所有气割用的割嘴都有相同之处 :在割嘴的中心有 1个氧气孔道 ,氧气孔道周围分布着一些或圆形或槽状的预热气体孔道。制造割嘴的材料是各种不同的合金 ,在选择割嘴时需要掌握 3点要素。割炬类型在切割时首先需要知道使用的是何种割炬。割炬决定了割嘴的配置形式 ,也决定了氧气 All cutting blades for gas cutting have the same features: There is an oxygen channel in the center of the cutting tip, and some or round or trough preheated gas channels are distributed around the oxygen channels. The material used to make the torch is a variety of alloys that require three points to master when selecting the torch. Torch Types The first thing you need to know when cutting is the torch you are using. Cutting torch determines the configuration of the cutting tip, but also determines the oxygen
