Metallurgy

Large quantities of oxygen, nitrogen and argon are used in the steel and metal industry. Oxygen is used as a booster and reaction medium for combustion processes for steel and cast iron and can reduce dust emissions and pollutants in flue gases. Argon is used as an inert gas for cleaning, homogenising and degassing in steel production and nitrogen and argon as inert gases in the non-ferrous metal industry. Reactive gases produce special metallurgical effects.
