Liquid oxygen for metal smelting is a core combustion-supporting gas for the iron and steel, non-ferrous metallurgy and other industries. Leveraging its high-purity oxygen content and low-temperature liquid storage & transportation properties, it serves as the key raw material for oxygen-enriched combustion and is integrated into the entire melting and refining processes. It addresses the pain points of insufficient combustion, inadequate furnace temperature and low smelting efficiency associated with traditional air-based combustion support.
Whether for converter steelmaking in iron and steel production, non-ferrous metal melting, special alloy refining or waste metal recycling, liquid oxygen precisely meets the combustion-supporting requirements of various smelting processes, improves the quality and production efficiency of metal finished products, and has become a pivotal choice for the metal smelting industry to enhance quality and efficiency, save energy and cut costs.

I. Core Applications: Precisely Adapted to Four Major Smelting Scenarios
Iron and Steel Smelting: In converter and electric arc furnace steelmaking, oxygen-enriched injection of liquid oxygen increases the oxygen concentration in the furnace, rapidly raising the furnace temperature to above 1600℃ and shortening the smelting cycle. It is ideal for large-scale steelmaking production, effectively boosting the output and purity of molten steel.
Non-Ferrous Metal Smelting: During the melting of copper, aluminum, zinc and other non-ferrous metals, liquid oxygen-supported combustion enables full fuel combustion, reduces the formation of furnace impurities and flue gas, lowers metal oxidation loss, and improves the purity and recovery rate of finished products.
Special Alloy Refining: In the refining of high-temperature alloys, stainless steel and other premium alloys, liquid oxygen precisely regulates combustion intensity, ensures stable and uniform furnace temperature, and prevents alloy composition segregation, meeting the sophisticated requirements of high-end alloy smelting.
Waste Metal Recycling: When remelting waste steel, aluminum and other scrap metals, liquid oxygen resolves the issue of insufficient combustion of waste materials. It rapidly melts raw materials while reducing harmful emissions, enhancing the smelting efficiency and environmental performance of recycled metal production.

II. Core Values: Why It Becomes the Mainstream for Metallurgical Combustion Support?
High-Efficiency Combustion & Yield Boost: With a purity of ≥99.6%, liquid oxygen enables oxygen-enriched combustion to increase furnace combustion efficiency by more than 30% and shorten the smelting cycle by 20%-25%, significantly raising furnace capacity.
Remarkable Energy Saving & Cost Reduction: It cuts the consumption of fuels such as coke and pulverized coal by 15%-20%, while reducing flue gas emissions and the associated environmental treatment costs, driving a more than 25% increase in comprehensive production efficiency.
Quality Improvement, Purification & Loss Reduction: Complete combustion reduces furnace inclusions and metal oxidation loss, increases the qualification rate of metal finished products by 10%-15%, and minimizes raw material waste.
Flexible Storage/Transport & Stable Supply: Liquid storage and transportation feature high oxygen density; matched with vaporizers, it achieves on-demand gas supply and adapts to furnaces of various specifications. Large smelters can build storage tanks to realize continuous and stable gas supply for production.
III. Selection Essentials: 3 Steps to Choose the Right Liquid Oxygen Solution for Smelting
Clarify Requirements: Determine liquid oxygen consumption and gas supply pressure based on furnace type (converter/electric arc furnace) and smelted metal type. For large-scale smelting operations, calculate oxygen supply according to hourly melting capacity.
Select Supporting Equipment: Match with dedicated liquid oxygen vaporizers and high-temperature resistant delivery pipelines. Large-scale enterprises are recommended to equip with an intelligent gas supply system to achieve precise regulation of oxygen supply volume.
Choose a Reliable Service Provider: Prioritize brands with formal industrial gas qualifications and proven project cases in the metallurgical industry. The provider should offer door-to-door delivery, storage tank maintenance and emergency gas supply services to ensure uninterrupted production.
