Description
본 고안은 연속소둔설비의 급속냉각대에 관한 것으로, 특히 급속냉각대에 설치되는 체임버로 부터 분사되는 냉각가스가 상승되면서 롤의 양에지(Edge)부가 냉각되는 현상을 미연에 방지함으로써 철판의 품질을 향상시킬 수 있는 연속소둔설비의 급속냉각대에 관한 것이다.The present invention relates to a rapid cooling stage of a continuous annealing equipment, and in particular to prevent the cooling of the edge edge of the roll as the cooling gas injected from the chamber installed in the rapid cooling stage to prevent the quality of the iron plate It relates to a rapid cooling stage of the continuous annealing equipment that can improve the.
일반적으로 연속소둔설비중 급속냉각대(Rapid Cooling Section)는 제1도에 도시한 바와같이 가열 대에서 철판(9)을 가열한 후 체임버(10)를 통과하는 철판을 분사노즐(1)로 부터 분사되는 냉각가스를 이용하여 급속냉각시킨다.In general, the rapid cooling section of the continuous annealing equipment heats the iron plate 9 in the heating table as shown in FIG. 1 and then passes the iron plate passing through the chamber 10 from the injection nozzle 1. Rapid cooling using the injected cooling gas.
그리고 체임버(10)를 통과한 철판(9)은 냉각롤(6)을 거치면서 급속냉각되어 과시효대로 빠져나가게 되는데, 이때 급속냉각대를 거치면서 50∼100℃/sec의 냉각속도로 급속냉각된 철판은 고용탄소량이 증대되면서 고공탄소의 과포화도 향상으로 다음단계인 과시효대에서 고용탄소가 쉽게 석출된다.And the iron plate (9) passed through the chamber (10) is rapidly cooled while passing through the cooling roll (6) to exit the overaging aging, at this time through the rapid cooling stage rapid cooling at a cooling rate of 50 ~ 100 ℃ / sec As the amount of carbon used is increased, the supersaturation of high carbon is improved, and the carbon is easily precipitated at the next stage of overaging.
그러나 급속냉각대에서 철판(9)이 통과되는 냉각롤(6)은 중앙부가 500~700℃의 철판에 의해 고온의 상태가 되지만, 양에지부가 분사노즐(1)로 부터 분사되는 냉각가스의 상승에 의해 냉각되어 철판에 서멀크라운(Thermal Crown)이 발생된다.However, the cooling roll 6 through which the iron plate 9 passes in the quick cooling zone has a high temperature by the iron plate of 500 to 700 ° C., but both edge portions of the cooling gas are injected from the injection nozzle 1. It cools by rising and a thermal crown is generated in an iron plate.
또한 냉각된 냉각롤(6)의 양에지부에 의해 서멀크라운(Thermal Crown)이 발생되는 철판(9)은 판형상이 더욱 악화되면서 냉각버클(Cooling Buckle)이 발생되고, 최악의 경우 판파단이 발생되는 경우도 있다.In addition, the iron plate 9 in which the thermal crown is generated by both edges of the cooled cooling roll 6 is further deteriorated in plate shape, causing a cooling buckling, and in the worst case, breaking of the plate. In some cases.
한편 종래에는 체임버(10)의 냉각가스 및 과시효대측의 렝풍에 의해 냉각롤(6)의 양에지부가 냉각되는 현상을 방지하기 위하여 냉각롤의 상부에 가열기(7)을 별도 설치하였으나 그 효과가 크지 못하여 철판(9)의 서멀크라운(Thermal Crown)을 방지할 수 없었다.Meanwhile, in order to prevent the phenomenon in which both edge portions of the cooling roll 6 are cooled by the cooling gas of the chamber 10 and the long wind on the side of the aging band, a heater 7 is separately installed on the upper portion of the cooling roll. It was not so large that the thermal crown of the iron plate 9 could not be prevented.
본 고안은 차단판 및 실롤(Seal Roll)을 이용하여 체임버와 냉각롤을 격리시킴으로써 냉각가스가 냉각롤로 상승되는 현상을 방지하고, 이로써 철판의 품질을 항상시킬 수 있는 연속소둔설비의 급속냉각대를 제공함에 그 목적이 있다.The present invention prevents the rising of the cooling gas to the cooling roll by isolating the chamber and the cooling roll by using a blocking plate and a seal roll, thereby providing a rapid cooling stage of the continuous annealing equipment that can always ensure the quality of the steel sheet The purpose is to provide.

상기한 목적을 달성하기 위하여 본 고안은 연속소둔설비의 급속냉각대에 있어서, 냉각체임버의 냉각가스와 과시효대측으로 부터 불어오는 냉품에 의해 냉각롤로 양에지부가 냉각되는 현상을 방지하기 위하여 설치되면서 철판이 통과할 수 있도록 실롤이 설치되는 차단판과; 상기 냉각체임버의 최상측에 설치되면서 냉각가스를 하향되게 분사할 수 있도록 형성되는 분사노즐로 구성되는 것을 특징으로 하는 연속소둔설비의 급속냉각대를 제공한다.In order to achieve the above object, the present invention is installed in a rapid cooling zone of a continuous annealing facility, in order to prevent a phenomenon in which both edge portions are cooled by a cooling roll by a cooling gas blown from a cooling gas of a cooling chamber and a aging band side. A blocking plate on which a sil roll is installed so that the steel plate can pass therethrough; It is provided on the top of the cooling chamber to provide a rapid cooling zone of the continuous annealing equipment, characterized in that consisting of a spray nozzle which is formed to inject the cooling gas downward.
도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.
제2도는 본 고안에 따른 연속소둔설비의 급속냉각대를 나타내는 개략도이다.2 is a schematic view showing a rapid cooling zone of the continuous annealing equipment according to the present invention.
먼저 연속소둔설비에서 가열대의 상부에 설치되는 냉각체임버(Cooling Chamber)(10)는 중앙으로 통과하는 철판(9)에 냉각가스를 분사하기 위하여 내측 양쪽에 상하로 다수의 분사노즐(2)이 좌우 대칭되게 형성되어 있다.First, in the continuous annealing facility, the cooling chamber (Cooling Chamber) 10 installed on the upper part of the heating table has a plurality of injection nozzles 2 up and down on both inner sides to inject cooling gas to the iron plate 9 passing through the center. It is formed symmetrically.
이때 분사노즐(2)중 최상측에 형성되는 분사노즐은 약 5°정도 하향으로 냉각가스를 분사하도록 형성되어 있고, 이로써 냉각가스가 냉각롤(6)로 상승되는 현상을 억제할 수 있게 된다.At this time, the injection nozzles formed on the uppermost side of the injection nozzles 2 are formed to inject cooling gas downward by about 5 °, thereby suppressing the phenomenon that the cooling gas rises to the cooling roll 6.
그리고 냉각롤(6)과 냉각체임버(10)를 격리하기 위하여 설치되는 차단판(4)은 냉각체임버의 상부에 위치하는 급속냉각대의 내주면에 고정되면서 중앙부에 철판(9)이 통과할 수 있도록 홀(4-1)이 형성되어 있다.In addition, the blocking plate 4 installed to isolate the cooling roll 6 and the cooling chamber 10 is fixed to the inner circumferential surface of the quick cooling zone located at the upper portion of the cooling chamber, and allows the iron plate 9 to pass therethrough. (4-1) is formed.
또한 차단판(4)의 중앙홀(4-1)의 기밀을 위하여 상측에 실롤(Seal Roll)(5)이 설치되어 있고, 이 실롤을 통해 철판(9)이 통판된다.In addition, a seal roll 5 is provided on the upper side for airtightness of the central hole 4-1 of the blocking plate 4, and the iron plate 9 is passed through the seal roll.
한편 과시효대설비쪽에서도 차가운 바람이 냉각롤(6)측으로 유입되기 때문에 과시효대방향의 급속냉각대에도 차단판(14) 및 실롤(15)이 설치되어 있다.On the other hand, since the cold wind also flows to the cooling roll 6 side from the side of the aging system, the blocking plate 14 and the sil roll 15 are also provided in the rapid cooling zone in the direction of aging.
이하 본 고안의 작용을 설명한다.Hereinafter will be described the operation of the present invention.
연속소둔설비중 가열대에서 가열된 철판(9)이 1차 냉각된 후 재냉각되기 위하여 급속냉각대의 냉각체임버(Cooling Chamber)(10)를 수직으로 관통하게 되는데, 이때 냉각체임버(Cooling Chamber)(10)의 분사노즐(2)에서는 냉각가스가 고속으로 분사되면서 지나가는 철판을 냉각시키게 된다.The iron plate 9 heated in the heating table in the continuous annealing equipment passes through the cooling chamber 10 of the rapid cooling zone vertically to be recooled after the first cooling, in which case the cooling chamber 10 In the injection nozzle (2) of the cooling gas is injected at a high speed to cool the passing iron plate.
이때 냉각체임버(Cooling Chamber)(10)의 최상부에 설치되는 분사노즐(2)은 다른 분사노즐과 달리 약간 하향되게 냉각가스를 분사하기 때문에 냉각가스의 상승을 상당히 억제할 수 있게 된다.At this time, since the injection nozzle 2 installed at the top of the cooling chamber 10 injects the cooling gas slightly downward unlike other injection nozzles, the rise of the cooling gas can be significantly suppressed.
그리고 냉각체임버(Cooling Chamber)(10)를 통과한 철판(9)은 차단판(4)의 홀(4-1)을 지나 실롤(Seal Roll)(5) 사이를 통과하게 되고, 이때 냉각가스는 차단판(4)과 실롤(5)에 의해 냉각롤(6)로 상승되는 것이 방지된다.And the iron plate (9) passing through the cooling chamber (Cooling Chamber) 10 passes through the hole (4-1) of the blocking plate 4 between the seal roll (Seal Roll) (5), wherein the cooling gas Lifting to the cooling roll 6 by the blocking plate 4 and the seal roll 5 is prevented.
한편 차단판(4) 및 실롤(5)을 수직으로 통과한 철판(9)은 냉각롤(6)을 거쳐 직각으로 절곡되면서 과시효대측으로 이동하게 되는데, 이때 과시효대측으로 빠져 나가기전에 실롤(15)파 차단판(14)을 차례로 수평 통과하게 된다.Meanwhile, the iron plate 9 vertically passing through the blocking plate 4 and the silol 5 is bent at a right angle through the cooling roll 6 to move to the overaging side, in which case the silol 15 before exiting to the overaging side. The wave blocking plate 14 is sequentially horizontally passed through.
여기서 냉각롤(6)과 과시효대측의 급속냉각대 사이가 차단판(14) 및 실롤(15)에 의해 차단되어 냉각롤(6)이 과시효대측에서 불어오는 차가운 바람에 의해 냉각되는 것이 방지된다.Here, between the cooling roll 6 and the rapid cooling zone on the overaging side is blocked by the blocking plate 14 and the sil roll 15 to prevent the cooling roll 6 from being cooled by the cold wind blowing from the overaging side. do.
따라서 급속냉각대의 절곡부에 내장되는 냉각롤(6)은 차단판(4,14) 및 실롤(5,15)에 의해 보온되면서 가열기(7)에 의해 가열됨으로써 철판(9)의 양에지에 발생되는 서멀크라운(Thermal Crowon)이 억제된다.Accordingly, the cooling roll 6 embedded in the bent portion of the quick cooling zone is heated by the heater 7 while being kept warm by the blocking plates 4 and 14 and the seal rolls 5 and 15 to be generated on both edges of the iron plate 9. Thermal Crowon is suppressed.
본 고안은 차단판 및 실롤(Seal Roll)을 이용하여 체임버와 냉각롤을 격리시킴으로써 냉각가스가 냉각롤로 상승되는 현상을 방지하고, 이로써 철판의 품질을 향상시킬 수 있는 효과를 제공한다.The present invention prevents the rising of the cooling gas to the cooling roll by isolating the chamber and the cooling roll by using a barrier plate and a seal roll, thereby providing an effect of improving the quality of the iron plate.
