It is used for annealing protective gas, sintering protective gas, nitriding treatment, furnace cleaning and purging gas. It is widely used in metal heat treatment, powder metallurgy, magnetic materials, copper processing, wire mesh, galvanized wire, semiconductor, powder reduction and other fields. Some of these industries need nitrogen with purity greater than 99.5%, while others require high-quality nitrogen with purity greater than 99.9995% and dew point lower than - 65 ℃.
Metal production and processing manufacturing industry: annealing and carbonization of steel, iron, copper and aluminum products, high temperature furnace protection, low temperature assembly and plasma cutting of metal parts.
In the process of bright annealing and bright quenching, metal heat treatment provides protective gas and safety gas for industrial furnace to prevent oxidation of products.
Nitrogen source for heat treatment such as bright quenching, bright annealing, nitriding, nitrocarburizing and soft carbonization, and protective gas for welding and powder metallurgy sintering
In metal heat treatment applications, nitrogen is used for alloy steel, high carbon steel annealing protective atmosphere, metal powder sintering protective atmosphere, nitriding treatment, furnace cleaning and purging gas, etc. the high quality nitrogen provided by duel gas for this purpose has a purity of more than 99.9995% and a dew point lower than - 65 ℃.
Nitrogen based atmosphere heat treatment with nitrogen odor is a new technology and process for energy saving, safety, environmental protection and full utilization of natural resources. It has been shown that almost all heat treatment processes, including quenching, annealing, carburizing, carbonitriding, soft nitriding and recarburization, can be completed in nitrogen based atmosphere. The quality of the metal parts treated is comparable to that of the traditional endothermic atmosphere treatment.
Aluminum processing industry, aluminum products, aluminum profile processing, aluminum thin rolling and other gas protection.
Powder metallurgy powder sintering, nitrogen protection in the sintering of magnetic materials.
The synthetic fiber is filled with nitrogen and pressed material, drawing and anti-oxidation.
Nitrogen filled lead-free tin soldering is suitable for reflow soldering and wave soldering.
Metallurgical Industry: protective gas for continuous casting, continuous rolling and steel annealing; top and bottom compound nitrogen blowing steelmaking of converter, sealing of converter steelmaking, top sealing of blast furnace, gas for pulverized coal injection in blast furnace ironmaking, etc.
