본 고안은 조질 압연되는 열연코일 강판의 접힘을 방지하기 위한 조질압연기의 열연코일 강판 접힘방지 장치에 관한 것으로, 특히 조질압연기에서 열연코일 강판을 압연할 때에 열연코일 강판이 권취된 권취롤로부터 공급되는 열연코일 강판의 공급속도와 조질압연롤에서 압연되어 나가는 압연강판의 속도가 비례하지 않음으로 인하여 조질압연롤의 입측에서 열연코일 강판이 접힘이 발생하게 된다.The present invention relates to a device for preventing the folding of a hot rolled coil steel sheet of a temper rolling mill to prevent the folding of the hot rolled coil steel sheet to be rolled, in particular, when rolling the hot rolled coil steel sheet in the temper rolling mill is supplied from a winding roll wound Since the feed rate of the hot rolled coil steel sheet and the speed of the rolled steel sheet rolled out of the temper rolled steel are not proportional to each other, the hot rolled coil steel sheet is folded at the inlet side of the rolled steel roll.

따라서 상기와 같이 접힘이 발생한 열연코일 강판이 접힘이 발생한 상태 그대로 조질압연롤에 인입되는 것을 방지하기 위한 장치이다.Therefore, it is an apparatus for preventing the hot rolled coil steel sheet which has been folded as described above from being drawn into the temper roll as it is being folded.

종래의 압연기는 도면 제3도에서 도시된 바와같이 열연코일강판(60)이 권취된 권취롤(40)로부터 열연코일강판(60)을 풀어주어 핀치롤(30)을 통과하면서 아이들롤(50)의 안내를 받아 조질압연롤(20)에 인입되게 된다.Conventional rolling mill is to release the hot rolled coil steel sheet 60 from the winding roll 40 wound around the hot rolled coil steel sheet 60, as shown in Figure 3, passing through the pinch roll 30, idle roll 50 Received by the guide will be drawn into the temper roll (20).

이때 조질압연롤(20)로 인입된 열연코일강판(60)은 조질압연롤(20)로부터 압연이 이루어진다.In this case, the hot rolled coil steel sheet 60 drawn into the temper roll 20 is rolled from the temper roll 20.

따라서 상기 조질압연롤(20)에서는 열연코일강판(60)의 압연에 따라 열연코일강판(60)의 진행속도가 약간 죽으면서 권취롤(40)로부터 공급되는 열연코일강판(60)의 공급속도와 약간의 차이가 발생하게 된다.Therefore, in the tempered roll 20, the feed rate of the hot rolled coil steel sheet 60 is supplied from the take-up roll 40 while the rolling speed of the hot rolled coil steel sheet 60 slightly dies in accordance with the rolling of the hot rolled coil steel sheet 60 There will be a slight difference.

따라서 조질압연롤(20)의 입측에서는 조질압연롤(20)로부터 압연되어 나가는 열연압연강판(70)과 조질압연롤(20)로 공급되는 열연코일강판(60)의 속도차에 의하여 조질압연롤(20) 입측에서 열연코일강판(60)의 접힘이 발생하게 된다.Therefore, on the inlet side of the temper roll 20, the temper roll is rolled by the speed difference between the hot rolled steel sheet 70 rolled out of the temper roll roll 20 and the hot rolled coil steel sheet 60 supplied to the temper roll roll 20 (20) At the inlet side, the hot rolled coil steel sheet 60 is folded.

이와같이 접힘이 발생한 열연코일강판(60)은 접힘이 발생한 상태 그대로 조질압연롤(20)에 인입에 되어 압연을 실시하게 되고 이로 인하여 불량제품을 생산하게 됨은 물론 조질압연롤(20)의 훼손을 유발시키는 원인이 되었던 것이다.Thus, the hot rolled coil steel sheet 60 in which the folding occurs is drawn into the temper rolling roll 20 as it is folded and rolled, thereby producing a defective product, as well as causing damage to the temper rolling roll 20. It was the cause of letting.

본 고안의 상기와 같은 제반 문제점을 감안하여 이를 해소하고자 고안한 것으로 열연코일 강판이 조질압연롤에서 압연될때에 발생하는 열연코일 강판의 접힘 현상을 예방할 수 있도록 한 압연기의 열연코일 강판 접힘 방지장치를 제공함에 그 목적이 있는 것이다.It is designed to solve the problems in view of the above problems of the present invention to prevent the folding of the hot rolled coil steel sheet of the rolling mill to prevent the phenomena of the hot rolled coil steel sheet when the hot rolled coil steel sheet is rolled in the temper rolls The purpose is to provide.

열연코일강판(60)을 권취하는 권취롤(40)과 핀치롤(30) 및 아이들롤(50) 그리고 조질압연롤(20)을 순차적으로 설치하여서 된 통상의 압연장치에 있어서 상기 조질압연롤(20)과 아이들롤(50)의 사이에는 열연코일강판 접힘방지장치(10)를 설치하되 이 열연코일강판 접힘방지장치(10)의 구성은 상하부에 90각을 이루도록 상하부 벤딩롤(11)(12)의 양단부에는 상하부 벤딩롤(11)(12)이 일체가 되도록 브라켓트(14)를 이용하여 설치하였으며, 상기 90각을 이루는 상하부 벤딩롤(11)(12)의 90지점에는 밸런스바(13)를 설치하였고 이 밸런스바(13)의 양단부에는 스윙암(15)을 설치하되 상기 스윙암(15)은 유압실린더(16)의 실린더로드(17)에 형성된 체결구(18)를 이용하여 설치하여서 된 것이다.In the conventional rolling apparatus in which the winding roll 40, the pinch roll 30, the idle roll 50, and the rough rolling roll 20 which wind the hot rolled coil steel sheet 60 are sequentially installed, said rough rolling roll ( The hot rolled coil steel sheet folding prevention device 10 is installed between 20) and the idle roll 50, but the configuration of the hot rolled coil steel sheet folding prevention device 10 is 90 to the bottom Phase to angle At both ends of the lower bending rolls 11 and 12, The lower bending rolls 11 and 12 were installed using the bracket 14 so as to be integrated, and the 90 An angled image 90 of the lower bending rolls 11 and 12 A balance bar 13 is installed at the point, and swing arms 15 are installed at both ends of the balance bar 13, but the swing arm 15 is fastened to the cylinder rod 17 of the hydraulic cylinder 16. 18) was installed by using.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안은 먼저 도면 제1도에서 도시된 바와같이 열연코일강판(60)이 권취된 권취롤(40)로부터 열연코일강판(60)을 핀치롤(30)을 통하여 아이들롤(50)과 하부벤딩롤(12)의 안내를 받으며 상하부에 위치한 조질압연롤(20)의 사이로 들어가 조질압연이 실시되게 되는데 이때 조질압연롤(20)은 열연코일강판(60)을 압연하기 때문에 열연코일강판(60)이 공급속도 보다 약간 늦어지게 된다.The present invention is first bending the hot rolled coil steel sheet 60 through the pinch roll 30 from the winding roll 40 wound around the hot rolled coil steel sheet 60 as shown in FIG. Guided by roll 12 The temper rolling is carried out between the temper rolling rolls 20 located in the lower part, wherein the temper rolling rolls 20 roll the hot rolled coil steel sheet 60 so that the hot rolled coil steel sheet 60 is slightly slower than the supply speed. .

따라서 조질압연롤(20)의 입측에서는 권취롤(40)로부터 공급되는 열연코일강판(60)의 조질압연롤(20)에서 압연되어 나가는 열연압연강판(70)의 진행속도차에 열연코일강판(60)이 접힘이 발생하게 된다.Therefore, at the entrance side of the tempered rolling roll 20, the hot rolled coil steel sheet (the hot rolled coil steel ( 60) this fold occurs.

이때 유압실린더(16)를 작동시켜 실린더로드(17)의 체결구(18)에 연결설치된 스윙암(15)을 밸런스바(13)를 중심축으로 회전시키게 되면 밸런스바(13)는 스윙암(15)의 회전과 함께 회전하면서 하부벤딩롤(12)을 도면 제2(a)도와 제2(b)도는 같이 순차적으로 들어 올려주어 열연코일강판(60)이 접힘되는 것을 방지함과 동시에 열연코일강판(60)을 평평하게 유지시켜 주는 것이다.At this time, if the swing arm 15 connected to the fastener 18 of the cylinder rod 17 is operated by operating the hydraulic cylinder 16, the balance bar 13 is rotated about the central axis. While rotating with the rotation of 15), the lower bending roll 12 is sequentially lifted as shown in FIGS. 2 (a) and 2 (b) to prevent the hot rolled coil steel sheet 60 from being folded and at the same time, the hot rolled coil. The steel sheet 60 is kept flat.

단, 상기 하부벤딩롤(12)이 상부로 들려질때에는 상부 벤딩롤(11)은 하방으로 내려오면서 아이들롤(50)과 수직을 이루게 되어 열연코일강판(60)의 원활한 공급을 도와주게 되는 것이다.However, when the lower bending roll 12 is lifted to the upper portion, the upper bending roll 11 is lowered to be perpendicular to the idle roll 50 to help smoothly supply the hot rolled coil steel sheet 60. .

또한 상기 상하부 벤딩롤(11)(12)과 밸런스바(13)는 좌우 양측 단부에 브라켓트(14)에 의하여 설치되어 있기 때문에 밸런스바(13)의 회동과 함께 상하부 벤딩롤(11)(12)이 일체로 움직이게 되는 것이다.Also the above phase The lower bending rolls 11 and 12 and the balance bar 13 are left Since the bracket 14 is installed at both ends of the right side, the balance bar 13 rotates and The lower bending rolls 11 and 12 are integrally moved.

한편 스윙암(15)을 작동시키는 유압실린더(16)는 실린더로드(17)가 스윙암(15)을 밀어줄때에 유압실린더(16)는 중심핀(19)을 중심으로 약간의 경사각을 갖도록 회전되게 된다.Meanwhile, the hydraulic cylinder 16 for operating the swing arm 15 rotates so that the hydraulic cylinder 16 has a slight inclination angle around the center pin 19 when the cylinder rod 17 pushes the swing arm 15. Will be.

이는 스윙암(15)의 회전반경을 감안하였기 때문이다.This is because the rotation radius of the swing arm 15 is considered.

또한 본 고안의 열연코일강판(60)이 제2(b)도와 같이 되어 접힘이 방지되었을 때에는 유압실린더(16)를 상기 열연코일강판(60)을 들어 줄때의 역동작으로 작동시켜 도면 제2(a)도에서 도면 제1도처럼 순차적으로 원상복귀 시킨다.In addition, when the hot rolled coil steel sheet 60 of the present invention becomes like the second (b) and the folding is prevented, the hydraulic cylinder 16 is operated in the reverse operation when the hot rolled coil steel sheet 60 is lifted. In Fig. 1), return to the original order sequentially as in Fig. 1.

이와같이 상하부 벤딩롤(11)(12)을 원상복귀 시키면 유압실린더(16)도 도면 제1도처럼 수평상태가 되는 것이다.In this way When the lower bending rolls 11 and 12 are returned to their original positions, the hydraulic cylinder 16 is also horizontal as shown in FIG. 1.

이상과 같은 본 고안은 열연코일 강판이 조질압연롤의 입측에서 발생하는 접힘현상을 방지할 수 있어 양질의 압연강판을 생산할 수 있음은 물론 조질압연롤의 훼손을 예방할 수 있어 조질압연롤의 수명을 연장할 수 있고 또한 생산성을 향상시킬 수 있는 유용한 고안인 것이다.The present invention as described above can prevent the phenomena occurring in the hot rolled coil steel sheet in the inlet side of the rolled steel rolls can produce a good quality rolled steel sheet, and can prevent the damage of the rolled steel rolls to improve the life of the rolled steel rolls. It is a useful design that can be extended and improves productivity.
