염산탱크내 서포트롤 분리장치{SEPERATING DEVICE FOR SUPPORT ROLL IN THE HCl TANK}Separation device for support trolley in hydrochloric acid tank {SEPERATING DEVICE FOR SUPPORT ROLL IN THE HCl TANK}

본 발명은 염산탱크내 서포트롤 분리장치에 관한 것으로, 보다 상세하게는 냉간압연전 표면이 미려한 전기강판 생산을 위해 예비소둔 및 숏 블라스트 처리된 표면을 염산으로 산세할 때 사용되는 서포트롤의 손상시 이를 신속하고 용이하게 교체, 적재하여 생산성 향상을 이루도록 한 염산탱크내 서포트롤 분리장치에 관한 것이다.The present invention relates to a support trolley separation device in a hydrochloric acid tank, and more particularly, in the case of damage to the support trolley used for pickling preannealed and shot blasted surfaces with hydrochloric acid for the production of beautiful steel sheets before cold rolling. The present invention relates to a support trolley separation device in a hydrochloric acid tank for quick and easy replacement and loading to improve productivity.

일반적으로, 전기강판이 냉간압연되기 전에 그 표면의 잔류 이물들을 제거하여 미려함을 획득하기 위하여 예비소둔 및 숏 블라스트 처리된 강판 표면에 염산을 이용하여 산세하는 공정을 거치게 된다.In general, before the cold rolled electrical steel sheet is subjected to a process of pickling with hydrochloric acid on the surface of the pre-annealed and shot blasted steel sheet in order to remove the remaining foreign matter on the surface to obtain a beauty.

이러한 산세공정은 화학적인 반응에 의한 강판 표면상의 스케일을 제거하기 위한 것으로, 예컨대 18%의 염산을 강판 표면에 반응시켜 기계적인 방법으로 제거되지 못하던 미세한 잔류 스케일들까지 깨끗하게 제거시키는 화확적인 세정 공정이며, 그 반응식은 아래와 같다.This pickling process is to remove the scale on the surface of the steel sheet by a chemical reaction. For example, 18% hydrochloric acid is reacted to the surface of the steel sheet to cleanly remove fine residual scales that could not be removed by a mechanical method. The reaction scheme is as follows.

(염산과 강판의 반응식)(Scheme of Hydrochloric Acid and Steel Plate)

FeO + 2HCl → FeCl2 + H2OFeO + 2HCl → FeCl 2 + H 2 O

또한, 전기강판중 방향성 전기강판의 경우에는 우수한 자기적 성질을 얻기 위해 비저항 증가에 가장 유효한 합금성분인 규소 성분을 3% 정도 함유시켜 철손을 낮추고 자성은 높이기도 하고 있다.In addition, in the case of the oriented electrical steel sheet of the electrical steel sheet to reduce the iron loss and increase the magnetism by containing about 3% of the silicon component which is the most effective alloy component to increase the specific resistance to obtain excellent magnetic properties.

나아가, 상기 완충실린더(470) 사이의 공간상에는 일정간격을 두고 다수의 롤가이드(480)가 설치되는데, 상기 롤가이드(480)의 일단은 구동휠(440)의 축상에 고정되고, 타단은 별도의 브라켓에 의해 지지되면서 롤러테이블(460)을 향해 상향 경사지게 설치된다.Furthermore, a plurality of roll guides 480 are installed at a predetermined interval in the space between the buffer cylinders 470, one end of the roll guide 480 is fixed on the axis of the drive wheel 440, the other end is separate While being supported by the bracket of the roller table 460 is installed upwardly inclined.

뿐만 아니라, 상기 롤가이드(480)의 최하단에는 스토퍼(482)가 돌출형성되고, 길이 중앙부에는 완충핀(484)이 구비된다.In addition, a stopper 482 protrudes from the lower end of the roll guide 480, and a buffer pin 484 is provided at a central portion thereof.

이때, 상기 스토퍼(482)는 상기 서포트롤(110)과 대응되는 곡률반경을 가지고 만곡지게 형성됨이 바람직하고, 상기 완충핀(484)은 상기 롤가이드(480)에 도시되지 않은 스프링에 의해 탄성적으로 회전유동될 수 있는 핀고정 방식으로 구비된다.At this time, the stopper 482 is preferably formed to be curved having a radius of curvature corresponding to the support trolley 110, the buffer pin 484 is elastic by a spring not shown in the roll guide 480 It is provided in a pinned manner that can be rotated flow.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

산세공정을 수행하던중 서포트롤(110)의 훼손이 발생되면 먼저, 작업자는 염산탱크(100)의 외측에서 서포트롤(110)를 1차적으로 해체한다.When the support trolley 110 is damaged during the pickling process, the worker first dismantles the support trolley 110 from the outside of the hydrochloric acid tank 100.

이어, 레일(R)을 따라 롤푸싱기(200)를 이동시켜 교체 대상 서포트롤(110)에 정위치시킨다.Subsequently, the roll pushing machine 200 is moved along the rail R to be positioned in the replacement target support 110.

이와 동시에, 롤푸싱기(200)의 대향측에는 서포트(300)를 걸어 배치하고, 그 인접측에는 적당한 간격을 두고 롤적치대(400)를 위치시킨다.At the same time, the support 300 is hanged on the opposite side of the roll pushing machine 200, and the roll stacker 400 is positioned at the adjacent side at appropriate intervals.

이렇게 하여 롤푸싱기(200), 서포트(300), 롤적치대(400)가 정위치되면 작동모터(250)를 동작시켜 피니언기어(240)를 회전시키고, 이에 따라 피니언기어(240)와 치결합된 래크기어(230)가 가이드(220)내에서 전진하게 된다.In this manner, when the roll pushing machine 200, the support 300, and the roll holder 400 are in the correct position, the operation motor 250 is operated to rotate the pinion gear 240, thereby engaging the pinion gear 240. The rack gear 230 is advanced in the guide 220.

상기 래크기어(230)의 전진에 따라 푸셔(260)가 전진되고, 이 푸셔(260)는 서포트롤(110)의 축 일단에 끼워지면서 이를 밀게 된다.The pusher 260 is advanced as the rack gear 230 moves forward, and the pusher 260 is pushed while being fitted to one end of the shaft of the support trolley 110.

따라서, 상기 서포트롤(110)은 상기 푸셔(260)에 의해 적정거리만큼 밀리면서 반대쪽으로 돌출되게 되고, 돌출된 부위는 서포트(300)의 상부롤(340)과 하부롤(330) 사이로 진입되게 된다.Therefore, the support trolley 110 protrudes to the opposite side while being pushed by the pusher 260 by an appropriate distance, so that the protruding portion enters between the upper roll 340 and the lower roll 330 of the support 300. do.

이때, 상기 상부롤(340)은 서포트모터(350)에 의해 회전되고 있으므로 하부 롤(330)과 서포트롤(110)를 맞물은 상태로 이 서포트롤(110)을 당기게 된다.At this time, since the upper roll 340 is rotated by the support motor 350, the support roll 110 is pulled in a state in which the lower roll 330 is engaged with the support roll 110.

물론, 자기 역할을 수행완료한 푸셔(260)는 어느 정도까지 움직인 후 작동모터(250)의 역회전에 의해 초기 위치로 복귀됨이 바람직하다.Of course, the pusher 260, which has completed its own role, is preferably returned to the initial position by the reverse rotation of the operating motor 250 after moving to some extent.

이렇게 하여 서포터(300)에 의해 당겨진 서포트롤(110)은 롤적치대(400)상의 롤러테이블(460)로 이동됨으로써 서포트롤(110)의 해체, 교환을 위한 분리작업은 완료되게 된다.In this way, the support trolley 110 pulled by the supporter 300 is moved to the roller table 460 on the roll holder 400 so that the separation work for disassembly and exchange of the support trolley 110 is completed.

한편, 롤러테이블(460)로 이동된 서포트롤(110)은 그대로 방치되거나 별개의 장소로 이송될 수도 있으나 다른 서포트롤들을 해체하기 위한 작업을 연속적으로 병행할 경우에는 적치할 필요가 있게 된다.Meanwhile, the support trolley 110 moved to the roller table 460 may be left as it is or may be transported to a separate place, but it is necessary to stack the support to dismantle the supporters.

이 경우가 발생되면, 작업자는 높이조절모터(448)를 회전시켜 잭스크류(450)와 스크류샤프트(452)를 이용하여 롤러테이블(460)의 일측단을 낮추게 되고, 이에 따라 서포트롤(110)은 경사가 낮은 쪽으로 굴러 떨어지게 된다.When this case occurs, the operator rotates the height adjustment motor 448 to lower one end of the roller table 460 by using the jackscrew 450 and the screw shaft 452, thereby supporting the support 110 Will roll down the slope.

이렇게 굴러 떨어진 서포트롤(110)은 롤가이드(480)로 안내되는데, 이때 서포트롤(110)은 롤가이드(480)를 타고 굴러내려가다가 완충핀(484)과 접촉되면서 회전속도가 줄어들게 되고, 완충핀(484)이 탄성적으로 접혀지는 순간 이를 타고 넘어 최종적으로 스토퍼(482)에 걸려 적치되게 된다.The rolled down supporter 110 is guided to the roll guide 480, in which the supporter 110 rolls down the roll guide 480 while being in contact with the buffer pin 484, thereby reducing the rotational speed. The moment that the pin 484 is elastically folded, the pin 484 rides over it and finally gets caught and stopped by the stopper 482.

이와 같은 과정을 반복적으로 수행함으로써 다수개의 해체된 서포트롤(110)을 롤적치대(400)에 적재할 수 있게 되어 작업의 편의성도 극대화된다.By repeatedly performing the above process, the plurality of disassembled support trolleys 110 can be loaded on the roll holder 400 to maximize the convenience of the work.
