Description

에징 압연 롤{edging roll}Edging roll

본 발명은 압연 롤에 관한 것으로서 보다 상세하게는 에징 압연 롤에 관한 것이다.The present invention relates to a rolling roll, and more particularly, to an edge rolling roll.

일반적으로 철강의 제조공정 중에서 압연 공정은 다양한 형태의 압연기를 이용하여 반제품을 원하는 규격의 제품으로 생산한 것인 바, 이때 압연기는 다수의 압연 롤을 갖추고서 반제품을 가압하여 원하는 형상의 제품으로 성형하게 된다.In general, the rolling process in the manufacturing process of steel is to produce a semi-finished product to a product of a desired standard using a variety of rolling mills, in which the rolling mill is equipped with a plurality of rolling rolls to press the semi-finished product to form a product of the desired shape Done.

상기 압연기는 그 외주면에 압연재의 형상에 따라 다양한 형면이 형성된 상,하 한 쌍의 압연 롤이 회전하면서 압연하게 되어 있다. 상기 압연 롤은 압연공정에 따라 조압연 롤, 중간압연 롤, 사상압연 롤로 나뉘어지는데, 상기 사상압연 롤의 하나로서 압연제품의 가장자리 팁(tip)부위만 압연하는 에징 압연 롤이 개시되어 있다.The rolling mill is configured to roll while rotating a pair of upper and lower rolling rolls formed with various mold surfaces according to the shape of the rolling material on the outer circumferential surface thereof. The rolling rolls are divided into rough rolling rolls, intermediate rolling rolls, and finishing rolling rolls according to a rolling process. As one of the finishing rolling rolls, an edging rolling roll for rolling only an edge tip portion of a rolled product is disclosed.

에징 압연 롤은 압연제품의 가장자리만 압연하는 롤로서 부하가 많이 걸리지 않는 롤이지만 중량이 크고, 형면의 다른 부위에 비해 팁부위가 쉽게 마모되므로 전체 에징 압연 롤을 자주 교체하여야 하므로 새로운 에징 압연 롤의 개발이 요구되고 있다. The edging roll roll is a roll that rolls only the edge of the rolled product, and it does not take much load, but the weight is large and the tip portion wears easily compared to other parts of the mold surface. Development is required.

본 발명은, 이러한 요구에 부응하여 이루어진 것으로서, 본 발명의 목적은 형면의 마모시 슬리이브만 분리하여 교체함으로써 아버를 재사용하여 롤교체비용을 줄이고 다양한 형상의 압연제품에 따라 슬리이브의 폭을 가변함으로써 롤제조비용을 줄이는 에징 압연 롤을 제공하는 데 있다.The present invention has been made in response to such demands, and an object of the present invention is to reuse the arbor by separating and replacing only the sleeve when the mold is worn down, thereby reducing roll replacement cost and varying the width of the sleeve according to various rolled products. The present invention provides an edge rolling roll that reduces the roll manufacturing cost.

본 발명에 의한 에징 압연 롤은, 압연제품의 형상에 따라 외주면에 형면이 형성된 슬리이브와, 상기 슬리이브에 끼워져 압연기에 지지되어 회전하는 아버로 이루어지되, 상기 아버와 슬리이브는 열박음에 의해 결합되어 있다.The edging rolling roll according to the present invention comprises a sleeve having a mold surface formed on its outer circumferential surface according to the shape of a rolled product, and an arbor inserted into the sleeve and supported by a rolling mill to rotate the arbor and the sleeve by shrinking. Are combined.

본 발명에 의한 에징 압연 롤은, 압연제품의 형상에 따라 외주면에 형면이 형성된 슬리이브와, 상기 슬리이브에 끼워져 압연기에 지지되어 회전하는 아버로 이루어지되, 상기 슬리이브는 가변수단에 의해 전체폭이 가변되는 가변슬리이브가 결합된 구조로 되어 있다.The edging rolling roll according to the present invention comprises a sleeve having a mold surface formed on its outer circumferential surface according to the shape of a rolled product, and an arbor fitted to the sleeve and supported by a rolling mill to rotate the sleeve. This variable variable sleeve is combined.

상기 가변수단은 상기 가변슬리이브의 사이에 설치되는 유압실린더를 구비한다.The variable means has a hydraulic cylinder which is installed between the variable sleeve.

본 발명에 의한 에징 압연 롤에 의하면, 형면의 마모시 슬리이브만 분리하여 교체함으로써 아버를 재사용하여 롤교체비용을 줄이고 다양한 크기 및 형상의 압연제품에 따라 슬리이브의 폭을 가변함으로써 롤제조비용을 줄이는 효과가 있다.According to the edging rolling roll according to the present invention, the roll manufacturing cost is reduced by reusing the arbor by removing and replacing only the sleeve when the mold surface is worn, and reducing the roll replacement cost and varying the width of the sleeve according to the rolled products of various sizes and shapes. It has the effect of reducing.

이하, 본 발명의 실시예에 대해 첨부도면을 참조하여 상세히 설명한다. 이하의 실시예에서는 찬넬(channel)의 플랜지 가장자리(에지)를 마무리 압연가공하는 에징 압연 롤을 예로 들어 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following example, the edge rolling roll which finish-processes the flange edge (edge) of a channel is demonstrated as an example.

도1은 본 발명의 제1실시예에 의한 에징 압연 롤을 나타내는 구성도이다. 도시한 바와 같이, 본 발명의 제1실시예에 의한 에징 압연 롤(100)은 압연제품(C, 찬넬)의 형상에 따라 외주면에 형면(111a, 111a')이 형성된 한 쌍의 슬리이브(110, 110')와, 상기 각 슬리이브(110, 110')에 끼워져 압연기(도시안됨)에 지지되어 회전하는 아버(120, 120')로 이루어진다.1 is a block diagram showing an edging roll roll according to a first embodiment of the present invention. As shown, the edging rolling roll 100 according to the first embodiment of the present invention is a pair of sleeves 110, the mold surface (111a, 111a ') is formed on the outer peripheral surface according to the shape of the rolled product (C, channel) , 110 ') and arbors 120 and 120' which are inserted into the sleeves 110 and 110 'and supported by a rolling mill (not shown) to rotate.

상기 일측(상측) 슬리이브(110)에는 돌출부로 된 형면(111a)이 형성되고, 상기 타측(하측) 슬리이브(110')에는 홈부로 된 형면(111a')이 형성되어, 찬넬 제품을 압연하는 형면을 이루고 있다.The one side (upper side) sleeve 110 is formed with a mold surface 111a formed as a protrusion, and the other side (lower) sleeve 110 'is formed with a groove surface 111a' formed with a groove portion, rolling the channel product To form.
