본 고안은 용광로(blast furnace) 의 출선구를 막아주는 머드건 (mud gun) 에서 머드건노즐(mud gun nozzle)과 머드건 노즐팁(mud gun nozzle tip)과의 체결구조에 관한 것으로, 보다 상세히는 토글클램프(toggle clamp)를 이용하여 간편하게 체결 및 해체가 용이하도록 된 고로(高爐)출선구 폐쇄용 모드건노즐팁(mud gunnozzle tip) 체결구조에 관한 것이다.The present invention relates to a fastening structure between a mud gun nozzle and a mud gun nozzle tip in a mud gun that blocks the exit port of a blast furnace. The present invention relates to a mode gun nozzle tip fastening structure for closing a blast furnace exit port which is easily fastened and dismantled using a toggle clamp.

일반적으로 용광로에서 철강석용해작업이 진행되어 노저(爐低)에 용선이 고이게되면 4개의 출선구를 통해 용선이 노외(爐外)로 배출되고, 노저의 용선배출이 완료되면 고온의 바람과 함께 용선이 출선구로부터 분사, 비산되는 공취(空吹)현상이 일어나게 되고 이때 머드건(mud gun)을 사용하여 출선구를 폐쇄하게 된다.In general, when the molten steel is melted in the furnace and the molten iron is accumulated in the furnace, the molten iron is discharged to the outside of the furnace through four outlets. The molten iron is sprayed and scattered from the exit port, and then a mud gun is used to close the exit port.

상기 머드건(100)은 출선구(200)로 머드재(mud 材)를 충진하기 위한 머드건노즐(110)을 갖추고, 상기 머드건 노즐(110)을 보호하기위한 머드건 노즐팁(120)을 갖추고 있다.The mud gun 100 has a mud gun nozzle 110 for filling the mud material into the outlet 200, the mud gun nozzle tip 120 for protecting the mud gun nozzle 110 Equipped with.

상기 머드건(100)은 유압에 의해 300㎘/㎠의 고압으로 상기 출선구(200)를 폐쇄시키고, 머드건 노즐(110)과 머드건 노즐팁(120)으로 머드재(130)를 출선구 내부로 충진하여 출선구(200)를 폐쇄시키도록 작동한다. 그러나 상기 머드건(100)의 머드건노즐팁(120)이 출선구(200)와 충돌하게 될때에는 머드건 노즐팁(120)이 손상을입게하고, 상기 출선구(200)로 머드재(130)를 충진할때, 출선구(200)의 내화물과 머드건 노즐팁(120)이 일치하지 않게되어 머드재 가외부로 유출되는 현상이 발생하여 고로내의 조업상태가 악화되는 현상이 발생한다.The mud gun 100 closes the tap opening 200 at a high pressure of 300 kW / cm 2 by hydraulic pressure, and tapping the mud material 130 at the mud gun nozzle 110 and the mud gun nozzle tip 120. It fills up to operate to close the outlet 200. However, when the mud gun nozzle tip 120 of the mud gun 100 collides with the tap hole 200, the mud gun nozzle tip 120 is damaged, and the mud material 130 with the tap hole 200. ), When the refractory of the outlet 200 and the mud gun nozzle tip 120 is not matched, the phenomenon that the mud material is leaked to the outside occurs and the operation state in the blast furnace is deteriorated.

따라서, 작업자는 손상된 머드건 노즐팁(120)을 신속히 교체하여 출선구(200)을 폐쇄시켜야하는 것이다. 그러나, 종래의 머드건노즐(110)과 머드건노즐(120)은 한쌍의 핀(140)을 매개로 결합되어 있기때문에 상기 머드재(130)가 머드건노즐(110)과 머드건노즐팁(120) 사이로 누출되어 상기 핀(140)이 삽입된 핀구멍(150)으로 침입하면 상기 핀(150)을 해체하기가 매우 어려운 것이어서 아크용접기로 상기 머드건노즐팁(120)을 절단하여야하는 것이었다. 따라서, 장시간의 작업시간이 요구되고 머드건 노즐팁(120)을 재사용할 수 없는 문제점이 발생되었다.Therefore, the operator is to quickly replace the damaged mud gun nozzle tip 120 to close the outlet 200. However, since the mud gun nozzle 110 and the mud gun nozzle 120 are coupled to each other via a pair of pins 140, the mud material 130 is a mud gun nozzle 110 and a mud gun nozzle tip ( When the pin 140 leaks through the pin hole 150 inserted therein, it is very difficult to dismantle the pin 150, and the mud gun nozzle tip 120 should be cut by an arc welder. Therefore, a long working time is required and a problem arises in that the mud gun nozzle tip 120 cannot be reused.

본 고안은 상기와같은 문제점을 해소하기 위하여 안출된 것으로서, 단시간내에 용이하게 머드건노즐과 머드건 노즐팁을 결합, 분해시킬 수 있는 머드건 노즐팁 체결구조를 마련함에 그 목적이 있다.The present invention has been made to solve the above problems, the object of the present invention is to provide a mud gun nozzle tip fastening structure that can easily combine and disassemble the mud gun nozzle and mud gun nozzle tip in a short time.

상기 목적을 달성하기 위하여 본 고안은, 머드건노즐의 일측에 일정 크기의 플랜지부를 일체로 고정설치하고, 상기 플랜지부와 마주하는 머드건 노즐팁의 일측에 한쌍의 베이스(base)를 일체로 고정하며, 상기 베이스에 일체로 고정되어 상기 플랜지부를 상기 베이스에 결합시키는 한쌍의 토클클램프를 갖춘 고로출선구 폐쇄용머드건 노즐팁 체결구조를 마련함에 의한다.In order to achieve the above object, the present invention provides a fixed size integrally installed flange portion on one side of the mud gun nozzle, integrally a pair of base on one side of the mud gun nozzle tip facing the flange portion The blast furnace outlet opening mud gun nozzle tip fastening structure having a pair of toe clamps fixed to the base and integrally fixed to the base to couple the flange portion to the base.

이하, 본 고안을 도면에 의거 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the drawings.

본 고안의 체결구조(1)는 머드건 노즐(10)의 일측에 원주방향으로 돌출하도록 일정크기의 플랜지부(11)를 일체로 형성하고, 상기 플랜지부(11)와 마주하는 머드건 노즐팁(20)의 일측면에는 한쌍의 토글클램프(toggle clamp)(30)(30')의 베이스(31)(31')가 각각 일체로 고정된다. 상기 토글클램프(30)(30')는 각각 다수개의 핀과 링크로 구성된 공지의 것으로서 상기 베이스(31)(31')와 일체로 연결된 하부부재(32)(32')와, 상기 하부부재 (32)(32') 에 회전가능토록 결합된 걸고리형 상부부재(33)(33') 및, 상기 하부부재(32)(32')와 상부부재(33)(33')를 견고히 고정하여주는 보강링크(34)(34')가 다수개의 핀(35)으로 상기 상, 하부부재(32)(33)(32')(33')의 일측에 회전가능토록 고정되어 있다.The fastening structure 1 of the present invention integrally forms a flange portion 11 of a predetermined size so as to protrude in a circumferential direction on one side of the mud gun nozzle 10, the mud gun nozzle tip facing the flange portion 11 On one side of 20, a pair of base clamps 31 and 31 'of a toggle clamp 30 and 30' are fixed integrally. The toggle clamps 30 and 30 'are known in the art, and are composed of a plurality of pins and links, respectively, and include lower members 32 and 32' integrally connected to the base 31 and 31 ', and the lower member ( Hooks 32 and 32 'rotatably coupled to the hook-type upper members 33 and 33' and the lower members 32 and 32 'and the upper members 33 and 33' The reinforcing links 34 and 34 'are rotatably fixed to one side of the upper and lower members 32, 33, 32' and 33 'by a plurality of pins 35.

상기 보강링크(34)(34')의 중앙에 형성된 핀(35)에 작동레버(36)(36')의 일측이 회전가능토록 결합되고, 상기 토글클램프(30)(30')는 상기 머드건 노즐(10)의 플랜지부(11)에 토글클램프(30)(30')의 상부부재(33)(33')가 결합되어 상기 머드건 노즐(10)과 머드건 노즐팁(20)이 압입상태로 결합되도록 구성되어 있다.One side of the actuating levers 36 and 36 'is rotatably coupled to the pin 35 formed at the center of the reinforcing links 34 and 34', and the toggle clamps 30 and 30 'are coupled to the mud. The upper members 33 and 33 'of the toggle clamps 30 and 30' are coupled to the flange 11 of the gun nozzle 10 so that the mud gun nozzle 10 and the mud gun nozzle tip 20 It is configured to be coupled in a press-fit state.

미설명 부호 (40)는 캡이고 (300)는 고로벽체이다.Reference numeral 40 is a cap and 300 is a blast furnace wall.

상기와 같이 구성된 본 고안의 작용 및 효과에 대하여 설명한다. 먼저, 머드건 노즐(10)을 머드건 노즐팁(20)에 형성된 삽입구(20a)에 밀착시키고, 상기 토글클램프(30)(30')의 작동레버(36)(36')를 상부로 젖혀서 상부부재(33)(33')의 걸고리 내측면을 상기 플랜지부(11)의 일측에 각각 끼운다.It describes the operation and effects of the present invention configured as described above. First, the mud gun nozzle 10 is brought into close contact with the insertion opening 20a formed in the mud gun nozzle tip 20, and the operation levers 36 and 36 'of the toggle clamps 30 and 30' are flipped upward. The hook inner surface of the upper members 33, 33 'is fitted to one side of the flange portion 11, respectively.

그리고 상기 작동레버(36)(36')를 아래로 젖히면 보강링크(34)(34')가 일(-)자형으로 퍼지면서 토글클램프(30)(30')는 상기 머드건 노즐(10)의 플랜지부(11)와 머드건노즐팁(20)일측을 견고히 고정하게 된다.When the operation levers 36 and 36 'are flipped down, the reinforcing links 34 and 34' are spread in a single (-) shape, and the toggle clamps 30 and 30 'are connected to the mud gun nozzle 10. The flange portion 11 and the mud gun nozzle tip 20 of one side will be firmly fixed.

상기와 같은 상태에서 머드건 노즐팁(20)에 손상이 가해지게 되어 머드건 노즐팁(20)을 머드건 노즐(10)로부터 분리시키기 위해서는 단순히 작동레버(36)(36')를 보강링크(34)(34')의 상부로 젖히기만 하면 토글클램프(30)(30')가 결합상태에서 분리상태로 되어 머드건 노즐팁(20)을 머드건노즐(10)로부터 용이하게 분리시킬 수가 있다.Damage to the mud gun nozzle tip 20 in the above state is to simply remove the mud gun nozzle tip 20 from the mud gun nozzle 10 by simply actuating the link (36, 36 ') Toggle the clamp clamp 30 and 30 'in a coupled state by simply flipping it to the top of the 34) 34' to easily remove the mud gun nozzle tip 20 from the mud gun nozzle 10. .

상기와 같이 본 고안에 의하면 토글클램프(30)(30')를 이용하여 머드건노즐(10)과 머드건노즐팁(20)을 체결하고 분리시키기 때문에 상기 작업이 매우 간편하게 되고, 머드건 노즐팁(20)을 아크 용접기로 절단할 필요가 없기 때문에 손상된 머드건 노즐팁(20)을 보수하여 재사용할 수 있게되어 원가절감의 효과도 얻을 수 있게 된다.According to the present invention as described above, since the mud gun nozzle 10 and the mud gun nozzle tip 20 are fastened and separated by using the toggle clamps 30 and 30 ', the operation becomes very simple, and the mud gun nozzle tip Since the 20 does not need to be cut by an arc welder, the damaged mud gun nozzle tip 20 can be repaired and reused, thereby achieving cost reduction effects.
