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 plants at Sriramnagar have facilities for raw material handling, metal, and slag casting, crushing, sizing and other ancillaries apart from furnaces for the smelting of ferroalloys. The raw materials are manganese ore, chromite and quartzite ores with principal elements of manganese, chromium and silicon respectively.
Zaporizhzhia Ferroalloy Plant (OJSC) produces ferrosilicon (47.7% of the Ukrainian market), carbon ferromanganese, and metallic manganese (100% of the Ukrainian market) [2] which are used in the metallurgical industry for alloying of steel, alloys, and cast iron. Suppliers of raw materials include Ukrainian companies: Pokrovsky GZK, Marganetsky ...
Pig iron is known as 'raw iron', while wrought iron is known as 'cooked iron'. By the 1st century BC, Chinese metallurgists had found that wrought iron and cast iron could be melted together to yield an alloy of intermediate carbon content, that is, steel. [40] [41] [42]
Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, calcium silicides, and many other materials are used for the same purpose. [5]
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.

In the troubled times of the 1990s brought about by the collapse of the Soviet Union and Ukrainian independence the factory had difficulty obtaining raw materials, and even the electricity to power the furnaces was in short supply. Nevertheless, by 2004 furnace No. 14 produced its first million tons of alloy. [6]
Stakhanov Ferroalloy Plant (Ukrainian: Стахановський завод феросплавів, romanized: Stakhanovskyi zavod ferosplaviv) is the largest (about 50% of all-Ukrainian production) plant for the production of ferrosilicon [2] in Ukraine.
