It is usually a combination of steel casting equipment, continuous casting machine main equipment, cutting equipment, ingot guide device and conveying equipment.

[0003] During the production and processing of the continuous casting machine, the produced ingot needs to be crystallized and secondary cooled to ensure that the ingot can solidify in a relatively short time. When the ingot is secondary cooled, multiple atomizing nozzles are mostly used to cover the surface of the ingot with water mist to ensure that the ingot can solidify quickly. In actual use, since the atomizing nozzles are placed in a concentrated position and the position of the atomizing nozzles is relatively fixed when in use, the water mist edges of adjacent atomizing nozzles overlap, resulting in excessively fast cooling of the ingot at the overlapping water mist edges, causing uneven cooling. Therefore, a cooling device for a fan-shaped section of a continuous casting machine is proposed. Utility Model Content

[0031] like Figures 1 to 6 As shown, a cooling device for a fan-shaped section of a continuous casting machine comprises: a fixed frame 1, wherein a connecting rod is arranged inside the fixed frame 1, and the connecting rod is multiple; a guide section 2, which is arranged inside the fixed frame 1 and is used for guiding a plate; a cooling component 3, which is arranged outside the guide section 2 and is used for cooling the plate; a moving mechanism, which is arranged inside the cooling component 3 and is used for adjusting the cooling position of the cooling component 3, specifically, when in use, the continuously cast billet is guided by the guide section 2 to ensure the accuracy of the billet movement direction after casting, and while guiding the billet, the billet is evenly cooled by spraying water through the cooling component 3 in cooperation with the moving mechanism, so that the billet can harden quickly and evenly, and cracks on the billet surface caused by uneven cooling are avoided.

[0032] like Figures 1 to 6 As shown, the guide section 2 includes an arc plate 201, and there are multiple arc plates 201, and the arc plates 201 are connected to the connecting rods. Rotating rollers 202 are arranged between the arc plates 201, and there are multiple rotating rollers 202, and the rotating rollers 202 rotate relative to the arc plates 201. Support shafts 203 are arranged inside the rotating rollers 202, and the support shafts 203 rotate synchronously with the rotating rollers 202. Specifically, a crystallizer is also arranged on the top of the fixed frame 1 to ensure that crystallization can be achieved inside the ingot. After crystallization, the ingot is guided with the cooperation of the arc plate 201 and the rotating rollers 202, so as to facilitate cutting of the long strip ingot. A motor is arranged at the other end of the support shaft 203, and the support shaft 203 is driven by the motor to rotate. Since the rotating rollers 202 are fixedly connected to the support shafts 203, the rotating rollers 202 roll relative to the ingot when guiding the ingot, thereby reducing the friction during the guiding process and ensuring the stability of the ingot when guiding the ingot.

[0033] like Figures 1 to 6As shown, the cooling component 3 includes a fixed frame 301 and a cooling member 306, the fixed frame 301 is U-shaped, there are multiple fixed frames 301, both ends of the fixed frame 301 are connected to the arc plate 201, a sliding groove 302 is provided inside the fixed frame 301, the directions in which both ends of the sliding groove 302 extend are parallel to the axis of the rotating roller 202, there are multiple sliding grooves 302, a connecting groove 303 is provided inside the fixed frame 301, the connecting groove 303 corresponds to the sliding groove 302, and the sliding groove 302 is connected to the connecting groove 303, a connecting block 304 is provided on the outside of the cooling member 306, and the connecting block 304 slides inside the connecting groove 303, and a water inlet pipe 305 is provided on the outside of the cooling member 306. Specifically, the fixed frame 301 is divided into It is arranged on the upper and lower sides of the arc plate 201, so that when the rotating roller 202 guides the ingot, the temperature of the ingot can be reduced through the cooperation of the fixed frame 301 and the cooling member 306, thereby accelerating the solidification speed of the ingot. A plurality of atomizing nozzles are arranged on the outside of the cooling member 306 to ensure that the water mist sprayed during use can be evenly sprayed on the surface of the ingot to avoid cracks on the surface of the ingot due to uneven cooling. The cooling water enters the cooling member 306 through the water inlet pipe 305. The relative position of the water inlet pipe 305 and the fixed frame 301 can be changed by adjusting the connecting block 304, so that the cooling member 306 can be adjusted according to the shape and position of the ingot to ensure stability during cooling. The cooling member 306 is a prior art and will not be explained in detail here.

[0034] like Figures 1 to 6 As shown, the transmission component 4 includes a chain 402, a first sprocket 401 and a second sprocket 403. The second sprocket 403 is connected to the support shaft 203. There are multiple first sprockets 401, and the first sprocket 401 is meshed with the chain 402. Specifically, the second sprocket 403 is connected to one end of the support shaft 203. The first sprocket 401 drives the moving component 5 to rotate, so that the moving component 5 adjusts the position of the cooling component 306 relative to the ingot while rotating, so as to avoid the edges of the nozzle water mist overlapping each other and causing excessive cooling. When in use, since the second sprocket 403 is connected to the support shaft 203, the chain 402 drives the first sprocket 401 to rotate while the second sprocket 403 rotates, thereby providing power for the moving component 5 to move.

[0035] like Figures 1 to 6As shown, the moving assembly 5 includes a gear 501, a rotating rod 502 and a connecting sleeve 503. The rotating rod 502 is arranged inside the sliding groove 302, and the axis of the rotating rod 502 is parallel to the direction in which the two ends of the sliding groove 302 extend. There are multiple rotating rods 502, and adjacent rotating rods 502 form a group. The rotating rods 502 correspond to the sliding groove 302. The gear 501 is arranged at the end of the rotating rod 502, and the gear 501 corresponds to the rotating rod 502. The gear 501 is connected to the first sprocket 401, and the connecting sleeve 503 is sleeved on the rotating rod 5 02, the connecting sleeve 503 is provided with a through hole 504 inside, the through hole 504 is provided with a guide groove 505 inside, the guide groove 505 is provided with a guide block 506 inside, and the guide block 506 is connected to the rotating rod 502. Specifically, the rotating rods 502 on adjacent sides are meshed and connected through the gear 501, so that when the first sprocket 401 is connected to any gear 501 of each group, the meshing of the gear 501 can drive the entire group of rotating rods 502 to rotate, and the guide groove 505 is a wavy ring. The fixed position relative to the fixed frame 301 allows the connecting sleeve 503 and the connecting block 304 to reciprocate through the cooperation of the guide block 506 and the guide groove 505 during the rotation of the rotating rod 502. Since the connecting block 304 is connected to the cooling member 306, the cooling position of the cooling member 306 is continuously adjusted during the movement of the connecting block 304 to avoid local overcooling of the ingot during the cooling process. When the rotating rod 502 drives the connecting sleeve 503 to move, the multiple connecting sleeves 503 of the same group move in opposite directions. The setting of the cooling component 306 avoids cooling dead corners when the cooling component 306 moves, ensuring uniform cooling. When the first sprocket 401 drives any gear 501 to rotate, the rotating rod 502 rotates under the engagement of the gear 501. Since the guide block 506 is fixed to the rotating rod 502, the guide groove 505 cooperates with the guide block 506 to push the through hole 504, the connecting block 304 and the cooling component 306 to move back and forth in a straight line during the rotation of the rotating rod 502, thereby avoiding the occurrence of local excessive cooling during cooling.
