Description
본 발명은 용융아연 도금설비에 있어서 도금대상 강판 스트립의 도금조내부로의 인입을 안내하는 스나우트(Snout) 내부에서 발생하는 애쉬를 스나우트 외부로 배출 제거하기 위한 방법 및 장치에 관한 것으로, 특히 전자기장을 이용하며 도금공정진행중 스나우트 내부의 애쉬를 효과적으로 배출 제거할 수 있는, 전자기장을 이용한 용융 도금조의 스나우트내 애쉬 제거 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for discharging and removing ash generated inside a snout (Snout) for guiding the introduction of a steel sheet strip to be plated into a plating bath in a molten zinc plating apparatus. The present invention relates to a method and apparatus for removing ash in a snout of a hot dip bath using an electromagnetic field, which can effectively remove and remove ash in the snout during the plating process.
도1은 본 발명이 적용되는 용융아연 도금설비의 구성개요를 보여 주는데, 도금대상 강판(4) 스트립이 스나우트(1)를 통해 용융아연(2)이 수용되어 있는 도금조(7)내부로 인입되고, 이와 같이 도금조(7)내부로 인입되어 도금된 강판(4) 스트립은 싱크롤(9)을 거쳐 도금조(7)외부로 빠져 나간 다음 공정으로 진행되어 가게 된다. 이러한 용융아연 도금공정에 있어서, 상기 스나우트(1)의 내부는 고온상태로 용융아연(2)이 기화하기 쉬운 환경이다. 스나우트(1) 내부에서 기화한 아연은 스나우트(1) 내벽에 붙어 응고된 후 일부는 용융아연(2)위로 떨어지게 되는데, 이를 애쉬(Zn Ash)(3)라 한다. 상기 애쉬(3)는 용융아연(2)위에 떠있다가 도금과정에서 강판(4)의 표면에 부착됨으로써 도금 강판의 품질을 떨어뜨리는 요인으로 작용한다. 이와 같이 스나우트(1)내부에 발생 존재하는 애쉬(3)는 도금공정이 진행되는 동안에는 제거하기 곤란하므로 지속적으로 문제를 야기할 수 있다.Figure 1 shows the configuration of the hot-dip galvanizing equipment to which the present invention is applied, the strip of steel plate (4) to be plated into the plating bath (7) in which the molten zinc (2) is accommodated through the snout (1) The strip of steel sheet 4 drawn in and drawn into the plating bath 7 and thus plated is passed through the sink roll 9 to the outside of the plating bath 7 and then proceeds to the process. In such a hot dip galvanizing step, the inside of the snout 1 is an environment where the hot dip zinc 2 is easily vaporized in a high temperature state. Zinc vaporized in the snout (1) is solidified by attaching to the inner wall of the snout (1), and part of the zinc falls on the molten zinc (2), which is called an ash (Zn Ash) (3). The ash 3 floats on the molten zinc 2 and adheres to the surface of the steel sheet 4 in the plating process, thereby acting as a factor of degrading the quality of the coated steel sheet. As such, the ash 3 generated in the snout 1 may be difficult to remove during the plating process, and thus may continuously cause problems.
종래에는 상기 스나우트(1) 내부에 고압의 질소가스를 투입하여 발생하는 난류를 이용하거나 펌프를 이용하여 애쉬를 배출시키는 것 등의 방법을 사용하였으나, 애쉬 제거효율이 저급하고 장치가 복잡하기 때문에 실용화에 많은 어려움이 있었다.Conventionally, a method such as using turbulence generated by injecting high-pressure nitrogen gas into the snout 1 or discharging ash using a pump is used, but the ash removal efficiency is low and the apparatus is complicated. There have been many difficulties in practical use.
본 발명은 이러한 배경에서 연구된 것으로, 그 목적은 용융아연 도금공정에 있어서 상술한 바와 같이 스나우트 내부에서 발생하는 애쉬를 보다 효율적으로 배출 제거하여 도금품질을 높일 수 있는 새로운 애쉬 제거 방법 및 장치를 제공하고자 하는 것이다.The present invention has been studied in the background, the object of the present invention is to provide a new ash removal method and apparatus that can improve the plating quality by more efficiently discharged ash generated in the snout as described above in the hot dip galvanizing process It is to provide.

도2는 본 발명에 따른 스나우트내 애쉬 제거 장치의 도식적인 평면도.2 is a schematic plan view of an in-snap ash removal apparatus according to the present invention.

상기의 목적을 달성하기 위한 본 발명은 용융아연 도금설비의 도금조 스나우트 내부에 이동 자기장을 발생시킬 수 있는 수단을 스나우트 외부적소에 설치하여 스나우트 내부의 애쉬를 상기 수단에 의한 이동 자기장에 의해 스나우트 일측의 애쉬 배출구로 배출 제거하는 것을 특징으로 하는 전자기장을 이용한 용융도금조의 스나우트내 애쉬 제거 방법 및 장치를 제공한다.In order to achieve the above object, the present invention provides a means for generating a moving magnetic field in a plating bath snout of a hot dip galvanizing facility at an outside location of the snout so that the ash inside the snout is moved to the moving magnetic field by the means. The present invention provides a method and apparatus for removing ash in a snout of a molten plating tank using an electromagnetic field, wherein the ash discharge port is discharged to an ash outlet of one side of the snout.
이하에서, 이러한 본 발명을 첨부도면을 참조하여 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
도1, 도2에 도시된 바와 같이, 본 발명은 측면에 애쉬 배출구(6)를 형성한 스나우트(1)의 외부적소에 선형 유도 펌프(5)를 설치하고, 이 선형 유도 펌프(5)에 의해 스나우트(1)내부에 이동 자기장을 발생시켜 이 이동 자기장으로 스나우트(1) 내부의 애쉬(3)를 상기 애쉬 배출구(6)로 배출 제거하도록 하는 것이다. 바람직한 실시예에 있어서 상기 선형 유도 펌프(5)는 도2에 예시된 바와 같이 스나우트(1)의 양측면에 2대의 선형 유도 펌프(5)를 나누어 설치해 주도록 한다.As shown in Figs. 1 and 2, the present invention provides a linear induction pump 5 at an external location of a snout 1 having an ash outlet 6 formed on a side thereof. This causes the moving magnetic field to be generated inside the snout 1 so that the ash 3 inside the snout 1 is discharged to the ash outlet 6 by the moving magnetic field. In the preferred embodiment, the linear induction pump 5 is to be divided into two linear induction pump 5 on both sides of the snout 1 as illustrated in FIG.
이러한 본 발명의 스나우트(11)내 애쉬(3) 제거원리를 설명해 보면, 자장이 존재하는 영역에서 움직이는 도체의 내부에는 패러데이 법칙에 의해 전류가 유도된다. 반대로 도체가 정지해 있는 상태에서 자기장이 이동하는 경우에도 도체에 전류가 유도되며, 이때 전류의 방향은 자기장의 변화에 저항하는 방향으로 된다.Referring to the principle of removing the ash 3 in the snout 11 of the present invention, a current is induced by the Faraday law inside the conductor moving in the region where the magnetic field exists. On the contrary, even when the magnetic field moves while the conductor is stopped, current is induced in the conductor, and the direction of the current becomes a direction that resists the change in the magnetic field.
또한, 전류가 흐르는 도체에 자기장이 작용하면 상기 도체는 전류와 자기장에 각각 수직인 방향으로 힘을 받게 된다. 따라서, 상기와 같은 원리로부터 도체 주위에 자기장을 인가하고 그 자기장을 한 방향으로 이동시키면 자기장과 유도전류에 기인한 전자기력이 도체에 작용하여 자기장과 같은 방향으로 도체를 이동시킬 수가 있다.In addition, when a magnetic field is applied to a conductor through which current flows, the conductor is forced in a direction perpendicular to the current and the magnetic field, respectively. Therefore, if the magnetic field is applied around the conductor and the magnetic field is moved in one direction, the electromagnetic force due to the magnetic field and the induced current acts on the conductor, and the conductor can be moved in the same direction as the magnetic field.
본 발명은 이러한 전자기 원리를 이용하여 상기 용융아연 도금조(7)의 스나우트(1)내부에 존재하는 애쉬(3)를 스나우트(1)밖으로 효율적으로 배출 제거하도록 하는 것으로, 상기 스나우트(1)내부에 대한 이동 자기장 발생 수단으로서 일정한 크기를 갖고 일정한 속도로써 한 방향으로 이동하는 자기장을 발생시킬 수 있는 선형 유도 펌프(5)를 사용한다. 선형 유도 펌프(5)를 도2에 예시된 바와 같이 스나우트(1)의 앞뒤에 각각 설치하여 이동 자기장을 발생시키면 그 자기장이 액체 및 고체상태의 금속에 작용 됨으로써 스나우트(1)내의 용융아연(2)과 애쉬(3)가 애쉬 배출구(6)가 있는 쪽으로 이동하게 되며, 이와 같이 이동한 애쉬(3)를 애쉬 배출구(6)를 통해 스나우트(1)밖으로 배출 제거한다. 상기 스나우트(1)내부의 모서리부위에는 용융아연(2) 및 애쉬(3)의 애쉬 배출구(6)쪽으로의 이동을 용이하게 하기 위한 가이드(8)를 설치해 주도록 한다.The present invention is to efficiently discharge and remove the ash (3) present in the snout (1) of the hot-dip galvanizing bath (7) out of the snout (1) by using the electromagnetic principle, 1) As a moving magnetic field generating means for the inside, a linear induction pump 5 having a constant size and capable of generating a magnetic field moving in one direction at a constant speed is used. As shown in FIG. 2, linear induction pumps 5 are installed in front of and behind the snout 1 to generate a moving magnetic field. The magnetic field acts on the metal in the liquid and solid state, thereby melting zinc in the snout 1. (2) and the ash (3) is moved toward the ash outlet (6), the ash (3) moved in this way through the ash outlet (6) is discharged out of the snout (1). In the corner portion of the inside of the snout 1, a guide 8 for facilitating movement of the molten zinc 2 and the ash 3 toward the ash outlet 6 is provided.
[실시예]EXAMPLE
도1, 도2와 같이 구성된 용융아연 도금설비에 있어서, 도금조(7)의 크기를 800×400×200mm3로 하고, 스나우트(1)의 단면적은 500×100mm2로 하며, 선형 유도펌프(5)의 용량을 10KW로 하여, 이를 상용 주파수 60Hz로 구동시켜 애쉬 제거실험을 해 본 결과, 만족할만한 애쉬 제거 결과가 얻어졌다.In the hot-dip galvanizing facility configured as shown in Figs. 1 and 2, the size of the plating bath 7 is 800 × 400 × 200 mm 3 , the cross-sectional area of the snout 1 is 500 × 100 mm 2 , and the linear induction pump When the capacity of (5) was 10 KW and this was driven at a commercial frequency of 60 Hz, the ash removal experiment was conducted. As a result, satisfactory ash removal results were obtained.
따라서, 상술한 바와 같은 본 발명의 방법 및 장치를 이용할 경우 용융아연 도금공정에서 스나우트(1)내부에 발생 존재하게 되는 애쉬(3)를 공정이 진행되는 동안 매우 효과적으로 제거하여 도금품질을 가일층 높일 수 있는 효과가 얻어진다.Therefore, in the case of using the method and apparatus of the present invention as described above, the ash (3) generated in the snout (1) in the hot dip galvanizing process is very effectively removed during the process to further increase the plating quality. The effect can be obtained.
