It is used for annealing protection gas, sintering protection gas, nitriding treatment, furnace cleaning and purging gas, etc. 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 require 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: annealing and 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 provides protection gas and safety gas for industrial furnace during bright annealing, bright quenching and other heat treatment processes to prevent oxidation of products.

Nitrogen gas source for heat treatment such as bright quenching, bright annealing, nitriding, nitrocarburizing, soft carbonization, and protection gas during welding and powder metallurgy sintering

In the application of metal heat treatment, nitrogen is used for annealing protection atmosphere of alloy steel and high carbon steel, metal powder sintering protection atmosphere, nitriding treatment, furnace cleaning and purging gas, etc. The high quality nitrogen provided by Rita Heng Gas for this purpose has a purity of more than 99.9995% and a dew point of less than - 65 ℃.

The nitrogen-based atmosphere heat treatment based on nitrogen odor is a new technology and process for energy saving, safety, non-polluting the environment and making 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 atmosphere, and the quality of the metal parts treated can be comparable to the traditional endothermic atmosphere treatment.

Aluminum products, aluminum profile processing, aluminum thin rolling and other gas protection in aluminum processing industry.

Powder metallurgy powder sintering, nitrogen protection in magnetic material sintering.

Synthetic fiber nitrogen-filled pressing material, drawing and anti-oxidation.

Nitrogen-filled lead-free soldering is used for reflow soldering and wave soldering.

Protective gas for continuous casting, rolling and steel annealing in metallurgical industry; Combined nitrogen blowing at the top and bottom of the converter for steelmaking, sealing of the converter for steelmaking, sealing of the top of the blast furnace, and gas injection of pulverized coal for blast furnace ironmaking.

The application of nitrogen for metal deep processing in steel and iron is mainly used as protective gas, such as steel rolling, galvanizing, chrome plating, continuous casting and so on. The purity of nitrogen is required to be more than 99.99%. The nitrogen purity can reach 99.9995% for the gas solution provided by Rita Heng Gas.

Nitrogen is mainly used for inert gas cross-linking in the generation of medium and high voltage cables. Polyethylene insulation material added with peroxide cross-linking agent is used to complete the extrusion of conductor shielding layer - insulation layer - insulation shielding layer through three layers of co-extrusion, and then the cross-linking process is completed continuously and evenly through sealed cross-linked pipes filled with high temperature and high pressure nitrogen. The heat transfer medium is nitrogen (inert gas). The cross-linked polyethylene has excellent electrical performance and the production range can reach 500KV.
