Description

압연방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 압연방법을 수행하는 데에 사용하기 적절한 제어시스템과 텐덤 압연기의 계통도.
제2도는 제1도에 도시한 텐덤압연기의 다수 상류로울 스탠드중의 하나에 있는 작업로울과 지지로울의 배열예의 정면도.
제2A도와 2B도는 제2도에 유사한 도면으로 제1도에 도시한 압연기의 하류로울스탠드에 있는 작업로울과 지지로울의 정면도.
제3도는 경우 A(작업로울들이 크라운 제어에서 패턴을 이동시키지 않음)와 경우 B(로울 프로우필이 제어됨)의 관계에서 작업로울 국부마모와 작업로울마모프로우필을 도시한 다이어그램.

Claims (8)
