Nitrogen application in cutting

Cutting using nitrogen solved many problems of processing in the actual production, and processing will extend to the aluminum, brass, and other areas of the oxygen cutting hard to processing. Below to introduce its application in the field of all kinds of materials,.





1. Carbon steel

use oxygen cutting carbon steel. Surface temperature are very high because of the auxiliary melting, oxygen as auxiliary combustion of carbon. When cutting sharp Angle, the hole diameter smaller than the material thickness, the narrow region focused too much heat, cutting quality cannot be guaranteed. Nitrogen auxiliary combustion, and has a cooling effect, suitable for solving this kind of processing problems, can improve the quality of the product.

2。 Stainless steel

from cost to consider, cutting edge oxidation by oxygen cutting does not affect the use of stainless steel parts. But the content of alloy elements such as Ni stainless steel is larger, melt viscosity, liquidity is poor, low air pressure when oxygen cutting is easy to cause quality defects such as viscous slag. When the welding of stainless steel oxide layer seriously affect the welding quality, especially the argon arc welding. Providing high quality without oxidation nitrogen gas cutting section, to meet the high demand of the stainless steel welding to cutting section.

3。 Aluminum, brass,

aluminium, brass with high reflectivity and low absorption rate, high power to melt material. And equipped with reflection absorption equipment, make rough linear wave is not reflected back to a lens, to the safety of the protector. For nitrogen gas cutting.

aluminum melting point is lower, the following 3 mm thick available oxygen cutting, but the quality is poor, cross section and the burr is hard. Using nitrogen gas cutting section is smooth, 4 mm thick can gain the following without burr effect. Big viscosity and thermal conductivity, aluminum melt have been cooled before may blow away, so it's easy to have a burr. By adjusting the focus, higher air pressure, reduce speed to reduce the surface roughness value, to ensure that the burr to clean.

4。 Etching

etching is a special cutting, only 5% of basic power energy. It is only on the material surface, mainly used for etching tag. Oxygen etching temperature height, sometimes surface welding slag. Concentrated etching damage due to heat concentrated parts surface. Nitrogen etching the light and do not damage the surface, can be used to etch the caption of high demand.

oxygen cutting thickness, low cost, is mainly used in carbon steel. Nitrogen cooling, protective effect to improve the cutting quality, and in the cutting of stainless steel, aluminium, brass made good effect, solved many problems of processing.

in addition, not the characteristics of the auxiliary combustion can also be used to processing and special material such as wood, organic glass, has a broad application prospect.
