Glass & Metals

Industrial gases are critical in the glass and metals industries, enabling efficiency, quality, and innovation. Oxygen enhances combustion processes for glass melting and metal cutting, while argon ensures precision and protection in welding and metal fabrication. Hydrogen is used for annealing and reducing impurities, while nitrogen and carbon dioxide improve cooling and finishing processes. These gases empower manufacturers to produce durable, high-performance materials that drive industrial and technological progress.

Steel & Metal Production:

• Oxygen is used in blast furnaces and basic oxygen furnaces (BOFs) to refine iron into steel, Enhancing burning efficiency in electric arc furnaces (EAFs), reducing carbon content in metals.

• Oxygen enrichment in cement and asphalt kilns boosts combustion efficiency, reducing fuel consumption and emissions.

Glass Manufacturing:

• To ensure high-quality, defect-free glass production. During manufacturing, molten glass is floated on a bath of molten tin, but exposure to oxygen can cause tin oxidation, leading to surface imperfections. To prevent this, a controlled hydrogen-nitrogen atmosphere is introduced into the tin bath. Hydrogen removes residual oxygen, preventing tin oxide formation and ensuring a smooth, optically clear glass surface. This process enhances glass quality, improves energy efficiency, and reduces production defects, making hydrogen essential for modern float glass production.

• Argon-filled double-pane and triple-pane windows enhance thermal insulation and reduce energy loss in buildings.
