본 발명은 스테인레스스틸을 광휘소둔로로 진입시키는 과정에서 이용되는 루프카에 관한 것으로, 특히 루프카의 바닥면에 설치되는 스티어링롤의 기울기를 자동으로 조정되게하여 스트립의 쏠림현상을 교정시킬 수 있도록 된 소둔로내 진입 스트립 포지션 교정장치에 관한 것이다. The present invention relates to a roof car used in the process of entering the stainless steel into the bright annealing furnace, and in particular to automatically adjust the inclination of the steering roll installed on the bottom surface of the roof car to correct the deflection of the strip. The present invention relates to an entrance strip position corrector in an annealing furnace.

일반적으로, 스테인레스스틸(stainless steel)은, 냉연공정에서 성형되어진 스트립을 재결정의 형성이나 재료의 연화를 위한 수단으로 산화성분위기의 소둔로에서 열처리하는 과정에서 그 외표면을 따라 산화스케일이 형성되는데, 이러한 산화스케일은 산세공정을 통해 제거된다. In general, stainless steel is an oxide scale formed along the outer surface of a strip formed in a cold rolling process by heat treatment in an annealing furnace of an oxidative atmosphere as a means for recrystallization or softening of a material. This oxide scale is removed through a pickling process.

여기서, 스테인레스스틸의 스트립은, 산세공정을 거치면서 외표면의 산화스케일들이 제거되는 특징이 있는 반면 외표면의 거칠기가 증가되어 광택성이 저하되는 단점이 있으므로, 이러한 산세공정을 거친 스트립을 루프카를 이용하여 환원성분위기의 광휘소둔로로 진입시키게 된다. Here, the strip of stainless steel is characterized in that the oxidation scales of the outer surface are removed during the pickling process, whereas the roughness of the outer surface is increased so that the glossiness is degraded. It is used to enter the bright annealing furnace of the reducing component crisis.

즉, 도 1에서와 같이, 스테인레스스틸의 스트립(S)이 디플렉터롤(110)을 통해 굴절된 상태에서 루프카(200)내로 유도되어, 루프카(200)의 상하부에 각각 구비된 다수개의 루프롤(210)과 스티어링롤(220)을 통해 경유하여 브라이들롤(230)에 의해 안내되어 광휘소둔로(300)로 진입된다. That is, as shown in Figure 1, the stainless steel strip (S) is guided into the roof car 200 in a state refracted through the deflector roll 110, a plurality of loops respectively provided on the upper and lower parts of the roof car 200 Guided by the bridle roll 230 via the roll 210 and the steering roll 220 enters the bright annealing path 300.

이때, 루프카(200)의 루프롤(210)이 승하강을 반복하는 과정에서 스트립(S)의 자체형상의 불량으로 인해 일방향으로 쏠리는 경우, 교정장치(미도시)를 이용하여 스티어링롤(220)의 센터를 조정하여 스트립의 위치를 바로잡은 다음 광휘소둔로 (300)로 진입시키게 되는 것이다. At this time, when the roof roll 210 of the roof car 200 is pulled in one direction due to a poor shape of the strip S in the process of repeatedly moving up and down, the steering roll 220 using a calibration device (not shown). The center of the strip is adjusted to correct the position of the strip and then enters the bright annealing furnace 300.

그런데, 스티어링롤(220)의 센터조정이 별도의 교정장치를 통해 이루어지므로 작업과정이 매우 어려워 작업하중이 증대될 뿐만 아니라 교정장치의 작동과정에서 조정불량으로 인해 스트립(S)의 에지부가 주변기기와 충돌하는 경우 스트립이 파단될 우려가 있는 문제점이 있었다. However, since the center adjustment of the steering roll 220 is made through a separate calibration device, the work process is very difficult and the work load is increased, and the edge part of the strip S is misaligned with the peripheral device due to the misalignment during the operation of the calibration device. In case of collision, there was a problem that the strip may be broken.

또한, 스티어링롤(220)의 센터조정에 따른 작업과정에서 파단되어진 칩들이 스트립(S)의 표면에 묻은 상태에서 그대로 진행하는 경우 각 롤에 박혀 손상시킬 우려가 있음을 물론, 스트립(S)에 묻은 칩들을 제거하기 위해서는 연속라인의 설비를 정지시켜야 하므로 작업생산성이 저하되는 문제점이 있었다. In addition, if the chip is broken in the process according to the center adjustment of the steering roll 220 in the state of being stuck on the surface of the strip (S) of course there is a risk of being stuck in each roll, of course, to the strip (S) In order to remove the chips, it is necessary to stop the equipment of the continuous line, there is a problem that the work productivity is reduced.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 스트립이 루프카를 통해 광휘소둔로로 진입하는 과정에서 루프롤의 기울기를 조정하여 스트립을 안정되게 광휘소둔로로 진입시킬 수 있도록 된 소둔로내 진입 스트립 포지션 교정장치를 제공하는 데에 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, by adjusting the slope of the roof roll in the process of entering the light annealing furnace through the loop car can stably enter the strip annealing furnace. It is an object of the present invention to provide a device for correcting an entry strip position in an annealing furnace.

물론, 이동베이스(40)의 지지바(44)에는, 베어링블럭(41)을 통해 수평방향으로 스티어링롤(220)이 장착되어, 예컨대 승강실린더(33)의 로드가 축소/확장되는 과정에서 스티어링롤(220)을 일방향으로 회동시켜, 스트립(S)의 쏠림현상을 교정하는 기능을 수행하게 되는 것이다. Of course, the support bar 44 of the movable base 40, the steering roll 220 is mounted in the horizontal direction through the bearing block 41, for example, the steering in the process of reducing / expanding the rod of the lifting cylinder 33 By rotating the roll 220 in one direction, it is to perform the function of correcting the pulling phenomenon of the strip (S).

그리고, 제어부(50)는, 좌우감지센서(13,14)의 신호를 입력받아 좌우실린더 (24,25)로 작동신호를 출력함과 더불어 포지션센서(32)의 신호를 입력받아 승강실린더(33)로 작동신호를 출력한다. In addition, the controller 50 receives the signals from the left and right detection sensors 13 and 14, outputs an operation signal to the left and right cylinders 24 and 25, and receives the signal from the position sensor 32. To output the operation signal.

이하, 본 발명에 따른 작용을 첨부된 예시도면을 참고로하여 상세하게 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings illustrating the operation according to the present invention.

먼저, 스트립(S)이 루프카(200)내로 유도된 상태에서, 루프카(200)의 롤고정프레임(240)에 축설치되어진 루프롤(210)과 스티어링롤(220)을 경유하여 광휘소둔로(300)내로 진입되는 과정에서, 스트립(S)의 이동루트가 투광기(11)와 수광기(12)에 의해 지속적으로 감지된다. First, in the state in which the strip S is guided into the roof car 200, the light annealing is performed via the roof roll 210 and the steering roll 220 that are axially installed on the roll fixing frame 240 of the roof car 200. In the course of entering the furnace 300, the moving route of the strip S is continuously sensed by the transmitter 11 and the receiver 12.

이때, 스트립(S)이 자체형상의 불량으로 인해 일방향으로 쏠리는 경우, 좌측감지센서(13) 또는 우측감지센서(14)의 신호를 입력받은 제어부(50)에서는 교정장치(20)의 좌측실린더(24) 또는 우측실린더(25)로 작동신호를 출력함과 동시에 좌측경보센서(15) 또는 우측경보센서(16)로 경보음의 발생신호를 출력한다. At this time, when the strip S is pulled in one direction due to a defect in its own shape, the control unit 50 which receives the signal of the left sensor 13 or the right sensor 14 receives the left cylinder of the calibration apparatus 20. 24) or outputs the operation signal to the right cylinder (25) and at the same time outputs the alarm signal generation signal to the left alarm sensor 15 or the right alarm sensor (16).

예컨대, 스트립(S)이 좌측감지센서(14)에 의해 감지되는 경우 즉, 스트립이 좌측방향으로 쏠리게 되는 경우, 제어부(50)의 신호를 입력받은 좌측실린더(24)의 로드가 축소되므로, 교정장치(20)의 차단판(22,23)이 도면상 레일(21)을 따라 우측방향으로 이동되는 것이다. For example, when the strip S is detected by the left sensor 14, that is, when the strip is inclined in the left direction, the load of the left cylinder 24 receiving the signal from the controller 50 is reduced, so that the calibration is performed. The blocking plates 22 and 23 of the device 20 are moved to the right along the rail 21 in the drawing.

이 경우, 교정장치(20)의 차단판(22,23)이 도면상 우측방향으로 이동하였다는 의미는, 투광기(11)에 대해 수광기(12)가 도면상 우측방향으로 이동하였다는 것을 의미하는 것이다. In this case, the meaning that the blocking plates 22 and 23 of the calibration device 20 moved in the right direction on the drawing means that the light receiver 12 has moved in the right direction on the drawing with respect to the light projector 11. It is.

이때, 제어부(50)에서는 수광기(12)의 신호를 입력받아 포지션센서(32)로 작동신호를 출력하므로, 승강실린더(33)의 로드가 확장된다. 즉, 승강실린더(33)의 로드가 확장되는 과정에서 고정베이스(30)의 회동축(31)에 결합되어 있던 이동베이스(40)가 도면상 반시계방향으로 회동된다. At this time, since the control unit 50 receives a signal from the light receiver 12 and outputs an operation signal to the position sensor 32, the load of the lifting cylinder 33 is expanded. That is, in the process of expanding the rod of the lifting cylinder 33, the moving base 40 coupled to the rotation shaft 31 of the fixed base 30 is rotated counterclockwise in the drawing.

이 과정에서, 이동베이스(40)의 경사면에 베어링블럭(41)을 통해 장착되어있던 스티어링롤(220)이 도면상 반시계방향으로 회동되므로, 스티어링롤(220)에 좌측방향으로 쏠려있던 스트립(S)이 우측방향으로 이동되는 것이다. In this process, since the steering roll 220 mounted on the inclined surface of the movable base 40 through the bearing block 41 is rotated counterclockwise in the drawing, the strip rolled leftward on the steering roll 220 ( S) is moved to the right direction.

이상에서 설명한 바와 같이 본 발명에 따른 소둔로내 진입 스트립 포지션 교정장치에 의하면, 루프카내로 유도되어진 스트립이 자체형상의 불량으로 인해 일방향으로 쏠리게 되는 경우 교정장치에 의해 자동교정되므로, 스트립의 에지부가 주변기기와 충돌하는 과정에서 발생하는 스트립손상 및 설비사고가 방지되어, 주변기기의 정비/수리에 따른 각종 부대비용이 절감될 뿐만 아니라 스트립의 제품품질이 향상되는 효과가 있는 것이다. As described above, in the annealing furnace entrance strip position correction apparatus according to the present invention, when the strip guided into the roof car is automatically corrected by the correction apparatus when it is oriented in one direction due to a defect in its own shape, the edge portion of the strip Strip damage and equipment accidents that occur in the process of collision with the peripheral device is prevented, as well as reducing the various incidental costs due to the maintenance / repair of the peripheral device as well as the effect of improving the product quality of the strip.
