Air Liquide’s patented Expanding Gas Air Liquide (EGAL) process, derived from SPAL technology, uses liquid cryogenics (argon or nitrogen), to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen, water vapor, and carbon dioxide during air melting operations.
Our SPAL technology helps producers of non-ferrous products to melt cleaner metals to produce castings with fewer defects, enhanced mechanical properties and lower rejects. SPAL, Air Liquide’s technology family of inert blanketing processes, include EGAL and Surface Backfilling Air Liquide (SBAL). Contact us to learn more about these patented processes.
Air Liquide has developed BOOSTAL™ offers for the metals industry, which include oxygen supply, patented burners, and expert support for the implementation of oxy-combustion technologies suitable for all steps in the manufacturing process.
