Description
본 고안은 턴디쉬내의 필러혼입 방지장치에 관한 것으로, 특히 레이들의 필러가 턴디쉬내의 용강에 혼입되는 것을 방지하기 위한 턴디쉬내의 필러혼입 방지장치에 관한 것이다.The present invention relates to a filler mixing prevention device in a tundish, and more particularly, to a filler mixing prevention device in a tundish for preventing the ladle's filler from being mixed in the molten steel in the tundish.
도1에 도시한 바와 같이 턴디쉬(110)중 롱노즐(35)과 턴디쉬 간의 실링( Sealing)이 완벽하지 않은 개방형 타입에서는 레이들(100)로부터 유출되는 필러(Filer)(50)가 롱노즐(35)을 통해 용강과 함께 턴디쉬내로 필연적으로 유입된다.As shown in FIG. 1, in the open type in which the sealing between the long nozzle 35 and the tundish is not perfect, the filler 50 flowing from the ladle 100 is long. It inevitably flows into the tundish with the molten steel through the nozzle 35.
이때, 턴디쉬(110)내로 유입되는 필러는 용강의 탕면위로 부상되지 않고 그대로 용강내에 혼재된 상태로 다시 침지노즐을 통해 몰드로 혼입되어 주편의 품질에 악영향을 끼치게 된다.At this time, the filler introduced into the tundish 110 is not injured on the hot water surface of the molten steel and mixed into the mold again as it is mixed in the molten steel, thereby adversely affecting the quality of the cast steel.
따라서, 종래에는 연속주조의 초기 주편을 제품화하지 않고 전량 스크랩 또는 여재 형태의 제품으로 불출하여 불필요한 낭비를 초래하면서 생산성을 저하시키고, 제품의 품질을 저하시키는 등의 문제점이 있었다.Therefore, conventionally, the initial cast of the continuous casting is not produced as a product in the form of scrap or media in the form of the whole amount of waste, causing unnecessary waste, there is a problem such as lowering the productivity, lowering the quality of the product.
본 고안은 롱노즐에 장착되어 레이들의 필러가 턴디쉬내의 용강에 혼입되는 것을 방지함으로써 불필요한 주편의 낭비를 줄이고, 주편의 품질을 향상시키며, 생산성을 높일 수 있는 턴디쉬내의 필러혼입 방지장치를 제공함에 그 목적이 있다.The present invention provides a filler mixing prevention device in a tundish that can be installed in a long nozzle to prevent the ladle's filler from being mixed in the molten steel in the tundish, thereby reducing unnecessary waste of cast steel, improving the quality of the cast steel, and increasing productivity. Has its purpose.

Fig. 7 is a state diagram showing the working state of the mixing prevention device, and Fig. 7 is a state diagram showing the molten state after the filler collecting pipe falls into the tundish of the filler mixing prevention device in the tundish according to the present invention.
롱노즐(35)의 직경과 동일한 또는 다소의 여유직경을 갖도록 형성된 원통형상의 필러수집관(11)은 그 상부가 개방되면서 그 하부가 밀폐되도록 형성되어 있고, 그 외주면 상단부에 한쌍의 로크핀홈(12)이 대칭적으로 형성되어 있다.The cylindrical filler collecting pipe 11 formed to have the same or somewhat free diameter as the diameter of the long nozzle 35 is formed so that its lower part is sealed while its upper part is opened, and a pair of lock pin grooves 12 are formed at the upper end of its outer peripheral surface. ) Are symmetrically formed.
이때, 필러수집관(11)에는 그 내주면 중단부에 고정대(17)가 고정되어 있고, 이 고정대에 원형의 편심판(14)이 고정핀(15)을 중심으로 편심 회전되도록 결합되면서 스토퍼(16)에 의해 지지되도록 설치되어 있다.At this time, the filler collection pipe 11 is fixed to the stopper 17 is fixed to the inner peripheral surface of the stop, the circular eccentric plate 14 is coupled to the stopper 16 while being coupled to the eccentric rotation around the fixing pin 15 It is installed to be supported by).
또한, 필러수집관(11)의 주벽에는 편심판(14)의 상부에 위치하도록 용강배출구(13)가 형성되어 있고, 이 용강배출구를 통해 필러수집관내에 충전되는 용강이 오버플로(Overflow)되어 턴디쉬(110)로 배출된다.In addition, the molten steel discharge port 13 is formed on the circumferential wall of the filler collection pipe 11 so as to be positioned above the eccentric plate 14, and the molten steel filled in the filler collection pipe overflows through the molten steel discharge port. Discharged to the tundish 110.
한편, 지그(30)의 지그암(32)에는 그 상부측에 롱노즐(35)를 지지하는 지그링(34)이 회전 가능하도록 설치되어 있고, 그 하부측에 로크핀프레임(31)이 형성되어 있다.On the other hand, a jig ring 34 supporting the long nozzle 35 is rotatably installed on the jig arm 32 of the jig 30, and a lock pin frame 31 is formed on the lower side thereof. It is.
이때, 로크핀프레임(31)에는 그 외측면에 로크핀하우징(40)이 고정 부착되어 있고, 이 로크핀하우징(40) 내에는 로크핀(41)이 압축스프링(43)에 의해 탄성이동을 하도록 설치되어 있다.At this time, a lock pin housing 40 is fixedly attached to the outer surface of the lock pin frame 31, and the lock pin 41 is elastically moved by the compression spring 43 in the lock pin housing 40. It is installed to
여기서, 로크핀(41)은 로크핀프레임(31)을 관통하여 로크핀프레임의 내측면으로 돌출되도록 설치되어 있고, 또한 로크핀홈(12)에 삽입되어 필러수집관(11)을 지지하게 된다.Here, the lock pin 41 is installed to penetrate the lock pin frame 31 to protrude toward the inner surface of the lock pin frame, and is also inserted into the lock pin groove 12 to support the filler collection pipe 11.
이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.
지그링(34)을 롱노즐(35)에 끼운 후, 필러수집관(11)을 롱노즐(35)의 하부를 통하여 밀어 올려 끼우게 되는데, 이때 필러수집관(11)의 로크핀홈(12)에 로크핀(41)이 탄성적으로 삽입되면서 필러수집관은 로크핀프레임(31)에 고정되어지게 된다.After inserting the jig ring 34 into the long nozzle 35, the filler collecting pipe 11 is pushed up through the lower part of the long nozzle 35, in which the lock pin groove 12 of the filler collecting pipe 11 is inserted. The lock pin 41 is elastically inserted into the filler collecting tube is fixed to the lock pin frame 31.
그리고, 지그(30)를 이용한 연속주조작업의 통상작업으로 시작되는 레이들(100)의 하부의 콜렉트노즐(20)에 롱노즐(35)을 밀착하여 고정시킨 다음, 레이들내에 수용되어 있는 용강을 유출시키게 된다.Then, the long nozzle 35 is fixed in close contact with the collect nozzle 20 of the lower part of the ladle 100, which starts with the normal operation of the continuous casting operation using the jig 30, and then the molten steel accommodated in the ladle. Will leak.
이때, 톱노즐(9)내의 필러(50)는 롱노즐(35)에 안내되어 필러수집관(11)내에서 편심판(14)에 쌓이게 되고, 동시에 필러와 함께 필러수집관내에 수용되는 용강은 핀심판(14)을 산화시키면서 필러수집관내를 차올라 오게된다.At this time, the filler 50 in the top nozzle 9 is guided to the long nozzle 35 and accumulated in the eccentric plate 14 in the filler collecting pipe 11, and at the same time, the molten steel accommodated in the filler collecting pipe together with the filler is The pin core plate 14 is oxidized to fill up the filler collection pipe.
여기서, 필러수집관(11)내에 충전되는 용강은 필러(50)와 접하는 계면층이 필러와 반응하여 슬래그상태로 변하고, 계속 그 충전레벨이 상승되면서 용강배출구(13)를 통해 오버플로(Overflow)되어 턴디쉬(110)로 유출된다.Here, the molten steel to be filled in the filler collection pipe 11 is changed into a slag state in response to the filler and the interface layer in contact with the filler 50, the overflow through the molten steel outlet 13 as the filling level is continuously raised. And flows out to the tundish 110.
또한, 이러한 필러(50)의 분리작업 및 용강의 배출작업이 진행되면서 필러수집관(11)은 편심판(14)의 상부에 누적되는 필러와 용강의 중량에 의해 그 자중이 증가하게 되고, 마침내 스프링(43)의 탄성력을 이기고 로크핀홈(12)에 삽입되어 있는 로크핀(41)을 후진시켜 로크핀프레임(31)으로부터 분리된다.In addition, as the separation operation of the filler 50 and the discharge operation of the molten steel proceeds, the filler collection pipe 11 has its own weight increased by the weight of the filler and the molten steel accumulated on the eccentric plate 14, and finally, The lock pin 41 inserted into the lock pin groove 12 is reversed to overcome the elastic force of the spring 43 and separated from the lock pin frame 31.
따라서, 필러수집관(11)은 턴디쉬(110)내로 자유낙하하게 되고, 필러수집관과 필러(50)는 턴디쉬내에서 용융되면서 용강 탕면으로 부상되어 슬래그층(202)을 형성하게 된다.Therefore, the filler collection tube 11 freely falls into the tundish 110, and the filler collection tube and the filler 50 are melted in the tundish and floated on the molten steel surface to form the slag layer 202.
한편, 연연주작업에 있어서 필러(50)의 제거는 초기 연주시의 용강레이들(100)내 필러만 제거하면 되고, 다음 용강레이들의 연연주시 필러는 용강과의 비중차에 의해 턴디쉬(110)내의 슬래그층(202)으로 부상된다.On the other hand, the removal of the filler 50 in the performance cast only need to remove the filler in the molten steel ladle 100 during the initial performance, the filler during the performance of the next molten steel ladle is tundish 110 by the difference in specific gravity with the molten steel 110 Floats into the slag layer 202 within.
본 고안은 롱노즐에 장착되어 레이들의 필러가 턴디쉬내의 용강에 혼입되는 것을 방지함으로써 불필요한 주편의 낭비를 줄이고, 주편의 품질을 향상시키며, 생산성을 높일 수 있는 효과를 제공한다.The present invention is installed in the long nozzle to prevent the ladle filler from being mixed in the molten steel in the tundish to reduce the waste of unnecessary cast steel, improve the quality of the cast steel, and provide an effect to increase the productivity.
