Ferroalloys an overview ScienceDirect Topics,Ferroalloys are usually classified in two groups: bulk (major) ferroalloys (produced in large quantities) and minor ferroalloys (produced in smaller quantities, but of a high importance). Bulk ferroalloys are used in steelmaking and steel or iron foundries exclusively, whereas the use of special ferroalloys is far more varied. About 85% to 90% of all ferroalloys are used in steelmaking; the

IMPURITIES IN COMMERCIAL FERROALLOYS AND ITS INFLUENCE ,It was concluded that high purity Fe-Si additions resulted in higher steel cleanliness. However, the inclusions in FeCr were not inherited to the liquid steel in laboratory based experiments. The literature concerning the influence of other ferroalloys on steel cleanliness is very scarce. In the present scenario, the ferroalloy manufacturer provides only partial information about the
