Auxiliary gas cutting machine why need?
by：ZORON Machinery
2021-01-29
Cutting machine auxiliary gases used in the processing of different materials are distinguished.
Cutting thickness different its auxiliary gas pressure and requirements are different.
From cost, oxygen cutting carbon steel with relatively cheap, don't cut carbon steel nitrogen amount is large, the more thick stainless steel dosage and nitrogen purity requirement, the cost is relatively high.
of the gas cutting machine mainly used in:
1, gas ( A gas generator used for)
2, compressed air, Generally used to protect optical path, some manufacturer also used for protection of gas)
3, auxiliary gas ( Is the building Lord said out of the cutting machine cutting nozzle spray gas)
cut carbon steel with oxygen, it is in commonly 99 purity requirements. 5% or higher. The main role is combustion and blow off cutting slag. Pressure and flow rate of each different cutting machine manufacturers, with the cutting nozzle size, cutting material thickness are inseparable. General requirements at zero pressure. 3 - 0. General 0 8 mpa, cut the mouth. 02-0. 05Mpa。 Traffic is bad to say, such as carbon steel cutting 22 mm, the flow of some manufacturers to achieve 10 m3 / h ( Including the protection of the double nozzle with oxygen) Have high request for the purity of nitrogen ( More than 8 mm stainless steel, in particular, require general to reach 99. The purity of 999%) The flow according to the cutting nozzle model have change, but are very big, such as cutting 12 mm stainless steel to some manufacturer to 150 m3 / h and cut 3 mm, as long as 50 m3 / h the following traffic.
