Silicon ferroalloy consumption is driven by cast iron and steel production, where silicon alloys are used as deoxidizers. Some silicon metal was also used as an alloying agent with iron. On the basis of silicon content, net production of ferrosilicon and miscellaneous silicon alloys in the US was 148,000 t in 2008.
The Submerged-arc furnace for phosphorus production is a particular sub-type of electric arc furnace used to produce phosphorus and other products. Submerged arc furnaces are mainly used for the production of ferroalloys. The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden.
Ferrophosphorus is a ferroalloy, an alloy of iron and phosphorus.It contains high proportion of iron phosphides, Fe 2 P and Fe 3 P. Its CAS number is 8049-19-2. The usual grades contain either 18 or 25% of phosphorus. [1]
Ferrochrome alloy. 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.
The chemical reaction uses sodium hydroxide (NaOH), ferrosilicon, and water (H 2 O). While in the "silicol" process, a heavy steel pressure vessel is filled with sodium hydroxide and ferrosilicon, and upon closing, a controlled amount of water is added; the dissolving of the hydroxide heats the mixture to about 200 °F (93 °C) and starts the ...
Ferromanganese is an alloy of iron and manganese, with other elements such as silicon, carbon, sulfur, nitrogen and phosphorus. [1] The primary use of ferromanganese is as a type of processed manganese source to add to different types of steel, such as stainless steel. Global production of low-carbon ferromanganese (i.e. alloys with less than 2 ...
Ferroaluminum (FeAl) is a ferroalloy, consisting of iron and aluminium.The metal usually consists of 40% to 60% aluminium. Applications of ferroaluminum include the deoxidation of steel, [1] hardfacing applications, reducing agent, thermite reactions, AlNiCo magnets, and alloying additions to welding wires and fluxes.

Ferrovanadium and other vanadium alloys are used in carbon steel, alloy steel, high strength steel, and HSLA (High Strength Low Alloy) steel. [9] These steels are then used to make automotive parts, pipes, tools, and more. [6] The addition of ferrovanadium toughens the steel making it more resistant to temperature and torsion. [2]
