Metallurgy, metal processing industry
It is used for annealing protective gas, sintering protective gas, nitriding treatment, furnace cleaning and purging gas, etc. 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 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 annealing, carbonization of steel, iron, copper and aluminum products, high temperature furnace protection, low temperature assembly and plasma cutting of metal parts, etc.
Metal heat treatment In the process of bright annealing, bright quenching and other heat treatment processes, provide protective gas and safety gas for industrial furnaces to prevent oxidation of products.
Nitrogen source for bright quenching, bright annealing, nitriding, nitrocarburizing, soft carbonization and other heat treatments, shielding gas in welding and powder metallurgy sintering process, etc.
Nitrogen is used in metal heat treatment applications, used for alloy steel, high carbon steel annealing protective atmosphere, metal powder sintering protective atmosphere, nitriding treatment, furnace cleaning and purging gas, etc. Dürr Gas provides high-quality nitrogen for this purpose, purity more than 99.9995%, the dew point is lower than -65 ℃.
Heat treatment in a nitrogen-based atmosphere with the basic ingredients of nitrogen odor is a new technology and new process for energy saving, safety, no environmental pollution and full use of natural resources. It has been shown that almost all heat treatment processes, including quenching, annealing, carburizing, carbonitriding, soft nitriding, and recarburization, can be performed in a nitrogen-based gas atmosphere, and the quality of the processed metal parts is comparable to Comparable to traditional endothermic atmosphere treatments.
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 Nitrogen-filled press material, drawing anti-oxidation.
Nitrogen-filled lead-free solder is suitable for reflow and wave soldering.
Metallurgical industry: protective gas for continuous casting, continuous rolling, and steel annealing; composite nitrogen-blowing steelmaking at the top and bottom of converters, sealing of converter steelmaking, sealing of blast furnace tops, blast furnace ironmaking pulverized coal injection gas, etc.
The application of nitrogen in metal deep processing in steel is mainly used as protective gas, such as steel rolling, galvanizing, chrome plating, continuous casting, etc., nitrogen is used as protective gas, and the purity of nitrogen is required to be more than 99.99%. Gas solution, nitrogen purity can reach 99.9995%.
The generation of medium and high voltage cables requires nitrogen
Inert gas cross-linking adopts polyethylene insulating material added with peroxy compound cross-linking agent, through three-layer co-extrusion to complete conductor shielding layer - insulating layer - insulating shielding layer. The sealed cross-linking tube completes the cross-linking process. The heat transfer medium is nitrogen (inert gas), the cross-linked polyethylene has excellent electrical properties, and the production range can reach 500KV.
