Ferroalloys
This is achieved through carbothermic reduction. For this process, a mixture of manganese oxide, iron oxide and carbon is heated. ... Ferrovanadium. Ferrovanadium is an alloy which consists of 35 – 85 % of vanadium. Vanadium has the property of deoxidizing steel.
SciELO
Throughout carbothermic tests via thermogravimetry, it was stated that the optimal content of petroleum coke (fixed carbon = %; ashes = %) used in the mixtures varies from 10 to 15%, in weight. It was verified that the oxide reduction occurs from 900ºC, which is linked to the effective beginning of the petroleum coke gasifiion reaction.
Ferroalloys
Ferrovanadium. Ferrovanadium is a ferroalloy containing 35 45 % V, 13 % Si, % Al (Fe and impurities balance). Appliion. Ferrovanadium is used in ferrous metallurgy for alloying steels, alloys and cast iron to obtain finegrained structure, increase toughness and steel resistance to alternating loads as well as improve hardenability.
