Air Liquide in the value chain

Casting

We supply industrial gases for casting applications such as tundish inerting and caster shrouding. Air Liquide’s patented Expanding Gas Air Liquide (EGAL) process uses liquid cryogenics, argon or nitrogen, to reduce interactions between molten metal and atmospheric gases such as oxygen, water vapor, and carbon dioxide during air melting operations. Our SPAL technology allows foundries to melt a cleaner metal for producing castings with fewer defects, enhanced mechanical properties and lower rejects.
