In actual processing applications, the processing q235b carbon coil thickness of flame cutting ranges from 6 to 200 mm, and the q235b carbon 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 q235b carbon coil with a certain thickness above 10mm.

Q345E steel is low-alloy high-strength steel with good low-temperature impact properties. The grade of Q345E steel is composed of three parts: Chinese phonetic alphabet representing yield strength, yield strength value and quality grade symbol. Where: Q is the yield strength; 345 is the yield strength value in MPa; E is the grade (passing the - 40 degree impact test). q235b carbon coil, Q345E steel is mainly used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, power stations, workshops, low-temperature pressure vessels, etc.

The height from the cutting nozzle to the q235b carbon coil cutting surface is one of the main factors to determine the cutting quality and cutting speed in the flame cutting process. Different thickness of steel plate, using different parameters of cutting nozzle, should adjust the corresponding height. In order to ensure a high quality cut, the height from the cutting tip to the surface of the workpiece to be cut must be basically the same throughout the cutting process. Master the above three factors affecting the flame cutting quality of q235b carbon coil steel plate, for the production efficiency will be significantly improved.
