Ferroalloy representation: all kinds of ferroalloy product grades that way to write x (a) x (b) x (c) x (d) in the following format. It represents the highest percentage of impurity elements and or groups. A front element (or compound) and percentages. Ferroalloy products represent the elements iron deoxidizer manufacturers, the chemical element symbol "Fe" indicates. Ferroalloy products represent processes and product characteristics. Simply Deoxidizer suppliers, blast furnace method is the use of blast furnace temperature and reducing atmosphere is made of the alloy ferroalloy ore reduction. In the blast furnace ferroalloys mainly carbon ferromanganese; the electric energy as a heat source to buy deoxidizer, carbon is used as a reducing agent, and the reducing power of carbon is enhanced with increasing temperature, it is much more difficult to restore oxides such as CaO , Al2O3, rare earth oxides, etc. can restore them in reducing electric furnace.
