Ferrotungsten Is An Alloy Of Tungsten And Iron
It is used in steelmaking and casting as an additive for tungsten, which is one of the most important alloying elements in the production of special steels.
Tungsten can not only reduce the elongation of steel to a small extent, but also increase the strength limit and yield point of steel. It can also improve the hardness and wear resistance of steel.
Of particular importance is the good influence of tungsten on the high-temperature mechanical properties of steel, which improves heat resistance and tempering stability.
The most common method of producing ferrotungsten is the "blocking method", which uses carbon to reduce the oxides in the concentrate in an electric furnace, and then removes the solidified metal blocks from the furnace.
There are also iron digging methods and thermite method. Ferrotungsten is a legally inspected commodity.
