[0018] A method for using an intelligent melting furnace for preparing beryllium copper alloys, the method of using the melting furnace is as follows:

[0019] S1. Add the raw materials for beryllium copper alloy preparation into the furnace body, cover the furnace lid, and then start the vacuum pump to maintain the vacuum state for alloy preparation in the furnace body. The induction coil is energized to generate an alternating magnetic field, which heats and melts the raw materials in the furnace body and promotes the flow of the raw materials.

[0020] S2. During the alloy production process, the temperature detection unit detects the alloy temperature. When temperature stratification occurs, a uniform module is used to guide the raw materials.

[0021] S3. During the alloy melting process, the temperature inside the furnace shell rises. The heat energy between the furnace shell and the furnace body is converted into electrical energy by the conversion unit, which is then transmitted and stored in the energy management unit. The energy management unit provides electrical energy to the heating plate, enabling the heating plate to provide auxiliary heating to the raw materials inside the furnace.

[0022] S4. When heat dissipation of the furnace body is required, drive the insulation plate three to rotate, so that the through groove two on the insulation plate three is aligned with the through groove one on the insulation plate two, so that the insulation unit is hollowed out. Then, coolant is output into the cooling pipe and the fan is started to blow air into the furnace shell to cool the furnace body.

[0023] Preferably, step S2 further includes the following steps:

[0024] S21. The use of the uniform module involves first rotating the hollow rod to drive the first and second arc plates to rotate until they are separated from the inner wall of the furnace. Then, the rotating motor drives the rotating frame to rotate, causing the rotating frame to push the second arc plate to rotate to an inclined state. The inclined arc plate guides the alloy raw material and adjusts the flow path of the alloy raw material.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention, through the installation of a uniform module, addresses the issue of temperature stratification during furnace charge heating. A hollow rod drives arc plates one and two to rotate until they separate from the furnace wall. A rotating motor then drives a rotating frame, which in turn rotates arc plate two to an inclined position. As arc plate two rotates, a micro-telescopic rod shortens, separating arc plate three from the inner wall of the conical ring. After arc plate two completes its rotation, arc plate three adheres to the inner wall of the conical ring, thus fixing arc plate two and achieving angle adjustment. This allows the molten charge to flow in a vortex state while arc plate two guides the charge, adjusting its flow path and ensuring uniform mixing. This results in consistent charge temperature, preventing uneven heating and improving the quality of beryllium copper alloys.

[0027] 2. This invention is equipped with a conversion module, including a conversion unit and an energy management unit. During the melting process of the alloy raw materials, the conversion unit converts the heat between the furnace body and the furnace shell into electrical energy, which is then transmitted to the energy management unit for rectification, storage and distribution. When the heating efficiency of the induction coil is low, the energy management unit supplies power to the heating plate, which assists the induction coil in heating and melting the furnace material, thereby realizing the recovery and utilization of heat energy and improving the efficiency of alloy preparation.

[0028] 3. This invention intercepts heat by installing a heat insulation unit to prevent heat diffusion, thereby enabling the hot end of the conversion unit to effectively receive and transfer more heat energy, thus improving the heat recovery effect. By setting a cooling pipe on the outside of the conversion unit and injecting coolant into the cooling pipe, the heat loss rate of the cold end is accelerated, thereby improving the energy conversion efficiency and accelerating the heat recovery.

[0029] 4. This invention is equipped with a heat preservation unit, including heat preservation plate one, heat preservation plate two, and heat preservation plate three. When rapid cooling of the furnace body is required, servo motor two drives the lead screw to rotate, which in turn causes the worm gear to drive heat preservation plate three to rotate, aligning through slot two and through slot one, making the heat preservation unit hollow. Then, by injecting coolant into the cooling pipe and blowing air out of the air outlet, the low-temperature airflow is blown to the surface of the furnace body, thereby accelerating the cooling efficiency of the furnace body.

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An embodiment of the present invention provides an intelligent smelting furnace for beryllium copper alloy preparation, comprising a furnace shell 1, a furnace cover 2, and a furnace body 3. The furnace body 3 is embedded inside the furnace shell 1. An induction coil 4 is disposed between the outer wall of the furnace body 3 and the inner wall of the furnace shell 1. The furnace cover 2 is installed on the top of the furnace body 3 to seal the opening at the top of the furnace body 3. A uniform module is disposed inside the furnace body 3. The uniform module includes a hollow rod 8, an arc plate 1 9, and an arc plate 2 11. The hollow rod 8 is installed through the top of the furnace cover 2. There are three sets of hollow rods 8, and the hollow rods 8 extend into the interior of the furnace body 3. An arc plate 1 9 is sleeved on the outer wall of the hollow rod 8. A connecting block 10 is embedded at one end of the arc plate 1 9. The right end of the connecting block 10 is connected to the arc plate 2 11. The outer walls of the arc plate 1 9 and the arc plate 2 11 are in contact with the inner wall of the furnace body 3. The hollow rod 8, the arc plate 1 9, and the arc plate 2 11 are uniformly distributed inside the furnace body 3.

[0044] A conical ring 12 is embedded in the left end of the connecting block 10. The inner surface of the conical ring 12 is frustoconical. An installation groove 13 is provided inside the arc plate 9. One end of the installation groove 13 extends to one side of the conical ring 12. A fixing ring 17 and a fixing frame 14 are fixedly installed inside the installation groove 13. The fixing frame 14 is located to the right of the fixing ring 17 and extends into the conical ring 12. A push rod 16 passes through the outer wall of the fixing ring 17. A sliding ring 15 is sleeved on the outer wall of the push rod 16. The sliding ring 15 is fixedly connected to the outer wall of the push rod 16. The outer wall of the sliding ring 15 is slidably connected to the inner wall of the installation groove 13. The sliding ring 15 is located to the left of the fixing ring 17. A spring 18 is installed between the sliding ring 15 and the fixing ring 17. The spring 18 is sleeved on the outer side of the push rod 16. A conical block 19 is installed at the right end of the push rod 16. The conical block 19 is frustoconical and is located inside the fixing frame 14. Two sets of push blocks 20 are installed through the wall, and a conical block 19 is located between the two sets of push blocks 20. The side of the push block 20 closest to the conical block 19 is inclined. Arc plates 21 are installed on the sides of the two sets of push blocks 20 that are far apart from each other. When the push block 20 is squeezed by the conical block 19, the outer wall of the arc plate 21 fits against the inner wall of the conical ring 12, and the outer wall of the arc plate 21 and the inner wall of the conical ring 12 are rough inclined surfaces. A spring 22 is installed inside the fixing frame 14. There are two sets of installation groups for spring 22, and spring 22 is used to connect the fixed frame 14 and the push block 20. A miniature telescopic rod 23 is installed on the top wall of the hollow rod 8. The output end of the miniature telescopic rod 23 is connected to the vertical rod 24. A support rod 25 is installed on the outer wall of the vertical rod 24. The support rod 25 passes through the outer wall of the hollow rod 8 and extends into the mounting groove 13. The end of the push rod 16 away from the connecting block 10 is inclined, and the end of the support rod 25 away from the vertical rod 24 is inclined.

[0045] A rotary motor 26 and a PID controller 6 are installed on the top of the furnace cover 2. The rotary motor 26 is located at the center of the furnace cover 2. A rotating frame 27 is installed at the output end of the rotary motor 26. Three sets of long rods are included at the same height position of the rotating frame 27. A temperature detection module is installed inside the furnace body 3. The temperature detection module is a temperature sensor array or thermocouple. The temperature detection unit 5 is located on one side of the uniform module. The temperature detection module is electrically connected to the PID controller 6. A servo motor 7 is fixedly installed on the top of the furnace cover 2 through a support frame. The output end of the servo motor 7 is connected to the top of a set of hollow rods 8. A gear 28 is sleeved on the outer wall of the hollow rods 8. A gear 29 is meshed on the outer wall of the gear 28. Both gear 28 and gear 29 are located on the top of the furnace cover 2.

[0046] Furthermore, during the alloy preparation process, raw materials are added to furnace body 3. An alternating magnetic field is generated by energizing induction coil 4, causing the raw materials to form a closed loop in the magnetic field. This induces an electromotive force and eddy currents in the raw materials, causing them to heat up and melt. Simultaneously, the raw materials are stirred. During the heating and melting process of the alloy raw materials, the temperature of the molten raw materials is detected by temperature detection unit 5. When there is a temperature stratification phenomenon in the raw materials within furnace body 3, i.e., the temperature of the upper and lower layers of raw materials is uneven, servo motor 7 is activated to drive a set of hollow rods 8 to rotate. Under the meshing transmission of gear 1 28 and gear 2 29, the three sets of hollow rods 8 rotate synchronously. Hollow rod 8 drives arc plate 1 9 and arc plate 2 11 to rotate, causing them to separate from the interior of furnace body 3. Rotation motor 26 is then activated, driving rotating frame 27 to rotate, causing the long rod in rotating frame 27 to contact the inner surface of arc plate 2. At this time, miniature telescopic rod 23 shortens, pulling vertical rod 24 and causing support rod 25 to move upwards, separating the inclined surface of support rod 25 from the inclined surface of push rod 16. Push rod 16 loses the pressure of support rod 25, and spring 1 18 pushes sliding ring 15, causing push rod 16 to move slightly closer to hollow rod 8. Push rod 16 then moves conical block 19, causing the conical block to... The contact area between block 19 and push block 20 decreases. Under the pull of spring 22, push block 20 causes arc plate 3 21 to move closer to each other, causing the outer surface of arc plate 3 21 to separate from the inner surface of conical ring 12. Rotating frame 27 continues to rotate, causing long rod to push arc plate 2 11 to rotate, causing connecting block 10 to rotate, so that arc plate 2 11 rotates to an inclined state. The rotation angle of rotating frame 27 is controlled by PID controller 6, thereby controlling the inclination angle of arc plate 2. When arc plate 2 is adjusted to the inclination angle, miniature telescopic rod 23 pushes vertical rod 24 downward, causing long rod to move downward and squeeze push rod 16, causing push rod 16 to move closer to each other. The connecting block 10 moves in one direction, and the push rod 16 drives the conical block 19 to move and press the push block 20, so that the push block 20 drives the arc-shaped three-way outward to fit against the rough inner wall of the conical ring 12, fixing the connecting block 10, and then fixing the arc plate 2 11, so as to achieve the purpose of adjusting the angle of the arc plate 2 11. While the molten charge flows in a vortex state, the charge is guided by the arc plate 2 11 to achieve the purpose of adjusting the flow path of the charge, so as to mix the charge evenly, thereby making the charge temperature uniform and avoiding the phenomenon of uneven heating of the charge, which is conducive to improving the quality of beryllium copper alloy.

[0047] Please see Figure 1 and Figure 6One embodiment of the present invention provides an intelligent melting furnace for preparing beryllium copper alloy, including a vacuum pump 30 installed on the top of the furnace cover 2. The vacuum pump 30 is located to the right of the rotating motor 26. The vacuum pump 30 is used to maintain the vacuum state inside the furnace body 3. Alternatively, the top of the furnace cover 2 may also include an inert gas adder, which is used to replenish inert gas into the furnace body 3, thereby placing the alloy charge in an inert gas atmosphere and preventing oxidation during the alloy melting process.

[0048] Please see Figure 6 and Figure 7 One embodiment of the present invention provides an intelligent melting furnace for preparing beryllium copper alloy, comprising a conversion module disposed inside the furnace shell 1. The conversion module includes a conversion unit located inside the furnace shell 1 and outside the induction coil 4. The conversion unit includes a hot end 33, a connecting end 32, and a cold end 31. The hot end 33 and the cold end 31 are conductor materials of different shapes, such as copper plates. The connecting end 32 is made of two different thermoelectric materials, such as P-type and N-type bismuth telluride. An annular cold end 31 is sleeved on the outer side of the furnace body 3, and the number of cold ends 31 is multiple. The components are evenly distributed inside the furnace shell 1. The outer wall of the cold end 31 is provided with a connecting end 32. The connecting end 32 includes P-type thermoelectric material and N-type thermoelectric material, and is located on both sides of the furnace body 3 respectively. The end of the connecting end 32 away from the furnace body 3 is connected to the hot end 33. The hot end 33 is an arc-shaped plate, and the two sets of hot ends 33 are located on both sides of the furnace body 3 respectively. The interior of the furnace shell 1 is provided with a heat preservation unit 36, and the connecting end 32 passes through the heat preservation unit 36. The interior of the furnace shell 1 is provided with a spiral cooling pipe 37, and the cooling pipe 37 is located outside the conversion unit.

[0049] The conversion module also includes an energy management unit 34 located on the back of the furnace shell 1. The energy management unit 34 is electrically connected to the hot end 33 via wires. The energy management unit 34 includes a rectifier, a converter, and a battery pack. An electric heating plate 35 is embedded inside the furnace body 3. The electric heating plate 35 is adapted to the battery pack. A liquid level sensor 41 is installed on the bottom wall of the furnace cover 2. The liquid level sensor 41, the electric heating plate 35, and the energy management unit 34 are electrically connected.

[0050] Furthermore, during the heating and melting process of the furnace charge, the temperature in the space between the inside of the furnace shell 1 and the outside of the furnace body 3 rises. The heat diffusion is reduced by the heat insulation unit 36, and the heat is received by the hot end 33 and dissipated from the cold end 31 after passing through the connection end 32. The heat energy is converted into electrical energy by the conversion unit and transmitted to the energy management unit 34 for rectification, stabilization, storage and distribution. During the heat dissipation process at the cold end 31, coolant is injected into the cooling pipe 37 to accelerate the heat dissipation rate at the cold end 31, thereby improving the energy conversion efficiency and accelerating the recovery of heat energy. The temperature of the furnace charge inside the furnace body 3 is detected by the temperature detection unit 5. When the efficiency of heating the furnace charge by the induction coil 4 is low, the liquid level sensor 41 detects the liquid level of the furnace charge inside the furnace body 3 and supplies power to the electric heating plate 35 through the energy management unit 34. The electric heating plate 35 located below the liquid level of the furnace charge is energized to heat the furnace charge inside the furnace body 3, thereby achieving the purpose of auxiliary induction coil 4 to heat the furnace charge and improving the heating and melting efficiency of the furnace charge.

[0051] Please see Figure 1 , Figure 7 , Figure 8 and Figure 9 An embodiment of the present invention provides an intelligent smelting furnace for beryllium copper alloy preparation, comprising multiple sets of connecting pipes 39 arranged along the height direction of the furnace shell 1 on the outer side of the furnace shell 1, and the multiple sets of vertical connecting pipes 39 being connected by annular pipes. The connecting pipes 39 are evenly distributed on the outer side of the furnace shell 1. Air outlets 40 are installed on the outer wall of the connecting pipes 39, and the air outlets 40 penetrate the outer wall of the furnace shell 1 and extend into the interior of the furnace shell 1. The air outlets 40 are located outside the cooling pipes 37. A fan 38 is installed on the outer side of the furnace shell 1, and the air outlet of the fan 38 is connected to the bottom end of a set of connecting pipes 39. The heat preservation unit 36 ​​includes a first heat preservation plate 42, a second heat preservation plate 43, and a third heat preservation plate 44. The connecting end 32 penetrates the outer wall of the annular heat preservation plate 42, and the first heat preservation plate 42 is located outside the hot end 33. Adjacent sets of heat preservation units 36 are connected to each other. Annular insulation board 2 43 is connected between the first and second insulation boards 42. A through groove 1 48 is opened through the outer wall of insulation board 2 43. Annular insulation board 3 44 is fitted on the outer wall of insulation board 2 43. A through groove 2 49 is opened through the outer wall of insulation board 3 44. The area of ​​through groove 2 49 is slightly smaller than the area of ​​through groove 1 48. Adjacent sets of insulation board 3 44 are connected by a connecting strip. The connecting strip is located between the two connecting ends 32 on both sides of the furnace body 3. A worm gear 45 is fitted on the outer wall of the lowest set of insulation board 3 44. A support plate is provided on the outer wall of the furnace shell 1. A servo motor 2 46 is installed on the top of the support plate. A worm 47 is connected to the output end of the servo motor 2 46. The worm 47 meshes with the worm gear 45. A connecting pipe 50 is installed through the bottom of the furnace shell 1. A sealing valve is installed on the connecting pipe 50.

[0052] Furthermore, when rapid cooling of the furnace body 3 is required, the servo motor 46 drives the worm gear 47 to rotate, which in turn drives the worm wheel 45 to rotate. This causes the worm wheel 45 to drive the insulation plate 44 to rotate synchronously. The insulation plate 44 rotates along the outer wall of the insulation plate 43, causing the through groove 49 on the insulation plate 44 to overlap with the through groove 48 on the insulation plate 43. This makes the insulation unit 36 ​​appear hollow, opens the sealing valve on the connecting pipe 50, and injects coolant into the cooling pipe 37. Airflow is generated, transported, and blown out by the fan 38, connecting pipe 39, and air outlet 40, respectively. After being cooled by the cooling pipe 37, the airflow passes through the through groove 48 and through groove 49 and is blown onto the surface of the furnace body 3 to cool the furnace body 3. The air inside the furnace shell 1 is also discharged through the connecting pipe 50 to ensure airflow between the furnace shell 1 and the furnace body 3, thus achieving the purpose of rapid cooling of the furnace body 3.

[0053] Working principle: The raw materials for beryllium copper alloy preparation are added to the furnace body 3, the furnace cover 2 is closed, and the vacuum pump 30 is started to maintain a vacuum state inside the furnace body 3 for alloy preparation. The induction coil 4 is energized to generate an alternating magnetic field, which heats and melts the raw materials inside the furnace body 3 and promotes the flow of the raw materials. During the alloy production process, the temperature detection unit 5 detects the alloy temperature. When temperature stratification occurs, the hollow rod 8 rotates, driving the first arc plate 9 and the second arc plate 11 to rotate until they are separated from the inner wall of the furnace body 3. Then, the rotating motor 26 drives the rotating frame 27 to rotate, causing the rotating frame 27 to push the second arc plate 11 to rotate to an inclined state. The inclined arc plate 11 guides the alloy raw materials and adjusts the flow path of the alloy raw materials. The furnace shell 1 is heated by a uniform module to guide the flow of raw materials. During the alloy melting process, the temperature inside the furnace shell 1 rises. The heat energy between the furnace shell 1 and the furnace body 3 is converted into electrical energy by the conversion unit, and then transmitted and stored in the energy management unit 34. The energy management unit 34 provides electrical energy to the heating plate 35, so that the heating plate 35 can provide auxiliary heating to the raw materials inside the furnace body 3. When it is necessary to dissipate heat from the furnace body 3, the insulation plate 34 is driven to rotate, so that the through groove 2 49 on the insulation plate 34 is aligned with the through groove 1 48 on the insulation plate 2 43, so that the insulation unit 36 ​​is hollow. Then, by outputting coolant into the cooling pipe 37 and starting the fan 38 to blow air into the furnace shell 1, the furnace body 3 is cooled.
