본 발명은 용융아연도금 공정에서 아연포트를 통과하여 표면에 용융아연이 부착된 강판을 냉각하는 용융도금강판 냉각장치에 관한 것으로, 보다 상세하게는 아연포트를 통과하여 용융아연이 부착된 강판의 표면에 냉각된 공기를 분사하여 강판을 냉각시키는 용융도금 스트립 냉각장치에 관한 것이다.The present invention relates to a hot-dip galvanized steel sheet cooling apparatus for cooling a steel sheet with a hot-dip zinc attached to the surface by passing through the zinc port in the hot-dip galvanizing process, more specifically, the surface of the steel sheet is attached to the hot-dip zinc is passed through the zinc port It relates to a hot-dip plating strip cooling apparatus for cooling the steel sheet by spraying the air cooled.

일반적으로 용융도금에서 스트립은 가열로를 통과하면서 예열되고, 예열된 스트립은 아연포트를 통과 시키면서 표면에 용융아연을 균일하게 도금시키게 된다.In hot dip galvanizing, the strips are preheated while passing through the furnace, and the preheated strips are uniformly plated with molten zinc on the surface while passing through the zinc pot.

이와 같이 용융도금강판의 도금은 도 1에 도시된 바와 같이 아연포트(4)를 통과하여 용융아연이 부착된 강판(1)은 나이프(3)에 의해 용융아연이 균일한 두께로 커팅되며, 커팅된 강판(1)은 쿨링 블로워가 설치된 냉각장치(2)를 통과하면서 냉각된 공기가 강판(1)에 분사되므로 용융아연이 부착된 강판(1)은 냉각된다.As described above, the plating of the hot-dip galvanized steel sheet passes through the zinc port 4 and the hot-dip galvanized steel sheet 1 is cut to a uniform thickness by the knife 3 and cut by the knife 3. Since the cooled steel is injected into the steel sheet 1 while passing through the cooling apparatus 2 provided with the cooling blower, the steel sheet 1 with molten zinc is cooled.

즉, 강판(1)의 상부에 코팅된 액체아연층이 냉각된 공기에 의해서 고체아연층으로 급냉각되면서 강판(1)의 표면에는 스팽글(Spangle)이 발생된다.That is, as the liquid zinc layer coated on the upper portion of the steel sheet 1 is rapidly cooled into the solid zinc layer by the cooled air, spangles are generated on the surface of the steel sheet 1.

한편 냉각장치를 통한 강판(1)의 냉각은 강판(1)의 폭방향 중심부 온도를 측정하여 냉각곡선에 따라 냉각된 공기를 냉각대의 노즐을 통하여 분사하므로 용융아연이 부착된 강판(1)을 냉각하였다.On the other hand, the cooling of the steel sheet 1 through the cooling device measures the central temperature in the width direction of the steel sheet 1 and injects air cooled according to the cooling curve through the nozzle of the cooling table, thereby cooling the steel sheet 1 with molten zinc. It was.

그러나 위와 같은 용융도금강판은 폭 방향 전체에 동일한 양의 냉각된 공기가 분사되므로 용융도금강판의 부분별 열전달의 차이에 따라 아연 스팽글이 필요 이상으로 커지므로 스트립의 냉각효과가 저하되는 문제점이 있다. However, since the same amount of cooled air is injected in the entire width direction, the hot dip galvanized steel sheet has a problem in that the cooling effect of the strip is lowered because the zinc sequins become larger than necessary according to the difference in heat transfer for each part of the hot dip galvanized steel sheet.                         

또한 아연 스팽글의 형성이 일정하지 못하므로 제품의 품질이 떨어지는 문제점이 있다.In addition, since the formation of zinc sequins is not constant, there is a problem in that the quality of the product falls.

한편 스트립감지센서(163)가 엣지부를 감지 할 때까지 이동실린더(164)가 작동되어 냉각수박스(160)가 용융도금강판(101)의 엣지부와 일정한 간격을 유지하도록 제어한다.Meanwhile, the moving cylinder 164 is operated until the strip detecting sensor 163 detects the edge portion to control the coolant box 160 to maintain a constant distance from the edge portion of the molten plated steel sheet 101.

또한 제어패널은 냉각수공급관(140)에 냉각수가 공급되도록 제어함과 동시에 용융도금강판(101)의 폭 만큼 냉각수밸브(142)가 개방되어서 냉각수노즐(141)을 통하여 냉각수를 분사되도록 하며 에어노즐(151)에 공기를 공급하여 냉각수노즐(141)에서 분사되어 용융도금강판(101)을 타고 내려오는 냉각수가 에어노즐(151)에 의해 좌우로 밀려서 제거되도록 하고, 제거된 냉각수는 냉각수박스(160)로 배출된 후, 드레인 관(166)으로 배출된다.In addition, the control panel controls the cooling water to be supplied to the cooling water supply pipe 140, and at the same time, the cooling water valve 142 is opened by the width of the molten plated steel plate 101 so that the cooling water is injected through the cooling water nozzle 141, and the air nozzle ( Air is supplied to the 151 to be injected from the coolant nozzle 141 to remove the coolant coming down the molten plated steel sheet 101 by being pushed from side to side by the air nozzle 151, the removed coolant is the coolant box 160 After discharged to the drain pipe 166 is discharged.

이상 설명한 바와 같은 본 발명에 따른 용융도금강판의 냉각장치는 용융도금강판의 냉각시 양측에 설치된 온도감지센서에 의해 감지된 온도에 따라 냉각된 공기의 공급량이 조절 되므로 아연 스팽글이 균일하게 형성되어 스트립의 냉각효과가 커진다.The cooling apparatus of the hot-dip galvanized steel sheet according to the present invention as described above, since the supply amount of the cooled air is controlled according to the temperature detected by the temperature sensor installed on both sides during cooling of the hot-dip galvanized zinc sequins are formed uniformly strip Increases the cooling effect.

또한 냉각된 공기의 공급량이 조절되므로 아연 스팽글이 일정하게 형성되어 제품의 품질이 향상된다.In addition, since the supply amount of the cooled air is controlled, zinc sequins are uniformly formed, thereby improving product quality.
