Abstract
Description
도 1은 예를 들어 7XXX-시리즈 알루미늄 합금의 플레이트 제품 제조를 위한, 종래 기술에 따른 방법의 개략적인 흐름도를 제공한다. 제1 단계(20)에서 7XXX-시리즈 알루미늄 합금의 압연 공급원료는 반연속 주조 또는 연속 주조 기술에 의해 주조된다. 압연 잉곳은 단계(30)에서, 바람직하게는 400℃내지 480℃범위의 온도에서 균질화 및/또는 예열된다. 압연 잉곳은 단계(40)에서 더 얇은 게이지로 열간 압연되고, 나가는 최종 열간 압연 스탠드는 (더 얇은 게이지 제품의 경우) 권취되고 주위 온도로 천천히 냉각되고 또는 더 두꺼운 게이지 제품의 경우 주위 온도로 천천히 냉각되고 길이에 맞게 절단되고, 선택적으로 단계(50)에서 최종 게이지로 추가로 냉간 압연되고 후속적으로 길이에 맞게 절단된다. 최종 게이지에서 압연 제품은 단계(60)에서 전형적으로 400℃내지 480℃범위의 온도에서 용체화 열처리되고 단계(70)에서 소입된다. 신장 작업(80)에서 제품은 응력 완화되고 제품 평탄도가 증가하며, 예를 들어 T7651 조건으로의 인공 시효에 의한 시효 작업(90)이 이어진다.
