Precious metals and heat treatment industry applications

Heat treatment processing mainly includes bright quenching, bright annealing, bright annealing, continuous casting, continuous rolling, steel strip; aluminum strip, aluminum thin rolling and other protective heating to prevent oxidation and decarbonization of products. The application of nitrogen generator in heat treatment and processing has the following aspects:

1.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.

2.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.

3.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. 4.Protection gas and safe gas: blowing and exhaust in the furnace, and sealing the air curtain of the furnace door; when the gas is stopped and power is off, the nitrogen produced by the nitrogen generator can be sent into the furnace to prevent the gas explosion.
