Product Details

Ferro Aluminium Tailored Refractory Materials Iron and steel smelting

 

Product introduction  

 

Aluminum (Al) is used for deoxidizing and grain refining in steels. It is a strong deoxidizer. It is also used as nitride former and as an alloying agent. Its ability to scavenge nitrogen (N) from steel makes it a useful addition in drawing quality steels, especially for automotive applications.

Al plays an important role in secondary metallurgy. It forms alumina (Al2O3) and decreases the amount of oxygen in the steel during the production of killed steels.

Metallic Al is the most common addition agent. Purity of deoxidation grade of Al is normally over 95 % with the main tramp elements being zinc, tin, copper, magnesium, lead and manganese. Coiled aluminum wire is usually made to 99 % minimum specification.

Al is also added as ferro-aluminum which is a dense and highly efficient form of aluminum addition. Ferro-aluminum contains 30 % to 40 % Al and normally added in lump form.
