In this embodiment, a specific embodiment of a spray strip coiling integrated machine for amorphous strips is provided, which aims to effectively prevent local supercooling or overheating phenomena by optimizing a cooling structure and air flow management, thereby remarkably reducing the strip breakage risk in amorphous strip production and improving the stability and product quality of continuous production. The melting furnace heats and melts the materials, then the materials are poured into the spray head 3, the solution is uniformly sprayed on the cooling forming roller 2 through the spray openings 301 of the spray head 3, the spray openings 301 are designed to be adjustable, the spray angle and the spray width are adjusted according to production requirements, and the uniformity and the thickness control of the strip are optimized. The cooling cover 4 is made of a lightweight heat-resistant material and covers the molding area 201, so as to form a cooling space covering the molding area 201. The cooling cover 4 is internally provided with a precise air flow guiding structure comprising a first air outlet 401 and a first air suction inlet 402. The first air outlet 401 is located at the top of the cooling hood 4 and blows temperature-regulated air or inert gas through an air inlet to the molding zone 201 to assist in cooling and equalize the surface temperature. The first air suction openings 402 are located at two sides of the cooling forming roller 2, and form stable air circulation through a negative pressure suction mode, so that cooling air is ensured to be effectively discharged after uniformly flowing through the forming area 201, the temperature in the cooling space is uniform, and local overheating is avoided. The temperature uniformity in the whole production process is ensured, and the phenomenon of belt breakage is effectively avoided.
Further, the cooling cover 4 comprises a first arc-shaped air duct 403 arranged on the frame 1 and covered above the forming area 201, and the first air outlet 401 is positioned on the first arc-shaped air duct 403 and faces the forming area 201; the second arc-shaped air channels 404 are arranged at two sides of the first arc-shaped air channels 403, the first air suction ports 402 are positioned on the second arc-shaped air channels 404, and the first air suction ports 402 face two sides of the forming area 201.
The present embodiment focuses on optimizing the cooling jacket 4 to further improve cooling efficiency and temperature uniformity, reducing local supercooling or overheating phenomena, and thus reducing the risk of breakage in amorphous ribbon production. The main body of the cooling jacket 4 is a first arcuate air duct 403 made of a material that is resistant to high temperatures and has a low thermal conductivity, extending along an upper curve of the forming zone 201. The first air outlet 401 is formed at the bottom of the first arc-shaped air duct 403, and ensures that the cooling air flow uniformly covers the molding area 201 at the optimal speed and distribution through the angle and the opening size which are precisely calculated, so that heat is effectively taken away, and rapid and uniform cooling is promoted. The temperature adjusting unit can be arranged in the air duct, and the temperature of the air outlet air flow can be adjusted according to actual production conditions. In order to further enhance the cooling effect and maintain the temperature uniformity, the second arc-shaped air channels 404 are additionally arranged at two sides of the first arc-shaped air channel 403 to form a three-dimensional cooling space surrounding the forming area 201, and the cross section of the cooling space is in a U shape and covers the forming area 201. The first air suction port 402 is arranged on the second arc-shaped air duct 404 and faces to two sides of the forming area 201, and the negative pressure principle is utilized to accelerate the discharge of hot air around the forming area 201, so that the rapid circulation of new and old air flows is promoted, and the overheating phenomenon of a local area is effectively prevented.
Further, the first air outlet 401 faces the direction of material conveying, and the first arc-shaped air duct 403, the second arc-shaped air duct 404 and the cooling forming roller 2 enclose a second air outlet 405, and the second air outlet 405 faces the discharge end 203 along the tangential direction of the cooling forming roller 2.
In this embodiment, the direction of the cooling air flow is further designed, and the direction of the first air outlet 401 and the second air outlet 405 is adjusted, so that the consistency of the cooling efficiency and the material conveying direction is further optimized. The first air outlet 401 is directed towards the forming zone 201 and the air flow direction is in line with the material conveying direction, i.e. in the direction of rotation of the cooling forming roller 2. The design is beneficial to the air flow to smoothly follow and wrap the newly formed amorphous strip, so that the cooling process is effectively accelerated, the temperature of the cooling space is balanced, and the stress generated by uneven cooling in the material is reduced. The first arc-shaped air duct 403, the second arc-shaped air duct 404 and the cooling forming roller 2 jointly enclose a second air outlet 405. The second air outlet 405 is directed toward the discharge end 203 in a tangential direction of the cooling forming roller 2, and forms an auxiliary air flow path. This design not only helps to accelerate the circulation of the cooling gas, but also ensures an efficient evacuation of the hot gas flow from the sides and bottom of the forming zone 201, avoiding accumulation of hot gas near the forming zone 201, reducing localized overheating phenomena, and thus further reducing the risk of belt breakage. The first air outlet 401 and the second air outlet 405 cooperate to form a three-dimensional air circulation system. The first air outlet 401 directly acts on the surface of the material to quickly take away heat; the second air outlet 405 is guided by the air flow in the tangential direction, so that the heat exchange of the surrounding environment of the whole forming area 201 is promoted, and the high efficiency and uniformity of the cooling process are ensured. Simultaneously, the second air outlet 405 faces the discharging end 203, so that the material can be guided, the material can be further attached to the cooling forming roller 2 until the discharging end 203, and the material is given auxiliary discharging force due to the wind direction.
Further, the device further comprises a first scraper 501, wherein one end of the first scraper 501 is arranged on the frame 1 in an angle adjustable manner, the other end of the first scraper is abutted against the discharging end 203, the first scraper 501 is provided with a third air outlet 502, the third air outlet 502 faces the discharging end 203 along the surface of the first scraper 501, and the air outlet direction is opposite to the material conveying direction; the first guiding air duct 503 is disposed on the first scraper 501, and swings with the first scraper 501, and the third air outlet 502 is communicated with the first guiding air duct 503.
The embodiment further optimizes the cooling and forming process of the amorphous strip, reduces material adhesion, improves surface quality, and ensures the fluency and high efficiency of the continuous production process. The first doctor blade 501 is made of a high-hardness, wear-resistant material, and is fastened at one end to the frame 1 and is articulated by a flexible joint allowing angular adjustment in order to adjust the degree of adhesion of the doctor blade to the discharge end 203 of the cooling forming roller 2 according to different production conditions and strip thickness. Such a design ensures both a gentle stripping of the as-formed amorphous ribbon and prevents possible material build-up or adhesion, reducing subsequent processing steps.
