Self-produced nitrogen is used for annealing protection gas, sintering protection gas, nitriding treatment, furnace washing and purging gas. Widely used in metal heat treatment, powder metallurgy, magnetic materials, copper processing, metal wire mesh, galvanized wire, semiconductor, powder reduction and other fields. Some of these industries require nitrogen with a purity greater than 99.5%, while others require high-quality nitrogen with a purity greater than 99.9995% and a dew point lower than -65 ° C.
Metal production and processing manufacturing steel, iron, copper, aluminum products annealing, carbonization, high temperature furnace protection, low temperature assembly of metal parts and plasma cutting. In the process of bright annealing, bright quenching and other heat treatment processes, it provides protection gas and safety gas for industrial furnaces to prevent the oxidation of products. Bright quenching, bright annealing, nitriding, nitrocarburizing, soft carbonization and other heat treatment nitrogen sources, welding and powder metallurgy sintering process protection gas.
Nitrogen in the application of metal heat treatment, used for alloy steel, high carbon steel annealing protection atmosphere, metal powder sintering protection atmosphere, nitriding treatment, furnace washing and purging gas, Hongsuo purification to provide high-quality nitrogen, purity greater than 99.9995%, dew point below -65℃.
The heat treatment of nitrogen-based atmosphere with the basic components of nitrogen odor is a new technology and technology for energy saving, safety, no pollution to the environment and full use of natural resources. It has been shown that almost all heat treatment processes, including quenching, annealing, carburizing, carbonitriding, soft nitriding and carburizing, can be completed using nitrogen-based gas atmospheres, and the quality of the metal parts treated can be comparable to that of traditional endothermic atmospheres.
Aluminum processing industry aluminum products, aluminum profile processing, aluminum thin rolling and other gas protection. Powder metallurgy Powder sintering, nitrogen protection in magnetic material sintering. Synthetic fiber filled with nitrogen press material, drawing anti-oxidation. Nitrogen filled lead-free tin welding is a combination of reflow welding and wave soldering.
Metallurgical industry: protection gas for continuous casting, continuous rolling and steel annealing; Converter top and bottom combined blowing nitrogen steelmaking, converter steelmaking seal, blast furnace top seal, blast furnace iron pulverized coal injection gas, etc.
Metal deep processing: The application of nitrogen in steel is mainly used as a protective gas, such as steel rolling, galvanized, chromium plating, continuous casting, etc., nitrogen is used as a protective gas, and the purity of nitrogen is required to be more than 99.99%. The gas solution provided by Hongsuo Purification for this purpose can reach 99.9995% purity of nitrogen.
Nitrogen is required for medium and high voltage cable generation
Inert gas crosslinking is made of polyethylene insulating material added with peroxy compound crosslinking agent. After the conductor shielding layer -- insulation layer -- insulation shielding layer is extruded through three layers of co-extrusion, the crosslinking process is completed continuously and uniformly through a sealed cross-linked pipe filled with high temperature and high pressure nitrogen. The heat transfer medium is nitrogen (inert gas), the crosslinked polyethylene has excellent electrical performance, and the production range can reach 500KV.
