본 고안은 냉각반 장치에 관한 것으로, 특히 용광로 노체 철피를 보호하기 위하여 설치된 순동체 수평형복식구조 냉각반 장치에 관한 것이다.The present invention relates to a cooling panel apparatus, and more particularly, to a pure-body horizontal type double structure cooling panel apparatus installed to protect a furnace furnace shell.
종래 고로에서의 냉각반은 풍구부에서부터 축상부에 걸쳐 수평으로 삽입되어서 철피의 열부하 방지를 위해 사용되고 있으나 조업의 경과에 따라 노벽연와는 필연적으로 마모되고 아울러 냉각반 용손도 발생하게 되었다. 게다가, 고로조업중 냉각반이 용손되면 일단 냉각수 공급을 차단하고 냉각반 맹봉(盲棒)으로 노내의 가스(GAS)등 내용물의 유출을 방지하기 위하여 맹조치 시키고 차기 정기수리 작업시 교체 작업을 실시하게 되는데 이때 냉각반 선단부의 휨발생이나 용해되어 선단면에 턱이 발생하여 잘 취외되지 않는다. 이와 같이 되면 외부에서 지렛대나 해머타격으로 물리적인 충격을 가하게 된다.Conventionally, the cooling plate in the blast furnace is used to prevent the heat load of the iron shell is inserted horizontally from the air bulge to the shaft portion, but as the progress of the operation inevitably wear the furnace wall smoke and also caused the cooling plate melting. In addition, once the cooling panel is damaged during the blast furnace operation, the cooling water supply is shut off and the cooling panel blind rod is used to prevent leakage of the gas (GAS) in the furnace and to be replaced during the next regular repair work. At this time, the occurrence of bending or melting of the tip end of the cooling plate causes jaw on the end surface and is not easily removed. This will cause a physical impact from the lever or hammer strike from the outside.
상기와 같이 취외하면 제 7 도의 참고번호 11과 같이 상부연와가 탈락되어 철피의 적열이나 균열을 유발하여 노의 수평을 단축시키는 직접적인 동기가 되며 정비작업 또한 증가하게 된다.Withdrawal as described above, as shown by reference numeral 11 of FIG. 7, the upper edge is dropped, which causes direct heating or cracking of the steel bar, which is a direct motive for shortening the level of the furnace, and also increases maintenance work.
본 고안은 상기와 같은 종래의 단점을 극복하기 위하여 고안된 것으로 냉각반 선단부에서의 용손(냉각반 용손은 선단부에서 발생이 전체의 98%차지)이 1회 발생되어도 교환작업을 실시하지 않고 냉각반이 삽입된 채로 재사용할 수 있게 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to overcome the above-mentioned drawbacks. Even if the melting loss (cooling plate melting loss is 98% of the total amount generated at the distal end) occurs at the front end of the cooling panel, the cooling panel is not performed without replacement. It can be reused while being inserted and described in detail by the accompanying drawings as follows.
본 고안은 제 1 도와 같이 4경로형태(path type)의 냉각반으로 냉각수 유로(流路) 형성을 복식구조로 제 3 도와 같이 설치하였으며 제 4 도 (4')부의 (C,D,E,F)급, 배수구를 각각 2개씩 4개로 하고 연결용 플렌지 니플을 제 2 도의 냉각반에 (3,4,5,6)과 같이 설치한다.The present invention is a four-path type cooling panel like the first diagram, and the cooling water flow path is formed in a double structure with the third diagram, and the (C, D, E, F) Class 2 drains and 4 drains each are installed, and the connecting flange nipple is installed in the cooling panel of Fig. 2 as (3, 4, 5, 6).
본 고안은 냉각반을 복식으로 사용하기 위하여 1차 급수라인(7(을 니플(3)로 연결하여 노내부 냉각반 선단부(1)에 냉각시켜 선단의 냉각효유을 향시키고 니플(6)로 배수된 물이 연결용 단관(9)을 거쳐서 니플(5)을 통과하여 냉각반 내부에 2차로 급수시켜서 최종배수를 니플(4)과 라인(8)을 통하여 배수하게 한다. 상기와 같이 되므로 냉각반이 용손되면 냉각반 급배수라인을 3단 1연(냉각반 3개가 1개연으로 연결하여 급수 메인에서 하부 냉각반 1단에 냉각시키고 다시 냉각반 2단을 거쳐 냉각반 3단을 냉각시킨 후 배수됨을 말하며 고로에서의 냉각반은 2단 1연, 3단 1연, 5단 1연으로 설치되어 제일 많이 설치된 것은 제 5a 및 제 5b 도와 같이 3단 1연 시트템으로 되어 있다.) 중 3단이 용손되었을 시를 나타낸 것으로서 제 5a 도에서 냉각반 급수관주밸브(17)를 폐쇄시킨 후 냉각반 2단에서 냉각반 3단 급수용 연결관(G)를 취외하고 다시 니플(5,6)에 연결용 단관(9)을 해체하여 취외한다.The present invention is connected to the primary water supply line 7 (to the nipple (3) to cool the end of the furnace cooling panel front end (1) in order to use the cooling panel in multiples to direct the cooling oil of the tip and drained to the nipple (6) The water is passed through the nipples 5 through the connecting pipes 9 to supply the secondary water to the inside of the cooling panel so that the final drainage is drained through the nipples 4 and line 8. If it is damaged, the cooling tank supply / drain line is connected to three stages of one stage (three cooling stages are connected to one edge) to cool the first stage of the lower cooling stage from the water supply main, and then to cool the three stages of cooling stage through the two cooling stages. In the blast furnace, the cooling panel is installed in 2 stages 1 station, 3 stages 1 station, and 5 stages 1 station, and the most installed one consists of 3 stages 1 station system like 5a and 5b. When the cooling water supply line main valve 17 is closed in FIG. After turning on, remove the cooling pipe three-stage water supply pipe (G) from the second stage of the cooling panel, and then disassemble and connect the end pipe (9) to the nipples (5, 6) again.
그런 후, 제 6 도의 냉각반 맹봉(10)을 니플(3,6)에 맹조치 시키로 제 5a 도의 냉각반 2단급수용 연결관(G)을 니플(5)에 연결하여 냉각반 내부를 취외하지 않고 냉각반이 1회 용손되어도 재사용할 수 있게 한 것이다.Then, the cooling plate blind rod 10 of FIG. 6 is brought into contact with the nipples 3 and 6, and the cooling panel two-stage water supply pipe G of FIG. 5A is connected to the nipple 5 to take out the inside of the cooling panel. Instead, the cooling panel can be reused even if it is damaged once.
이상과 같이 설치한 냉각반의 효과를 설명하면 다음과 같다.The effect of the cooling board installed as above is as follows.
냉각반이 용손되었을시 냉각반맹봉(10)을 제 6 도 니플(3,6)에 설치하므로 냉각반이 1회 용손되어도 취외하지 않고 재사용할 수 있으며 냉각반 길이도 최추 길이 800πm에서 노벽연와 잔존을 고려 450~650πm로 축소여 삽입하고 있으나 본 고안은 냉각반 총길이를 800πm로 단식 냉각반과 동일하게 하고 내부 냉각반의 길이를 450~650πm로 설치되어 있어 냉각반 길이를 조절할 필요도 없을뿐더러 또한 냉각반을 취외하지 않으므로 냉각반 취외로 인한 제 7 도의 잔존연와(11)의 붕괴방지로 고로철피(13)의 적열 및 균열을 예방할 수 있어서 안전된 고로조업과 노수명연장에 크게 기여하는 유용한 고안이다.When the cooling plate is damaged, the cooling bleaching rod 10 is installed in the sixth nipple (3, 6), so that the cooling plate can be reused without taking out even if the cooling plate is melted once, and the length of the cooling plate remains at the bottom length of 800πm. In consideration of this, the present invention is reduced and inserted into 450 ~ 650πm, but the design of the present invention is the same as the single cooling panel with the total length of the cooling panel to 800πm, and the length of the internal cooling panel is 450 ~ 650πm. Since it prevents the collapse and cracking of the blast furnace shell 13 by preventing the collapse of the remaining edge 11 of FIG.
