Specialized Nitrogen Generator For Precious Metals And Heat Treatment Industry Applications

Nitrogen is mainly used in the heat treatment process for bright quenching, bright annealing, bright tempering, continuous casting, rolling, steel strip, aluminum strip, aluminum thin rolling and other processes to protect heating and prevent oxidation and decarburization of products. The application of nitrogen generators in heat treatment processing includes the following aspects:

Vacuum heat treatment: when the nitrogen is used as a cooling medium for nitrogen-charging pressurized oil quenching, adjust the nitrogen pressure of the nitrogen generator, improve the hardening of the steel parts, and protect the electric heating components of the vacuum furnace. Electronic industry semiconductor and integrated circuit manufacturing process of atmosphere protection, cleaning, chemical recycling, etc.

1. Controlled atmosphere: nitrogen, as a dilution gas, can reduce the consumption of raw material gas and reduce the formation of carbon black. Nitrogen source for large-scale integrated circuit, color TV imaging tube, TV and cassette components and semiconductor components.

2. Carburization and nitrogen infiltration: the nitrogen produced by the nitrogen machine can be used for anti-oxidation cooling after carburization, reduce the internal oxidation degree of steel parts, improve the decomposition rate of furnace gas and the waste labor strength and breaking resistance of parts. In the production process of electronic components and semiconductor components, nitrogen gas with a purity of 99.999% is used as a protective gas. At present, high purity nitrogen has been used as carrier gas and protective gas in the production process of color TV picture tube, large-scale integrated circuit, liquid crystal and semiconductor silicon wafer.

3. Protection gas and safe gas: Use nitrogen for blowing and exhausting inside the furnace, as well as sealing the gas curtain of the furnace door. When the gas and power are cut off, the nitrogen produced by the nitrogen generator can be sent into the furnace to prevent furnace gas explosion.

When the air in the pressurized through the purification and drying, Base on Aerodynamics, nitrogen and oxygen in the air in the zeolite molecular sieve (ZMS) on the Pressure swing adsorption  will performance of different diffusion rate through the adsorption of nitrogen. Oxygen in carbon molecular sieve on the surface of the diffusion rate is higher than nitrogen. When the adsorption was not in balance, oxygen was absorbed by carbon molecular sieve in large quantity, and nitrogen was concentrated and enriched in the gas phase to achieve separation of oxygen and nitrogen.
