Description

Technical Field

[0001] The invention relates to the technical field of magnetic material processing, and in particular to a smelting device based on amorphous nanocrystalline magnetic materials. Background Art

[0002] Amorphous nanocrystalline soft magnetic alloy refers to a soft magnetic alloy with a nanocrystalline structure obtained by heat treatment on the basis of an amorphous alloy. It has excellent soft magnetic properties such as high saturation magnetic induction intensity, high resistivity, and low loss. The manufacturing process and use process of amorphous alloys are energy-saving, so amorphous nanocrystalline soft magnetic alloys are green energy-saving products that are the focus of contemporary development and are widely used in many fields such as military industry, medical treatment, and aviation.

[0003] Among them, heat treatment is the process of preparing magnetic materials with a composite structure of amorphous matrix and nano-grains through a specific high-temperature melting process combined with rapid solidification technology. Through composition design and melting control, the coordinated distribution of the material's disordered structure (amorphous) at the atomic scale and ordered grains (nanocrystals) at the nanoscale is achieved. In this special structure, the ferromagnetic exchange coupling between nanocrystals can greatly reduce the effective magnetocrystalline anisotropy of the alloy, thereby reducing the alloy's coercive force and increasing the effective magnetic permeability. Therefore, the average grain size of the nanocrystals precipitated from the alloy directly affects the soft magnetic properties. The smaller the grain size, the better the soft magnetic properties.

[0004] In a vacuum melting environment, the materials in the furnace are prone to insufficient mixing, and if the melt produced by the furnace is directly poured into a container statically, turbulence and splashing are easily formed, and gas is easily mixed into the melt to form pores or inclusions, resulting in uneven grain size distribution, reduced soft magnetic properties, and affecting the production quality of amorphous nanocrystalline magnetic materials. In order to address the shortcomings of the prior art, we propose a melting device based on amorphous nanocrystalline magnetic materials. Summary of the invention

[0032] like Figure 1As shown, a groove is provided on the left side of the limiting block 83. If the mechanism 8 is not tilted, the top of the control rod 82 can be stuck in the groove to limit the rotation of the control cylinder 81. Anyway, when the material is melted into a melt, the control rod 82 is held and rotated manually or by a mechanical arm to 100°, so that the control cylinder 81 drives the crucible 3 to rotate to an inclined state through the induction coil 2 and the support plate 23, so as to pour the melt into the collecting crucible 4. It should be noted that when the crucible 3 is rotated to the maximum angle, the top of the induction coil 2 does not contact the top surface of the smelting box 1;

[0033] like Figure 1 and Figure 3 As shown, the support tube 91 is fixedly connected to the right inner surface of the smelting box 1, and the support tube 91 is used to support the rotating rod 92. At the same time, the support tube 91 is connected to the connecting plate 22 on the right side of the induction coil 2 through the support plate 23, wherein the connection relationship between the support plate 23 and the support tube 91 is a rotation connection, and the support tube 91 also supports the induction coil 2 through the support plate 23. One end of the rotating rod 92 is rotatably connected to the right side wall of the control tube 81, and the other end of the rotating rod 92 penetrates the support tube 91 and the right side wall of the smelting box 1 and extends to the outside of the smelting box 1.

[0034] like Figure 3-Figure 4 As shown, a No. 1 groove 55 is provided at the top axis of the rotating cover 51, and the diameter of the No. 1 groove 55 is larger than the diameter of the top opening of the crucible 3, so that the material can be added into the crucible 3 through the No. 1 groove 55 when adding materials; the rotating cover 51 is circular and has a threaded groove 52 around the side, and the surface of the driving wheel 94 is also provided with a threaded groove 52. The driving wheel 94 is embedded with the rotating cover 51, so the driving wheel 94 can drive the rotating cover 51 to rotate. When the crucible 3 is not tilted, the driving wheel 94 drives the rotating cover 51 to rotate, so that the melt in the crucible 3 rotates, which is convenient for uniform mixing of the melts. When the crucible 3 is tilted, the driving wheel 94 drives the rotating cover 51 to rotate, and the crucible 3 rotates to make the melt rotate and pour into the collecting crucible 4 through the guide plate 57. The centrifugal force generated by the rotation promotes uniform distribution of the melt and mixing of components, improves the mixing effect of the melt, and has a slow flow rate and reduces gas mixing, thereby reducing splashing during pouring and the porosity of the solidified melt.

[0035] like Figure 4 and Figure 6 As shown, circular grooves are provided on the outer and inner surfaces of the top of the rotating cover 51, wherein the top of the connecting plate 22 is slidably connected in the circular groove of the inner surface, and the connecting plate 22 supports the rotating cover 51 to rotate;

[0036] like Figure 4-Figure 5 As shown, the H-shaped bracket 56 has two ends at the front and rear, the two ends at the front are slidably connected inside the circular groove on the outer surface of the top of the rotating cover 51, and the two ends at the rear are fixedly connected with rings, one of which is rotatably connected to the surface of the control cylinder 81, and the other is rotatably connected to the surface of the support cylinder 91. By pulling up the H-shaped bracket 56 and rotating it around the ring, the rotating cover 51 can be separated from the connecting plate 22.

[0037] like Figure 3-Figure 6 As shown, the cross bar of the H-shaped support rod is fixedly connected to the bottom surface of the guide plate 57, and a notch is opened inside the first groove 55, and the guide plate 57 can be slidably connected along the notch, so as to fix the position of the guide plate 57 without affecting the rotation of the rotating cover 51;

[0038] like Figure 4 and Figure 6 As shown, a plurality of blocks 53 are fixedly connected to the inner surface of the top of the rotating cover 51, and the plurality of blocks 53 are evenly distributed. A plurality of slots 54 are correspondingly provided on the top surface of the crucible 3. When the rotating cover 51 is covered on the induction coil 2, the blocks 53 are inserted into the slots 54, so that the rotating cover 51 can drive the crucible 3 to rotate synchronously.

[0039] The crucible 3 is not in contact with the inner side of the induction coil 2 on all sides, and can be rotatably connected with a ball on the inner surface of the arc plate 21. The ball can be made of tungsten material to improve the smoothness of the rotation of the crucible 3. At the same time, the rotating cover 51, the H-shaped bracket 56 and the guide plate 57 can be made of boron nitride material or coated with high-temperature resistant coating, such as ZS-1091 coating material.

[0040] like Figure 3 and Figure 8 As shown, a fixing plate 71 is provided between the connecting plates 22 on the rear side of the rotating cover 51, and a plurality of No. 1 rods 72 are fixedly connected to the upper surface of the fixing plate 71, and a positioning plate 73 is rotatably connected to the top of the No. 1 rod 72. When the positioning plate 73 rotates to the top of the rotating cover 51, the positioning plate 73 will block the rotating cover 51 from rotating around the center of the circle. Conversely, the positioning plate 73 will be pushed away from the top of the rotating cover 51, and the fixing of the positioning plate 73 to the rotating cover 51 will be released, thereby realizing the fixing and loosening effect of the loading and unloading mechanism 7 on the rotating cover 51.

[0041] like Figure 3 and Figure 5As shown, a No. 2 rod 6 is fixedly connected to the rear end of the H-shaped bracket 56. The No. 2 rod 6 is symmetrically arranged. The tail of the No. 2 rod 6 is located above the opening of the crucible 3 and is provided with a slide groove. The stirring rod 61 can be slidably connected in the slide groove. When the rotating cover 51 is covered on the induction coil 2, under the action of its own gravity, the stirring rod 61 slides in the slide groove and the bottom of the stirring rod 61 contacts the bottom surface of the crucible 3. When the rotating cover 51 rotates, the stirring rod 61 is stationary, so that the melt in the crucible 3 is passively stirred by the stirring rod 61 to improve the uniformity of melt mixing. The stirring rod 61 can also be provided with a plate to scrape off the melt adhered to the inner wall of the crucible 3. The stirring rod 61 can also be provided with straight rods of different levels to improve the stirring effect of the stirring rod 61.

[0042] It should be noted that the present invention is a smelting device based on amorphous nanocrystalline magnetic materials, such as Figure 1-Figure 8 As shown, when in use, the material to be smelted is added into the crucible 3, wherein part of the material is added into the crucible 3 through the feeding port, then the rotating cover 51 is covered on the top of the connecting plate 22, and the rotating positioning plate 73 is moved to the top of the rotating cover 51, and then the box doors 11 before and after the smelting box 1 are closed, the air is pumped to make the inside of the smelting box 1 in a vacuum and the induction coil 2 is started, and when all the materials are melted into a melt, the motor 93 drives the driving wheel 94 to rotate through the rotating rod 92, and the driving wheel 94 drives the crucible 3 to rotate forward and reversely inside the induction coil 2 through the rotating cover 51. After rotating for a period of time, the motor 93 stops and the control rod 82 is rotated to rotate the crucible 3 from horizontal to inclined 100°, and then the motor 93 is started to rotate the melt through the guide plate 57 and pour it into the collecting crucible 4, and after adjusting the pressure difference between the inside and outside of the smelting box 1, the box door 11 is opened to take out the collecting crucible 4.
