Description
본 발명은 용융아연 도금설비의 개선에 관한 것으로, 특히 직류자장을 이용한 강판 진동방지 장치를 구비하는 용융아연 도금설비에 관한 것이다.The present invention relates to an improvement of a hot dip galvanizing installation, and more particularly, to a hot dip galvanizing installation having a steel plate vibration preventing device using a direct current magnetic field.
강판에 용융아연을 도금하는 공정에서, 아연 도금조를 통과하여 나온 철판은 에어나이프에서 아연 도금층의 두께를 조절하고 가열대와, 유지대, 냉각대를 거쳐 턴어라운드롤을 지나게 된다. 이때, 도금조와 턴어라운드롤까지의 거리가 약 45m 이상이 되기때문에 강판의 진동으로 인한 도금량 편차가 발생하여 불량을 유발하게 된다. 이에 본 발명은 도금조와 턴어라운드롤의 중앙부에 직류 전자석을 포함하는 진동방지장치를 설치하여 강판 진동을 방지하고, 또 가이드 에어노즐로 냉각능을 높여 도금품질을 높일 수 있도록 개선된 용융아연 도금설비를 제공하는 것을 목적으로 한다.In the process of plating hot-dip zinc on the steel sheet, the iron plate passed through the galvanizing bath controls the thickness of the zinc plating layer in the air knife and passes through a turnaround roll through a heating table, a holding table, and a cooling table. At this time, since the distance between the plating bath and the turnaround roll is about 45 m or more, a plating amount variation occurs due to vibration of the steel sheet, which causes a defect. Accordingly, the present invention provides an improved molten zinc plating apparatus to prevent vibration of the steel sheet by installing a vibration preventing device including a direct current electromagnet at the center of the plating bath and the turnaround roll, and to improve the plating quality by increasing the cooling capacity with a guide air nozzle. It aims to provide.
일반적으로 용융아연도금 강판은 도장성, 용접성 및 도장후 내식성이 우수하여 자동차용 강판으로 널리 사용되고 있다. 연속용융아연도금 공정중에서, 아연욕조를 통과한 도금된 강판은 에어나이프로 미응고 용융아연이 제거된 후 가열대와 유지대에서 아연도금층이 완전히 굳기 전에 아연과 철의 계면 열확산 반응으로 합금층을 생성시키고, 냉각내에서 냉각한 후 턴어라운드롤을 지나게 된다. 그러나, 용융아연 도금조에서 턴어라운드롤까지는 그 거리가 45m 이상이 되고 에어나이프에서 고압의 공기를 분출하기 때문에 강판에 진동현상이 발생하여 도금층의 두께가 불균일해지는 문제점이 있게 된다. 가열대와 유지대를 통과한 강판의 온도는 450-550℃ 정도를 유지하게 되고 냉각대에서 150-250℃로 냉각되나, 강판의 진동으로 인해 도금층이 두꺼워진 경우는 냉각이 늦어지기 때문에 턴어라운드롤에서 고온의 합금층이 흡착 탈락하는 현상이 발생하게 된다. 이러한 문제를 해결하기 위하여 공기를 불어넣어 냉각시키는 공기냉각법, 강판 표면에 냉각수를 분무시켜 냉각시키는 방법, 냉각롤을 이용하여 냉각시키는 방법 등이 개발되었으나, 공기냉각법은 설비상 제한으로 냉각능이 부족하고, 냉각수를 분무할 경우는 냉각능은 충분하나 냉각수에 의한 도금층의 고온산화 및 턴어라운드롤 통과시 미끄럼 현상이 발생하는 문제점이 있다. 냉각롤을 이용하는 방법은 냉각롤의 회전 속도와 강판의 속도가 다를 경우 상대적으로 슬립이 일어나 도금층에 결함이 발생하는 문제점이 있다.In general, hot dip galvanized steel sheet is widely used as a steel sheet for automobiles because of excellent paintability, weldability and corrosion resistance after painting. In the continuous hot dip galvanizing process, the plated steel sheet which passed through the zinc bath is formed by an interfacial thermal diffusion reaction between zinc and iron after the non-solidified molten zinc is removed with air knife and before the zinc plating layer is completely hardened in the heating and holding zones. After cooling in cooling, it is passed through a turnaround roll. However, since the distance from the hot dip galvanizing tank to the turnaround roll is 45 m or more and the high pressure air is ejected from the air knife, a vibration phenomenon occurs in the steel sheet and the thickness of the plating layer becomes uneven. The temperature of the steel plate passed through the heating table and the holding table is maintained at about 450-550 ℃ and is cooled to 150-250 ℃ in the cooling table, but when the plated layer thickened due to the vibration of the steel sheet, the cooling is delayed in the turnaround roll The phenomenon that the high-temperature alloy layer is adsorbed and dropped off occurs. In order to solve this problem, the air cooling method of blowing air to cool, the cooling method by spraying cooling water on the surface of the steel sheet, the cooling method using a cooling roll, etc. have been developed. When spraying the cooling water, the cooling capacity is sufficient, but there is a problem that the sliding phenomenon occurs when the high temperature oxidation and turnaround rolls pass through the plating layer by the cooling water. The method using the cooling roll has a problem that a slip occurs in the plated layer due to slip when the rotational speed of the cooling roll and the speed of the steel sheet are different.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위해 연구개발된 것으로, 그 목적은 용융아연 도금설비의 유지대와 냉각대 사이에 직류 전자석을 이용한 강판 진동방지장치를 설치하여 강판의 진동에 의한 도금량 편차를 줄이고, 가이드 에어노즐을 통한 냉각능 향상으로 더욱 우수한 품질의 용융아연도금 강판을 제조해낼 수 있는 용융아연 도금설비를 제공하고자 하는 것이다.The present invention has been researched and developed in order to solve the problems of the prior art as described above, the object of which is to install a vibration damping device of the steel sheet using a direct current electromagnet between the holding and cooling of the hot-dip galvanizing equipment by the vibration of the steel sheet The purpose of the present invention is to provide a hot-dip galvanizing facility capable of manufacturing a hot-dip galvanized steel sheet of higher quality by reducing plating variation and improving cooling performance through a guide air nozzle.

이하에서, 상기의 목적을 달성하기 위한 본 발명을 첨부도면을 참조하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention for achieving the above object will be described in more detail.
먼저, 도 1을 참조하여 본 발명의 구성개요를 설명한다. 예열된 강판(1)은 스나우트(2)를 통하여 도금조(3)내로 들어와서 씽크롤(4)과 스테빌라이징롤(5)을 거쳐 도금조(3) 밖으로 나가게 된다. 이 강판(1)은 에어나이프(6)를 통과하면서 적절한 에어의 세기로 강판 표면상의 과량의 용융아연을 제거하여 필요한 두께로 도금되어 가열대(7)와 유지대(8)에서 합금화된다. 합금화된 강판은 냉각대(9)와 턴어라운드롤(10)을 거쳐 다음 공정으로 빠져 나간다. 이와 같이 도금조(3) 밖을 나온 강판(1)은 진동하기 시작하여 유지대(8)와 냉각대(9)의 중간위치, 즉 도금조 상부 20-25m상의 부분에서 그 진동폭이 최대로 된다. 이 위치에 냉각을 겸한 가이드 에어노즐(14)과 직류 전자석(18)을 포함하는 강판 진동방지장치(11)를 설치하여 강판(1)의 진동을 억제하는 장치를 설치구비하는 것이 본 발명에 따른 용융아연 도금설비의 기술적 구성요지이다.First, with reference to Figure 1 will be described the configuration of the present invention. The preheated steel sheet 1 enters the plating bath 3 through the snout 2 and exits the plating bath 3 via the sink 4 and the stabilizing roll 5. The steel sheet 1 is plated to the required thickness by removing excess molten zinc on the surface of the steel sheet with an appropriate air strength while passing through the air knife 6 and alloyed in the heating table 7 and the holding table 8. The alloyed steel sheet passes through the cooling stage 9 and the turnaround roll 10 to the next process. Thus, the steel plate 1 which exited out of the plating tank 3 starts to vibrate, and the vibration width becomes the maximum in the intermediate position of the holding stand 8 and the cooling stand 9, ie, 20-25 m on the upper part of the plating tank. . According to the present invention, there is provided a device for suppressing vibration of the steel sheet 1 by installing a steel plate vibration preventing device 11 including a guide air nozzle 14 and a direct current electromagnet 18, both of which serve as cooling. Technical composition of hot dip galvanizing equipment.
본 발명의 구성요부의 구성 및 작동원리를 도 2를 참조하여 설명한다. 강판 진동이 최대가 되는 지점에 전자석(18)의 자극(12)이 오도록 설치한다. 전자석(18)의 자극(12)간 간격(13)은 조절가능하도록 만든다. 강판(1)이 진동할 때 자장을 인가하면 강판(1)은 강자성체이기 때문에 자극(12)쪽으로 이동하게 되며 진동은 감소하게 된다. 그러나, 강판(1)에 걸리는 인장력이 작아 느슨해지면 강판(1)이 자극(12)에 붙게 되어 강판(1)표면과 자극(12)의 마찰에 의해 강판(1)에 흠이 발생하게 된다.The configuration and operation principle of the components of the present invention will be described with reference to FIG. The magnetic pole 12 of the electromagnet 18 is provided at the point where the steel plate vibration is maximized. The spacing 13 between the magnetic poles 12 of the electromagnet 18 is adjustable. If the magnetic field is applied when the steel sheet 1 vibrates, the steel sheet 1 is moved to the magnetic pole 12 because the steel sheet 1 is a ferromagnetic material, and the vibration is reduced. However, when the tensile force applied to the steel sheet 1 becomes small and loosens, the steel sheet 1 adheres to the magnetic pole 12, and the steel sheet 1 is damaged by friction between the surface of the steel sheet 1 and the magnetic pole 12.
이러한 문제를 보완하기 위하여 강판(1)에 에어를 분사할 수 있는 에어노즐(14)을 자극(12)과 자극(12)사이에 설치하고, 이를 통해 에어를 분사하여 강판(1)이 자극(12)에 붙는 것을 방지함과 동시에 강판(1)을 냉각할 수 있도록 한다. 상기 가이드 에어노즐(14)은 기존의 냉각롤과는 달리 회전하지 않기 때문에 동기 회전시킬 필요가 없게 되어 종래와 같은 냉각롤에 의한 결함 발생의 문제를 해소할 수 있다.In order to compensate for this problem, an air nozzle 14 capable of injecting air to the steel sheet 1 is installed between the magnetic pole 12 and the magnetic pole 12, and the air is sprayed through the steel sheet 1 to stimulate the magnetic pole ( 12) It is possible to cool the steel sheet (1) while preventing sticking to it. Since the guide air nozzle 14 does not rotate unlike the existing cooling rolls, it is not necessary to rotate it synchronously, thereby eliminating the problem of defects caused by the conventional cooling rolls.
강판(1)에 걸리는 인장력과 자극(12)간의 거리, 자장세기, 가이드 에어노즐(14)의 분사력을 적절히 조절하면 강판(1)의 진동을 최소한으로 줄일 수 있다.By appropriately adjusting the tension between the steel plate 1 and the distance between the magnetic pole 12, the magnetic field strength, and the injection force of the guide air nozzle 14, the vibration of the steel sheet 1 can be reduced to a minimum.
[실시예]EXAMPLE
도 3을 참조하여 본 발명의 실시예를 설명한다. 길이 3m인 강판(1)을 수직으로 상하에서 고정시켜 설치하고, 그 중앙부에 자극(12)간 간격이 500mm인 전자석(18)을 설치하였다. 자극(12)과 자극(12)사이의 중심부에 폭 250mm, 슬릿간격 2mm인 에어노즐(14)을 설치하였다. 자극(12) 선단과 에어노즐(14) 선단간의 상대 거리(15)는 에어노즐(14)을 전후로 이동시켜 조절할 수 있도록 하였다.An embodiment of the present invention will be described with reference to FIG. 3. The steel plate 1 having a length of 3 m was fixed vertically up and down, and an electromagnet 18 having a 500 mm spacing between the magnetic poles 12 was installed at the center thereof. An air nozzle 14 having a width of 250 mm and a slit interval of 2 mm was provided at the center between the pole 12 and the pole 12. The relative distance 15 between the tip of the pole 12 and the tip of the air nozzle 14 was adjusted to move the air nozzle 14 back and forth.
폭 200mm, 두께 0.8mm, 길이 3m인 아연도금 강판(1)을 상하에서 고정구(16)를 이용하여 고정시켜 수직으로 설치한 후 강판(1)과 자극(12)간의 간격(17)이 60mm, 자극(12)간 간격 500mm, 자극(12)으로부터 에어노즐(14)이 돌출한 거리(15)를 50mm로 하고, 강판(1)의 최대 진동폭이 10mm가 되도록 임의로 진동을 일으키게 한 후 진동이 완전소멸할 때까지의 시간을 측정한 결과 약 10초가 걸렸으나, 같은 조건에서 강판(1)에서 자장이 0.1 테슬라가 되도록 전자기장을 인가하고 동시에 에어노즐(14)로부터 공기를 0.3바(bar)의 공기압으로 분출시킨 경우에는 전자기장을 인가함과 동시에 진동이 멈추었으며, 강판(1)은 에어노즐(14)로부터 약 1.5-2mm정도 떨어져 있었다. 또한, 자장을 인가하지 않은 상태에서 최대 10mm의 진동을 일으킬 수 있는 힘을 자장을 인가한 상태에서 부과한 경우에는 강판(1)에 진동이 발생하지 않았다.The galvanized steel sheet 1 having a width of 200 mm, a thickness of 0.8 mm, and a length of 3 m was fixed vertically using the fixture 16 at the top and bottom, and then installed vertically. The interval 17 between the steel sheet 1 and the pole 12 was 60 mm, The distance between the magnetic poles 12 and 500 mm and the distance 15 from which the air nozzles 14 protrude from the magnetic poles 12 are 50 mm, and the vibration is completely completed after causing the vibration to occur arbitrarily so that the maximum vibration width of the steel sheet 1 is 10 mm. As a result of measuring the time until dissipation, it took about 10 seconds, but under the same conditions, an electromagnetic field was applied so that the magnetic field became 0.1 tesla on the steel sheet 1, and at the same time, air pressure of 0.3 bar was applied from the air nozzle 14. In the case of spraying with an electromagnetic field, the vibration stopped as soon as the electromagnetic field was applied, and the steel sheet 1 was about 1.5-2 mm away from the air nozzle 14. In addition, when a force capable of causing a vibration of up to 10 mm without applying a magnetic field was applied in the state where the magnetic field was applied, no vibration occurred in the steel sheet 1.
이상과 같은 결과로부터, 본 발명을 사용하는 경우 용융아연 도금공정중에 제품품질에 큰 악영향을 끼치는 강판의 진동을 효과있게 억제할 수 있다는 것을 확인하였다.From the above results, it was confirmed that in the case of using the present invention, it is possible to effectively suppress the vibration of the steel sheet, which greatly affects the product quality during the hot dip galvanizing process.
상술한 바와 같이 본 발명은 직류 전자석과 강판 가이드 에어노즐을 용융아연 도금설비의 유지대와 냉각대 사이에 설치하여 강판의 진동현상을 방지하면서 강판의 냉각능을 향상시킬 수 있는 기술로, 강판의 진동방지로 도금량 편차를 줄여 더욱 우수한 품질의 용융아연도금 강판을 제조해내도록 할 수 있는 효과를 제공하는 것이다.As described above, the present invention is a technology that can improve the cooling capacity of the steel sheet while preventing the vibration phenomenon of the steel sheet by installing a direct current electromagnet and steel guide air nozzle between the holding and cooling stage of the hot-dip galvanizing equipment, The anti-vibration reduces the amount of plating, thereby providing the effect of producing a better quality hot-dip galvanized steel sheet.
