Frequently Asked Questions about Steel Industry Industry
Why is oxygen used in the steel industry?
Oxygen increases combustion temperature in blast furnaces and electric arc furnaces. It also helps remove excess carbon from molten steel and improves refining efficiency. This gas is one of the fundamental elements of steelmaking processes.
What is the role of nitrogen in steel plants?
Nitrogen acts as an inert gas used for equipment cooling, pipeline purging, protecting molten steel from oxidation, and performing heat-treatment processes such as nitriding. It also supports temperature and pressure control during steel production.
What is the application of argon in steelmaking?
Argon is used in secondary refining processes such as AOD (Argon Oxygen Decarburization) to support degassing, carbon control, and prevent nitrogen pickup. It improves homogenization of molten steel and ensures better chemistry control.
Is hydrogen used in steelmaking?
Yes. Hydrogen is used as a clean alternative fuel, especially in direct reduced iron (DRI) technologies, enabling the production of low-carbon “Green Steel.” It is also used in specific heat-treatment processes.
Do industrial gases used in steelmaking need high purity?
Yes. High purity is required because impurities negatively affect steel quality and process stability. ParsiaGas supplies industrial gases with strict purity levels (up to 99.999%) in cylinders or certified bundles.
What packaging options are available for steelmaking gases?
Industrial gases for steel production are supplied in high-pressure cylinders, multi-cylinder bundles, and bulk cryogenic tanks depending on consumption volume. ParsiaGas supports all three delivery methods.
How should steelmaking gases be stored and handled safely?
Cylinders must be stored upright in a dry, cool, and ventilated area, away from heat sources and open flames. Use proper regulators and fittings specific to each gas. Ensure ventilation when handling inert gases such as nitrogen and argon to prevent asphyxiation.
