超音速火焰精密切割是近几年来发展起来的一项新工艺,它是在普通氧气切割的基础上应用空气动力学的超音速喷管(拉伐尔喷管)原理来提高切割氧流的出口速度和圆柱度,使高速氧流激烈氧化切口的燃烧反应区,并强烈冲击切口的氧化溶液,从而使切割割缝小,热影响区缩小,割缝处粘渣少,清渣容易,因此被割工件表面光洁度提高,切割速度也能提高,它比旧式切割工艺有明显的优越性。 Ultrasonic Flame Precision Cutting is a new process developed in recent years. It uses the principle of aerodynamic supersonic nozzle (Laval nozzle) on the basis of common oxygen cutting to improve the exit of cutting oxygen flow Speed ​​and cylindricity, so that the high-speed oxygen flow intense oxidation incision combustion reaction zone, and a strong impact on the incision of the oxidation solution, so that the cutting kerf small, heat-affected zone narrowing, kerf less residue, slag easy, so was Cutting surface finish to improve the cutting speed can be improved, it has obvious advantages than the old cutting process.
