Metals & Materials Processing

Industrial gas supply, technology & equipment for metal production

Strengthening your process

As the preeminent outsourced gas supplier to the metal production industry, we at Praxair are proud to supply hundreds of steel and non-ferrous mills worldwide with industrial gases that help skyscrapers soar, trains run, and ships sail. Praxair’s industrial gases are used extensively in metal production to lower cost, improve energy efficiency, deliver environmental benefits, and improve productivity.

But our relationship with our customers goes much deeper than just industrial supply. We offer a wide range of services that include the design, build, start-up and support of applications equipment. And we provide everything from cylinders to on-site systems to integrated mills, mini mills, steel mills, foundries and non-ferrous mills for combustion processes. When you get all of your solutions from one industrial gas supplier, you have the time and the freedom to focus to on your business.

Industrial applications for the metal production Industry

Argon Oxygen Decarburization (AOD)

Over 75% of the world’s steel is made with our Argon Oxygen Decarburization (AOD) process. Lower your material costs, produce cleaner metals and increase productivity with AOD.

Direct Oxygen Injection 

Used in foundries, mini-mills and stainless steel mills, our CoJet® gas injection and Supersonic direct injection processes lower costs and improve furnace productivity.

Oxygen Enhanced Combustion

Our Dilute Oxygen Enhanced Combustion system helps convert your furnace air-fuel burners into oxy-fuel burners. This may increase your productivity and help decrease fuel consumption.

Hot Oxygen Technology

Our hot oxygen system rapidly burns hard to combust materials and easily preheats oxygen to high temperatures at point of use, to give you the best possible results. 

Stove Oxygen Enrichment

Our Stove Oxygen Enrichment application can help you reduce or potentially eliminate the need for fuels like coke oven gas and natural gas while generating higher blast temperatures.

Inerting

Our Laminar Barrier Inerting technology reduces alloy oxidation, slag formation, and dissolved oxygen, nitrogen, and hydrogen in metals to produce better fluidity and easier casting.

Heat Treating

Our nitrogen and hydrogen-based heat-treating processes are low in cost, high in productivity, and may help your operators precisely meet specifications.

Additive Manufacturing

Powder is the foundation of getting the right results. The proper atmosphere is critical to the quality and final composition of powder metal production.

Aluminum Die Cooling

Nitrogen-based cooling can help with temperature control in aluminum extrusion. It is an important step in producing quality products and maximizing productivity potential.  

Aluminum Melting

Our aluminum melting techniques may help you achieve higher production output in your furnace operations while providing energy savings and lowering your NOx emissions. 

Aluminum Dross Cooling

Our dross cooling application can help you develop your aluminum recovery process and increase your aluminum recovery rate. 

Mining 

We supply gases for mine inerting, flotation, leaching, roasting, pressure oxidation, carbonate precipitation, and pH control and water treatment.

 

PRAXAIR burners & systems FOR THE METAL PRODUCTION INDUSTRY 

OPTIVIEW Screen and Flame

OPTIVIEW™ Image Analysis System

The OPTIVIEW Image Analysis System uses flame image technology to enhance combustion control and reduce emissions. This innovation enables real-time, automatic control of the energy into the melting process.

OPTIFIRE Fluidic Burner

OPTIFIRE™ Fluidic Burner 

The OPTIFIRE fluidic burner has features that may help increase energy efficiency and productivity. A remote-controlled operation allows the flame to be directed at cold scrap and accelerates the meltdown in the furnace. The flame can be programmed to move on horizontal and vertical planes. 

Praxair CoJet Flame

CoJet® Gas Injection System

The CoJet Gas Injection system uses a process and injector nozzle that delivers a laser-like coherent jet of oxygen at supersonic speeds. It also allows for automatic furnace operation, decreases metal production costs through lower power consumption, and more. 

OPTIFIRE JL Burner

OPTIFIRE™ JL Burner

The OPTIFIRE™ JL Burner is designed to provide savings and improved production by increasing the melting rate with more cycles per day. This burner is best to use for applications that only use oxy-fuel.

 
OPTIFIRE Hybrid Burner

OPTIFIRE™ Hybrid Burner

The OPTIFIRE™ Hybrid Burner allows flexible use of air and oxygen. It can be operated with oxy-fuel combustion when high melting rates are needed and with air during the holding and alloying phases.
