What are Ferro Alloys?
Ferroalloys like ferrosilicon, ferromanganese, and ferrotitanium are added to the furnace during the production of steel in small and precise quantities for specific improvements in steel properties.
For ferroalloy production, a submerged Electric Arc Furnace (EAF) is used, loaded with selected and sized raw materials such as quartz, wood, charcoal, and ores. During the process, these raw materials melt and chemically react. The product that leaves the furnace is a molten metal, including silicon, ferrosilicon, ferronickel, thermal phosphorus, and zirconium. These molten metals are cooled and further processed into the appropriate size and grade for various applications.
About 85% to 90% of all ferroalloys are used in steelmaking; the remaining ferroalloys are utilized in nonferrous alloys (e.g., nickel or titanium-based) and by the chemicals industry.
