Metals

Air Liquide supplies argon and nitrogen for the ladle metallurgy furnace to stir and refine the melted steel.

Our SPAL technology helps producers of steel products to melt cleaner metals to produce castings with fewer defects, enhanced mechanical properties and lower amounts of rejects.

Air Liquide supplies oxy-fuel combustion solutions to maximise productivity of Electric Arc Furnaces (EAF's) at steel mills.

Air Liquide’s oxygen, related equipment and services, support combustion applications such as ladle heating and billet/slab reheating.

A reliable supply of industrial gases for steel manufacturers via bulk deliveries, cylinders and on-site production units operated by Air Liquide.

Air Liquide supplies argon and nitrogen for the ladle metallurgy furnace to stir and refine melted steel.

Air Liquide’s oxy-fuel and air oxy-fuel combustion units are available as rotary or reverberatory furnaces for non-ferrous metals.

Using a 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

High oxygen levels are used for primary smelting. Reducing the nitrogen content of the off-gas reduces the heat losses while increasing the reaction temperature and reaction rate.

Extrusion die inerting for aluminum extrusion presses can increase productivity and reduce oxidation related defects.

Supplying industrial gases for casting applications such as caster shrouding. We have developed a technology that create cleaner metal for castings with fewer defects and lower rejects.

We use aluminum extrusion to reduce oxygen concentration at die to control deposit reaction. In addition to nitrogen supply, we provide atmosphere analysis services for this application.
