Description

스트립 권취시 단차 마크 길이 저감 방법 및 이를 이용한 스트립Reduction of step mark length in strip winding and strip using same
본 발명은 스트립 권취시 단차 마크(end mark) 길이 저감 방법 및 이를 이용한 스트립에 관한 것으로서, 더욱 자세하게는, 스트립을 릴에 권취시 스트립의 내권부의 외주연에 종이로 덧대고, 릴에 스트립을 한 바퀴 감은 후 내권부의 단차부와 접촉할 부분의 외주연에 에어캡을 덧대어 스트립을 릴에 감으면, 스트립의 단차 마크 길이를 저감되는 효과를 가지는 기술에 관한 분야이다.The present invention relates to a method for reducing the end mark length during strip winding and a strip using the same. After winding one round, an air cap is applied to the outer periphery of the portion to be contacted with the step portion of the inner circumference, and the strip is wound on the reel.
스테인리스 냉연 제품을 생산하는 최종 공정은 평탄 라인(Tension Leveling Line)과 절단 라인(Slitting Line) 2개의 공정이 있다. 이들 공정에서는 코일을 평탄하게 레벨링하여 스트립(strip)의 양 사이드를 고객의 요구에 맞추어 폭을 셋팅(setting)한 후 연속작업을 하거나 스트립의 양 끝단을 연속해서 절단 작업 및 분할 작업을 한다.There are two final processes for producing cold rolled stainless steel products: tension leveling line and slitting line. In these processes, the coils are leveled flat to set width on both sides of the strip to meet the customer's requirements, followed by continuous operation, or cutting and dividing the ends of the strip continuously.
이들 공정 라인에서는 스트립의 출측에서 제품을 권취하는 과정을 가지는데, 스트립 초기 권취 작업시 스트립 소재가 1.5mm 이상의 후물재인 경우, 스트립의 단차부에서는 단차 마크가 발생하게 된다.These process lines have a process of winding the product on the exit side of the strip. When the strip material is a thick material of 1.5 mm or more during the initial winding operation of the strip, a step mark occurs at the step portion of the strip.
도 1은 권취된 스트립의 측면도(a)와, 스트립의 단차부(A)를 확대한 측면도(b)이다. 도 1(a)에 도시된 바와 같이 릴(1)에 스트립(2)이 권취되면, 한 바퀴 권취된 스트립(2) 부분 중 단차부(3)에 접촉하는 부분은 도 1(b)에 도시된 바와 같이 단차 마크(4)가 발생하게 된다.1 is a side view (a) of a wound strip and an enlarged side view (b) of a step (A) of the strip. When the strip 2 is wound on the reel 1 as shown in Fig. 1 (a), the portion of the strip 2 which is wound around the contacting step 3 is shown in Fig. 1 (b). As shown, the step mark 4 is generated.
도 2는 스트립의 권취시 단차부에서 단차 마크가 발생되는 과정을 도시한 측면도이다. 도 2에 도시된 바와 같이, 릴(1)에 권취되는 스트립(2)은 단차부(3)가 스트립(2)에 접촉하면서 스트립(2)은 꺽이는 현상(단차 마크)이 발생하게 된다(도 2(d)).2 is a side view illustrating a process of generating a step mark in the step part when the strip is wound. As shown in FIG. 2, the strip 2 wound on the reel 1 causes the strip 2 to be bent (step mark) while the step portion 3 contacts the strip 2 (FIG. 2 (d)).
단차 마크(4)는 스트립 완제품의 고질적인 결함으로서, 단차 마크(4) 길이는 후물, 연질, 내경이 작을수록 길어지며, 발생 피치(pitch)는 외권부로 갈수록 길어지지만 그 정도가 약해지다가 사라진다.The step mark 4 is a chronic defect of the finished product of the strip. The step mark 4 has a longer length, softer, and smaller inner diameter, and the pitch becomes longer toward the outer region, but becomes weaker and disappears. .
따라서, 스트립(2) 권취시에 단차 마크(4) 발생 길이를 저감시키기 위해, 스트립(2)의 내권부의 외주연에 골판지를 덧댄 후 스트립(2)을 권취하였으나, 이는 작업자의 숙련도 정도에 따라 발생하는 단차 마크(4)의 길이의 편차가 큰 문제점이 있었다. Therefore, in order to reduce the length of the step mark 4 generated when the strip 2 is wound, corrugated cardboard is put on the outer circumference of the inner circumference of the strip 2 and then the strip 2 is wound. There existed a big problem that the deviation of the length of the level | step difference mark 4 which arises accordingly is large.
또한, 골판지를 스트립(2)의 단차부에 정확히 일치하도록 덧대어도 스트립(2)의 두께가 1.5mm 이상인 경우에는 단차 마크(4)의 길이가 20m 이상 나타나는 등 품질 악화의 문제점이 여전히 존재하였다.In addition, even if the corrugated paper is padded to exactly match the stepped portion of the strip 2, there is still a problem of deterioration such that the length of the stepped mark 4 is 20 m or more when the thickness of the strip 2 is 1.5 mm or more.
본 발명에 따른 스트립 권취시 단차 마크 길이 저감 방법 및 이를 이용한 스트립은 상기한 바와 같은 종래 문제점을 해결하기 위해 안출된 것으로서, 다음과 같은 해결과제를 가진다.Method for reducing the step mark length during strip winding according to the present invention and a strip using the same are devised to solve the conventional problems as described above, has the following problems.

본 발명에 따른 스트립(2) 권취시 단차 마크(4) 길이 저감 방법은, (a) 스트립(2)의 내권부의 외주연을 종이로 덧대는 단계; (b) 릴(1)에 스트립(2)을 한 바퀴 감은 후 내권부의 단차부(3)와 접촉할 부분의 외주연에 에어캡(20)을 덧는 단계; (c) 스트립(2)을 릴(1)에 감는 단계를 포함한다. The method for reducing the length of the step mark (4) when winding the strip (2) according to the present invention comprises the steps of: (a) padding the outer periphery of the inner winding portion of the strip (2) with paper; (b) winding the strip 2 around the reel 1 and attaching the air cap 20 to the outer circumference of the portion to be in contact with the step 3 of the inner winding portion; (c) winding the strip 2 onto the reel 1.
스트립(2)이 릴(1)에 최초로 감기는 내권부의 외주연에 종이로 덧댄다. 그리고 릴(1)에 스트립(2)을 한 바퀴 감은 후 내권부의 단차부(3)와 접촉할 부분의 스트립(2) 외주연에 에어캡(20)을 덧댄다. 그리고, 종이와 에어캡(20)을 덧댄 스트립(2)을 릴(1)에 감는다.The strip 2 is padded with paper on the outer periphery of the inner circumference where it is first wound on the reel 1. Then, after winding the strip 2 on the reel 1, the air cap 20 is padded on the outer circumference of the strip 2 of the part to be contacted with the step 3 of the inner winding portion. Then, the strip 2 padded with paper and the air cap 20 is wound on the reel 1.
여기서 '에어캡'이란, 2장의 폴리에틸렌(polyethylene) 필름을 포개어 그 사이에 공기의 거품을 가둔 것으로서, 기포가 들어간 필름의 일종을 말한다. 산업계에서 흔히 '뽁뽁이'로도 불리는 것이며, 통상 산업계에서 쓰이는 에어캡이면 족하다.Here, the air cap refers to a kind of film in which two bubbles of polyethylene are stacked and a bubble of air is trapped therebetween. It is also commonly referred to as the 'cheong' in the industry, and the air cap commonly used in the industry is sufficient.
본 발명에 따른 스트립(2) 권취시 단차 마크(4) 길이 저감 방법에 있어서, '종이' 는 마분지(30) 또는 골판지인 것을 특징으로 할 수 있다. 본 발명을 실시함에 있어서는 통상의 종이보다는 비교적 두께가 두꺼운 마분지(30) 또는 골판지(10)를 사용하여, 권취시킴으로써 단차 마크(4) 길이를 저감하도록 하였다.In the method for reducing the length of the step mark 4 when winding the strip 2 according to the present invention, the 'paper' may be characterized as cardboard 30 or cardboard. In carrying out the present invention, the length of the step mark 4 is reduced by winding the cardboard 30 or the corrugated cardboard 10, which is relatively thicker than ordinary paper.

In the method of reducing the length of the step mark 4 when the strip 2 is wound according to the present invention, when the diameter of the reel 1 is 20 ″, as shown in FIG. 5 (a), the inner winding portion of the strip 2 is shown. Step of padding the outer circumference of the paper with a piece of paper up to 1500mm from 400mm away from the step 3 of the strip 2, winding the strip around the reel (1) and then step (3) In the step of padding the air cap 20 on the outer circumference of the part to be contacted with), the air cap 20 is padded up to 200 mm from the point where the paper is padded (see FIG. 5 (a)).
하기의 실시예는 릴(1)의 직경이 20″인 경우, 골판지(10) 또는 마분지(30)를 사용하여 스트립(2)에 덧대고, 릴(1)에 스트립(2)을 한 바퀴 감은 후 내권부의 단차부(3)와 접촉할 부분의 스트립(2) 외주연에 에어캡(20)을 덧대는 등의 비교 실험을 하였다. 비교 실험에 대한 결과는 다음의 실시예 1에서의 표와 같다.In the following example, when the diameter of the reel 1 is 20 ″, the strip 10 is padded using the cardboard 10 or the cardboard 30, and the strip 2 is wound around the reel 1. After that, a comparative experiment was performed such as padding the air cap 20 on the outer periphery of the strip 2 of the portion to be contacted with the step 3 of the inner winding portion. The results for the comparative experiments are shown in the table in Example 1 below.
