Vanadium is used in producing rust resistant and high speed tool steels. It is an important carbide stabilizer in making steels. About 80% of the vanadium now produced is used as ferrovanadium or as a steel additive. Vanadium foil is used as a bonding agent in cladding titanium to steel. Vanadium pentoxide is used in ceramics and as a catalyst.

g is the gravitational acceleration in m/s 2, and. r P is the pitch diameter in m.. The optimum of Fr p is between 1.6 and 2.0. The milling capacity for Fr p outside this range is lower despite the constant energy consumption of the pulverizer.. Tests carried out for some industrial mills have proven that the change of grinding unit rotational speed strongly influences mill capacity.

Vanadium. Vanadium is alloyed with steel to act as a deoxidizer and cleanser and produces a fine-grained steel. When used with tool steel it resists shock and jarring better than straight carbon steel. Silicon. Silicon has about the same effect on steel as manganese, in that it acts as a purifier and cleanser.

Ferrosilicon–vanadium alloys can be produced by smelting in an electric arc furnace. By controlling the amount of carbonaceous reductant, ferrosilicon–vanadium alloy compositions are produced, as shown in Table 10.7. If silicon iron is used as reducing agent, the content of C in the silicon–vanadium alloy is <0.5%.
