ferrovanadium

[¦fe·rō·və′nād·ē·əm]
(metallurgy)
An iron alloy high in vanadium (35-55); used to add 0.1-2.5% vanadium during the manufacture of engineering steels and high-strength steels.

Ferrovanadium

 

a ferroalloy consisting of 35–45 percent V, 1–3 percent Si, and 0.5–1.5 percent Al (Fe and impurities constituting the remainder). Ferrovanadium is produced in electric furnaces through the silicothermic method using the vanadium pentoxide (85–95 percent V2O5) obtained in the chemical and metallurgical treatment of iron-vanadium concentrates. It is used mainly for alloying steel. Related products include silicovanadium, which is produced in electric furnaces, and metallic vanadium and rich ferrovanadium (up to 80 percent V), which are obtained by nonfurnace aluminothermy.

3], complete recovery of vanadium from the iron-vanadium concentrate up to ferrovanadium constitutes less than 50 %, whereby the highest losses occur at the stage of recovery from the vanadium slag of vanadium pentoxide.
If increase of titanium content in ferroalloy enables reduction of its density and melting point of the alloy changes insignificantly [8], in melting of ferrovanadium, ferroniobium and ferromolybdenum sharp increase of temperature of alloys is observed as content of the main alloying element increases, which causes reduction of the pool dimensions and need to reduce optimum mass of the metal being remolten.
