Steel Air Separation Equipment

Steel air separation equipment is a large-scale industrial gas production system based on cryogenic air separation technology. It is specially designed for the steel smelting industry and is used to efficiently produce key process gases such as high-purity oxygen (O₂), nitrogen (N₂), argon (Ar). The equipment adopts a low-temperature distillation process, and through compression, purification, liquefaction and distillation, it realizes efficient separation of air, meeting the strict requirements for gas purity, flow rate and stability in the steel production process.

Core technology advantages

• Cryogeni distillation technology: ultra-low-low temperature liquefaction separation from -170°C to -190°C ensures oxygen purity ≥99.6% and nitrogen purity ≥99.999%, meeting the key process needs such as blast furnace oxygen-rich spraying and converter steelmaking.
• High-efficiency and energy-saving design: optimize the heat exchange network and energy recovery system, reduce unit gas energy consumption, and improve the comprehensive energy efficiency of steel enterprises.
• Intelligent control system: Integrated DCS/PLC automated management to monitor gas production, storage and transportation in real time to ensure gas supply stability.
• Modular structure: It can be flexibly configured according to the scale of the steel plant, supporting different production capacity needs of 1000~100,000 Nm³/h.

Steel air separation equipment key uses

• Oxygen (O₂): used in blast furnace oxygen-rich injection (improving combustion efficiency), converter steelmaking (BOF) (accelerating decarbonization reaction), and arc furnace (EAF) (melting and molten steel refining).
• Nitrogen (N₂): used for continuous casting protection gas, pipeline purge, safety inertification, etc.
• Argon (Ar): used in stainless steel smelting (AOD/VOD furnace), effectively controls carbon and oxygen reactions, and improves the quality of steel.
