摘要： A multi-part oxy-fuel cutting tip has mixture outlet passages formed by swaging the tip skirt to form grooves. The grooves then cooperate with the tip core to form the outlet passages when the skirt is placed over the tip core. Oppositely directed circumferential inlet passages for the preheat oxygen and fuel promote rapid mixing while producing a non-rotating mixture flow. In addition, the sectional areas of the outlet passages decrease in the flow direction. These features promote the rapid creation of a laminar mixture flow.
摘要翻译： 多部分氧 - 燃料切割尖端具有混合物出口通道，其通过将尖端裙边锻造以形成凹槽而形成。 然后，当裙部放置在尖端芯上时，凹槽然后与尖端芯配合以形成出口通道。 用于预热氧气和燃料的相对定向的圆周入口通道促进快速混合，同时产生不旋转的混合物流。 此外，出口通道的截面积在流动方向上减小。 这些特征促进了层流混合物流的快速生成。
