후판평면 형상개선 압연방법Thick Plate Flat Shape Improvement Rolling Method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 종래의 압연방법에 의한 최종강판의 평면도. 제 2도는 (가)는 길이방향 압연후 강판의 평면도. (나)는 폭압연만 한 경우 강판의 평면도. 제 3도는 길이방향 압연에서의 크롭에 대한 설명도.1 is a plan view of a final steel sheet by a conventional rolling method. 2 is a plan view of the steel sheet after longitudinal rolling. (B) is a plan view of the steel plate in case of only rolling. 3 is an explanatory diagram of a crop in longitudinal rolling.

Claims (1)

성형 압연 후 평면상에서 90°회전시켜 폭내기 압연을 거치고, 다시 90°회전시켜 최종길이 압연을 행하는 압연방법에 있어서, 최종강판 형상이 凹형 사이드크롭(1A)과 凸형 엔드크롭(2A)으로 이루어지는 것이 예측될 경우는, 성형압연 마지막단계에서 롤(Roll)간격을 압연도중 변화시켜 압연재(3) 선후단부를 중앙부 보다 얇게되도록 압연하고, 폭내기 압연 마지막단계에서 압연재(3)중앙부를 선후단부보다 얇게 압연하며, 반대로 凸형 사이드크롭(1B)과 凹형 엔드크롭(2B)을 갖는 최종강판형상이 예측될 경우는 성형압연 마지막단계에서 압연재(3)중앙부를 선후단부에 비해 얇게, 그리고 폭내기 압연 마지막단계에서 압연재(3) 선후단부를 중앙부에 비해 얇게 압연하므로 최종강판의 사이드크롭(1) 및 엔드크롭(2)을 동시에 감소시키는 후판평면 형상개선 압연방법.In the rolling method in which a roll is rolled 90 ° on a plane after rolling to form a breadth roll, and then rolled again by 90 ° for final length rolling, the shape of the final steel sheet is formed by the chamfer side crops 1A and the chamfer end crops 2A. If it is expected to be made, the roll spacing is changed during rolling in the final stage of forming rolling to roll the front and rear ends of the rolled material 3 so as to be thinner than the center portion, and the central portion of the rolled material 3 in the final stage of the spreading rolling. Rolling thinner than the leading end, on the contrary, when the final steel plate shape having the 사이드 side crop (1B) and 凹 end crop (2B) is predicted, the center of the rolled material (3) is thinner than the leading end at the end of forming rolling. And thickening plate shape improvement rolling room which reduces side crops (1) and end crops (2) of the final steel sheet at the same time by rolling the front and rear ends of the rolled material (3) thinner than the center part method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
