    en.wikipedia.org/wiki/Ferrochrome

    Ferrochrome or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight. [ 1 ] [ 2 ] Ferrochrome is produced by electric arc carbothermic reduction of chromite .

    FerroChrome factory of Elbasan. The FerroChrome factory in Elbasan started to operate in 1989. It is designed to produce high-carbon ferrochrome using as raw chromium material coming from the mines in the country, mainly from the Bulqiza area. Currently the Ferro-Chrome Factory of Elbasan works with two furnaces.

  5. Chromite - Wikipedia

    en.wikipedia.org/wiki/Chromite

    Production of ferrochrome is observed to emit pollutants into the air such as nitrogen oxides, carbon oxides and sulfur oxides, as well as dust particulates with a high concentration of heavy metals such as chromium, zinc, lead, nickel and cadmium. During high temperature smelting of chromite ore to produce Ferrochrome, Cr-III

    It is usually found as the mineral chromite, from which ferrochrome is produced in a smelting process. Rank Country/Region Chromium ore production (tonnes)

  7. Cementite - Wikipedia

    en.wikipedia.org/wiki/Cementite

    In the iron–carbon system (i.e. plain-carbon steels and cast irons) it is a common constituent because ferrite can contain at most 0.02wt% of uncombined carbon. [6] Therefore, in carbon steels and cast irons that are slowly cooled, a portion of the carbon is in the form of cementite. [ 7 ]

    The solution can be used on cast iron and mild low-carbon steel. The resulting finish complies with military specification MIL-DTL–13924D Class 4 and offers abrasion resistance. Black oxide finish is used on surgical instruments in light-intensive environments to reduce eye fatigue.

    The squareness ratio is low, around 0.75, resulting in early but smooth onset of distortion. [37] These tapes, historically labeled and sold as 'low noise', have high levels of hiss and relatively low sensitivity; their optimal bias level is 1–2 dB lower than that of the IEC reference tape.
