Industrial gases for metal production industry

OxygenOxygen rollover oxygen

As part of metal processing, oxygen is used to replace air or increase the oxygen content of air, thereby improving the combustion efficiency in the production of ferrous and non-ferrous metals.

ArgonArgon rollover Argon

As a key part of stainless steel refining, argon can be used as a stirring agent to prevent the oxidation of molten steel.

NitrogenNitrogen rollover Nitrogen

As a carrier and purification gas for steel production, nitrogen is used to prevent oxidation and is a key component in heat treatment.

HydrogenHydrogen rollover hydrogen

Hydrogen can be used to prevent oxidation and is a key component of heat treatment.

Industrial applications in the metal production industry

Argon Oxygen Decarburization

More than 75% of steel worldwide is made using our Argon Oxygen Decarburization (AOD) technology. This technology can reduce material costs, produce more pure metals, and increase production efficiency.

Helicopter endothermic oxygen atmosphere

For foundries, small plants, and stainless steel plants, Praxair's CoJet® gas injection and Supersonic direct injection processes can reduce costs and increase furnace productivity.

Aerated combustion

Praxair's Lean Oxygen Combustion System can help you turn your air-fueled furnace burner into an oxy-fuel burner, which can increase production efficiency while reducing fuel consumption, operating costs and emissions.

Heat treatment

From annealing brazing to sintering carburizing, Praxair's nitrogen-hydrogen-based heat treatment process has the characteristics of low cost and high efficiency, helping you meet the standard requirements.

Thermal oxygen technology

Praxair's thermal oxygen system burns materials quickly and easily preheats oxygen to the required high temperature.

Inerting

Praxair's Laminar Barrier Inerting technology can reduce alloy oxidation, slagging, and dissolved oxygen, nitrogen, and hydrogen in the metal. The metal products produced are more fluid, easier to cast, and have fewer defects.

Oxygen enrichment in hot furnace

Higher combustion temperatures can be generated without burning more fuel. Praxair furnace oxygen enrichment applications can help you reduce or even eliminate the need for fuels such as coke oven gas and natural gas.

Industrial services for the metal production industry

Praxair not only supplies industrial gases, technologies and applications to the metal production industry, but also works with you to optimize the entire process. From consulting to implementation and practical use, Praxair provides you with a complete set of industrial services to assist in managing gas supply and protecting machines to produce higher quality products.
