Description

고로 노벽 보수장치Blast Furnace Wall Repair
본 발명은 고로 노벽 보수장치에 관한 것이다.The present invention relates to a blast furnace furnace wall repair apparatus.
일반적으로 고로 공정은 고로 상부의 장입구를 통해서 연료인 코크스와 원료인 철광석을 장입하고 고로 하부에 있는 풍구를 통해서 고온의 열풍을 불어넣어 코크스를 연소시켜 열과 환원가스를 만들고 열과 환원가스는 노내의 철광석을 환원용융시켜 용선과 슬래그를 생성하게 되며 용융물은 고로 하부의 출선구를 통해서 배출된다. In general, the blast furnace process charges coke as fuel and iron ore as raw materials through the charging hole in the upper part of the blast furnace, and blows coke by blowing high temperature hot air through the blast holes at the bottom of the blast furnace to produce heat and reducing gas. Iron ore is reduced and melted to produce molten iron and slag, and the melt is discharged through the outlet at the bottom of the blast furnace.
이러한 본체 구조는 외부가 철피로 되어 있고 내부에는 고온의 열과 가스에 견딜 수 있는 고강도 내화물이 축조되어 있고 내화물 사이에는 냉각장치가 있어 냉각시키므로 고온으로부터 내화물과 철피를 보호하게 된다. 그러나 고로의 경년이 증가할 수록 내화물의 손상 및 마모가 진행되어 냉각 장치의 돌출이 많아지게 되어 냉각장치의 파손이 많아지며 철피의 적열 및 균열이 발생하여 조업 불안 요인이 된다. The main body structure is made of iron shell on the outside, and a high-strength refractory that can withstand high temperature heat and gas is built, and there is a cooling device between the refractory to cool, thereby protecting the refractory and iron shell from high temperature. However, as the aging of the blast furnace increases, the refractory damage and abrasion progresses, so that the protruding portion of the cooling system increases, so that the cooling system breaks, and the redness and cracking of the shell occur, which causes the operation instability.

촬영부(40)는 제2 지지부(30)의 단부에 결합되어 고로(C) 내부를 촬영하는 것으로서, 제2 지지부(30)가 제1 지지부(20)에 결합되어 회동함에 따라 촬영부(40)가 촬영하는 고로(C) 내부의 위치도 달라질 수 있다. 도 2는 본 발명의 일 실시예에 따른 고로 내벽 보수장치를 나타낸 도면이다. 도 2에 도시된 바와 같이, 본 발명에 따른 고로 내벽 보수장치의 제1 지지부(20) 및 제2 지지부(30)는 길이가 연장가능하도록 형성될 수 있다. 즉, 제1 지지부(20)와 제2 지지부(30)는 길이가 조절되어 연장되거나 축소될 수 있다.The imaging unit 40 is coupled to an end of the second support unit 30 to photograph the inside of the blast furnace C. The imaging unit 40 is rotated as the second support unit 30 is coupled to the first support unit 20 and rotates. ) Location inside the blast furnace (C) can also be different. 2 is a view showing the blast furnace inner wall repair apparatus according to an embodiment of the present invention. As shown in FIG. 2, the first support part 20 and the second support part 30 of the blast furnace inner wall repair apparatus according to the present invention may be formed to extend in length. That is, the length of the first support 20 and the second support 30 may be adjusted to extend or contract.
이때, 제1 지지부(20)는 텔레스코픽 연장부를 포함하여 길이가 조절된다. 즉, 안테나의 길이가 조절되는 것처럼, 복수개의 제1 지지부(20)를 구성하는 단위체가 존재하고, 하나의 단위체가 다른 단위체 내부로 삽입되어 이동하게 되면 제1 지지부(20)의 길이는 짧아지게 되고, 하나의 단위체가 다른 단위체 내부에서 빠져나오게 되면 제1 지지부(20)의 전체 길이가 길어지게 된다. At this time, the first support 20 includes a telescopic extension portion is adjusted in length. That is, as long as the length of the antenna is adjusted, there is a unit constituting the plurality of first support units 20, and if one unit is inserted into the other unit and moved, the length of the first support unit 20 is shortened. When one unit comes out of the other unit, the entire length of the first support unit 20 becomes long.
즉, 본체(10)에 결합된 제1 지지부(20)가 이동시 등에는 제1 지지부(20)의 길이가 짧을수록 유리할 수 있고, 이 경우, 단위체가 다른 단위체에 삽입됨으로써, 최대한으로 제1 지지부(20)의 길이를 줄일 수 있다. 한편, 제1 지지부(20)가 고로(C) 내부로 삽입되거나 삽입된 다음 고로(C) 내부의 일정 위치로 이동하기 위하여 제1 지지부(20)의 길이는 연장될 수 있다. That is, when the first support part 20 coupled to the main body 10 moves, the shorter the length of the first support part 20 is, the more advantageous it is. In this case, the first support part is inserted to the other unit body as much as possible, so that the first support part is maximized. 20 can be reduced in length. On the other hand, the length of the first support 20 may be extended so that the first support 20 is inserted into or inserted into the blast furnace (C) and then moved to a predetermined position inside the blast furnace (C).
제2 지지부(30)도 제1 지지부(20)와 마찬가지로 텔레스코픽 연장부를 포함하여 제2 지지부(30)의 전체 길이가 조절될 수 있다. 제2 지지부(30)도 길이가 조절됨으로써, 촬영부(40)가 고로(C) 내부의 노벽의 일정 위치를 촬영하는 것을 도울 수 있다. 즉, 제2 지지부(30)의 길이가 길어지게 되고, 제1 지지부(20)와 제2 지지부(30)의 각도가 90도에 가깝게 되면, 촬영부(40)가 고로(C) 내부의 노벽의 높은 부분까지 촬영할 수 있게 된다.Like the first support part 20, the second support part 30 may also have an overall length of the second support part 30 including a telescopic extension part. Since the length of the second support part 30 is also adjusted, it may help the photographing part 40 to photograph a predetermined position of the furnace wall inside the blast furnace (C). That is, when the length of the second support part 30 becomes long, and the angle between the first support part 20 and the second support part 30 approaches 90 degrees, the photographing part 40 is the furnace wall inside the blast furnace C. You can shoot up to the high part of the camera.

The blast furnace process charges coke as fuel and iron ore as raw materials through the charging hole in the upper part of the blast furnace, and blows coke to produce high heat and reducing gas by blowing high temperature hot air through a vent hole at the bottom of the blast furnace. Iron ore in the furnace is reduced-melted to produce molten iron and slag. At this time, the melt is discharged through the outlet of the bottom of the blast furnace.
이러한 고로는 외부가 철피로 되어 있고 내부에는 고온의 열과 가스에 견딜수 있도록 고강도 내화물이 축조되어 있고, 내화물에는 냉각장치가 삽입되어 내화물을 냉각시키므로 고온으로부터 내화물과 철피를 보호하게 된다. The blast furnace is made of an outer shell, and a high-strength refractory is built to withstand high temperature heat and gases, and a refrigeration device is inserted into the refractory to cool the refractory, thereby protecting the refractory and the shell from high temperatures.
그러나 고로의 경년이 증가할수록 내화물의 손상 및 마모가 진행되어 냉각 장치의 돌출이 많아지게 되어 냉각장치의 파손이 많아지며, 이에 따라 철피의 적열 및 균열이 발생하여 조업 불안 요인이 된다.However, as the aging of the blast furnace increases, damage and abrasion of the refractory proceeds, and the protrusion of the cooling device increases, thereby increasing the breakage of the cooling device. Accordingly, the redness and cracking of the steel bar are generated, resulting in unstable operation.

That is, when the first support part 200, the second support part 300, and the third support part 400 extend, the reel formed in the repair material supply part 110 is released to increase the length of the supply hose. When the length of the first support part 200, the second support part 300, and the third support part 400 is returned to its original state, the reel may be wound to reduce the length of the supply hose.
도 9에서와 같이, 제3 지지부(400)의 단부에는 분사노즐(500)이 회전가능하도록 결합되어 있다. 제3 지지부(400)에 접혀있던 분사노즐(500)은 제3 지지부(400)의 연장이 멈춘다음, 고로(C) 노벽으로 노벽 보수재를 분사할 수 있도록 노벽을 향하여 회전하게 된다.9, the injection nozzle 500 is rotatably coupled to an end of the third support part 400.

Will be able to spray.
즉, 본 발명의 다른 실시예에 따른 고로 노벽 보수장치는 제1 지지부(200)의 길이를 조절하여 고로(C) 내부로 삽입되는 길이를 조절하고, 제2 지지부(300)의 길이, 제3 지지부(400)의 길이 및 각 지지부 사이의 결합각도, 분사노즐(500)의 각도 및 회전정도를 조절하여 작업자가 원하는 위치에 노벽 보수재를 분사하여 고로(C) 노벽을 보수할 수 있게 된다.That is, the blast furnace furnace wall repair apparatus according to another embodiment of the present invention adjusts the length of the first support portion 200 to be inserted into the blast furnace (C), the length of the second support portion 300, the third By adjusting the length of the support unit 400 and the coupling angle between the support units, the angle and the degree of rotation of the injection nozzle 500, the operator can repair the blast furnace (C) furnace wall by spraying the furnace wall repair material at a desired position.
본 발명의 다른 실시예에 따른 발광부(800) 및 촬영부(900)는 분사노즐(500)에 결합되어 있지만 이에 한정되는 것은 아니고, 발광부(800) 또는 촬영부(900)는 제2 지지부(300) 또는 제3 지지부(400)에 결합되어도 동일한 작용 효과를 낼 수 있음은 자명하다.The light emitting unit 800 and the imaging unit 900 according to another embodiment of the present invention are coupled to the injection nozzle 500, but are not limited thereto. The light emitting unit 800 or the imaging unit 900 may be a second support unit. It is apparent that the same effect can be obtained even when the 300 is coupled to the third support 400.
