Why use air cutting carbon steel sheet or stainless steel sheet?
Air cutting is a must element in the working process of fiber laser cutting machine. It can blows the liquid steel, to ensure and fasten the cutting(dried air and oxygen)
* Nitrogen suitable in stainless steel, aluminum, copper cutting(nitrogen must be pure nitrogen)
*Oxygen suitable in carbon steel cutting(Oxygen must be pure oxygen)
* Air suitable in carbon steel and stainless steel sheet cutting. (Air must be processed to be dry and client, so there muse be a air compressor and filtrate oil and moisture and dust)
As Nitrogen is expensive in some countries. While some situations the clients won’t high standard cutting edge. Air as auxiliary gas will cause cutting edge oxidized. As the cutting material as well as the thickness differs, the consumption may be different.
Cutting gas consumption:
- Take the wild steel with thickness 1mm as example
Oxygen at 0.7 bottle per hour, cost 14RMB per hour(oxygen bottle with standard of 15.5 Mpa, purity of 99.5%, 20RMB per bottle);
- Talk the stainless steel or alloy with thickness 1mm as example
If most of the work is ss or alloy, it is suggested to apply liquid nitrogen(125Kgs per bottle, and 320RMB per bottle, and change very bottle of 12 hours)
