Ferrovolfram FV70 GOST is an alloying alloy of iron and tungsten, which is obtained by a chemical reduction reaction. It is represented by several brands. The products are regulated by the norms of GOST 17293-93.
Depending on the brand, the proportion of tungsten in the alloy ranges from 65 to 85%. Ferroalloy includes up to 7% molybdenum, as well as impurities of copper, arsenic, tin and other elements.
Ferrovolfram has a multiphase structure and may contain a solid solution of iron in tungsten, intermetallic iron and tungsten, a phase of pure tungsten.
In industry, ferroalloy is obtained from the minerals scheelite, wolframite, hubnerite and ferberite. It belongs to refractory alloys, so its mass is scooped out of the furnace or smelted "on the block" in continuous cycles.
There are 2 production methods:
Aluminothermically — this is how ferrovolfram and tungsten ligatures with nickel and chromium are obtained.
Electrothermically — this is how tungsten oxides are reduced using aluminum, silicon and carbon.
Ferrovolfram is used in metallurgy for alloying steels and alloys. In combination with other components, it is used in the manufacture of structural, magnetic, heat-resistant and high-speed steels. Ferroalloy is used in the smelting of steels with a fine-grained structure. Such steel acquires additional strength and elasticity. High-speed cutting tools are made of steel with a high content of tungsten, which work at high speeds and high temperatures.
