Melting and casting

We supply industrial gases to ferrous and non-ferrous foundries for casting applications, including tundish inerting, caster shrouding, shell casting, investment casting and sand casting. 

Air Liquide’s oxy-fuel and air oxy-fuel combustion units are available as rotary furnaces and reverberatory furnaces for aluminum, lead, copper, brass and iron.  We help manufacturers improve production performance and save energy.

Air Liquide’s SPAL technology uses liquid cryogenics, i.e. argon or nitrogen, to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen and water vapor during air melting operations. This SPAL technology allows steel manufacturers to producing castings with fewer defects, enhanced mechanical properties and lower rejects.
