Description
본 발명은 제철소에서 구비되는 용융아연도금욕조의 침전 이물질 제거장치에 관한 것으로서, 더욱 상세하게는 용융아연도금욕조의 바닥에 침전된 각종 이물질을 버킷으로 포집하여 간편하게 자동제거할 수 있도록 한 용융아연도금욕조의 침전이물질 제거장치에 관한 것이다.The present invention relates to an apparatus for removing sediment foreign matter from a hot dip galvanizing bath provided in a steel mill, and more specifically, hot dip galvanized to easily remove automatically by collecting various foreign substances deposited on the bottom of the hot dip galvanizing bath with a bucket. The present invention relates to a device for removing sediment foreign matter from a bathtub.
일반적으로 제철소에 설치된 냉연공장의 연속용융아연도금공정은 도1에 나타난 바와 같이, 풀림(annealing) 처리된 강판(900)을 아연도금욕조(500)의 용융아연용액(510)을 통과시켜서 강판(900)의 표면에 아연을 도금하게된다.In general, the continuous molten zinc plating process of the cold rolling mill installed in the steel mill is passed through the molten zinc solution (510) of the galvanizing bath 500, as shown in Figure 1, the annealing (steel plate 900) 900) to the surface of zinc.
이때 강판(900)은 강판가이드를 안내 받으면서 용융아연도금욕조(500)를 통과하고 싱크롤(700)을 거치면서 도금된 후 에어나이프(800) 사이를 통과하게 된다.At this time, the steel sheet 900 is passed through the hot dip galvanizing bath 500 while being guided through the steel plate guide and plated while passing through the sink roll 700 to pass between the air knife 800.
동 공정에서 에어나이프(800)는 길고 좁은 틈새를 빠져 나오는 고속의 공기가 강판(900)에 묻은 용융아연(510)의 두께를 조절하는 기능으로 작동시 심한 소음이 발생된다.In the same process, the air knife 800 is a function of controlling the thickness of the molten zinc 510 in which the high-speed air exiting the long and narrow gaps in the steel sheet 900 generates severe noise during operation.
이와 같은 과정을 통하여 강판(900)이 아연도금욕조(500)내를 통과하면서 강판(900)의 표면에 부착되어 있는 미세한 철분이 용융아연(510)과 반응하여 용융아연보다 무거운 화합물을 형성하여 아연도금욕조(500)의 바닥에 침전되고, 이와 같이 침전된 아연화합물을 침전이물질(600)라 하며, 동 침전이물질(600)중 일부는 강판(900)이 고속으로 진행할 때 부유하여 강판(900)의 표면에 묻어 도금 강판의 품질을 저하시키는 요인이되고, 또한 아연도금욕조내의 도금용액을 관리하는데 좋지않은 영향을 미치기 때문에 정기적으로 침전이물질(600)를 제거하게 된다.Through this process, while the steel sheet 900 passes through the galvanizing bath 500, the fine iron adhering to the surface of the steel sheet 900 reacts with the molten zinc 510 to form a compound that is heavier than the molten zinc zinc. The zinc compound precipitated at the bottom of the plating bath 500 and thus precipitated is called precipitated foreign matter 600, and some of the precipitated foreign matter 600 is suspended when the steel sheet 900 proceeds at high speed. It is a factor that reduces the quality of the plated steel plate buried in the surface of the, and also has a bad effect on managing the plating solution in the galvanizing bath to remove the precipitate foreign matter 600 regularly.
종래에 사용하여오던 침전이물질 제거 방법은 400~500℃에 이르는 고온 용융아연용액(510)을 용융아연도금욕조(500)에서 바깥으로 퍼 내어 다른 용기에 옮기고, 용융아연도금욕조의 바닥에 가라 앉아 있는 침전이물질(600)를 수작업으로 제거한 후 바깥의 용기에 옮겨둔 용융아연용액을 용융아연도금욕조(500)에 다시 옮겨 적정온도로 가열하여 사용하게 된다.In the conventional method of removing the settled foreign matter, the hot molten zinc solution 510 ranging from 400 to 500 ° C is scooped out from the hot dip galvanizing bath 500 and transferred to another container, and then sinks to the bottom of the hot dip galvanizing bath. After manually removing the precipitated foreign matter 600, the molten zinc solution transferred to the outer container is transferred back to the molten zinc plating bath 500 to be heated to an appropriate temperature.
이와 같은 종래의 방법은 고온의 용융아연용액(510)을 용융아연도금욕조에서 다른 용기로 옮겨 가는데 시간이 많이 소요되고, 또 용융아연용액(510)의 손실이많고 고온이어서 안전사고의 위험이 높아서 이에 대한 획기적인 개선이 절실히 요구되고 있다.Such a conventional method takes a long time to transfer the hot molten zinc solution 510 from the hot dip galvanizing bath to another container, and the loss of the hot dip zinc solution 510 is high and high temperature, so the risk of safety accident is high. There is an urgent need for significant improvements.
이에 본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로서, 개폐가 가능한 버킷을 열린 상태로 자중에 의하여 침전이물질이 위치한 용융아연도금욕조의 바닥까지 하강시킨후 버킷을 닫으면 버킷 내부에 침전이물질이 포집되고, 이를상승시키면 버킷에 뚫린 미세한 구멍을 통하여 용융아연용액은 배출되고 입자가 큰 침전이물질만 담겨지므로 동 버킷을 아연도금욕조 위로 상승시킨후 용융아연용액을 제거하고, 침전이물질만 외부로 제거할 수 있는 장치를 제공하고 이를 자동으로 작동할수 있도록하여 침전이물질을 안전하고 효과적으로 제거함에 목적이있다.Accordingly, the present invention has been invented to solve the above problems, the bucket is opened and closed to lower the bottom of the molten zinc plating bath in which sedimented foreign matter is located by its own weight, and then close the bucket, sedimented foreign matter is collected inside the bucket. If it is raised, the molten zinc solution is discharged through the minute hole drilled in the bucket, and only the precipitated particles with large particles are contained. Therefore, the bucket is raised above the galvanizing bath to remove the molten zinc solution. It aims to provide safe and effective removal of sedimentary debris by providing a device that can be used and automatically operating it.

본 발명은 도2와 같이 용융아연도금욕조의 상부에 용융아연도금욕조의 길이 방향과 폭 방향으로 버킷을 이동시킬수 있는 이동유니트와, 동 유니트 상부에 구비된 버킷을 와이어 로프에 의하여 승.하강시킬수 있도록 한 승강 유니트와, 상기 와이어로프로 버킷을 개폐하는 버킷 개폐유니트와, 침전이물질을 제거하기 위한 버킷의 수동조작 및 자동운전으로 조작하는 제어시스템으로 구성 된다.According to the present invention, a moving unit capable of moving the bucket in the longitudinal direction and the width direction of the hot-dip galvanizing bath in the upper part of the hot-dip galvanizing bath as shown in FIG. The lifting unit, the bucket opening and closing unit for opening and closing the bucket with the wire rope, and the control system for operating by manual operation and automatic operation of the bucket to remove the sediment foreign matter.
이와 같은 본발명의 침전이물질 제거장치를 제철소에 구비되는 용융아연도금욕조에 설치하여 침전이물질의 제거과정을 상세하게 설명하면 다음과 같다.When the precipitation foreign matter removal apparatus of the present invention is installed in a molten zinc plating bath provided in a steel mill, the removal process of the precipitate foreign matter is described in detail as follows.
도2 및 도3과 같이 제어시스템(90)중 주행,횡행제어부(91)의 제어에 의해 주행모타(15)를 구동시켜 용융아연도금욕조에서 길이방향의 원하는 위치에 버킷(80)을 이동시킨 후 다시 횡행모타(25)를 구동시켜 아연도금욕조에서 폭방향의 원하는 위치에 버킷(80)을 이동시키고, 승하강제어부(92)의 제어에 의해 도4와 같이 실린더(55)를 작동시키면 도5와 같이 버킷(80) 상부의 실린더로드(56)가 전진하여 버킷고정링크(73)를 축으로 하여 버킷(80)을 구성하는 좌측버킷(75)과 우측버킷(76)의 측방버킷고정링크(71) 보다 하강하게 되고 버킷은 열리게 된다.2 and 3, the driving motor 15 is driven under the control of the traveling and transverse control unit 91 in the control system 90 to move the bucket 80 to a desired position in the longitudinal direction in the hot dip galvanizing bath. After driving the transverse motor 25 again, the bucket 80 is moved to a desired position in the width direction in the galvanizing bath, and the cylinder 55 is operated as shown in FIG. 4 under the control of the elevating control unit 92. As shown in FIG. 5, the cylinder rod 56 in the upper portion of the bucket 80 is advanced to the side bucket fixing link of the left bucket 75 and the right bucket 76 constituting the bucket 80 with the bucket fixing link 73 as an axis. It becomes lower than 71 and the bucket is opened.
이때 도2의 제어시스템(90)의 하중제어부(93)의 제어에 의해 도3과 같이 로드셀(40)에서 감지된 중량을 기억시켜 승하강제어부(92)의 제어에 의해 승하강모타(35)가 구동되어 드럼(36)을 회전시키면 와이어로프(30)가 풀리게 되고, 도2와 같이 버킷개폐유니트(50)와 버킷(80)이 하강하고, 도5와 같이 좌측버킷(75)과 우측버킷(76)이 용융아연용액 속을 통과하여 침전이물질에 도달하게 된다.At this time, by the control of the load control unit 93 of the control system 90 of FIG. 2 stores the weight sensed by the load cell 40 as shown in FIG. 3 and the lifting motor 35 by the control of the lifting control unit 92 When the drum 36 is rotated to loosen the wire rope 30, the bucket opening / closing unit 50 and the bucket 80 descend as shown in FIG. 2, and the left bucket 75 and the right bucket as shown in FIG. 5. (76) passes through the molten zinc solution and the precipitate reaches foreign matter.
또 도5와 같이 하중제어부(93)에서 초기의 로드셀(40) 값보다 측정된 로드셀(40)의 값이 설정치보다 작으면 좌측버킷(75)과 우측버킷(76)이 침전이물질에 도달하여 와이어로프(30)가 느슨해 지는 것을 의미하므로 도3과 같이 승하강모타(35)를 정지시키고, 도4의 실린더(55)를 후퇴시키면 실린더로드(56)가 후퇴하면서 도5의버킷고정링크(73)를 축으로 좌측버킷(75)과 우측버킷(76)이 닫히게 되고, 침전이물질과 용융아연용액이 버킷(80)내에 포집된다.In addition, when the value of the load cell 40 measured by the load control unit 93 than the initial load cell 40 value is smaller than the set value as shown in FIG. 5, the left bucket 75 and the right bucket 76 reach the settled foreign matter and wire. Since the rope 30 is loosened, the lifting and lowering motor 35 is stopped as shown in FIG. 3, and when the cylinder 55 of FIG. 4 is retracted, the cylinder rod 56 is retracted and the bucket fixing link 73 of FIG. 5 is retracted. ), The left bucket 75 and the right bucket 76 are closed, and the precipitated foreign matter and the molten zinc solution are collected in the bucket 80.
또 승하강모타(35)를 역전 구동하여 버킷개폐유니트(50)와 버킷유니트를 위로 올리면 버킷(80)에 포집된 용융아연용액은 용융아연배출구멍(77)을 통해 바깥으로 빠져 나오고 입자가 큰 침전이물질만 버킷(80) 내부에 잔존 된다.In addition, when the lifting and lowering motor 35 is driven in reverse, the bucket opening and closing unit 50 and the bucket unit are lifted up, and the molten zinc solution collected in the bucket 80 comes out through the molten zinc discharge hole 77 and has large particles. Only sedimentary foreign matter remains in the bucket 80.
이와 같이 침전이물질을 버킷(80)에 포집하여 버킷개폐유니트(50)가 상승하여 도4와 같이 버킷개폐유니트(50)에 구비되고 리미트스위치(60)가 상부 프레임에 접촉하면 승하강모타(35)가 정지되고, 주행모타(15)와 횡행모타(25)를 작동하여 이물질수납박스 지점으로 버킷(80)이 이동되며 도4와 같이 실린더(55)를 전진하면 실린더로드(56)가 전진하여 버킷고정링크(73)를 축으로 하여 좌측버킷(75)과 우측버킷(76)이 열리면서 버킷(80)의 내부에 담겨진 침전이물질을 이물질 수납박스로 낙하하게 되는 것이다.Thus, the foreign matter is collected in the bucket 80, the bucket opening and closing unit 50 is raised to the bucket opening and closing unit 50 as shown in Figure 4 and the limit switch 60 is in contact with the upper frame lift motor 35 ) Is stopped, the driving motor 15 and the transverse motor 25 are operated to move the bucket 80 to the foreign matter storage box point, and when the cylinder 55 is advanced as shown in FIG. 4, the cylinder rod 56 is advanced. With the bucket fixing link 73 as an axis, the left bucket 75 and the right bucket 76 are opened to drop the settled foreign matter contained in the bucket 80 into the foreign matter storage box.
또 본 발명은 도4와 같이 승강프레임(51)의 상부에 설치된 전동 바이브레타(57)은 침전이물질을 담은 버킷(80)에서 침전이물질을 비울때 진동을 가하여 버킷(80)에서 침전이물질의 분리를 촉진하게 된다.In addition, according to the present invention, the electric vibrator 57 installed on the lifting frame 51 as shown in FIG. 4 separates the sedimented foreign matter from the bucket 80 by applying vibration when emptying the sedimented foreign matter from the bucket 80 containing the sedimented foreign matter. Will promote.
또 본 발명은 버킷(80)에 용융아연배출구멍(77)이 형성되어 침전이물질을 버킷(80)으로 포집하면 용융아연용액은 용융아연배출구멍(77)으로 흘러나오게 된다.In the present invention, when the molten zinc discharge hole 77 is formed in the bucket 80 to collect the foreign matter precipitated in the bucket 80, the molten zinc solution flows out into the molten zinc discharge hole 77.

이와 같이 본 발명은 전후와 폭방향으로 이동되는 유니트와 동 유니트에 버킷을 설치하여 용융아연도금욕조의 바닥에 침전된 침전이물질을 버킷으로 포집하고 버킷에 모아진 침전이물질과 용융아연용액에서 용융아연용액은 버킷의 미세한 구멍을 통하여 배출되고, 버킷에는 침전이물질만을 포집하고, 이를 외부로 배출시키게 되므로 침전이물질의 제거작업을 간편하게 수행할 수 있게 된다.As described above, the present invention collects the deposit foreign matter precipitated at the bottom of the hot dip galvanizing bath with the bucket by installing a bucket in the unit and the same unit that is moved in the front and rear and width directions, and then collect the precipitated foreign matter and the zinc zinc solution in the molten zinc solution. The silver is discharged through the minute hole of the bucket, the sediment is collected only in the bucket, and discharged to the outside it is possible to easily perform the removal of the deposit foreign matter.
또한 본 발명은 용융아연용액과 침전이물질의 비중 및 입도차이를 이용하여 용융아연도금욕조내에서 침전이물질만을 포집하여 제거하도록 함으로서 용융아연용액이 외부로 배출되는 것을 예방할 수 있게 된다.In addition, the present invention can prevent the molten zinc solution from being discharged to the outside by collecting and removing only the precipitated foreign matter in the molten zinc plating bath by using the difference in specific gravity and particle size of the molten zinc solution and precipitated foreign matter.
또 본 발명은 도7과 같은 제어흐름도에 설정하게 되면 일연의 과정을 자동공정으로 수행할 수 있게 된다.In addition, when the present invention is set to the control flow chart as shown in Figure 7, it is possible to perform a series of automatic processes.
따라서 이상과 같은 본 발명은 제철소에서 강판을 용융아연도금욕조에 통과시켜 강판에 아연도금을 하여 생산하는 공정에서 용융아연도금욕조에 침전되는 이물질을 버킷을 이용하여 효과적으로 포집하여 제거할수 있게 되므로서 강판의 품질을 높일수 있고, 용융아연도금욕조내의 침전이물질을 안전하고 효율적으로 제거할 수 있는 특징이 있다.Therefore, the present invention as described above can effectively collect and remove foreign substances precipitated in the hot dip galvanizing bath by using a bucket in the process of producing the galvanized steel sheet by passing the steel sheet through a hot dip galvanizing bath in a steel mill. It is possible to improve the quality of and to remove the foreign matter precipitated in the hot dip galvanizing bath safely and efficiently.
