Description

내경 확장 용접 장치 { A dilating and welding machine for inside diameter of cold rolling coil }A dilating and welding machine for inside diameter of cold rolling coil}

본 발명은 내경 확장 용접장치에 관한 것으로서, 더욱 상세하게는 냉연코일의 내경에 권취를 위해 형성된 절곡단부를 펼 수 있는 자동화 장치를 제공하고, 절곡단부를 폄과 동시에 용접을 할 수 있게 하는 내경 확장 용접장치에 관한 것이다.The present invention relates to an internal diameter expansion welding device, and more particularly, to provide an automated device that can extend a bent end formed for winding on the inner diameter of a cold rolled coil, and to expand the inner diameter to allow welding at the same time as the bent end is cut. It relates to a welding device.

일반적으로, 철강제조공정의 특징은 여러공정들이 연속적인 흐름으로 구성된 일관공정으로서, 제선, 제강, 열연, 냉연 등 크게 4개의 주요공정으로 구분되며, 이 제선공정은 산화철 상태인 철광석을 고로에서 환원시켜 용선을 생산한다.In general, the steel manufacturing process is characterized by an integrated process consisting of a continuous flow of several processes, which are divided into four major processes: steelmaking, steelmaking, hot rolling, and cold rolling. This steelmaking process reduces iron ore in the blast furnace. To produce molten iron.

그리고, 용선은 제강공정의 전로에서 냉선 및 특수원소 등과 함께 용강이 되며, 이 용강은 연주공정의 연속주조설비에서 주조되어 230㎜ 두께의 주편으로 만들어지며 후공정의 소재로 공급되거나 슬라브상태인 반제품으로 출하된다.The molten iron is molten steel together with cold elements and special elements in the converter of the steelmaking process. The molten steel is cast in a continuous casting facility of the casting process, and is made of cast steel having a thickness of 230 mm and is supplied as a material for the post-processing or slab state. Is shipped.

또한, 열연공정은 조압연기와 사상압연기를 이용하여 강괴의 폭과 두께를 압연하여 두께 1.2∼25.4㎜ 코일로 만든다.In addition, the hot rolling process uses a rough mill and a finishing mill to roll the width and thickness of the steel ingot into a coil having a thickness of 1.2 to 25.4 mm.

마지막으로, 냉연공정에서는 열연코일을 산세처리해서 표면산화철을 제거하 고, 상온에서 두께 0.15∼3.2㎜의 판두께로 냉간압연한 후, 소둔(Annealing)을 통하여 강도를 조절하거나 조질압연(Skin Pass Mill)을 거쳐서 냉연제품을 만든다. Finally, in the cold rolling process, the hot rolled coil is pickled to remove the surface iron oxide, cold rolled to a sheet thickness of 0.15 to 3.2 mm at room temperature, and then the strength is adjusted through annealing or skin pass. Mill) to make cold rolled products.

이와 같이 제조된 냉연코일은 권취기를 거쳐 제품으로 출하되는데, 일반적으로 냉연강판의 엔드는 권취기에서 냉연강판의 권취시, 냉연강판에 걸리는 장력에 의하여, 처음 감기는 강판코일의 두께 때문에 2번째 감기는 코일부터 계속해서 하나의 감김코일에 1개소씩 두께 눌림자국이 발생한다. 이러한 엔드마크를 감소시키기 위하여 종래에는 권취기에 사용되는 고무 슬리브에 홈을 가공하여 이 홈으로 첫 번째 코일강판의 절곡된 단부가 들어오도록 하는 방법이 사용되고 있다.The cold rolled coil manufactured as described above is shipped to the product through a winding machine. In general, the end of the cold rolled steel sheet is wound by the tension applied to the cold rolled steel sheet when the cold rolled steel sheet is wound in the winder, so that the first coil is wound twice. From the coil, the pressing marks are generated one by one on the winding coil. In order to reduce this end mark, a method of conventionally machining a groove in a rubber sleeve used in a winding machine so that the bent end of the first coil steel sheet enters the groove.

권취된 냉연코일은 권취될때 걸리기 위해 가장 내측단이 절곡되어 절곡단부가 형성되는데, 이러한 부분은 사용시에 잘라내어야 하므로, 최근에는 권취되어 외경이 밴딩된 냉연코일의 내경을 확장시켜 절곡단부를 펴는 작업을 하게 된다.The coiled cold rolled coil is bent at the innermost end to be caught when it is wound, and a bent end is formed. This part has to be cut off at the time of use. Will be
