A203 Grade B steel plate gas cutting parameters is adjusted according to A203 Grade B thickness . Cutting parameters included cutting nozzle model, oxygen pressure, cutting speed and preheating flames of energy, such as the selection of process parameters is mainly according to the type of gas cutting machine and cutting thickness, as for no cutting A203 Grade B steel, takes an exam the similar steel plate cutting, cutting parameters, check the gas flowing cut chew at the same time.
Removing A203 Grade B steel surface dirt should be done before gas cutting, grease, and set aside space below, to facilitate the blowing out of slag. Gas cutting, the cutting torch movement should maintain a constant speed. A203 Grade B cut distance on the surface of the flame core tip with 2 ~ 5 mm will be advisable, too close will melt incision edge, too far will insufficient heat, easy to interrupt the cuting process.
In A203 Grade B plate cutting process, preheat flame should be big,and burning air flow length should exceed 1/3 of the workpiece thickness. Cutting nozzle and A203 Grade B steel surface should be about 10 ° ~ 20 ° inclination, which will make A203 Grade B steel plate edge uniform heat.
