Steel Mills

Industrial specialty gases and technology for STEEL mills

Produce more with less

Linde has a wide array of industrial applications throughout the processing chain of steel production in both integrated steel mills and mini-mills. We work with our customers to develop new applications for improved energy efficiency and environmental benefits. From COJET® gas injection technology in electric arc furnaces to ladle preheating, Linde’s industrial applications can help your steel mill produce more steel at a lower cost and with less energy while delivering improved environmental benefits.

Related Gases

Argon Argon rollover Argon

A key component in our Argon Oxygen Decarburization technology, argon is used to create over 75% of the world’s stainless steel.

Oxygen Oxygen rollover Oxygen

Introducing oxygen into your iron and steel making processes can help you reduce fuel use, produce higher temperatures and lower production costs.

Nitrogen Nitrogen rollover Nitrogen

Found at the core of our heat-treating industrial applications, nitrogen is non-flammable gas used to rid unwanted gases from your processes.

Hydrogen Hydrogen rollover Hydrogen

Hydrogen is used to prevent oxidation and is the key component in the heat treating process.


Our state-of-the-art oxygen injection system, COJET Gas Injection, is a leading industrial technology for burner, lancing and post-combustion in electric arc furnaces because it lowers cost and increases productivity.

With our Dilute Oxygen Combustion industrial technology you can easily convert burners to oxy-fuel systems to improve heat times and temperatures of your reheat furnaces and ladle preheating systems.

Whether you need hydrogen or nitrogen-based atmospheres, we provide cost-effective, high-productivity heat-treating industrial applications to help you achieve precise, reproducible results.

Adaptable to nearly every system and easy to install, our Laminar Barrier Inerting industrial application excludes unwanted gases from your processes to reduce oxidation and slag formation.

Our Stove Oxygen Enrichment application can produce higher temperatures in blast furnaces with oxygen, reducing or potentially even eliminating the need for natural and coke oven gases.

Our Hot Oxygen Technology is specially designed for enhanced Pulverized Coal Injection (PCI) into your blast furnace. By applying this technology you may increase your PCI rates.


We offer more than industrial gases and applications to mini mills. We work with you to optimize your process. From consultation to implementation and use, we offer a range of services that help you manage your gas supply and make a better product.
