권취코일이 위치하는 저부에는 내부에 공간이 형성되고 일 측에 공간으로 냉각수를 공급할 수 있는 냉각수주입구가 형성된 권취코일받침부;A winding coil support portion having a cooling water inlet for supplying cooling water to a space at one side thereof and having a space formed therein;

상기 권취코일받침부의 양측으로 권취코일의 높이와 준하는 높이를 갖으며 내부에 상기 권취코일받침부의 공간과 연통하는 공간이 형성되고 상부에는 냉각수배출구가 형성된 권취코일보호부;A winding coil protection part having a height corresponding to a height of the winding coil on both sides of the winding coil support part and communicating with a space of the winding coil support part, and having a cooling water outlet formed thereon;

상기 권취코일보호부의 공간에 마련되어 권취코일의 측면에 냉각에어를 분사하도록 마련된 에어냉각수단을 포함하도록 되어 있다.It is provided in the space of the winding coil protection unit is to include an air cooling means provided to inject cooling air to the side of the winding coil.

그리고 권취코일보호부는 권취코일의 외부를 감싸도록 호형으로 형성되어 있고, 또 상기 에어냉각수단은 권취코일보호부의 코너부분 공간에 에어공급구가 형성된 에어저장실이 마련되고 그 에어저장실에는 일정간격으로 에어분사파이프가 형성되며 상기 에어분사파이프에는 권취코일보호부를 관통하며 권취코일의 표면을 향하도록 에어분사노즐이 형성되어 있다.The winding coil protection part is formed in an arc shape so as to surround the outside of the winding coil, and the air cooling means is provided with an air storage chamber in which an air supply port is formed in a corner portion of the winding coil protection part, and the air storage chamber has air at a predetermined interval. An injection pipe is formed, and the air injection pipe is formed to penetrate the winding coil protection part and face the surface of the winding coil.

한편 상기 에어분사노즐은 권취코일에 대하여 상하방향으로 적어도 2개 이상 형성되어 있다.On the other hand, at least two air spray nozzles are formed in the vertical direction with respect to the coiling coil.

상기와 같은 특징을 갖는 본 발명의 권취코일 냉각장치를 첨부도면을 참조하여 상세하게 설명하면 다음과 같다.Referring to the winding coil cooling apparatus of the present invention having the characteristics as described above in detail with reference to the accompanying drawings.

본 발명은 먼저 권취코일 냉각장치에 크레인(도면 미도시)을 이용하여 600℃정도 되는 열간 압연된 권취코일(C)을 안착시킨 후 냉각수주입구(22)를 통하여 냉각수를 주입하게 되면 그 냉각수는 권취코일받침부(20)의 공간(21)을 통하여 권취코일보호부(30)의 공간(31)으로 진행하면서 냉각수배출구(32)로 배출된다.The present invention first seats the hot-rolled winding coil (C) of about 600 ℃ by using a crane (not shown) in the coiling coil cooling device, and then when the cooling water is injected through the cooling water inlet 22, the cooling water is wound up. The air is discharged to the cooling water discharge port 32 while proceeding to the space 31 of the winding coil protection unit 30 through the space 21 of the coil support unit 20.

따라서 상기 권취코일받침부(20)와 권취코일보호부(30)는 냉각수에 의하여 냉각되면서 냉기가 방출되게 되고 그 방출되는 냉기는 권취코일(C)에서 방출되는 열기를 흡수한다. 그러므로 상기 권취코일(C)은 냉각속도가 빨라지게 되는 것이다.Therefore, the coiling coil support 20 and the coiling coil protection unit 30 is cooled by the cooling water to be discharged cold air and the released cold air absorbs the heat released from the coiling coil (C). Therefore, the winding coil (C) is to increase the cooling rate.

또한 본 발명은 권취코일보호부(30)의 코너부분 공간(31)에 형성된 에어저장실(41)의 에어공급구(42)에 냉각에어를 공급하게되면 그 공급되는 냉각에어는 상기 에어저장실(41)에 일정간격으로 형성된 에어분사파이프(43)를 통하여 에어분사노즐(44)로 분사되면서 권취코일(C)의 표면에 미치게 되어 상기 권취코일(C)을 냉각시키게 되는 것이다.In addition, in the present invention, when the cooling air is supplied to the air supply port 42 of the air storage chamber 41 formed in the corner space 31 of the winding coil protection unit 30, the supplied cooling air is the air storage chamber 41. ) Is injected into the air spray nozzle 44 through the air spray pipe 43 formed at a predetermined interval to reach the surface of the coiling coil C to cool the coiling coil C.

단 상기 에어분사파이프(43)에 형성된 에어분사노즐(44)은 권취코일(C)에 대하여 상하방향으로 적어도 2개 이상 형성되어 있기 때문에 냉각에어가 권취코일(C)에 골고루 분사되는 것이고, 에어저장실(41)에 형성된 에어분사파이프(43) 역시 권취코일(C)의 폭 방향을 따라 일정간격으로 형성되어 있기 때문에 권취코일(C)에 냉각에어가 골고루 균일하게 분사되는 것이다.However, since at least two air spray nozzles 44 formed on the air spray pipe 43 are formed in the vertical direction with respect to the coiling coil C, cooling air is evenly sprayed on the coiling coil C, and air Since the air spray pipe 43 formed in the storage chamber 41 is also formed at a predetermined interval along the width direction of the winding coil C, cooling air is uniformly sprayed on the winding coil C.

따라서 상기 권취코일 냉각장치에 안착된 600℃정도의 열간 압연된 권취코일(C)은 빠른 시간에 효율적으로 냉각이 이루어져 후 공정 즉 조질압연(형상교정)을 할 수 있음으로 생산성을 높일 수 있는 장점이 있다.Therefore, the hot rolled winding coil (C) of about 600 ° C. seated on the winding coil cooling device has an advantage of being able to increase productivity by performing cooling after a rapid process, that is, temper rolling (shape correction). There is this.

이상과 같은 본 발명은 열간 압연된 열연 권취코일을 조질압연(형상교정)하기 위하여 냉각시킬 때에 권취코일의 조직변화 없이 빠른 시간에 냉각시킬 수 있는 특유의 효과가 있다.The present invention as described above has a peculiar effect of cooling the hot rolled hot rolled coil to be temperally rolled (shape corrected) without any change in the structure of the coil.

또한 본 발명은 열간 압연된 열연 권취코일을 냉각시키기 위하여 냉각수를 사용하지 않기 때문에 권취코일 및 주위설비의 부식 없이 안전하게 냉각시킬 수 있는 특유의 효과가 있다.In addition, since the present invention does not use cooling water to cool the hot rolled hot rolled coil, the present invention has a unique effect of safely cooling without corrosion of the coil and surrounding equipment.
