[0002] At present, the common cooling roller structure is composed of three parts: the main shaft, the roller core and the cooling copper sleeve. The cooling water enters from one end of the hollow main shaft, enters the roller core through the water outlet on the main shaft. The roller core is a cavity structure, and then flows out from the water outlet on the outer surface of the roller core and enters the copper sleeve waterway to achieve the cooling effect. The cooling water flows out from the copper sleeve, flows into the other side of the roller core, and then enters the pipe back to the cooling water pool through the return port at the other end of the main shaft, forming a cooling water cycle.

[0003] However, this type of cooling roller has the following problems: complex structure, high cost, poor cooling effect, unreasonable water channel structure, high water pressure requirement and uneven distribution of each water channel.

[0004] To this end, a cooling roller device for the production of amorphous nanocrystalline strips was invented based on the problem that needed to be solved. The entire device was divided into several sectors, and a separate water outlet and water inlet were set inside each sector. The cooling water then evenly entered the equally divided annular water channel inside the copper sleeve through a unique nozzle, and the centrifugal force of the rotation of the cooling roller was used to accelerate the circulation of the cooling water.

[0024] like Figure 1-6 As shown, a cooling roller device for the production of amorphous nanocrystalline strips includes a main shaft, water inlet cavities and water outlet cavities are arranged inside the two ends of the main shaft 10, the outer ring of the main shaft 10 is sleeved with an inner sleeve 9, the inner sleeve 9 is provided with a water inlet hole and a water outlet hole and is fixed to the outer ring of the main shaft 10 on both sides through a first shaft flange 6 and a second shaft flange 7, the outer ring of the inner sleeve 9 is sleeved with a diverter sleeve 8, the outer ring of the diverter sleeve 8 is sleeved with a water tray ring composed of a first water tray 4 and a second water tray 5, a plurality of water channels are arranged inside the water tray ring, the outer ring of the water tray ring is sleeved with a cooling roller copper sleeve 1, the water channels are clamped with a plurality of nozzles 11, and the upper and lower surfaces of the nozzles 11 are respectively connected to the inner ring of the cooling roller copper sleeve 1 and the outer ring of the water tray ring. Among them, the strip is located on the cooling roller, and cooling water is injected from one side while the cooling roller rotates. During the rotation process, the cooling water enters the water pan through the water inlet hole of the main shaft 10, the water inlet hole of the inner sleeve 9 and the water inlet hole of the diverter sleeve 8, and then is sprayed from the water inlet hole of the water pan through the nozzle 11 to the water tank 12 of the inner ring of the copper sleeve 1 of the cooling roller. Since the number of spray holes 13 of the nozzle 11 is the same as that of the water tank 12, the amount of cooling water in the water tank 12 is the same. The cooling water injected into the water tank 12 flows through the water tank 12 and flows out from the spray hole 13 of the nozzle 11 opposite to the other end, enters the water outlet hole of the water pan, the water outlet hole of the diverter sleeve 8, the water outlet hole of the inner sleeve 9 and the water outlet hole of the main shaft 10, and flows out from the cavity at the other end inside the main shaft. During the rotation process, the circulation of cooling water is accelerated by centrifugal force to improve the cooling effect.

[0025] like Figure 1 and Figure 2As shown, the main shaft 10, the inner sleeve 9 and the diverter sleeve 8 are all divided into a plurality of identical sectors, and the sectors are all provided with independent water inlet holes and water outlet holes, and the water inlet holes and water outlet holes of the main shaft 10, the inner sleeve 9 and the diverter sleeve 8 are connected.

[0029] like Figure 3 and Figure 4 As shown, the inner ring of the cooling roller copper sleeve 1 is provided with a plurality of fan-shaped cavities, and the fan-shaped cavities are respectively provided with a plurality of water grooves 12. During the rotation process, the cooling water is evenly distributed through the plurality of water grooves 12 in the fan-shaped cavities and the cooling water with heat is quickly replaced, so that the strip can be quickly cooled.

[0030] like Figure 3 As shown, one end of the water trough 12 is connected to the spray hole 13 opposite to the water outlet channel, and the other end is connected to the spray hole 13 of the adjacent nozzle 11 opposite to the water inlet channel. The nozzle 11 is fixed between two adjacent sectors, and during the rotary cooling process, the two ends of the water trough 12 are respectively opposite to the two rows of spray holes 13 of the nozzle 11, and the cooling water in the water trough 12 is recovered through the nozzle 11.

[0031] like Figure 1 and Figure 2 As shown, the first outer flange 2 and the second outer flange 3 are connected to both sides of the connection between the inner ring of the cooling roller copper sleeve 1 and the outer ring of the water pan ring. The cooling roller copper sleeve 1 is fixed by the flange, and it will not fall off during the rotation process. When maintenance and replacement are required in the later stage, only the flange needs to be removed, which is convenient and quick.
