Industrial specialty gases and applications for foundries

Experience you can count on

Linde has the depth of experience needed to bring advanced industrial solutions to the foundry industry. From direct oxygen injection into the iron cupola to Laminar Barrier Inerting for induction furnaces, we can help improve your productivity, manufacturing capacity and metal quality.

Related Gases

Oxygen Oxygen rollover Oxygen

Oxygen is used to increase productivity and reduce fuel consumption in rotary furnaces, ladle preheaters and cupola furnaces.

Nitrogen Nitrogen rollover Nitrogen

At the core of our heat-treating application, nitrogen is a non-flammable industrial gas used to rid oxidizing gases from your processes.

Hydrogen Hydrogen rollover Hydrogen

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


Cost effective and highly productive, our wide range of heat-treating industrial solutions can help you make precisely reproducible metals.

Our Laminar Barrier Inerting process excludes unwanted gases from the headspace of induction furnaces to increase yield and lower dissolved oxygen, nitrogen and hydrogen in your metal.

Our Dilute Oxygen Combustion application converts air-fuel burners into oxy-fuel for ladle preheating — reducing fuel consumption, emissions and maintenance.

Our supersonic direct oxygen injection process blasts pure oxygen into the iron cupola resulting in more efficient use of energy resources.
