Description

Technical Field

[0001] The present invention relates to the technical field of remelting equipment, and specifically relates to a dual-heat-source remelting production equipment and its production method. Background Art

[0002] In the field of metal ingot production, the disadvantages of traditional single-heat-source remelting equipment are prominent. Taking electroslag remelting as an example, although it can improve the purity of metals, relying solely on resistance heat, the heating area is limited, the temperature gradient is large, which is likely to cause composition segregation of metal ingots and poor internal tissue uniformity. For ordinary electric arc furnaces, the melting efficiency is limited, it is difficult to efficiently remelt high-melting-point metals, and the impurity removal effect is not good. With the soaring quality requirements of high-end industries such as aerospace for metal ingots, materials with more uniform structures and higher purities are needed. To overcome these problems, dual-heat-source remelting metal ingot production equipment has emerged. By coordinating two heat sources, the temperature field and flow field are optimized, significantly improving the quality and production efficiency of metal ingots.

[0003] In the dual-heat-source remelting production equipment, during the melting process of the consumable electrode in the equipment, the contact surface between the consumable electrode and the slag pool may change, causing the electric arc to concentrate, resulting in local overheating. The consumable electrode may be melted due to local overheating, causing the consumable electrode to disconnect from the slag liquid, resulting in the interruption of the remelting process and a reduction in production efficiency. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a dual-heat-source remelting production equipment, including a housing, a bracket is fixedly connected to the outer wall of the housing, and further includes: A preheating mechanism, the outer wall of the preheating mechanism is slidably connected to the inner wall of the housing, and the preheating mechanism is used to preheat the remelting metal; A protection mechanism, the outer wall of the protection mechanism is fixedly connected to the inner wall of the housing, and the protection mechanism is used to protect the remelting metal from melting; An output mechanism, the outer wall of the output mechanism is fixedly connected to the inner wall of the preheating mechanism, and the output mechanism is used to output the molten metal; A consumable electrode is slidably connected to the inner wall of the housing, an inner cavity housing is fixedly connected to the inner wall of the housing, a plurality of heat dissipation fins are fixedly connected to the outer wall of the inner cavity housing, and a sliding housing is slidably connected to the inner wall of the inner cavity housing, and a central cavity is provided at the central axis of the sliding housing.

[0005] Preferably, the preheating mechanism includes: A preheating component, the outer wall of the preheating component is fixedly connected to the inner wall of the sliding housing.

[0006] Preferably, the protection mechanism includes: A transmission component, the outer wall of the transmission component is fixedly connected to the inner wall of the housing; The sliding component is slidably connected to the inner wall of the transmission component at the outer wall of the sliding component.

[0007] Preferably, the output mechanism includes: The output component is fixedly connected to the inner wall of the inner cavity housing at the outer wall of the output component; The speed control component is rotatably connected to the inner wall of the output component at the outer wall of the speed control component.

[0008] Preferably, the preheating component includes a plurality of support rods fixedly connected to the inner wall of the sliding housing. The top outer walls of the plurality of support rods are fixedly connected with induction coils. Two contact electrodes are slidably connected to the outer wall of the induction coil; The outer wall of the contact electrode is fixedly connected to the inner wall of the inner cavity housing.

[0009] As the remelting process progresses, more and more molten metal accumulates above the protective housing. At this time, due to the drive of the support arm, the consumable electrode will rise as the molten metal inside the inner cavity housing rises. At this time, the set sliding housing will rise as the metal liquid level rises. When the consumable electrode rises, the power supply connected to the contact electrode is started, so that the induction coil inside the sliding housing is energized. Using electromagnetic induction, eddy currents are generated in the consumable electrode, and electrical energy is converted into heat energy through resistive losses. Before the consumable electrode is heated and melted by the arc, the consumable electrode is preheated by the induced current. As the consumable electrode gradually melts and the metal liquid level inside the inner cavity housing gradually rises, the sliding housing will move as the metal liquid level inside the inner cavity housing rises, so that the induction coil arranged inside the sliding housing can move with the movement of the consumable electrode, and the consumable electrode can be preheated in time, which can help the arc remelting starting process to be smoother, shorten the starting time, and improve the remelting efficiency; Preferably, the transmission component includes a high-voltage output cavity opened on the inner wall of the housing. A high-voltage gas pipe is fixedly connected to the outer wall of the high-voltage output cavity. A support arm is fixedly connected to the outer wall of the bracket. A high-voltage input cavity is opened on the inner wall of the support arm; The outer wall of the end of the high-voltage gas pipe away from the high-voltage output cavity is fixedly connected to the inner wall of the high-voltage input cavity.

[0010] Preferably, the sliding component includes a sliding plate slidably connected to the inner wall of the support arm. A dummy electrode is fixedly connected to the inner wall of the sliding plate. A closing plate is fixedly connected to the inner wall of the support arm; The bottom outer wall of the dummy electrode is fixedly connected to the top outer wall of the consumable electrode.

[0011] In use, first fix the outer wall of the top of the consumable electrode to the outer wall of the bottom of the dummy electrode. Then fill the gap between the sliding outer shell and the protective outer shell with solid slag material. After that, start the motor inside the support arm, so that the motor drives the movement towards the outer shell. At this time, driven by the support arm, the sliding plate on its inner wall will drive the dummy electrode to move towards the outer shell. The bottom of the dummy electrode is fixed with the consumable electrode, so that the consumable electrode enters the interior of the outer shell; Due to the high temperature generated during the remelting process, the gas inside the device will be pressurized, so that the air pressure inside the inner cavity outer shell increases. At this time, the high-pressure gas reaches the cavity between the sliding plate and the closing plate through the high-pressure output cavity, the high-pressure gas pipe and the high-pressure input cavity. The presence of the high-pressure gas will cause the sliding plate to move away from the outer shell, and the movement of the sliding plate will drive the dummy electrode to move together. During the remelting process, due to various factors, the arc power is too large, causing the consumable electrode to melt, resulting in the interruption of the remelting process. At this time, due to the interruption of the remelting process, the gas pressure inside the device will decrease, so that the sliding plate will drive the dummy electrode to move towards the inside of the inner cavity outer shell, so that the consumable electrode continues to carry out the remelting reaction with the slag pool inside the inner cavity outer shell, thus reducing the impact of the melting of the consumable electrode caused by various factors on the remelting process, thereby improving the remelting efficiency of the device; Preferably, the output assembly includes a protective outer shell fixedly connected to the inner wall of the inner cavity outer shell. A striking body is slidably connected to the inner wall of the protective outer shell. A plurality of connecting rods are rotatably connected to the outer wall of the striking body. An opening and closing cover is rotatably connected to the inner walls of the plurality of connecting rods. An output cylinder is fixedly connected to the inner wall of the protective outer shell. A fixed rod is rotatably connected to the central axes of the plurality of connecting rods; The outer wall of the opening and closing cover is slidably connected to the outer wall of the protective outer shell. The outer walls of the plurality of fixed rods are fixedly connected to the inner wall of the protective outer shell.

[0012] When the bottom of the consumable electrode reaches the top of the striking body, at this time, start the power supply connected between the dummy electrode and the striking body, so that the current flows through the slag material and the consumable electrode. Since the molten slag has a high resistance, a large amount of resistive heat will be generated when the current passes through. With the accumulation of heat, the end of the consumable electrode is gradually heated to the molten state, forming liquid metal drops. These metal drops fall off from the electrode end under the action of gravity, pass through the high-temperature molten slag pool and drip downward. At this time, the molten metal will gradually accumulate on the top of the protective outer shell; As the remelting process progresses, the metal liquid level gradually rises. Due to the gradual increase in the metal liquid, the pressure on the arc starting body gradually increases. When the metal liquid increases to a certain extent, the arc starting body will move downward. At this time, the movement of the arc starting body will cause the rotational connection between the connecting rod and the arc starting body to move downward with the arc starting body. Due to the existence of the fixed rod, the connection between the connecting rod and the opening / closing cover will move upward, thereby driving the opening / closing cover to move upward, so that the melted metal liquid flows into the lower crystallization chamber through the output cylinder. At this time, the inner cavity housing and the inner wall of the housing are filled with coolant, and through contact with the heat dissipation fins, the metal liquid of the protective housing and the inner cavity housing is cooled and solidified; Preferably, the speed control component includes an upper limiting plate rotatably connected to the inner wall of the output cylinder. An upper special-shaped gear is fixedly connected to the outer wall of the upper limiting plate. A lower special-shaped gear is meshed and connected to the outer wall of the upper special-shaped gear. A lower limiting plate is fixedly connected to the inner wall of the lower special-shaped gear; the outer wall of the lower limiting plate is rotatably connected to the inner wall of the output cylinder; When the metal liquid flows out through the output cylinder, it will contact the upper limiting plate and the lower limiting plate provided on the inner wall of the output cylinder. The lengths and angles of the upper limiting plate and the lower limiting plate extending out of the output cylinder are different. When the amount of metal liquid produced in the inner cavity housing increases, the metal liquid contacting the upper limiting plate will rotate downward. The upper limiting plate will drive the upper special-shaped gear to rotate, thereby driving the lower special-shaped gear to rotate in the opposite direction. The rotation of the lower special-shaped gear will drive the lower limiting plate to rotate, so that the upper limiting plate and the lower limiting plate rotate in the opposite direction. Since the length of the lower limiting plate is longer than that of the upper limiting plate, when the lower limiting plate rotates upward, the flow of the metal liquid inside the output cylinder is restricted. When the lower limiting plate rotates upward, more metal liquid is contacted, so that the lower limiting plate will rotate downward, and then drive the upper limiting plate to rotate in the opposite direction, so that when the metal liquid flows through the inside of the output cylinder, its flow rate will be restricted by the upper limiting plate and the lower limiting plate. When the flow rate of the metal liquid increases, the rotation frequency of the upper limiting plate and the lower limiting plate increases, thereby controlling the flow rate of the metal liquid to a certain extent, ensuring the stability in the production process, and improving the production efficiency.

[0013] A production method of a double-heat-source remelting production device includes the following steps, S1: Install the device: When in use, first place the device in a suitable position, and fixedly connect the metal rod to be remelted to the outer wall of the bottom of the false electrode; S2: Start the device: When in use, start the motor on the inner wall of the support arm to drive the support arm to start remelting.

[0014] The present invention has the following beneficial effects: (1)The present invention is provided with a protection mechanism to solve the problem that the electrode is melted due to excessive arc power caused by various factors, resulting in the interruption of the remelting process and thus reducing the production efficiency. During the remelting process, the high temperature generated will pressurize the gas inside the device, thereby increasing the air pressure inside the inner cavity housing. At this time, the high-pressure gas reaches the cavity between the sliding plate and the closing plate through the high-pressure output cavity, the high-pressure gas pipe, and the high-pressure input cavity. The presence of the high-pressure gas will cause the sliding plate to move away from the housing, and the movement of the sliding plate will drive the dummy electrode to move together. During the remelting process, due to various factors, the arc power is too large, causing the consumable electrode to melt, resulting in the interruption of the remelting process. At this time, due to the interruption of the remelting process, the gas pressure inside the device will decrease, causing the sliding plate to drive the dummy electrode to move into the inner cavity housing, so that the consumable electrode continues to carry out a remelting reaction with the slag pool inside the inner cavity housing, thereby reducing the impact of the melting of the consumable electrode caused by various factors on the remelting process, and thus improving the remelting efficiency of the device; (2)The present invention is provided with an output component to solve the problem that solid bridging is formed between the metal liquid and the electrode and the crystallization pool during the solidification of the metal liquid, blocking the normal droplet transfer and resulting in the interruption of the remelting process. As the remelting process progresses, the metal liquid level gradually rises. Due to the gradual increase in the metal liquid, the pressure on the arc starter gradually increases. When the metal liquid increases to a certain extent, the arc starter will move downward. At this time, the movement of the arc starter will cause the rotational connection between the connecting rod and the arc starter to move downward with the arc starter. Due to the presence of the fixed rod, the connection between the connecting rod and the opening and closing cover will move upward, thereby driving the opening and closing cover to move upward, so that the melted metal liquid flows into the lower crystallization chamber through the output cylinder. At this time, the inner cavity housing and the inner wall of the housing are filled with coolant. Through contact with the heat dissipation fins, the metal liquid of the protective housing and the inner cavity housing is cooled and solidified, reducing the probability of solid bridging formed between the solidified metal liquid and the electrode and the crystallization pool, blocking the normal droplet transfer, and resulting in the interruption of the remelting process, and improving the production efficiency; (3) To address the impact caused by the unstable flow rate of the molten metal when it enters the crystallization chamber, a too fast speed may lead to uneven crystallization, gas pores or shrinkage porosity, while a too slow speed will affect production efficiency and even cause premature solidification of the molten metal. The device is provided with a speed control component. When the molten metal flows out through the output cylinder, it will contact the upper limiting plate and the lower limiting plate arranged on the inner wall of the output cylinder. The lengths and angles of the upper limiting plate and the lower limiting plate extending out of the output cylinder are different. When the amount of molten metal produced in the inner cavity shell increases, the molten metal contacts the upper limiting plate and rotates downward. The upper limiting plate will drive the upper special-shaped gear to rotate, thereby driving the lower special-shaped gear to rotate in the opposite direction. The rotation of the lower special-shaped gear will drive the lower limiting plate to rotate, so that the upper limiting plate and the lower limiting plate rotate in the opposite direction. Since the length of the lower limiting plate is longer than that of the upper limiting plate, when the lower limiting plate rotates upward, the flow of the molten metal inside the output cylinder is restricted. When the lower limiting plate rotates upward, more molten metal is contacted, so that the lower limiting plate will rotate downward, and then drive the upper limiting plate to rotate in the opposite direction. Thus, when the molten metal flows through the inside of the output cylinder, its flow rate will be restricted by the upper limiting plate and the lower limiting plate. When the flow rate of the molten metal increases, the rotation frequency of the upper limiting plate and the lower limiting plate speeds up, thereby controlling the flow rate of the molten metal to a certain extent, ensuring the stability in the production process and improving the production efficiency; (4) To solve the problem that the solidified molten metal forms a solid bridge between the electrode and the crystallization pool, blocking the normal droplet transfer and causing the remelting process to interrupt, the device is provided with an output component. As the remelting process progresses, the liquid metal level gradually rises. Due to the gradual increase in the molten metal, the pressure on the arc starter gradually increases. When the molten metal increases to a certain extent, the arc starter will move downward. At this time, the movement of the arc starter will cause the rotational connection between the connecting rod and the arc starter to move downward with the arc starter. Due to the existence of the fixed rod, the connection between the connecting rod and the opening and closing cover will move upward, thereby driving the opening and closing cover to move upward, so that the melted molten metal flows into the lower crystallization chamber through the output cylinder. At this time, the inner cavity shell and the inner wall of the outer shell are filled with coolant. Through contact with the heat dissipation fins, the molten metal of the protective shell and the inner cavity shell is cooled and solidified, reducing the probability that the solidified molten metal forms a solid bridge between the electrode and the crystallization pool, blocking the normal droplet transfer and causing the remelting process to interrupt, and improving the production efficiency.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Example 1. Please refer to Figure 1 - Figure 12 , the present invention is a double heat source remelting production device, including a housing 13, a bracket 14 is fixedly connected to the outer wall of the housing 13, and further includes: A preheating mechanism 1, the outer wall of the preheating mechanism 1 is slidably connected to the inner wall of the housing 13, and the preheating mechanism 1 is used for preheating the remelting metal; A protection mechanism 2, the outer wall of the protection mechanism 2 is fixedly connected to the inner wall of the housing 13, and the protection mechanism 2 is used for protecting the remelting metal from fusing; An output mechanism 3, the outer wall of the output mechanism 3 is fixedly connected to the inner wall of the preheating mechanism 1, and the output mechanism 3 is used for outputting molten metal; A consumable electrode 111 is slidably connected to the inner wall of the housing 13, an inner cavity housing 112 is fixedly connected to the inner wall of the housing 13, a plurality of heat dissipation fins 113 are fixedly connected to the outer wall of the inner cavity housing 112, a sliding housing 114 is slidably connected to the inner wall of the inner cavity housing 112, and a central cavity 115 is provided at the central axis of the sliding housing 114.

[0020] The preheating mechanism 1 includes: A preheating component 12, the outer wall of the preheating component 12 is fixedly connected to the inner wall of the sliding housing 114.

[0021] The protection mechanism 2 includes: A transmission component 21, the outer wall of the transmission component 21 is fixedly connected to the inner wall of the housing 13; A sliding component 22, the outer wall of the sliding component 22 is slidably connected to the inner wall of the transmission component 21.

[0022] The output mechanism 3 includes: An output component 31, the outer wall of the output component 31 is fixedly connected to the inner wall of the inner cavity housing 112; A speed control component 32, the outer wall of the speed control component 32 is rotatably connected to the inner wall of the output component 31.

[0023] The preheating component 12 includes a plurality of support rods 121 fixedly connected to the inner wall of the sliding housing 114, an induction coil 122 is fixedly connected to the outer wall of the plurality of support rods 121, and two contact electrodes 123 are slidably connected to the outer wall of the induction coil 122; The outer wall of the contact electrode 123 is fixedly connected to the inner wall of the inner cavity housing 112.

[0024] As the remelting process progresses, more and more molten metal accumulates above the protective casing 311. At this time, driven by the support arm 213, the consumable electrode 111 rises as the molten metal inside the inner cavity casing 112 rises. At this time, the arranged sliding casing 114 rises as the molten metal level rises. When the consumable electrode 111 rises, the power supply connected to the contact electrode 123 is started, so that the induction coil 122 inside the sliding casing 114 is energized. Using electromagnetic induction, eddy currents are generated in the consumable electrode 111, and electrical energy is converted into heat energy through resistive losses. Before the consumable electrode 111 is heated and melted by the arc, the consumable electrode 111 is preheated by the induced current. As the consumable electrode 111 gradually melts and the molten metal level inside the inner cavity casing 112 gradually rises, the sliding casing 114 moves as the molten metal level inside the inner cavity casing 112 rises, so that the induction coil 122 arranged inside the sliding casing 114 can move as the consumable electrode 111 moves, and the consumable electrode 111 can be preheated in time, which can help the arc remelting starting process to be smoother, shorten the starting time, and improve the remelting efficiency; Embodiment 2, please refer to Figure 1 - Figure 12 , the present invention is a double-heat-source remelting production device. On the basis of Embodiment 1, the transmission assembly 21 includes a high-voltage output cavity 211 opened on the inner wall of the casing 13. A high-voltage gas pipe 212 is fixedly connected to the outer wall of the high-voltage output cavity 211. A support arm 213 is fixedly connected to the outer wall of the support 14. A high-voltage input cavity 214 is opened on the inner wall of the support arm 213; One end of the high-voltage gas pipe 212 far from the high-voltage output cavity 211 is fixedly connected to the inner wall of the high-voltage input cavity 214.

[0025] The sliding assembly 22 includes a sliding plate 221 slidably connected to the inner wall of the support arm 213. A dummy electrode 222 is fixedly connected to the inner wall of the sliding plate 221. A closing plate 223 is fixedly connected to the inner wall of the support arm 213; The bottom outer wall of the dummy electrode 222 is fixedly connected to the top outer wall of the consumable electrode 111.

[0026] During use, first fix the top outer wall of the consumable electrode 111 to the bottom outer wall of the dummy electrode 222, then fill the solid slag into the gap between the sliding casing 114 and the protective casing 311, and then start the motor inside the support arm 213, so that the motor drives 213 to move towards the casing 13. At this time, driven by the support arm 213, the sliding plate 221 on its inner wall will drive the dummy electrode 222 to move towards the casing 13. The bottom of the dummy electrode 222 is fixed with the consumable electrode 111, so that the consumable electrode 111 enters the inside of the casing 13; Due to the high temperature generated during the remelting process, the gas inside the device will be pressurized, causing the air pressure inside the inner cavity housing 112 to increase. At this time, the high-pressure gas reaches the cavity between the sliding plate 221 and the closing plate 223 through the high-pressure output cavity 211, the high-pressure gas pipe 212, and the high-pressure input cavity 214. The presence of the high-pressure gas causes the sliding plate 221 to move away from the housing 13, and the movement of the sliding plate 221 drives the dummy electrode 222 to move together. During the remelting process, due to various factors, the arc power is too large, causing the consumable electrode 111 to melt, resulting in the interruption of the remelting process. At this time, due to the interruption of the remelting process, the gas pressure inside the device decreases, causing the sliding plate 221 to drive the dummy electrode 222 to move into the inner cavity housing 112, enabling the consumable electrode 111 to continue the remelting reaction with the slag pool inside the inner cavity housing 112, thereby reducing the impact of the interruption of the remelting process caused by the melting of the consumable electrode 111 due to various factors, and thus improving the remelting efficiency of the device; The output component 31 includes a protective housing 311 fixedly connected to the inner wall of the inner cavity housing 112. A striking body 312 is slidably connected to the inner wall of the protective housing 311. A plurality of connecting rods 313 are rotatably connected to the outer wall of the striking body 312. An opening and closing cover 314 is rotatably connected to the inner walls of the plurality of connecting rods 313. An output cylinder 315 is fixedly connected to the inner wall of the protective housing 311. A fixed rod 316 is rotatably connected to the central axes of the plurality of connecting rods 313; The outer wall of the opening and closing cover 314 is slidably connected to the outer wall of the protective housing 311. The outer walls of the plurality of fixed rods 316 are fixedly connected to the inner wall of the protective housing 311.

[0027] When the bottom of the consumable electrode 111 reaches the top of the striking body 312, the power supply connected between the dummy electrode 222 and the striking body 312 is started at this time, causing the current to flow through the slag material and the consumable electrode 111. Since the molten slag has a high resistance, a large amount of resistive heat is generated when the current passes through. With the accumulation of heat, the end of the consumable electrode 111 is gradually heated to the molten state, forming liquid metal drops. These metal drops fall off from the electrode end under the action of gravity, pass through the high-temperature molten slag pool and drip downward. At this time, the molten metal will gradually accumulate on the top of the protective housing 311; As the remelting process progresses, the metal liquid level gradually rises. Due to the gradual increase in the metal liquid, the pressure on the arc starter 312 gradually increases. When the metal liquid increases to a certain extent, the arc starter 312 will move downward. At this time, the movement of the arc starter 312 will cause the rotational connection between the connecting rod 313 and the arc starter 312 to move downward with the arc starter 312. Due to the existence of the fixed rod 316, the connection between the connecting rod 313 and the opening / closing cover 314 will move upward, thereby driving the opening / closing cover 314 to move upward, so that the melted metal liquid flows into the lower crystallization chamber through the output cylinder 315. At this time, the inner cavity housing 112 and the inner wall of the housing 13 are filled with coolant. Through contact with the heat dissipation fins 113, the metal liquid of the protective housing 311 and the inner cavity housing 112 is cooled and solidified; The speed control component 32 includes an upper limiting plate 321 rotatably connected to the inner wall of the output cylinder 315. An upper special-shaped gear 322 is fixedly connected to the outer wall of the upper limiting plate 321. A lower special-shaped gear 323 is meshed and connected to the outer wall of the upper special-shaped gear 322. A lower limiting plate 324 is fixedly connected to the inner wall of the lower special-shaped gear 323; The outer wall of the lower limiting plate 324 is rotatably connected to the inner wall of the output cylinder 315; When the metal liquid flows out through the output cylinder 315, it will contact the upper limiting plate 321 and the lower limiting plate 324 provided on the inner wall of the output cylinder 315. The lengths and angles of the upper limiting plate 321 and the lower limiting plate 324 extending out of the output cylinder 315 are different. When the amount of metal liquid produced in the inner cavity housing 112 increases, the metal liquid contacting the upper limiting plate 321 will rotate downward. The upper limiting plate 321 will drive the upper special-shaped gear 322 to rotate, thereby driving the lower special-shaped gear 323 to rotate in the opposite direction. The rotation of the lower special-shaped gear 323 will drive the lower limiting plate 324 to rotate, so that the upper limiting plate 321 and the lower limiting plate 324 rotate in the opposite direction. Since the length of the lower limiting plate 324 is longer than that of the upper limiting plate 321, when the lower limiting plate 324 rotates upward, the flow of the metal liquid inside the output cylinder 315 is restricted. When the lower limiting plate 324 rotates upward, more metal liquid is contacted, so that the lower limiting plate 324 will rotate downward, and then drive the upper limiting plate 321 to rotate in the opposite direction. Thus, when the metal liquid flows through the inside of the output cylinder 315, its flow rate will be restricted by the upper limiting plate 321 and the lower limiting plate 324. When the flow rate of the metal liquid increases, the rotation frequency of the upper limiting plate 321 and the lower limiting plate 324 increases, thereby controlling the flow rate of the metal liquid to a certain extent, ensuring the stability in the production process, and improving the production efficiency.

[0028] A production method of a double heat source remelting production device includes the following steps, S1: Install the device: When in use, first place the device in a suitable position and fixedly connect the metal rod to be remelted to the outer wall of the bottom of the dummy electrode 222; S2: Start the device: When in use, start the motor on the inner wall of the support arm 213 to drive the support arm 213 to start remelting.

[0029] A specific application of this embodiment is: When in use, first fix the outer wall of the top of the consumable electrode 111 to the outer wall of the bottom of the dummy electrode 222, then fill the solid slag into the gap between the sliding outer shell 114 and the protective outer shell 311, and then start the motor inside the support arm 213 to make the motor drive 213 to move towards the outer shell 13. At this time, driven by the support arm 213, the sliding plate 221 on its inner wall will drive the dummy electrode 222 to move towards the outer shell 13. The bottom of the dummy electrode 222 is fixed to the consumable electrode 111, so that the consumable electrode 111 enters the inside of the outer shell 13; When the bottom of the consumable electrode 111 reaches the top of the arc starter 312, at this time, start the power supply connected between the dummy electrode 222 and the arc starter 312, so that the current flows through the slag and the consumable electrode 111. Since the molten slag has a high resistance, a large amount of resistive heat will be generated when the current passes through. As the heat accumulates, the end of the consumable electrode 111 is gradually heated to the molten state, forming liquid metal drops. These metal drops fall off from the electrode end under the action of gravity and drip downward through the high-temperature molten slag pool. At this time, the molten metal will gradually accumulate on the top of the protective outer shell 311. As the remelting process proceeds, more and more molten metal accumulates above the protective outer shell 311. At this time, driven by the support arm 213, the consumable electrode 111 will rise as the molten metal in the inner cavity outer shell 112 rises. At this time, the set sliding outer shell 114 will rise as the molten metal surface rises. When the consumable electrode 111 rises, start the power supply connected to the contact electrode 123 to make the induction coil 122 inside the sliding outer shell 114 energized. Utilize electromagnetic induction to make the consumable electrode 111 generate eddy currents, convert electrical energy into heat energy through resistive losses, preheat the consumable electrode 111 before it is heated and melted by the arc through the induced current. As the consumable electrode 111 gradually melts and the molten metal surface inside the inner cavity outer shell 112 gradually rises, the sliding outer shell 114 will move as the molten metal surface inside the inner cavity outer shell 112 rises, so that the induction coil 122 arranged inside the sliding outer shell 114 can move as the consumable electrode 111 moves, and can preheat the consumable electrode 111 in time, thus helping the arc remelting starting process to be smoother, shortening the starting time, and improving the remelting efficiency; Due to the high temperature generated during the remelting process, the gas inside the device will be pressurized, causing the air pressure inside the inner cavity housing 112 to increase. At this time, the high-pressure gas reaches the cavity between the sliding plate 221 and the closing plate 223 through the high-pressure output cavity 211, the high-pressure gas pipe 212, and the high-pressure input cavity 214. The presence of the high-pressure gas causes the sliding plate 221 to move away from the housing 13, and the movement of the sliding plate 221 drives the dummy electrode 222 to move together. During the remelting process, due to various factors, the arc power is too large, causing the consumable electrode 111 to melt, resulting in the interruption of the remelting process. At this time, due to the interruption of the remelting process, the gas pressure inside the device decreases, causing the sliding plate 221 to drive the dummy electrode 222 to move into the inner cavity housing 112, enabling the consumable electrode 111 to continue the remelting reaction with the slag pool inside the inner cavity housing 112. This reduces the impact of the melting of the consumable electrode 111 caused by various factors on the remelting process, thereby improving the remelting efficiency of the device; As the remelting process progresses, the metal liquid level gradually rises. Due to the gradual increase in the metal liquid, the pressure on the arc starter 312 gradually increases. When the metal liquid increases to a certain extent, the arc starter 312 moves downward. At this time, the movement of the arc starter 312 causes the rotational connection between the connecting rod 313 and the arc starter 312 to move downward with the arc starter 312. Due to the presence of the fixed rod 316, the connection between the connecting rod 313 and the opening and closing cover 314 moves upward, driving the opening and closing cover 314 to move upward. As a result, the melted metal liquid flows into the lower crystallization chamber through the output cylinder 315. At this time, the inner wall of the inner cavity housing 112 and the housing 13 is filled with coolant. Through contact with the heat dissipation fins 113, the metal liquid of the protective housing 311 and the inner cavity housing 112 is cooled and solidified; When the molten metal flows out through the output cylinder 315, it will contact the upper limiting plate 321 and the lower limiting plate 324 provided on the inner wall of the output cylinder 315. The lengths and angles of the upper limiting plate 321 and the lower limiting plate 324 extending out of the output cylinder 315 are different. When the amount of molten metal produced in the inner cavity housing 112 increases, the molten metal contacting the upper limiting plate 321 will rotate downward. The upper limiting plate 321 will drive the upper special-shaped gear 322 to rotate, thereby driving the lower special-shaped gear 323 to rotate in the opposite direction. The rotation of the lower special-shaped gear 323 will drive the lower limiting plate 324 to rotate, so that the upper limiting plate 321 and the lower limiting plate 324 rotate in the opposite direction. Since the length of the lower limiting plate 324 is longer than that of the upper limiting plate 321, when the lower limiting plate 324 rotates upward, the flow of the molten metal inside the output cylinder 315 is restricted. When the lower limiting plate 324 rotates upward, more molten metal is contacted, so that the lower limiting plate 324 will rotate downward, and then drive the upper limiting plate 321 to rotate in the opposite direction. Thus, when the molten metal flows through the inside of the output cylinder 315, its flow rate will be restricted by the upper limiting plate 321 and the lower limiting plate 324. When the flow rate of the molten metal increases, the rotation frequency of the upper limiting plate 321 and the lower limiting plate 324 speeds up, thereby controlling the flow rate of the molten metal to a certain extent, ensuring the stability in the production process and improving the production efficiency.
