough is connected to the power mechanism and can reciprocate linearly along the connection direction between the vacuum melting chamber and the vacuum casting chamber under the drive of the power mechanism. The trough cavity is used to receive molten amorphous alloy raw materials conveyed by the filtration mechanism. The continuous casting mechanism includes a casting cavity located below the moving trough, a casting head that is movably connected to the discharge end of the casting cavity, and a casting seat fixedly located at the end of the casting head away from the casting cavity.
[0008] The amorphous alloy continuous casting device of this utility model achieves significant technical effects through multi-structure synergy: Firstly, the vacuum melting chamber and vacuum casting chamber are sealed and connected, and in conjunction with the vacuum pumping system, a high vacuum environment can be maintained throughout the entire melting and casting process, isolating air impurities and preventing raw material oxidation. Furthermore, the melting and casting partition door between the two chambers can achieve independent vacuum control, ensuring vacuum stability during the melting and casting stages and improving product purity and mechanical properties. Secondly, the feed chamber integrated under the detachable furnace cover at the top of the vacuum melting chamber allows for pre-storage of raw materials and direct feeding through the feed inlet directly opposite the melting mechanism, eliminating traditional cumbersome operations. Simultaneously, the filtration mechanism below the melting mechanism ensures that molten raw materials can enter the casting chamber... First, pre-process filtration removes inclusions, reducing product defects and improving raw material utilization, achieving integrated convenient feeding, efficient smelting, and impurity filtration. Second, the moving trough in the vacuum casting chamber, driven by a power mechanism, can reciprocate linearly along the direction connecting the two chambers. It can flexibly adjust the raw material receiving position and speed according to needs, avoiding the accumulation of molten raw materials or uneven cooling. Combined with the casting chamber, movable casting head, and fixed casting seat in the continuous casting mechanism, it can stably pull and shape amorphous alloys, precisely control the casting speed and cooling rhythm, reduce cracks and deformation problems during solidification, and ensure product dimensional uniformity and performance stability. It is suitable for the production of high-purity, high-quality amorphous alloy products.
[0009] Furthermore, the melting mechanism includes a melting crucible for holding amorphous alloy raw materials, and an induction heating coil surrounding the melting crucible for induction heating and melting the raw materials inside the crucible. The induction heating coil is connected to a robotic arm, which can drive the induction heating coil to synchronously rotate the melting crucible, so that the molten amorphous alloy liquid inside the crucible is poured directionally into the filtration mechanism below through the opening of the melting crucible. This melting mechanism adopts a surrounding melting method, which results in more uniform heating during the melting process. At the same time, it also realizes automated production through mechanical devices, reducing manual intervention and improving production efficiency.
[0010] Furthermore, the filtration mechanism is a silicon carbide filter screen with a mesh size of 70-300 μm, and the feed end of the silicon carbide filter screen is positioned below the opening of the melting crucible. The silicon carbide filter screen maintains structural stability in the high-temperature environment of the amorphous alloy melt, preventing the filter screen itself from softening at high temperatures or reacting chemically with the melt to generate impurities. Its excellent wear resistance extends the filter screen's service life and reduces equipment maintenance costs. The designed mesh size accurately filters out common harmful impurities in the melt, such as metal oxides and unmelted particles (these impurities are often larger than 300 μm), while ensuring smooth flow of the melt. This avoids the melt flow rate being too slow due to excessively small pores, causing cooling and solidification that clogs the filter screen, or the impurities leaking out due to excessively large pores, affecting product quality. Furthermore, a molten flow channel for guiding the flow of molten metal is provided through the bottom of the moving tank. The inlet end of the molten flow channel is located at the bottom of the moving tank cavity, and the outlet end extends downward. Driven by a power mechanism, the moving tank can move to the initial position directly below the filtration mechanism to receive the molten amorphous alloy filtered by the filtration mechanism. After all the molten metal has been injected into the moving tank, the power mechanism drives the moving tank to the casting position directly above the casting cavity. At this time, the outlet end of the molten flow channel is sealed and connected to the inlet of the casting cavity, allowing the molten amorphous alloy in the moving tank to flow directionally into the casting cavity along the molten flow channel to complete the casting process. The continuous casting mechanism in this invention uses a fully automated process for molten metal transportation and casting, improving the automation level of the process.
[0011] Furthermore, the bottom of the moving trough is also equipped with a set of moving wheels for auxiliary movement. The moving wheel set includes at least two sets of rollers symmetrically distributed along the direction of movement of the moving trough, each roller being rotatably connected to the bottom of the moving trough via an axle. The bottom of the vacuum melting chamber and the vacuum casting chamber are equipped with guide rails adapted to the movement trajectory of the moving wheel set, allowing the moving wheel set to roll along the guide rails. This cooperative structure of the moving wheel set and guide rails allows the moving trough to smoothly switch positions under the drive of the power mechanism, avoiding deviation or jamming during movement; it also reduces friction between the moving trough and the bottom of the chamber, reducing equipment wear, extending service life, and further ensuring the stability of the molten metal conveying process.
[0012] Furthermore, the casting head is sized to match the discharge end of the casting cavity, and the two are connected via a detachable sealing structure. The casting base is connected to the drive system and moves at a constant speed along the axis of the casting head during casting traction. This allows the casting head to move axially along the discharge end of the casting cavity under the traction of the casting base, guiding the molten metal outwards. The molten metal solidifies into an ingot during the traction process. The sized matching of the casting head and the discharge end of the casting cavity, along with the detachable sealing structure, ensures both the sealing of the molten metal transport and facilitates disassembly and maintenance.
[0013] Furthermore, the ingot is rod-shaped, and a set of support rollers is provided below the ingot along its extension direction. The support roller set includes at least two sets of spaced-apart support rollers, the axis of each support roller being perpendicular to the axis of the rod-shaped ingot. The support rollers rotate synchronously with the movement of the rod-shaped ingot. The function of the support roller set is to stably support the ingot, preventing it from sagging and deforming due to its own weight. The synchronous rotation of the support rollers with the movement of the ingot reduces frictional damage between the ingot and the support rollers, ensuring smooth transport of the ingot along its extension direction, guaranteeing the appearance quality and straightness of the ingot, and simultaneously helping to maintain the stability of the ingot traction forming, thus improving the overall casting efficiency.
[0014] Furthermore, the idler roller includes a horizontal roller body made of copper alloy and an idler roller support seat for supporting the horizontal roller body, with both ends of the horizontal roller body rotatably connected to the idler roller support seat. The horizontal roller body is made of copper alloy, which has both good thermal conductivity and wear resistance, enabling it to quickly dissipate the heat transferred from the ingot, preventing overheating and deformation of the roller body, and also to withstand long-term friction, thus extending its service life.
[0015] Furthermore, the continuous casting mechanism is mounted on a fixed base. The fixed base is used to stabilize the overall structure of the device.
[0016] Furthermore, a fixed feeding mechanism is provided above the feeding chamber of the continuous casting device, and a cutting mechanism is provided at the discharge end of the continuous casting device. The fixed feeding mechanism above the feeding chamber of the continuous casting device can stably deliver amorphous alloy raw materials to the feeding chamber, avoiding the instability of manual feeding and the disruption of the vacuum environment, ensuring continuous and smooth feeding, and providing a stable supply of raw materials for subsequent smelting; the cutting mechanism at the discharge end of the continuous casting device can directly cut the formed ingot as needed, eliminating the need for a separate subsequent cutting process, shortening the production process, while ensuring cutting accuracy, reducing ingot loss, and improving overall production efficiency and the convenience of finished product processing.
[0017] The amorphous continuous casting device provided in this invention features a vacuum dual-chamber system and a vacuum extraction system to prevent raw material oxidation and ensure purity; an efficient melting mechanism for directional material pouring; a silicon carbide filter for precise impurity removal; a moving trough for precise station switching; and a sealed connection to prevent contamination. A casting head and a uniform-speed casting base ensure ingot forming; copper alloy rollers for stable ingot transport; and a fixed feeding mechanism and a discharge cutting mechanism optimize the process. The entire process is automated, reducing human error, avoiding casting defects, ensuring product quality and precision, and improving production efficiency. Attached Figure Description

[0022] The structure of the amorphous alloy continuous casting apparatus provided in this embodiment of the invention is shown in the attached figure. Figures 1-3 As stated above.
[0023] Specifically, the amorphous alloy continuous casting device provided in this embodiment includes a sealed and connected vacuum melting chamber 101 and a vacuum casting chamber 102, as well as a continuous casting mechanism. A melting and casting isolation door 107 is provided between the vacuum melting chamber 101 and the vacuum casting chamber 102. The melting and casting isolation door 107 can be opened and closed according to the needs of the actual manufacturing process, and can isolate the melting and casting sections at any time. The vacuum melting chamber 101 is externally connected to a vacuum pumping system 105 through a vacuum tube 106 to maintain the vacuum environment inside the chamber. The vacuum pumping system performs vacuum extraction on the entire device.
[0024] The top of the vacuum melting chamber 101 is detachably and sealed with a furnace cover 117 for external feeding. The lower part of the furnace cover 117 is integrated with a feeding chamber 103 for temporarily storing amorphous alloy raw materials. The bottom of the feeding chamber 103 is provided with a feeding port 104 for feeding materials into the chamber. A melting mechanism for melting amorphous alloy raw materials is provided directly below the feeding port 104. A filtering mechanism for filtering molten raw materials is installed directly below the melting mechanism.
[0025] In this embodiment, the melting mechanism includes an oxide melting crucible 108 for supporting amorphous alloy raw materials, and an induction heating coil surrounding the melting crucible 108 for induction heating and melting the raw materials inside the crucible. The induction heating coil is connected to a robotic arm, which can drive the induction heating coil to synchronously rotate the melting crucible, so that the molten amorphous alloy liquid inside the crucible is poured directionally into the filtration mechanism below through the opening of the melting crucible. In this embodiment, the filtration mechanism is a silicon carbide filter screen 109 with a mesh size of 200 μm, and the feed end of the silicon carbide filter screen 109 is correspondingly positioned below the opening of the melting crucible.
[0026] In some other embodiments, the mesh size of the filter screen can be selected in the range of 70 to 300 μm, depending on the quality of the smelting raw material.
[0027] In some other embodiments, a fixed feeding mechanism is provided above the feeding chamber to achieve automated feeding of equal quality and quantity.
[0028] In this embodiment, a movable groove 110 is provided in the vacuum casting chamber 102 along the horizontal direction. The movable groove 110 is connected to the power mechanism transmission 112. The power mechanism used in this embodiment is a hydraulic cylinder mechanism. Under the drive of the hydraulic cylinder mechanism 112, the movable groove 110 can reciprocate linearly along the communication direction between the vacuum melting chamber 101 and the vacuum casting chamber 102. The groove cavity of the movable groove 110 is used to receive the molten amorphous alloy raw material conveyed by the filtration mechanism.
[0029] The continuous casting mechanism includes a casting cavity 119 located below the moving trough 110, a casting head 116 movably connected to the discharge end of the casting cavity, and a casting base 114 fixedly disposed at the end of the casting head away from the casting cavity. The continuous casting mechanism is mounted on a fixed base 118. A molten flow channel 120 for guiding the flow of molten metal is provided through the bottom of the moving trough 110. The inlet end of the molten flow channel 120 is located at the bottom of the cavity of the moving trough 110, and the outlet end extends downward. Driven by the hydraulic cylinder mechanism 112, the moving tank 110 can move to the initial position directly below the filter screen 109 to receive the molten amorphous alloy filtered by the filter mechanism. After all the molten metal is injected into the moving tank 110, the hydraulic cylinder mechanism 112 drives the moving tank 110 to move horizontally to the casting position directly above the casting cavity 119. At this time, the outlet end of the molten metal flow channel 120 is sealed and connected to the inlet of the casting cavity 119, so that the molten amorphous alloy in the moving tank 110 can flow into the casting cavity 119 in a directional manner along the molten metal flow channel 120 to complete the casting.
[0030] The bottom of the moving trough 110 is also equipped with a set of moving wheels 111 for auxiliary movement. The moving wheel set includes at least two sets of rollers symmetrically distributed along the movement direction of the moving trough, and each roller is rotatably connected to the bottom of the moving trough through an axle. The bottom of the vacuum melting chamber 101 and the vacuum casting chamber 102 are provided with guide rails 121 that are adapted to the movement trajectory of the moving wheel set, and the moving wheel set can roll along the guide rails.
[0031] The casting head 116 is adapted to the size of the discharge end of the casting cavity, and the two are connected by a separable sealing structure. The casting base 114 is connected to its drive system and moves at a constant speed along the axis of the casting head during casting traction. This causes the casting head to move along the axis of the discharge end of the casting cavity under the traction of the casting base, directionally drawing out the molten liquid. The molten liquid solidifies into an ingot 115 during the traction process. The ingot 115 is rod-shaped, and a roller group 113 is provided below the ingot 115 along its extension direction. The roller group includes at least two sets of spaced rollers, and the axis of each roller is perpendicular to the axis of the rod-shaped ingot. The rollers rotate synchronously with the movement of the rod-shaped ingot. The rollers include a horizontal roller body 1131 made of copper alloy and a roller support seat 1132 for supporting the horizontal roller body. The two ends of the horizontal roller body are rotatably connected to the roller support seat.
[0032] In some other embodiments, the discharge end of the continuous casting mechanism is equipped with a cutting mechanism to facilitate the continuous melting-casting-cutting process on the production site, and to directly send the cut ingot particles to the amorphous forming process section to improve processing efficiency.
[0033] The amorphous alloy continuous casting apparatus provided in this embodiment realizes fully automated, high-purity production from raw materials to finished ingots.

Vacuum preparation: Close the melting and casting partition door 107, start the vacuum system 105, and evacuate the vacuum melting chamber 101 and the vacuum casting chamber 102 to the set vacuum level respectively.
[0034] 2. Feeding: Amorphous alloy raw materials are added through the feeding chamber 103. In the preferred embodiment, a fixed feeding mechanism can achieve automated, continuous feeding of equal quality.
[0035] 3. Smelting: The raw material falls into the oxide melting crucible 108 through the feed inlet 104.
[0036] The induction heating coil surrounding the crucible is energized to efficiently and uniformly heat the raw material until it melts.
[0037] After heating is complete, the robotic arm drives the induction heating coil, causing the melting crucible 108 to be precisely rotated, and the molten liquid is poured into the silicon carbide filter screen 109 below through the opening.
[0038] 4. Filtration: The molten metal passes through a 200μm silicon carbide filter 109 (adjustable within the range of 70-300μm) to effectively remove oxide inclusions and unmelted particles.
[0039] At this time, the moving tank 110 is located at the initial position (directly below the filter screen), receiving the filtered high-purity melt.
[0040] 5. Casting: After all the molten metal is injected into the moving tank 110, the hydraulic cylinder mechanism 112 drives the moving tank 110 to move along the guide rail 121 to the casting station (directly above the casting cavity).
[0041] The outlet end of the molten flow channel 120 at the bottom of the moving tank is sealed and connected to the inlet of the casting cavity 119, and the molten liquid flows into the casting cavity in a directional manner along the flow channel.
[0042] 6. Continuous casting: Driven by the drive system, the casting stand 114 moves at a constant speed along the axis of the casting head 116.
[0043] The casting head 116 draws the molten liquid out of the casting cavity 119 under traction, and the molten liquid cools and solidifies into a rod-shaped ingot 115 during the traction process.
[0044] 7. Conveying and cutting: The rod-shaped ingot 115 is supported by the copper alloy idler roller group 113 below and rotates synchronously with it to achieve stable conveying.
[0045] In the preferred embodiment, the cutting mechanism located at the discharge end can cut the ingot online to the required length and send it directly to the next process.
[0046] The amorphous alloy continuous casting apparatus in this embodiment achieves significant technical effects through the synergistic effect of its various systems: High purity of raw materials: The entire process is carried out in a vacuum environment with high-efficiency filtration, which reduces oxidation, gas absorption and inclusion contamination, ensuring the high purity and excellent mechanical properties of amorphous alloy products.
[0047] Excellent molding quality: From uniform induction heating and precise directional pouring to uniform traction and stable support, every step is precisely controlled, effectively avoiding casting defects such as cracks, porosity, and segregation, and ensuring accurate ingot dimensions and uniform structure.
[0048] High degree of automation and continuity: From fixed feeding, automatic tilting, and station switching to online cutting, the entire process is highly automated, reducing manual intervention and operational errors, and achieving stable and continuous production.
[0049] High efficiency and low cost: The compact process and smooth connections reduce intermediate transfer and waiting time. At the same time, precise control and efficient filtration improve raw material utilization and reduce equipment maintenance costs and scrap rates.
[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
