Description

빌레트의 이동속도 감속장치{Device for reduction of the speed of billet in the continuous casting process}Device for reduction of the speed of billet in the continuous casting process}

본 발명은 통상적인 연속주조 공정에 있어서 빌레트의 이동속도를 감속시켜 주는 장치에 관한 것으로서, 시소의 원리를 이용한 장치로서 롤의 회전속도를 감속함으로써 빌레트의 이동속도를 감속시키는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for reducing the moving speed of a billet in a conventional continuous casting process. The present invention relates to a device for reducing the moving speed of a billet by reducing the rotational speed of a roll as a device using the principle of seesaw.

도 1a ∼ 도 1c는 연주공정에서의 종래의 빌레트 이송장치의 개념도이다. 연속주조공정에서 인발되는 빌레트(1)는 일정한 길이(8000mm, 10100mm)로 절단된 후, 모터(2)에 체인(3)으로 연결된 구동롤(4)의 회전력에 의하여 이동하여 와서 스토퍼(5)에서 멈춘 후 도면의 안쪽방향으로 밀려서 다음 공정으로 이송된다.1A to 1C are conceptual views of a conventional billet feeder in a playing step. The billet (1) drawn out in the continuous casting process is cut to a certain length (8000mm, 10100mm), and then moved by the rotational force of the driving roll (4) connected by the chain (3) to the motor (2) and the stopper (5) After stopping at, it is pushed inward of the drawing and transferred to the next process.

절단된 중량(2TON)의 빌레트(1)는 롤의 회전력에 의하여 이송되는 과정에서 가속도가 증가되어 점점 속도가 빨라지게 되며 인발공정에서의 빌레트의 속도를 제어할 아무런 장치가 없으므로 말단부에 설치된 스토퍼(5)에 충돌된다(도 1b). 이 때 스토퍼(5)에 가해지는 충격은 대단하여 충돌한 빌레트(1)는 뒤로 밀리게 되어 구동롤(4)이 역회전하게 된다(도 1c).The billet (1) of the cut weight (2TON) is accelerated in the process of being conveyed by the rotational force of the roll and becomes faster, and there is no device to control the billet's speed in the drawing process. 5) (FIG. 1B). At this time, the impact applied to the stopper 5 is so great that the collided billet 1 is pushed back so that the driving roll 4 is reversely rotated (Fig. 1C).

구동롤(4)의 역회전시 모터(2)에도 직접적인 영향을 미쳐 모터(2)의 트러블의 직접적인 원인으로 작용하고, 설비파손에 의한 조업중단으로 이어지고 막대한 생산손실이 발생하고 있다.In the reverse rotation of the driving roll 4 also directly affects the motor 2, which acts as a direct cause of the trouble of the motor 2, leading to an operation interruption due to equipment damage, and enormous production loss.

본 발명은 전술한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서,절단된 빌레트의 인발과정에서 구동롤의 회전력을 줄여서 인발속도를 제어함으로써 빌레트가 정지할 때 설비에 미치는 충격을 최소화하고, 빌레트가 정지할 때에 뒤로 밀려서 모터에 미치는 부하를 감소시켜 설비고장을 예방할 수 있는 빌레트 이동속도의 감속장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, by reducing the rotational force of the driving roll in the drawing process of the cut billet to minimize the impact on the equipment when the billet is stopped, by controlling the drawing speed, the billet is It is an object of the present invention to provide a deceleration device of a billet moving speed that can be pushed backward when stopping to reduce the load on the motor to prevent equipment failure.

도 6에서 빌레트(1)가 화살표 방향으로 이동하여 감속장치에 도달하면 감속장치의 완충부(10)가 구동롤(4)보다 위로 튀어나와 있으므로 완충부(10)가 빌레트(1)의 무게에 눌려져 밑으로 내려가게 되고, 지지대(22)의 반대쪽에 있는 감속부(30)가 위로 올라가 구동롤(4)에 접촉함으로써 구동롤(4)의 회전속도를 떨어뜨리게 된다.In FIG. 6, when the billet 1 moves in the direction of the arrow to reach the deceleration device, the buffer part 10 of the reduction device protrudes above the driving roll 4, and thus the buffer part 10 is applied to the weight of the billet 1. It is pressed down to the bottom, and the speed reduction portion 30 on the opposite side of the support 22 rises up to contact the driving roll 4, thereby lowering the rotational speed of the driving roll 4.

도 7과 같이 빌레트(1)가 본 감속장치를 지나가게 되면, 완충부(10)와 감속부(30)는 무게 중심에 의하여 다시 원위치로 돌아오게 되며, 감속장치에 의하여 이미 감속된 빌레트(1)는 스토퍼(40)의 경사진 밑면에 얹혀지게 되고 스토퍼(40)의 수직면과의 직접적인 충돌을 피하며 가볍게 정지할 수 있게 된다.When the billet 1 passes through the speed reducer as shown in FIG. 7, the shock absorber 10 and the speed reducer 30 are returned to their original positions by the center of gravity. ) Is placed on the inclined bottom surface of the stopper 40 and can be stopped lightly avoiding a direct collision with the vertical surface of the stopper 40.

본 발명의 감속장치는 빌레트의 이동속도를 제어하여 빌레트가 정지할 때에 충격 또는 역회전에 의한 설비의 고장을 예방함으로써 이송설비에 미치는 악영향을 최소화하여 정비회수 감소 및 설비효율을 증대시키고, 정확한 정지작업이 가능하게 하여 작업능률을 제고시키고 궁극적으로 설비의 수명연장으로 원가절감 및 생산성 향상에 크게 기여한다.Reduction device of the present invention by controlling the moving speed of the billet to prevent the failure of the equipment due to the impact or reverse rotation when the billet is stopped to minimize the adverse effect on the transfer equipment to reduce the number of repairs and increase the efficiency of the equipment, and accurate stop It enables work to improve work efficiency and ultimately contributes to cost reduction and productivity improvement by extending equipment life.
