Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). [1] They are used in the production of steels and alloys.
FACOR, Sriramnagar. The Ferro Alloys Corporation Limited (FACOR) was floated in 1955 by the house of Sarafs and Mors to become the first major producer of ferromanganese in India.
History of ferroalloy production in Orava region in Slovakia begins in 1952, when the company Kovohuty Istebné was founded, with main production programme being the production of ferroalloys in electric arc furnaces. In 1954, new ferromanganese factory was opened in Istebné (Orava)Istebné (part of [[Orava ]]).
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 1998, the Ukrainian Association of Ferroalloy Manufacturers (UkrFA) was established, which included the plant. [5] In September 2005, the plant began production of ferrosilicoaluminum (composed of 15–20% aluminum and 50–70% silicon), which was mastered on the furnace No. 1, which previously produced ferrosilicon.
The history of ferrous metallurgy in the Indian subcontinent began in the 2nd millennium BC. Archaeological sites in the Gangetic plains have yielded iron implements dated between 1800 and 1200 BC. [24] By the early 13th century BC, iron smelting was practiced on a large scale in India. [24]
In 1958 the USSR council of ministers gave a decree for the construction of a manganese ferroalloy plant at Nikopol in Ukraine. Including the factory buildings a water supply and electricity supply had also to be built. By 1966 the factory was sufficiently complete for the first tapping of No.1 furnace. [5]
Murex was founded in 1909 as an iron founder and a ferroalloy manufacturer. The company moved to Rainham, Essex in 1917. [1]In the 1930s, Murex made large quantities of electrodes at their factory in Waltham Cross, [2] and many ships including HMS Ark Royal and Queen Elizabeth 2 have been welded using Murex equipment.
