In actual processing applications, the processing Q355NH, Q500NH, Q550NH steel coil thickness of flame cutting ranges from 6 to 200 mm, and the Q355NH, Q500NH, Q550NH steel coil cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting Q355NH, Q500NH, Q550NH steel coil with a certain thickness above 10mm.
