Argon

It is generally used to prevent contact, hence interaction, between liquid metal and the surrounding atmosphere. Applications include melt stirring, tun dish purging to prevent steel re-oxidation and secondary steel refining in vacuum degassers, such as the VOD, RH, RH-OB. However, the largest quantities of argon are consumed in the AOD process for decarburising raw high-chromium steels while minimizing the chromium oxidation.

Carbon Dioxide

CO2 is typically used for environment protection. CO2 is used for red fume suppression during hot metal transfers, for nitrogen pick-up reduction during EAF tapping and for bottom stirring. In the non ferrous metallurgy, it is used for fume suppression during ladle transfer of matte (Cu/Ni production) or bullion (Zn/Pb production). Small amount of liquid CO2 can be used in processes incorporating carbon dioxide pre-treatment to enhance restoration of acidified water from Acid Mine Drainage (AMD).

 

ALTOP™ represents a revolution in the packaging of gases. It is a ready-to-use system for cylinders containing oxygen, acetylene, pure argon and mixtures.

 

ALTOP™ integrates the valve, the regulator and an emergency cut-off system inside a protective guard.
