1 . 모괴의 어닐링은 다음을 보장합니다.
A) 튜브 성형 및 냉간 인발 중에 유발된 응력 제거
B) 냉간 인발을 위한 충분한 연성 및 부드러움
C) 용접 영역을 오스테나이트 성질로 변환
D) 금속 입자를 원래 형태로 재결정화하여 개선 내식성
2 . 그런 다음 튜브를 적절한 윤활제로 코팅한 다음 드로우 벤치 위에서 냉간 인발합니다.
1) 야금학적 구조를 변경하고 모재의 특성을 복원하기 위해
2) 더 가까운 치수 공차를 갖는 튜브를 얻기 위해
3) 더 작은 크기와 더 작은 크기의 튜브를 생산하기 위해 벽 두께
4) 용접 부분의 결정 구조를 모재의 결정 구조로 재정렬합니다.
5) 내부 비드를 제거/최소화합니다.
