본 고안은 스트립의 덴트 발생 방지를 위한 조질압연기에서의 이물질 제거장치에 관한 것으로서, 더욱 상세하게는 냉연강판 생산공정 중 연속소둔라인(Continuous Annealing Line, CAL)에서 생산된 스트립(Strip)의 항복점 연신을 방지하고 형상을 교정하며 조도를 부여하기 위한 조질압연기(Skin Pass Mill)에 퇴적되어 스트립에 덴트(Dent) 결함을 유발하는 이물질을 안티 클림핑롤과 스트립으 로부터 효과적으로 제거할 수 있도록 한 장치에 관한 것이다.The present invention relates to an apparatus for removing foreign substances in a temper rolling mill to prevent dent generation of strips, and more specifically, yield point stretching of strips produced in a continuous annealing line (CAL) during a cold rolled steel sheet production process. Of devices that can be effectively removed from anti-climping rolls and strips that have been deposited in Skin Pass Mills to prevent, correct, and provide roughness. will be.
연속소둔라인의 조질압연기(Skin Pass Mill)에는 이 조질압연기로 이송되는 스트립에 일정한 장력을 가하여 스트립의 사행 방지 및 구김에 의한 주름방지를 위한 안티 클림핑롤(Anti Crimping Roll)이 그 입측 및 출측에 설치되어 있다.The skin pass mill of the continuous annealing line is subjected to a constant tension on the strip conveyed by the temper rolling mill so that an anti-crimping roll is applied to the entry and exit of the strip to prevent meandering and creases by crease. It is installed.
상기 조질압연기가 가동되는 동안에는 수분을 포함한 이물질 및 스트립으로부터 발생된 이물질 등이 조질압연기의 롤(Roll)에 부착된다. 이러한 이물질이 조질압연기의 롤에 퇴적되면, 스트립에 덴트 결함을 유발하기 때문에 이러한 이 물질을 제거하기 위하여 종래에는 상기 조질압연기에서 스트립에 직접적으로 압하력을 가하는 작업롤(Work Roll)에 에어블로윙(Air Blowing) 장치가 설치되어 있으나, 이 에어블로윙 장치를 통해서 조질압연기로부터 이물질을 완전히 제거하는 데에는 무리가 있었다.During the operation of the temper mill, foreign substances including moisture and foreign substances generated from the strip are attached to the roll of the temper mill. When the foreign matter is deposited on the roll of the roughing mill, it causes a dent defect on the strip, so in order to remove such foreign matter, air blowing (work blowing) to the work roll that directly presses the strip in the conventional mill directly Air Blowing) was installed, but it was difficult to completely remove foreign matter from the temper mill through this air blowing device.
또한, 상기 조질압연기는 그 내부가 매우 협소하기 때문에 종래에는 조질압연기의 이물질을 제거하기 위하여 조질압연기의 작업롤(Work Roll) 및 중간롤(Intermediate Roll)을 모두 인출한 후 작업자가 들어가서 수작업을 통해 이물질을 제거해야만 했다. In addition, since the inside of the temper rolling mill is very narrow, conventionally, after removing both the work roll and the intermediate roll of the temper mill in order to remove the foreign matter of the temper rolling mill, the worker enters through a manual operation. Foreign material had to be removed.
따라서, 조질압연기로부터 이물질을 제거하는 데 많은 시간이 소요되고, 또한 라인 속도(Line Speed) 저하로 인해 생산성이 감소되는 문제점이 있었다.Therefore, it takes a long time to remove the foreign matter from the temper mill, and also there is a problem that the productivity is reduced due to a decrease in the line speed (Line Speed).
따라서, 상술한 바와 같은 종래의 문제점을 해결하기 위하여, 본 고안은 조질압연기의 작업롤에 설치된 종래의 에어블로윙 장치 이외에 안티 클림핑롤을 세척할 수 있는 세척장치 및 스트립의 양 가장자리부를 세척할 수 있는 세척장치를 더 구비하여 조질압연기에 이물질이 유입되는 것을 완전히 차단함으로써 조질압연기에 퇴적되는 이물질로 인해 스트립의 표면에 덴트(Dent)와 같은 불량이 발생되지 않도록 하는데 그 목적이 있다.Therefore, in order to solve the conventional problems as described above, the present invention is capable of cleaning both edges of the strip and the cleaning device capable of cleaning the anti-climping roll in addition to the conventional air blowing device installed on the work roll of the temper mill. A further cleaning device is provided to completely prevent foreign substances from flowing into the rough mill so that defects such as dents do not occur on the surface of the strip due to the foreign matter deposited on the rough mill.
상기 목적은, 조질압연기의 입측에 설치되는 안티 클림핑롤의 하측에 분사공이 다수 형성되는 세척배관이 설치되고 이 세척배관은 에어 공급배관 및 워터 공급배관과 연결되며, 상기 세척배관의 하측에는 이물받이가 구비되고, 스트립 출측 권취기와 상기 안티 클림핑롤 사이에는 스트립의 양 가장자리부를 세척하기 위한 엣지 에어블로윙(Edge Air Blowing) 장치가 스트립을 중심으로 상하 대칭적으로 설치되는 것을 특징으로 하는 스트립의 덴트 발생 방지를 위한 조질압연기에서의 이물질 제거장치에 의해 달성된다.The object is, the washing pipe is provided with a plurality of injection holes are formed in the lower side of the anti-climping roll is installed on the mouth of the temper mill, the cleaning pipe is connected to the air supply pipe and water supply pipe, the lower side of the cleaning pipe is a foreign matter receiving Is provided, and an edge air blowing device for cleaning both edge portions of the strip between the strip winding machine and the anti-climping roll is dent generation of the strip, characterized in that it is installed symmetrically around the strip Achieved by a debris removal device in the temper mill for prevention.
이하에서, 첨부도면을 참조하여 본 고안의 구성을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention.
본 고안상의 스트립의 덴트 발생 방지를 위한 조질압연기에서의 이물질 제거장치는, 도 2 및 도 3에서 보는 바와 같이, 4단 또는 6단으로 1 ~ 2 스탠드 설치되고 이 스탠드의 전후측에는 스트립을 안내하는 안티 클림핑롤이 설치되며, 상기 스 탠드에 구비된 한 쌍의 작업롤 사이를 통과하는 스트립으로부터 이물질을 세척하기 위한 에어블로윙 장치가 설치되는 조질압연기에 있어서, The foreign material removal apparatus in the temper mill for preventing the dent generation of the strip according to the present invention, as shown in Figures 2 and 3, 1 to 2 stands are installed in four or six stages and the front and rear sides of the stand to guide the strips. In the temper rolling mill is provided with an anti-climping roll is installed, the air blowing device for cleaning the foreign matter from the strip passing between the pair of work rolls provided in the stand,
상기 조질압연기의 입측에 설치되는 안티 클림핑롤의 하측에는 분사공이 다수 형성되는 세척배관이 설치되고 이 세척배관은 에어 공급배관 및 워터 공급배관과 연결된다.A washing pipe having a plurality of injection holes is installed at the lower side of the anti-climping roll installed at the mouth of the temper mill, and the washing pipe is connected to the air supply pipe and the water supply pipe.
또한, 상기 세척배관의 하측에는 이물받이가 구비된다.In addition, a drip tray is provided below the washing pipe.
한편, 스트립 출측 권취기와 상기 안티 클림핑롤 사이에는 스트립의 양 가장자리부를 세척하기 위한 엣지 에어블로윙 장치가 스트립을 중심으로 상하 대칭적으로 설치된다.On the other hand, an edge air blowing device for cleaning both edges of the strip is installed symmetrically up and down about the strip between the strip exit winding machine and the anti-climping roll.
상기 엣지 에어블로윙 장치는 리드 스크류(Lead Screw)에 의해 좌우로 위치 이동이 가능하도록 구성된다.The edge air blowing device is configured to be movable in position from side to side by a lead screw.
이상과 같이 구성된 본 고안상의 스트립의 덴트 발생 방지를 위한 조질압연기에서의 이물질 제거장치에 의해서, 라인(Line)의 가동중에는 상기 에어 공급배관을 개방하여 상기 세척배관으로부터 에어를 분사토록 하여 안티 클림핑롤의 표면을 세척하고, 만일 이 안티 클림핑롤에 이물질이 묻어 스트립(Strip) 표면에 덴트(Dent)가 발생 시에는 에어 공급배관 대신 상기 워터 공급배관을 개방하여 상기 세척배관으로부터 세척수를 분사토록 함으로써 안티 클림핑롤에 부착되어 있는 이물질들을 효과적으로 제거하여 이물질이 조질압연기로 유입되는 것을 방지할 수 있다.Anti-climping rolls by opening the air supply pipe to inject air from the cleaning pipe during the operation of the line by the foreign matter removal device in the temper mill to prevent the dent generation of the strip according to the present invention configured as described above If the surface of the anti-climping roll has a dent on the strip surface due to foreign matters, the water supply pipe is opened instead of an air supply pipe to spray the water from the cleaning pipe. By effectively removing the foreign matters attached to the crimping rolls, it is possible to prevent foreign matters from entering the temper mill.
또한, 스트립의 가장자리부에 부착될 수 있는 이물질은 리드 스크류(Lead Screw)를 통해 위치 조절이 가능한 상기 엣지 에어블로윙 장치를 이용하여 경제적이고도 효과적으로 제거할 수 있다.In addition, the foreign matter that can be attached to the edge of the strip can be economically and effectively removed by using the edge air blowing device that can be adjusted through the lead screw (Lead Screw).
여기서, 상기 리드 스크류(Lead Screw)는 스크류의 회전에 의해 이 스크류에 체결된 암나사가 이동되는 원리를 이용한 이동수단이다.Here, the lead screw is a moving means using the principle that the female screw fastened to the screw is moved by the rotation of the screw.
이상과 같은 본 고안에 의해서, 종래 조질압연기의 이물질 제거를 위한 작업 시의 문제점인 냉연강판 생산 공정에서의 라인 속도(Line Speed) 저하 및 조질압연기(Skin Pass Mill) 내에 있는 작업롤(Work Roll) 및 중간롤(Intermediate Roll)을 인출 후 작업자가 들어가 이물질을 제거해야 하는 등에 따른 번거로움을 해소할 수 있을 뿐 아니라 본 고안상의 수압 및 공압을 이용한 이물질 제거장치를 통해 냉연강판의 생산성 및 품질 향상 등의 경제적 효과를 얻을 수 있다.According to the present invention as described above, in the cold rolled steel sheet production process, which is a problem in the work for removing foreign matter of the conventional temper mill (Line Speed) lowering and the work roll (Work Roll) in the skin pass mill (Skin Pass Mill) And after removing the intermediate roll (Intermediate Roll) can not only solve the trouble of having to enter the worker to remove the foreign matter, but also to improve the productivity and quality of the cold rolled steel sheet through the foreign material removal device using the hydraulic and pneumatic pressure of the present invention The economic effect of
