Description
본 발명은 스테인레스 냉연코일을 광휘소둔처리하기 위한 광휘소둔로에 관한 것으로, 더욱 상세하게는 소둔로의 인렛트의 댄스롤에 묻은 이물질에 의해 스트립이 쏠리는 것을 방지할 수 있도록 광휘소둔로의 댄스롤 표면 이물질 제거장치에 관한 것이다.The present invention relates to a bright annealing furnace for bright annealing a stainless cold rolled coil, and more particularly, to a dance roll of a bright annealing furnace to prevent the strip from being swayed by foreign matter on the dance roll of the inlet of the annealing furnace. It relates to a surface foreign matter removal device.
일반적으로 광휘소둔은 냉간 압연된 스트립을 소재로 강 표면에 산화탈탄을 막고 금속적 광택을 잃지 않도록 환원성이나 비산화성 가스의 기류 내에서 소둔을 행하는 것으로, 소둔 후에 그대로 냉각하면 표면의 광택은 상실되지 않고 처음 그대로를 유지하는 특성이 있다.In general, bright annealing is a cold rolled strip that prevents decarburization on the surface of the steel and is annealed in a stream of reducing or non-oxidizing gas so as not to lose metallic luster. There is a characteristic that keeps it as it is.
통상 광휘소둔은 열처리 중에 발생되는 산화와 광택도 저하를 방지하기 위해 분위기 가스인 수소를 사용하게 되는 데, 수소의 유출을 방지하기 위해 광휘소둔로는 스트립의 입측과 출측이 밀폐되어 있는 진공로를 사용하게 된다.In general, bright annealing uses hydrogen, an atmospheric gas, to prevent oxidation and glossiness, which are generated during heat treatment. In order to prevent the outflow of hydrogen, the bright annealing furnace uses a vacuum furnace in which the inlet and the outlet of the strip are sealed. Will be used.
도 1은 일반적인 광휘소둔로를 도시한 도면으로, 가열로(100) 하부의 밀폐박스(101)로 투입되는 스트립(150)은 밀폐박스 내부에 설치된 댄스롤(110)을 거쳐 본체 가열로(100) 상부에 설치된 냉각대(102)를 지나게 되고 상부의 가이드롤(103)을 거쳐 수직으로 설치된 리턴덕트(104) 내부를 통하여 밑으로 빠져나오는 구조로 되어 있다. 또한 스트립(150)을 수직으로 이송시키는 과정에서 스트립(150)에 최소장력을 유지시키기 위해 상기 댄스롤(110)에는 하강 텐션을 가하게 된다.1 is a view showing a general bright annealing furnace, the strip 150 is introduced into the sealed box 101 of the lower portion of the heating furnace 100 through the dance roll 110 installed in the sealed box body heating furnace 100 Pass through the cooling stand 102 installed in the upper portion and through the inside of the return duct 104 installed vertically through the guide roll 103 of the upper portion is configured to exit. In addition, a downward tension is applied to the dance roll 110 in order to maintain the minimum tension on the strip 150 during the vertical transfer of the strip 150.
상기 댄스롤은 알루미늄재질로 이루어지며 스트립의 미세 텐션을 가하는 역할을 하게되어 소량의 이물질이 표면에 묻은 경우 이 이물질에 의해 스트립의 쏠림이 발생된다.The dance roll is made of aluminum and serves to apply a fine tension of the strip so that when a small amount of foreign matter is on the surface, the stripping of the strip is caused by this foreign matter.
스트립이 일측으로 쏠리게 되면 설비에 에지부가 접촉되고 스트립이 파단되는 현상이 발생하고, 슬립에 의해 롤 표면이 조기에 손상되는 문제점이 있다.If the strip is pulled to one side, the edge portion is contacted to the equipment and the strip is broken, and the roll surface is damaged early due to slip.
또한, 댄스롤 표면에 묻은 이물질은 스트립 표면에 이물 압입을 발생시킴에 따라 제품품질을 저하시키게 되며, 대량의 이물 압입이 발생할 경우에는 라인을 정지시키고 밀폐박스 또는 머풀 내의 가스를 제거하고 가열로 버너를 수화한 후 밀폐박스를 분해하여 댄스롤 표면에 묻은 이물질을 제거하게 되므로 작업이 어렵고 시간이 많이 소요되는 단점이 있다.In addition, foreign matters on the dance roll surface deteriorate the product quality by causing foreign material indentation on the strip surface.In the case of a large amount of foreign material indentation, the line is stopped, gas in the closed box or muffler is removed, and the burner is heated. After dehydrating the sealed box to remove foreign substances on the surface of the dance roll by disassembling the box is difficult and time-consuming disadvantages.
이에 본 발명은 상기와 같은 제반 문제점을 해결하기 위하여 안출된 것으로, 롤 표면에 이물질에 의한 결함 발생시 라인을 세우지 않고 댄스롤 표면에 묻은 이물질을 제거할 수 있도록 된 광휘소둔로의 댄스롤 표면 이물질 제거장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, remove the foreign matter of the dance roll surface of the bright annealing furnace that can remove the foreign matter on the surface of the dance roll without standing a line when a defect caused by foreign matter on the roll surface The object is to provide a device.
또한, 본 발명은 이물질 제거에 의해 스트립 쏠림을 바로 잡아줌으로써 스트립과 설비의 파손을 방지할 수 있도록 된 광휘소둔로의 댄스롤 표면 이물질 제거장치를 제공함에 또다른 목적이 있다.In addition, another object of the present invention is to provide an apparatus for removing foreign matter from the surface of a dance roll of a bright annealing furnace, which is capable of preventing damage to the strip and equipment by correcting strip stripping by removing foreign substances.

이하 본 발명의 작용에 대해 설명한다.Hereinafter will be described the operation of the present invention.
스트립(150)은 가열로(100) 하부의 밀폐박스(101) 입구를 통해 밀폐박스(101) 내부로 진입하여 댄스롤(110)을 거친 후 가열로(100)로 수직상승하여 진행하게 된다.The strip 150 enters the sealed box 101 through the inlet of the sealed box 101 under the heating furnace 100, passes through the dance roll 110, and then vertically rises to the heating furnace 100.
스트립(150) 진행도중 댄스롤(110)에 묻은 이물질에 의해 어느 한쪽으로 쏠림현상이 발생하게 되면, 댄스롤(110) 중심에서 스트립이 일측으로 미끄러지게 되고, 이렇게 일측으로 쏠린 스트립(150)은 밀폐도어(10)에 설치되어 있는 근접센서(11,12)에 감지된다.When the stripping phenomenon occurs on one side due to foreign matter on the dance roll 110 while the strip 150 is in progress, the strip is slid to one side from the center of the dance roll 110 and thus the strip 150 slid to one side is It is detected by the proximity sensors 11 and 12 installed in the sealed door 10.
예컨데, 스트립(150)이 우측으로 쏠리게 되면 밀폐도어(10)의 우측에 설치되어 있는 근접센서(12)에 스트립이 감지되고, 이 센서(12)의 감지신호에 따라 댄스롤(110) 표면의 이물질 제거작업이 개시된다.For example, when the strip 150 is pulled to the right side, the strip is detected by the proximity sensor 12 installed on the right side of the airtight door 10, and the strip of the surface of the dance roll 110 is detected according to the detection signal of the sensor 12. Foreign material removal work is started.
즉, 상기 근접센서(12)의 감지신호를 인가받은 컨트롤러는 공급관(41) 일측에 설치된 솔레노이드밸브(42)를 개방작동하고, 이와 동시에 지지바(20)에 설치된 가압실린더(21)를 신장작동시키게 된다.That is, the controller receiving the detection signal of the proximity sensor 12 opens the solenoid valve 42 installed on one side of the supply pipe 41, and simultaneously expands the pressure cylinder 21 installed on the support bar 20. Let's go.
공급관(41)이 개방됨에 따라 공급관(41)을 통해 밀폐박스(101) 내부로 연장된 분사관(40)으로 질소가스가 공급되어 댄스롤(110)과 댄스롤(110)을 거쳐 수직으로 상승하는 스트립 사이로 질소가스가 분사된다.As the supply pipe 41 is opened, nitrogen gas is supplied to the injection pipe 40 extending into the sealed box 101 through the supply pipe 41 and ascended vertically through the dance roll 110 and the dance roll 110. Nitrogen gas is injected between the strips.
이렇게 분사되는 질소가스에 의해 댄스롤(110) 표면에 묻어 있는 이물질이 일차 제거된다.Thus, foreign matters buried on the surface of the dance roll 110 are first removed by the nitrogen gas injected.
그리고 상기 가압실린더(21)의 신장작동에 따라 가압실린더(21)의 피스톤로드 선단에 설치되어 있는 팰트포(22)가 댄스롤(110)의 표면에 밀착된다.In addition, the felt cloth 22 installed at the tip of the piston rod of the pressure cylinder 21 is in close contact with the surface of the dance roll 110 according to the expansion operation of the pressure cylinder 21.
팰트포(22)가 댄스롤(110) 표면에 밀착된 상태에서 댄스롤(110)이 회전함으로써 댄스롤(110) 표면에 묻은 이물질은 팰트포(22)에 의해 닦여져 제거되는 것이다.As the dance roll 110 is rotated while the felt cloth 22 is in close contact with the surface of the dance roll 110, foreign matter on the surface of the dance roll 110 is wiped off by the felt cloth 22.
