Description

Technical Field

[0001] The utility model relates to the technical field of baffle components, in particular to a baffle component for a continuous casting machine. Background Art

[0002] Continuous casting is the intermediate link between steelmaking and steel rolling. Molten steel flows continuously into the tundish, and after being mixed and divided in the tundish, it is injected into the crystallizer for cooling and solidification to obtain infinitely long ingots. After the ingots are cut to a fixed length by a flame cutting machine, they are transported through the ingot discharge device. The ingot discharge device includes a conveying roller and a lifting baffle set between the conveying rollers. The lifting baffle is used to block and position the ingot so that the lateral steel moving car can push the ingot on the conveying roller to the cooling bed, where it is cooled and waits for the next processing.

[0003] A baffle assembly for a continuous casting machine in the prior art will generate a large impact force on the baffle body when the ingot collides with the baffle body, and the impact force is transmitted to the first telescopic rod. After a long period of use, the first telescopic rod will bend and deform, resulting in the baffle body being unable to work normally, and the practicality is poor. In addition, the slag generated by the ingot during collision or transportation is not collected and processed, resulting in the slag being randomly scattered at the bottom of the device and emitting high temperature, and the practicality is poor.

[0028] The effect achieved by the entire embodiment 2 is that when the baffle body 5 is hit, it will first hit the block 803, and the block 803 buffers the impact force on the baffle body 5 through the buffering and shock absorption of the first spring 802 and the damper 804. In addition, through the arrangement of the stabilizing column 7 and the stabilizing plate 6, the baffle body 5 can be further supported and stabilized to avoid the bending of the first telescopic rod 4, and the operation of the second telescopic rod 27 can drive the guide plate 28 to descend, thereby blocking the two sides of the impacted embryo to avoid the tilting phenomenon, which is more practical. When the embryo debris is collected and cooled At the same time, the operation of the motor 20 can drive the fan 21 to rotate, so that the hot air generated by the cooling of the debris is quickly discharged from the air outlet chamber 19. The position of the collection box 13 is limited by the setting of the card column 1501 to prevent the collection box 13 from accidentally slipping out.

[0029] Working principle: When the device is used, the embryo is transported by multiple conveying rollers 2, and the operation of the two first telescopic rods 4 drives the baffle body 5 to move up to block the embryo. The blocked embryo is pushed by an external pushing device to fall onto the external cooling bed for subsequent processing. When the baffle body 5 is hit, it will first hit the block 803, and the block 803 buffers the impact force on the baffle body 5 through the buffering and shock absorption of the first spring 802 and the damper 804. The operation of the second telescopic rod 27 can drive the guide plate 28 to descend, thereby blocking both sides of the impacted embryo to prevent it from coming out. The phenomenon of tilting occurs, and the debris dropped from the cast embryo will pass through the spacing between every two conveying rollers 2 and the guidance of the connecting cavity 11, and fall into the collecting box 13 sliding in the chassis 12. Because water has been poured into the collecting box 13 in advance, the debris will be quickly cooled down and collected. While the debris of the cast embryo is collected and cooled, the operation of the motor 20 can drive the fan 21 to rotate, so that the hot air generated by the cooling of the debris is quickly discharged from the air outlet cavity 19. When it is necessary to remove the collecting box 13, it is only necessary to use the pulling plate 1502 to drive the clamping column 1501 to disengage from the clamping slot 18. At this time, the collecting box 13 can be directly returned, and the debris inside it can be cleaned and the water source can be replaced.
