본 발명은 배치식 소둔로의 인너커버 오일 씰링장치에 관한 것으로, 보다 상세하게는 인너커버의 국부적인 가열에 의한 열팽창과, 그로 인한 열변형에 따른 씰링불량을 방지하도록 개선된 배치식 소둔로의 인너커버 오일 씰링장치에 관한 것이다.The present invention relates to an inner cover oil sealing apparatus of a batch annealing furnace, and more particularly, to an improved batch annealing furnace to prevent thermal expansion due to local heating of an inner cover and a sealing failure caused by thermal deformation. An inner cover oil sealing device.

일반적으로, 배치 소둔로는 그 내부에 소재 코일을 다단으로 적치해 두고 분위기 가스의 열대류를 이용하여 소둔 처리하도록 구성된다.In general, the batch annealing furnace is configured to stack material coils in multiple stages therein and to perform annealing using tropical flow of atmospheric gas.

즉, 도 1에 도시된 바와 같이, 배치 소둔로는 다수의 코일(C)들이 다단으로 적치되고 수소 분위기 가스가 충진되어 있는 인너커버(1), 이 인너커버(1)의 외측에 일정한 공간(S)을 유지하고 있는 아웃커버(3), 이 아웃커버(3)에 설치되어 상기 공간(S)에 열을 발생시키는 버너(5), 이 버너(5)에서 발생되어 인너커버(1)의 내부로 전달되는 열에 의한 대류 현상을 증가시키는 팬(7)으로 구성된다.That is, as shown in FIG. 1, the batch annealing furnace has an inner cover 1 in which a plurality of coils C are stacked in multiple stages and filled with a hydrogen atmosphere gas, and a constant space outside the inner cover 1. An outer cover 3 holding S), a burner 5 installed in the outer cover 3 to generate heat in the space S, and a burner 5 generated in the burner 5, It consists of a fan 7 which increases the convection phenomenon by heat transferred to the inside.

그리하여, 버너(5)에서 발생된 열에 의한 대류로 인너커버(1) 안에 적치되고, 원형베이스(17)에 안착되어 있는 코일(C)들 소둔 처리하게 되며, 가열시킨 열 은 퍼니스연통(13)을 통해 스택통로(15)를 거쳐 스택으로 배출된다.Thus, the coils C which are deposited in the inner cover 1 by the convection caused by the heat generated by the burner 5 and are seated on the circular base 17 are annealed, and the heated heat is passed through the furnace communication 13. Through the stack passage 15 is discharged to the stack through.

그러나, 이러한 구조의 배치 소둔로는 팬(7)이 구비되고 인너커버(1)가 설치되는 원형 베이스(17)가 고정되어 있어 버너(5)의 불꽃이 인너커버(1)의 일측에만 집중적으로 작용하게 되므로 이 부분(19)이 쉽게 변형되어 인너커버(1)의 교체 주기를 짧게 하여 생산 원가를 상승시키고, 인너커버(1)의 교체 지연 시에는 코일(C)의 재질을 불균일하게 하여 제품의 품질을 저하시키게 된다.However, the arrangement annealing furnace of such a structure is provided with a fan 7 and a circular base 17 on which the inner cover 1 is installed is fixed so that the flame of the burner 5 concentrates only on one side of the inner cover 1.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

도 2는 본 발명에 따른 인너커버 오일 씰링장치의 설치상태도이고, 도 3은 본 발명에 따른 인너커버 오일 씰링장치의 요부 단면도이며, 도 4는 본 발명에 따 른 인너커버 오일 씰링장치의 요부 사시도이다.Figure 2 is an installation state of the inner cover oil sealing device according to the invention, Figure 3 is a sectional view of the main portion of the inner cover oil sealing device according to the invention, Figure 4 is a perspective view of the main part of the inner cover oil sealing device according to the present invention to be.

도 2 내지 도 4에 도시된 바와 같이, 본 발명에 따른 인너커버 오일 씰링장치는 코일(C)이 안착되는 원형베이스(100)의 테두리를 따라 혹은 이 테두리에 결합되도록 형성된 댐(Dam)(200)을 포함한다.As shown in Figures 2 to 4, the inner cover oil sealing device according to the present invention is a dam (200) formed along the edge of the circular base 100 on which the coil (C) is seated or coupled to the edge (Dam) 200 ).

상기 댐(200)은 도 3의 단면도에서와 같이, 저유홈(210)을 구성하며, 상기 저유홈(210) 즉, 상기 댐(200) 내부에는 씰링용 오일(300)이 저유된다.As shown in the cross-sectional view of FIG. 3, the dam 200 constitutes a storage groove 210, and the sealing oil 300 is stored in the storage groove 210, that is, the dam 200.

아울러, 인너커버(110)의 하단은 상기 씰링용 오일(300)에 일부 잠기도록 설치되는데, 이를 위해 도 2에서와 같이, 상기 인터커버(110)의 상단은 고정로드(400)에 의해 퍼니스연통(500)상에 해체 가능하게 클램핑된다.In addition, the lower end of the inner cover 110 is installed to be partially immersed in the sealing oil 300, for this purpose, as shown in Figure 2, the upper end of the intercover 110 is the furnace communication by the fixing rod 400 It is clampably dismountable on 500.

따라서, 상기 인너커버(110)의 하단은 상기 저유홈(210)에서 그 바닥면과 접촉되지 않고 들떠 있는 상태로 배치되게 되며, 버너(500)에 의해 열을 받아 열팽창이 일어날 경우 그 열팽창 정도(D)는 상기 인너커버(110)의 하단과 저유홈(210)의 바닥 사이의 유격내에서 충분히 수용될 수 있게 되므로 상기 인너커버(110)의 변형이 발생되지 않게 된다.Therefore, the lower end of the inner cover 110 is disposed in a state of floating in contact with the bottom surface in the oil reservoir 210, the thermal expansion degree when the thermal expansion occurs by the burner 500 ( D) can be sufficiently accommodated in the gap between the bottom of the inner cover 110 and the bottom of the oil reservoir 210 so that the deformation of the inner cover 110 does not occur.

뿐만 아니라, 상기 씰링용 오일(300)이 열에 의해 소모되는 것을 보충하기 위해 상기 저유홈(210)은 도 4와 같은 형태로 씰링용 오일탱크(700)와 연결된다.In addition, the oil reservoir 210 is connected to the sealing oil tank 700 in the form as shown in FIG. 4 in order to compensate that the sealing oil 300 is consumed by heat.

즉, 도 4와 같이, 댐(200)의 일부에는 상기 저유홈(210)과 연통되는 배출관(710)이 씰링용 오일탱크(700)와 연결되고, 다른 쪽에는 상기 씰링용 오일탱크(700)의 하측과 상기 저유홈(210)간을 서로 연결하되 오일펌프(720)를 통해 연결되는 공급관(730)이 구비된다.That is, as shown in Figure 4, a portion of the dam 200, the discharge pipe 710 communicating with the oil reservoir 210 is connected to the sealing oil tank 700, the other side of the sealing oil tank 700 The supply side 730 is connected to each other between the lower side and the oil reservoir 210 is connected via an oil pump 720.

따라서, 상기 저유홈(210)내 오일이 부족하지 않도록 상기 펌프(720)는 지속적으로 가동되며, 상세히 도시 하지는 않았으나 상기 저유홈(210)내에는 상기 펌프(720)의 가동을 제어하기 위한 수위검출센서(미도시)가 설치된다.Therefore, the pump 720 is continuously operated so that the oil in the reservoir groove 210 is not insufficient. Although not shown in detail, the water level detection for controlling the operation of the pump 720 is performed in the reservoir groove 210. A sensor (not shown) is installed.

아울러, 상기 저유홈(210)으로 공급되는 씰링용 오일(300)이 과다할 경우 이를 자동 배출시키는 오버플로우관(740)이 상기 배출관(710) 혹은 공급관(730)과 겸하여 병설된다.In addition, an overflow pipe 740 for automatically discharging the sealing oil 300 supplied to the storage oil groove 210 is provided in parallel with the discharge pipe 710 or the supply pipe 730.

이러한 구성으로 이루어진 본 발명 인너커버 오일 씰링장치는 상술한 오일펌프(720)에 의해 저유홈(210) 내부에 씰링용 오일(300)이 상시 채워져 있고, 인너커버(110)의 하단이 일부만 잠기도록 설치되어 있어 버너(600)의 직접 가열에 의한 열팽창시에도 인너커버(110)의 하단 변형이 저유홈(210) 내부에서 늘어났다 줄어들었다하면서 충분히 수용되므로 해당 부위의 변형이 제거된다.The inner cover oil sealing device of the present invention having such a configuration is always filled with a sealing oil 300 inside the oil storage groove 210 by the above-described oil pump 720, so that only the bottom of the inner cover 110 is partially locked. Since the bottom deformation of the inner cover 110 is increased and decreased inside the oil storage groove 210 even when thermal expansion is performed by the direct heating of the burner 600, the deformation of the corresponding part is removed.

따라서, 소둔로의 씰링상태는 양호하게 되어 분위기가스인 수소가스의 리크가 방지되고, 그로 인한 폭발의 위험성도 없어지게 되며, 소둔로 내부의 열 보전이 완벽하므로 보다 고품질의 제품을 생산할 수 있게 된다.Therefore, the sealing state of the annealing furnace is good to prevent the leakage of hydrogen gas, which is an atmosphere gas, the risk of explosion is also eliminated, and the heat preservation inside the annealing furnace is perfect, it is possible to produce a higher quality product. .
