鋼板切割方法

火焰切割鋼板

作者:小鋼|點擊:|發表時間:2018-12-31

火焰切割鋼板簡介

  火焰切割鋼板指利天然氣火焰(氧和天然氣)將被切割的鋼板預熱到能夠劇烈燃燒的燃點,再釋放出高壓氧氣流,使鋼板進一步劇烈氧化並將燃燒產生的熔渣吹掉形成切口切割鋼板的過程。

火焰切割鋼板流程/步驟

  1、在開始切割鋼板前,先檢查氧氣瓶、天然氣瓶、高壓氧氣流是否處於關閉狀態,在檢查割咀有沒有堵塞是否正常,
最後在檢查輸氣管是否正常。

  2、全部檢查確認沒有問題之後,先開天然氣點火,點火時打火機頭要往下垂,需要注意安全以免火焰燒到手。

  3、割咀點著之後,就可以放氧氣慢慢調節火焰,把火焰調節到淡藍色,火焰燃燒過程中注意調節氧氣的大小以免火焰熄滅。

  4、割咀上的火焰調節好之後,就可以把鋼板進行預熱。當鋼板預熱至紅色時,就可以開高壓氧氣流進行鋼板切割。在切割過程中,注意控製好火焰,避免熄滅。割咀離鋼板距離不能超過1cm,也不能貼著鋼板切割以免燒壞割咀。
