Description

Technical Field

[0001] This application belongs to the field of cryogenic engineering equipment technology, and in particular relates to a rapid cooling device for the preparation of amorphous alloys. Background Technology

[0002] In daily life, people generally encounter two types of materials: crystalline materials and amorphous materials. Materials with irregular internal atomic arrangements are amorphous materials. While most metals are crystalline in their normal state, when a metal melts, its internal atoms are in an active state. If the cooling rate is too fast during the cooling process, the atoms may not have time to arrange themselves in an orderly manner before solidifying, thus becoming an amorphous alloy.

[0003] Existing methods for preparing amorphous alloys include rapid solidification or melt rotation. The principle involves spraying molten magnesium alloy from a crucible through a nozzle onto a high-speed rotating quenching roller. The solution to be cooled is then subjected to centrifugal force generated by the high-speed spinning of the quenching roller, forming an amorphous ribbon. In the preparation of amorphous magnesium alloys, the cooling rate is a crucial factor determining the amorphization of the magnesium alloy.

[0004] Traditional rapid cooling technologies for amorphous magnesium alloys employ either air-cooling or water-cooling methods, both of which yield poor cooling results and cannot achieve the recycling of coolant. Because traditional liquid nitrogen usage is mostly one-time consumption, such as direct spraying or vaporization followed by discharge, at least 70% of cryogenic resources are not recovered, resulting in widespread waste of cooling capacity. Furthermore, existing liquid nitrogen storage equipment suffers from low cooling capacity utilization and insufficient temperature control precision, failing to meet high-precision requirements. In traditional amorphous magnesium alloy preparation, the excessively rapid cooling rate prevents the regular arrangement of atomic structures. This device utilizes induction melting equipment to melt the raw materials and sprays the molten liquid through specific nozzles onto a high-speed rotating copper roller to prepare amorphous ribbons or powders.

The detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application. The described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments in this application, they can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] This application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Please refer to Figure 1 and Figure 2 This application provides a rapid cooling device 100 for amorphous alloy preparation, comprising: a spiral tube 120, a rapid cooling roller 110, two connectors 130, a driving device 180, and a cold source circulation unit. The spiral tube 120 has a spirally wound pipe 121 forming a central channel 122. Both ends of the pipe 121 are respectively provided with nozzles 123 for injecting amorphous alloy raw materials. The amorphous alloy raw materials enter the pipe 121 through the nozzles 123 and are swung into a strip shape under centrifugal force to form amorphous alloy thin strips, thus preventing the amorphous alloy from oxidizing upon contact with air. To enhance the cooling effect and structural hardness, the spiral tube 120 is also made of a heat-conducting material, such as copper. A copper sleeve can be installed inside the central channel 122 of the pipe 121, and the rapid cooling roller 110 is placed inside the copper sleeve. The rapid cooling roller 110 is a tube structure made of a heat-conducting material, such as a copper tube. The two ends of the quench roller 110 are internally connected to form a hollow channel. The inside and both ends of the quench roller 110 are not sealed. This channel is used to introduce a cold source and exchange heat with the spiral tube 120 to achieve rapid cooling and reduce the temperature of the spiral tube 120 to the production requirement. Two joints 130 are respectively connected to the two ends of the spiral tube 120 and rotatably connected to the two ends of the quench roller 110. Bearings can be installed at both ends of the quench roller 110 and fixed to the joints 130 by the bearings. Buckles can be fixed to the outside of the bearings to form a rotatable connection and reduce frictional heat generation by using the buckles. The driving device 180 is connected to the quench roller 110 to drive the quench roller 110 to rotate. The driving device 180 adopts existing conventional devices that can drive the quench roller 110. The cold source circulation unit is respectively connected to the two joints 130 to circulate the cold source in the quench roller 110. The cold source can be cold water, cold air or liquid nitrogen. In order to improve the cooling effect, this application uses liquid nitrogen as an example for description.

[0032] Existing technology devices have poor cooling effects in the formation of amorphous alloys. This application provides a spiral flow channel for the formation of amorphous alloys through a spiral tube 120. The spiral structure increases the contact area between the spiral tube 120 and the quenching roller 110. At the same time, it can drive the raw material of amorphous alloys to be swung into a strip shape under the action of centrifugal force. A cold source is introduced into the quenching roller 110, and the quenching roller 110 is a tube structure with good thermal conductivity. The cold source circulation unit provides continuous circulating cold energy to the quenching roller 110. In this way, the quenching roller 110 can provide a large amount of cold energy to the spiral tube 120. The driving device 180 drives the quenching roller 110 to rotate. The quenching roller 110 has a certain speed, which increases the contact between the cold source and the spiral tube 120 per unit time, thereby enhancing the heat dissipation effect, achieving efficient heat exchange, effectively improving the cooling effect of amorphous alloy forming, and realizing rapid cooling of amorphous alloy arrangement. Meanwhile, due to the good cooling effect of this application, it can suppress the crystallization of amorphous alloys, such as preventing magnesium alloys from forming crystalline structures, promoting the stable formation of products, and also improving the quality of amorphous alloys.

[0033] Please refer to Figure 3 In some embodiments, the driving device 180 includes an electric driver 181 and a synchronous belt 182. The output end of the electric driver 181 is connected to the synchronous belt 182, and the synchronous belt 182 is connected to the quenching roller 110. For example, the synchronous belt 182 may be a common conveyor belt, and the electric driver 181 may be a motor. A perforation is made at the joint 130 to allow the synchronous belt 182 to pass through. One end of the synchronous belt 182 is connected to the output end of the motor, and the other end is fitted onto the end of the quenching roller 110. The quenching roller 110 is driven to rotate by the synchronous belt 182. Two sets of driving devices 180 can be provided, with transmission connections at both ends of the quenching roller 110 to achieve high-speed rotation. By driving the quenching roller 110 to rotate through the driving device 180, the quenching effect of the amorphous alloy is improved.

[0034] In some embodiments, the cold source circulation unit includes a circulating refrigeration device 190, a transmission pipe 140, and a recovery pipe 150. The transmission pipe 140 and the recovery pipe 150 are respectively connected to two connectors 130. The inlet and outlet of the circulating refrigeration device 190 are respectively connected to the recovery pipe 150 and the transmission pipe 140. The circulating refrigeration device 190 can be an existing device that can provide a cold source and has a circulation pipe 121. Liquid nitrogen is returned through the recovery pipe 150 and liquid nitrogen is output through the transmission pipe 140.

[0035] Please refer to Figure 4In some embodiments, the circulating refrigeration device 190 includes a cold source storage unit 191 and a circulating heat exchange assembly 192. The cold source storage unit 191 is a nitrogen-proof storage tank, which precools the refrigerant with liquid nitrogen. The inner wall of the storage tank is made of low-temperature resistant stainless steel to ensure sealing and corrosion resistance. The cold source storage unit 191 is used to store liquid nitrogen and is connected to the transmission pipeline 140 and the recovery pipeline 150. The cold source storage unit 191 is connected to the transmission pipeline 140 and is used to provide a cold source to the quench roller 110. The circulating heat exchange component 192 is connected to the recovery pipeline 150 and the cold source storage unit 191 and is used to perform heat exchange with the outside. The circulating heat exchange component 192 includes an existing multi-stage spiral coil heat exchanger, which is used to transfer the cold energy of liquid nitrogen to the refrigerant (ethylene glycol solution or brine) and deliver the cold energy to the user side through the refrigerant. For example, liquid nitrogen and refrigerant exchange heat through a plate heat exchanger. The refrigerant is delivered to the user side by a circulating pump and then returned to the storage tank to form a continuous cycle. The circulating heat exchange component 192 can realize the recovery and circulation of the cold source and realize the recycling of the coolant.

[0036] In some embodiments, the circulating refrigeration device 190 further includes a cold energy recovery unit 193, which is connected to the circulating heat exchange assembly 192 and the cold source storage unit 191, respectively, for reinjecting the vaporized cold source into the cold source storage unit 191. The cold energy recovery unit 193 uses an existing heating device and a compressor connected to the heating device. The cold source enters the compressor after passing through the heating device, where the vaporized nitrogen is heated, compressed, and then reliquefied before being returned to the cold source storage unit 191, achieving a closed-loop circulation and efficient recovery of cold energy, saving more than 30% energy compared to traditional systems.

[0037] In some embodiments, the circulating refrigeration device 190 further includes a return pipe 194 and an output pipe 195. One end of the return pipe 194 is connected to and communicates with the recovery pipe 150, and the other end is connected to and communicates with the circulating heat exchange assembly 192, for returning liquid nitrogen. One end of the output pipe 195 is connected to and communicates with the cold source storage device 191, and the other end is connected to and communicates with the transmission pipe 140, for outputting liquid nitrogen. In some embodiments, the circulating refrigeration device 190 further includes a cold source pipe 196, with both ends of the cold source pipe 196 connected to and communicates with the circulating heat exchange assembly 192 and the cold source storage device 191, respectively, for returning the liquid nitrogen, which is in a liquid state after passing through the circulating heat exchange assembly 192, to the cold source storage device 191.

[0038] In some embodiments, the circulating refrigeration device 190 further includes a pressure balancing element 197 disposed on the circulating heat exchange assembly 192 for balancing the internal and external pressures of the circulating heat exchange assembly 192. If the pressure balancing element 197 is a pressure relief valve, it can maintain the pressure within the circulating heat exchange assembly 192 within a certain range.

[0039] In some embodiments, the quenching apparatus 100 for amorphous alloy preparation further includes a pumping device 160, such as a cryogenic pump or a fluid pump, which is located in at least one of the transmission pipe 140 and the recovery pipe 150. Through the pumping device 160, the circulation of the cold source in the quenching roller 110 has a jetting effect, further improving cooling efficiency and achieving rapid cooling of the amorphous alloy. The pumping device 160 can be installed in both the transmission pipe 140 and the recovery pipe 150. Through the pumping device 160, the cooled liquid nitrogen is transported from the transmission pipe 140 into the quenching roller 110, while simultaneously circulating the liquid nitrogen from the quenching roller 110 into the recovery pipe 150, thus achieving liquid nitrogen circulation.

[0040] In some embodiments, the quenching device 100 for amorphous alloy preparation further includes a heat insulation sleeve 170, which is sleeved onto the outside of the spiral tube 120. The heat insulation sleeve 170 is used to insulate against heat from the external environment. The heat insulation sleeve 170 is made of iron and may also be covered with a layer of asbestos to ensure that the quenching space does not exchange heat with the external environment, thereby improving the yield of amorphous magnesium alloy strip spinning. In some embodiments, the heat insulation sleeve 170 has inlet and outlet holes corresponding to the nozzle 123, through which the raw material of amorphous alloy is injected. The spiral tube 120 adopts a spiral design to increase the quenching area. It is made of chromium zirconium copper material, so that the liquid nitrogen flowing through the channel can quickly reduce the ambient temperature inside the quenching space to a minimum. In some embodiments, the transmission pipe 140 and the recovery pipe 150 are connected to the heat insulation sleeve 170 and the spiral tube 120 respectively by flanges and sealed with sealing rings, such as leak-proof rubber rings.

[0041] In some embodiments, the circulating cooling device 190 further includes a housing 198, which covers the outer periphery of the circulating cooling device 190, and a driving device 180 is mounted on the outside of the housing 198. The housing 198 is cuboid and hollow inside, and the circulating cooling device 190 is placed inside the housing 198. Through holes are opened on both sides of the housing 198, and the transmission pipe 140 and the recovery pipe 150 are connected to the output pipe 195 and the return pipe 194 through the through holes on both sides, respectively. In addition, the electric driver 181 is fixed to the top of the housing 198 by screws.

[0042] The principles of this application will be explained below using liquid nitrogen as an example:

[0043] Liquid nitrogen transfer: The pumping device 160 serves as the pipeline part of the transfer pipeline 140 and the recovery pipeline 150. It draws liquid nitrogen from the cold source storage device 191 to the transfer pipeline 140, and after passing through the quench roller 110, it returns the liquid nitrogen to the circulating heat exchange component 192 through the pumping device 160 in the recovery pipeline 150.

[0044] Liquid nitrogen preparation and storage: After compression and purification, liquid nitrogen is liquefied into liquid nitrogen through multi-stage expansion refrigeration and stored in a nitrogen-proof storage tank. The pre-cooled liquid nitrogen is then transported to the output pipe 195.

[0045] Cold energy distribution and use: Liquid nitrogen is transported to the heat exchanger via a cryogenic pump, where it exchanges heat with the refrigerant. The vaporized nitrogen then enters the heating device and compressor in sequence, and after being reliquefied, it returns to the cold source storage unit 191.

[0046] Cold energy recovery and circulation: Liquid nitrogen exchanges heat with chilled water in a plate heat exchanger, transferring the cold energy to the user. The recovered liquid nitrogen returns to the cold source storage unit 191, where it exchanges heat again with newly input liquid nitrogen to continuously utilize the cold energy. Unused liquid nitrogen will be re-entered for circulating cooling through the circulation pipe 121.
