레이저 절단기에 대한 불순한 질소의 영향

레이저 절단기의 질소 적용은 주로 스테인리스강 절단 시 보조 가스로 사용됩니다! 레이저 절단기에 대한 불순한 질소의 영향.

질소는 스테인레스 스틸의 보조 가스로 두 가지 기능이 있습니다.

1. 질소는 불활성 기체로 레이저 절단 시 산화 반응을 방지합니다. 스테인리스 제품 절단면의 금속광택(광택)을 유지합니다.

2. 레이저로 녹인 부분을 질소 압력으로 불어 절단 솔기를 형성하십시오!

일반적으로, 레이저 절단 질소에 대한 몇 가지 요구 사항이 있습니다.

청정

일반적으로 순도 요구 사항은 99.99%보다 높을수록 더 좋습니다! 그 이유는 스테인레스 스틸의 원래 금속 광택을 유지하기 위해 절단 스테인레스 스틸 절단 중 표면! 순도가 너무 낮으면 절단면이 생성됩니다. 산화 반응은 절단면의 황변 또는 흑화를 초래합니다. 질소 불순물의 영향

압력

압력은 절단된 스테인리스강의 두께에 따라 달라집니다. 일반적으로 10mm 미만의 1Mpa이면 충분합니다. 20mm 스테인리스강을 절단하려면 질소 압력이 일반적으로 2Mpa 이상입니다.

흐름

유량은 절단 노즐의 직경과 압력에 의해 결정됩니다. 물론 가장 큰 이유는 절단된 스테인리스 스틸의 두께 때문입니다. 후판 스테인리스라면 흐름이 매우 큽니다!
