소둔로의 외부커버 지지장치{Outcover suppoting apparatus of annealing furnace}Outcover suppoting apparatus of annealing furnace

본 발명은 배취(batch)형 고온수소 소둔을 수행하는 소둔로의 외부커버 지지장치에 관한 것으로서, 더욱 상세하게는 코일을 고온수소를 이용하여 소둔하기 위하여 소둔로의 외측에 외부커버를 결합함에 따라 상기 소둔로의 기밀능력을 증가시키는 한편, 소둔로의 내부에 안착된 코일의 측면을 지지하여 코일이 변형되는 것을 방지할 수 있는 소둔로의 외부커버 지지장치에 관한 것이다.The present invention relates to a device for supporting an outer cover of an annealing furnace that performs a batch hot hydrogen annealing, and more particularly, by combining an outer cover to the outside of the annealing furnace to anneaize the coil using high temperature hydrogen. The present invention relates to an apparatus for supporting an outer cover of an annealing furnace that can increase the airtight capacity of the annealing furnace and prevent the coil from being deformed by supporting the side of the coil seated inside the annealing furnace.

일반적으로 철강제품은 내부 응력제거와 일 방향 조직 형성을 위하여 적당한 온도로 가열 유지한 후 서냉하는 소둔과정을 수행하고 있으며 상기 소둔과정은 사용되는 노의 종류나 재료의 취급 방법에 따라 가스소둔로, 전기소둔로, 배치식 가스소둔로 등으로 구분된다.In general, steel products are subjected to annealing process in which the steel product is heated and maintained at an appropriate temperature to remove internal stress and unidirectional tissue formation. The annealing process is a gas annealing furnace according to the type of furnace used or the material handling method. Electric annealing furnace, batch gas annealing furnace, etc. are classified.

도 1은 배치식 가스소둔로를 나타낸 것으로서, 베이스(1)의 상면에 복수개의 코일(C)을 적재하고 그 코일(C)의 외측에는 코일(C)과 소정의 간격을 유지하면서 코일(C)을 감싸도록 내부커버(2)가 안착되며 상기 내부커버(2)의 외측에는 내부커버(2)와 소정의 간격을 유지하면서 내부커버(2)를 감싸도록 외부커버(3)가 설치되어 있다.1 shows a batch type gas annealing furnace, in which a plurality of coils C are mounted on an upper surface of the base 1 and a coil C is maintained on the outside of the coil C while maintaining a predetermined distance from the coil C. FIG. The inner cover 2 is seated so as to surround the inner cover 2, and the outer cover 3 is installed on the outer side of the inner cover 2 to surround the inner cover 2 while maintaining a predetermined distance from the inner cover 2. .

상기 외부커버(3)의 외측 둘레면 양측에는 지지바(4)가 설치되어 있고 그 지지바(4)의 단부에는 가이드홀더(5)가 설치되어 있다.Support bars 4 are provided at both sides of the outer circumferential surface of the outer cover 3, and guide holders 5 are provided at ends of the support bars 4.

한편, 상기 베이스(1)의 양측에는 가이드홀더(5)에 끼워지는 지지축(6)이 각각 설치되어 있다.On the other hand, support shafts 6 fitted to the guide holders 5 are provided on both sides of the base 1, respectively.

따라서 소둔과정을 수행하기 위해서는 베이스(1)의 상면에 복수개(3개)의 코일(C)을 적재시킨 후 그 코일(C)의 외측에 내부커버(2)를 씌운다.Therefore, in order to perform the annealing process, a plurality of (3) coils C are loaded on the upper surface of the base 1, and the inner cover 2 is covered on the outside of the coil C.

그리고 상기 내부커버(2)의 외측에는 외부커버(3)를 씌우되, 상기 외부커버(3)를 씌울 때에는 외부커버(3)의 외측 둘레면 양측에 설치된 지지바(4)의 단부에 고정된 가이드홀더(5)에 베이스(1)의 양측에 설치된 지지축(6)이 삽입되도록 한다.The outer cover 3 is covered by an outer side of the inner cover 2, and when the outer cover 3 is covered by the outer cover 3, the outer cover 3 is fixed to an end of the support bar 4 provided at both sides of the outer circumferential surface of the outer cover 3. The support shafts 6 installed on both sides of the base 1 are inserted into the guide holder 5.

이러한 상태에서 내부커버(2)에 분위기 가스를 공급하고 고온으로 가열시키면서 소둔과정을 수행하는 것이다.In this state, the annealing process is performed while supplying an atmosphere gas to the inner cover 2 and heating it to a high temperature.

그러나 이러한 종래의 소둔로는 고온소둔시 외부커버(3)의 하단부가 열변형으로 인하여 실링력이 저하되어 그 하단부를 통하여 외부 공기가 유입되어 품질을 저하시키는 문제점이 있었다.However, such a conventional annealing furnace has a problem in that the lower end portion of the outer cover (3) during the high temperature annealing, the sealing force is lowered due to heat deformation, so that the outside air flows through the lower end portion to deteriorate the quality.

또한 코일(C)의 적층이 불량인 상태에서 고온소둔을 수행 할 경우에는 코일(C)에 열변형이 발생되어 상기 코일(C)이 추락하면 내부커버(2) 및 외부커버(3)가 넘어지게 된다.In addition, when high temperature annealing is performed in a state in which the lamination of the coils C is poor, thermal deformation occurs in the coils C. When the coils C fall, the inner cover 2 and the outer cover 3 fall over. You lose.

상기 외부커버(3)가 넘어질 경우에는 그 외부커버(3)의 양측에 설치된 지지바(4)가 지지하므로 어느 정도는 지지할 수 있지만 상기 외부커버(3)가 넘어지는 것을 근본적으로 해결하지는 못하였다.When the outer cover 3 falls, the support bars 4 installed on both sides of the outer cover 3 can support it to some extent, but it does not fundamentally solve the fall of the outer cover 3. I couldn't.

본 발명은 상기한 문제점 해결하기 위하여 발명한 것으로서, 그 목적은 외부커버를 결합할 때 그 외부커버를 지지하는 지지축을 회전시키고 그 회전력을 이용하여 외부커버(3)의 하단부를 지지하는 지지블럭을 이동시켜 상기 외부커버 하단부의 열변형을 방지하는 한편, 코일의 적층불량으로 인한 추락발생시 안전사고를 방지할 수 있는 소둔로의 외부커버 지지장치를 제공함에 있다.The present invention has been invented to solve the above problems, the object is to rotate the support shaft for supporting the outer cover when the outer cover is coupled to the support block for supporting the lower end of the outer cover (3) by using the rotational force The present invention provides a device for supporting an outer cover of an annealing furnace that prevents thermal deformation of the lower end of the outer cover and prevents a safety accident in case of a fall due to a poor stacking of coils.

이와 같이 구성된 본 발명의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.

먼저, 소둔과정을 수행하기 위해서 베이스(1)의 상면에 복수개(3개)의 코일(C)을 적재시킨 후 그 코일(C)의 외측에 내부커버(2)를 씌운다.First, in order to perform the annealing process, a plurality of (3) coils C are loaded on the upper surface of the base 1, and then the inner cover 2 is covered on the outside of the coil C.

그리고 상기 내부커버(2)의 외측에는 외부커버(3)를 씌우되, 상기 외부커버(3)를 씌울 때에는 외부커버(3)의 외측 둘레면 양측에 설치된 지지바(4)의 단부에 고정된 가이드홀더(5)가 지지축(6)에 삽입되도록 한다.The outer cover 3 is covered by an outer side of the inner cover 2, and when the outer cover 3 is covered by the outer cover 3, the outer cover 3 is fixed to an end of the support bar 4 provided at both sides of the outer circumferential surface of the outer cover 3. The guide holder 5 is inserted into the support shaft 6.

이와 같이 가이드홀더(5)가 지지축(6)에 삽입되면 상기 가이드홀더(5)에 형성된 걸림돌기(5a)는 지지축(6)에 형성된 회전홈(6a)의 내부로 삽입되므로 상기 가이드홀더(5)가 하강하게 되면 회전홈(6a)은 나선방향으로 회전되면서 걸림돌기(5a)를 안내하게 되므로 상기 회전홈(6a)이 형성된 지지축(6)을 고정축(7)을 중심으로 회전하게 된다.As such, when the guide holder 5 is inserted into the support shaft 6, the locking protrusion 5a formed in the guide holder 5 is inserted into the rotary groove 6a formed in the support shaft 6, so that the guide holder 5 is inserted into the support shaft 6. When 5 is lowered, the rotary groove 6a rotates in a helical direction to guide the locking protrusion 5a, thereby rotating the support shaft 6 on which the rotary groove 6a is formed about the fixed shaft 7. Done.

상기 지지축(6)이 회전하게 되면 그 하부에 형성된 구동피니언기어(8)가 함께 회전하게되고 그 구동피니언기어(8)에 기어 결합된 구동랙기어(9)는 직선운동을 하게 되므로 상기 구동랙기어(9)가 형성된 작동바(10)는 지지블럭(11)에서 인출된다.When the support shaft 6 rotates, the drive pinion gear 8 formed at the lower side thereof rotates together, and the drive rack gear 9 geared to the drive pinion gear 8 is linearly moved. The operation bar 10 in which the rack gear 9 is formed is drawn out from the support block 11.

상기 작동바(10)가 인출되면 그 타측이 결합된 회전부재(12)가 회전하게 되고 이때 회전부재(12)의 내부에 내장된 태엽(14)은 복원력이 발생하게 되며 사익 회전부재(12)의 외측 둘레면에 형성된 종동피니언기어(13)가 함께 회전하게 된다.When the operation bar 10 is drawn out, the rotating member 12 coupled to the other side rotates. At this time, the spring 14 built into the rotating member 12 generates a restoring force. The driven pinion gear 13 formed on the outer circumferential surface of the is rotated together.

상기 종동피니언기어(13)가 회전하게 되면 그 종동피니언기어(13)에 기어 결합되어 있는 종동랙기어(15)가 직선방향 즉, 외부커버(3)측으로 이동하게 되므로 상기 종동랙기어(15)가 형성된 이동부재(16)는 외부커버(3)측으로 이동되는 것이다.When the driven pinion gear 13 rotates, the driven rack gear 15 geared to the driven pinion gear 13 is moved in a linear direction, that is, the outer cover 3 side, so that the driven rack gear 15 Is formed moving member 16 is to be moved to the outer cover (3) side.

상기 이동부재(16)가 외부커버(3)측으로 이동되면 그 이동부재(16)의 전방에 형성된 만곡홈(16a)은 외부커버(3)의 외측 둘레면에 긴밀히 접촉되면서 상기 외부커버(3)를 지지하게 되는 것이다.When the movable member 16 is moved to the outer cover 3 side, the curved groove 16a formed in front of the movable member 16 is in intimate contact with the outer circumferential surface of the outer cover 3 and the outer cover 3. Will be supported.

이러한 상태에서 내부커버(2)에 분위기 가스를 공급하고 고온으로 가열시키면서 소둔과정을 수행하는 것이다.In this state, the annealing process is performed while supplying an atmosphere gas to the inner cover 2 and heating it to a high temperature.

따라서 상기 외부커버(3)의 외측에는 이동부재(16)가 긴밀히 접촉되어 있으므로 고온소둔시 외부커버(3)의 하단부가 열변형되는 것을 방지하게 된다.Therefore, since the movable member 16 is in close contact with the outside of the outer cover 3, the lower end of the outer cover 3 is prevented from being thermally deformed during high temperature annealing.

또한 코일(C)이 내부커버(2)의 내측에서 열변형으로 인한 추락이 발생되어도 상기 외부커버(3)는 지지바(4) 및 이동부재(16)에 의해서 지지되어 있으므로 넘어지지 않는 것이다.In addition, even if the coil C falls due to heat deformation inside the inner cover 2, the outer cover 3 is supported by the support bar 4 and the moving member 16, so that the fall does not fall.

그리고 상기 소둔과정이 완료된 후 외부커버(3)를 상부로 상승시키면 지지축(6)이 역방향으로 회전되면서 이동부재(16)를 외부커버(3)에서 분리시키는 것이며 상기 이동부재는 회전부재(12)에 내장된 태엽(14)의 복원력에 의해서 더욱 안정적으로 분리되는 것이다.After the annealing process is completed, when the outer cover 3 is raised upward, the support shaft 6 is rotated in the reverse direction to separate the movable member 16 from the outer cover 3, and the movable member is the rotary member 12. It is to be separated more stably by the restoring force of the mainspring (14) built in.

이와 같은 본 발명은 외부커버가 하강함에 따라 이동부재가 이동되어 상기외부커버의 하부 양 측면을 지지하게 되므로 열변형에 의한 불량품 생산을 미연에 방지할 수 있음은 물론 적층된 코일이 추락시 외부커버가 넘어지는 것을 방지할 수 있는 특유의 효과가 있다.In the present invention as the outer cover is lowered the moving member is moved to support both sides of the lower side of the outer cover can prevent the production of defective products due to thermal deformation in advance, as well as the outer coil when the stacked coil falls There is a unique effect that can prevent the fall.
