Description
본 발명은 쌍롤형 박판주조기에서 잔탕에 의해 발생되는 자국을 제거하기 위하여 오일을 분사하는 장치에 관한 것으로, 보다 상세히는 주조중 발생되는 긴급상황이나 주조말기에 주조롤이 벌어질 때 용강의 잔탕에 의하여 롤표면에 자국이나 불순물이 남지 않도록 수동 또는 자동으로 롤표면으로 오일을 분사하는 쌍롤형 박판주조기의 롤마크제거용 오일분사장치에 관한 것이다.The present invention relates to an apparatus for injecting oil to remove traces generated by residual water in a twin-roll type sheet casting machine, and more particularly, to a molten steel residual water when a casting roll occurs at an emergency or during the end of casting. The present invention relates to an oil spray device for removing a roll mark of a twin roll type sheet casting machine which sprays oil onto a roll surface manually or automatically so that marks or impurities remain on the roll surface.
일반적으로 쌍롤형 박판주조기(100)는 도 1에 도시한 바와같이, 래들로부터 용강을 받는 턴디쉬에서 용강주입용 주입노즐(4)을 통하여 미도시된 구동장치에 의해서 서로 반대방향으로 회전하는 쌍롤(이하 주조롤이라 한다.)(1)(1a)사이로 용강을 주입하여 마주하는 주조롤(1)(1a)과 에지댐(2)사이에 용탕풀(5)을 형성하고, 회전하는 주조롤(1)(1a)과 용강의 접촉을 통하여 용강을 급속응고하여 응고쉘을 형성하면서 박판(6)을 주조하는 설비이다.In general, the twin-roll sheet caster 100 is rotated in the opposite direction by a driving device not shown through a molten steel injection nozzle 4 in the tundish receiving the molten steel from the ladle as shown in FIG. (Hereinafter referred to as casting roll) (1) (1a) to form a molten steel between the casting roll (1) (1a) and the edge dam (2) facing the molten steel is injected to rotate the casting roll (1) A facility for casting a thin plate 6 while rapidly solidifying molten steel through contact between the molten steel and the molten steel to form a solidified shell.
이러한 쌍롤형 박판주조기(100)를 이용한 주조작업중 긴급상황이 발생되거나 주조를 끝내고 마주하는 주조롤(1)(1a)사이의 갭(gap)이 벌어질 때, 상기 주조롤(1)(1a)사이에 남아 있던 용강이나 불순물(이하 잔탕이라 한다.)이 빠져나가면서 잔탕과 주조롤(1)(1a)사이에 순간적인 융착이 발생되고, 이러한 잔탕의 융착에 의하여 상기 주조롤(1)(1a)의 외표면에 자국(mark)을 남기거나 불순물이 잔류된다.The casting roll (1) (1a) when an emergency occurs during the casting operation using the twin roll-type sheet casting machine (100) or a gap between the casting rolls (1) (1a) facing each other after finishing casting occurs. As the molten steel or impurities (hereinafter referred to as residual water) remaining in between flow out, an instantaneous fusion occurs between the residual water and the casting roll (1) (1a), and the casting roll (1) ( Marks or impurities remain on the outer surface of 1a).
상기와 같이 주조롤(1)(1a)의 표면에 남게 되는 자국은 다음 연속주조에서 초기박판(6)의 표면에 자국을 그대로 전사하게 되어 상기 박판(6)의 품질을 저하시키고, 열전달측면에서도 영향을 주어 자국이 남아있는 주조롤(1)(1a)부위에서는 열전달이 더 잘되어 상기 주조롤(1)(1a)의 고른 롤폭방향으로의 열전달분포에 악영향을 미치는 한편, 상기 잔탕에 존재하고, 주조롤(1)(1a)의 롤표면에 잔류하는 불순물내의 산화망간에 의해서 롤표면이 오염될 우려가 매우 높다.As described above, the marks remaining on the surface of the casting rolls 1 and 1a are transferred as they are to the surface of the initial thin plate 6 in the subsequent continuous casting, thereby degrading the quality of the thin plate 6 and in terms of heat transfer. The heat transfer is better in the casting roll (1) (1a) where the mark remains and thus adversely affects the heat transfer distribution in the even roll width direction of the casting roll (1) (1a), while it is present in the residue. There is a high possibility that the roll surface will be contaminated by manganese oxide in impurities remaining on the roll surface of the casting rolls 1 and 1a.
이에 따라, 잔탕에 의해 발생되는 롤자국이 발생되고, 불순물이 롤표면에 잔류하는 것을 방지하기 위하여 연주공장에서 몰드파우더(mold pwder)를 윤활목적으로 사용하는 것을 박판주조기에 적용할수 있지만, 파우더와 같은 소재가 용강에 혼입되면 주편의 표면에 악영향을 미치게 되므로 이를 채용하기는 곤란하다.As a result, it is possible to apply a thin mold casting machine to lubrication of a sheet casting machine in order to prevent roll marks generated by residing and to prevent impurities from remaining on the roll surface. If the same material is mixed in the molten steel, it will be adversely affected on the surface of the cast steel, so it is difficult to employ it.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해서 안출된 것으로서, 그 목적은, 주조말기나 긴급상황 발생시 주조롤사이의 갭이 벌어지면서 잔탕이 빠져나갈 때 주조롤의 표면상으로 오일을 분사하여 잔탕의 융착에 의해서 발생되는 롤자국 및 분술물이 잔류하는 것을 방지하는 쌍롤형 박판주조기의 롤자국 제거용 오일분사장치를 제공하고자 한다.Accordingly, the present invention has been made in order to solve the above problems, the object of the present invention is to spray oil on the surface of the casting roll when the residual water is released while the gap between the casting rolls open during the end of the casting or emergency situation It is an object of the present invention to provide an oil spraying device for removing roll marks of a twin roll type sheet casting machine, which prevents the roll marks and the powders generated by fusion of residues from remaining.

상기한 구성을 갖는 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention having the above configuration is as follows.
먼저, 마주하는 주조롤(1)(1a)사이에 용탕풀(5)을 형성하여 박판(6)을 주조하는 말기 또는 주조도중 긴급한 상황이 발생되어 상기 주조롤(1)(1a)의 갭사이의 벌어짐과 동시에, 상기 주조롤(1)(1a)의 갭이 벌어지는 신호가 주조정실에 전송되면, 이를 수신한 주조정실에서 오일공급라인(18)의 길이중간에 장착된 솔레노이드밸브(18b)를 닫힘상태에서 열림상태로 전환시킨다.First, an urgent situation occurs during the final stage of casting or casting of the thin plate 6 by forming the molten metal pool 5 between the casting rolls 1 and 1a facing each other, and thus, between the gaps of the casting rolls 1 and 1a. At the same time, when the gap between the casting rolls 1 and 1a is transmitted to the main control chamber, the solenoid valve 18b mounted in the middle of the length of the oil supply line 18 is closed in the main control chamber. Switch to open.
이러한 경우, 개방된 솔레노이드밸브(18b)과 오일공급라인(18)을 통하여 오일탱크(19)내의 오일은 상기 주조롤(1)(1a)과 서로 나란하게 롤폭방향으로 1열 또는 2열이상의 복수열로 장착된 각 오일분사관(13)측으로 공급되고, 공급된 오일은 상기 오일분사관(13)에 형성된 노즐공(14)을 통해 분사되어 주조롤(1)(1a)의 표면을 코팅(coating)함으로서 잔탕이 롤표면과 순간 융착되면서 롤표면에 자국을 발생하거나 산화망간과 같은 불순물이 롤표면에 남아 롤표면을 오염시키는 것을 방지할수 있는 것이다.In this case, the oil in the oil tank 19 through the open solenoid valve 18b and the oil supply line 18 is parallel to the casting rolls 1 and 1a in a roll width direction in a plurality of rows or rows or more. Heated oil is supplied to each side of the oil spray pipe 13, the supplied oil is sprayed through the nozzle hole 14 formed in the oil spray pipe 13 to coat the surface of the casting roll (1) (1a) ( By coating, it is possible to prevent residues from being fused to the surface of the roll and to generate marks on the surface of the roll or to leave impurities such as manganese oxide on the surface of the roll to contaminate the surface of the roll.
즉, 상기 오일분사관(13)의 오일분사는 주조말기 또는 긴급상황발생시 주조롤(1)(1a)의 갭이 벌어지는 신호에 연동하여 상기 주조롤(1)(1a)의 벌어짐과 동시에 오일을 롤표면으로 분사하도록 상기 솔레노이드밸브(18b)를 개방한다.That is, the oil spray of the oil spray pipe 13 is connected to the signal that the gap of the casting roll (1) (1a) when the end of the casting or emergencies occur in conjunction with the opening of the casting roll (1) (1a) at the same time The solenoid valve 18b is opened to spray on the roll surface.
여기서, 상기 오일분사관(13)의 노즐공(14)을 통해 주조롤(1)(1a)의 표면을 코팅하도록 분사되는 오일은 레이프시드 오일(rape-seed oil)을 사용하는 것이 좋다.Here, the oil sprayed to coat the surface of the casting rolls 1 and 1a through the nozzle hole 14 of the oil spray pipe 13 may use a rape-seed oil.
그리고, 상기 오일분사관(13)의 노즐공(14)을 통한 오일분사는 설정된 수초 동안 이루어진 후에 상기 솔레노이브밸브(18b)의 자동 닫힘동작에 의해서 자동으로 중단된다.Then, the oil injection through the nozzle hole 14 of the oil injection pipe 13 is automatically stopped by the automatic closing operation of the solenoid valve 18b after a few seconds set.
한편, 상기 오일분사관(13)을 외부로 인출하여 수리하거나 교체하고자 하는 경우, 상기 관홀더(12)에 조립된 조임나사(12c)를 풀어 슬릿(12b)의 간격을 원상태로 넓히면, 상기 슬릿(12b)에 연결된 반원단면의 조립홈(12a)이 확대되면서 상기 오일분사관(13)에 대한 취부력이 해제되어 이를 간편하게 외부로 인출할 수 있다.On the other hand, when the oil spray pipe 13 to be drawn out to repair or replace, if the loosening the screw 12c assembled in the tube holder 12 to widen the interval of the slit 12b to the original state, the slit As the assembling groove 12a of the semicircular cross-section connected to 12b is expanded, the mounting force on the oil spray pipe 13 is released and it can be easily taken out to the outside.
상술한 바와같은 본 발명에 의하면, 쌍롤형 박판주조기에서 주조말기 또는 긴급상황발생시 주조롤의 갭이 벌어지는 신호에 연동하여 주조롤의 벌어짐과 동시에 오일을 롤표면으로 분사함으로서, 잔탕에 의해서 남는 자국과 산화망간과 같은 불순물이 롤표면에 남지 않게할수 있기 때문에 연속되는 박판주조에서 초기박판이 품질을 향상시킬수 있고, 롤 폭방향으로 고른 열전달분포를 보장하여 우수한 품질의 박판을 제조할수 있는 효과가 얻어진다.According to the present invention as described above, in the twin-roll type sheet casting machine in conjunction with the signal that the gap of the casting roll when the end of the casting or emergencies occurs, by spraying the oil on the roll surface at the same time as the gap of the casting roll is opened, Since impurities such as manganese oxide do not remain on the surface of the roll, the initial sheet can improve the quality in continuous sheet casting, and it is possible to guarantee the excellent heat transfer distribution in the roll width direction, thereby producing an excellent sheet. .
