Description

관의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1도는 필거 리덕션(Pilger reduction)과 같은 변형공정에 의해 지르코늄 합금관에 정상적으로 생기는 베이셜폴(basal pole)방향의 도해,
제 2도는 관의 제조방법의 중간단계에서 지름의 팽창과 재결정 어니일링이 있는 것과 없는 지르코늄합금관의 일련의 공정의 각단계에서 조직이 어떻게 변하는가를 설명하는 도표.

Claims (8)

  1. 결정구조에서 베이셜폴의 방사상조직을 향상시키기 위하여 조밀육방결정구조를 갖는 금속재료로 구성된 관의 제조방법에 있어서, 단면적을 적어도 한번 감소하고 다음에 재결정 어니일링이 행하여지는 중간단계와, 관의 단면적을 최종적으로 감소시키고 다음에 최종어니일링이 행하여지는 최종단계로 이루어지고, 상기 중간단계동안 관의 지름의 크기에서 적어도 한번 팽창을 갖고, 상기 치수의 팽창다음과 상기 최종 단계 전에 재결정어니일링을 갖는 것을 특징으로 하는 관의 제조방법.
  2. 제 1항에 있어서, 지름의 치수가 5 내지 12% 증가되는 것을 특징으로 하는 관의 제조방법.
  3. 제 1항 또는 제2항에 있어서, 지름의 팽창다음에 재결정 어니일링이 약 677℃에서 적어도 4시간동안 행하여지는 것을 특징으로 하는 관의 제조방법.
  4. 제 1항, 제 2항 또는 제3항에 있어서, 관의 지름이 팽창되는 동안 관의 벽두께가 감소되는 것을 특징으로 하는 관의 제조방법.
  5. 제 1항 내지 제 4항중 어느 한 항에 있어서, 중간단계와 최종단계에서 관의 단면적 감소가 상기 관의 축방향 연산뿐만 아니라 벽두께과 지금의 감소를 일으키는 것을 특징으로 하는 관의 제조방법.
  6. 제 1항 내지 제 5항중 어느 항에 있어서, 상기 중간단계동안 각각의 재결정 어니일링이 약 677℃에서 행하여지는 것을 특징으로 하는 관의 제조방법.
  7. 제 1항 내지 제 6항중 어느 항에 있어서, 중간단계는 각각의 감소 다음에 재결정 어니일리이 따르는, 복식의 관의 감소를 포함하고, 관의 지름에서 적어도 한번의 팽창이 상기 복식의 관감소의 어느 하나와 그것에 관련한 재결정어니일링 다음에 행하여지는 반면 재결정 어니일링은 상기 중간단계와 최종단계중 어느단계에서 다음관 감소전인 상기 지름의 팽창다음에 행하여지는 것을 특징으로 하는 관의 제조방법.
  8. 제 1항 내지 제 7항중 어느 항에 있어서, 관는 지르코늄합금재료로 구성되어 있는 것을 특징으로 하는 관의 제조방법.
