We produce different kinds of manganese compounds, mainly for the steel industry.
FERROGLOBE OFFERS A WIDE RANGE OF FERROMANGANSE AND SILICOMANGANESE PRODUCTS WHICH BOOST THE QUALITY AND PROPERTIES OF STEEL .
More than 90% of the manganese ore mining worldwide goes to producing steel in the form of ferroalloys. Manganese alloys are produced by a carbothermic reduction of Manganese Ore and quartzite as a source of silicon.
What varieties are used?
A variety of manganese products can give steel different properties:
Ferromanganese is used as deoxidiser, desulphuriser and degasser of steel, to eliminate nitrogen and other hazardous elements that are found at the first melting of iron. It also improves mechanical properties such as hardenability and abrasion resistance from special steels. Nowadays, three grades of ferromanganese are applied in a large and growing number of industrial and consumer products:
Ferromanganese MC (FeMn MC)
Ferromanganese LC (FeMn LC)
Ferromanganese HC (FeMn HC)
Silicomanganese is used as a steel deoxidiser and allows for production of low carbon steel grades and other fine steel products such commonly found in long steel products for construction. Three main grades are produced:
