본 발명은 권취코일 냉각장치에 관한 것으로서, 더욱 상세하게는 열간압연 후 권취된 열연코일을 기계적 성질의 변화 없이 빠른 시간에 효율적으로 냉각시킬 수 있도록 한 권취코일 냉각장치에 관한 것이다.The present invention relates to a winding coil cooling device, and more particularly, to a winding coil cooling device capable of efficiently cooling a wound hot rolled coil after hot rolling without changing mechanical properties.

일반적으로 열연코일을 냉각상태에서 조질압연(형상교정)을 하려면 상온 즉 40℃ 정도로 냉각시켜 작업을 해야 하는데, 상기 열간 압연된 권취코일은 평균 600℃정도로서, 조질압연이 가능한 상온상태까지 냉각시키기 위해서는 동절기에는 2∼3일이 소요되고 하절기에는 4∼5일이 소요된다.In general, in order to perform the rough rolling (shape correction) of the hot rolled coil in a cooled state, the hot rolled coil should be cooled to about room temperature, that is, about 40 ° C. It takes 2-3 days in winter and 4-5 days in summer.

따라서 상기 권취코일의 냉각기간을 단축시키기 위하여 종래에는 도 1에 나타낸 바와 같이 옥내에 일렬로 여러개 적치된 코일의 일 측면에 송풍기(B)를 설치하여 권취코일(C) 측으로 송풍을 하고 있으나 이는 송풍기(B)와 근접된 위치의 권취코일(C)은 어느 정도 효과를 볼 수 있으나 송풍기(B)와 먼 거리에 위치한 권취코일(C)은 효과를 볼 수 없는 문제점이 있었다.Therefore, in order to shorten the cooling period of the coiling coil, as illustrated in FIG. 1, a blower B is installed at one side of a coil stacked several times in a row indoors to blow the winder toward the coiling coil C. Winding coil (C) of the position close to (B) can see the effect to some extent, but the winding coil (C) located in the far distance with the blower (B) had a problem that can not see the effect.

또 상기 송풍기(B)와 먼 거리에 위치한 권취코일(C)은 송풍기(B)와 근접된 위치의 권취코일(C)이 냉각되면서 방출되는 열기가 전달되어 오히려 냉각의 시간이 지연되는 문제점도 발생하였다.In addition, the winding coil (C) located at a long distance from the blower (B) is a problem that the cooling time is delayed due to the heat delivered by the winding coil (C) in the position close to the blower (B) is transmitted It was.

따라서 근래에는 상기의 문제점을 해소하고자 도 2에 나타낸 바와 같이 권취코일(C)이 적재되는 사이사이에 냉각수분사수단(10)을 마련하여 냉각수를 분사함으로서 냉각속도를 단축시키고 있으나 이는 강판의 조직을 변형시키는 문제점이 있고, 또 권취코일(C)의 표면 및 주위설비를 부식시키는 문제점이 있다.Therefore, in order to solve the above problem, as shown in FIG. 2, the cooling water spraying means 10 is provided between the winding coils C to be loaded to shorten the cooling speed by spraying the cooling water. There is a problem of deforming, and there is a problem of corroding the surface of the winding coil (C) and the peripheral equipment.

그리고 상기 냉각수분사수단(10)은 권취코일(C)이 적재되는 사이사이에 파이프(11)가 배열되어야 하고 그 배열된 파이프(11)에는 냉각수분사노즐(12)이 일정간격으로 설치되어 있는 바, 상기 파이프(11)와 냉각수분사노즐(12)은 크레인을 이용 한 권취코일(C) 적재 작업시 장해요인이 되고 있다. And the cooling water injection means 10 is a pipe 11 is arranged between the coiling coil (C) is loaded and the arrangement of the cooling water spray nozzles 12 at a predetermined interval bar In addition, the pipe 11 and the cooling water spray nozzle 12 are obstacles in the winding coil C loading operation using a crane.

본 발명은 상기와 같은 문제점을 감안하여 이를 해소하고자 발명한 것으로서, 그 목적은 권취코일을 안착시키는 권취코일 냉각장치를 마련하여 이에 냉각수와 냉각에어를 주입함으로서 발생하는 냉기를 이용하여 권취코일을 신속하게 냉각시키도록 한 권취코일 냉각장치를 제공함에 있다. The present invention has been made to solve the above problems, the object of the present invention is to provide a coiling coil cooling device for seating the coiling coil by using the cold air generated by injecting cooling water and cooling air to the coiling coil quickly It is to provide a winding coil cooling apparatus for cooling.

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 향하 도록 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 in the air injection pipe so as to pass through 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 권 취코일(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 regular intervals along the width direction of the winding coil C, cooling air is evenly sprayed on the winding coil C evenly.

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.
