The Metallurgical special nitrogen system is composed is a compressed air device, a compressed air purification device, a pressure swing adsorption nitrogen generator, a nitrogen purification device, a nitrogen storage device and the like. Special nitrogen generators for metallurgical industry are suitable for heat treatment, bright annealing, protective heating, powder metallurgy, copper and aluminum processing, magnetic material sintering, precious metal processing, bearing production and other fields. It has high purity, continuous production, and some processes require nitrogen to contain a certain amount of hydrogen to increase the brightness.
Steelmaking converter sealing, blast furnace top sealing, blast furnace ironmaking pulverized coal injection, continuous casting, continuous rolling, steel annealing, stress relief, aging, quenching heating, carburizing, nitrocarburizing, soft nitriding, vacuum quenching, etc. A nitrogen source for heat treatment in a nitrogen atmosphere, a shielding gas for welding and powder metallurgy sintering, and a cleaning and dilution gas.
