Description

대기용해에 의한 알루미늄-리튬합금의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 의한 용탕의 탈가스에 사용되는 장치의 일예를 보인 단면도.
제2도는 본 발명의 실시에 사용되는 주조장치의 일예를 보인 개략단면도.

Claims (3)

  1. 금속리튬을 제외한 알루미늄 및 기타 합금원소를 대기중에서 용해하고 그 용탕의 표면을 용제로 피복한 상태에서 일반적으로 사용되는 탈가스제를 이용하여 1차 탈가스처리를 한 후, 알루미늄으로 피복된 금속리튬을 첨가하여 알루미늄-리튬합금의 용탕을 제조하고, 이어서 용탕내에 가스버블러를 침지시켜 불활성가스를 취입시켜 용탕의 2차 탈가스처리를 수행한 다음, 용탕을 불활성분위기로 유지되어 있는 주형에 주입하는 과정에서 밀폐된 용탕의 밀폐된 주입유로상에 불활성가스를 유입시켜 3차 탈가스처리하여 건전한 알루미늄-리튬합금의 잉곳트를 제조함을 특징으로 하는 대기용해에 의한 알루미늄-리튬합금의 제조방법.
  2. 제1항에 있어서, 용제는 LiCl 또는 LiF인 것을 특징으로 하는 대기용해에 의한 알루미늄-리튬합금의 제조방법.
  3. 제1항에 있어서, 2차 탈가스처리는 가스버블러를 통하여 알곤가스를 1-5ℓ/min의 유입속도로 4-10간 유입시킴에 의해 수행됨을 특징으로 하는 대기용해에 의한 알루미늄-리튬합금의 제조방법.
