DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0040] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0041] Example 1

[0042] like Figure 1-Figure 5 、 Figure 8 and Figure 9 As shown, a smelting furnace includes a furnace body 100 , a stirring mechanism 200 , a reflux mechanism 400 , a dual-axis motor 500 and a base 300 .

[0043] A material pipe 110 is mounted on the side of the furnace body 100. A smelting chamber 101 and an installation chamber 102 are provided within the furnace body 100. The smelting chamber 101 is used to smelt the nanocrystalline soft magnetic alloy; a heater 103 is installed within the installation chamber 102. A stirring mechanism 200 is rotatably mounted on the top surface of the furnace body 100 and is used to stir the liquid nanocrystalline soft magnetic alloy within the smelting chamber 101. A reflux mechanism 400 is located above the furnace body 100 and communicates with the smelting chamber 101. This reflux mechanism 400 is used to cool the alloying additives volatilized during smelting into a liquid and then reflux them back into the smelting chamber 101. A dual-axis motor 500 is mounted on the reflux mechanism 400 and is used to drive the stirring mechanism 200 to rotate. The dual-axis motor 500 has an upper power output shaft and a lower power output shaft.

[0044] Two rotating shafts 301 and a first hydraulic cylinder 302 are provided in the base 300. One end of the two rotating shafts 301 is rotatably connected to the inner wall of the base 300, and the other end of the two rotating shafts 301 is fixedly connected to the furnace body 100. One end of the first hydraulic cylinder 302 is hinged to the base 300, and the extended end of the first hydraulic cylinder 302 is hinged to the furnace body 100.

[0045] Specifically, the furnace body 100 is heated by the heater 103, and then the nanocrystalline soft magnetic alloy raw material in the smelting chamber 101 is heated and liquefied. Then, the dual-axis motor 500 is started to drive the stirring mechanism 200 to rotate, so that the stirring mechanism 200 stirs the liquid nanocrystalline soft magnetic alloy in the smelting chamber 101; during smelting, some alloy additives (such as metal boron) will evaporate and enter the reflux mechanism 400, and the reflux mechanism 400 will cool the volatilized alloy additives into liquid and reflux the liquid into the smelting chamber 101.

[0046] like Figure 4-Figure 6 As shown, the reflux mechanism 400 includes a cylinder 401 , a plurality of vent pipes 404 , a plurality of exhaust pipes 405 , a condenser 406 and a boss 407 .

[0047] The cylinder 401 includes a gas cavity 402 and a cooling liquid cavity 403 . The cooling liquid cavity 403 is used to contain cooling liquid.

[0048] One end of each of the multiple vent pipes 404 is connected to the smelting chamber 101 of the furnace body 100, and the other end of each of the multiple vent pipes 404 is connected to the gas chamber 402. There are four vent pipes 404, which are equidistantly installed on the bottom surface of the cylinder 401. One end of each of the multiple exhaust pipes 405 is connected to the gas chamber 402, and the other end of each of the multiple exhaust pipes 405 extends outside the cylinder 401.

[0049] Condenser 406 is mounted on the top surface of cylinder 401. Condenser 406 is used to cool the coolant in coolant chamber 403. Condenser 406 is a mature technology, and its working principle will not be described in detail. Boss 407 is mounted on the inner bottom surface of cylinder 401. Boss 407 is high in the middle and low on the sides, so that liquid on boss 407 flows downward along boss 407.

[0050] Specifically, when the nanocrystalline soft magnetic alloy is being smelted, some alloy additive elements (such as boron) will volatilize and enter the cylinder 401. Since the temperature of the cylinder 401 is relatively low, when the volatilized alloy additive elements come into contact with the cylinder 401, they will cool into liquid, and then under the influence of gravity, the liquid will flow downward and then flow back into the smelting chamber 101 through the vent pipe 404, thereby avoiding changes in the proportion of the alloy formed by smelting.

[0051] like Figure 4-Figure 6 As shown, the reflux mechanism 400 further includes a striking assembly 410 , a first shaft 420 and a second bevel gear 421 .

[0052] The striking assembly 410 includes a crossbar 411, multiple rubber rods 412, multiple rubber balls 413, and a first bevel gear 414. Both ends of the crossbar 411 are rotatably connected to the inner wall of the cylinder 401. The multiple rubber rods 412 are fixedly connected to the crossbar 411. The multiple rubber balls 413 are respectively fixedly connected to the ends of the multiple rubber rods 412 away from the crossbar 411. The first bevel gear 414 is fixedly mounted on the crossbar 411. It should be noted that the rubber material here must be high-temperature resistant.

[0053] The first shaft 420 extends through the boss 407 and the bottom surface of the cylinder 401 and is rotatably connected to both. The lower end of the first shaft 420 is fixedly connected to the upper power output shaft of the dual-axis motor 500, which is mounted on the bottom surface of the cylinder 401. The second bevel gear 421 is fixedly connected to the upper end of the first shaft 420 and meshes with the first bevel gear 414.

[0054] Specifically, when the dual-axis motor 500 is running, the upper power output shaft of the dual-axis motor 500 will drive the first shaft 420 to rotate, and then drive the second bevel gear 421 to rotate, and then engage and drive the second bevel gear 421 to rotate, and then drive the cross bar 411 and multiple rubber rods 412 to rotate, and then drive the rubber ball 413 to rotate and hit the inner top surface of the cylinder 401, causing the inner top surface of the cylinder 401 to produce periodic vibration. The generated periodic vibration can accelerate the downward flow of liquid on the inner wall of the cylinder 401.

[0055] like Figures 1-4 and Figure 6-Figure 9As shown, a blocking mechanism 130 is installed on the material pipe 110, and the blocking mechanism 130 is used to block the material pipe 110. The blocking mechanism 130 includes a fixing frame 131, a connecting plate 133, a blocking plate 134 and a second hydraulic cylinder 135.

[0056] Fixing bracket 131 is mounted on material pipe 110. Fixing bracket 131 is inverted L-shaped, with a through slot 132 extending through the vertical portion of fixing bracket 131. Connecting plate 133 is inverted L-shaped, extending through through slot 132 and rotatably connected thereto. A sealing plate 134 is fixedly connected to the vertical portion of connecting plate 133 and is used to seal material pipe 110.

[0057] One end of the second hydraulic cylinder 135 is hinged to the fixing frame 131 , and an extended end of the second hydraulic cylinder 135 is hinged to the connecting plate 133 .

[0058] Specifically, when the extension end of the second hydraulic cylinder 135 extends, the connecting plate 133 rotates counterclockwise, thereby causing the sealing plate 134 to move upward and separate from the material pipe 110, thereby facilitating the addition of nanocrystalline soft magnetic alloy raw materials into the furnace body 100 or pouring out the liquid nanocrystalline soft magnetic alloy after smelting.

[0059] like Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, a mounting groove is provided on the base 300, in which an air pump 310 is installed. A metal telescopic tube 311 is installed at the air outlet end of the air pump 310, and the other end of the telescopic tube 311 is connected to the smelting chamber 101, and the telescopic tube 311 can be deformed.

[0060] Specifically, before smelting the nanocrystalline soft magnetic alloy, the exhaust end of the air pump 310 is connected to an inert gas (such as argon) storage container, and then the inert gas is transported into the furnace body 100 through the air pump 310. This can reduce the oxidation and volatilization of the metal surface when smelting the nanocrystalline soft magnetic alloy.

[0061] When using a melting furnace to melt nanocrystalline soft magnetic alloy: first start the second hydraulic cylinder 135, so that the extended end of the second hydraulic cylinder 135 extends, causing the connecting plate 133 to rotate counterclockwise, and then the sealing plate 134 moves upward and separates from the material pipe 110, thereby facilitating the addition of nanocrystalline soft magnetic alloy raw materials into the furnace body 100. After completion, start the second hydraulic cylinder 135, retract the extended end of the second hydraulic cylinder 135, and allow the sealing plate 134 to seal the material pipe 110.

[0062] Then, the inert gas is transported into the furnace body 100 through the air pump 310 by connecting the air pump end of the air pump 310 to the inert gas storage container.

[0063] Then, by starting the heater 103, the heater 103 heats the furnace body 100, thereby heating the nanocrystalline soft magnetic alloy raw material in the smelting chamber 101 and liquefying the nanocrystalline soft magnetic alloy raw material. Then, the dual-axis motor 500 is started to drive the stirring mechanism 200 to rotate, so that the stirring mechanism 200 stirs the liquid nanocrystalline soft magnetic alloy in the smelting chamber 101, thereby accelerating the mixing efficiency of the liquid nanocrystalline soft magnetic alloy.

[0064] During smelting, the condenser 406 is started to cool the coolant in the cylinder 401, thereby reducing the temperature of the cylinder 401. During the smelting process, some alloy additives will volatilize and enter the cylinder 401. Since the temperature of the cylinder 401 is relatively low, when the volatilized alloy additives come into contact with the cylinder 401, they will be cooled into liquid. When the dual-axis motor 500 is running, the upper power output shaft of the dual-axis motor 500 will drive the first shaft 420 to rotate, thereby driving the second bevel gear 421 to rotate, and then meshing and driving the second bevel gear 421 to rotate, thereby driving the cross bar 411 and multiple rubber rods 412 to rotate, and then driving the rubber ball 413 to rotate and hit the top surface of the cylinder 401, causing the top surface of the cylinder 401 to vibrate, thereby accelerating the downward flow of liquid metal on the inner wall of the cylinder 401, so that the liquid flows back into the smelting chamber 101 through the vent pipe 404, thereby avoiding changes in the alloy ratio formed by smelting.

[0065] After the liquid nanocrystalline soft magnetic alloy is evenly stirred, the second hydraulic cylinder 135 is first started to extend the extension end of the second hydraulic cylinder 135, so that the connecting plate 133 rotates counterclockwise, and then the blocking plate 134 moves upward and separates from the material pipe 110; then the first hydraulic cylinder 302 is started to contract the extension end of the first hydraulic cylinder 302, thereby pulling the furnace body 100 to rotate, so that the furnace body 100 tilts to one side, and then the liquid nanocrystalline soft magnetic alloy in the smelting chamber 101 is poured out through the material pipe 110, thereby facilitating the next step of processing of the liquid nanocrystalline soft magnetic alloy.

[0066] In summary, the smelting furnace in this embodiment has the following beneficial effects:

[0067] 1. The smelting furnace of the present invention is provided with a furnace body 100, a smelting chamber 101 and a reflux mechanism 400. When smelting the nanocrystalline soft magnetic alloy, some alloy additives will volatilize and enter the reflux mechanism 400. The reflux mechanism 400 will cool the volatilized alloy additives into liquid. Under the influence of gravity, the liquid will flow downward and then flow back into the smelting chamber 101, thereby avoiding changes in the proportion of the alloy formed by smelting.

[0068] 2. The stirring mechanism 200 of the present invention is provided with a second shaft 201, a rotating plate 202, a vertical rod 203, stirring blades 204 and a gear 205. When the dual-axis motor 500 is running, the multiple stirring blades 204 not only rotate with the second shaft 201 as the center of the circle, but also rotate with the vertical rod 203 as the center of the circle, so that the stirring area of ​​the multiple stirring blades 204 is larger, thereby accelerating the mixing efficiency of the liquid nanocrystalline soft magnetic alloy.

[0069] Example 2

[0070] like Figure 4 and Figure 5 As shown, while other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that a gear ring 120 is installed in the central area of ​​the inner top surface of the furnace body 100, and the stirring mechanism 200 includes a second shaft 201, a rotating plate 202, a vertical rod 203, a plurality of stirring blades 204 and a gear 205.

[0071] A second shaft 201 extends through the top surface of the furnace body 100 and is rotatably connected thereto. The upper end of the second shaft 201 is fixedly connected to the lower power output shaft of the dual-shaft motor 500. A rotating plate 202 is fixedly connected to the lower end of the second shaft 201. A vertical rod 203 extends through the rotating plate 202 and is rotatably connected thereto. Three stirring blades 204 are equidistantly mounted on the sides of the vertical rod 203. A gear 205 is fixedly mounted on the upper end of the vertical rod 203 and meshes with the gear ring 120.

[0072] When using a smelting furnace to smelt nanocrystalline soft magnetic alloys: by starting the heater 103, the heater 103 heats the furnace body 100, and then heats the nanocrystalline soft magnetic alloy raw material in the smelting chamber 101 and liquefies the nanocrystalline soft magnetic alloy raw material, then, start the dual-axis motor 500 to drive the second shaft 201 to rotate, when the second shaft 201 rotates, it will drive the rotating plate 202 to rotate, and then drive the vertical rod 203 to rotate with the second shaft 201 as the center of the circle, at the same time, the vertical rod 203 will rotate under the joint action of the gear 205 and the gear ring 120, and then drive the multiple stirring blades 204 to rotate with the vertical rod 203 as the center of the circle, to stir the liquid nanocrystalline soft magnetic alloy in the smelting chamber 101.

[0073] When the dual-axis motor 500 is running, the multiple stirring blades 204 not only rotate around the second shaft 201 as the center of the circle, but also rotate around the vertical rod 203 as the center of the circle, so that the stirring area of ​​the multiple stirring blades 204 is larger, thereby accelerating the mixing efficiency of the liquid nanocrystalline soft magnetic alloy.

[0074] In summary, the smelting furnace in this embodiment has the following beneficial effects: by setting up the air pump 310 and the telescopic tube 311, before the nanocrystalline soft magnetic alloy is smelted, the exhaust end of the air pump 310 is connected to the inert gas storage container, and the inert gas is transported into the furnace body 100 through the air pump 310. When the nanocrystalline soft magnetic alloy is smelted, the inert gas can reduce the oxidation and volatilization of the metal surface.

[0075] Example 3

[0076] like Figures 1-10 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that the smelting furnace also includes a temperature monitoring and processing control system. The temperature monitoring and processing control system can judge the mixing state of the liquid nanocrystalline soft magnetic alloy according to the temperature of the liquid nanocrystalline soft magnetic alloy in each area in the smelting chamber 101, and control the start of the first hydraulic cylinder 302 or increase the operating time of the dual-axis motor 500 according to the mixing state of the liquid nanocrystalline soft magnetic alloy.

[0077] The temperature monitoring and processing control system includes a temperature monitoring module, a data processing module and a control module.

[0078] The temperature monitoring module is used to monitor the temperature of the liquid nanocrystalline soft magnetic alloy in multiple areas within the smelting chamber 101 .

[0079] A data processing module is used to analyze the temperature data of each area transmitted by the temperature monitoring module and determine whether the mixing state of the liquid nanocrystalline soft magnetic alloy is sufficient or insufficient;

[0080] The control module is configured to generate an instruction to increase the operating time of the dual-axis motor 500 or to start the first hydraulic cylinder 302 and the second hydraulic cylinder 135 according to the hybrid state.

[0081] The workflow of the temperature monitoring and control system is as follows:

[0082] Step 1: The temperature monitoring module monitors the temperature of the liquid nanocrystalline soft magnetic alloy in multiple areas within the smelting chamber 101 and transmits the collected temperature data T1 to the data processing module;

[0083] Step 2: The data processing module compares the multiple temperature data T1 with the preset value T2 and calculates the deviation value ΔT=T2-T1;

[0084] Step 3: The data processing module compares the maximum deviation value ΔT with the allowable error range. If ΔT is less than the allowable error range, it is determined that the liquid nanocrystalline soft magnetic alloy is sufficiently mixed; if ΔT is greater than the allowable error range, it is determined that the liquid nanocrystalline soft magnetic alloy is insufficiently mixed.

[0085] Step 4: If the data processing module determines that the liquid nanocrystalline soft magnetic alloy is not sufficiently mixed, the control module increases the operating time of the dual-axis motor 500, thereby increasing the stirring time of the stirring mechanism 200;

[0086] Step 5: Repeat steps 1 to 4 until the data processing module determines that the liquid nanocrystalline soft magnetic alloy is fully mixed;

[0087] Step 6: The control module controls the activation of the first hydraulic cylinder 302 and the second hydraulic cylinder 135, causing the extension end of the second hydraulic cylinder 135 to extend, separating the blocking plate 134 from the material pipe 110, and causing the extension end of the first hydraulic cylinder 302 to retract, causing the furnace body 100 to tilt to one side, thereby pouring the liquid nanocrystalline soft magnetic alloy in the smelting chamber 101 out through the material pipe 110;

[0088] In step 1, the internal space of the smelting chamber 101 is vertically and evenly divided into 6 sector-shaped areas. The temperature monitoring module monitors the temperature of the liquid nanocrystalline soft magnetic alloy in the above 6 sector-shaped areas respectively, and marks the collected temperature data as T1. In step 3, the value of the allowable error range can be set by yourself. In this embodiment, the allowable error range is 5 degrees Celsius.

[0089] If it is determined that the liquid nanocrystalline soft magnetic alloy is not sufficiently mixed, the following formula is used to calculate the increased running time of the dual-axis motor 500:

[0090]

[0091] Wherein, t is the operating time of the dual-axis motor 500 (in seconds), m is the mass of the liquid nanocrystalline soft magnetic alloy (in kilograms), c is the specific heat capacity of the liquid nanocrystalline soft magnetic alloy (in joules / (kilograms·degrees Celsius)), ΔT is the temperature deviation value (in degrees Celsius), P is the power of the dual-axis motor 500 (in watts), and k is the stirring efficiency coefficient of the stirring mechanism 200 (in seconds / kilogram).

[0092] Through calculation, the appropriate stirring time can be calculated based on the mass, specific heat capacity, temperature deviation value of the liquid nanocrystalline soft magnetic alloy, the power of the dual-axis motor 500 and the stirring efficiency coefficient of the stirring mechanism 200, so as to improve the quality and efficiency of smelting and reduce energy consumption and cost.

[0093] In summary, the smelting furnace in this embodiment has the following beneficial effects: the temperature monitoring and processing control system in the present invention collects and analyzes the temperature data of the liquid nanocrystalline soft magnetic alloy by setting a temperature monitoring module, a data processing module and a control module, and controls the driving mechanism to optimize the mixing and stirring strategy based on the analysis and judgment results, so as to improve the efficiency of the smelting process, and at the same time, reduce energy consumption and cost.

[0094] Example 4

[0095] While other parts are the same as those in Example 2, the difference between this embodiment and Example 2 is that:

[0096] An electromagnetic stirrer is installed at the bottom of the furnace body 100 to replace the stirring mechanism 200 and the dual-axis motor 500, and the stirring uniformity is improved by using the magnetic field change. If this is done, a single-axis drive motor needs to be installed at the bottom of the cylinder 401 to drive the first shaft 420 to rotate.
