Gas solutions for smelters and foundries
Air Liquide supplies industrial gases and oxy-fuel burners for casting processes, e.g. ladle preheating and melting.
Air Liquide's EGAL (Expanding Gas Air Liquide) process uses liquid gases, argon and nitrogen, to limit the contact between molten metal and the gases in the air, such as oxygen, nitrogen and water vapour, during the melting process.
Air Liquide's SPAL technology for inerting the melt results in fewer defects and improved mechanical properties of the metal as well as reduced cassation during casting.
