Description
본 고안은 주조래들(Casting Ladle)의 필러(Filler)투입장치에 관한 것으로, 특히 주조래들의 용강을 턴디쉬에 용이하게 출강할 수 있도록 투입되는 필러를 이물질(지금 및 슬래그 등)에 의해 막혀있는 턴디쉬의 노즐구를 개공한 후 턴디쉬의 노즐구에 투입하는 주조래들(Casting Ladle)의 필러(Filler)투입장치에 관한 것이다.The present invention relates to a filler injection device of casting ladle, and in particular, a filler that is injected to easily tap the molten steel of the casting ladle into a tundish is blocked by foreign matter (now and slag). The present invention relates to a filler injection device for casting ladles which is opened after opening a nozzle hole of a tundish, which is put into a nozzle hole of a tundish.
일반적으로, 연속주조작업은 주조래들 내에 수강된 용강을 노즐구와 슈라이드노즐을 통해 연주턴디쉬로 출강되는데, 이때 노즐구을 통한 용강의 방출을 돕기 위하여 노즐구내로 래들필러가 투입된다.In general, the continuous casting operation is carried out to the playing tungdish through the nozzle hole and the shroud nozzle in the molten steel received in the casting ladle, the ladle filler is introduced into the nozzle hole to help discharge the molten steel through the nozzle hole.
그러나, 도1에 도시한 바와같이 주조래들(1)의 내주면 선단에 부착되어 있던 융착슬래그(2)가 탈락되면서 탈락슬래그(3)로 주조래들의 바닥에 떨어지고, 탈락슬래그(3)의 일부는 노즐구(4)내로 혼입되어 노즐구의 내주면에 고착되면서 출강을 방해하게 된다.However, as shown in FIG. 1, the fusion slag 2 attached to the tip of the inner circumferential surface of the casting ladle 1 falls off and falls to the bottom of the casting ladle as the dropping slag 3, and a part of the falling slag 3 is removed. Is mixed into the nozzle hole 4 and stuck to the inner circumferential surface of the nozzle hole, thereby hindering tapping.
한편, 종래의 노즐구(4)에 고착된 이물질 제거방법은 여러 가지 있으나 모두 작업자가 직접 수행하기 때문에 화상 및 추락 등의 안전사고 위험이 높고, 작업이 매우 비능률적인 문제가 있다.On the other hand, there are a number of methods for removing foreign matters fixed to the conventional nozzle port 4, but all are directly performed by an operator, so there is a high risk of safety accidents such as burns and falls, and work is very inefficient.
본 고안은 주조래들의 용강을 턴디쉬에 용이하게 출강할 수 있도록 투입되는 필러를 이물질(지금 및 슬래그 등)에 의해 막혀있는 턴디쉬의 노즐구를 개공한 후 턴디쉬의 노즐구에 투입하는 주조래들(Casting Ladle)의 필러(Filler)투입장치를 제공함에 그 목적이 있다.The main idea is to open the nozzle hole of the tundish, which is blocked by foreign substances (now and slag, etc.) and put it into the nozzle hole of the tundish. It is an object of the present invention to provide a filler injection device of casting ladles.

본 고안에 따른 필러투입관(6)은 외주면과 내주면 사이에 에어공급로(8)가 형성되어 있고, 그 상단에 에어공급로(8)와 연결되는 에어공급관(16)이 결합되어 있으며, 이 에어공급관(16)의 하단에는 수퀵커플링(10-1)이 부착되어 있다.The filler input pipe 6 according to the present invention has an air supply path 8 formed between an outer circumferential surface and an inner circumferential surface thereof, and an air supply pipe 16 connected to the air supply path 8 is coupled to an upper end thereof. The male quick coupling 10-1 is attached to the lower end of the air supply pipe 16.
이때, 필러투입데크(9)의 상부에는 고정대(21)에 의해 에어공급라인(18)이 고정 지지되어 있고, 이 에어공급라인(18)의 상단에는 암퀵커플링(10-2)이 결합되어 있으며, 이 암퀵커플링(10-2)에는 필러투입관(6)에 의해 상하강되는 수퀵커플링(10-1)이 단속된다.At this time, the air supply line 18 is fixedly supported by the holder 21 on the upper portion of the filler input deck 9, and the female quick coupling 10-2 is coupled to the upper end of the air supply line 18. The male quick coupling 10-2 is interrupted by a male quick coupling 10-1 which is vertically lowered by the filler injection pipe 6.
그리고, 필러투입관(6)의 하단에는 에어공급로(8)와 연결되는 ＋자형의 연결관(11)이 설치되어 있고, 이 연결관(11)의 중앙에는 노즐관(12)의 상단이 연통되도록 결합되어 있다.In addition, a + -shaped connecting pipe 11 connected to the air supply path 8 is provided at the lower end of the filler input pipe 6, and an upper end of the nozzle pipe 12 is formed at the center of the connecting pipe 11. Combined to communicate.
여기서, 필러투입관(6)을 통해 투입되는 래들필러는 연결관(11)의 사이 공간을 통해 하부로 낙하되어 노즐구(4)에 충전된다.Here, the ladle filler injected through the filler input pipe 6 is dropped downward through the space between the connection pipe 11 and filled in the nozzle port 4.
또한, 연결관(11)을 통해 에어가 공급되는 노즐관(12)에는 그 내주면 중단부에 ＋자형의 고정대(19)가 고정되어 있고, 이 고정대(19)의 중앙에는 회전축(22)이 상하이동 및 회전가능하도록 관통되어 있다.In addition, a + -shaped holder 19 is fixed to the stopper portion 12 of the inner circumferential surface of the nozzle tube 12 through which the air is supplied through the connecting pipe 11, and the rotating shaft 22 is vertically disposed at the center of the holder 19. It is penetrated to be movable and rotatable.
이때, 회전축(22)의 상단에는 ＋자형의 이동대(20)가 고정 결합되어 있고, 이 이동대(20)와 고정대(19) 사이에 위치하도록 압축스프링(13)이 회전축(22)에 결합되어 있다.At this time, the + -shaped moving table 20 is fixedly coupled to the upper end of the rotating shaft 22, and the compression spring 13 is coupled to the rotating shaft 22 so as to be located between the moving table 20 and the fixing table 19. It is.
그리고, 고정대(19)의 하부측에 위치하는 회전축(22)에는 다수의 프로펠러(14)와 드릴봉(15)이 차례로 체결되어 있고, 이 드릴봉(15)은 노즐구(4)내에 고착되어 있는 이물질을 용이하게 파쇄분화시키기 위하여 원추형으로 형성되면서 그 외주면에 나선형의 홈이 형성되어 있다.A plurality of propellers 14 and a drill rod 15 are fastened in turn to the rotary shaft 22 positioned on the lower side of the fixed base 19, and the drill rod 15 is fixed in the nozzle hole 4. Spiral grooves are formed on the outer circumferential surface of the outer circumferential surface while being formed in a conical shape in order to easily break apart the foreign matter.
이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.
먼저, 정련로에서 취련 완료된 용강을 주조래들(1)에 수강하기 전에 노즐구(4)내에 이물질 막힘을 유안으로 확인한 후, 노즐구가 이물질에 의해 막힘이 확인되면 래들필러를 투입하기 전에 노즐구를 개방하기 위하여 필러투입관(6)을 가이드롤러(7)를 따라 하강시키고, 수퀵커플링(10-1)을 암퀵커플링(10-2)에 결합시키면서 노즐관(12)을 노즐구(4)의 상부측에 삽입시킨다.First, before the molten steel that has been blown in the refining furnace is taken into the casting ladle 1, the clogging of foreign matter in the nozzle hole 4 is visually confirmed. If the nozzle hole is confirmed to be blocked by foreign matter, the nozzle before the ladle filler is introduced. In order to open the sphere, the filler input pipe 6 is lowered along the guide roller 7, and the nozzle pipe 12 is connected to the nozzle hole while the male quick coupling 10-1 is coupled to the female quick coupling 10-2. Insert it into the upper side of (4).
이때, 수퀵커플링(10-1)에 의해 암퀵커플링(10-2)이 개방되면서 에어공급라인(18)의 고압에어가 필러투입관(6)의 내부에 형성되는 에어공급로(8)를 통해 연결관(11)를 거쳐 노즐관(12)에 공급된다.At this time, the female quick coupling 10-2 is opened by the male quick coupling 10-1, and the air supply passage 8 in which the high pressure air of the air supply line 18 is formed inside the filler input pipe 6 is provided. It is supplied to the nozzle pipe 12 via the connecting pipe 11 through.
그리고, 노즐관(12)에 공급된 에어는 빠른 속도로 하강되면서 프로펠러(14)를 회전시키게 되고, 프로펠러는 에어에 의해 탄성적으로 상하강되면서 드릴봉(15)을 회전시키게 된다.Then, the air supplied to the nozzle tube 12 is lowered at a high speed to rotate the propeller 14, the propeller is rotated up and down elastically by the air to rotate the drill rod 15.
여기서, 탄성적으로 상하강되면서 회전되는 드릴봉(15)은 노즐구(4)의 내측에 고착되어 있는 이물질(17)을 파쇄분화시키고, 파쇄분화된 이물질은 노즐관(12)으로 하향 분사되는 에어에 의해 노즐구의 상부측으로 분출되어 노즐관을 개방시키게 된다.Here, the drill rod 15 is rotated while elastically up and down to crush the foreign matter 17 is fixed to the inside of the nozzle hole 4, the crushed foreign matter is injected downward into the nozzle tube 12 The air is blown to the upper side of the nozzle port to open the nozzle tube.
한편, 이물질(17)에 의해 막혀있던 노즐구(4)가 개방되면 다시 필러투입관(6)을 가이드롤러(7)를 따라 상승시켜 수퀵커플링(10-1)을 암퀵커플링(10-2)으로부터 분리시킨다.On the other hand, when the nozzle port 4 blocked by the foreign matter 17 is opened, the filler input pipe 6 is again raised along the guide rollers 7 so that the male quick coupling 10-1 is female quick coupling 10-. From 2).
이때, 수퀵커플링(10-1)이 암퀵커플링(10-2)과 분리되면 필러투입관(6)의 상승을 멈추고 필러투입관을 통해 래들필러를 투입하여 노즐구(4)에 충전시킨 후, 다시 필러투입관을 상승시켜 필러투입데크(9)로부터 취외하면 래들필러투입작업은 완료된다.At this time, when the male quick coupling 10-1 is separated from the female quick coupling 10-2, the filler input pipe 6 stops rising, and the ladle filler is introduced through the filler input tube to fill the nozzle port 4. After that, when the filler injection pipe is raised again and taken out from the filler injection deck 9, the ladle filler injection operation is completed.
본 고안은 주조래들의 용강을 턴디쉬에 용이하게 출강할 수 있도록 투입되는 필러를 이물질(지금 및 슬래그 등)에 의해 막혀있는 턴디쉬의 노즐구를 개공한 후 턴디쉬의 노즐구에 투입함으로써 작업의 생산성을 향상시키고, 안전사고를 예방할 수 있는 효과를 제공한다.The present invention works by opening the nozzle of the tundish which is blocked by foreign substances (now and slag, etc.) and putting it into the trough of the tundish after filling the filler to easily cast the molten steel of the cast ladle into the tundish. Improve productivity and prevent safety accidents.
