Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 용접된 대구 경강관의 제조법을 도시하는 개략도.
제2도는 이음매 없는 대구 경강관의 제조법을 도시하는 개략도.
Claims (1)
- 다음의 세가지 제조단계를 사용하는 것을 특징으로 하는 이음매없는 대구 경강관의 제조법으로서, 1) 공지된 연속주조방법으로 중공강괴의 제조단계, 2) 장력이 가해진 맨드릴을 갖는 공지된 경사압연기에 상기 중공강괴를 통과시켜 일정한 미터중량으로 압연하는 단계, 3) 공지된 확장압연기를 이용하여 축방향신장을 하지않고 미터 중량을 거의 동일하게 유지하면서 요망하는 최종치수로 확장시키는 단계들로 이루어지는 강관제조법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
