Description

Technical Field

[0001] The invention relates to the technical field of strip material processing, in particular to a continuous production system of nanocrystalline soft magnetic strip materials. Background Art

[0002] The preparation principle of the strip making machine is that the high-temperature liquid is sprayed on the high-speed rotating cooling roller through the nozzle, and the cooling effect of the cooling roller is used to quickly cool the surface cooled thin layer and throw it out to form a strip. At present, the most commonly used cooling method is water cooling. For example, a Chinese patent discloses a nanocrystalline soft magnetic alloy ultra-wide and ultra-thin strip preparation device (CN209697999U), which uses water cooling plus fins for cooling. The high-speed rotating copper sleeve is cooled after passing through the water tank. However, during the high-speed rotation process, under the influence of the rotation force, the liquid will be quickly thrown out along the tangent direction of the copper roller. On the one hand, the water increases the rotation resistance and causes the drive energy waste. On the other hand, the generated sputtering water will also affect the strip body, causing water stains to adhere to the strip body. In addition, how to ensure that the water on the surface of the copper roller will not affect the product cooling reaction during the cooling process with the high-temperature liquid.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 7: In this embodiment, it includes a nozzle assembly 1, an external cooling assembly 2, and an internal cooling assembly 3. The external cooling assembly 2 includes an external air duct outlet pipe 22 and an air inlet outer pipe 23. The air inlet outer pipe 23 and the external air duct outlet pipe 22 are connected through a cooling roller 24. The two ends of the cooling roller 24 are rotatably connected to the air inlet outer pipe 23 and the external air duct outlet pipe 22 respectively. The last section cooling arc wind plate 21 is fixed to the end of the external air duct outlet pipe 22. The air outlet of the last section cooling arc wind plate 21 is connected to the external air duct outlet pipe 22. The liquid flowing out of the nozzle assembly 1 is located directly above the cooling roller 24. The internal cooling assembly 3 includes an internal air duct outlet pipe 32 and an air inlet inner pipe 33. The air inlet inner pipe 33 is located inside the air inlet outer pipe 23 and A first channel interlayer is formed, and the inner air duct outlet pipe 32 vertically passes through the bent end of the outer air duct outlet pipe 22, and the outer air duct outlet pipe 22 and the inner air duct outlet pipe 32 form a third channel interlayer, the outer air duct outlet pipe 22 and the inner air duct outlet pipe 32 are rotatably connected, the inner air duct outlet pipe 32 is connected to the air inlet inner pipe 33 through the contoured inner cover 34, and the contoured inner cover 34 and the cooling roller 24 form a second channel interlayer, and the above three channel interlayers are connected to the outer air duct outlet pipe 22, and the end of the inner air duct outlet pipe 32 is fixedly connected with a middle-section separation cooling arc wind plate 31, and the middle-section separation cooling arc wind plate 31 is located below the contoured inner cover 34, and the air outlet of the middle-section separation cooling arc wind plate 31 is connected to the air inlet inner pipe 33.

[0024] In this embodiment, the melting module melts the material and then transports it to the nozzle assembly 1, and the liquid material is linearly sprayed on the surface of the cooling roller 24 through the nozzle assembly 1. The air inlet cooling module blows in cooling gas, such as air cooled by the refrigeration mechanism, see Figure 6 Since the axes of the air inlet outer pipe 23 and the air inlet inner pipe 33 are in a collinear line, when the high-speed cooling gas passes through the air inlet outer pipe 23, the airflow flows through the first channel interlayer and the inside of the air inlet inner pipe 33, and the gas located in the first channel interlayer quickly passes through the second channel interlayer between the cooling roller 24 and the contoured inner cover 34. After the gas passes through the inner wall bottom surface of the cooling circumferential surface 241 and the outer wall surface of the contoured inner cover 34 for rapid heat exchange, it is discharged to the outer air duct outlet pipe 22 through the third channel interlayer, and acts on the last cooling arc wind plate 21 through the outer air duct outlet pipe 22. The nozzle on the surface of the last cooling arc wind plate 21 is affected by the gas of the outer air duct outlet pipe 22 and sprays the gas on the surface of the cooling circumferential surface 241, cooling the outer wall of the cooling circumferential surface 241. The cooled part quickly rotates to the position in contact with the liquid, ensuring that the temperature of the cooling circumferential surface 241 in contact with the liquid is minimized, thereby ensuring the cooling effect of the belt body.

[0025] In this embodiment, please refer to Figure 6 The other part of the gas enters the interior of the contoured inner cover 34 through the air inlet inner pipe 33, passes through the contoured inner cover 34 to the inner air duct outlet pipe 32, and is transported to the middle separation cooling arc air plate 31 through the inner air duct outlet pipe 32. Figure 7 The nozzle of the middle-section separation cooling arc wind plate 31 sprays gas obliquely upward in the tangent direction of the cooling roller 24 against the rotation direction of the cooling roller 24. A part of the gas acts on the surface of the cooling circumferential surface 241. Affected by the arc-shaped guidance of the middle-section separation cooling arc wind plate 31, the wind blows toward the belt body, promoting the separation of the belt body and the cooling circumferential surface 241, and cooling the cooling circumferential surface 241 at the same time.

[0026] In the present embodiment, the structure of the cooling roller 24 is simplified. The cooling roller 24 is both a cooling surface and a gas delivery pipeline. Through the secondary diversion of the gas, it is firstly ensured that the gas can move quickly against the circumferential surface of the cooling roller 24 for heat exchange, and after the gas is discharged, the surface separated from the processing liquid is subjected to secondary cooling to promote belt separation and tertiary cooling to remove impurities, thereby ensuring that the temperature of the cooling roller 24 is still within a safe range during long-term continuous processing, and simplifying the process steps, and the triple cooling operation can be completed by a separate air cooling mechanism.

[0027] In this embodiment, a cooling circumferential surface 241 is provided in the middle of the cooling roller 24 , and the cooling circumferential surface 241 is connected and transitioned with the pipe mouth of the cooling roller 24 through a continuous tangent arc surface, and the pipe mouth diameter of the cooling roller 24 is smaller than the diameter of the cooling circumferential surface 241 .

[0028] In this embodiment: first, the cooling roller 24 is disc-shaped, and the air inlet end can only be located at the center of the circle. Therefore, in order to reduce wind energy loss, tangent arc surfaces are set at both ends of the cooling roller 24 to transition with the cooling circumferential surface 241, and the setting of the contoured inner cover 34 is coordinated to form a wind flow channel between the cooling roller 24 and the contoured inner cover 34, and the tangent surface can reduce wind energy loss, so that the cooling gas can move along the second channel interlayer, thereby ensuring that the wind is in contact with the cooling circumferential surface 241 for heat exchange, ensuring the high efficiency of heat exchange on the inner wall of the cooling circumferential surface 241.

[0029] In this embodiment: a bracket is provided below the outer cooling component 2 and the inner cooling component 3, and the bracket is rotatably connected to the two ends of the cooling roller 24 through a rotating bearing. Gears are provided at both ends of the cooling roller 24, and a driving chassis is provided below the bracket. The driving chassis extends to the gear of the cooling roller 24 through the driving component 4 to drive the cooling roller 24 to be rotatably connected.

[0030] In this embodiment: the bracket supports the cooling roller 24, the driving component 4 is driven by a belt, the belt is connected to the gear, and the transmission box below is connected to the driving motor, so that the belt can drive the cooling roller 24 to rotate at a high speed, and the cooling roller 24 and the air inlet outer pipe 23 and the outer air duct outlet pipe 22 are closed and rotated through a dynamic sealing structure to ensure air tightness.

[0031] In this embodiment: a locking plate 5 is fixedly connected to the bracket, and two track grooves are provided on the locking plate 5. An outer adjusting rod 25 is fixedly connected to the outer air duct outlet pipe 22, and an inner adjusting rod 35 is fixedly connected to the inner air duct outlet pipe 32. The outer adjusting rod 25 and the inner adjusting rod 35 rotate in the track groove of the locking plate 5 and are locked with the locking plate 5 through a fixer.

[0032] In this embodiment: Please refer to Figure 5 According to the requirements, the user can adjust the rotation direction of the outer air duct outlet pipe 22 and the inner air duct outlet pipe 32, so as to adjust the corresponding positions of the end cooling arc wind plate 21 and the middle separation cooling arc wind plate 31 at the cooling roller 24. The purpose of adjusting the middle separation cooling arc wind plate 31 is to control the position of blowing on the belt body to promote separation. The outer adjustment rod 25 and the inner adjustment rod 35 are fixedly connected to the outer air duct outlet pipe 22 and the inner air duct outlet pipe 32 respectively, and the locking plate 5 is fixed to the bracket, so the outer adjustment rod 25 and the inner adjustment rod 35 can rotate in the track groove, and are fixed to the locking plate 5 through the locking mechanism such as the hand screws and nuts on the top of the outer adjustment rod 25 and the inner adjustment rod 35.

[0033] In this embodiment: the bottom of the last cooling arc wind plate 21 is fixedly connected with an outer row plate 211, the last cooling arc wind plate 21 is concentric with the cooling roller 24, and the outer row plate 211 is tangent to the cooling roller 24. In order to prevent impurities from adhering to the surface of the cooling circumferential surface 241, the gas blown by the last cooling arc wind plate 21 acts on the surface of the cooling circumferential surface 241, so that the surface impurities fall to the outer row plate 211 and are discharged outward, thereby ensuring the processing quality of the previous strip body.

[0034] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
